Description

The present invention relates to a pipe lining construction apparatus and construction method for constructing a lining layer on the inner surface of an existing pipe such as a sewer pipe, a water pipe, and a gas pipe. The present invention relates to a pipe lining construction apparatus and construction method for carrying out a lining construction in which a tubular body formed by spirally winding a band-shaped member made of a plate-like body, so-called a lining pipe, is inserted into the pipe collar.
In particular, the present invention relates to a lining construction apparatus suitable for a small diameter pipe rod and a construction method thereof.

In a pipe rod, using a pipe making device that self-propells by rotation, a long strip member that is continuously supplied with joints formed on both side edges is spirally wound around the forming frame of the pipe making device. A lining for rotating and engaging adjacent joints to form a tubular body, leaving the tubular body, and additionally forming a tubular body with a belt-like member supplied in front of the already formed tubular body Construction techniques have already been proposed and are publicly known.
That is, the technique disclosed in Japanese Patent Application Laid-Open No. 8-261363 makes the forming frame bendable and is not limited to a circular cross-section tube rod, and is also applied to a rectangular cross-section tube rod, and an elastic lining. The tube can be formed as close as possible to the cross section of the tube rod. However, in this prior art, it is difficult to maintain the close contact state of the molded lining tube, and the diameter of the lining tube is somewhat reduced, so that a cross-sectional loss is inevitable.
Japanese Patent Application Laid-Open No. 2003-33969 uses a molded frame that is bent and bendable and attaches a joining mechanism portion that is hydraulically driven to the molding frame, and the folding portion of the attachment mechanism portion is bent. A lining construction device is disclosed in which the restriction is released and the injection pipe for the consolidated material is arranged side by side with the joining mechanism. Thus, a lining pipe is formed while folding the lining pipe in the joining mechanism portion inward, and at the same time, a consolidation material is injected from an injection pipe of the consolidation material arranged side by side in the joining mechanism portion, The lining pipe that has passed the part is restored to the outside with its elasticity, and as a result, the lining pipe is formed as much as possible in the cross-section of the tube so that no cross-section loss occurs and at the same time the filled consolidated material is backed up. It is what makes. In this prior art, the space between the hydraulic system and the consolidated material system can be saved by using a single rotary joint specially devised.
However, in this prior art rotary joint, since the hydraulic passage and the solidifying material passage have the same configuration, the cross-sectional diameter of the solidifying material passage is smaller than the required flow rate, and the solidification passage is There is a problem that the flow of the material lacks smoothness. Furthermore, there is a possibility that the caking material remaining in the caking material system may start to be consolidated after the completion of the running construction, and it is necessary to quickly wash the caking material system prior to disassembling the construction apparatus.
Japanese Patent Laid-Open No. 2003-42345 discloses a rotary joint portion obtained by improving the technique of the aforementioned Japanese Patent Laid-Open No. 2003-33969 and penetrating the center of a hydraulic rotary joint portion to dispose a filler rotary joint portion. .

However, in these known techniques, the construction in the large-diameter pipe is in a normal state, and even if the rotary joint used in the above technique is accompanied by the rotational movement of the lining construction device, the operator can perform a braking operation at any time. Is possible.
However, it is difficult for a small diameter pipe to be operated by a regular operator, and this is a bottleneck for application to a small diameter pipe.
In addition, when construction with small diameter pipes is planned, depending on the assemblability of the conventional molding frame, it is impossible or extremely difficult to disassemble the lining construction equipment due to the suspension of pipe making during the construction. It is pointed out as a technical bottleneck that it will lead to

Strip member 200 (see FIG. 23)
FIG. 23 shows an example of a belt-like member used in the lining construction of this embodiment.
The belt-like member 200 has a flat plate shape with a constant thickness, and an appropriate number (seven in the illustrated example) of protrusions 202 are continuously provided vertically in the longitudinal direction of the outer surface. A flange 202 a is formed at the tip of the protrusion 202. A groove 204 or a groove space is formed between the protrusions 202. The inner surface 206 is formed to be substantially smooth.
On both sides of the belt-like member 200, joint portions 200A and 200B are formed that are overlapped and engaged with each other inside and outside. That is, the front edge side joint portion 200A has a base portion of the protrusion 202A at the front end thereof inflated, a concave groove 210 is provided vertically from the inner surface side, and an overhang portion 212 is further provided continuously from the protrusion 202A.

