Embodiment 1

[0041] The scheme of embodiment one is:

[0042] A prefabricated pile, which includes: electroosmotic unit components 1 and concrete piles 2, the number of electroosmotic unit components 1 is multiple groups, and the intervals are distributed on the concrete piles;

[0043] The electroosmosis unit component 1 includes: a cathode component 1-1, an anode component 1-2;

[0044] The cathode component 1-1 includes: a cathode metal tube 1-1-1, holes are provided on the surface of the cathode metal tube 1-1-1, and filter materials are provided inside the openings of the cathode metal tube 1-1-1;

[0045] The anode component 1-2 includes: an anode metal tube 1-2-1;

[0046] The cathode metal tube 1-1-1 and the anode metal tube 1-2-1 are arranged on the outer surface of the concrete pile 2, and the cathode metal tube 1-1-1 and the anode metal tube 1-2-1 of each group are spaced apart a certain distance;

[0047] The distance L1 between the cathode metal tube 1-1-1 and the anode met...

Embodiment 2

[0074] Embodiment two, in landslide treatment area, landslide generally occurs after heavy rain, and its reason is, rainwater infiltrates, causes soil body to be soft; Therefore, the pile of embodiment one can be used as anti-slide pile, one is that pile body can be used The second is to use it to extract and discharge the water under the pile (especially the infiltration of rainwater), and the third is to gather the soil near the anode tube, which improves the strength of the soil.

[0075] Specifically, its construction steps are as follows:

[0076] First, calculate the possible sliding surface according to the numerical simulation software;

[0077] Second, design and arrange the anti-slide piles according to the calculation results of the numerical simulation software: the distance between adjacent piles is greater than or equal to L2, that is, to ensure that the electroosmotic unit components between adjacent piles avoid mutual interference; the anti-slide piles slide de...

Embodiment 3

[0079] Embodiment 3. For the pile body in Embodiment 1, all electroosmosis unit components are connected in parallel through a set of wires (positive and negative pole lines). When electrified, all electroosmosis unit components work at the same time.

[0080] However, in actual engineering, the moisture content of soil is always changing. Therefore, in order to more accurately control the moisture content of different soil layers of the soil, all electroosmotic unit components use an independent set of wires (positive and negative wires) to communicate with the DC power supply; The water content of each layer of the body is used to control which electroosmotic unit components of the prefabricated pile work and which do not work.

Abstract

The invention relates to a manufacturing method of an anti-slide pile and a construction method for preventing and treating a landslide by using the anti-slide pile. The key points of design are as follows: firstly, a reinforcement cage is manufactured, a threading pipe is bound on the reinforcement cage, and a wire penetrates into a wire pipe; a vertical water pumping pipe and a connecting jointis bound on the reinforcement cage; secondly, an outer formwork is installed, specifically, a cathode metal pipe and an anode metal pipe serve as an outer formwork of a pile foundation, a punching area is formed in the cathode metal pipe in advance, and a threaded connector protrudes out of the preset punching area of the cathode metal pipe; the interior of the threaded connector is hollow, and the size of the threaded connector is larger than that of the punching area; thirdly, concrete is poured, maintenance and demolding are conducted, and the cathode metal pipe and the anode metal pipe arereserved during demolding; and finally the electro-osmosis drainage integrated pile is obtained. By the adoption of the manufacturing method of the anti-slide pile and the construction method for preventing and treating the landslide by using the anti-slide pile, the water content in the slope soil body can be controlled, and the landslide is avoided.

Description

technical field [0001] The patent of the present invention relates to the field of geotechnical engineering and other fields, in particular to a method for manufacturing an anti-slide pile and a construction method for using the anti-slide pile to prevent and control landslides. Background technique [0002] "The siphon method gets rid of the deep groundwater in the landslide" (Shu Qun, Zhang Wende, China Western Science and Technology), "The Landslide Siphon Drainage Method", (Shang Yuequan et al., Journal of Engineering Geology). An effective method; the siphon has the characteristics of power-free realization of water body crossing transportation and automatic adjustment of the flow process by liquid level changes, and is very suitable for controlling the rise of landslide groundwater levels. However, for siphon suction, the maximum siphon lift of 10m and intermittent drainage may cause air accumulation at the top of the siphon, which restricts its application. [0003] ...
