Temporary plugging method for deepwater horizontal tunnel
The invention discloses a temporary plugging method for a deepwater horizontal tunnel, which realizes the plugging of the underwater horizontal tunnel through a series of technical measures such as underwater exploration, plugging gate design and installation, process safety monitoring and the like. The method specifically comprises the following steps of: 1, carrying out underwater exploration, and completely reappearing the condition of an underwater tunnel; secondly, a blocking gate is designed and manufactured according to the underwater exploration result, the structural design of the blocking gate is optimized, and the blocking gate is easy to transport and install in the underwater horizontal tunnel; thirdly, a plugging gate is installed, specifically, the plugging gate is installed at the corresponding position, and plugging of the underwater tunnel is achieved; fourthly, the plugging gate is dismantled; the sealing face of the gate body is sealed through rubber, and self-sealing is achieved through water pressure. When the gate is assembled and disassembled underwater, water or air is controlled to be injected into the floater, the dead weight of the gate is changed, then the underwater state of the gate is controlled, the gate sinks, suspends or ascends, and underwater construction and transportation of the gate are facilitated.
本发明公开了一种深水水平隧洞临时封堵方法，经过水下探查、封堵闸门设计及安装、过程安全监护等一系列技术措施，实现水下水平隧洞封堵；具体工作流程是：第一步进行水下探查，将水下隧洞的情况进行完整的重现；第二步是根据水下探查结果进行封堵闸门的设计和制造，优化封堵闸门结构设计，使其在水下水平隧洞内运输和安装操作简单；第三步是封堵闸门的安装，将封堵闸门安装到对应位置，实现水下隧洞的封堵；第四步是封堵闸门的拆除；所述闸门主体密封面采用橡胶密封，利用水压实现自密封；在闸门水下安装和拆卸施工时，通过控制浮子内注水或空气，改变闸门自重进而控制闸门在水下的状态，是处于下沉、悬浮或上升，方便闸门的水下施工和运输。
