The installation of the inlet sealing member may be divided into a step of manufacturing the inlet sealing member 4 and a step of inserting the prepared inlet sealing member 4 into the end side of the conduit 1 and installing it.

Referring to the manufacturing step of the sealing member 4 as follows. The inlet sealing member 4 has a cylindrical shape and has a configuration consisting of an insertion cylinder portion 5 formed of a resin material and a flange portion 6 extending outward from an end of the insertion cylinder portion 5. The insertion tube portion 5 made of a tubular resin material is bonded to both ends of a nonwoven fabric of plastic fibers or a strip-shaped nonwoven fabric in which glass fibers are combined with plastic fibers by sealing or bonding, and processing into a tubular shape. And it impregnates unsaturated polyester resin, an epoxy resin, etc. which are uncured thermosetting resin here. The insertion cylinder 5 is preferably manufactured in a multilayer structure of two or more layers. That is, as shown in Figs. 1A, 1B, 2A, and 2B, the flange portion 6 'formed at the end of the first tubular resin material 31 is in the form of a petal, as shown in Fig. 1B. The first tubular resin material 31, except for the portion that is cut out and cut out in the form of petals, is removed from the mold 40. And the donut-shaped agent which impregnated the liquid thermosetting resin in the 1st tubular resin material 31 including the cutout part 31a cut in the shape of the leaf, and cut it out according to the size of the flange part 6 'on it. Two resin materials 33 are stacked and combined. In addition, the flange portion 6 "of the superimposed second resin material 33 is also impregnated with a liquid thermosetting resin and combined with the flange portion 6 ', thereby producing a two-layer tube sealing member 4. .

The tube sealing member 4 is hardened so that the flange portion 6 has the same size and the same shape as the flange portion 2 of the conduit 1, and the tubular resin portion other than the flange portion 6 is inserted. The cylinder part 5 is left in an uncured state.

The liquid thermosetting resin used to form the flange portion 6 of the sealing member 4 includes unsaturated polyester, vinyl ester, epoxy resin, and the like, and is preferably the same type of resin used for the lining material 3. And the flange part 6 of the tube sealing member 4 corresponds to the bolt hole 2a (refer FIG. 4) formed in the flange part 2 of the edge part of the pipe line 1, as shown to FIG. 2A and FIG. 2B. Holes 6a are formed at equal intervals.

The tube sealing member (4) produced as described above is installed at the end of the conduit (1) to be repaired. Specifically, the method for installing the inlet sealing member 4 is as follows. As shown in Figs. 3 and 5, the insertion tube portion 5 of the tube sealing member 4 is inserted into the conduit 1, and the flange portion 6 is connected to the flange portion 2 of the conduit 1. It is positioned so as to face the predetermined space 8.

In this state, the spacer 7 is interposed between the space 8, that is, the flanges 2, 6, so that the space 8 can be secured and maintained constantly, and a tube may be used by using a clamp or the like. The sealing member 4 and the spacer 7 are temporarily fixed to the flange portion 2 of the conduit 1. In this case, the means for temporarily fixing may include a bolt hole 2a of the flange portion 2 and a bolt 51 coupled through the hole 6a and a nut 52 coupled to the bolt 51. .

Here, in order to protect the lining material 3 from impact pressure or the like after the lining, a tubular reinforcement cloth 10 and a net 11 as a liner member may be additionally used. The tubular reinforcement cloth 10 is sealed to the outside of the front end of the tube sealing member 4 in the lining material reverse oscillation side, as shown in Figure 5, the lining material (3) reversely inserted into the pipe line 1 is unfolded in the form of a tube Due to this, the outer circumferential front surface of the lining material 3 is covered. In the inversion reaching end (refer FIG. 3) which the inverted lining material 3 reaches, the tubular reinforcement cloth 10 is cut | disconnected in line with the pipe line 1, and the tube inside the pipe end of the tubular reinforcement cloth 10 is carried out. After inserting the insertion cylinder part 5 of the sealing member 4, the lining material 3 is reversely inserted in the insertion cylinder part 5 inside.

Further, a tubular net 11 having a shorter length than the reinforcement cloth 10 is inserted into each of both ends of the tubular reinforcement cloth 10 at the end of the tubular reinforcement cloth 10, and the tubular net ( One end of 11) is joined to the tubular reinforcement cloth 10 by sewing or bonding. The tube sealing member 4 is joined to the other end of the tubular reinforcement cloth 10 to which the tubular net 11 is joined, and to the other end thereof, and the tubular reinforcement cloth 10 over the entire length of the inside of the pipe line 1. Place it. At this time, the end of the tubular reinforcing fabric 10 is joined to the reverse oscillation end of the lining material 3, and the end of the lining material 3 is arranged at the reverse end end of the lining material 3. The end which joined the tubular net 11 is arrange | positioned.

