Description

REPAIRING MATERIAL, REPAIRING STRUCTURE, AND REPAIRING METHOD}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a repairing material, a repairing structure, and a repairing method of a pipeline, and in particular, the installation has already been completed, such as a sewer pipe, a rainwater pipe, and a tunnel of various transportation systems. In the case of aging pipes (hereinafter referred to as "installed pipes" (hereinafter referred to as "pipe pipes")), which are aging, it is possible to install repairing materials and repairing materials for repairing the installed pipes. The present invention relates to a repair structure and a method of installing a repair material in an installed pipeline.

If the installed pipelines, such as sewer pipelines, rainwater pipelines, and tunnels of various transportation systems, are aged, it is necessary to repair them according to the degree of deterioration or aging. If the degree of deterioration of the pipeline is slight, it is possible to repair by applying mortar or the like partially on the surface.

However, when the degree of deterioration is not small or extensive, it is necessary to repair the entire deteriorated pipeline with a repair material. In particular, when repairing a large diameter installed pipeline, it is effective to repair the entire pipeline with a repair material, and a repair material and a repair method for repairing the entire pipe are required. As a prior art, several methods of repairing an installed pipeline, such as a large sewage pipeline, are known.

For example, Japanese Unexamined Patent Application Publication No. 8-277992 discloses spirally wound reinforcing steel bars such as piano wires and the like along the inner surface of a pre-installed tube, and spirally strips a band-shaped resin plate thereon. To form a cylinder-type liner, ie a cylinder-shaped shape, ie, a shape of a rotating body about an axis, hereinafter referred to as a " cylindrical shape " A method of injecting a curable filler such as mortar (lime ash; 灰 三 物; mortar or cement poured into a crack in a stone brick construction) is described.

However, this method is applied to repair a buried pipe because reinforcing bars such as piano wires are not bonded to a plastic plate, and as a result, the resin plate itself is not reinforced. Cracks occur in the curable filler, such as a mortar layer, when it passes or when vibration occurs due to an earthquake or the like.

Thus, the groundwater is submerged in the cracks, and the external water pressure acts directly on the resin plate, whereby the resin plate may protrude to the inner surface side of the pipe in a place where the adhesive strength between the curable filler layer such as mortar and the resin plate is weak.

In addition, Japanese Laid-Open Patent Publication No. 10-166444 discloses a longitudinal reinforcing agent in which steel bars are contained in a strip-shaped plastic resin plate formed in a tubular liner, which is wound spirally in an installed tube. Is connected, and the resin plate is wound spirally along the inner tube surface to form a liner, and a method of injecting ash powder such as mortar between the liner and the inner tube surface is described.

In this method, however, the resin plate is previously incorporated with the reinforcing material including the reinforcing bar. However, since the resin plate needs to be wound in a spiral manner in the installed pipe, it is impossible to use a material having sufficient rigidity as the reinforcing material. If the strength of itself is weak, the reinforcement against the pressure of the soil is insufficient.

Although the conventional repair methods according to these installed pipe lines all use reinforcing bars to increase the strength of the pipes after repair, the resin plates cannot be sufficiently reinforced. Furthermore, when injecting mortar or the like between the installed pipe and the liner, a support hole for supporting reinforcement is assembled on the inner surface of the liner so as not to deform the spirally wound resin plate due to the pressure. It is necessary to take measures to add injections by mortar or mortar several times. As a result, construction is complicated and the time required for construction is long.

On the other hand, a method of laying a lining material along an inner surface of a pipe provided as a prior art and injecting and curing hard ash, such as mortar or cement milk, between a gap between the inner material and an inner surface of the provided pipe is known.

In such a conventional method, for example, as disclosed in Japanese Patent Application Laid-Open No. 63-88388, an injection hose is inserted into a tubular gap or gap formed between an inner surface of an installed pipe and an interior material. Is inserted, the openings at both ends of the axial direction are sealed with mortar in the cylindrical gap, and in the state, ashes are injected into the cylindrical gap through the injection hose.

However, the conventional technique of injecting ginseng water in the state which sealed the opening part of both ends by mortar in the clearance gap between the inner surface of an installed pipe and a built-in material does not inject the ginseng water for the period until the sealing mortar hardens, In addition, since the sealing caused by the mortar may collapse due to the pressure generated when the ash is injected into the gap, the injection of the ash is to be performed at a low pressure.

In addition, if water flows on the inner surface of the installed pipe, it is not easy to completely seal it with mortar, and may cause a case in which ash ginseng flows out of a part of the seal. Due to the above-mentioned problems, the conventional method of sealing both ends of the gap using mortar has a problem that the injection efficiency of the ash ginseng is not excellent, requiring a long time.

In order to solve these problems of the prior art, the present inventors can prevent the external water pressure directly acting on the inner surface members such as the resin plate forming the inner surface of the pipe after repair, and can sufficiently reinforce the installed pipe itself even if the strength of the installed pipe itself is weak. In the case of injecting a curable filler such as mortar, reinforcement measures such as assembling a support reinforcement member are unnecessary, and the repairing method of the installed pipe line and the repairing material used in the method can be easily installed. It aims at providing the repair structure of the pipeline obtained by the method.

In addition, the end portion of the opening to be injected with the ginseng can be reliably sealed without being affected by the internal condition of the installed pipe, whether or not there is water flowing in the pipe, and the ginseng can be injected stably at high pressure. Another object of the present invention is to provide a structure for injecting an end portion of a conduit for repairing pipes to stably improve the quality of ash after curing.

In order to achieve the above object, the installed pipeline repair method according to the present invention using a reinforcing member which can be carried in the installed pipeline, the hollow frame-shaped reinforcement in the middle along the inner surface of the installed pipeline (1) ) After assembling, a plurality of inner surface members 3 are installed inside the reinforcement 1 (ie, at the center of the pipeline) and fixed in a cylindrical shape in the axial direction of the pipeline. After assembling, the curable filler is injected into the gap between the inner surface member 3 and the inner tube surface.

In addition, the method according to the present invention minimizes the gap between the outer periphery of the reinforcement and the inner surface of the underground pipe around the outer side of the reinforcement (ie, the inner wall side of the conduit).

A reinforcement body 1 forming a hollow frame structure and a fitting portion 110 are provided on an inner circumferential side of the ring-shaped reinforcing member 11, and the ring-shaped reinforcement body 1 and a plurality of fitting members are provided. (2), the first fitting portion 2a fitted to the fitting portion 110 of the ring-shaped reinforcing member 11 on the outer side (ie, the inner wall side of the pipe) of the fitting member 2 is provided. And a second fitting portion 2b is formed at an inner side (ie, a pipe center side) of the fitting member 2, and the second fitting portion is formed at the plurality of fitting members 2 and an outer surface or an end thereof. Alignment portions 31a and 31b for fitting (2b) are formed to form a plurality of inner surface members 3 having a smooth inner surface. It features.

In using such a fitting member, it is preferable that each of the fitting members is a longitudinal continuous member that is continuous in the axial direction of the pipe provided. In addition, it is preferable that the inner surface member used for the repair conduit for repair of the conduit provided in the present invention is a member of an axial shape continuous in the axial direction of the conduit.

Moreover, as a preferred embodiment of the repairing material of the present invention, a plurality of ring-shaped reinforcing members divided along the inner circumference of the installed pipes are disposed to each other for the purpose of arranging at predetermined intervals in the axial direction of the pipes provided as the reinforcing bodies. It is more preferable to have a plurality of connecting members which are connected and integrated.

In addition, in the repairing material according to the present invention, it is preferable to form concavities and convexities for forming grooves in the form of grooves continuous in the axial direction of the pipeline at least provided around the outer periphery of the reinforcement, and separately or in addition thereto, the pipeline axis provided in the reinforcement. It is preferable to form a hole penetrating in the direction.

In addition, the repairing material of the present invention can be installed and fixed around the outer side of the reinforcement, and the clearance gap member that can reduce or eliminate the gap with the inner surface of the installed pipeline by installing and fixing the reinforcement to the reinforcement. Can be included. Thus, the repair structure of the pipeline according to the present invention is a repair structure of the pipeline after being repaired according to the installed pipeline repair method according to the present invention, wherein a plurality of inner surface members continuous along the inner surface of the pipe installed in the installed pipeline are axially oriented. It is a state arranged in a cylindrical shape extending along the, characterized in that the curable filler is filled between the inner surface member and the inner surface of the pipe line installed and fixed to the reinforcement.

In addition, in the repair structure of the pipeline according to the present invention, the inner member for the reinforcement may be installed and fixed through a plurality of fitting members 2 mounted inside the reinforcement, and the fitting member 2 may be used. In the case of using, it is preferable that the fitting member 2 is formed of a longitudinal continuous member that is continuous in the axial direction of the installed pipe.

