Anti-slide pile on slope

Abstract

This is an anti-slide pile, its section form is as V word, its angle between two surface 10-150 deg. When the soil body has partly deformed, the soil of slide layer would move along the two outside faces of the V form pile its density become more and more, and move forward the space between two form piles, in the slope body may partly form arching, then the part's stable be strengthened, and whole the slope body are more stable, then the moisture content in the slide layer may be removed out between the space quickly, in the same time, the V-form surface may resolve the pressure of the slide pile: effetely.

Description

technical field [0001] The invention relates to a slope body anti-sliding pile for reinforcing side slopes. Background technique [0002] Landslides are a common unfavorable geological phenomenon in construction projects. Landslides should be avoided as much as possible in the process of project site selection. Various landslide problems require effective engineering measures to control them. [0003] Setting anti-sliding retaining structures to prevent slope sliding is the most effective treatment method in current engineering, among which anti-sliding piles are the most widely used. The basic anti-slide principle is to set a series of piles at appropriate positions in the landslide zone, these piles pass through the slide zone and enter the lower stable foundation, and use the anchorage section of the piles to prevent the slide of the slope. Generally, in the design principle of anti-slide piles, the properties of soil before and after embedding anti-slide piles are cons...

Problems solved by technology

[0004] Since the current design principles of anti-slide piles do not take into account the characteristic that the soil can be arched, and fail to organically combine the shape of the pile with the natural characteristics of the soil, most of the anti-slide piles are designed as cylinders, which are relatively large compared to the entire landslide body. , whether it is the arrangement of the anti-slide piles, the arrangement density, or the strength of each pile is considered separately, only when the arrangement of the anti-slide piles reaches a very high density can it play an anti-slip effect; cylindrical anti-slide piles When functioning, it must have very high strength to withstand the huge shear and pressure of the sliding layer, and the cylindrical structure can only increase its compressive strength by increasing the cross section, so the existing anti-slide piles are usually very weak. Coarse, some with a diameter of up to several meters, which will undoubtedly increase the cost of money, the amount of work is large, the cost of treatment is high, and the treatment effect is low
