Earth and rockfill dam anti-seepage water stop structure
The invention belongs to the technical field of earth and rockfill dams, and discloses an earth and rockfill dam anti-seepage water stop structure which comprises a weakly-weathered foundation and a strongly-weathered foundation, a rock-fill layer is arranged on the top of the strongly-weathered foundation, and a core wall is arranged in the middle of the rock-fill layer. The metal pipe is connected in the concrete pile in a sleeved mode, the outer surface of the metal pipe fixedly communicates with the annularly-distributed side pipes, the filter element sleeve is additionally arranged in the metal pipe, suction of the interior of the communicating frame is achieved in cooperation with the suction box at the top of the core wall, and therefore air in the inner pipe is sucked in cooperation with the communicating pipe, and under the condition that the air pressure in the inner pipe is reduced, the air pressure in the inner pipe is reduced. The air in the core wall is sucked into the side pipe and sucked into the inner pipe through the filter element sleeve and the filter holes, so that clay is gradually adsorbed and drawn close by reducing the air pressure in the core wall, the internal density of the core wall is enhanced, and the permeation condition caused by density reduction due to looseness is avoided; therefore, the core wall can still have a good anti-seepage and water-stopping effect after being used for a certain period of time.
本发明属于土石坝技术领域，且公开了一种土石坝防渗止水结构，包括弱风化地基和强风化地基，所述强风化地基的顶部设有堆石层，所述堆石层的中部设有心墙。本发明通过在混凝土桩中套接金属管，且在金属管的外表面固定连通环形分布的侧管，并在金属管的内部增设滤芯套，配合心墙顶部的抽吸箱实现对连通框内部的抽吸，从而配合连通管抽吸内管中的空气，在内管内部气压减小的情况下，使得心墙内部空气吸入至侧管中，并通过滤芯套和滤孔吸入至内管中，从而通过减小心墙内部气压，使得黏土逐渐吸附靠拢，从而加强心墙的内部密度，避免松弛造成的密度减小而带来渗透情况，从而保证了使用一定年限后心墙任然可以具有良好的防渗止水效果。