That is, the tubular reinforcement cloth 10 is arrange | positioned on the outer side of the insertion cylinder part 5 of the tube sealing member 4, and the tubular net 11 of a short length is arrange | positioned inside the insertion cylinder part 5. The lining material 3 which reverses the inside of the tubular reinforcement cloth 10 reverses the inside of the tubular net 11 when it reaches the junction with the tubular net 11 inside the tubular reinforcement cloth 10. It progresses and progresses simultaneously spreading the insertion cylinder part 5 of the tube sealing member 4 to cylindrical shape. The tubular net 11 is made of a member woven in a net form of resin fiber, glass fiber roving, or carbon fiber roving, and is processed into a tubular shape by fixing both ends with an adhesive or the like from a strip material. That is, the reinforcement cloth 10 is installed inside the pipe 1 for a long length over the entire length of the pipe 1, and the net 11 is provided with a short length only at each of both ends of the reinforcement cloth 10.

Here, the lining material 3 is manufactured by impregnating a liquid thermosetting resin in tubular resin material. The tubular resin material is usually composed of a nonwoven fabric of polyester fiber, but the tubular resin material composed of a nonwoven fabric of a glass fiber composited with polyester fiber is most preferable for the construction method of the present invention because of its low heat shrinkage. As the thermosetting resin which is impregnated into the tubular resin material, unsaturated polyester, vinyl ester, epoxy or the like is used.

As described above, the flange portion 6 of the tube sealing member 4 is inserted by the spacer 7 between the flange portion 2 of both ends of the pipe line 1 by the bolt 51 and the nut 52. Fix it temporarily. The tubular reinforcement cloth 10 is a member obtained by processing a woven fabric such as polyester, polypropylene, polyethylene, etc. into a tubular shape by sewing, and is used when the internal pressure of the repaired pipe line 1 is high, and is not an essential material. It can be selectively employed.

5 is a view showing the reverse insertion state of the lining material (3) after the installation of the sealing member (4), Figure 6 is a view showing the curing state of the lining material (3), Figure 7 is a curing of the lining material (3) FIG. 8 is a view showing the situation of the previous inversion arrival stage, and FIG. 8 is a diagram showing the situation of the inversion oscillation stage during curing of the lining material 3, respectively.

That is, one end of the conduit 1 is joined with the insertion tube portion 5 of the tube sealing member 4, and the tubular reinforcement cloth 10 in which the tubular net 11 is joined to the other end is disposed in the conduit 1. Then, the lining material 3 is reversely inserted into the tubular reinforcement cloth 10 from one end of the pipe line 1.

When the reverse insertion of the lining material 3 is completed, the inside of the lining material 3 is pressurized to bring the tubular reinforcement cloth 10 and the lining material 3 into close contact with the wall surface of the line 1, and the lining material 3 ) Is pressed with hot water or the like to cure the lining material 3.

When hardening of the lining material 3 is complete | finished, the spacer 7 inserted between the flange part 6 of the tube sealing member 4, and the flange part 2 of the pipe line 1 is isolate | separated.

At this time, even if the curing is finished, the lining material 3, which is in a high temperature state, is thermally contracted together with cooling. The flange 6 of the tube sealing member 4 also contracts, and the deformation of the lining material 3 and the pipe line 1 It is made to be crimped in the space 8 between the flange portion (2). The size of the shrinkage of the lining material 3 increases as the length of the lining material 3 becomes longer. Therefore, the size of the separation space 8 is calculated in consideration of the expansion ratio of the lining material 3 from the length of the pipeline 1 in advance.

When the heat shrinkage of the lining material 3 is finished, the space 8 between the flange portion 6 and the flange portion 2 of the conduit 1 which causes the shrinkage deformation to corrugate is inserted into the bottom of the space 8. The filler 14 including the glass fiber roving 14a and the band-shaped felt 14b impregnated with an epoxy resin on the outer side of the tube portion 5 is wound to fill the entire separation space 8. At this time, in addition to glass fiber roving, the glass fiber composite polyester felt may be processed into a band shape, and may be wound alternately with glass fiber roving. After the wound glass fiber roving is cured, a bolt hole is formed in the flange portion 2. That is, a bolt hole is formed in the part filled by the space 8.

On the other hand, the edge part of the hardened lining material 3 isolate | separates the bulb cover material 12 previously formed in the inner peripheral part of the flange part 6, and, after that, the lining material 3 is a little more than the flange part 6; Cut to protrude outward. Thereafter, the fiber roving in which the epoxy resin as the outer circumferential member 21 is impregnated on the outer circumference of the protruding lining material 3 is wound and cured. The thickness of winding the outer circumferential member 21 does not exceed the thickness of the insertion cylinder portion 5 of the tube sealing member (4).

