Deep foundation pit construction method based on bailey truss steel trestle
The invention discloses a deep foundation pit construction method based on a bailey truss steel trestle. The deep foundation pit construction method comprises the following steps that S1, a deep foundation pit support is installed; s2, a construction site is cleaned, then measurement positioning is conducted, and prefabricated reinforcement cages are evenly driven into the outer sides of excavation lines of the first foundation pit and the second foundation pit at intervals to the designed depth on the basis of measurement positioning; s3, before pile concrete is poured, the M20 bolts are inserted into the reinforcement cage; s4, steel pipe pile top distribution beams are installed, and the bottoms of the steel pipe piles are fixed through screws; s5, the bailey truss is spliced; s6, steel plates are transversely laid on the bailey trusses, and the bailey trusses and the steel plates are connected through full-length welding; and S7, protective fences are installed, and the protective fences are welded to the two sides of the In the invention, the bailey truss is erected between the steel pipe piles in the deep foundation pit to support the cross beam, and the bridge deck steel plate is welded on the cross beam, so that the integral steel trestle design is realized, the bridge deck area is large, engineering trucks and constructors can walk on the bridge deck conveniently, and the use is convenient.
本发明公开了一种基于贝雷架钢栈桥的深基坑施工方法，包括如下步骤：S1、深基坑支护安装；S2、清理施工现场，然后进行测量定位，以测量定位为基础，分别在第一基坑和第二基坑的开挖线外侧均匀间隔打入预制钢筋笼至设计深度；S3、桩混凝土浇筑前先把M20螺栓插入钢筋笼中；S4、安装钢管桩顶分配梁，并用螺丝固定钢管桩底部；S5、拼接好贝雷架；S6、贝雷架上横向铺设钢板，且贝雷架与钢板之间用满焊连接；S7、安装防护栏，钢板两侧焊接防护栏。本发明中，通过贝雷架在深基坑内的钢管桩间进行架设，从而支撑横梁，在横梁上焊接桥面钢板，从而实现整体式钢栈桥设计，桥面面积大，便于桥面上行走工程车以及施工人员，使用便捷。
