Reusable operation immersed tube tunnel foundation settlement disposal device and construction method
The invention relates to the technical field of immersed tunnels, in particular to a reusable operation immersed tunnel foundation settlement disposal device and a construction method.The reusable operation immersed tunnel foundation settlement disposal device comprises orifice pipes, slurry conveying pipes, check valves and grouting pipes, grouting holes are formed in a row in the longitudinal direction of a pipe joint at intervals of 10 m, the orifice pipes are arranged on a bottom plate after part of pressure bin concrete is chiseled away, and the grouting holes are formed in the bottom plate after part of pressure bin concrete is chiseled away; the orifice pipe is arranged above the pipe joint bottom steel plate by 200 mm, the orifice pipe is provided with a stirrup with the diameter of 8 mm, and hemp threads are wound on the pipe section below the stirrup. According to the method, a large grouting platform does not need to be erected beside a tunnel water area, and the influence on the surrounding environment and the channel is reduced; the grouting holes can be repeatedly used, so that the differential settlement disease prevention and control of the immersed tunnel foundation are facilitated; totally-closed construction is not needed, and the traffic influence is small; the precision of grouting construction is high, and improvement of the disease treatment efficiency is facilitated; the construction technology is simple, operation is convenient, labor cost is low, manufacturing cost is low, and the service life of the tunnel can be effectively prolonged.
本发明涉及沉管隧道技术领域，具体为可重复使用的运营沉管隧道基础沉降处置装置及施工方法，包括孔口管、输浆管、止回阀及注浆管四部分，其中，注浆孔沿管节纵向每间隔10m布置一排，所述孔口管在凿除部分压仓混凝土后在底板打设，所述孔口管打设至管节底钢板以上200mm，所述孔口管设有直径8mm箍筋，所述箍筋以下管段缠绕有麻丝。本发明,无需在隧道水域旁搭设大型注浆平台，减少了对周边环境及航道的影响；注浆孔可重复利用，有利于沉管隧道基础不均匀沉降病害防治；不需要全封闭施工，交通影响小；注浆施工的精度高，有利于提升病害整治效率；施工工艺简单，操作便捷，人工成本低，造价少，可有效延长隧道使用寿命。
