Underground structure supporting cross beam supporting structure and construction method
The invention relates to an underground structure supporting cross beam supporting structure and a construction method. The structure comprises a foundation pit formed by an underground continuous wall in an enclosure mode, a plurality of pine piles are buried at the bottom of the foundation pit, an inter-pile backfill layer and a concrete layer are sequentially laid above the pine piles from bottom to top, a scaffold is arranged above the concrete layer, and a bottom mould and a side mould for pouring a supporting cross beam are erected above the scaffold. Through the arrangement, the plurality of pine piles are inserted into the bottom of the foundation pit formed by the underground continuous wall in the enclosure mode, and the inter-pile backfill layer and the concrete layer are sequentially laid above the pine piles, so that the bottom of the foundation pit has a certain bearing capacity, longitudinal displacement is not likely to occur when the supporting cross beam is poured, the poured supporting cross beam has better mechanical properties, and the structure can be used for temporarily supporting the underground continuous wall and meanwhile serve as a permanent undergroundstructure, and has the effects of reducing construction procedures, shortening the construction period and saving reinforced concrete materials.
本发明涉及一种地下结构支撑横梁支护结构及施工方法，包括地下连续墙围护形成的基坑，基坑的底部埋设有若干松木桩，松木桩上方自下而上依次铺设有桩间回填层、混凝土层，混凝土层上方设置有脚手架，脚手架上方搭设用于浇筑支撑横梁的底模和侧模。通过上述设置，在地下连续墙围护而成的基坑的底部插入若干松木桩，并在松木桩上方依次铺设有桩间回填层和混凝土层，从而使基坑底部具有一定的承载能力，在浇筑支撑横梁的时候不容易发生纵向位移，从而使浇筑出的支撑横梁具有较佳的力学性能，能够在对地下连续墙做临时支护的同时还能兼做永久地下结构，具有减少施工工序，缩短施工周期，节约钢筋混凝土材料的效果。