Furthermore, in the repair structure of the pipeline according to the present invention, a plurality of ring-shaped reinforcing members obtained by dividing the reinforcement along the inner circumferential surface of the pipe, and the respective ring-shaped reinforcing members are connected in the axial direction of the installed pipeline. It is preferable to include a plurality of connecting members to integrate.

Further, in the repair structure of the pipeline according to the present invention, a hole penetrating in the axial direction of the pipeline provided in the reinforcement, that is, a hollow skeleton structure is formed, and the structure in which the curable filler is filled into the hole is provided. It can be preferably employed.

Moreover, in the repair structure of the pipe line which concerns on this invention, the structure which interposed the cylindrical outer surface material along the inner surface of the said installed pipe between the reinforcement body and the installed pipe inner surface can also be employ | adopted.

The present invention is to install and fix the inner surface member forming the surface (inner surface) of the pipe after repair, to the reinforcement assembled in the form of hollow frame along the inner surface of the installed pipeline, thereby having sufficient strength required by the reinforcement furnace In order to achieve the desired purpose by receiving the force acting on the inner surface member to the reinforcement.

Here, the means for installing and fixing the inner member on the reinforcing member according to the present invention is not particularly limited, but the inner member and the fitting member (2) are sandwiched by using the inner and outer members and the concavities and convexities provided in the reinforcing member in advance. ) May be coupled to each other via a panel or by using a screw or the like.

The repairing method of the installed pipeline according to the present invention and the repairing material used in the repairing method are assembled to the reinforcement in the form of hollow frame along the inner surface of the divided reinforcing member, the shape of the reinforcing member according to the situation of the installed pipeline. Reinforcements with sufficient strength can be constructed in the installed pipelines according to the appropriate dimensions and damages, and even if the pipelines lose strength, they can be reliably reinforced. Strength can be exhibited.

Further, in the method of the present invention in which the reinforcing member is assembled into the reinforcement body in the form of a hollow frame into the installed pipeline, it can be easily applied to other cross-sectional pipelines such as a horseshoe pipeline. At the same time, since the strength of the reinforcing body can be sufficient, a material having good fluidity and low-flowability, such as mortar or air mortar having a high moisture ratio, can be selected and used as a curable filler (ash ash), and thus has excellent workability at low cost. Can be applied.

In addition, in the present invention, since the inner surface member is fixed to and supported by the reinforcement body, external water pressure or the like does not directly act only on the inner surface member, but also in the step of injecting the curable filler, the member for supporting reinforcement (支 保 工) ) It can be easily installed in a short time without the need to take additional measures to assemble, add and inject.

In another embodiment, a method and structure for installing and fixing an inner surface member by interposing a fitting member 2 with respect to a reinforcement body may be adopted, compared with a case in which the inner surface member is directly inserted into a rigid body reinforcement body. It is possible to have a margin in the dimensions of the engaging portion with the inner surface member to improve the workability and at the same time increases the degree of freedom to select the material of the inner surface member in accordance with the function required for the pipe line, for example, as the fitting member (2) When the thermoplastic resin molded article is used, it is also possible to use a rigid body for the inner surface member, thereby imparting a function such as flame retardancy to the water-retaining material.

Thus, in the case of using such a fitting member 2, a plurality of fitting members 2 continuous in the axial direction of the installed pipeline are employed to construct the repair structure of the pipeline of the present invention. It is possible to have a structure for reinforcing the inner surface member which is installed and fixed between the reinforcing members constituting the reinforcing body, thereby preventing deformation of the inner surface member and enabling the use of a thinner inner surface member. In addition, there is also an advantage that a seamless watertight structure can be obtained by using the fitting members 2 continuous in the axial direction of the installed pipe line by, for example, a length connecting the neighboring manholes.

In addition, as another embodiment of the present invention as a member that is continuous in the axial direction of the pipe provided as the inner surface member, a plurality of longitudinal continuum is adopted to assemble in a tubular shape, in the case of building the pipeline repair structure of the present invention A seamless pipe in the direction can be obtained, and the fluidity in the pipe can be particularly improved. Also, in this case, also for a release tube such as a horseshoe tube, a box calvert (spherical tube), or a tunnel having various other cross-sectional shapes, the inner surface member is divided into a plurality of pieces in the circumferential direction of the tube. The inner member having the same shape and dimensions as the cylindrical tube is applicable. Therefore, this invention can be arrange | positioned easily along the cross-sectional shape of a pipe, and improves workability.

Furthermore, as another embodiment of the present invention, if a plurality of ring-shaped reinforcing members divided along the inner circumferential surface of the pipe provided by the reinforcing body are arranged at predetermined intervals in the axial direction of the installed pipe line, it is effective to reinforce the external pressure of the pipe. You can get a pipeline to fight against. In addition, by integrating the ring-shaped reinforcing member in the axial direction of the pipe line provided by the connecting member and constructing a repair structure of the pipe line of the present invention, the center is formed in the installed pipe line to maximize the strength as a structure.

Furthermore, by adjusting the length of the connecting member between the ring-shaped reinforcing members, the gap shape between the ring-shaped reinforcing members can be made into an octagonal shape, and the pipe line provided can be prevented from bending. In addition, it is possible to cope with a step by forming an eight-shaped shape and an inverted eight-shaped shape.

In addition, by using the connecting member as another embodiment of the present invention, the ring-shaped reinforcing member is divided into three parts, for example, in the circumferential direction, and the split body and the connecting member are divided into three parts outside the conduit, for example, in the circumferential direction. It is possible to adopt a method of pre-combining partial reinforcements having a length that can be easily pulled into an installed pipe line, and pulling several of the partial reinforcements into the pipe line to shorten the assembly time. At the same time, when applied to a pipeline having a different cross-sectional shape, for example, corner parts, which are difficult to assemble, may be combined in advance outside the pipeline, thereby improving workability.

In addition, as another embodiment of the present invention, in order to reduce or eliminate the gap between the reinforcement and the inner tube surface provided by the gap filling member, the gap filling member is provided at the top of the reinforcing member so that the buoyancy at the time of injecting the curable filler This can prevent the reinforcement from rising. Further, by installing and fixing the gap filling member on the side of the reinforcing member, the reinforcing member is suppressed from being deformed in the up and down direction, and the reinforcing member is hardly deformed by being unfolded with respect to the installed inner tube surface.

In addition, as another embodiment of the present invention by installing a cylindrical outer surface material on the inner surface of the tube installed in advance, it is possible to prevent the curable filler from escaping out of the pipe even if the damage of the installed tube is severe, and the curable filler is groundwater Contact with can also be prevented. Therefore, it is possible to prevent the deterioration of the physical properties of the curable filler such as mortar in accordance with the situation of the pipe line provided. In addition, by using a water-permeable material for the outer material and using a cement-based material such as mortar for the curable filler, excessive moisture or air can be discharged out of the outer material by filtration during the injection of the curable filler, and the cement-based material in the outer material. Is in a compressed state, and forms a state that is not affected by groundwater even before fully cured, and can be sure to exhibit a high strength after curing.

Furthermore, in another embodiment of the present invention, if a groove-shaped unevenness continuous in the axial direction of at least one pipe line is provided at the outer circumference of the reinforcement body, the axial direction is between the inner circumferential surface of the installed pipe and the reinforcement body. Since a continuous gap is formed, the resistance can be reduced in the process of injecting a curable filler such as mortar. In addition, the formation of such irregularities is greatly effective for reducing the weight of the reinforcing body.

In addition, in the case where a hole penetrating in the axial direction of the pipe line is formed in the reinforcement as another embodiment of the present invention, the resistance at the time of injecting the curable filler is reduced as described above, and it is effective against the weight reduction of the reinforcement. By constructing the repair structure of the pipeline of the present invention by using the same reinforcing body, the bonding force between the curable filler and the reinforcing body can be increased by the anchor effect caused by the holes of the reinforcing body and the curable filler solidified therein.

However, there is an advantage that the inner surface member can be improved in the axial direction of the installed pipe line so that there is no seam in the axial direction of the pipe line, thereby improving the flow capacity of the inner pipe member, and the fitting member 2 for installing the inner surface member to the reinforcement body has an advantage. Also, by continuing in the axial direction of the pipe provided, there is an advantage that the installation strength to the reinforcement of the inner surface member can be increased. However, in some cases, there is a difficulty in transport or manufacturing equipment if the inner surface member and the fitting member 2 are to be used continuously in the axial direction as the length of repair of the installed pipe becomes longer.

That is, the inner surface member and the fitting portion are usually taken out by winding a drum or a reel at the time of manufacture, and when the length exceeds a certain limit, the outer diameter of the drum or the reel after the winding is increased and installed on the manufacturing site. A problem arises. Moreover, when transporting these drums and rings, the transportation vehicle becomes large, and it becomes difficult to enter a lane of a normal road.

