As shown in fig. 1 to 3, the present invention provides a directional pier stud dismantling device, which is used for dismantling a pier stud, and comprises:
the steel wire rope 4 is wound on the pier stud 2 to be dismantled; two ends of the steel wire rope 4 are respectively connected with a traction device 6, and any traction device 6 is connected with a ground anchor 7;
when the pier stud 2 is cut, pulling force is provided at the two ends of the steel wire rope 4 through the pulling device 6, so that the pier stud 2 can be directionally inclined.
In the technical scheme, firstly, the toppling direction and the plane angle of the pier stud are determined according to the actual situation of a construction site, and then the position of the ground anchor 7 is selected to manufacture the ground anchor 7. And calculating the dead weight of the pier stud 2 and the resultant force required by dumping, and calculating the tension value required to be distributed to the two ends of the steel wire rope 4 through the plane position. The perpendicular line is taken as the cut surface 3 according to the direction of the resultant force. And winding the steel wire rope 4 on the pier stud 2, connecting the two ends 4 of the steel wire rope with the traction devices 6, and connecting the traction devices 6 on the ground anchor 7. And providing a pulling force for the steel wire rope 4 through the pulling device 6, and then cutting along the determined cutting surface 3 by adopting cutting equipment to realize directional dumping of the pier stud 2. Finally, the steel wire rope 4, the traction device 6 and the ground anchor 7 are removed, and the collapsed pier stud 2 is subjected to demolition transportation. By adopting the technical scheme, the collapse direction can be specified in the construction process so as to reduce the influence on peripheral structures and the peripheral environment; and the risk that the concrete blocks are scattered irregularly and collapse dangerously due to the blasting mode or the mode of directly mechanically breaking the bridge pier column in the complex environment is solved.
In another embodiment, the top of the pier stud 2 is provided with a capping beam 1, and the steel wire rope 4 is wound at the connection position of the pier stud 2 and the capping beam 1. As shown in fig. 2, before cutting the piers 2, it is also necessary to uniformly cut the capping beams 1 according to the number of the piers 2.
In another embodiment, the ground anchors 7 connected to both ends of the steel wire rope 4 are disposed at both sides of the pier stud 2 in the falling direction. On the premise of the technical scheme, firstly, the toppling direction of the pier stud 2 is determined, then the positions of the ground anchors 7 are determined according to the field conditions on two sides of the toppling direction, the positions of the ground anchors 7 on the two sides can be asymmetrically arranged, and the pulling forces provided by the steel wire ropes 4 on the two sides of the pier stud 2 can be different.
