Tidal influence near-river deep foundation pit steel-concrete combined inner support and construction method
The invention relates to a tidal influence near-river deep foundation pit steel-concrete combined inner support and a construction method, and adopts a structural form of combining a prestressed profile steel combined support with a reinforced concrete fringe truss, and the profile steel combined support is combined with an axial force servo system to accurately apply prestress. The top beam is poured at the top end of the fender post, the profile steel support is connected with the top beam at the end of the fender post through the embedded part, the prestressed profile steel combined support is convenient to mount and demount, use of large machines can be reduced to the maximum extent, and therefore occupation of a site is reduced to the maximum extent, and site arrangement is optimized. Compared with a traditional construction technology, the method has the advantages that the construction period is shortened, the construction efficiency is high, the comprehensive cost saving proportion is high, the expected design effect is achieved, remarkable economic, environment-friendly and social benefits are achieved, and the method has good application and popularization prospects.
本发明涉及一种潮汐影响临江深基坑钢‑混组合内支撑及施工方法，采用预应力型钢组合支撑结合钢筋混凝土边桁架的结构形式，将型钢组合支撑与轴力伺服系统相结合对预应力进行精确施加。围护桩顶端位置浇筑冠梁，型钢支撑通过预埋件与围护桩端部冠梁连接，且预应力型钢组合支撑安装、拆除方便，可最大幅度减少对大型机械的使用，从而最大程度的减少对场地的占用，优化场地布置。与传统施工技术相比，缩短工期、施工效率高、综合节约造价比例较高等优点，达到了设计预期的效果，取得了显著的经济、环保和社会效益，具有较好的推广应用前景。
