Abstract

PURPOSE:To stably set a repairing pipe at a predetermined position skillfully by forming a holding member fit for a space between the repairing pipe and a pipe at the outer circumference of the repairing pipe and inserting and holding the member in the pipe. CONSTITUTION:A holding member 12 having a fitting portion 10 and or leg portion 11 is fixed to the outer circumference of a repairing pipe by adhesion or a bolt etc. It makes the holding member to be fitted readily that a flat face 16 is formed at the outer circumference of the repairing pipe. At this time, a seat portion may be provided at the fitting portion of the holding member of the repairing pipe. The length of a holding member is determined according to the width in a radial direction between the repairing pipe and the pipe. The repairing pipes are inserted into the pipes in turn and the repairing pipes are held in the pipes by the holding members. After holding, according to its necessity, concrete, forming materials or other fluid solidification materials 16 are filled in the space between the repairing pipe and the pipe to unite them.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a repair pipe facility method for repairing a pipe by inserting a new repair pipe into the pipe, the structure of the facility, and the repair pipe.

[Conventional technology]

As a method of repairing piping, there are two known methods: placing a tube on the inner surface of the pipe and filling the gap between the tube and the pipe, and creating a framework on the inner surface of the pipe and inserting a new thin tube into it. There is.

[Problem to be solved by the invention]

The method of stretching a tube over the inner surface of the pipe required a large-scale device, and the inner surface of the tube did not match the reference position of the pipe. Also, the method of creating a framework on the inner surface of the pipe can be used if the diameter of the pipe is large, but it cannot be used if the diameter is so small that a person cannot enter, and the framework requires considerable effort.

The present invention improves these points and makes it even better, and provides a method that can be easily implemented, is stable, durable, and economical in accordance with the reference position of the piping.

[Means to solve the problem]

The present invention includes a repair pipe that can be inserted into piping, and a support member is provided around the outer periphery of the repair pipe. The repair pipe is inserted into the pipe and supported within the pipe by its support member. The repair tube and support member can be made of synthetic resin.

[Function and Examples]

When the pipe (1) is used for a certain period of time, it may bend due to subsidence or uplift of the ground, and may shift from its reference position (2). If the pipe is thick (large enough for a person to enter), the amount of deviation (h) can be measured by entering the pipe with a level and a staff, or if it is thin, installing an inclinometer (sensor) inside the pipe.
A television camera (4) equipped with figure). The positional relationship of the pipes is investigated based on the data, and when the repair pipe (8) is inserted into the pipe, the radial width ( Know (b) (Figure 1).

The repair pipe shown above is made of durable hard synthetic resin such as FRP, PVC, polyethylene, etc., but it is also made of synthetic resin with metal embedded, concrete, ceramics, hard rubber, and other durable materials. It is formed. A support member a3 having a mounting portion αO and a leg portion aυ is fixed to the outer periphery of the repair pipe (8) by adhesive Q3, bolt α4, or other fixing means C2. Note that if a flat surface α0 is formed on the outer periphery of the repair pipe, the support member can be easily attached. In this case, a seat may be provided at the support member mounting portion of the repair pipe. The length of the support member is determined based on the radial width between the repair pipe and the piping. That is, in the support member shown in FIG. 3, the width (t) of the space (in the height of the support member as shown in FIG. 7) is
so that it becomes In this case, as shown in Fig. 3, a longer support member may be made from the synthetic resin described above and then cut into pieces corresponding to the width described above to serve as support members at various locations, but support members of each length may be prepared in advance. You can leave it there.

The repair pipes are sequentially inserted into the pipe C, and the repair pipes are supported within the pipe by the supporting members.

After supporting, if necessary, the space between the repaired pipes can be filled with concrete, foam material, or other fluid solidified material Qe to integrate them.

In FIGS. 5 and 3, the mounting surface of the support member is formed into a curved surface θ corresponding to the outer peripheral surface of the repair pipe.

Note that when the support member of the repair pipe is made of synthetic resin, it has appropriate elasticity and can be easily inserted into the pipe.

FIG. 2 shows a support member provided with a spring αe.

Figures ♂ and 9 show that the length of the support member can be freely adjusted. In Figure ♂, the mounting plate a9 and the leg plate are provided with long grooves in the leg plate. form a bolt,
In Fig. 9, a pole-shaped leg rod is provided on the fixture 4 and is screwed into it.

Figures 1θ and 11 show a case where a groove (2) is formed on the outer periphery of the repair pipe, and the mounting end (c) of the support member is engaged with the groove (2).

The above-mentioned supporting member can be made in various other structures, and as long as the supporting member can be supported within the above-mentioned piping, a plurality of supporting members may be arranged around the outer periphery of the supporting member in the same row or in a staggered manner in any other suitable manner. It can be attached or integrated.

〔Effect of the invention〕

The present invention is constructed as described above, and can quickly and stably fix the repair pipe into two branches at a predetermined position, as well as smooth the flow of fluid. If filled with material, the repaired pipe will be made even stronger (-
can be supported. Furthermore, the repair pipe can be made of synthetic resin, which is economical in terms of cost, and also allows the repair pipe to be smoothly inserted into the piping due to its light weight and the elastic action of the support member.
