Pipeline steel sheet pile flexible connection support installation construction method
The invention discloses a pipeline steel sheet pile flexible connection support installation construction method, and relates to a large-diameter PCCP (prestressed concrete cylinder pipe), which comprises the following steps: steel sheet pile construction: firstly excavating a trapezoidal cross section foundation pit in a construction site, and then sequentially inserting steel sheet piles into the ground through a pile machine from two ends of the bottom of the trapezoidal cross section foundation pit in a vertical posture and mutual occlusion connection mode; mounting of an inner supporting mechanism: clamping and transversely placing the steel enclosing purlins and tightly attaching the steel enclosing purlins to the inner sides of the steel sheet piles, and placing supporting steel pipes between the steel enclosing purlins distributed on the two sides; pipeline hoisting and butt joint are conducted, specifically, the pipeline is hoisted into the groove and is in butt joint with the pipeline on the front side; sealing and backfilling are conducted, specifically, the butted pipeline openings are sealed, and then subsequent groove backfilling is conducted; the flexible connection supporting system is optimized and innovated on the basis of a traditional steel sheet pile enclosing purlin supporting system, has high flexibility and flex resistance, can adapt to various geological conditions and changing soil pressure, can effectively guarantee safety and stability of a foundation pit, and reduces the influence of foundation pit excavation on building structure safety to the minimum.
本发明公开了管道钢板桩软联结支护安装施工工法，涉及大口径PCCP管道，包括：钢板桩施工：先于施工地开挖梯形截面基坑，再将钢板桩依次以竖直姿态且相互咬合连接的方式于梯形截面基坑底部两端通过桩机插入至地面中；内撑机构安装：将钢围檩夹紧横放并紧贴钢板桩内侧放置，并于分布两侧的钢围檩之间放置支撑钢管；管道吊装对接：将管道吊装至沟槽内，并与前侧管道对接；密封及回填：将对接的管道口进行密封，再进行后续的沟槽回填；本发明软联结支护体系是在传统钢板桩围檩支撑体系基础上的优化和创新，其具有高度的柔性和抗挠性能，能够适应各种地质条件和变化的土压力，能有效保证基坑的安全和稳定，将基坑开挖对建筑物结构安全的影响减小到最低。
