Cover excavation construction method for building subway station by means of shield tunnel
The invention relates to a cover excavation construction method for building a subway station by means of a shield tunnel. The method comprises the following steps that downward excavation is carried out at the design position of the station to construct a station wall body, and a part of the wall body in the construction range of the shield tunnel is enabled to be a machinable temporary wall body; a shield tunneling machine is used for excavating along the tunnel design contour line, and the machinable temporary wall body is excavated while shield tunnel construction is conducted to construct a tunnel lining structure; and when the soil body between the station wall bodies is excavated to the tunnel lining position, the tunnel lining structure is dismantled, and station structure construction is conducted. According to the cover excavation construction method shield, the tunneling method and the cover excavation method are combined to solve the problems existing in the prior art, arrangement of tunnel construction vertical shafts is reduced, the station building scale is reduced, the station cover excavation construction period is shortened, and the tunnel and station construction efficiency is improved.
本发明涉及一种借助盾构隧道修建地铁站的盖挖工法，所述工法为：在车站设计位置向下开挖施作车站墙体，处于盾构隧道施工范围的部分墙体为可切削临时墙体；利用盾构机沿隧道设计轮廓线挖掘，进行盾构隧道施工的同时对可切削临时墙体进行掘削，并施作隧道衬砌结构；开挖车站墙体之间的土体至隧道衬砌位置处时拆除隧道衬砌结构，进行车站结构施作。本发明结合盾构法与盖挖法解决现有技术中存在的问题，减少了隧道施工竖井设置，降低了车站建筑规模，缩短了车站盖挖施工周期，提高了隧道及车站施工效率。
