It relates to the repair of the pipeline facility to be constructed.

When pipelines such as sewage pipes buried in the ground become obsolete, a pipe lining method for repairing the pipeline by lining the inner circumferential surface without digging the pipeline out of the ground has been proposed and has already been provided for practical use.

The tube lining method inserts, for example, a tube lining material formed by impregnating an uncured thermosetting resin into a tubular resin absorbent material while inverting the pipe lining material into the pipeline by the fluid pressure, and inserts the tube lining material into the pipeline by the fluid pressure. It is a method of repairing a pipe line by forming a plastic pipe in a pipe line by pressing a circumferential wall and heating a pipe lining material by arbitrary methods, and hardening the thermosetting resin impregnated therein.

In addition, the tubular unit (single tube) is assembled by connecting the inner surface plate constituting the inner circumferential surface and the segment member (block body) integrally formed of plastic with the outer wall plate mounted on the peripheral edge of the inner surface plate in the circumferential direction. Also, a method of repairing a pipe line using a rehabilitation pipe formed by connecting the pipe unit in the pipe length direction is also known (Patent Document 1), and this method is used for a large diameter pipe.

(Example)

The rehabilitation pipe of the present invention is placed in an existing pipe by assembling the block-shaped segment member in the circumferential direction and the pipe length direction. As shown in Figs. 1 and 2, the segment member 1 serving as the unit assembly member of the rehabilitation pipe has an inner plate 101, and the inner plate 101 has a predetermined angle for dividing a plurality of circumferences, for example. For example, it is formed as a plate having a predetermined width curved in an arc shape of 72 degrees, and the lower surface (upper surface in Fig. 2) becomes the inner circumferential surface of the reinforcement tube, and the circumferential direction of the arc is the circumferential direction and width of the reinforcement tube. The direction becomes the pipe length direction of a rehabilitation pipe. A plurality of rectangular openings 101a are formed at each of both ends in the circumferential direction of the inner surface plate 101 to perform the work for connecting the segment members 1 in the circumferential direction from the inside.

At the circumferential edge of the inner surface plate 101, an outer wall plate surrounding the inner surface plate is provided so that the inner surface plate 101 is erected. The outer wall plates are provided at the same height as the two side plates (lateral plates) 102 and 103 of the same height, which are respectively installed in an edge portion along the longitudinal direction (circumferential direction) of the inner surface plate 101 and the side plates 102 and 103. It consists of two end plates 104 and 105 which are installed upright in the edge portion along the short side direction (pipe length direction) of the inner surface plate 101, and each side plate 102 and 103 is a pipe length direction for the connecting member mentioned later. A plurality of through holes 102a and 103a are formed in the circumferential direction at predetermined intervals (14 here) in the circumferential direction, and the segment members 1 are connected to the end plates 104 and 105 in the circumferential direction. The through holes 104a and 105a for inserting the bolts through are formed in a plurality of places. (See also FIG. 4).

In addition, a reinforcing plate 106 for reinforcing the mechanical strength of the entire segment member 1 at the same height as the side plates 102 and 103 is formed on the upper surface of the inner plate 101 inside the side plates 102 and 103. The lower reinforcement plate 107 is provided upright, and each of the reinforcement plates 106 and 107 has a plurality of through holes 106a and notches 107a for inserting and connecting the connecting member in the pipe length direction. It is formed at a position corresponding to each of the through holes 102a and 103a of the side plates 102 and 103. Further, on both inner surfaces of the side plates 102 and 103 and both side surfaces of the reinforcing plates 106 and 107, small right triangle convex plates 103b, 106b and 107b (side portions of the convex plates) which are laterally attached to prevent respective deformations. 1, which cannot be seen since it is impossible to show in FIG. 1, are formed in a plurality of places, and have a rib structure, thereby increasing the strength of the segment member 1.

The inner plate 101, the side plates 102 and 103, the end plates 104 and 105, the two reinforcement plates 106, the two reinforcement plates 107, and each convex plate are transparent and translucent Or integrally molded from opaque plastic, an integral segment member 1 made of plastic with circular arcs is formed. As the transparent plastic, vinyl chloride, ABS, Durastar polymer (trade name) and the like are used. As the translucent plastic, PVC, polyethylene and the like are used. As the opaque plastic, PVC, polyester, ABS, polyethylene, polypropylene and the like are used.

