Trenchless pipeline inner wall cleaning device and pipeline inner wall cleaning method

Abstract

The invention discloses a trenchless pipeline inner wall cleaning device and a pipeline inner wall cleaning method. The trenchless pipeline inner wall cleaning device comprises a shell, a stretching mechanism is arranged on the surface of the shell, a cleaning mechanism is arranged at the top of the stretching mechanism, one side of the cleaning mechanism communicates with a liquid conveying pipe,the end, away from the cleaning mechanism, of the liquid conveying pipe penetrates into an inner cavity of the shell, a transmission mechanism is arranged on the left side of the shell, a driving device is arranged on the left side of the transmission mechanism, and a limiting mechanism is arranged at the bottom of the transmission mechanism. According to the trenchless pipeline inner wall cleaning device, during actual use, a user can control the stretching mechanism and the cleaning mechanism to be unfolded and folded according to the size of a pipeline; therefore, the size corresponding tothe pipeline can be adjusted, the requirement for cleaning the pipelines of different sizes is met, the cleaning range of the pipelines is enlarged, the cleaning efficiency is improved, the integrating degree between the cleaning device and the pipelines can be improved, the cleaning effect is improved, and use by the user is facilitated.

Description

technical field [0001] The invention relates to the field of non-excavation technology, in particular to a device for cleaning the inner wall of a non-excavation pipeline and a method for cleaning the inner wall of the pipeline. Background technique [0002] Trenchless refers to the use of various geotechnical drilling equipment and technical means to excavate a very small part of the surface (generally refers to small-area excavation at the entrance and exit) through guided and directional drilling. And the new construction technology for repairing various underground pipelines will not hinder traffic, will not damage green land, vegetation, will not affect the normal life and work order of shops, hospitals, schools and residents, and solve the traditional excavation construction on residents' lives Disturbance, damage and adverse effects on traffic, environment, surrounding building foundations, thus having high socio-economic effects. [0003] During the use of the pipel...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a trenchless pipeline inner wall cleaning device and a pipeline inner wall cleaning method, which have the advantages of being able to fit with different shapes of pipelines and can adjust the size, and solve the problem that the cleaning device cannot Adjust according to the shape of the inner wall of the pipe, the fit is low, and it is impossible to cover everything when cleaning, the cleaning effect is not good, the cleaning efficiency is low, the inner diameter of the pipe is not the same, and the cleaning device cannot be adjusted according to the size of the pipe. Furthermore, when cleaning, it is easy to be limited by the size of the pipeline, thereby reducing the cleaning range and reducing the cleaning efficiency
