Slide-down pre-support holding movable type deep foundation pit variable-spacing support construction method
The invention provides a slide-down pre-support holding movable type deep foundation pit variable-spacing support construction method. The method comprises the steps that A, a foundation pit enclosure structure is installed; b1, downhill pre-support construction is carried out; b2, construction of a permanent supporting layer; b3, constructing a temporary servo supporting layer; b4, construction of a permanent servo supporting layer; b5, carrying out displacement installation on the temporary servo supporting layer; the step B4 and the step B5 are repeated till the distance between the permanent servo supporting layer constructed at the last time and the bottom elevation of the foundation pit is smaller than the set depth; b6, foundation pit earthwork continues to be excavated in the space defined by the foundation pit support structure till the bottom elevation of the foundation pit is reached, and a foundation pit bottom plate is constructed; and the distance between the adjacent permanent servo supports is sequentially reduced from top to bottom. The method has the advantages of being capable of avoiding long-time interference of support construction and being used for completing support variable-distance installation, and the problem that supports are wasted due to equal-distance installation of the supports is solved.
本发明提供了一种滑降预支撑托持移动式深基坑变间距支撑施工方法，包括A、基坑围护结构安装；B1、滑降预支撑施工；B2、永久支撑层施工；B3、临时伺服支撑层施工；B4、永久伺服支撑层施工；B5、临时伺服支撑层移位安装；重复B4和B5步到最后一次施工出的永久伺服支撑层距离基坑底部标高的距离小于所述设定深度；B6、在基坑围护结构所围成空间内继续挖掉基坑土方至基坑底部标高，施工基坑底板；相邻的永久伺服支撑之间的距离从上向下依次变小。本发明具有能够避免支撑施工时长干扰和用于完成支撑变间距安装的优点，用于解决支撑等距安装浪费支撑的问题。