Since the segment member functions as an arbitrary rehabilitation member or a repairing member, the segment member is not limited to an arc shape or a fan shape as shown in FIG. 1, and may be rectangular or right angle depending on the cross-sectional shape of the existing pipe, its size, or the repair point of the existing pipe. It can also be rounded, and bent shape.

As shown in FIG. 3, the segment member 1 having such a configuration sequentially rotates the segment members in the circumferential direction such that the outer surfaces of the end plates 104 and 105 are brought into close contact with each other so that the inner surface of each inner plate becomes a uniform surface. By assembling and assembling, the ring-shaped closed short pipe 10 (hereinafter referred to as a pipe unit) as shown in Fig. 5 can be obtained.

3, 5, and the corresponding drawings, the segment members are shown with inner plates 101, side plates 102, 103, and end plates 104, 105 which are the main structural members. 106 and 107, reinforcing structures such as convex plates, connecting through holes, and the like are omitted in order to avoid the complexity.

As shown in FIG. 12, the reinforcement pipe is laid in the existing pipe 21 through the manhole 20, and the segment member 1 is circumferentially shown in FIGS. 3 and 4. This is done by connecting in sequence. As shown in detail in FIG. 4, the circumferential connection of the segment members is such that each segment member 1 has the same inner surface of each inner surface plate 101, and the outer surface of each side plate 102 has the same surface. Positioning so that the outer surface of each side plate 103 becomes the same surface, the outer surface of the end plates 104 and 105 of each segment member 1 are brought into close contact, and the bolt from the opening 101a of the inner surface plate 101 is fixed. (6) is inserted into the through holes 104a and 105a, and the nut 7 is screwed to fasten both end plates 104 and 105. In addition, the cross section of the segment member on the left side in FIG. 4 shows a vertical cross section along the BB line of FIG. 1, and the cross section of the segment member on the right shows a vertical cross section along the corresponding line in the end plate 104 of FIG. 1. have.

Here, since the concave portions 104b and 104c are formed in the end plate 104 and the convex portions 105b and 105c fitted to the concave portion are formed in the end plate 105 over the entire length in the tube length direction. The positioning of both segment members at the time of connection can be facilitated, and the watertightness of the connecting portion can be improved by applying a sealing material (not shown) to the fitting portion. In addition, when the connection is completed, each opening 101a is sealed by a cover (not shown) or the like. At this time, the inner surface of the cover is connected to the inner surface of each inner plate 101 so that a uniform inner surface is formed.

In this way, as shown in FIG. 5, the ring-shaped pipe unit 10 which has a shape when a round pipe is cut round by predetermined width D perpendicularly to the pipe length direction X can be assembled. The segment member 1 corresponds to a block-shaped member obtained when the pipe unit 10 is cut along the radial direction R and divided (preferably equally divided) into a plurality of pieces in the circumferential direction. ) Is smaller than the inner diameter of the existing pipeline whose outer diameter is to be repaired.

As shown in Figs. 6 and 7, the pipe unit 10 assembled in this way is laid in the pipe length direction by sequentially connecting the respective segment members in the pipe length direction. As shown in Fig. 7, the connection in the tube length direction has one end having a threaded portion 11a, and a nut portion 11c having a threaded hole 11d for screwing the threaded portion 11a at the other end. It is performed using the connecting member 11 which consists of metal which integrated the both ends by the rod 11b.

In Fig. 7, the segment members 1 and 1 'of each of the two pipe units are shown, and the cross section of the segment members 1 and 1' corresponds to the vertical cross section along the line A-A in Fig. 1. In Fig. 7, it is assumed that the connecting member 11 on the right side is already connected to the nut part 11c of the other connecting member indicated by a dashed line and is fixed to the segment member 1 by being caught by the segment member 1. . In this state, in order to connect the other segment member 1 'with the segment member 1, first, both the segment members 1 and 1' are formed so that the inner surface of each inner plate 101 is continuously uniform. The nut member 11c protruding from the side plate 102 of the segment member 1 is aligned, and the outer surfaces of the side plates 102 and 103 of both segment members 1 and 1 'are brought into close contact with each other. It fits into the through-hole 103a of the side plate 103 of 1 '. Subsequently, the connecting member 11 'is inserted through the through-hole 102a of the side plate 102 of the segment member 1', and the threaded portion 11a 'is passed through the nut portion 11c of the connecting member 11. Threaded into the screw hole 11d. When the nut part 11c 'of the connecting member 11' is screwed into the reinforcing plate 106 of the segment member 1 ', the connecting member 11' is connected to the segment member 1 '. And takes At this time, since the nut portion 11c 'tightly tightens the reinforcing plate 106 of the segment member 1', the engagement of the segment member 1 'and the connecting member 11' is surely performed, and the connecting member ( 11 'is fixed to the segment member 1', and both segment members 1 and 1 'are connected. Since the connection of each segment member is performed using four connection members, for example, per segment, both segment members 1 and 1 'are firmly connected in the pipe length direction.

