Concrete arch bridge cast-in-place arch center dismantling method
The invention discloses a concrete arch bridge cast-in-place arch center dismantling method. The method comprises the steps that S1, a temporary arch support is designed; s2, before dismantling, the pushing side adjusts the positions of the buckle cable and the carrying pole beam to be away from the arch rib direction, and the width is determined according to the dismantling width; s3, the two temporary skewback pushing systems work, and synchronous pushing is carried out till the dismantling width is reached; s4, a tower crane hoists a steel wire rope to be installed on the segment to be dismantled, connecting bolts on the two sides of the segment are dismantled, the segments are hoisted to the ground through the tower crane and then dismantled one by one, and the segments are transported away from the operation site after being stored; s5, after the first truss is detached, the carrying pole is moved to the original position of S2 towards the pushing side; and S6, the steps S3-S5 are repeated, and the next truss is dismantled till overall dismantling is completed. The method has the technical effects and advantages that 1, the operation risk when the arch center is dismantled is reduced; 2, the arch frame to be dismantled is transversely pushed to a vertical hoisting range of a tower crane outside an arch rib, so that the utilization rate of mechanical equipment is improved, and the working efficiency is improved;
本发明公开了一种混凝土拱桥现浇拱架拆除方法，包括：S1、设计临时拱座；S2、拆除前,顶推侧调整扣索与扁担梁位置，至远离拱肋方向，宽度根据拆除宽度确定；S3、两临时拱座顶推系统工作，同步顶推至拆除宽度；S4、塔吊吊装钢丝绳安装在即将拆除的节段,拆解节段两侧连接螺栓，节段通过塔吊吊放至地面后逐片拆除、存放后运离作业场地；S5、第一榀拆除后，向顶推侧移动扁担至S2所在原位置；S6、重复S3‑S5，进行下一榀拆除，直至完成整体拆除。本发明的技术效果和优点：1、降低拱架拆除时的作业风险；2、将要拆除的拱架横推至拱肋外面塔吊可垂直吊运范围，提高机械设备使用率，提高工效。
