Construction method of cast-in-place bridge steel pipe pile underwater support dismantling system
The invention relates to a construction method of a cast-in-place bridge steel pipe pile underwater support dismantling system, and belongs to the technical field of bridge engineering, and the construction method comprises the following steps: S1, when a cast-in-place beam is constructed, preformed holes are formed in the positions, directly facing the two ends of each bearing beam, of the cast-in-place beam; s2, after concrete of the cast-in-place beam reaches the form stripping strength, two cross beams are erected at the reserved hole positions of the cast-in-place beam, and a supporting beam is erected above the cross beams; s3, a lifting rod is arranged in each preformed hole, the top end of each lifting rod penetrates through the supporting beam, the bottom end of each lifting rod penetrates through the bearing beam and is fixedly provided with a supporting block, and the supporting beam is provided with a driving assembly for driving the corresponding lifting rod to move up and down; s4, when the support is dismantled, the steel pipe pile and the bearing beam are firstly dismantled, and at the moment, the bearing beam is lifted by the suspender; and S5, then the driving assembly drives the suspender to move downwards, the supporting block moves along with the suspender, and the bearing beam descends along with the supporting block till the bearing beam descends to the ground. The method has the effect of improving the dismounting speed of the support.
本申请涉及一种现浇桥梁钢管桩水中支架拆除体系的施工方法，属于桥梁工程的技术领域，其包括如下步骤：S1、现浇梁在施工时，在现浇梁正对每根承重梁两端的位置处均设置预留孔；S2、当现浇梁的混凝土达到拆模强度后，在现浇梁的预留孔位置处搭设两个横梁，横梁的上方搭设有支撑梁；S3、每个预留孔中均设置有吊杆，吊杆的顶端贯穿支撑梁，吊杆的底端贯穿承重梁并固定有支撑块，支撑梁上设置有驱动吊杆上下移动的驱动组件；S4、对支架进行拆除时，先将钢管桩与承重梁拆开，此时承重梁由吊杆提吊；S5、然后驱动组件驱动吊杆向下移动，支撑块随着吊杆移动，承重梁随着支撑块下降，直至承重梁下降到地面上。本申请具有提高支架的拆除速度的效果。
