Tower group arrangement method of tower crane for group pit construction
The invention discloses a tower group arrangement method of group pit construction tower cranes, and particularly relates to a group pit construction tower crane group planning method which combines staggered subtraction of heights of adjacent tower cranes, triangular intersection of a main tower crane and an auxiliary tower crane and nine-grid multi-stage construction of a deep foundation pit. The method is suitable for construction of an underground structure and an overground structure of an ultra-large deep foundation pit, the construction time of a truck crane is shortened, the lifting frequency of the tower crane is reduced, the subpackage entering frequency of the tower crane is reduced, and then the construction cost is reduced. The problems that an ultra-large type deep foundation pit is hoisted and constructed through a truck crane for a long time, cost is high, a road needs to be occupied, and construction is affected are solved.
本发明公开了一种群坑施工塔吊的塔群布设方法，利用相邻塔吊高度上错位相减、主塔吊与辅助塔吊形成三角形交汇和深基坑采用九宫格多阶段施工相结合的群坑施工塔吊的群塔策划方法，适用于超大型深基坑的地下结构和地上结构的施工，降低汽车吊的施工时间，减少塔吊提升次数、减少塔吊分包进场次数，进而降低施工成本。本发明解决了超大型深基坑长期采用汽车吊吊装施工，成本高且需占用道路而影响施工的问题。
