Basement deep foundation pit replacement support and construction method thereof
The invention relates to a basement deep foundation pit replacement support which is characterized in that a concrete force transmission belt is arranged between a basement outer wall and a foundation pit row pile, the concrete force transmission belt comprises a vertical force transmission belt corresponding to a basement outer wall frame column and a horizontal force transmission belt corresponding to a ground floor and a floor slab, and a grid formed by the horizontal force transmission belt and the vertical force transmission belt is filled with graded gravel; a steel pipe inclined support is arranged at a broken plate in the foundation pit; dowel bars are arranged in all post-cast strip construction joints in the foundation pit and fractures of floor slabs; the invention further provides a construction method of the basement deep foundation pit replacement support. The construction method comprises the steps that the steel pipe inclined support is installed at the position of a broken plate in a foundation pit to reinforce and transfer force; comprising the following steps: mounting dowel bars at a post-cast strip construction joint and a hole opening constructed in a foundation pit; comprising the steps that a concrete force transmission belt and graded gravel are filled in a manure groove between a basement outer wall and a foundation pit row pile; the structures in the foundation pit are combined into an integral force transmission system, and after the inner support is removed, the force transmission system effectively supports the foundation pit structure.
本发明涉及一种地下室深基坑替换撑，在地下室外墙与基坑排桩之间设有混凝土传力带，混凝土传力带包括与地下室外墙框架柱对应的竖向传力带，与底楼、楼板对应的水平传力带，水平传力带、竖向传力带组成的格子中填充级配砂石；基坑内部断板处设置钢管斜支撑；基坑内所有后浇带施工缝中以及楼板的断口中设有传力杆；本发明还提供了上述地下室深基坑替换撑的施工方法，包括在基坑内断板位置安装钢管斜支撑加固传力的步骤；包括在基坑内构造的后浇带施工缝及洞口位置安装传力杆的步骤；包括在地下室外墙与基坑排桩之间的肥槽中填充混凝土传力带和级配砂石的步骤；将基坑内的构造联合成整体传力体系，在拆除内支撑后，上述传力体系有效支撑基坑结构。
