H-shaped hollow anti-slide pile

Abstract

The invention discloses an h-shaped hollow anti-slide pile which comprises a front pile and a rear pile. A cross beam is connected between the front pile and the rear pile, the front pile comprises afirst pile front end and a first pile rear end, a first hollow hole is formed between the first pile front end and the first pile rear end, and the rear pile comprises a second pile front end and a second pile rear end. A second hollow hole is formed between the second pile front end and the second pile rear end, a front pile protruding block is arranged at the position, close to the cross beam, of the front pile, a rear pile protruding block is arranged at the position, close to the cross beam, of the rear pile, and the front pile protruding block and the rear pile protruding block are both located below the cross beam. The bottom of the front pile and the bottom of the rear pile penetrate through a sliding belt and are located in a sliding bed, the top of the front pile and the top of the rear pile are located in a sliding body, first steel bars are embedded in the front pile, and second steel bars are embedded in the rear pile. The h-shaped hollow anti-slide pile has the beneficialeffects that the soil arch effect of soil between piles is brought into full play, and supporting of the anti-slide pile to landslides is better facilitated.

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
