地铁车站盖挖法施工是一种常用的施工方法,而其中盖挖逆作法是一种关键技术多、施工相对复杂的施工方法,本文以具体的工程实例为背景,从钢管立柱的施工、土方开挖施工、结构板及下翻梁地膜施工、侧墙三角桁架施工、混凝土接缝渗漏处理等五个关键技术介绍了其在工程实体中的应用。 The subway station cover excavation method is a common construction method, and the cover excavation reverse method is a key technology, the construction is relatively complex construction methods. In this paper, the specific project as the background, from the steel pipe column construction, earthwork Excavation construction, structural board and under the turn of the plastic film construction, the construction of the side wall triangular truss, concrete joints leakage treatment of five key technologies introduced its application in engineering entities.
