Prefabricated interlocking block slope protection system suitable for downstream dam slope of silt dam
The invention provides a prefabricated interlocking block slope protection system suitable for the downstream dam slope of a silt dam. The prefabricated interlocking block slope protection system comprises a slope protection body, wherein the slope protection body comprises geotechnical cloth which is laid on the downstream dam slope surface of the silt dam and a plurality of prefabricated blocks which are laid on the geotechnical cloth, and the plurality of prefabricated blocks are mutually interlocked and extend along the longitudinal direction and the vertical direction of the downstream slope surface of a dam body so as to form an interlocked integral slope protection structure. The prefabricated interlocking block slope protection system is used for the downstream slope surface of the silt dam, so that water passing of the silt dam is realized, and the problem that over-standard flood easily breaks the dam can be effectively solved. Due to the unique shape of the prefabricated blocks, the whole slope protection has certain flexibility and can adapt to differential settlement and local deformation of the dam body; and the slope protection structure has super-strong interlocking property, so that the overall stability of the slope protection structure is guaranteed. The flip bucket on the upper surface of prefabricated block webs has the effect of step energy dissipation, so that the flow velocity of discharged water flow is reduced, and scouring to the slope surface is reduced. The geotechnical cloth is laid on the lower layer of the prefabricated block slope protection, so that the effects of inverted filtration and drainage can be achieved, and stabilization of the dam slope is facilitated.
本发明提供了一种适用于淤地坝下游坝坡的预制连锁块护坡系统，包括护坡本体，护坡本体包括：土工布，铺设在淤地坝下游坡面上；若干个预制块，铺设在所述土工布上，所述若干个预制块相互嵌锁，沿坝体下游坡面纵向和竖向延伸形成连锁的整体护坡结构。本发明用于淤地坝下游坡面，从而实现淤地坝过水，能够有效解决超标准洪水易溃坝的问题。预制块独特的造型使得整个护坡既具有一定的柔性，能够适应坝体的不均匀沉降和局部变形；又具有超强的连锁性，保证护坡结构的整体稳定。预制块腹板上表面的挑坎能够起到台阶消能的作用，使得下泄水流流速降低，减小对坡面的冲刷。预制块护坡下层铺设土工布，能够起到反滤排水的作用，有利于坝坡的稳定。
