Construction method of deep foundation pit support based on upper-soft lower-hard rock stratum
The invention provides a construction method of a deep foundation pit support based on an upper-soft lower-hard rock stratum, and relates to the technical field of building construction. The construction method comprises the following steps that S1, the strength of a to-be-constructed position is surveyed, and supporting construction is carried out when the strength of a lower rock stratum is not smaller than the strength of moderately-weathered limestone; and S2, composite foundation pit supporting is carried out at the to-be-constructed position, the composite foundation pit supporting comprises a foot lifting pile, a foot locking beam and a steel pipe column, or the composite foundation pit supporting comprises the foot lifting pile, the foot locking beam and a soil nailing wall. According to the construction method of the deep foundation pit support based on the upper-soft lower-hard rock stratum, the construction efficiency and the construction quality are greatly improved, the construction cost is obviously reduced, and the construction period is shortened.
本申请提供了一种基于上软下硬岩石地层的深基坑支护的施工方法，涉及建筑施工的技术领域。该施工方法，包括以下步骤：S1、勘测待施工位置的强度，并在下部岩石地层的强度满足不小于中风化石灰岩的强度的条件时进行支护施工；S2、在待施工位置进行复合基坑支护，复合基坑支护包括吊脚桩、锁脚梁和钢管柱，或者，复合基坑支护包括吊脚桩、锁脚梁和土钉墙。该施工方法，极大提高了施工效率和施工质量，明显降低了施工成本，缩短了工期。