With reference to FIGS. 1-16, the structure of the lining construction apparatus S of this embodiment is demonstrated.
As shown in FIGS. 1 to 4, the lining construction apparatus S includes a pipe making part H and a rotary joint part I connected to the pipe making part H with a link mechanism.
The tube-making part H is arranged on a molding frame 1 having a predetermined width and having a link mechanism composed of a plurality of link frame bodies to form a flexible annular body, and each shaft part of the link mechanism of the molding frame 1. A plurality of guide rollers 2, which are attached via the forming frame 1, include an inner surface roller 3 and an outer surface roller 4 and are driven by a working fluid, and are arranged adjacent to the bonding mechanism portion 5. It consists of the main part of the filler injection | pouring mechanism part 6. FIG.

9 is a link body.

Hereinafter, the detailed structure of each part will be described.
Molding frame 1 (see FIGS. 1, 2, and 5 to 10)
The forming frame 1 is formed into an annular body with a required width, the whole is flexible with a link mechanism in the outer diameter direction, and has lateral rigidity, a part of which is a mounting portion of the joining mechanism portion 5. It becomes. That is, the flexibility of the annular body is obtained from a link chain or a link row in which the link frame 10 having a plurality of rigidity and forming a frame body is slidably connected via the rotating shaft portion 11.

(Link mechanism) (See Figs. 5 and 6)
In this embodiment, as shown in FIGS. 5 and 6, the link frame 10 adopts two types of frame bodies of an outer link frame 10 </ b> A and an inner link frame 10 </ b> B and is arranged alternately.
The outer link frame 10A has an H shape as a whole, and includes side plates 12 that are parallel to each other and a connecting plate 13 that rigidly connects these at the center. Circular shaft holes 14 are formed on both sides of the side plate 12.
The inner link frame 10B is assembled from two identically-shaped divided bodies 10a and 10b having a U-shape, and forms an H shape which is the same shape as the outer link frame 10A as a whole. That is, the divided body 10b has a U-shaped body composed of a short side plate 16 and a back plate 17, and is firmly connected by bolts and nuts (not shown) in contact with the back plates 17 and integrally formed as an H-shaped body. Assembled. A circular shaft hole 18 is formed in the short side plate 16 corresponding to the shaft hole 14 of the side plate 12 of the outer link frame 10A. The divided bodies 10a and 10b have the same shape, and there is no problem even if they are replaced with each other.
Thus, the outer link frame 10A and the inner link frame 10B overlap the short side plate 16 of the inner link frame 10B on the inner side of the side plate 12 of the outer link frame 10A and make the axial centers of the shaft holes 14 and 18 coincide with each other. The shaft portion 11 is inserted through the bearing 20 fixedly held in the shaft holes 14 and 18 to constitute a link mechanism.
In the above configuration, the outer link frame 10A is a single body and the inner link frame 10B is a split body, but these are the reverse modes, that is, the outer link frame 10A is a split body and the inner link frame 10B is a single body. It can be. Alternatively, all of the link frames may be divided bodies.

(Anti-breaking mechanism) (See Figs. 6 and 7)
The link frames 10 can be folded outwards with respect to 180 °, but they are prevented from being folded. However, the mounting portion does not fall under this as will be described later.
For this reason, an anti-breaking mechanism is provided, and an example thereof is shown in FIGS. That is, a stopper recess 22 is provided at the end of the side plate of one link frame 10 (I), and the side plate of the other link frame 10 (II) projects toward the previous link body 10 (I). The stopper 23 to be provided is fixed, and the stopper 23 abuts against one end surface 22a of the stopper recess 22 to prevent the middle break.
Further, the stopper 23 can be folded outward until it comes into contact with the other end surface 22 b of the stopper recess 22. The opening angle (α, for example, 30 °) of the recess 22 is the swinging width. That is, as one aspect, it can be folded outwards up to 150 ° up to 180 °.

Is used for attachment to the joining mechanism section 5. The link frame 10b ′ in the rotational direction of the attachment portion is retracted backward from the front side plate to form a narrow width. The receding width is set to a width sufficient to receive the belt-like member 100.

Thus, the attachment portion is provided with a middle folding mechanism that is opposite to the middle folding prevention mechanism and prevents outside folding and allows middle folding at a certain angle.
That is, as shown in FIG. 9, a concave portion 27 is formed around the rotation axis at the end portion of the side plate of the divided body 26, and a stopper 28 fitted into the concave portion 27 is fixed to the side plate of the divided body 25. The stopper 28 abuts against the end surfaces 27a and 27b of the recess 27 and allows the bend to bend over the range of the spread angle β (for example, 60 °) of the recess 27. In the illustrated example, the stopper 28 abuts against the end surface 27a of the concave portion 27 and maintains 180 °, so that it can be folded inward up to 240 °. Of course, this angle of folding is appropriately determined according to the circumference of the molding frame 1. The middle bending angle is an angle of a circular arc that is symmetric with the circular arc shape of the inner wall surface of the pipe rod P with the 180 ° linear state as the axis of symmetry (y) (see FIG. 22).
In the molding frame 1 of the present embodiment, it is composed of 17 link frames, but this can be freely reduced or increased. In short, it is increased or decreased according to the diameter of the pipe to be constructed.

