Water taking and draining structure of nuclear power plant and construction method
The invention relates to the technical field of nuclear power plant sea area water taking and draining engineering, in particular to a nuclear power plant water taking and draining structure and a construction method.The nuclear power plant water taking and draining structure comprises a water retaining steel cylinder, a caisson buried in a seabed and a shield tunnel used for being communicated with a nuclear power plant water taking and draining device, and a shield tunneling machine receiving end wall is arranged on one side face of the caisson; the shield tunneling machine receiving end wall is used for enabling the shield tunneling machine to penetrate into the caisson, so that the shield tunnel is communicated into the caisson; a hoisting opening is formed in the top end of the caisson and used for hoisting out the shield tunneling machine penetrating into the caisson; a cover plate is arranged at the hoisting opening and used for sealing the hoisting opening after the shield tunneling machine is hoisted out. At least one mounting opening communicated with the interior of the caisson is formed in the top end of the cover plate and is used for mounting a water taking and draining head; the bottom end of the water retaining steel cylinder is detachably and fixedly connected with the top end of the caisson, the height of the top end of the water retaining steel cylinder extending to the position above the sea level is not smaller than the preset height, and the water retaining steel cylinder is used for preventing seawater from entering the caisson.
本发明涉及核电厂海域取排水工程技术领域，特别涉及一种核电厂取排水结构及施工方法，包括挡水钢筒、埋设在海床中的沉箱和用于与核电厂取排水装置连通的盾构隧道，沉箱的一个侧面上设置有盾构机接收端墙，盾构机接收端墙用于盾构机穿入沉箱内，使盾构隧道连通至沉箱内；沉箱的顶端开设有吊装口用于将穿入沉箱内的盾构机吊出；吊装口处设置有盖板，盖板用于在盾构机吊出后封闭吊装口；盖板的顶端设置有至少一个连通沉箱内部的安装口，安装口用于安装取排水头部；挡水钢筒的底端与沉箱的顶端可拆卸地固定连接，挡水钢筒的顶端延伸至海平面上方的高度不小于预设高度，挡水钢筒用于防止海水进入沉箱内。