Even in such a case, the above-described embodiment of the present invention achieves the same operation and effect as in the case of using the inner surface member or the alignment member 2 continuous in the axial direction, and can solve the problem on the manufacturing facility or transportation as described above. The maintenance structure of the pipeline is provided.

That is, in the pipeline repair structure according to the present invention, the hollow frame-shaped reinforcement is disposed along the inner surface of the pipeline, and the plurality of inner surface members are continuously arranged in the axial direction and the circumferential direction of the pipeline installed inside the reinforcement. Installed and assembled in a tubular shape, the inner surface members adjacent to each other in the axial direction of the installed pipe line is connected to each other by the inner surface member connecting member disposed through both inner surface members, the inner surface member and the conduit The curable filler is filled with the inner surface.

Here, in the present invention, a plurality of fitting members are mounted in the axial direction and the circumferential direction of the pipe line provided inside the reinforcement, respectively, and the respective inner surface members are used using the respective fitting members 2. (3) to the reinforcing member (1), and the fitting members adjacent in the axial direction of the installed pipe are connected to the fitting member connecting member disposed through the two fitting members (2) in a state where the cross-sections of the connecting members are connected to each other. The structure connected to each other can be employ | adopted by this.

Moreover, in this invention, the said inner surface member connection member which connects the inner surface members adjacent in the axial direction of the installed pipeline is preferably employ | adopted the structure arrange | positioned so that it may cross | intersect in the axial direction of the pipeline provided adjacent to the circumferential direction. You can do it.

Furthermore, in the present invention, the connecting member 2 connecting member for connecting the fitting members 2 adjacent to each other in the axial direction of the installed pipe line is arranged so as to cross in the axial direction of the pipe line provided with adjacent ones in the circumferential direction. The structure can be made.

Further, in the present invention, a structure in which the positions of the inner member connecting member and the connecting member 2 connecting member are arranged so as to alternate with each other can be adopted.

In addition, in the present invention, cross-sections adjacent to each other in the axial direction of the inner surface member or the alignment member 2 are bonded to each other to adopt a structure integrated. Moreover, in this invention, it is preferable to employ | adopt the structure which interposed the sealing material between the said fitting member 2 and the inner surface member.

The present invention does not continuously install an inner surface member which is installed in a reinforcement provided in the inner side of an installed pipeline and is assembled in the form of a cylinder as a whole over the entire length of the repair length of the installed pipeline, as in the previous proposal, but in the axial direction of the installed pipeline. It is a state which divided | segmented into pieces and connected each other's cross section, and aims at achieving a desired objective by connecting them firmly.

That is, as one embodiment of the present invention, the connection strength is increased by dividing the inner surface member into a plurality of axial directions of the installed pipe line and connecting them to each other and connecting them to each other by the inner surface member connecting member disposed to overlap each other. When the curable filler is injected or the connection part is not deformed by external (water) pressure or internal (water) pressure, a reinforcing effect close to the performance equivalent to that of a single longitudinal continuum is obtained. Therefore, it is possible to use a constant longitudinal continuous part as the inner surface member, and as a result of the axial direction, manufacturing and transport problems are solved and handling is easy, and field workability is also improved.

In addition, the alignment member 2 is also divided into a plurality in the axial direction so that the cross sections are connected to each other, and at the same time, they are connected to each other by the coupling member 2 connecting members arranged to cover both of them. The reinforcing effect close to the performance equivalent to that of the case where the custom member 2 is used is achieved. In this way, manufacturing and transportation problems are solved and handling is easy, and workability in the field is improved.

Thus, as another embodiment of the present invention, the connecting position of the inner surface member is circumferentially shifted so that the connecting position in the axial direction of the inner surface member by the inner surface member connecting member is shifted in the axial direction with respect to those adjacent in the circumferential direction. Direction, and in this case, even if a tensile force is applied to the repair member in the axial direction, for example, by an earthquake or the like, if a gap occurs in the connecting portion of the inner surface member, the gap does not continue in the circumferential direction, so the circumferential direction of the pipeline It does not develop into a continuous gap in the furnace, and as a result there is an advantage that the curable filler is not easily broken.

In addition, as another embodiment of the present invention, as for the position connecting the alignment member 2 in the axial direction with the connection member 2, so as to deviate in the axial direction from those adjacent in the circumferential direction as described above. By arranging, even if a tension force is applied to the water retaining material in the axial direction and a gap is formed in the connecting portion, the gap does not develop continuously in the circumferential direction, and thus, the curable filler is difficult to be damaged.

Furthermore, by adopting a configuration in which the positions of the inner member connecting member and the fitting member 2 connecting member are alternated with each other according to another embodiment of the present invention, any one connecting member exists in the circumferential direction in the entire length of the pipeline. Since only the effect of this invention can be improved further, the curable filler can prevent it from leaking to the surface of an inner surface member at the time of injecting a curable filler. In addition, even after the formation of the repairing material, it is possible to prevent the fluid in the inner and outer surfaces of the installed conduit from flowing into or out of the inner surface member.

In addition, as another embodiment according to the present invention, the inner surface member and the fitting member 2, or a portion where the cross-sections are connected to each other in the axial direction with respect to the inner surface member or the fitting member 2, for example, an adhesive or a sealing member By adopting a structure in which the joints are integrally bonded to each other by a sealant or the like, the water-tightness and the bonding property can be ensured at the connecting portion in the inner surface member or the fitting portion, and the above-described effects can be increased.

Further, by interposing the sealing member between the fitting member 2 and the inner surface member, a watertight structure can be formed between the inner surface member and the fitting member 2, and in particular, the inner member connecting member and the fitting member 2 are connected. By using a configuration in which positions are shifted from each other, each inner surface member is fitted into the fitting member 2 through a continuous sealing material in the connecting portion of the inner surface member to further enhance the watertight structure in the connecting portion of the inner surface member. You can be sure.

The structure for injecting the end portion of a conduit for repair of the present invention is an end structure of the repair material for injecting ginseng water into a gap formed between the inner surface of the conduit provided and the repair material provided therein, and the inner surface of the repair material in the axial end portion thereof. Both ends of the tubular member made of a water-permeable material are pressed and fixed to the inner surface of the pipeline installed at a predetermined distance away from the axial direction by the corresponding hollow diameter expanding members, respectively, It will have the feature of providing the ash injection port in the vicinity of the end of the cylindrical member.

In the present invention, a hollow elasticity is formed between both ends of the tubular member and the inner surface of the conduit or the repairing member provided, or between both ends of the tubular member and the respective hollow diameter expanding members. It is preferable to employ the structure in which the member is fitted.

In addition, in the present invention, the above-described injection structure is provided on one side of the repairing material, and on the other end, a cylindrical member made of a water-permeable material on the inner surface of the other end and the inner side of the pipeline provided only a predetermined distance away from the position in the axial direction. It is possible to preferably employ a structure in which both ends of the end portion are pressed and fixed by the corresponding diameter expanding member in the form of a hollow.

Furthermore, in the present invention, it is preferable to adopt a structure in which a hollow elastic member is sandwiched between both ends of the cylindrical member provided on the other end side of the water retaining member and the hollow diameter-expanding member.

The present invention provides a hollow form of both ends of a cylindrical member made of a water-permeable material, while not sealing both ends of a cylindrical gap formed between the installed pipe and the repair member with a hardenable material such as mortar. It is intended to achieve the desired purpose by packing by pressing and fixing on the inner surface of the pipeline and the inner end of the repair material provided by the diameter expanding member.

That is, in the present invention, a sail cloth made of, for example, woven cloth such as a woven fabric, is provided on the inner surface of an axial end of the repair material and an inner side of the pipe provided at a distance apart from the position in the axial direction. Both ends of the tubular member made of a water-permeable material, such as), are crimped and fixed using a hollow diameter expansion member, respectively, and the ends of the tubular gap formed between the installed pipe and the repair member are sealed, Ash is injected into the cylindrical gap through the injection hole provided in the inner surface of the repair material or the cylindrical member.

Therefore, there is no need to wait until it is cured as in the case of sealing with a curable material such as mortar, and after starting sealing with the cylindrical member, it is possible to start injecting sage water immediately, and whether there is any flowing water. It becomes possible to seal stably, without being influenced by the state of the inner surface of an installed pipe, such as the like.

In addition, the hollow diameter expansion member ensures compression of both ends of the cylindrical member against the inner surface of the tubular member and the inner surface of the end of the water-retaining member by the hollow diameter expansion member, so that the ash extract does not leak from the seal even if the injection pressure of the ash is increased. It is possible to increase the pressure, so that the required time can be shortened.

