A method and construction tool for removing tie rods in soil

Abstract

The invention discloses a construction tool for removing tie rods in the soil, which comprises a water supply unit and a hollow pipe. The water supply unit includes a high-pressure water supply device and a high-pressure pipeline connected to the water outlet. Connected, the inner end of the hollow tube is used to align the surrounding soil of the tie rod in the soil. The port at the inner end of the hollow tube is set as a flat water outlet. The inner end of the hollow tube is also connected with a curved plate of Luoyang shovel structure. The curved plate adopts a single-layer structure or a double-layer structure with a cavity. The inner end port of the hollow tube is connected with the cavity inlet of the double-layer structure, and the cavity outlet is an arc-shaped spout arranged along the arc of the curved plate. The invention also discloses a method for dismantling the tie rods in the soil. Using the pressure of high-pressure water, the soil around the tie rods in the soil is washed away, so that a gap is formed around the tie rods in the soil, and the constraint of the outer soil body on the tie rods in the soil is removed, and then the soil body is used to remove the tie rods. External force pulls out the pull rod in the soil. The method is simple, convenient, easy to operate, low in cost, high in efficiency and high in success rate.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a method and a construction tool for removing tie rods in the soil. Background technique [0002] In recent years, prestressed anchor rods and soil nails, as a kind of soil tie rods in the rock and soil field, have been widely used in urban construction, especially in urban foundation pit support, and these soil tie rods have not been used after construction. Remove it in time. In this way, in the subsequent construction and development process of urban underground subways, pipe gallery support piles, etc., it is often encountered that concrete metal tie rods embedded in the soil during the original construction will form obstacles, which will bring troubles to the later construction and increase costs. . [0003] In order to solve this kind of problem, there are removable bolts on the market, that is, the metal rods embedded in the soil are removed when the su...
