Embodiment Construction

[0019]The features of the present invention will be further described below in conjunction with the accompanying drawings and specific examples, and the given examples are only used to explain the present invention, and are not intended to limit the scope of the present invention. After reading the present invention, within the spirit and principle of the present invention, any modification, equivalent replacement and improvement should be included in the protection scope of the present invention.

[0020] The working principle of the present invention is: when the moisture content in the slope body is lower than the limit moisture content of the moisture sensor control switch, the moisture sensor control switch is automatically disconnected, the electroosmosis process is not carried out, and the slurry solidified in the bag will not The stable soil is anchored in the stable area; when the moisture content in the slope rises to the limit moisture content of the moisture sensor ...

Abstract

The invention discloses a side slope self-drainage electroosmosis anchor rod and a construction method thereof, and belongs to the technical field of rock-soil anchoring. The self-drainage electroosmosis anchor rod comprises two electric geotechnical bags, anchors, base plates and a siphon. Hollow tubes are sleeved with the electric geotechnical bags to extend to the bottoms, sleeve valves are fastened to reserved holes in the electric geotechnical bags, and the electric geotechnical bags are strapped to the hollow tubes externally through plastic clamps on the left sides and the right sides of bags. Slurry is solidified and anchored in a stable side slope, and the front sections of the electric geotechnical bags are anchored on the base plates by the anchors. A moisture inductive control switch is buried in soil of the slope surface, a solar battery is disposed outside the slope, and a positive pole, the moisture inductive control switch, the solar battery and a negative pole are sequentially connected in series through wires. A water suction tube is inserted into the hollow tube of the negative pole and is connected with a balance water discharge device on the slope surface through a connection elbow and a water discharge tube. A water inlet of the water suction tube is the same as a water outlet of the balance water discharge device in elevation. The side slope self-drainage electroosmosis anchor is ingenious in structure, has functions of anchoring, water discharging and solidification acceleration and is high in automation degree, and the construction method is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of rock and soil anchoring engineering, and in particular relates to a side slope self-drainage electroosmotic anchor rod and a construction method, which are mainly applicable to soft clay slopes, saturated soil slopes, and slope body reinforcement projects with high groundwater levels. Background technique [0002] my country is a very serious landslide disaster country, which often causes great losses to engineering construction and life and property. Most landslides are significantly affected by rainfall. The infiltration of rainfall into the slope reduces the strength of the soil, and the rise of the groundwater level caused by rainfall causes the buoyancy of the landslide body, the downward force increases, and the stability of the slope body is seriously reduced. Soft clay is widely distributed in the southeast coast of my country and the Pearl River Delta region. A large number of engineering cons...
