Method for dismantling pier stud bent cap with upper structure reserved on viaduct
The invention relates to a method for dismantling a pier stud bent cap with an upper structure reserved on a viaduct. The method comprises the steps that A, a bridge deck is jacked; b, mounting an anti-overturning bag lifting device; c, a bent cap limiting protection device is installed; d, the pier column is separated from the bent cap; e, pier column cutting and dismantling are conducted, specifically, the pier column is divided into two half parts distributed in the transverse bridge direction to be dismantled alternately from top to bottom, and pier column cutting and dismantling specifically comprises the following steps that E1, a semi-cylinder on the inner side of the pier column is cut and dismantled for the first time; e2, cutting and removing a semi-cylinder on the outer side of the pier column for the first time; e3, the semi-cylinder on the inner side of the pier column is cut and dismantled again; e4, the semi-cylinder on the outer side of the pier column is cut and dismantled again, and the step E3 and the step E4 are repeated till the pier column is cut to the set residual length; f, the bent cap is cut in a blocking mode; the device can be used for dismantling the bent cap which is limited in space and not suitable for the blasting working condition, and the dismantling problem of the bent cap which is limited in space and not suitable for the blasting working condition is solved.
本发明涉及一种高架桥保留上部结构式墩柱盖梁拆除方法，包括A、顶升住桥面板；B、防倾覆兜吊装置安装；C、盖梁限位保护装置安装；D、墩柱与盖梁分离；E、墩柱切割拆除：将墩柱分为沿横桥向分布的两个半部进行自上而下交替拆除，墩柱切割拆除具体包括以下步骤：E1、首次切割拆除墩柱内侧半圆柱；E2、首次切割拆除墩柱外侧半圆柱；E3、再次切割拆除墩柱内侧半圆柱；E4、再次切割拆除墩柱外侧半圆柱，重复E3和E4直至将墩柱切割到残留设定长度；F、盖梁分块切割；本发明具有能够用于空间受限不适宜爆破工况的盖梁拆除的有的，解决了空间受限不适宜爆破工况的盖梁的拆除问题。