Furthermore, by using a cylindrical member made of a water-permeable material as the sealing member, excess water and invasive water from the outside can be discharged during injection of ash and water through this sealing portion, and bubbles can be prevented from being formed. In addition, it is possible to improve the quality of raw ash after construction.

In the present invention, the both ends of the tubular member are not compressed only to the inner surface of the conduit and the end portion of the water retaining member provided by the hollow diameter expanding member. Even if there are irregularities on the inner surface of the conduit and the end of the repairing material, the inner surface of the conduit can be deformed in response to the inner surface of the tubular member, and the sealing property can be firmly secured to the crimp fixed part of the tubular member. It is possible to increase the pressure.

In addition, as another embodiment according to the present invention, while providing the above-described injection structure of the present invention on one end of the repair material, the other end of the cylindrical member made of a structure equivalent to those structures, that is, a water-permeable material By constructing a structure formed by pressing and fixing the inner surface of the water-retaining material by the hollow diameter-expanding member, respectively, with respect to the inner surface of the end portion of the water conduit and an installed pipe line which is only a predetermined distance away from the position, the ash is injected from the sealing portion on the other end side. It is possible to help the excess moisture and the invasive water to be discharged over the entire region length, and to prevent the formation of bubbles, which can greatly improve the quality of ash after injection.

Thus, also in the sealing structure on the other end side, the hollow member is interposed between the outer circumference or the inner circumference of both ends of the tubular member, thereby crimping the tubular member against the inner surface of the conduit provided by the hollow diameter expanding member and the inner surface of the end of the repair member. The sealing property at the fixed part can be easily improved, and workability can be improved and ash injection pressure can be increased.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited to these drawings.

First, in order to cope with the quantity of contaminated water in sewage pipelines to be repaired, an environment in which people can work in the pipelines by appropriate methods is created. For example, a water plug is installed on the upstream side of the maintenance target pipe to prevent inflow of contaminated water.

Subsequently, a cross section (hereinafter referred to as a cross sectional view in this direction) cut along the radial direction of the conduit provided in FIG. 1 is a cross section cut along the axial direction of a conduit provided in FIG. 2 in the same manner (hereinafter, A plurality of ring-shaped reinforcing members 11 divided into a plurality of ring-shaped reinforcing members 11 and connected to each other at regular intervals in the axial direction of the pipe P provided. Two connecting members 12 are loaded into a manhole (M1 and M2 in FIG. 29) and the like to assemble a reinforcement body 1 in the form of a hollow frame.

In this case, the ring-shaped reinforcement member 11 and the connection member 12 of the size which can be carried in the previously installed pipe P may be assembled on the ground. The outer shape of this reinforcement body 1 is a shape which substantially conforms to the inner surface shape of the installed pipe P. In the case of the installed pipe P which has a circular cross section like this embodiment, the outer shape of the reinforcement body 1 becomes cylindrical. . Moreover, the outer diameter dimension of the reinforcement body 1 is a diameter slightly smaller than the inner diameter dimension of the installed pipe P in consideration of the level | step difference, bending, etc. of the installed pipe P. As shown in FIG.

The ring-shaped reinforcing member 11 is formed in a ring shape along the inner surface of the pipe P which is installed as a whole by combining the three bow-shaped segments 11a, 11b and 11c with each other as the coupling member 11d in this embodiment. It is assembled, and the material may be a high rigid material such as steel, and may be surface treated to improve durability. Also, the end portions of the bow-shaped segments 11a, 11b, 11c can be directly overlapped and joined without using the engaging member 11d.

In addition, on the inner circumference of each ring-shaped reinforcing member 11, a plurality of recesses 110 for fitting the fitting member 2 to be described later are formed on the circumference at equal intervals. In order to facilitate the flow in the axial direction of the tube P provided with the curable filler in the uncured state in the process of injecting the curable filler described later, irregularities 111 are repeatedly formed in the same shape in the circumferential direction. Each fitting recess 110 has a slightly wider central portion in the depth direction and a narrower opening portion. Furthermore, each of these ring-shaped reinforcing members 11 has through holes 112 penetrating in the axial direction at regular intervals in the circumferential direction.

The connecting member 12 is disposed between the ring-shaped reinforcing member 11 adjacent in the axial direction, and serves as a spacer 12a, bolts 12b having male threads at both ends thereof, respectively, It consists of a nut 12c clamped to the male screw of the bolt 12b, the bolt 12b is inserted into the pipe member 12a interposed between the adjacent ring-shaped reinforcing member 11, the male screw at both ends Are inserted into the through-holes 112 of the ring-shaped reinforcing member 11, respectively, and in this state, the nut 12c is screwed into each male screw, thereby through-hole 112 of each ring-shaped member 11 Since the number of the bolts 12b of the connecting member 12 is greater than the number of inserts, the plurality of through-holes 112 remain in each ring-shaped reinforcing member 11 even after assembly of the reinforcing body 1. It becomes

In addition, when the pipe P provided has bending, as shown in FIG. 3, the length of the pipe material 12a of the said location is different, and the adjacent ring-shaped reinforcement member 11 is shown in FIG. You can cope by connecting to the inverted eight. In addition, when the pipe P provided has a step | step, as shown in FIG. 4, the length of the pipe material 12a of the said location differs, and the adjacent ring-shaped reinforcement member 11 is shown in FIG. It is possible to cope by providing a portion connecting to an eight-shaped shape as indicated by B in the same way as the portion connecting to the same inverted eight shape.

Subsequently, as shown in the cross-sectional view of Fig. 5, a plurality of fitting members 2 are provided in parallel with each other along the axial direction of the pipe P provided inside the reinforcing member 1 in the form of a hollow frame. Each of the fitting members 2 is a long member having the same cross section, and the length thereof is preferably, for example, a length between the manhole and the manhole of the installed conduit.

Installation of the fitting member 2 to the reinforcing body 1 is performed by fitting the fitting member 2 to each fitting recess 110 formed around the inner circumference of the ring-shaped reinforcing member 11. As shown in Fig. 6, the cross-sectional shape of the fitting member 2 is substantially similar in thickness, and its shape is a square C-shape that is almost the same as the fitting recess 110, so that the opening 21 is The opening 21 is fixed to the reinforcement 1 with the opening 21 facing inward of the reinforcement 1 so as to coincide with the opening portion of the fitting recess 110. The material of the fitting member 2 may be made of thermoplastic resin, thermosetting resin, or the like as the inner surface member 3 shown below.

Subsequently, as shown in the cross-sectional view shown in FIG. 7 and the longitudinal cross-sectional view shown in FIG. 8, the inner surface member 3 is provided inside the reinforcement 1 via each fitting member 2. In this embodiment, the inner surface member 3 may use a longitudinal continuum in the form of a plate along the axial direction of the installed pipe P, and the manhole and manhole of the pipe, for example, the length of which is provided as in the fitting member 2 above. The length between them may be sufficient. In addition, the cross-sectional shape is symmetrical as shown in the enlarged view of Fig. 9, and fitting convex portions 31a and 31b are integrally formed on both edges of one side thereof. .

As the material of the inner member 3, for example, polyethylene resin for sewer pipes, thermoplastic resins such as olefins, or thermosetting resins including unsaturated polyester resins, or fiber reinforced plastics such as GFRP, or metals including stainless steel may be used. Can be.

The distance between the fitting convex portions 31a and 31b of the inner surface member 3 is equal to the distance between the alignment members 2 installed in parallel with each other inside the reinforcement 1, and the inner surface members 3 adjacent to each other. In the state in which the fitting convex portion 31a of one of the inner surface members 3 and the fitting convex portion 31b of the other inner surface member 3 are in contact with each other, the openings 21 of the fitting member 2 respectively. ) Is inserted. Since the protruding ends of the fitting convex portions 31a and 31b in each of these insertion states are wider than the opening portion 21 of the fitting member 2, the inner surface member 3 is reinforced through the fitting member 2. It installs firmly with respect to the sieve 1, and will be in a state fixed.

The inner surface member 3 can be wound up, for example, in a reel, etc., is introduced into the reinforcement 1 in the pipe P provided through the manhole, and is preferably fitted into the fitting member 2. Further, in order to ensure the watertightness between the inner surface members 3 adjacent to each other, as shown in the enlarged sectional view of the main portion of FIG. 10, the front end face and the fitting member of the fitting convex portions 31a and 31b of each inner surface member 3 are aligned. It is preferable to interpose the sealing material 5, such as synthetic rubber and horizontal lubrication rubber, between (2).

Subsequently, as shown in the cross-sectional view of FIG. 11, the curable filler 4 is injected and cured between the provided pipe P and the inner surface member 3. As the curable filler 4, for example, cement-based materials such as cement milk, mortar, concrete, unsaturated polyester resins, epoxy resins, and the like can be used, and can be appropriately selected according to the required performance and cost. In order to inject the curable filler, the injection structure described later is suitable, but may be injected by installing the ash structure or the like at the end of the other provided tube, or may be injected in a batch manner by providing an injection hole in the inner surface member (3).

