Flexible ecological spur dike system
The invention discloses a flexible ecological spur dike system. The flexible ecological spur dike system comprises a spur dike body, the spur dike body is connected with a bank on the horizontal plane to form a T shape and comprises an arc jetty head, an arch dike body and a bank-connection dike root in sequential connection, and the bank-connection dike root is connected to the bank through stairs; an included angle formed by the spur dike body and a downstream water flow direction is smaller than 90 degrees; on the longitudinal section, the spur dike body comprises a reinforced earth dike core, a flexible ecological dike slope, dike toe slope pressure parts and a water affinity platform, the flexible ecological dike slope covers the reinforced earth dike core, dike toe portions on two sides of the flexible ecological dike slope are filled by the dike toe slope pressure parts by means of dumping fill, and the water affinity platform is arranged on the top of the flexible ecological dike slope. The flexible ecological dike slope comprises waste tire reinforced planting soil, geogrids and aquatic plants in hierarchical staggered stacking arrangement. By adoption of waste tires for construction of the spur dike system with dual functions of flexibility and ecology, utilization rate of the waste tires is greatly increased, resource regeneration is realized, and construction cost is saved; in addition, conformance to river regimes, decrease of ship collision accident rate and providing of the ecological plant platform are realized.
