A kind of pipeline inner wall cleaning device used for interpenetrating pipeline repair

technical field

The present application relates to the field of pipeline repairing equipment, and in particular, to a pipeline inner wall cleaning device used for pipeline repairing by interpenetration method.

Background technique

The urban municipal pipe network system is an important part of urban infrastructure. With the continuous improvement of urbanization in my country, the length of the newly laid and updated municipal pipe network has exceeded 100,000 kilometers every year in recent years. The transformation of the existing urban pipeline network is an unavoidable problem in the process of urban development. If the method of excavation and replacement is fully adopted in the renewal process of the urban underground pipe network, not to mention the huge expenditure, the environmental problems, traffic problems and the impact on the residents' lives will be quite large. It is a strong requirement for urban construction and modern social life to adopt trenchless means to solve the problems in the pipeline network transformation and reduce the negative impact caused by the pipeline network transformation. The trenchless pipeline repair technology is to use the original pipe position resources and install the lining (new pipeline) in the existing pipeline without excavation or less excavation (only excavation of the working well). The pipeline is regenerated, and the service life of 3O to 50 years can be regained.

The folding lining intubation method is to use the HDPE lining pipe whose outer diameter is slightly larger than the inner diameter of the main pipe, and then reduce the HDPE pipe through multi-stage equal diameter or press "U" shape through deformation equipment, and bind it with fiber tape to make its section smaller than the main pipe. The inner section of the HDPE pipe is quickly penetrated into the repaired pipe by the tractor. Then rely on the HDPE pipe's own memory characteristics or by increasing the pressure and temperature to open it and restore it to the original pipe diameter, so that the HDPE liner pipe diameter rebounds and expands and is attached to the inner wall of the main pipe in an interference state, which is consistent with the old pipe wall. Close to form a composite structural material that combines anti-corrosion properties with the mechanical properties of the repaired pipeline. So as to achieve the purpose of restoring the use function of the main pipeline and prolonging the service life.

This repair technology has high requirements on the cleaning of the original pipeline. The original pipeline must be cleaned before the pipeline lining is repaired. At present, the most widely used method is high-pressure water flushing. The existing high-pressure water flushing method mainly adds a high-pressure nozzle at one end of the water pipe, and through the water supply of the water pump, the high-pressure nozzle sprays a high-speed water column to flush the inner wall of the pipe, but the area where the high-pressure spray is installed is limited, and the staff needs to adjust the water pipe at all times. The direction of the high-pressure nozzle is controlled by the rotation of the device, so as to achieve the purpose of cleaning the inner wall of the pipeline. This method will greatly consume the labor consumption of the staff, so that the cleaning efficiency of the inner wall of the pipeline cannot be guaranteed.

In the foundation pit, part of the waste liquid will remain in the pipeline, which will not only affect the construction environment, but also increase the cost of cleaning waste water and slag by the staff. The setting of the recovery device can extract most of the waste water and waste residue in time while the descaling mechanism and the high-pressure nozzle are working, which reduces the dispersion of waste water and reduces the difficulty of subsequent cleaning of waste water and waste residue.