Further, since the convex tub 102c is formed in the side plate 102 of the segment member, and the concave tub 103c fitted to it is formed in the side plate 103 over the entire circumference in the circumferential direction of each side plate, the circumferential direction Similarly to the connection in the pipe length direction, the operation of aligning and bringing both segment members into close contact with each other in the pipe length direction becomes easy, and by applying a sealing material not shown in the fitting portion, the watertightness of the connecting portion can be improved.

In addition, in Fig. 7, when the segment member 1 is the first segment member in the tube length direction, the connecting member as shown in Fig. 7 cannot be used, so that the nut part which can be fixed to the segment member 1 by any means ( A fixing member having the same structure as 11c) is used as a connecting member.

As described above, as shown in FIG. 12, the rehabilitation pipe 40 can be placed in the existing pipe 21 by sequentially connecting the pipe units 10 in the pipe length direction in the existing pipe 21.

Here, the existing pipe 21 is not necessarily limited to extending in a straight line, and may be bent as shown in FIG. 8. It is necessary to bend the rehabilitation pipe in accordance with the degree of bending in the curved portion of the existing pipe. Thus, as shown in Figs. 9 and 10, the pipe unit 10 is coupled through the coupling member consisting of the bolt 30 and the nut 32 as follows.

In FIG. 8, the existing pipe 21 is shown as a horizontal sectional view, and the rehabilitation pipe is seen from the top downward. The existing pipe 21 is bent from the straight portion 21a at the bent portion 21b, and subsequently becomes the straight portion 21c. The pipe units are assembled in order from the left to the right direction. The pipe units 10 are sequentially connected in the right direction so as to extend in a straight line by the connecting member 11 along the straight portion 21a, and the pipe center axis X1 of each pipe unit is a straight portion ( Assembled to coincide (or offset by a predetermined amount) the tube central axis of the existing tube in 21a). Here, since the existing pipe 21 is bent at the bent portion 21b and continues to be a straight portion 21c, the next pipe unit 10 'is the pipe center whose tube center axis X2 is the conventional pipe center. It is arrange | positioned so that it may incline by the angle (alpha) according to the degree of curvature of an existing pipe | tube from the axis X1. At this time, the angle which the surface of the side plates 102 and 103 of the segment member which comprises a pipe unit makes also becomes an angle (alpha) as shown in FIG.

Subsequently, as shown in detail in FIG. 10, the bolt 30 is connected to the hole 31a of the spacer 31 and the segment member on the left side through the spacer (washer) 31 shown in FIG. 11A. The through-hole 103a formed in the side plate 103 of 1) and the through-hole 102a of the side plate 102 of the segment member 1 of the right side are inserted through, and the screw part 30b of the bolt 30 is nut-connected. Screw in (32) to connect both pipe units. At this time, as shown in Fig. 11A, the thickness of the spacer 31 is inclined at the same value as the inclination α of the tube central axis, so that the surface 31c of the spacer having the inclination is inclined. The stopper 30c fixed to the surface of the side plate 103 of the segment member, the flat surface 31b of the spacer to the surface of the head 30a of the bolt 30, and the side plate 102 fixed to the bolt. By abutting with each other, the angle formed by each side of the side plate 103 on the left side and the side plate 102 on the right side can be adjusted to α, so that both pipe units can be joined at a predetermined distance.

Here, as shown in FIG. 11 (B), the spacer 31 is cut at a predetermined angle by cutting the corner member 34 on which the U-shaped hole 34a is formed by a dashed-dotted line. Since it can be set as the spacer which has inclination, the spacer which has the angle inclination according to the curvature of an existing pipe | tube can be prepared, and the inclination angle (alpha) of a pipe unit can be matched with the curvature of an existing pipe | tube.

