A non-excavation overall repair method suitable for rainwater pipes

Abstract

The invention provides a non-excavation integral repairing method for a rainwater connection pipe. The non-excavation integral repairing method for the rainwater connection pipe comprises the following steps that S1, dredging and pretreatment are conducted on the rainwater connection pipe to be repaired; S2, a repairing material is manufactured according to the dimension of the rainwater connection pipe to be repaired; S3, natural curing resin is prepared; S4, the repairing material is treated before being mounted; S5, the repairing material is mounted in a pipeline; S6, pressurizing attachment and pressure stabilizing solidification are conducted; and S7, end treatment is conducted. According to the non-excavation integral repairing method for the rainwater connection pipe, a non-excavation integral repairing scheme for the small-diameter rainwater connection pipe is designed, and the construction quality is guaranteed while the construction cycle is shortened and the construction cost is reduced.

Description

technical field [0001] The invention belongs to the field of municipal engineering, and in particular relates to a non-excavation integral repair method suitable for rainwater connecting pipes. Background technique [0002] In the past, in cities and industrial areas, the repair of rainwater pipelines buried under roads for road surface rainwater drainage can only be done by excavation due to the small diameter of the pipelines. The road surface needs to be excavated, which is labor-intensive and time-consuming. In cities, this construction method is becoming more and more difficult, and the pressure on urban traffic is too great. With the improvement of science and technology, in recent years, the overall repair technology such as hot water curing and partial repair technology such as spot repair have been used to repair the rainwater connecting pipe. However, considering the vertical arrangement of the rainwater connecting pipe and the main pipe and the short length of the...

Problems solved by technology

[0002] In the past, in cities and industrial areas, the repair of rainwater pipelines buried under roads for road surface rainwater drainage can only be done by excavation due to the small diameter of the pipelines. The road surface needs to be excavated, which is labor-intensive and time-consuming. In cities, this construction method is becoming increasingly difficult and puts too much pressure on urban traffic

With the improvement of science and technology, in recent years, the overall repair technology such as hot water curing and partial repair technology such as spot repair have been used to repair the rainwater connecting pipe. However, considering the vertical arrangement of the rainwater connecting pipe and the main pipe and the short length of the pipe, the Although the above method solves the problem that the large excavation of the road surface affects the traffic, the repair method of hot water solidification occupies the main well and the road on the same side of the repair pipe due to the arrangement of the rainwater pipes, and the construction time is relatively long. , the general curing time is about 8-10 hours (the construction time is about 24 hours), and there are many construction equipments, which require hot water boilers, generators, air compressors, etc., which also have a great impact on traffic. In addition, due to the particularity of rainwater pipes, The length of a single construction is short and the construction cost is relatively high; although spot repairs occupy a small area of ​​the road, the construction time is relatively short, the general curing time is 2-3 hours (the construction time is about 8 hours), and the construction equipment is less. A small amount of equipment such as small air compressors, but spot repairs cannot meet the overall repair needs of pipelines
