Extension arm type drainage slide-resistant pile and structural calculation method thereof

Abstract

An extension arm type drainage slide-resistant pile comprises a main pile column, and an extension arm and a drainage structure are arranged on the main pile column. The extension arms are arranged on the main pile column and located in front of and behind the main pile column, and the extension arms in front of and behind the main pile column achieve conversion from a sliding-blocking mode to a sliding-self-stabilizing-blocking mode between the sliding mass and the anti-sliding pile through development and utilization of the sliding mass. The drainage structure is arranged on the outer side of the main pile column and is formed by splicing pile core outer molds; a water inlet hole is formed in the outer wall of the drainage structure, a water storage cavity and a water vapor overflow pipe are arranged in the drainage structure, wherein the water vapor overflow pipe is communicated with the outside. According to the extension arm type drainage slide-resistant pile and the structural calculation method thereof, the positive effect of a landslide body can be developed and utilized, and the effect of the anti-slide pile is improved; water can be drained to overcome the stagnant water effect of the slide-resistant pile.

Description

technical field [0001] The invention relates to an anti-slide pile, in particular to an arm type drainage anti-slide pile and a structural calculation method thereof. Background technique [0002] Anti-skid and drainage are two measures often used in landslide control projects, which have a wide range of engineering application requirements. [0003] Anti-slide piles have experienced nearly a hundred years of application and development, but their structural design has always been around the central idea of ​​sliding-blocking. Under the guidance of this idea, various anti-slide pile structures have been developed. Pile bodies are always regarded as passive bearing bodies, and landslide bodies are disaster bodies. [0004] Water plays an important role in the development of landslide stability. However, its mechanism is complex and has not been fully revealed yet. Especially, the research and prediction of the stability of wading landslides is still a difficult problem. Dra...

Problems solved by technology

[0009] To sum up, the necessity of drainage and anti-slide in landslide treatment, the design concept of anti-slide pile structure is single, the treatment of anti-slide pile is often accompanied by the negative attribute water stagnation effect, the current drainage does not consider the drainage of stagnant water, anti-slide, Drainage projects go their own way and require a lot of investment
