Construction method of large-height-difference deep foundation pit close to existing building
The invention discloses a construction method of a large-height-difference deep foundation pit close to an existing building, which comprises the following steps: surveying and setting out, constructing the upper part of a foundation top elevation, constructing a support pile, constructing an inner support, excavating the foundation pit, removing the inner support, backfilling the foundation pit, constructing an inclined strut, constructing a retaining wall and removing the inclined strut. According to the construction method for the large-height-difference deep foundation pit close to the existing building, under the condition that the difference between the top elevation of the foundation pit and the bottom elevation of the enclosing wall of the existing building is large, and under the condition that a traffic lane with a certain width needs to be arranged between the edge of the foundation pit and the existing building, the stability of a foundation pit enclosure structure is improved; therefore, the stability of the existing building structure and the safety in foundation pit excavation construction are improved.
本发明公开了一种临近既有建筑物的大高差深基坑施工方法，包括测量放样、基顶标高上部施工、支护桩施工、内支撑施工、基坑开挖、内支撑拆除、基坑回填、斜撑施工、挡墙施工以及斜撑拆除的步骤，本发明的临近既有建筑物的大高差深基坑施工方法能够在基坑坑顶高程与既有建筑物的围墙底高程相差较大的情况下、基坑边缘与既有建筑物之间需要设置一定宽度的行车道的情况下，提高基坑围护结构的稳定性，从而提高既有建筑物结构的稳定性和基坑开挖施工中的安全性。