In the above embodiment, it is particularly noteworthy that a plurality of ring-shaped reinforcing members having high strength are connected and integrated in the axial direction of the pipe P provided by the connecting member 12 in the pipe P provided therein, so that the holes are drilled. A frame-shaped reinforcement 1 is provided, and the inner surface member 3 is supported by being fitted with the fitting member 2 with respect to the reinforcement 1, between the inner surface member 3 and the pipe P installed. Since the curable filler 4 is filled in, the tube of the reinforcing structure is built in the tube P provided, and the strength of the tube after repair becomes extremely high.

In addition, in the present invention, since the curable filler 4 is cured in a state where the curable filler 4 is inserted into the through hole 112 formed in the ring-shaped reinforcing member 11, the curable filler 4 and the reinforcement 1 have an anchor effect. As a result, the bonding strength of each other is greatly improved, and stable strength can be obtained.

In addition, even if the inner diameter of the installed pipe P is slightly larger or smaller than the predetermined dimension, it is possible to change the outer diameter of the ring-shaped reinforcing member 11 using the through hole 112. Furthermore, this through hole 112, together with the unevenness 111 formed around the outer circumference of the ring-shaped reinforcing member 11, reduces the injection resistance during the injection of the curable filler 4, and the reinforcement ( It is also effective in weight reduction of 1).

Furthermore, in the embodiment of the present invention described above, since the plate-shaped one that is continuous in the axial direction of the pipe P provided as the inner surface member 3 is used, the inner surface of the pipe after repair has no seam in the axial direction, As a result, the flow capacity can be improved.

Here, in the embodiment of the present invention described above, when the reinforcement body 1 may float during the injection process of the curable filler 4, as shown in the cross-sectional view of FIG. The puff member 6 may be attached. In addition, in order to prevent the reinforcement 1 from being deformed by an external pressure action, such a gap filling member 6 may be provided on the side of the reinforcement 1. In this way, the gap filling member 6 provided on the side is not deformed because the water retaining member 1 comes into contact with the pipe P installed at the time of the external pressure action. In addition, the gap filling member 6 can be mounted using a through hole 112 or the like of the ring-shaped reinforcing member 11.

Further, in the above embodiment, an example in which the inner member 3 is mounted to the reinforcement 1 using the fitting member 2 is disclosed, but the cross-sectional view in FIG. 13 (A) is enlarged in the main portion in FIG. 13 (B). As shown in the figure, a structure in which the inner surface member 3 is fitted with respect to the fitting recess 110 formed in the reinforcement 1 can also be adopted. In this case, it is preferable that the sealing material 5 for ensuring the watertightness between adjacent inner surface members 3 is interposed in the contact surface of inner surface members 3 comrades.

In the above embodiment, the present invention is applied to an installed pipeline having a circular cross section, but the present invention is equivalent to an installed pipeline having an arbitrary cross section such as a horseshoe tube or a spherical tube (box culvert). Can be applied.

14 is a cross-sectional view when the present invention is applied to a horseshoe tube. The embodiment of Fig. 14 uses the embodiment of the present invention shown in Figs. 1 to 11 almost as it is, and shows the shape of a bow segment constituting the ring-shaped reinforcing member 11 of the reinforcement 1, The inner surface of the release pipe P 'to be repaired as a whole is changed as appropriate by changing it appropriately to fit the shape of the pipe P' of another cross-sectional shape to be repaired, and joining each other with the coupling member 11d having the same shape as the previous embodiment. The present invention can be easily applied by manufacturing in the following form.

In addition, about the inner surface member used in this invention, in addition to arrange | positioning the long inner flat member form the inner surface member 3 along the axial direction of the pipe | tube P provided like the previous embodiment, in the longitudinal cross-sectional view shown in FIG. A cylindrical inner member 3 ＇is inserted into the reinforcement 1 along the inner surface of the pipe P installed as described above, or an inner surface member having a width suitable for the reinforcement 1 as shown in the longitudinal cross-sectional view of FIG. It is preferable to insert 3i) in the form of a spiral.

In the case of using a cylindrical inner surface member (3), the deformed shape in advance in a U shape is wound around a reel or the like, and then introduced into the reinforcement 1 through the manhole from the ground. In this case, as shown in Fig. 15, it is preferable in operation to divide the cylindrical inner surface member 3 'into appropriate lengths.

In the case of arranging the cylindrical inner surface member 3 'in the circumferential direction and using the inner surface member 3' arranged in the spiral form, as shown in Fig. 15 or 16, the reinforcement member The inner fitting recess 110 of (1) is provided in a circular or spiral form and fits the fitting convex portion 31 'or 31' formed on the inner surface member 3 'or 3'. In addition, even when such an inner surface member (3 'or 3') is used, it is preferable to interpose the sealing material 5 in the joint part of inner surface members.

Moreover, even when using any form of inner surface member, although it does not specifically limit about the formation position of the fitting recessed part of a reinforcement body, or the fitting convex part for fitting to a fitting member, According to the axial direction of the installed pipe P, The case where the inner member 3 of the shape is arranged will be described as an example. In addition to providing the fitting convex portions 31a and 31b at both edges as shown in FIG. As described above, the same symmetrical fitting convex portions 31a and 31b should be provided at both edges, and the convex fitting portion 31c having a shape in which they are integrated in the middle portion thereof is provided to the fitting convex portion 31c in the middle thereof. As a matter of course, modifications such as fitting the fitting member 2 or the fitting recess 110 of the reinforcement 1 alone are possible.

In each of the above embodiments, it is preferable to arrange the cylindrical outer surface member 7 along the inner circumferential surface of the installed pipe P, as shown in the cross-sectional view of FIG. 18 before assembling the reinforcement 1. . This outer surface material 7 prevents the curable filler 4 from escaping out of the line in which the curable filler 4 is installed, and also prevents the curable filler 4 from deteriorating in performance due to contact with the groundwater. The outer surface material 7 can be fixed with respect to the inner surface of the pipe P provided by a suitable fixing method, such as using a fiber sheet or a waterproof sheet, using nails, an adhesive agent, etc., for example. By using a water-permeable material such as a fibrous sheet as the outer material 7 and using a cementitious material as the curable filler 4, the excess moisture and air contained in the curable filler 4 are passed through the outer material 7. Can be discharged to the outside. Therefore, since the cementitious material can be kept in a dense state, it can be maintained in a state that is hard to be affected by the groundwater even before complete curing, and can reliably exhibit high strength after curing.

19 is a cross-sectional view showing a structure before filling a curable filler as a structural explanatory diagram of an embodiment according to the present invention. Referring to Fig. 19, the pipe P provided is cut in the vertical plane along the cylinder axis direction, and the upper part is cut and shown in the same vertical plane in the maintenance structure. 20 is a sectional view taken along line AA in FIG. 19, and FIG. 21 is an enlarged view of portion B in FIG.

A hollow frame-shaped reinforcement 1 is disposed in the installed pipe P, and an inner surface member 3 is mounted therein by using a fitting member 2 therein, and a tubular shape is formed along the pipe P installed overall by them. The repair material is formed.

Inside the reinforcement body 1 of a hollow frame shape, it is mounted in parallel with each other along the axial direction of the pipe P in which the several fitting member 2 was provided. As shown in a perspective view of a state in which one end is inserted into a mating member connecting member 40 described later with reference to FIG. 22, the mating member 2 is a fitting recessed portion of the ring-shaped reinforcing member 11 described above. It is a molded article having the same shape as a C-shape extending at about the same angle as 110), and its length is, for example, to have a constant length of about 5 m.

In Fig. 22, the opening portion indicated by 21 is inserted into each of the plurality of fitting recesses 110 for the divided ring-shaped reinforcing members provided in the axial direction so as to face inward.

The fitting member 2 having a constant length as described above can cover the entire length to be repaired by allowing a plurality of pieces to be connected in the axial direction of the pipe P provided. That is, the plurality of fitting members 2 are connected to the fitting member connecting member 40 by connecting the cross-sections adjacent in the axial direction to each other, so that the entire length thereof corresponds to the repair length of the pipe P provided with the reinforcement 1 ) Is mounted.

The fitting member coupling member 40 is a member of the same shape having a C-shaped cross section at an angle to which the fitting member 2 can be fitted, as shown in FIG. Molded articles of resin and molded articles of thermosetting resin (including FRP) are available, and particularly those having high strength are preferably used as preferred embodiments of the present invention.

