The urban municipal pipe network system is an important component of urban infrastructure, and as the urbanization process of China is continuously improved, the length of a newly laid, updated and reconstructed municipal pipe network exceeds 10 kilometers every year in recent years. The problem that the existing urban pipe network is not avoidable in the urban development process is solved by modifying the existing urban pipe network. If the excavation replacement means is adopted comprehensively in the updating process of the urban underground pipe network, the huge expense is not said, and the environmental problem, the traffic problem and the influence on the life of residents caused by the excavation replacement means are quite large. The problem in the pipe network transformation is solved by adopting a non-excavation means, and the reduction of the negative influence brought by the pipe network transformation is a strong requirement of urban construction and modern social life. The trenchless pipeline repairing technology is characterized in that under the condition of no excavation or few excavation (only excavation of a working well), original pipeline position resources are utilized, and a lining (a new pipeline) is installed in the existing pipeline in the related technology to regenerate the pipeline, so that the service life of 3O-50 years can be obtained again.

The folding lining pipe inserting method is characterized in that an HDPE liner pipe with the outer diameter slightly larger than the inner diameter of a main pipeline is subjected to multistage constant diameter reducing or U-shaped pressing through deformation equipment and is bound by a fiber adhesive tape, so that the cross section of the HDPE liner pipe is smaller than the inner cross section of the main pipeline, and the HDPE liner pipe is quickly penetrated into a repaired pipeline through a tractor. Then opening and recovering the HDPE pipe to the original pipe diameter by means of the self memory characteristic of the HDPE pipe or by increasing pressure and temperature, so that the pipe diameter of the HDPE liner pipe is rebounded and expanded and attached to the inner wall of the main pipe in an interference state and is tightly attached to the wall of the old pipe, and a composite structural material with the combination of the corrosion resistance and the mechanical property of the repaired pipe is formed. Thereby achieving the purposes of recovering the service function of the main pipeline and prolonging the service life.

Finally, the worker can cut off the extra length of the positioning strip 93 to prevent the strip from being wound into the turntable 31. By screwing the positioning bolt 96, the slip of the receiving ring 95 and the positioning strip 93 is restricted, so that the positioning strip 93 is held in a corresponding bent state, thereby holding the bellows 83 in a corresponding tensile bending device. In the process of rotating the turntable 31, each corrugated pipe 83 can be kept in corresponding filling, the corrugated pipes 83 are not easy to be rolled into the gap between the turntable 31 and the pipeline, and the normal extraction of waste water from the port of the corrugated pipe 83 in the moving process of the shell 1 is ensured.

As shown in fig. 1, a pulling rope 6 is fixedly connected to one side of the cover 12 away from the housing 1, and when the driving motor 52 and the water pump work, a worker can slowly pull the pulling rope 6, so as to drive the housing 1 to advance in the pipeline at a constant speed, and efficiently clean the inner wall of the pipeline, thereby reducing the labor consumption of the worker.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
