Embodiment Construction
[0033] Hereinafter, the present invention will be described in further detail in conjunction with the accompanying drawings.
[0034] Taking the underground diaphragm wall project construction of the main enclosure structure of Shenzhen City Rail Transit Line 7304-2 Biaofumin Station as an example, the present invention is cutting the underground anchor cable cutting construction method, comprising the following steps:
[0035] (1) Selection of equipment and tools
[0036] In order to ensure the construction efficiency, and according to the needs of easy installation and relocation of the guide wall construction, the E-1812A / DSM-10A hydraulically driven diamond wire saw machine driven by electricity is selected, and the diamond wire saw cutting process is adopted. Its characteristics are: Fast, efficient, cutting precision and good integrity cutting and demolition anchor cable.
[0037]According to the technical requirements of diamond wire saw cutting, the retaining mud in t...

The invention provides an underground anchor cable cutting construction method and a cutting device thereof. The cutting device comprises a diamond rope, a diamond rope guide fixing wheel arranged in an underground groove, a diamond rope sawing machine fixing base, a driving wheel for driving a diamond rope sawing machine, a remote controller for remotely controlling the diamond rope sawing machine to operate and a diamond rope sawing machine power pump station. The cutting device further comprises a cutting support bottom, a cutting support upper portion and a cutting support fixing portion. The cutting support bottom comprises an anchor cable clamping location guide part, an anchor cable clamping jaw, an anchor cable clamping hydraulic device and a pump station. The cutting support fixing portion comprises a diamond rope sawing machine base fixing part and connection parts which are used for enabling a support to be fixedly connected with the ground. The cutting device can cut underground anchor cables in slurry, can quickly and efficiently cut with good cutting accuracy and completeness, and is high in cutting-off rate and small in cutting size deviation ratio.
Description
technical field [0001] The invention relates to reinforced concrete cutting technology, in particular to a cutting construction method and a cutting device for underground anchor cables used for underground slope support. Background technique [0002] In the new construction of industrial and civil buildings, the slope support of the adjacent buildings constructed in the early stage is supported by driving anchor cables during underground construction, and the existing anchor cables are permanently left behind after completion. When needing to build new building near it, need to build the underground continuous wall of 1 meter wide, and existing anchor cable removal routine method is: 1, adopt percussion drilling rig, utilize percussion drill bit to impact anchor cable repeatedly Breaking, this method is very difficult to break due to the good elasticity of the anchor cable. At the same time, the broken anchor cable seriously affects the installation of the lowered reinforce...
