Land prefabricated immersed tube underneath pass tunnel construction method
The invention discloses a land prefabricated immersed tube underneath pass tunnel construction method, which comprises the following steps of: performing underneath pass tunnel construction by adopting a method of uniformly prefabricating and processing a tube body lining in a factory and then excavating earth to integrally sink, and installing a plumb gauge in the construction process to control the gradient and the descending uniformity of the immersed tube body lining. The stability and the construction effect in the sinking construction process are well guaranteed, meanwhile, construction of a large number of stirring piles, pile foundations, concrete supports and steel supports in the early stage of undercrossing the tunnel is avoided, the construction risk, the project cost and the environmental pollution are effectively reduced, and the period is shortened.
本发明公开了一种陆地预制沉管下穿隧道施工方法，采用管身衬砌先厂内统一预制加工、后挖土整体下沉的方法进行下穿隧道施工，施工过程中安装铅垂仪对下沉管身衬砌的倾斜度和下降均匀性进行控制，较好保证了下沉施工过程中的稳定性和施工效果，同时避免了下穿隧道前期大量的搅拌桩、桩基础施工、砼支撑和钢支撑的施工，有效降低了施工风险、工程造价、环境污染，缩短周期。
