Installing method of foundation pit slope support soil nails
The invention discloses an installing method of foundation pit slope support soil nails. The installing method comprises the following steps that firstly, a plurality of nylon wires are arranged in a criss-cross manner so that the positions of a plurality of lines of nailing points where the soil nails need to be nailed on a foundation pit slope can be determined; secondly, an electric hammer is used for pressing and conveying the soil nails into a foundation pit slope soil layer till the exposure length of the soil nails is 400-600 mm; thirdly, a plurality of temporary wood spring boards are laid in the slope surface direction perpendicular to the foundation pit slope, and an operator stands on the temporary wood spring boards to press and convey the soil nails till the exposure length of the soil nails is 50-150 mm; and fourthly, a steel wire net is installed on the slope surface of the foundation pit slope, then concrete is sprayed into the steel wire net, finally, the temporary wood spring boards are dismounted, and concrete curing is carried out. According to the installing method, due to the fact that the electric hammer is used for carrying out soil nail anchor rod installing, an anchor rod pressed in the soil layer moves rapidly, the installing time is shortened, and the technical problems that when the soil nails are pressed or hammered manually one by one, diseconomy is caused, moving is not convenient, and labor intensity is high are solved.
