An electromagnetic drainage anti-slide pile and its construction method

Abstract

The application provides an electromagnetic drainage anti-slide pile and its construction method, which belong to the field of landslide prevention and control engineering. The anti-slide pile includes: hollow pile, gravel, anchor cable, coil, controller, moisture meter, water pipe and portable water pump ;The second type of hollow pile is coaxially nested in the first type of hollow pile, and gravel is filled between the two types of piles. In the second type of hollow pile, the portable water pump is installed on the top of the water pipe, and the controller is placed outside the slope to connect with the moisture meter, the coil and the high-frequency AC power; when the moisture content of the soil is greater than the limit moisture content, the coil generates alternating The variable magnetic field promotes water to enter the hollow pile, and the suction pipe and portable pump drain the water in the slope to the outside; otherwise, the coil is powered off; The permeable slope is difficult to cause instability caused by drainage, 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...
