Partition wall support conversion method in foundation pit division construction of deep foundation pit
The invention discloses a partition wall support conversion method in foundation pit division construction of a deep foundation pit. The partition wall support conversion method comprises the steps that firstly, the deep foundation pit is divided into a plurality of construction areas; soil body excavation is carried out on one of the two structures, an inner support is arranged, then a bottom plate structure is constructed, support changing profile steel is arranged, the inner support is dismantled, and an underground structure is constructed layer by layer; then, an area adjacent to the deep foundation pit formed through excavation is excavated; the support changing profile steel is installed, an upper inner support is dismantled, a through hole is formed in the mid-partition wall, when the underground structure is constructed layer by layer, a structural beam of the later-excavated deep foundation pit penetrates through the mid-partition wall through the through hole to be connected with a corresponding structural beam in the previous deep foundation pit, a support changing structural beam is formed, and the support changing profile steel of the later-excavated deep foundation pit is eliminated; and middle partition walls and plates between the two deep foundation pits are dismantled layer by layer from top to bottom to form an integral structure. Compared with the prior art, the support changing profile steel in adjacent areas is eliminated; and the defects that materials are wasted, stress is unstable, and transmission of force on the two sides cannot be guaranteed in the demolition process of the midground wall are overcome.
本发明公开了一种深基坑分基坑施工中隔墙支撑转换方法，该方法首先将深基坑分隔成多个施工区域；对其中一个进行土体开挖并设置内支撑，再施工底板结构并设置换撑型钢，拆除内支撑并逐层施工地下结构；然后对开挖形成的深基坑相邻的区域进行开挖；安装换撑型钢，拆除上部内支撑，在中隔墙上开贯穿孔，当逐层施工地下结构时，后开挖深基坑的结构梁通过贯穿孔穿过中隔墙与前一深基坑中的对应结构梁连接，形成换撑结构梁，取消后开挖深基坑换撑型钢的设置；由上至下逐层拆除两个深基坑之间的中隔墙，板形成整体结构；与现有技术相比，取消了相邻区型钢换撑的设置；避免材料浪费、受力不稳定，地中壁拆除过程中无法保障两侧力的传递等弊端。
