Offshore shield tunnel water taking facility and construction method thereof
The invention discloses an offshore shield tunnel water taking facility and a construction method thereof, the water taking facility comprises a water taking main body structure and a steel cylinder, the water taking main body structure comprises a water taking well and is arranged in the steel cylinder, and the steel cylinder is inserted into a seabed; the steel cylinder is provided with a water taking window and a tunnel connector, and a tunnel is connected into the water taking main body structure through the tunnel connector. The water intake window is communicated with the water intake well, and the water intake well is communicated with the tunnel; a water intake gate is arranged between the water intake well and the water intake window, and a tunnel gate is arranged between the water intake well and the tunnel. The steel cylinder is fixed firstly, then the water taking main body structure is constructed, the tunnel cylinder connector is formed, and finally the water taking window is formed. In this way, offshore dry construction conditions can be provided, cofferdams and steel cylinders do not need to be additionally constructed to serve as permanent structures, one object has two purposes, dismantling is not needed after construction is completed, the construction period can be shortened, and the influence of construction on the environment is reduced; and through the water intake gate and the tunnel gate, the dry overhaul of the tunnel and the dry overhaul of the water intake facility can be realized.
本发明公开了一种海上盾构隧洞取水设施及其施工方法，取水设施包括有取水主体结构和钢圆筒，取水主体结构包括有取水井并设置在钢圆筒内部，钢圆筒插入海床中；钢圆筒开设有取水窗口和隧洞接口，隧洞通过隧洞接口接入取水主体结构；取水窗口与取水井连通，取水井与隧洞连通；取水井与取水窗口之间设有取水闸门，取水井与隧洞之间设有隧洞闸门。先固定钢圆筒，再施工取水主体结构及开设隧筒接口，最后开设取水窗口。如此可提供海上干施工条件，不需要另外建设施工围堰，钢圆筒作为永久结构，一物两用，施工完成后不需要拆除，可缩短工期，减小施工对环境的影响；通过取水闸门和隧洞闸门可实现隧洞干检修和取水设施自身的干检修。
