Siltation promotion sand rib soft mattress for seawall engineering
The invention provides a siltation promotion sand rib soft mattress for seawall engineering, and relates to the technical field of hydraulic engineering, the siltation promotion sand rib soft mattress for seawall engineering comprises a geotechnical cloth layer distributed on a seawall, connecting strips distributed in rows are arranged on the upper side of the geotechnical cloth layer, sand rib columns and ballast strips are pressed on the connecting strips, a plurality of sand rib columns are distributed between the ballast strips, and the sand rib columns and the ballast strips are arranged in parallel. A reinforced belt is fixed on the connecting strip, an elastic strip is fixed at the other end of the reinforced belt, and the reinforced belt and the elastic strip wrap the sand rib column and press the sand rib column to the connecting strip. After siltation promotion and sand rib soft mattress protection surface construction are completed, the water depth near a seawall is obviously reduced, namely, the siltation depth is continuously increased, the siltation promotion effect is good, under the combined action of energy impact reduction and reverse filtration of the sand rib soft mattress, the water flow velocity is further reduced, the siltation promotion influence range is gradually enlarged, and the siltation promotion effect is greatly improved. The curve fluctuation of the water depth in the near-dike range along with the time change is larger than that of the far-dike range, the siltation promotion effect is more obvious near the dike body, and the maximum siltation depth can reach 2.0 m or above in the measurement time period.
本发明提供一种海堤工程用促淤型砂肋软体排，涉及水利工程技术领域，其包括分布于海堤上的土工布层，所述土工布层的上侧设置有成列分布连接条，所述连接条上压设有砂肋柱和压载条带，所述压载条带之间分布若干砂肋柱，所述连接条上固定有加筋带，所述加筋带的另一端固定有弹性条，所述加筋带和弹性条将砂肋柱包裹压向连接条。在促淤及砂肋软体排护面建设完成后，海堤附近水深均明显减小，即淤积深度不断增加，促淤效果较好，在砂肋软体排的削减能量冲击及反滤的共同作用下，水流流速进一步减小，促淤影响范围逐渐变大，近堤范围内水深随时间变化曲线波动较远堤更大，促淤效果在堤身附近更为明显，最大淤积深度在测量时间段内可达2.0m以上。
