Anchor cable sleeving and taking machine adopting shield method for tunnel crossing anchor cable construction

Abstract

The invention relates to an anchor cable sleeving and taking machine adopting a shield method for tunnel crossing anchor cable construction. The anchor cable sleeving and taking machine comprises a soil layer, a first spring and balls. An anchor cable penetrates through the soil layer. A first base is arranged on one side of the soil layer. Supporting leg grooves are formed in the bottoms of the two sides of the longer side of the first base. Supporting legs are rotatably connected in the supporting leg grooves. Blocking rod grooves are formed in one side, close to the supporting legs, of thefirst base. The anchor cable sleeving and taking machine adopting the shield method for tunnel crossing anchor cable construction is provided with shearing frames. When an anchor cable groove completely sleeves the anchor cable at a tunnel construction site, a hydraulic motor injects hydraulic oil through a first oil groove, so that the hydraulic oil pushes a top plate to move outwards towards a top plate groove, and the top plate drives the shearing frames to move towards the anchor cable. When the shearing frames on the upper and lower sides move simultaneously towards the anchor cable, shearing force is formed between the shearing frames to shear the anchor cable, and meanwhile, the shearing frames prevent the anchor cable from moving out of the anchor cable groove, the anchor cable isdirectly taken out through an anchor cable sleeve, and grouting or injection filling is avoided.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an anchor cable lasso machine for shield tunnel crossing anchor cable construction. Background technique [0002] Shield method tunnel construction refers to the use of a shield machine to control the excavation surface and surrounding rock from collapse and instability while carrying out tunnel excavation and slag removal, assembling segments in the machine to form a lining, and implementing grouting behind the wall. In the method of constructing the tunnel without disturbing the surrounding rock, during the construction of the tunnel, when it is necessary to pass through the anchor cable area, in order to prevent the anchor cable from hindering the shield machine, the anchor cable needs to be taken out. [0003] At present, there are various types of anchor cable pulling machines, which are used to reduce labor intensity, improve work efficiency, and increase the us...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of anchor cable sheathing machine for shield tunnel crossing anchor cable construction, to solve the above-mentioned background technology. The anchor cable is taken out by grouting or filling to increase the friction between the anchor cable and the anchor cable casing. The work efficiency of the anchor cable lasso machine is low, and when the existing anchor cable lasso machine drills into the soil layer, the anchor cable lasso machine base needs to be stabilized, and the anchor cable lasso machine base is fixed, which is inconvenient to use The problem
