A kind of h-shaped hollow anti-slide pile

Abstract

The invention discloses an h-shaped hollow anti-sliding pile, which comprises a front pile and a rear pile, a beam is connected between the front pile and the rear pile, and the front pile includes a pile front end and a pile rear end. A hollow hole 1 is provided between the front end 1 of the pile and the rear end 1 of the pile. The rear pile includes a front end 2 and a rear end 2 of the pile. Hole 2, the front pile is provided with a front pile bump near the crossbeam, and the rear pile is provided with a rear pile bump near the crossbeam, and both the front pile bump and the rear pile bump are located Below the crossbeam, the bottoms of the front pile and the rear pile run through the slide belt and are located in the slide bed, the tops of the front pile and the rear pile are located in the slide body, and a steel bar is embedded inside the front pile. , the inside of the back pile is embedded with two steel bars. Beneficial effects: the soil arch effect of the soil between the piles is fully brought into play, and the anti-slide pile is more conducive to supporting the landslide.

Description

technical field [0001] The invention relates to the technical field of civil engineering and geotechnical engineering, in particular to an H-shaped hollow anti-slide pile. Background technique [0002] In the field of landslide control, anti-slide piles are widely used in landslide support, but due to the shortcomings of ordinary anti-slides such as insufficient bending resistance and low overall stiffness. The predecessors have taken different ground measures to improve the anti-sliding performance of the anti-slide pile, such as increasing the cross-sectional area of ​​the single pile or making the pile body into a trapezoid to increase the compressive performance of the pile body, but this increases the strength of the concrete. The dosage increases the project cost. [0003] However, when dealing with large landslides, the shortcomings of the single pile's insufficient anti-sliding ability are undoubtedly exposed. The predecessors used anchor cable anti-slide piles and...

AI Technical Summary

Problems solved by technology

At present, most anti-slide piles are solid piles with circular or rectangular cross-sections. On the one hand, the amount of concrete is increased and the cost of the pile is increased; on the other hand, there is no differential analysis of the stressed parts of the pile. A certain amount of waste of building materials