As shown in Fig. 9, the coupling between the bolt and the nut is performed at three locations per segment, but if necessary, the coupling may be performed at more locations, or at fewer locations. . In addition, since the through holes 102a and 103a of the side plate through which the bolt is inserted may not be able to use the hole (FIG. 1) formed from the beginning, in that case, the through holes 102a and 103a are newly formed according to the joining position. In addition, as shown in FIG. 9, the space | interval of both pipe | tube units joined by a bending part may be made to approach until it contacts substantially, since the lower part is not separated.

In this way, after joining both pipe units in the curved part of an existing pipe | tube, the pipe units are sequentially connected to the right direction so that it may extend linearly again in the linear part 21c. Then, the gap between the two tube units formed in the bent portion is covered with a coating material 50 made of a curable resin sheet. This state is shown in FIG. 13, and the coating material 50 is only partially shown in FIG. 13, but is provided over the entire circumference of the pipe unit so as to cover all the gaps between both pipe units 10, 10 '.

The resin sheet of the coating material is composed of a thermosetting reinforcement plastic made of a reinforcing fiber impregnated with a thermosetting resin and a curing agent. As the reinforcing fibers, glass fibers, carbon fibers, metal fibers or organic fibers, and natural fibers are used. It has the effect | action which makes a thermosetting resin react with a radical, For example, organic peroxides, such as a benzoyl peroxide and a lauroyl peroxide, are used, An unsaturated polyester resin, an epoxy (meth) acrylate resin, etc. are used as a thermosetting resin. As described above, when the gap between both pipe units is covered with the coating material 50, and then heat treatment, the resin sheet is bonded to the pipe unit by curing the thermosetting resin, so that the gap between both pipe units 10, 10 'is closed. It can be integrated with the tube unit in the form of sealing. Since the resin sheet has very high strength and high corrosion resistance, the strength and corrosion resistance of the rehabilitation pipe in the bent portion can be significantly increased.

In addition, when the existing pipe 21 has a degree of curvature larger than the degree of curvature shown in Fig. 8, the central axis of one pipe unit is not only inclined and coupled, but also the subsequent pipe unit is inclined and joined. There is a need. In this case, the plurality of pipe units are sequentially inclined by a predetermined angle in the same manner as shown in FIG. 10 and the like, so that the existing pipes that are bent at an arbitrary angle are also bent in the existing pipes. Can be laid.

As described above, the coupling member 60 or 70 shown in FIGS. 14A and 14B may be used as the coupling member for the inclined coupling of the pipe unit, rather than the connector such as the bolt and the nut.

In the coupling member shown in Fig. 14A, stoppers 60b and 60d are fixed to both ends of a rod 60c made of a bendable elastic material, and the ends thereof are connected with metal screw parts 60a and 60e. (60), the threaded portions (60a, 60e) are inserted through the through holes (103a) of the side plate (103) of the segment member and the through holes (102a) of the side plate (102), respectively. By screwing and fastening, both pipe units can be combined. At this time, since the rod 60c of the connector can be bent arbitrarily according to the degree of curvature of the existing pipe, it is possible to connect the pipe unit at a predetermined inclination angle according to the degree of curvature, and the stopper 60b, 60d to the connector 60. ) Is installed, it is possible to combine both pipe units at a predetermined distance.

On the other hand, the coupling member shown in Fig. 14B has an elastic spring 70c, a stopper 70b and a threaded portion 70a at one end thereof, and a stopper 70d and a threaded portion 70e at the other end thereof. And a threaded portion (70a, 70e) through the through hole (103a) of the side plate 103 of the segment member and the through hole (102a) of the side plate (102), respectively, and the nut (71). 72), by screwing together tightly, it is possible to join both pipe units. At this time, the spring 70c of the connector can be bent at any angle according to the degree of curvature of the existing pipe, and can also be stretched so that the pipe unit can be connected at a predetermined inclination angle according to the degree of bend. In addition, by interposing the space holding member (spacer) 73 between both side plates (102, 103), it is possible to combine both pipe units at a predetermined distance.

In addition, although about 3 coupling | bondings are used per segment member using these connectors 60 and 70, these can be mixed instead of the same connector. For example, if it joins at three places per segment, one place uses the connector shown in FIG. 14 (A), the other two places are used for connection using the connector shown in FIG.
