Problems solved by technology

However, there is no relevant process guidance for the application and specific operation of the existing measures such as grouting reduction, pipeline reinforcement and reinforcement, and the specific handling is mostly based on the professional level, business experience and preference of the commanders. It is conducive to standardized operation and brings barriers to work handover and later maintenance
Moreover, the design of each link of the existing repairing pipe wall technology is still rough, and there is a lot of room for improvement in the speed and quality of on-site treatment
It is difficult to improve the repair efficiency,

Embodiment 1

[0080] Example 1: Description of the disease: Due to the combined action of summer rainfall and heavy vehicle loads on the road surface of a municipal project, the water level of the sand layer around the rainwater pipes has risen, further sand liquefaction has occurred, and the joints of rainwater pipes covered by the road surface Sand gushing occurred, and a small area of ​​funnel-shaped subsidence appeared on the road surface. Due to the uneven settlement of the foundation of the pipe bottom cushion, pipe body cracks, joint dislocation and other diseases occur. The opening height difference of the joint damage point is 400mm, the width of the joint is 600mm, and the sand leakage and sedimentation in some positions reach about 500mm. According to this development, the leakage Sand will form a sand gushing phenomenon, causing pipeline blockage, and even funnel-shaped settlement of the road surface, which affects the smooth drainage of the pipeline and the safe operation of the...

Abstract

The invention discloses a construction method for quickly solving sand leakage and gushing caused by dislocation of rain pipes and mainly relates to the field of municipal pipeline maintenance. The method comprises the steps of 1, arranging a dislocation pipeline wall rear panel; 2, conducting quick grouting on a fixed pipeline joint; 3, conducting quick grouting on a pipeline joint top; 4, reinforcing the pipeline joint and a pipeline bottom; 5, reinforcing a pipeline wall; 6, treating a pipeline leakage connector. The method has the advantages that water leakage, sand leakage and sand gushing at the position of the sewage (rain) pipe joint can be solved quickly, and the broken pipeline wall can be reinforced quickly.

Description

technical field [0001] The invention relates to the field of municipal pipeline maintenance, in particular to a construction method for rapidly controlling dislocation sand leakage and sand gushing of rainwater pipes. Background technique [0002] With the rapid development of my country's economy and the gradual improvement of various urban infrastructures, the increasing complexity of urban underground pipelines has become a trend in urban development. At the same time, higher requirements are put forward for the construction hardware standards and safety maintenance of underground pipelines and pipelines. The construction and operation of the sewage (rainwater) pipeline is affected by the surrounding soil, and the phenomenon of water leakage and sand leakage (sand inrush) at the interface of the sewage (rainwater) pipeline occurs. According to the development of this situation, local settlement of the municipal road surface will be caused, and the ground subsidence will b...
