A construction method for rapid repair of underwater pipeline leakage

Abstract

The invention provides a new construction method for rapid repair of underwater pipeline leakage. The rapid repair of underwater pipeline leakage is realized by installing a U-shaped steel sheath in the area to be poured in the leaking pipeline and pouring polymer resin concrete. It also provides The composition ratio of the polymer resin concrete: polymer resin matrix 12-20%, cement 7-15%, stone 30-40%, accelerator 0.07-0.12%, initiator 0.07-0.12%, and the balance is sand , the polymer resin matrix is ​​a composition of epoxy resin, polyurethane prepolymer, unsaturated polyester, and substituted ethylene; the polymer resin concrete can promote interface infiltration so as to obtain better wet bonding strength.

Description

A construction method for rapid repair of leakage of underwater pipelines technical field The present invention relates to underwater pipeline repair technical field, be specifically related to a kind of novel underwater pipeline leakage quick repair facility work method. Background technique [0002] The leakage of the underwater pipeline not only causes waste, but also causes environmental pollution. caisson tube for offshore oil platform For example, the caisson pipes will be corroded by seawater and perforated and leak, thereby causing pollution to the marine environment. If the leak site is In water, ordinary repair materials can be used to repair, but there is still no effective repair for pipelines under water. Methods, generally only take temporary methods to deal with, such as package coverage, this approach can only slow down the leakage, can not solve the leakage question. A rapid underwater leak repair technology is needed to solve the leakage problem ...

[0002] The leakage of underwater pipelines will not only cause waste, but also cause environmental pollution

Take the caisson pipe of an offshore oil platform as an example. The caisson pipe will be corroded by seawater and perforated to leak, thus polluting the marine environment.

If the leaking part is above the water, it can be repaired with ordinary repairing materials, but there is still no effective repairing method for the pipeline under the water, and generally only temporary methods are used, such as wrapping and covering, which can only slow down the leakage , does not solve the leakage problem

A rapid underwater leak repair technology is needed to solve the leakage problem of underwater pipelines and at the same time solve the safety hazard caused by the thinning of the pipe wall
