Flexible ecological spur dike system

Abstract

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.

Description

technical field [0001] The invention relates to an environment-protecting and revetment-type hydraulic structure, in particular to a flexible ecological spur dam system, which belongs to the field of water conservancy engineering. Background technique [0002] Groove dam, also known as T-shaped dam, is a common river channel coastal improvement structure that is orthogonal or oblique to the bank. In terms of river bank protection, spur dikes can prevent water flow from directly eroding the river bank to cause scour damage, and at the same time improve waterways, maintain river facies, and protect river water ecological diversity; in terms of coastal protection, spur dikes can block and weaken oblique waves and coastal waters. The erosion of the coast by the current will promote the siltation of the dam fields and form new beaches to achieve the purpose of protecting the coast. [0003] However, from the perspective of the function of spur dikes, traditional spur dikes have ...

Problems solved by technology

However, the spur dike of the above-mentioned rigid slope protection material shows strong rigidity. With the development of my country's waterway construction, it has become more and more a hidden danger to the navigation safety of small or even large ships. The collision of ships is a rigid collision without a buffering effect, which is easy to cause In recent years, there have been frequent reports of traffic accidents on the water; moreover, the requirements for materials are high, and the investment is large, some of which involve underwater construction, which directly leads to difficult construction; at the same time, it does not belong to the ecological river revetment, which contrasts greatly with the surrounding landscape , which is not conducive to the establishment and restoration of the river ecosystem
