Construction method of support direct descending movable type deep foundation pit variable-spacing support
The invention provides a construction method for a movable type deep foundation pit variable-spacing support with a support directly descending function. The construction method comprises the steps that A, a foundation pit enclosure mechanism is installed; b1, constructing a first permanent support; b2, temporary servo support construction; b3, permanent servo support construction is carried out; b4, temporary servo support displacement installation is carried out; the step B3 and the step B4 are repeated till the distance between the permanent servo support installed at the last time and the bottom elevation of the foundation pit is smaller than the set depth; b5, foundation pit earthwork continues to be excavated in the space defined by the foundation pit enclosure mechanism 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 device has the advantage that the supports can be mounted at variable intervals, and the problem that the supports are wasted due to equidistant mounting of the supports is solved.
本发明提供了一种支撑直接下降移动式深基坑变间距支撑施工方法，包括A、基坑围护机构安装；B1、首道永久支撑施工；B2、临时伺服支撑施工；B3、永久伺服支撑施工；B4、临时伺服支撑移位安装；重复B3和B4步到最后一次安装的永久伺服支撑距离基坑底部标高的距离小于所述设定深度；B5、在基坑围护机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。