Lining apparatus S on the lining method ordination is applied to lining in Kanmizo as follows is operated.
20-22 shows the outline | summary of the lining construction of the one aspect | mode. In this construction work, an example of application to a sewer pipe P having a small circular cross section as an underground pipe will be shown. In the figure, Q1 is an upstream human hole and Q2 is a downstream human hole.
As shown in FIG. 20, in the ground portion, an unwinding device T with a turntable around which a belt-like member 200 is wound is disposed on the upstream side human hole Q1 side, and a hydraulic drive source G and a filling are provided on the downstream side human hole Q2 side. A material supply device K is arranged.
That is, the hydraulic drive source G is connected to the hydraulic rotary joint portion 7A of the rotary joint portion I of the construction apparatus S via the hydraulic pipe 300 (feed 300a, return 300b). Further, the filler supply device K is connected to the filler rotary joint portion 7B of the rotary joint portion I of the construction apparatus S through the filler supply pipe 310.
The construction will be done from the upstream side to the downstream side.

Carrying the lining construction apparatus S into the pipe rod P The main lining construction apparatus S is carried into the pipe rod P to be rehabilitated through the human hole Q1. For this reason, the pipe making part H, the rotary joint part I, and the link part 9 are carried into the human hole Q in a disassembled state. The rotary joint portion I is separated from the rotary joint device 7 and the accompanying rotation prevention mechanism 8.
When the tube-making part H is carried into the human hole Q1, the opening of the human hole Q is small, but the fixing pin 36 at one location of the molding frame 1 is not attached, and the molding frame 1 is in series. It is carried into the human hole Q. After carrying in, the pin 36 which has not been mounted is mounted in the human hole Q, and the molding frame 1 is formed into an annular shape. Next, the joining mechanism portion 5 is attached to the molding frame 1, and the filler injection mechanism portion 6 is attached along the joining mechanism portion 5.
The rotary joint portion I is fitted with the anti-rotation mechanism 8 on the rotary joint device 7 and fixed with the mounting bolt 96. The link portion 9 is attached to the rotary joint device 7.

Lining construction Lining construction is performed based on the following procedure.
(1) Connect the hydraulic pipe 300 and the filler pipe 310 to the rotary joint I and push them into the pipe rod P.
In other words, the feed port 300a and the return port 300b of the hydraulic pipe 300 are connected to the connection ports c and d of the hydraulic joint part 7A of the rotary joint part I, and the injection joint pipe 84 of the filler joint part 7B of the rotary joint part I is connected. The filling pipe 310 is connected to the pipe via a joint (not shown).

(2) Pull the belt-shaped member 200 into the human hole Q1, drive the pipe making part H of the construction apparatus S assembled in advance in the human hole Q1, and drive the belt-shaped member 200 together with the driving of the joining mechanism part 5 Frame 1
The belt-shaped member 200 is wound several times (about three times) to produce a lining pipe (this is called a starting lining pipe) Ro. The circumferential length of the inner surface of the starting lining pipe Ro is equal to the circumferential length of the molding frame 1. In addition, the starting lining pipe Ro holds a circular shape in a natural state where no restraining force is applied due to the elasticity of the belt-like member 200.

(3) Inside the human hole Q, the attachment portion of the molding frame 1 attached with the joining mechanism portion 5 is attached to the pipe making portion H in which the starting lining pipe Ro in the above state is assembled. 5 is pulled in the radial direction together with the starting lining tube Ro.
In this way, a lining pipe Ri (which is referred to as an initial lining pipe) Ri is formed as a stage before being inserted into the pipe rod P.
It is convenient to use an appropriate jig such as a shape-retaining tool in the pull-in operation of the mounting portion.

(4) The pipe-making part H in this state is connected via the rotary joint part I and the link part 9, the lining construction apparatus S is assembled, and the working fluid system and the filler system pipe line are connected. Thereafter, the entire construction apparatus S is drawn into the pipe rod P, and the initial lining pipe Ri is temporarily fixed at an appropriate position of the pipe rod P (usually at the inlet end of the pipe rod).
At the time of this pull-in, all of the construction apparatus S including the initial lining pipe Ri is in a state of being accommodated within the inner diameter of the pipe rod P.

