Traction-type non-excavation pipeline repairing method

Abstract

The invention provides a traction-type non-excavation pipeline repairing method and relates to a construction device. The construction device comprises a reducing pipe, the inner diameter of the reducing pipe reduces gradually in the axial direction of the reducing pipe, the end, where the minimum inner diameter is located, of the reducing pipe is a reducing outlet end, and the inner diameter of the reducing outlet end is smaller than that of a pipeline needing to be repaired; the method comprises the following specific steps: 1, selecting a PE pipe with the outer diameter larger than that of the pipeline needing to be repaired and the length larger than that of the pipeline needing to be repaired; 2, arranging the construction device adjacent to the inlet end of the pipeline needing to be repaired, placing the PE pipe at a reducing inlet end of the reducing pipe in the construction device, and arranging the PE pipe to be matched with a traction machine; 3, starting the traction machine, and keeping the traction machine pulling the PE pipe to move in the direction of the location of the pipeline needing to be repaired and pass through the reducing pipe and the pipeline needing to be repaired in sequence. By means of the traction-type non-excavation pipeline repairing method, a non-excavation technique is used, the long-distance pipeline needing to be repaired is repaired conveniently and rapidly, meanwhile, the cost of the used technique is low, and the effect is good.

Description

technical field [0001] The invention belongs to the technical field of pipeline repair, and in particular relates to a traction-type non-excavation pipeline repair method applied to long-distance pipeline repair and large-area pipeline damage. Background technique [0002] Urban drainage pipe network is an important part of urban infrastructure design. The management of urban drainage pipe network is of great significance to the protection of urban environment, urban construction and economic development, and it is also an important symbol to measure urban modernization management. It is an important guarantee facility for water pollution control and drainage and waterlogging prevention. However, at present, there are problems that the detection of urban drainage pipes and canals is not yet popular, maintenance equipment is backward, and there is only a small amount of exploration in the repair of pipes and canals, which mainly relies on foreign technology. The maintenance, ...
