Abstract

The invention relates to a method for installing a slope reinforcing mesh, which comprises the steps of prefabricating a plurality of reinforcing meshes in advance, and then installing the slope reinforcing mesh in a framing and hoisting mode, and simultaneously, arranging a hanging rod and hoisting the reinforcing mesh through the hanging rod instead of directly hoisting the reinforcing steel, so that the condition that the reinforcing steel is possibly bent or broken or iron wires for binding the reinforcing steel are separated or broken when the reinforcing steel is directly hoisted is effectively avoided.

Description

A kind of installation method of slope reinforcement mesh

technical field

The invention relates to the technical field of slope protection construction, in particular to a method for installing slope reinforcement mesh sheets.

Background technique

Slope protection is very common in outdoor construction, and its function is to limit the weathering, spalling or destruction of rock and soil on the slope and the collapse of dangerous rocks. The support method of spraying anchors and hanging nets is a relatively common one in slope protection. The support method of spraying anchors and hanging nets mainly includes the following steps: placing holes on the slope, drilling, installing anchors, anchor grouting, installation Steel mesh and shotcrete. In the prior art, in the step of installing the steel mesh, it is necessary to build a steel pipe frame platform first, and then workers bind the steel bars on the slope through the platform. Workers are cumbersome, time-consuming, and dangerous to operate during the construction process; moreover, the spacing of the steel mesh sheets and the straightness of the steel bars cannot be guaranteed during the binding process.

Contents of the invention

The purpose of the present invention is to provide an installation method for slope reinforcement mesh for workers in the prior art to install slope protection reinforcement mesh, which is troublesome and time-consuming to operate, and the quality of the reinforcement mesh is difficult to guarantee.

In order to achieve the above object, the present invention provides a method for installing slope reinforcement mesh, comprising the following steps:

S1: Bind a certain number of steel mesh pieces according to the area to be protected on the slope;

S2: setting a hoisting ring or hoisting hook at the top of each vertical steel bar on each piece of steel mesh;

S3: Insert a suspender in the hoisting ring or hoisting hook of one of the steel mesh sheets, and lift the steel mesh sheet to the slope by lifting the suspender;

S4: Take down the suspender, insert it into the hoisting ring or hoisting hook of the next steel mesh sheet, and then perform hoisting, and repeat this operation until all the steel mesh sheets are hoisted.

The present invention adopts the aforementioned technical solution, by prefabricating several pieces of steel mesh in advance, and then realizing the installation of the slope steel mesh by means of framing hoisting, at the same time, by setting the boom and lifting the steel mesh through the boom instead Direct lifting of the steel bars effectively avoids bending or breaking of the steel bars that may be caused by direct lifting of the steel bars, or causes the iron wires binding the steel bars to fall off or break. Time-consuming, and difficult to guarantee the quality of the steel mesh, the invention realizes the installation of the slope steel mesh by means of framing hoisting, without the need to build a steel pipe frame platform, the construction operation is simple, more time-saving, and the steel mesh is prefabricated in advance, Its quality can be guaranteed.

Further, in step S2, the hoisting ring or hoisting hook is formed by welding the C-shaped lifting lug to the top of the vertical steel bar, and the hoisting ring or hoisting hook is formed by welding, which is easy to implement and easy to construct.

Further, in step S2, the lifting ring or the lifting hook is formed by bending the top end of the vertical steel bar. This method of forming the lifting ring or the lifting hook is also easy to implement and easy to construct.

Further, the suspender is made of channel steel with high rigidity to avoid deformation during hoisting.

Further, in steps S3 and S4, there are two lifting points on the boom, which are symmetrically arranged at both ends of the boom, so as to ensure that the boom is in a horizontal state after lifting, so as to ensure stable hoisting of the steel mesh.

Further, in steps S3 and S4, the steel mesh sheet is hoisted by a crane, and the hoisting by a crane makes the hoisting process convenient and efficient.

Further, the steel mesh sheet adopts Φ8 steel bars of HPB300, and the horizontal and vertical distances are both 15cm.

Further, the horizontal dimension of each steel mesh sheet is 3m, and the longitudinal dimension is 10m.

Further, the length of the suspender is greater than or equal to 3m, ensuring that the suspender can be in contact with each hoisting ring, ensuring that the weight of the steel mesh sheet is sufficiently dispersed to be loaded on the suspender, and preventing local stress on the suspender during the hoisting process concentrated and deformed.

Further, the channel steel is No. 10 light channel steel, and the light channel steel is selected to reduce the lifting weight.

Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention realizes the installation of the reinforcement mesh of the slope by means of framing hoisting, without the need to build a steel pipe frame platform, and the construction operation is simple and time-saving, and the reinforcement mesh is advanced Prefabricated, its quality can be guaranteed.
