Sluice downstream scour prevention structure
The invention discloses a sluice downstream scour prevention structure, and relates to the technical field of flood prevention equipment. The sluice downstream scour prevention structure specifically comprises a front wall, a rear wall, top beams, tie beams, dimension stones, composite geotechnical cloth and concrete precast blocks, wherein the front wall and the rear wall are composed of prefabricated concrete sheet piles, the front wall is located on the upstream of the downstream direction, and the rear wall is located on the downstream of the downstream direction; the top beams are arranged at the top ends of the front wall and the rear wall; the top beams are fixed through the tie beams, and one top beam is arranged between every two adjacent top beams at a set distance; the composite geotechnical cloth is made of woven cloth and non-woven cloth and is cushioned on a foundation soil layer or/and a scour prevention groove; and the concrete precast blocks are laid on the composite geotechnical cloth and are flexibly connected through polyvinyl chloride ropes. According to the sluice downstream scour prevention structure, by forming the scour prevention structure, the downstream scour prevention problem when the riverbed scour depth of a sluice downstream apron tail end outlet is large can be solved, and the safety of a sluice is guaranteed.
本发明公开了一种水闸下游防冲结构，涉及防洪设备技术领域，具体包括前墙、后墙、冠梁、系梁、块石、复合土工布和砼预制块；所述前墙和后墙由预制砼板桩组成，所述前墙位于顺水流方向的上游，所述后墙位于顺水流方向的下游；在前墙和后墙的顶端设有冠梁；所述冠梁之间通过系梁固定，冠梁之间每隔设定距离则设置一条冠梁；所述复合土工布由机织布和无纺布制作，垫于地基土层或/和防冲槽之上；所述砼预制块铺设于复合土工布之上，由聚氯乙烯绳进行柔性连接。本发明通过形成防冲结构，能够解决闸下游海漫末端出口的河床冲刷深度较大时下游的防冲问题，保证水闸安全。
