Pi-shaped cable-stayed bridge small-space support dismantling method
The invention discloses a Pi-shaped cable-stayed bridge small-space support dismantling method, and provides the following scheme aiming at the problems that the dismantling process is low in safety, slow in progress and only suitable for dismantling of bridge supports in a general environment. Referred equipment comprises a bridge body, a crane and a winch, the crane and the winch are arranged on the ground, supporting columns are arranged on the outer wall of the bottom of the bridge body, a disc buckle support is arranged between every two adjacent supporting columns, and an extraction device is arranged on the crane. The pi-shaped cable-stayed bridge beam small-space support dismantling method comprises the following steps: S1, unloading a sand cylinder, and opening a sand leakage valve of the sand cylinder, so that sand slowly flows out, and the gap with a longitudinal beam is reduced until enough gap exists. In the dismantling process, dismantling is carried out in order in the mode that the supports are sequentially and circularly unloaded from a midspan to support bases, at the non-bearing positions dismantling is firstly dismantled, and then at the bearing positions dismantling is performed, the safety of dismantling workers is greatly guaranteed, and meanwhile the dismantling efficiency is high.
本发明公开了π字形斜拉桥梁小空间支架拆除方法，针对针对拆除过程安全性较低、进程缓慢以及只适用于一般环境下的桥梁支架拆除的问题，现提出以下方案，包括桥体、吊车和卷扬机，所述吊车和卷扬机设置在地面上，所述桥体的底部外壁上设有支柱，且两个相邻支柱之间均设有盘扣支架，所述吊车上设有抽取装置，所述π字形斜拉桥梁小空间支架拆除方法包括如下步骤：S1：卸落砂筒，打开砂筒的漏沙阀门，沙体缓缓流出，与纵梁间隙降低直至有了足够的间隙。本发明在拆除过程中，遵循由跨中至支座处依次循环卸落支架，先拆非承重的、后拆承重位置的方式有序进行拆除，极大保证了拆除工作的人员安全的同时拆除效率较高。
