Method for reinforcing heavy-load hoisting foundation adjacent to unclosed deep foundation pit
The invention relates to the technical field of shield tunneling machine hoisting foundation reinforcement, and discloses a method for reinforcing a heavy-load hoisting foundation adjacent to an unclosed deep foundation pit, which comprises the following steps of: 1, determining the position of a truck crane according to the surrounding engineering environment of a shield pre-receiving end and the hoisting plane arrangement requirement, determining the specification and model of the truck crane according to the maximum component mass of the shield tunneling machine; secondly, the positions of the cast-in-place piles are determined and constructed; 3, after the construction of the bottom layer structure of the station is completed, a series of shield tunneling machine receiving work is carried out; fourthly, the shield tunneling machine receives the welded lifting lugs, the truck crane enters the site to be in place, and hoisting operation is carried out according to the shield tunneling machine disassembling scheme; and fifthly, the shield tunneling machine is hoisted, and the station main body structure is constructed. By the adoption of the method for reinforcing the heavy-load hoisting foundation adjacent to the unclosed deep foundation pit, the shield tunneling machine hoisting problem of a subway station without a closed structure can be solved, and a good effect is achieved for timely transition of the shield tunneling machine and shortening of the construction period.
本发明涉及盾构机吊装地基加固技术领域，且公开了一种紧邻未封闭深基坑的重载吊装地基加固方法，包括以下步骤：步骤一，根据盾构预接收端头的周边工程环境、吊装平面布置要求，确定汽车吊位置，根据盾构机最大部件质量确定汽车吊规格型号；步骤二，灌注桩位置确定并施工；步骤三，车站底层结构施作完成后，进行盾构机接收系列工作；步骤四，盾构机接收完成焊接吊耳，汽车吊进场就位，根据盾构机拆机方案，实施吊装作业；步骤五，盾构机吊装完成，进行车站主体结构施工。本发明采用上述一种紧邻未封闭深基坑的重载吊装地基加固方法，能够解决未形成封闭结构的地铁车站的盾构机吊装难题，为盾构机及时转场，缩短施工工期起到了良好作用。
