Mutual-pulling type foundation pit enclosure structure and construction method
The invention discloses a mutual-pulling type foundation pit enclosure structure and a construction method. The mutual-pulling type foundation pit enclosure structure comprises a double-shaft stirring pile located between a first foundation pit and a second foundation pit. The double-shaft stirring pile comprises a first stirring pile body and a second stirring pile body. The top of the first stirring pile body and the top of the second stirring pile body are connected with prestressed steel strands. Matched clamps are anchored to the prestressed steel strands. A first base plate force transmission belt is arranged between the first stirring pile body and a base plate of the first foundation pit. A second base plate force transmission belt is arranged between the second stirring pile body and a base plate of the second foundation pit. When the enclosure structure is constructed, the first stirring pile body and the second stirring pile body are arranged between the first foundation pit and the second foundation pit and fixed to the two foundation pits through the first base plate force transmission belt and the second base plate force transmission belt correspondingly, and tensioning type enclosure of the first foundation pit and the second foundation pit is achieved through the prestressed steel strands. The construction process is simple, the period is short, and the mutual-pulling type foundation pit enclosure structure is suitable for enclosure of the near foundation pits.
本发明公开了一种互拉式基坑围护结构及施工方法，互拉式基坑围护结构包括位于第一基坑和第二基坑之间的双轴搅拌桩，双轴搅拌桩包括第一搅拌桩和第二搅拌桩；第一搅拌桩的顶部和第二搅拌桩的顶部连接有预应力钢绞线，预应力钢绞线锚固有相匹配的夹具；第一搅拌桩与第一基坑的底板之间设有；第二搅拌桩与第二基坑的底板之间设有第二底板传力带。上述围护结构施工时，在第一基坑和第二基坑之间设置第一搅拌桩和第二搅拌桩，且第一搅拌桩和第二搅拌桩分别通过第一底板传力带和第二底板传力带与两个基坑相固定，并通过预应力钢绞线实现对第一基坑和第二基坑的拉紧式围护；该施工过程简单周期短，适用于较近基坑的围护。
