Electromagnetic drainage anti-slide pile and construction method thereof

Abstract

The application provides an electromagnetic drainage anti-slide pile and a construction method thereof, and belongs to the field of landslide prevention engineering. The anti-slide pile comprises hollow piles, gravel, anchor cable, coils, a controller, a moisture meter, a water pumping pipe and a portable water suction pump, wherein a second type of hollow pile is coaxially nested in a first typeof hollow pile, the gravel is filled between the two types of piles, and the gravel is squeezed into the first type of hollow piles by the anchor cables; the coils are wound on the outer wall of the water pumping pipe and is nested in the second type of hollow pile; the portable water suction pump is arranged at the top end of the water pumping pipe, the controller is arranged outside a slope andis respectively connected with the moisture meter, the coil and the high-frequency alternating-current power supply; when the water content of the soil body is larger than the limit water content, thecoil generates an alternating magnetic field to promote the water to enter the hollow pile, and the water pumping pipe and the portable water suction pump discharge water in the slope to the outsideof the slope; and otherwise, the coil is powered off. According to the anti-slide pile for monitoring and rapid drainage, the problem of instability caused by difficulty in drainage of a low permeability slope in a rainfall-rich area is solved, the structure is simple, the construction is easy, and the cost is greatly saved.

Description

technical field [0001] The application relates to the technical field of rock-soil anchorage, in particular to an electromagnetic drainage anti-slide pile and a construction method thereof. Background technique [0002] Landslides are one of the three major global geological disasters. They are widely distributed, occur frequently, are difficult to predict, and are expensive to manage. They often pose a major threat to people's lives and property. They have always been an important geological disaster issue of concern to countries all over the world. The occurrence and migration of groundwater are the main factors affecting slope stability, and the recharge mainly includes recharge at the trailing edge of the landslide body, rainfall infiltration on the slope surface, and reservoir (river) water level. About 90% of the catastrophic landslide disasters that have occurred worldwide in the past century are directly related to water, which is often said to be "nine out of ten sl...