One end of the fitting member connecting member 2 is inserted into the fitting member connecting member 40 up to about half of the length of the connecting member 40, and the remaining half of the fitting member connecting member 40 is one end of the other fitting member 2. By inserting the cross-sections of the two fitting members 2 are joined to each other and connected. Thus, it is preferable to make a complete water film structure by using an adhesive agent, a sealing material, or integrating each other by the method of fusion | melting etc. to the part connected to each other in this way.

Thus, the inner surface member 3 is connected to the plurality of fitting members 2 which are connected in the axial direction of the pipe P installed by the fitting member connecting member 40 at regular intervals in the circumferential direction inside the reinforcement 1 as described above. ) Is installed. As shown in a perspective view, the inner surface member 3 is a state in which one end is inserted into the inner surface member connecting member 50, which will be described later with reference to FIG. It has a cross-sectional shape in which the fitting convex parts 31a and 31b which protrude to one side were integrally formed in the both edges of the main-body part of flat plate form.

The distance between the fitting convex portions 31a and 31b is equal to the distance between the fitting members 2 mounted parallel to each other inside the reinforcing body 1, and on one side of the inner surface members 3 adjacent to each other. The fitting convex portion 31a and the fitting convex portion 31b of the other inner surface member 3 are inserted into the openings 21 of the respective fitting members 2 in contact with each other.

In such an insertion state, since the width of the tip protrusion of each fitting convex portion 31a, 31b is wider than the width of the opening portion 21 of the fitting member 2, the inner surface member 3 is a fitting member ( Through 2) is formed in a state that is firmly coupled to the reinforcement (1).

Thus, a plurality of inner surface members 3 having a constant length as described above are connected to each other in the axial direction of the pipe P provided in the same shape as the above-described fitting member 2, thereby affording a repair length. That is, the plurality of inner surface members 3 are connected to each other by the inner surface member connecting member 50 in a state in which the adjacent sections in the axial direction are coupled to each other, so that the entire length thereof corresponds to the length of the repair of the installed pipe P. The whole is mounted to the fitting member 2 joined by the fitting member connecting member 40 in one.

As shown in Fig. 23, the inner surface member connecting member 50 is the same cross-sectional member having a U-shaped cross section, and has a shape that is pushed into the inner surface member 3. In addition, as the material, a processed product of a metal material, a molded article of a thermoplastic resin, a molded article of a thermosetting resin (including FRP), and the like can be employed. As a preferred embodiment of the present invention, a particularly high one is preferably used.

To connect the two inner surface members 3 in the longitudinal direction using this inner member connection member 50, the inner member connection member 50 is formed on the inner side of one end of the one piece of inner member 3 almost at its length. After inserting it to half, the other half is made to protrude, and one end of another inner surface member 3 adjacent to the remaining portion is inserted so that the end surfaces of both inner surface members 3 are brought into contact with each other. . It is preferable to form a complete water film structure by using an adhesive agent, a sealing material, or integrating them with each other in the connecting portions of the end faces in the same manner as the above-described fitting member 2.

In the following, specific embodiments of the method for laying each of the above members into the installed pipe P will be described in detail.

First, an environment in which a person can work in the pipe P installed by an appropriate method such as installing a plug of water plug on the upstream side of the pipe P installed on the basis of construction is provided. The reinforcing body 1 is to carry the partially assembled assembly into the installed pipe P such that the size of the bow-shaped segments 11a, 11b, 11c or the connecting member 12 can be carried into the pipe P installed through a manhole or the like. It is preferable to improve workability.

For example, instead of joining the bow-shaped segments 11a, 11b, 11c, which are divided into three circumferences in the circumferential direction, the partial reinforcement connected only three in the axial direction by the connecting member 12 into the installed pipe P. Partial reinforcement is installed at a position where it is carried in sequentially and becomes a starting point, for example, at one end of the installed pipe P or the bent portion of the installed pipe P, and connected in the circumferential direction and the axial direction to form a tubular reinforcement as a whole (1) Can be obtained.

After the assembly of the reinforcing body 1 is completed, the fitting member 2 is fitted into each of the fitting recesses 110 inside the reinforcing body 1. This state is shown in sectional drawing of FIG. 24, and the enlarged view of A part is shown in FIG. Subsequently, the inner surface member 3 is inserted into the fitting member 2. These fitting members 2 and the inner surface member 3 are connected by the fitting member connecting member 40 and the inner member connecting member 50 by the above-mentioned method, respectively, and act as one continuous body in the axial direction.

Further, in order to increase the watertightness between the inner surface members 3 adjacent to each other in the circumferential direction, as shown in FIG. 25, the fitting convex portions 31a and 31b of each of the fitting members 2 and the respective inner surface members 3 fitted therein. It is preferable to interpose a sealing material 5 such as synthetic rubber, water-expandable rubber, or the like between the distal end of the < RTI ID = 0.0 > Further, as shown in Fig. 21, the sealing member 5 may be interposed between the side surfaces of the fitting convex portions 31a and 31b of the respective inner surface members 3.

Here, the mounting of the inner surface member 3 is preferably considered so that the inner surface member connecting member 50 is not aligned in a line in the circumferential direction. That is, as shown in Fig. 19, the connection position of the inner surface member 3 by the inner surface member connecting member 50 is set to be offset from each other in the axial direction with respect to the pair adjacent to the circumferential surface.

By arranging in this way, even if a gap is generated in the connecting portion of the inner surface member 3 when a tension force is applied to the inner surface member 3 in the barrel axial direction of the pipe P provided by an earthquake or the like, the interval is the circumference of the installed pipe P. It is stable as a structure because it does not develop continuously along the direction.

In addition, as shown in FIG. 19, it is preferable to take care that the fitting member connecting member 40 does not align side by side in the circumferential direction even when the fitting member 2 is mounted. By arranging the connection positions alternately in the barrel axial direction with respect to the pair adjacent to the circumferential direction, a tension force acts in the barrel axial direction of the pipe P installed in the fitting member 2 due to some cause such as an earthquake and the like. Even if a gap is generated at the connecting portion of the c), the gap does not continuously develop in the circumferential direction of the pipe P provided, so that the gap is stable as a structure.

Furthermore, as shown in Fig. 19, the positions of the fitting member connecting member 40 and the inner member connecting member 50 are staggered from each other, thereby doubling the above effects, and as described later, the pipe P provided with the inner member 3 is installed. When injecting a curable filler between and, the curable filler can be prevented from leaking to the surface of the inner surface member. In addition, it is possible to prevent the fluid from flowing into or out of the inner surface member 3 from the inner surface or the outer surface of the pipe P provided after the completion of the construction of the repairing material.

Such an effect is provided with a sealing material 5 interposed between the front end portions of the fitting convex portions 31a and 31b of the inner surface member and the alignment member 2, or at the connection portion of the inner surface member 2 and the alignment member 3 with each other. By employ | adopting the structure which integrated the cross section which contacted with the adhesive etc., it can further increase. Thus, in the embodiment shown in Figs. 19 and 20, the curable filler can be injected between the inner surface member 3 and the tube P provided to be filled and cured therebetween.

Here, the cross-sectional shape of the fitting member 2 used in the present invention is not limited to the angled C-shape as disclosed in the above embodiment, and the outer surface shape can be connected to the reinforcing body 1, and the inner surface can be connected. The shape may be applied to any shape as long as the inner member 3 is inserted into the inner surface member 3. In addition, the shape of the fitting member connecting member 40 is also not limited to the shape employed in the above embodiment, and is not limited to being mounted only on the outer surface of the fitting member 2, but may be mounted on the inner surface.

The opposite end of the cylindrical member 200 is located outwardly by a predetermined distance in the axial direction from one end of the water retaining member 100, and is similarly fixed to the inner surface of the pipe P provided along the circumferential direction.

The compression fixing structure will be described in detail. The hollow elastic members 300a and 300b are disposed on the inner surface of the end portion of the water retaining member 100 and the inner surface of the pipe P, respectively, and the inner surfaces of the elastic members 300a and 300b respectively. Both ends of the cylindrical member 200 are disposed in the circumferential direction, and hollow diameter expanding members 400a and 400b are disposed inward along both ends of the cylindrical member 200 in the circumferential direction of the inner surfaces of the elastic members 300a and 300b.

Is pressed against the inner surface of the

The material of the tubular member 200 can be used to sew a cloth fabric made of cloth such as woven fabric (woven fabric), one end side corresponds to the inner circumference of the repair material 100, the other end side of the installed pipe P Each of the inner circumferences can be sewn correspondingly. In addition, the tubular member 200 should be used a canvas or sewing method having a strength that can withstand the injection pressure during injection of the ash ginseng (灰 三 物).

In addition, a single bubble sponge rubber or the like is used as the hollow elastic members (300a, 300b), the hollow elastic members (300a, 300b) is a temporary use that is removed after the ash and the injection is cured. Therefore, there is no particular restriction, and materials such as rubber or urethane, such as CR, are suitable.

