Hydraulic shearing dismantling method for light steel pipe frame system structure

The invention discloses a hydraulic shear dismantling method for a light steel pipe frame system structure, which comprises the following steps: S1, carrying out computational simulation analysis, and finding out a force transmission path; s2, dividing a main body structure into eight construction units according to deformation joints of an original venue structure; s3, on-site preparation work in the early stage of shearing is conducted; and S4, two long-arm excavator double-cylinder hydraulic shears are used, and the two symmetrical unit pipe frames are sheared and dismantled at the same time. According to the hydraulic shearing dismantling method for the light steel pipe frame system structure, the double-cylinder hydraulic shear of the long-arm excavator is adopted for dismantling the light steel pipe frame system structure, manpower can be saved, the construction period is shortened, potential safety hazards are reduced, noise and dust are little, and the influence on the surrounding environment is small
