Description

Combined type pipeline lining hose

Technical Field

The utility model relates to a belong to interior bushing pipe and be used for repairing the material of pipeline during each inside lining hose of use. The main fields are trenchless repairing pipeline lining of the pipeline and lining of a newly-built pipeline.

Technical Field

There are tens of thousands of underground pipes for civil and industrial use. These pipes include water pipes, sewage pipes, storm water drainage pipes, and professional transportation pipes. Because these pipes are mostly installed underground, they are often subjected to mechanical stress from the environment and various chemical corrosions resulting in damage to the pipes. For example, pipes may be subject to degradation over time, corrosion of fluids within the pipe, ambient environmental factors such as: surface water, etc. All of these factors have, over time, led to the development of holes, cracks and other problems requiring repair to prevent leakage of the fluid being transported within the pipe, for which conventional solutions have involved digging out the problem pipe and replacing it with a new one. But there are trillions of pipe lengths around the world, this solution is too expensive. Moreover, some pipes are located directly beneath streets or other facilities and if they are to be excavated, they can interfere with public order and require restoration after replacement is complete. In order to solve the problems of the conventional methods, the trenchless repairing of the pipe lining has become a very prosperous industry in recent years.

The most widely used method in many methods of repairing underground pipelines is to install a lining on the inner wall of the pipeline, and the lining is used for isolating the medium from the original pipeline, which is proved to be a very effective method through practice. Such as the technique of lining deformed plastic pipes, the technique of curing lining resin-impregnated hoses, etc., which are widely adopted at present. The plastic pipe deforming technology is that after the cross section of the plastic pipe is temporarily reduced, the plastic pipe is inserted into the pipe to be repaired, and the outer wall of the plastic pipe is made to adhere to the inner wall of the original pipeline by means of the elasticity of the plastic pipe or the re-rounding after applying pressure inside the lining pipe. One type of resin impregnated hose is a hose comprising an inner layer coated with a first layer of resin and an outer layer which is not sprayed with resin. The outside of the inner lining hose is sprayed with a second layer of resin. And then inserting the hose into the original pipeline, rounding the lining pipe by utilizing compressed air, and connecting the lining hose with the contact surface of the inner wall of the original pipeline after the resin is cured. And the other method is that resin is filled into the hose soaked with the resin, then the resin is extruded out to enable the inner surface to be uniformly coated with a layer of resin, one end of the hose is fixed at the inlet end of the original pipeline and then is turned over through compressed air or water, the side with the resin on the inner surface is turned over and then is contacted with the inner wall of the original pipeline, and the lining layer is formed after the resin is cured.

Although the above lining techniques are widely used at present, the selection of the specific types of lining pipes is not many, and various lining pipes have some problems in practical use, the most concentrated problem is that the lining pipes must be processed into lining pipes according to the inner diameter of the original pipeline before being lined into the original pipeline, and then enter the original pipeline after being deformed, if the inner diameter of the original pipeline is changed slightly, the lining pipes cannot be changed according to the caliber of the original pipeline, for example, a plurality of sections of pipes to be repaired spliced with different calibers need lining (mainly concrete prefabricated pipes), the selection of the outer diameter of the manufactured lining pipes can be only selected according to the smallest inner diameter of the original pipeline, and conversely, the lining pipes are difficult to be inserted into the pipes to be repaired, so that gaps exist between the pipes with large calibers and the lining pipes, and the lining pipes can be damaged after premature fatigue under the repeated action of pressure after the gaps are too large, if the liner pipe adopts a large caliber to-be-repaired pipe, the difficulty of inserting the pipe is high, and the overlarge liner pipe cannot extend in the to-be-repaired pipe at the small diameter, so that the liner pipe is damaged too early due to overlapping. Therefore, the lining pipe which is suitable for a large-caliber pipe and can be completely opened under the condition of a small pipe is required to be solved by the pipeline repairing industry.

Disclosure of Invention

The utility model discloses a modular pipeline inside lining hose purpose is just proposed for solving this technical problem.

In order to achieve the above purpose, the utility model is realized by the following technical scheme:

a combined type pipeline lining hose is composed of a hose body layer 1; the anchoring pile comprises an anchoring pile body 2, a coupling end 3 and the like, wherein the pipe body layer 1 is a main body, the anchoring pile body 2 and the coupling end 3 are auxiliary main bodies to realize functions, and are made of soft plastics into a whole.

One side of the pipe body layer 1 is a smooth surface which is used as the inner surface of the lining hose, and the other side is a continuous independent convex and evenly distributed anchoring pile 2.

One side of body layer 1 is coupling end 3 and the other side is the thickness of body layer 1 and has an arc that is higher than the thickness of body layer 1/3.

The hose can be formed by combining a single main body or a plurality of main bodies, wherein the lining hose combined by the single main body is formed by mutually inserting the two side edges of the main body, and the combination of the plurality of main bodies is formed by transversely serially inserting the plurality of single main bodies.

Advantageous effects

An object of the utility model is to provide an applicable inside lining hose that has the pipe diameter to have under the different situation in same pipeline. The two sides of the lining hose produced according to the invention adopt different coupling modes, the lining hose is formed by coupling the two sides outside the pipeline to form the lining pipe, therefore, the lining pipe is in a sheet shape before being formed, which provides great convenience for transportation to the site, and the lining hose can be wound into a cylinder shape for transportation to the site, thereby saving transportation space. Due to the adoption of the combined type, the structure of one single main body is applicable to various pipelines, the single main body can be produced in a standardized manner, different pipeline diameters can be combined by the single main body at will, and the cost of various complex molds for producing liner tubes with various specifications can be saved. In addition, due to the coupling ends at the two sides of the pipe body layer 1, the pipe diameter size of the lining hose on the section has room for adjustment, so that the size precision on the section of an outer pipeline needing the lining is not important, therefore, the size on the section of the lining layer can be changed along with the size change on the section of the outer pipeline, and the quality of the lining is greatly improved. The invention also increases a selection range on the variety of the lining pipes of the trenchless lining repair pipeline, and has obvious economic benefit.
