Foundation pit excavation method
The invention discloses a foundation pit excavation method which comprises the steps that a foundation pit is divided into a plurality of areas to be excavated, a first blocking structure and a second blocking structure are inserted into the foundation pit, and the first blocking structure, the second blocking structure and an enclosure structure jointly define the areas to be excavated; the peripheral side of the excavation area can be completely enclosed, so that excavation disturbance cannot be conducted to the outside of the excavation area or is conducted to be very small until earthwork between the excavation face and the target excavation face is completely excavated. By repeating the step of enclosing the to-be-excavated area, the first blocking structure, the second blocking structure and the enclosure structure jointly enclose a new to-be-excavated area, and then the to-be-excavated area is excavated until earthwork in the foundation pit is completely excavated, so that small deformation of small-area excavation can be realized to solve large deformation of large-range excavation.
本发明公开了一种基坑开挖方法，通过将基坑分为多个待开挖区域，在基坑内插入第一封堵结构、第二封堵结构，使第一封堵结构、第二封堵结构、围护结构共同围合一待开挖区域；可以将该开挖区域的周侧完全围合，使得开挖扰动不会传导到该开挖区域外或传导得很小，直至开挖面到目标开挖面之间的土方全部开挖完成。通过重复围合待开挖区域的步骤，使第一封堵结构、第二封堵结构、围护结构共同围合新的待开挖区域，再对待开挖区域进行挖掘，直至基坑内的土方全部开挖完成，可以实现小区域开挖的小变形来化解大范围开挖的大变形。
