Anti-sliding buttress for underground climbing pipe

Abstract

The invention discloses an anti-sliding buttress for an underground climbing pipe. The anti-sliding buttress is composed of a concrete buttress, a pipe and a pipe socket. The pipe socket simultaneously achieves the pipe limiting effect. The problem that friction force generated between soil and a pipe is not large enough to resist sliding force caused by the self weight of the pipe in the traditional pipe climbing process is solved. The problem that project investment is large due to the fact that pipe top earthing thickness is large is avoided on the premise that safe pipe climbing can be achieved, and therefore the project requirement for large-slope-ratio, long-distance and shallow-buried pipe climbing can be met. By evenly arranging the anti-sliding buttresses, the climbing pipe stressis reasonable, and the engineering accident that pipes are disconnected at a joint due to the self weight of the climbing pipe or pressure of water inside the pipe can be effectively prevented from happening.

Description

technical field [0001] The invention relates to prevention of pipeline slippage when buried pipelines climb slopes in municipal and general industrial and civil construction projects, in particular to an anti-slip support pier used for underground slope-climbing pipelines. Background technique [0002] Buried pipeline climbing is a common engineering situation. When the friction between the pipeline itself and the soil is not enough to resist the sliding caused by the pipeline's own weight, various methods need to be adopted to improve the pipeline's anti-slip capability. Traditional anti-slip methods for buried pipelines generally include reducing the climbing angle of the pipeline and increasing the thickness of the top cover soil of the pipeline. On the one hand, these methods limit the maximum climbing angle of the pipeline and cannot fully meet the complex and diverse engineering requirements. Increasing the thickness of the pipeline covering soil will face huge enginee...

AI Technical Summary

Problems solved by technology

The method of improving the anti-slip ability of the pipeline by increasing the thickness of the top covering soil of the pipeline increases the frictional resistance between the pipeline and the soil, but this method greatly increases the construction period and manpower, the effect is not obvious enough, and the thickness of the covering soil cannot be increased infinitely