The hardness of Shore A25 is appropriate, and the flexibility of adapting to the irregularities of the inner surface of the repair material 100 or the inner surface of the installed pipe P and the compression by the hollow-shaped diameter expanding members 400a and 400b are used. It is preferable to serve both as a strength which is not deformed by the injection pressure.

As a manufacturing method of this hollow elastic member 300a, 300b, the edge parts of a block-shaped member are combined with an adhesive agent etc., and the outer surface shape is matched with the inner surface shape of the installed pipe P and the water holding material 100. As shown in FIG. If the cross-sectional shape of the provided pipe P is circular as in the present embodiment, a ring-shaped shape is taken, and if a horseshoe type, a horseshoe shape is used, a hollow elastic member is manufactured in a shape that matches the cross-sectional shape of the pipe line. The thickness in the radial direction is preferably about 10 mm because a suitable compression zone can be obtained. On the other hand, the diameter and width can be adjusted according to the work site.

The hollow diameter expanding members 400a and 400b have the same structure, and a plurality of divided steel rings 410 and 410b and a plurality of jacks 420a and 420b are used. Referring to Fig. 28, the outer hollow diameter-expanding member 400b will be described by way of example. Each of the divided pieces 411b forming the steel ring 410b slides in the circumferential direction with those adjacent to each other. And are connected to each other by a jack 420b.

The inner hollow diameter expanding member 400a is configured in the same manner. In this embodiment, each hollow diameter expanding member 400a, 400b is provided in parallel with each other in the axial direction of the pipe P in which two pairs of steel rings 410a, 410a or 410b, 410b are installed, respectively, The split pieces (411a and 411a comrades, or 411b and 411b comrades) which face each other are fixed to each other by a connecting member F such as the back.

Thus, each of the jacks 420a and 420b is mounted to the connecting member F through coupling members C provided at both ends, and two iron rings 410a, 410a or 410b and 410b are operated by operating the jacks 420a and 420b. ) Diameter is enlarged.

As such, each hollow diameter expanding member 400a and 400b is formed by using two steel rings 410a, 410a to 410b, and 410b, respectively, so as to prevent the slant from being inclined at an angle in the course of installation in the pipeline. Can be easily installed.

However, even if each of the hollow diameter expanding members 400a and 400b is constituted by a pair of steel rings 410a and 410b, the same effect as that of the present embodiment can be achieved by installing them vertically in the pipeline. have.

Here, the contour shape of the hollow diameter expanding members 400a and 400b is similar to the hollow elastic members 300a and 300b, and when applied to a circular cross-section as in the present embodiment, it is a ring shape or a horseshoe. In the case of application to a pipe of a die, it may be a shape conforming to the shape of the pipe P provided as in the case of a horseshoe.

Here, the hollow diameter expanding member (400a, 400b) is not limited to the above structure, for example, by injecting air into the inside of the air inflating bag such as a tire tube to the diameter of the cylindrical member 200 You can also zoom in.

Thus, the cylindrical member 200 is provided with an injection port 500 for a plurality of ash ginseng. This ash water injection port 500 may be comprised by arbitrary components which can be connected with the front-end | tip of a ash water injection hose (not shown), and the material may be any of a metal or a resin material.

As shown in FIG. 27 as a structure for mounting such a lime water injection port 500 to the cylindrical member 200, as the ash water injection port 500, a hose can be connected to one end of the flange 500a via a pipe connection joint. The long sleeve 500b is formed so that the male screw is engraved, and the third injection hole 500 of the structure having the short sleeve 500d engraved with the female screw that the nut 500c is screwed on the other end may be used.

On the other hand, the tubular member 200 is drilled into the short sleeve 500d of the ash injection hole 500 so as to insert the short sleeve 500d along the surface of the tubular member 200 by inserting the short sleeve 500d into the hole. By screwing the nut 500c, the cylindrical member 200 is clamped between the nut 500c and the flange portion 500a.

Moreover, it is also preferable that the periphery of the hole of the tubular member 200 is hardened with an adhesive so as not to loosen the thread, or the hole is opened with a forceps to fuse the thread.

Hereinafter, the method of constructing the above-mentioned end structure is explained in full detail. The tubular member 200 and the hollow elastic members 300a and 300b and the hollow diameter expanding members 400a and 400b for constructing the end structure are hypothesized through the manhole M1 shown in FIG. It is brought into the tube P. However, first, the hollow elastic member 300a is disposed on the inner surface of the end portion of the water retaining material 100, and the hollow elastic member 300b is disposed on the inner surface of the pipe P provided at a predetermined distance in the axial direction therefrom. do.

At this time, it is preferable to temporarily fix each hollow elastic member 300a, 300b with an adhesive tape or the like. Subsequently, a cylindrical member 200a made of a water-permeable material is disposed so that one end slightly protrudes inward over the inner hollow elastic member 300a, and the other end is outward from the outer hollow elastic member 300b. Place it to protrude. Also at this time, it is preferable in operation that both ends of the cylindrical member 200 are temporarily fixed with an adhesive tape or the like along the inner circumferential surfaces of the hollow elastic members 300a and 300b. The tubular member 200 is equipped with a plurality of ash water injection ports 500 in advance.

Thereafter, the inner hollow diameter-expanding member 400a is assembled into one end of the cylindrical member 200, and the jack 420a is operated to enlarge the diameter of the hollow-shaped diameter expanding member 400a. By compressively deforming the elastic member 300a, one end of the tubular member 200 is press-fixed to the inner surface of the water retaining material 100. Subsequently, the outer hollow diameter expanding member 400b is assembled to the inside of the opposite end of the cylindrical member 200, and the jack 420b is operated to enlarge the diameter thereof so that the hollow elastic member has a hollow shape through the cylindrical member 200. By compressing and deforming the member 300b, the other end of the tubular member 200 is press-fixed to the inner surface of the installed pipe P to finally obtain the end structure shown in FIG.

Further, it is preferable that the other end of the pipe P provided by E2 in FIG. 29 is the same structure as the above-described end structure, but only the ash water injection port 500 is sealed by the end structure of the omitted form. By connecting the hose to the ginseng inlet 500 in the sealed state can be carried out the injection operation of the ginseng. At this time, unlike the conventional method of sealing each end portion with a curable material such as mortar, it is not necessary to additionally have a curing process of the encapsulant, and the advantage of starting the injection of the ashes immediately after construction of the end structure is advantageous. have. Moreover, even if water flows in the inner surface of the installed pipe P, since it can reliably seal, since the tubular member 200 made from the water permeable material is used for the sealing part, the tubular member ( 200) through the air or excess moisture to be discharged to the outside so that the quality of the ash after curing is stable and the reliability is improved. In addition, since the diameter of the hollow diameter expanding members 400a and 400b of the end portion of the repair member 100 is enlarged, both ends of the tubular member 200 are disposed on the inner surface of the installed pipe P and the inner surface of the repair member 100. Since it is surely crimped and fixed, the injection pressure of the lime ginseng can be raised significantly compared with the case of sealing the both ends of a pipe by sealing with a mortar etc., and work efficiency can be improved.

Further, after the ash is cured, each of the hollow diameter expanding members 400a and 400b, the hollow elastic members 300a and 300b, and the cylindrical member 200 are removed. In order to improve the workability at the time of removal, when the release material is coated and coated in advance in contact with the ginseng, it can be easily removed because it is prevented from being integrated with the ginseng.

Here, in the above-described embodiment, an embodiment in which the hollow-shaped elastic members 300a and 300b are disposed outside the tubular member 200 and at the same time the lime water inlet 500 is provided in the tubular member 200 is disclosed. However, in the present invention, each hollow elastic member (300a, 300b) may be disposed on the inner surface of the cylindrical member 200, the ash water injection port 500 may be provided in the water holding material (100). 30 and 31 show cross-sectional views of the embodiment.

30 shows a hollow elastic member 300b disposed on an inner surface side at an end of a cylindrical member 200 which is pressed and fixed to an inner surface of an installed pipe P, and a hollow diameter expanding member 400b therein. By arranging the diameter of the hollow diameter expanding member 400b, the tubular member 200 is crimped and fixed to the inner surface of the pipe P provided through the hollow elastic member 300b.

Furthermore, referring to Figure 30, the end of the cylindrical member 200 of the side that is press-fixed to the inner surface of the water retaining material 100, as in the above-described embodiment, arranged a hollow elastic member 300a on the outer surface side Thus, the hollow diameter expanding member 400a is disposed on the inner side of the tubular member 200.

