Underwater bridge pier fine positioning device controlled by small-radius curve shape
The invention discloses a small radius curve linear control underwater pier fine positioning device which comprises a first side rod, a second side rod and at least one cross rod, the first side rod, the at least one cross rod and the second side rod are sequentially hinged, and guide holes are formed in the ends, away from the cross rod, of the first side rod and the second side rod. Outer marking rods are slidably connected into the guide holes, hinge sleeves are rotatably connected to the hinge positions of the first side rod, the at least one cross rod and the second side rod, auxiliary rods are slidably connected into the hinge sleeves, and two marking lines are arranged at the upper ends of the outer marking rods and the upper ends of the auxiliary rods at intervals. According to the method, the arcs are divided into a plurality of arcs, the steel pipes are driven into the arcs with the outer marking rods and the auxiliary rods as datum points, underwater bearing platform pouring is conducted through the steel hanging box technology, positioning and reference are facilitated, and the underwater positioning precision of the small-radius curve linear bridge is improved.
本发明公开了一种小半径曲线线形控制的水下桥墩精细定位装置，包括第一边杆、第二边杆和至少一个横杆，所述第一边杆、至少一个横杆与第二边杆依次铰接连接，所述第一边杆与第二边杆远离横杆的一端均设置导向孔，导向孔内滑动连接外标记杆，所述第一边杆、至少一个横杆与第二边杆的铰接处均转动连接铰接套，所述铰接套内滑动连接副杆，外标记杆和副杆上端均间隔设置两个标记线。本发明通过将圆弧分成若干，以外标记杆、副杆为基准点打入钢管并通过钢吊箱技术进行水中承台浇筑，便于定位和参照，使得小半径曲线线形桥，水下定位的精度提高。
