Foundation pit supporting structure and construction method thereof
The invention relates to a foundation pit supporting structure and a construction method thereof. The method at least comprises the steps that a soil layer is excavated to the first position of the top beam bottom elevation for the first time, and top beam blocking and wall construction is conducted; when the soil layer is excavated for the second time to a second position which is a first distance away from the position where the first steel supporting structure is located, the first steel supporting structure is arranged; and so on, earth excavation is continuously carried out until the foundation pit reaches the preset depth; the bottom structure of the soil layer lower than the position where the steel supporting structure is located comprises at least one pull groove with a certain inclination angle. According to the method, the construction progress can be improved according to the time and space relation, the water leakage phenomenon in the foundation pit is effectively controlled, and during earth excavation, the phenomena of steel support falling and slope instability can be effectively prevented.
本发明涉及一种基坑支护结构及其施工方法，所述方法至少包括：将土层第一次开挖至冠梁底标高的第一位置处并进行冠梁挡、墙施工；将土层第二次开挖至与第一钢支撑结构所在位置相距第一距离的第二位置处时设置第一钢支撑结构；以此类推，持续进行土方开挖，直至基坑达到预设深度；其中，低于钢支撑结构所在位置的土层的底部结构包括具有一定倾斜角度的至少一个拉槽。本发明能够从时间和空间关系改进施工的进度，有效控制基坑内的渗漏水现象，并且在土方开挖时，能够有效防止钢支撑脱落，边坡失稳的现象发生。
