Flow soil groove buried pipe anti-floating construction method

Abstract

The invention relates to a flow soil groove pipe burying anti-floating construction method which comprises the steps that when a pipeline is arranged in a groove and the groove is filled with flow soil, the initial filling height h0 is set; filling the groove with fluid soil according to the set initial filling height h0; and after the to-be-filled flow-state soil reaches the preset strength, the groove is filled with the flow-state soil again to embed the pipeline, and therefore anti-floating construction is completed. The layered pouring mode is adopted to prevent the pipeline from floating upwards and shifting in the flowing soil filling process, the proper initial filling height h0 is set to control the initial filling amount, the initial setting time is shortened, the construction progress is accelerated, and the problems that in the prior art, an anti-floating mechanism is additionally arranged, the construction difficulty is large, the construction progress is slow, and the construction cost is high are solved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to an anti-floating construction method for buried pipes in fluid soil trenches. Background technique [0002] In the Chinese patent with the publication number CN110566722A, a pipeline anti-displacement and anti-floating mechanism and a pipeline anti-floating construction method are disclosed, including a horizontal bar arranged parallel to the upper side of the pipeline, at least one set of diagonal bracing components, and at least Two sets of limit components, the two sets of limit components are movably installed on the bottom of the cross bar, and are respectively located on the opposite sides of the pipeline, one end of the two sets of limit components respectively abuts against the two opposite inner walls of the foundation pit . In this patent, the pipe is clamped and positioned by the limiting components arranged on both sides of the pipeline to laterally limit the pi...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the defects of the prior art, and provide an anti-floating construction method for buried pipes in fluid soil trenches, so as to solve the problem of increasing the construction cost by using the anti-displacement and anti-floating mechanism of the pipeline in the prior art to avoid the floating and offset of the pipeline. Difficulty, slow down the construction progress, increase the construction cost, affect the filling quality of the pipeline, increase the construction risk, etc.
