Construction method for staggered floor running water of underground earthwork structure of reverse construction
The invention discloses a construction method for staggered floor running water of an underground earthwork structure of reverse construction, which comprises the following steps of: dividing a to-be-constructed area of a foundation pit into an area A and an area B, and further dividing the area A into an area A1 positioned in the foundation pit and an area A2 positioned on the periphery of the foundation pit; the area A1 and the area B are excavated to the position between the first underground layer and the second underground layer, and then structural beam plates of the first underground layer of the area A1 and the area B are constructed; and after beam plates of the first underground layer structures of the A1 area and the B area reach the design strength, the A2 area is excavated to the position between the first underground layer and the second underground layer, then a side span structure of the A2 area is constructed, and the side span structure of the A2 area is connected with the beam plates of the first underground layer structures of the A1 area. The technical problem that in the prior art, a foundation pit reverse construction method is a whole-layer operation mode, and cost is seriously increased is solved. By means of the alternate operation mode, large machines of labor force work in a crossed mode, the problem of work type stagnation does not exist, and underground line production and overground line production do not interfere with each other.
本发明公开了一种逆作工程地下土方结构错层流水的施工方法，包括如下步骤：将基坑待施工区域分为A区和B区，进一步将A区分位于基坑内部的A1区和位于基坑周边的A2区；对A1区和B区进行开挖，并挖至地下一层至地下二层之间，然后施工A1区和B区地下一层结构梁板；在A1区和B区地下一层结构梁板达到设计强度后，开挖A2区，并开挖至地下一层至地下二层之间，然后施工A2区边跨结构，并将该A2区边跨结构与该A1区地下一层结构梁板连接。本发明解决了现有技术中基坑逆作法为整层作业方式，使成本增加严重的技术问题。本发明的轮流作业方式使劳动力的大型机械交叉作业，不存在工种的停滞的问题，且使得地下流水作业的地上流水作业互不干扰。
