Efficient construction method for underground ultra-wide underpass
The efficient construction method comprises the following steps that S1, excavation construction is conducted on a field level on the surface of the underpass channel position, and a row of outer side steel sheet piles and a row of inner side steel sheet piles are arranged in a driving mode; s2, after excavation is conducted to the designed bottom elevation of the channel, foundation treatment is conducted, and pedestrian and imminent road side boxes and semi-U-groove side walls are formed at the rear end and the front end of the underpass channel through pouring; s3, earth of the main lane is excavated to the designed bottom elevation of the channel; and S4, a movable formwork trolley is introduced into the main lane, a photo frame structure is poured and constructed, the photo frame structure and the pedestrian and imminent mixed road side box jointly form an underpass channel overall structure, an underpass channel bottom is poured at the bottom of the main lane, and the underpass channel bottom and the semi-U-groove side wall jointly form an underpass channel U-groove whole. According to the construction method disclosed by the invention, the permanent structure of the pedestrian and imminent mixed road side box and the temporary structure of the template moving trolley are combined, and an assembly technology is implanted into engineering construction, so that green and rapid construction of the ultra-wide underground passage is realized.
本发明公开了一种地下超宽下穿通道高效施工方法，包括以下步骤：S1、对下穿通道位置表面的场坪进行开挖施工，分别打设一排外侧钢板桩和一排内侧钢板桩；S2、开挖至通道设计底标高后进行地基处理，在下穿通道的后端和前端浇筑形成人非混行道边箱和半U槽侧墙；S3、对主车道的土方开挖至通道设计底标高；S4、向主车道引入移动模板台车，并进行浇筑施工相框架结构，其和人非混行道边箱共同形成下穿通道整体结构，在主车道的底部浇筑下穿通道底部，其和半U槽侧墙共同形成下穿通道U槽整体。本发明的施工方法将人非混行道边箱永久结构和模板移动台车临时结构相结合及装配化技术植入工程建造中，以实现超宽地下通道绿色化、快速化施工。
