Underwater plugging structure system for concrete faced rockfill dam
The invention discloses an underwater plugging structure system for a concrete faced rockfill dam. The underwater plugging structure system comprises a dam body, a face plate, a wave wall, a toe plate, curtain grouting and cracks generated in the face plate; reservoir water forms leaking water through the cracks generated in the face plate, a plugging pipe is erected on the face plate through a lantern ring, a material receiving hopper is arranged on the upper portion of the plugging pipe, a material receipting hopper is arranged on the lower portion of the plugging pipe, a feeding pipe is arranged on the lower portion of the material receipting hopper, the feeding pipe pours plugging materials into the dam body through a drill hole in the panel to block the leaking water, after the plugging materials block the leaking water of the dam body, the dam body is grouted through grouting equipment and a slurry conveying pipe arranged between the plugging pipe and the feeding pipe in the later period, and the leaking water of the dam body is completely blocked. According to the structure system, through an underwater plugging mode, a reservoir is prevented from being emptied, the repairing time is won, the dam safety is guaranteed, water resources are saved, and leakage of the concrete faced rockfill dam can be effectively plugged.
本发明公开了一种面板堆石坝水下堵漏结构系统，包括坝体、面板、防浪墙、趾板、帷幕灌浆及面板上产生的裂缝，库水通过面板上产生的裂缝形成渗漏水，堵漏管通过套环架设在面板上，堵漏管上部设有接料斗，堵漏管下部设有受料斗，受料斗下部设有给料管，给料管通过面板上的钻孔将堵漏料灌入坝体封堵渗漏水，待堵漏料将坝体渗漏水堵住之后，通过灌浆设备及后期设在堵漏管、给料管之间的输浆管对坝体进行灌浆，彻底封堵坝体的渗漏水。本结构系统通过水下封堵方式，避免了水库放空，争取了修复时间，保证了大坝安全，节约了水资源，并能有效的对面板堆石坝渗漏进行封堵。