FIG. 9 is a view showing a situation in which the roving 14a and the band mat 14b as the filler 14 are wound in the space 8, and FIG. 10 is the completion of the roving and the band mat winding in the space 8; It is a figure which shows one situation. In the pipe lining construction method and lining pipe of the present invention, by providing a space 8 in the flange portion 6 of the tube sealing member 4 during the construction process, even if the lining material (3) heat shrinkage, the flange portion (6) Since there is no restraint because it moves and shrinks between the spaces 8, deformation and cracks do not occur, thereby ensuring watertightness and solving the problems of the conventional construction method.

In addition, in the present embodiment, the thermosetting resin is cured by attaching the spacer 7, but it is not necessary to use the spacer 7, and any method may be used as long as an appropriate separation space can be secured.

Since the heat shrinkage occurs due to cooling after thermosetting, the lining material 3 is provided with a detachable spacer 7 between the lining member 3 and the flange portion 6 of the affected sealing member 4 so as to provide a space therebetween. 8) The spacer 7 is fixed with bolts so that elongation or deformation does not occur until curing is completed. By making the spacer 7 detachable, the spacer 7 can be separated at the time when the lining material 3 is cured and heat shrinkage starts. That is, during curing of the lining material 3, the flange portion 6 is fixed at an arbitrary position, and the lining material 3 is cured and thermally contracted at the point at which the shape is determined. The effect is that it can absorb deformation.

The separation space 8 provided between the flange portion 2 of the conduit 1 and the flange portion 6 of the tube sealing member 4 is set to a safe size in anticipation of heat shrinkage of the lining material 3. For this reason, when the thermal contraction of the lining material 3 is completed, shrinkage residual amount generate | occur | produces and a space | interval space does not disappear completely. In addition, the degree of remaining amount of the space 8 varies in accordance with the shrinkage level of the lining material 3. If the space 8 generated here is not completely filled in any way, the flange 6 may break when the flanges 2 and 6 are tightened with bolts and nuts. Therefore, a glass-fiber roving or a band-like felt is impregnated with a liquid epoxy resin, and wound around the outer surface of the cured insertion cylinder portion 5, which is the bottom of the separation space 8, thereby restoring the remaining amount of the separation space 8 irregularly generated. It is very important to fill completely.

The post-curing properties of the filler 14 impregnated with the liquid epoxy resin in the glass fiber roving or the band-like felt are the same as those of the flange portion 6, and the fastening strength transferability by bolts and nuts is also good. Cracks do not occur in the flange portion 6.

Since the glass fiber roving or the band-shaped felt has a flexible characteristic, it is also easy to change the shape freely, and is most preferable as a filler of the space separated from an irregular size.

11 is a view showing the connection between the pipeline after the lining is completed and the new joint pipe. Since the plate | board thickness after hardening becomes thick at the edge part of the lining material 3 which the insertion cylinder part 5 and the lining material 3 overlap and harden | cure, the inner diameter difference arises with the new joint pipe 13. In addition, when the lining material 3 is cut in line with the tip of the portion protruding from the flange portion 6 and then connected to the new joint pipe 13, a step due to the inner diameter difference occurs at the connection portion, and the fluid flow after construction. It is a cause of inhibition. On the other hand, in the present embodiment, the lining material 3 is cut out by slightly protruding from the flange part 6, and the inner surface of the protruding part 3a is cut at an angle to remove the step to form an inclined surface so as not to disturb the flow of the fluid. It is desirable to. The inner diameter difference of the lining material 3 and the new joint pipe 13 becomes a thick part of the insertion part 5, and a clearance arises. In this embodiment, it is preferable to wrap the outer diameter member 21 made of roving of glass fiber or carbon fiber impregnated with an epoxy resin around the periphery of the protrusion part 3a to fill the inner diameter difference.

By performing the end treatment in consideration of the heat shrinkage of the lining material 3 as described above, it is possible to ensure the watertightness between the pipe line 1 and the new joint pipe 13 and to provide a lining construction that can smoothly flow in the bonding portion. It can be done.

In addition, this invention is not limited to the above embodiment, A various deformation | transformation is possible. For example, it can also be constructed without providing the tubular reinforcement cloth (liner member) 10 in the insertion cylinder part 5 of the tube sealing member 4.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and the present invention is not limited to the specific embodiments of the present invention without departing from the spirit of the present invention as claimed in the claims. Anyone skilled in the art can make various modifications, as well as such modifications are within the scope of the claims.
