An anti-slide pile structure with multi-area joint drainage function and its construction method

Abstract

The invention discloses an anti-slide pile structure with the multi-area combined drainage function and a construction method of the anti-slide pile structure. An anti-slide pile includes a lower pilebottom structure, an upper pile body structure and a reinforcement cage whole; the lower pile bottom structure and the upper pile body structure are connected as a whole through the reinforcement cage whole by a pouring method; the reinforcement cage whole includes an internal circular reinforcement cage and an external square reinforcement cage from inside to outside; the internal circular reinforcement cage and the external square reinforcement cage are connected as the reinforcement cage whole through connecting steer bars; the upper pile body structure includes an upper cross-shaped pilecore, an upper square pile wall, an inclined water collection hole and a right angle fan-shaped water storage space; and the lower pile bottom structure includes a lower square pile bottom and a drainage hole. The anti-slide pile structure with the multi-area combined drainage function is simple in structure, can be prefabricated or cast in situ, and very obvious effects are provided on effectively improving the bending and shearing resistance and drainage performance of an inclined side slope, and enhancing safety and stability of the side slope.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of geological disasters, in particular to an anti-slide pile structure with multi-area joint drainage function and a construction method thereof, especially for areas with frequent rainfall and high incidence of landslide disasters, and is suitable for slope engineering and landslide control engineering. Background technique [0002] Landslides are a serious geological hazard worldwide, and hydraulic effects such as rainfall, melting ice and snow, and reservoir water ups and downs are one of the most important external factors that induce landslide disasters. With the increasing frequency of human engineering activities, landslide geological disasters are becoming more and more frequent, causing more and more losses. In landslide prevention and control engineering, anti-slide piles are one of the most common engineering measures for landslide control. The main function of the anti-...

Problems solved by technology

Although there are many drainage anti-slide piles with improved drainage effects, they have defects such as cumbersome construction steps, poor integrity, poor drainage performance or limited functionality.

The document with application number 201811332042.X discloses a deformation self-adaptive drainage anti-slide pile for expansive soil slopes and its construction method. The elastic section is connected by a spring, which has poor integrity and reduced bending and shear resistance.

In addition, compared with the square pile, the round pile has a smaller bearing capacity and lower impact resistance; and the traditional siphon drainage technology only realizes slope drainage, and its function is relatively single
