Embodiment Construction

[0044] Below in conjunction with accompanying drawing, a kind of structure and processing method of the existing anchor cable that cuts intrusion into station foundation pit scope of the present invention are described in detail:

[0045] 1. A structure for removing the existing anchor cables that intrude into the foundation pit of the station

[0046] A structure for cutting existing anchor cables intruding into the range of station foundation pits, including a cutting system and a clamp 5, the clamp 5 clamps the anchor cables, the cutting system cuts the anchor cables through a diamond wire saw 6, and the mechanism also includes There are hydraulic lifter 4 and moving steel frame 1, and hydraulic lifter 4 is installed on clamping tool 5; moving steel frame 1 includes horizontal moving steel frame 2 and vertical moving steel frame 3, hydraulic lifter 4 and clamping tool 5 Installed together on the traversing steel frame 2 and connected to the traversing module 25 inside the t...

Abstract

The invention discloses a structure and a processing method for cutting off an existing anchor cable invading the range of a station foundation pit. Plane movement and lifting movement of a clamping tool are achieved through a hydraulic lifter and a movable steel frame, so that the clamping tool can accurately find the position of an anchor cable through mechanical movement, the clamping effect on the anchor cable is achieved, and a crane or manual alignment and clamping are not needed; in addition, anchor cables in the same groove section can be accurately found and clamped one by one through movement, continuous cutting of the anchor cables in the same groove section is achieved, the cutting construction procedure is greatly accelerated, the cutting efficiency is improved, frequent disassembly and assembly are not needed, multiple clamping tools do not need to be installed, the structure is quite ingenious, and the equipment cost is saved; a diamond wire saw cut the anchor cable, that is, the diamond wire saw is driven by a hydraulic motor to move around the cutting face of the anchor cable at a high speed to grind the anchor cable, and cutting work is completed; due to the fact that diamond particles are used as grinding materials, hard objects such as the anchor cables can be cut.

Description

technical field [0001] The invention belongs to the field of construction treatment of existing anchor cables on the ground, and in particular relates to a structure and a processing method for removing existing anchor cables intruding into the range of station foundation pits. Background technique [0002] In the construction of foundation pits of urban subway stations, most of them are adjacent to existing buildings, and it is easy for anchor cables, anchor rods and other components left over from the underground part of the building to invade the scope of the foundation pits of subway stations. The new building adopts the existing groove grabbing machine and punching machine during the construction of underground diaphragm wall and pile foundation, and it is difficult for construction equipment to break or smash such steel components. In order to ensure the smooth construction of the foundation pit enclosure structure, the intruded anchor cables, anchor rods and other com...