(5) The construction device S is driven to produce the lining pipe R.
That is, the feed roller 73 of the feed mechanism 52 abuts against the tube wall of the pipe rod P, and receives the reaction from the tube wall to rotate the construction apparatus S. Further, the inner and outer surface rollers 3 and 4 of the joining mechanism portion 5 are rotationally driven, and with the clamping force between the inner surface roller 4 and the outer surface roller 5, the joint structure at the closing portion Z of the belt-like member 200 is connected to the initial lining pipe Ri. The newly supplied belt-like member 200 is joined. The molding frame 1 moves along the inner surface of the molded lining pipe R with the rotation of the guide roller 2. As a result, the belt-like member 200 is spirally wound, and the lining pipe R is manufactured.
And the formed lining pipe | tube R is left, the whole this construction apparatus S revolves in a pipe circumferential direction, and it advances to a pipe-axis direction, adding the new strip | belt-shaped member 200. FIG.

(5A) In this process, in the joining mechanism portion 5 of the construction apparatus S, the lining pipe R is bent inward to form a concave curved surface, and returns to a circular shape, that is, a convex curved surface as the joining mechanism portion 5 passes. The running tube R remaining in the shape returns to a circular shape due to its elasticity.
That is, as shown in FIG. 21 and FIG. 22, the portion of the lining pipe R gripped by the joining mechanism portion 5 receives a pressing force in the center direction via the feed roller 73 and the joining mechanism portion 5, and is depressed. Although it is a curved surface (A), it gradually becomes a convex curved surface (B) due to the elasticity of the lining pipe R as it moves away from the joining mechanism portion 5 in the circumferential direction and in the depth (axis) direction.

(5B) At the same time, in this step, the filler supply device K is driven to send cement paste (or mortar) through the supply pipe 310, and through the filler rotary joint portion 7B, A predetermined amount of cement paste is injected from the injection port 40 a of the injection tube 40.
The fluid filler is discharged into the space of the concave curved surface (A) of the lining pipe R at the back of the outer surface roller 4 of the joining mechanism portion 5, and the concave curved surface (A) is gradually convex as the joining mechanism portion 5 advances. It changes into a curved surface (B) and is in close contact with the wall surface, whereby the filler spreads wide and enters the groove portion 204 of the belt-like member 200.

(5C) In this step, the belt-like member 200 is sequentially supplied from the unwinding device T arranged on the ground portion. As shown in FIG. 20, an example of the configuration of the unwinding device T is such that a turntable 324 can be freely rotated via a trochanter 322 on a circular rail 320 arranged around the opening of the human hole Q1. Then, a winding drum 326 around which the belt-like member 200 is wound so as to be able to be fed is rotatably supported on the turntable 324. As a result, the rotation of the turntable 324 along the circular rail 320 on the horizontal plane and the rotation of the winding drum 326 on the vertical plane are combined.
The band-shaped member 200 is twisted and rotated in accordance with the pipe making operation. In the unwinding device T, the turntable 324 follows this in synchronization with this rotation.

(6) The injected filler (cement paste / cement mortar) is filled between the pipe culvert P and the piped lining pipe R and develops the required strength by solidification. Thus, the lining pipe R and the pipe rod P are integrated.

(7) The lining pipe R is constructed over a predetermined length of the pipe rod P (usually the full length section from the human hole Q1 to Q2). When the lining pipe R is applied to the entire span, the rotary joint portion I comes out into the human hole Q2.

(8) Disassemble the construction device S and carry it out of the manhole Q.
(8a) First, the rotary joint portion 7B for filler is removed. That is, the injection pipes 40 and 42 are separated from the filler rotary joint portion 7B, and the injection joint pipe 84 is pulled out of the rotary joint device 7 at the filler rotary joint portion 7B. The filler system is cleaned as soon as possible.
Further, the pipe 300 is removed from the hydraulic joint 7 </ b> A of the rotary joint I even when attached to the working pressure fluid system (hydraulic system).
The accompanying prevention mechanism 8 is removed in accordance with the reverse procedure of the assembly.

(8b) Next, the pipe making part H is disassembled.
That is, the link part 9 is removed, the joining mechanism part 7 is removed from the pipe making part H, the retaining pin 36 of the detachable joint 30 is pulled out, and the molded frame 1 is disassembled.
These are carried outside through the human hole Q.
With the above, the construction work of this embodiment is completed.

  In the middle of this lining construction, when it is necessary to stop the pipe making action of the lining pipe R and to dismantle the lining construction apparatus S, the rotary joint I and link part 9 are sequentially disassembled by the procedure (8).
