Embodiment Construction

[0022] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

[0023] The present invention provides a maintenance method for a pipeline, such as figure 1 and 2 As shown, the pipeline 1 includes an inner pipe 2 and a pipe sleeve 3 sleeved outside the inner pipe, the pipe sleeve 3 has defects, and the maintenance method includes: S1: the pipe sleeve 3 The length direction of the pipeline 1 is divided into a plurality of sockets 7 , and the plurality of sockets 7 are replaced in batches, so as to complete the maintenance of the pipeline 1 . Wherein, the pipeline can be in various reasonable forms, for example, it can be a water delivery pipeline, specifically, it can be a PCCP pipe (prestressed steel cylinder concrete pipe), a PCP p...

Abstract

The invention relates to the technical field of maintenance of large pipelines, in particular to a maintenance method of pipelines. The pipeline (1) comprises an inner pipe (2) and a pipe sleeve (3) sleeved outside the inner pipe (2), the pipe sleeve (3) has defects, and the maintenance method includes: S1: The pipe sleeve (3) is divided into a plurality of socket sections (7) along the length direction of the pipe (1), and the plurality of socket sections (7) are replaced in batches, thereby completing the repair of the pipe (1). maintain. The maintenance method of the pipeline reduces the maintenance cost of the pipeline by dividing the pipe sleeve into a plurality of sleeve sections and replacing them in batches.

Description

technical field [0001] The invention relates to the technical field of maintenance of large pipelines, in particular to a maintenance method of pipelines. Background technique [0002] At present, more and more water pipelines are used in large-scale water diversion projects in my country, such as PCCP pipes (prestressed steel cylinder concrete pipes), PCP pipes (prestressed reinforced concrete pipes), glass sand pipes, reinforced concrete pipes Circular pipes such as pipes and steel pipes are commonly used water delivery pipes in the prior art. However, due to design and construction quality defects, improper operation management and other reasons, pipe bursts have occurred in many water diversion projects, which seriously threatens the safe operation of water pipelines. [0003] Most of the PCCP pipe bursts are caused by defects such as broken wires in the twisted hoop prestressed steel strands on the high-strength concrete pipe core. The pipes with serious defects need to...
