Anti-slide pile with I-shaped cross section

Abstract

The invention relates to an anti-slide pile with an I-shaped cross section. The anti-slide pile with the I-shaped cross section is poured by reinforced concrete. Transverse width at the rear end of the anti-slide pile is larger than that of a common anti-slide pile with a rectangular cross section, so that post-pile soil arch effects are brought into full play, pile center distance between two adjacent anti-slide pile can be increased when the anti-slide piles are disposed on a plane, and the amount of the required anti-slide piles is reduced under the same landslide conditions to reduce cost. The rear end and the front end of the anti-slide pile are arc-shaped, stress concentration damaging the anti-slide pile is prevented from being generated at tips. The anti-slide pile can bear large slope pushing force has good bending resistance. The cross section area of the anti-slide pile is remarkably smaller that of the anti-slide pile with the rectangular cross section, so that concrete quantity and rebar quantity needed are reduced greatly, a large amount of concrete and rebar is saved, and cost is lowered. The anti-slide pile is small in construction section and simple and safe in construction, has promising popularization application prospect and facilitates mechanical construction.

Description

technical field [0001] The invention relates to a reinforced concrete anti-slide pile for slope engineering and landslide treatment engineering, in particular to an anti-slide pile with an I-shaped cross section, which belongs to the technical field of slope or slope stabilization. Background technique [0002] There are many ways to control slopes and landslides, among which setting anti-slide piles is a very widely used control scheme. The anti-slide principle of anti-slide piles is to drive the anti-slide piles below the sliding surface, and transmit the thrust of the slope body on the upper part to the lateral soil or rock mass below the piles through the pile body, relying on the lateral resistance of the lower part of the piles to bear The downward thrust of the slope or sliding body keeps the slope or landslide in balance or stability. [0003] In today's landslide and slope treatment projects, a single anti-slide pile has limited anti-slide ability compared to the e...
