Groove-shaped slope protection structure unit and application thereof

Abstract

A groove-shaped slope protection structure unit comprises a bottom plate, side walls and drainage holes, the bottom plate is formed by two supporting rods in a crossed mode, and supporting corners are arranged at the joints; the side walls are perpendicular to the bottom plate and arranged along the side lines of the bottom plate, and the side walls are arranged at the four ends of the bottom plate so as to form openings for water flow to pass through. The bottom plate and the side walls form a communicated groove-shaped structure; each side wall is provided with a plurality of side wall drainage holes, and the bottom plate is provided with a plurality of bottom plate drainage holes. According to the trough type slope protection structure unit and the application method thereof, when the water flow is small, water permeates into the plant growing area through the drainage holes, irrigation of the plant growing area is facilitated, and manual maintenance work is reduced; when the water flow is large, the drainage grooves with the elevation lower than the surface of the plant growing area are beneficial for rapidly draining excessive water, the situation that a large amount of water flows into the plant growing area is avoided, and matrix loss caused by soil body scouring of the plant growing area is reduced; the drainage holes are beneficial to rapidly draining excessive water in the soil to the slope toe, so that water accumulation in the plant growing area is avoided.

Description

technical field [0001] The invention belongs to the technical field of river course and coastal beach protection engineering, and relates to a slope protection engineering structure and method. Background technique [0002] In river course and coastal beach protection projects, when the water flow on the slope surface of the river channel or bank beach is large, the traditional concrete slope protection structure can play an effective protective role, but the structure lacks biological matrix and the ecological effect is poor. The existing ecological slope protection structure is often due to lack of effective drainage channels and excessive flooding, resulting in hypoxia in the soil, and the plant roots cannot get enough oxygen for respiration, which is not conducive to plant growth, and easily causes soil mass on the slope protection. If the substrate is lost, the vegetation area needs to be filled with soil regularly, and the later maintenance work is heavy. SUMMARY OF ...
