Construction method of ecological revetment for river bank protection

Abstract

The invention discloses a construction method of an ecological revetment for river bank protection. The construction method comprises the following steps of a, paving a gravel material cushion layer;b, paving geotechnical cloth; c, backfilling a soil layer with the depth of 20-30 cm on the geotechnical cloth, and compacting the soil layer; d, constructing the ecological revetment; and e, placingsoil into ecological planting holes of ecological building blocks, and then growing plants. According to the construction method, the ecological building blocks after construction cannot fall off, sothat the overall performance of the whole ecological revetment is improved, and the flood prevention effect, the ecological effect, the landscape effect and the self-cleaning effect of the ecologicalrevetment are enhanced; and meanwhile, accumulated water on the construction site can flow into the inclined surface parts of the ecological building blocks through filter plates used for lapping withthe building blocks, and the water on the inclined surface parts of the ecological building blocks are discharged into the soil through drainage grooves, so that the earthwork of the construction area which is not paved with the ecological building blocks is prevented from being subjected to micro-amplitude sedimentation phenomenon, the flatness of the excavated earthwork is guaranteed, the ecological building blocks can be conveniently and quickly laid, moreover, the ecological building blocks can be quickly replaced, and the service period of the ecological revetment can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of river regulation engineering, and in particular relates to a construction method for ecological bank protection for river bank protection. Background technique [0002] Ecological restoration refers to stopping human disturbance to the ecosystem to reduce load pressure, relying on the self-regulation and self-organization capabilities of the ecosystem to make it evolve in an orderly direction, or using the self-recovery ability of the ecosystem, supplemented by Artificial measures to gradually restore the damaged ecosystem or make the ecosystem develop in a virtuous cycle; mainly refers to the restoration and reconstruction of the natural ecosystem that has been damaged by natural mutations and human activities, and restores the ecosystem. The original appearance. [0003] Ecological river restoration is one of the fields of ecological restoration. At present, ecological revetments are used to restore ec...

Problems solved by technology

In the prior art, during the construction of ecological revetment, ecological blocks are used to build masonry on the slope, and the two adjacent ecological blocks in the horizontal direction and the two adjacent ecological blocks in the vertical direction are fixedly connected by concrete. The construction method With a certain construction period, the construction area without ecological blocks is easy to accumulate water, resulting in slight settlement of the earthwork in the construction area without ecological blocks, and after the construction is completed, the ecological blocks are washed by the river. Ecological revetments are prone to falling off of ecological blocks, which affects the integrity of the entire ecological revetment and weakens the flood control effect, ecological effect, landscape effect and self-purification effect of ecological revetment