In the embodiment disclosed in Fig. 31, the hollow elastic members 300a and 300b are disposed on the inner surface of the cylindrical member 200, and the hollow shape is expanded by the hollow diameter expanding members 400a and 400b provided therein. Both ends of the cylindrical member 200 through the elastic members (300a, 300b) of the pressing member is fixed to the inner surface of the water-retaining material 100 or the inner surface of the pipe P provided.

In addition, as in the embodiment shown in FIGS. 30 and 31, the ash water injection port 500 is provided in the water retaining material 100 near the end of the cylindrical member 2. As described above, the mounting of the lime water injection port 500 to the water retaining material 100 may adopt a structure equivalent to that of the cylindrical member 200 according to the above-described embodiment. A pipe or the like having a male screw at one end may be screwed into place.

By the way, as shown in the embodiment of Figs. 30 and 31 described above, the hollow-shaped elastic member 300b is disposed on the inner surface of the tubular member 200 at a portion for crimping and fixing the tubular member 200 to the installed pipe P. , The structure sealing the end portion in a state in which the outer surface of the tubular member 200 is in close contact with the pipe P directly installed, it is possible to discharge the air accumulated in the upper part of the tubular member 200 through the tubular member 200 made of a water-permeable material. It is desirable in that it can be completely filled into the conduit.

In addition, in the above-described embodiment shown in Figs. 26 to 28, air may accumulate as much as the thickness of the hollow elastic member 300b. Therefore, when the pipe P provided is inclined, It is preferable to consider that the air can be discharged upward at the time of injection of the raw ginseng by providing at the lower end.

In addition, when the ash ginseng inlet 500 is provided at the end of the water repellent material 100 as in the embodiment shown in FIGS. 30 and 31, excess moisture from the air or the ginseng can be easily discharged from the tubular member 200 made of a water-permeable material. It is more preferable because it is.

Furthermore, in each of the above-described embodiments, the hollow-shaped elastic members 300a and 300b are interposed between the inner end portions of the water-retaining materials 100 at both ends of the tubular member 200 and the crimp-fixed portions to the inner surfaces of the pipes P provided. Although the embodiment of absorbing the irregularities of the inner surface of the installed pipe P or the inner surface of the water-retaining material 100 is easily and surely sealed, when the unevenness is not excessively present in each of the inner surfaces thereof, the hollow-shaped elastic member 300a, It is not necessary to provide 300b), and the use thereof can be appropriately selected according to the state of the unevenness of the inner surface.

As described above, according to the present invention, a hollow frame reinforcement body is assembled into a conduit provided, and the inner surface member is installed between the inner surface member and the inner tube member in a state of being installed by a method such as fitting an inner surface member to the reinforcement body. By filling the curable filler in the shape, the shape and dimensions of the reinforcing member constituting the reinforcing body can be appropriately changed in accordance with the situation such as the shape and the strength of the installed pipeline, and a reinforcing body having sufficient strength against damage or the like can be constructed.

Therefore, even in the case of repairing an old pipeline whose strength cannot be expected in an installed pipeline that has undergone deterioration, or even in the case of a large diameter pipeline such as a tunnel, the pipeline after repair can have high strength.

In addition, since the strength of the reinforcing body can be sufficiently high, it is possible to select a cheap material having good fluidity for the curable filler, and it is possible to realize good workability and low cost. In this case, even if there is a step or bend in the middle of the installed pipe line, it is easy to cope with it, and also a reinforcement body can be assembled to a cross-sectional shape even for a deformed pipe such as a horseshoe pipe line or a box calvert pipe line, thereby ensuring good constructability. Remuneration can be done.

In addition, since the material of the inner surface member is a thermoplastic resin molded product, it can be easily deformed and inserted in the bent portion or step portion of the pipeline or the arrangement of the reinforcement in the release tube, so that the inner surface of the pipeline after repair can be smoothly flowed. have.

In addition, in the present invention, since the inner surface member is held in a state of being supported by being inserted into the reinforcement body, external water pressure or the like does not directly act into the inner surface member, and there is no fear of deformation of the inner surface member, and even when the curable filler is injected. It can withstand the injection pressure and does not require additional measures such as assembling support reinforcing members separately as in the prior art, and can shorten the air.                 

Thus, by placing the inner member in the axial direction of the installed pipeline, for example, by using a longitudinal continuum having a length between the manhole and the manhole, the inner surface member (surface) of the repair member can be seamlessly arranged in the down direction, so that the inner member is arranged in a spiral manner. Compared with the prior art, the falling performance can be significantly improved.

Further, according to the present invention, the inner member is connected to the reinforcement by connecting the plurality of inner surface members in the axial direction of the installed pipe line by the inner member, and at the same time, the end portions of adjacent inner surface members are connected to each other at the connecting portion of the inner member. Since the inner member is connected to each other using the inner member connected to cover the inner member, the strength of the inner member is improved, and the connection part is deformed by the injection of the curable filler and external or hydraulic pressure. There is no concern, and almost the same performance as in the case of using one longitudinal inner surface member covering the entire length of the repair length of the installed pipeline can be obtained. In addition, the manufacturing and transport problems due to the longitudinal direction of the inner surface member is solved, as well as easy to handle it can be expected to improve the field workability.

Further, in installing the inner member to the reinforcement through the fitting member, the fitting member is also connected to the reinforcement by connecting the plurality of fitting members in the axial direction of the installed pipeline by the fitting member connecting member to the reinforcement member. If the part adopts a configuration in which the end faces of adjacent fitting members are in contact with each other and connects them using the fitting member connecting members arranged through the two fitting members, the strength of the connecting portion of the fitting member is improved, It is possible to obtain almost the same performance as using only one longitudinal alignment member over the entire length to be repaired, and to solve the manufacturing and transportation problems caused by the orientation of the alignment member. Improvement in field workability can be achieved.

In addition, by adopting a configuration in which the connecting position of the inner member by the inner member connecting member or the connecting member of the fitting member by the fitting member connecting member is spaced apart from each other in the circumferential direction by the axial direction, the inner member is aligned with the inner member by earthquake or the like. Even if a force is applied to the member in the axial direction and a gap occurs in the connecting portion, the gap does not continue in the circumferential direction, so that breakage of the curable filler can be suppressed.

Furthermore, by adopting a configuration in which the connection position of the inner member by the inner member is connected to the position of the fitting member by the fitting member, the effect of the present invention can be further increased, and the injection of the curable filler can be further improved. It is possible to effectively prevent the curable filler from seeping out of the surface of the inner surface member, and to prevent the fluid from flowing into or out of the inner surface member on the inner and outer surfaces of the conduit installed even after the completion of the formation of the repairing material.

In addition, by integrating the end faces of the inner surface members adjacent in the axial direction or the end faces of the fitting members adjacent in the axial direction by using an adhesive or a sealing material or by fusion, the watertightness and the bonding property in these connecting portions are ensured. By doing so, the effect of the present invention can be further increased.

Moreover, by interposing a sealing member between the fitting member and the inner surface member, a watertight structure can be formed between the inner surface member and the fitting member, and in particular, a configuration in which the positions of the inner member coupling member and the fitting member coupling member are slidably arranged to each other. By using together, the watertight structure can be further improved at the connection portion of the inner surface member such that each inner surface member is fitted to the fitting member through a sealing material continuous to the connection portion of the inner surface member.

Furthermore, according to the structure for injecting the end of the water retaining material according to the present invention, both ends of the cylindrical member made of a water-permeable material are respectively formed on the inner surface of the end of the water retaining material and the inner surface of the conduit provided by a predetermined distance in the axial direction from the position thereof. It is fixed and pressed inwardly by the diameter expanding member, and by providing ash injection port in the tubular member or the water retaining material in the vicinity thereof, it is used as a conventional curable material such as mortar in injecting ginseng water into the gap between the installed pipe and the water holding material. Unlike the case of sealing between the end of the repair material and the installed pipeline, it is possible to immediately start the injection of ash and ginseng without waiting for the hardening of the sealing material, and it is affected by the internal condition of the pipeline where the running water is installed. Compared with the related art, it can be greatly improved and the working efficiency can be improved. Moreover, since the tubular member used for the sealing site uses a water-permeable material, air or excess moisture may be discharged to the outside during injection of the ash, and the quality of the ash after curing is also improved.

In addition, since the both ends of the cylindrical member are pressed and fixed to the inner surface of the conduit or the repairing material installed with the hollow elastic member interposed therebetween, the sealing can be easily ensured even if the inner surface of the conduit or the repairing material is uneven. It is also possible to increase the injection pressure of ash.

Furthermore, by constructing the end structure of the present invention on one end of the repair material and the structure of the end structure of the present invention on the other end except for the ash injection port, both ends of the injection space of the ash extract can be reliably performed and the injection space Air can accumulate over the entire length of, or excess water or infiltration water from inside and outside the pipeline can be discharged, thereby achieving a significant quality improvement of the injected ash.
