Foundation pit supporting method close to existing building
The invention discloses a method for supporting a foundation pit close to an existing building. The method comprises the following steps that the positions of a first supporting pile group and a second supporting pile group are lofted; a first support pile and a second support pile are constructed at the position of the first support pile group, and a third support pile is arranged at the position of the second support pile group; a first top beam is constructed on the pile top of the first supporting pile, and a second top beam is constructed on the pile top of the third supporting pile; after construction of the basement structure is completed, a backfill layer between the second support pile group and the basement structure is backfilled; inclined struts are arranged between the first support pile group and the second support pile group; a soil body between the first supporting pile group and the second supporting pile group is excavated, and after the soil body is excavated to the top elevation of the second top beam, a retaining wall is constructed, and the inclined struts are dismantled; according to the method, the existing building can be effectively protected under the conditions that the existing building is close to the foundation pit, and the difference between the elevation of the existing building and the top elevation of the foundation pit is large, and the structural safety of the existing building is guaranteed.
本发明公开了一种临近既有建筑物的基坑支护方法，该方法包括以下步骤：放样出第一支护桩组和第二支护桩组的位置；在第一支护桩组的位置处分别施工第一支护桩和第二支护桩，在第二支护桩组的位置处设置第三支护桩；在第一支护桩的桩顶施工第一冠梁，在第三支护桩的桩顶施工第二冠梁；待地下室结构施工完成后，回填第二支护桩组与地下室结构之间的回填层；在第一支护桩组和第二支护桩组之间设置斜撑；开挖第一支护桩组和第二支护桩组之间的土体，土体开挖至第二冠梁的顶高程后，施工挡墙以及拆除斜撑；本发明的方法能够在紧邻既有建筑物并且既有建筑物的高程与基坑顶高程相差较大的情况下对既有建筑物有效防护，保证既有建筑物的结构安全。
