Novel embankment foot scour prevention structure
The invention relates to the technical field of embankment foot structures, and discloses a novel embankment foot scour prevention structure which comprises plastic steel sheet piles and prefabricated reinforced concrete piles, the plastic steel sheet piles and the prefabricated reinforced concrete piles are transversely clamped and inserted into the ground at intervals, a pouring seam is formed between every two adjacent prefabricated reinforced concrete piles, and pouring filler is poured and fixedly arranged in the pouring seams; the plastic steel plate pile is inserted in the side away from the outer river side, the front end face of the plastic steel plate pile is tightly attached to the side wall of the prefabricated reinforced concrete pile, a plain concrete cushion layer is poured on the upper layer of the prefabricated reinforced concrete pile, and a rock ballast cushion layer is poured on the upper layer of the plain concrete cushion layer. The high-strength prestressed sheet piles are densely arranged on the road, the excellent bending resistance of the high-strength prestressed sheet piles is fully exerted, and the high-strength prestressed sheet piles are used for resisting dyke foot scouring caused by outer side flood in the operation period; a plastic steel sheet pile is tightly attached to the inner side of the densely-arranged sheet piles, through combined defense of the plastic steel sheet pile and the densely-arranged sheet piles, the problem that earthwork in joints of traditional sheet piles is prone to loss can be effectively solved under the condition that the investment is not increased too much, and the safety of the dyke foot vertical anti-scour structure can be remarkably improved.
本发明涉及堤脚结构技术领域，公开了一种新型堤脚防冲结构，本发明包括塑钢板桩和预制钢筋砼桩，横向间隔卡接且插装于地面内，相邻两个预制钢筋砼桩之间形成有浇筑缝，在浇筑缝内浇筑固定设有浇筑填料，塑钢板桩插装在远离外江侧的一侧，塑钢板桩的前端面紧贴在预制钢筋砼桩的侧壁上，预制钢筋砼桩的上层浇筑设有素砼垫层，素砼垫层的上层浇筑设有石渣垫层。本发明通过在道密排高强度预应力板桩，充分发挥其优良的抗弯性能，用来抵抗运行期外侧洪水引起的堤脚冲刷；紧贴密排板桩内侧设一道塑钢板桩，通过二者联合防御，在增加投资不多的情况，可以有效解决传统板桩接缝间土方容易流失的问题，可以显著提高堤脚垂直防冲结构的安全性。
