Abstract

The utility model relates to a water pipe lining pipe and is a soft water pipe which is designed for the existing water pipe and can be lined in the existing water pipe by using an auxiliary tool. Therefore, the paved water pipe is double-pipe structure. An outer pipe (1) is the existing hard material water pipe, and a lining pipe (2) is a soft material inner pipe. A small hole (3) for checking the water leakage is arranged on the wall of an end port of the outer pipe (1). When the inner pipe lining pipe leaks water, the water can flow from the small hole to be discovered. Therefore, the lining pipe which leaks the water can be evacuated and replaced. The proposal of double pipes paving the water pipe not only can contribute to discover the position of the water leakage but also can carry out the rehabilitation work under the condition of not tearing up a damaged building on the ground. The water pipe lining pipe saves labor, time and material and can use an old water pipe as the outer pipe. An auxiliary tool steel wire soft rope (4) is inserted in the water leakage segment old water pipe. The lining pipe is sheathed by a pipe connecting sheath (6) from the position of the pipe connecting head of the other end of the water pipe, and the lining pipe is towed and penetrated to the position of the connecting head of the end of the water pipe in the pipe.

Description

The water pipe internal lining pipe

1) technical field under

The utility model relates to the water pipe series products, is a kind of convenient pipe that water pipe leaks of repairing specifically, especially can implement a kind of water pipe internal lining pipe of repairing under the state that does not excavate ground or building.

2) background technique

Now, known supply channel installation method underground or that building is interior all is to adopt the method for burying underground, and water pipe is the metal matter pipe or the plastic tube of single wall or applies and mould metal tube.List is layed in underground shortcoming with these water pipes and is, is not easy in time to find leakage point when burying when leaking appears in water pipe line, and will repairs, and must excavate ground or tear the damage building open, and considerably time-consuming effort is taken thing.If new and old water supply network road is wanted in a city, the height of the big expense of its difficulty, it is newly-built really to would be better.

3) summary of the invention

Lay the defective that single water pipe exists in order to overcome in the maintenance of leaking, the utility model provides a kind of water pipe internal lining pipe, and it not only helps in time to find to leak the place, and can implement repair not excavate ground or to tear the mode of decreasing building open.

The technological scheme that its technical problem that solves the utility model adopts is: just can serve as a contrast soft water pipe---internal lining pipe (2) in it for existing water pipe design is a kind of by assistant tool, the water pipe that this bar shop is built is a double pipe structure, its middle external tube (1) is existing hard material water pipe, and internal lining pipe (2) is managed in the softwood matter.For ease of checking the water pipe situation of whether leaking, on outer tube (1) port wall, be provided with aperture (3).In case in the pipe internal lining pipe leak, can flow out and in sight from aperture, can judge in view of the above the internal lining pipe that leaks is withdrawn from replacing.If old water lines is leaked, can utilize old water pipe to make outer tube (1), assistant tool steel wire tightrope (4) is inserted in the old water pipe of the section of leaking, after wearing out from the other end pipe fitting joint, internal lining pipe (2) is overlapped to bind to draw penetrate Guan Zhongzhi local terminal joint and get final product with taking over cover (6).

The beneficial effects of the utility model are, have changed to upgrade the original practice that water pipe need excavate ground or building, and making the work of repairing the pipeline that leaks no longer is the thing of time-consuming effort expense thing.

4) description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is this embodiment's a generalized section.

Fig. 2 is the side view of Fig. 1.

Fig. 3 is the schematic representation of its assistant tool.

In the drawings, 1. outer tube 2. internal lining pipes 3. apertures 4. steel wire tightropes 5. flake down winches 6. are taken over cover.

5) embodiment

In the embodiment shown in fig. 1, internal lining pipe (2) is through in the outer tube (1), is provided with aperture (3) at the port of outer tube, the assistant tool that steel wire tightrope (4) uses when replacing internal lining pipe (2), and its is received and is entangled on the flake down winch (5), establishes at the fag end end and takes over cover (6).

Claims

1, a kind of water pipe internal lining pipe, it is characterized in that: be a kind of soft water pipe---internal lining pipe (2) that has in the water pipe that serves as a contrast by assistant tool, spreading the water pipe of building like this is double pipe structure, outer tube (1) is existing hard material water pipe, internal lining pipe (2) is managed in the softwood matter, is provided with the aperture (3) of checking the usefulness of leaking on outer tube (1) port wall.

2, water pipe internal lining pipe according to claim 1 is characterized in that, assistant tool is established steel wire tightrope (4) and the flake down winch (5) of taking over cover (6) by the fag end end and formed.
