Water-saving ecological slope protection structure and construction and water-saving method thereof

Abstract

The invention belongs to a water-saving ecological slope protection structure and a construction and water-saving method thereof. The structure comprises left diversion dams and right diversion dams which are distributed at spacing distance and are arranged at intersections of transverse drainage channels and longitudinal drainage channels, wherein the left diversion dams and the right diversion dams are arc-shaped dam bodies; the front ends of the left diversion dams and the right diversion dams are located in the longitudinal drainage channels and divide the inflow cross sections of the longitudinal drainage channels into middle drainage ports, left water-saving channel inlets and right water-saving channel inlets; and the rear ends of the left diversion dams and the right diversion damsare located in the transverse drainage channels of the left sides and right sides of intersections of the drainage channels. The method comprises the step of carrying out alkalization removal treatment on a concrete baffle plate and concrete casting ground. The water-saving ecological slope protection structure can effectively utilize natural water resources to provide an environment suitable for plant growth, and has the advantages of reasonable structural design, simple and practical method, long service life and good stability of slope protection.

Description

technical field [0001] The invention belongs to a water-saving ecological slope protection structure and its construction and water-saving methods. Background technique [0002] In the roadbed slope protection of roads and railways, in order to stabilize the inclined slope protection, the slope protection surface is usually divided into rectangular grid mesh surfaces with cast-in-place concrete baffles. The inner area of ​​each grid is 5-25m². In the nursery, soil-fixing plants are planted inside the grid to prevent soil erosion in slope protection. Therefore, the requirement for concrete baffles is to not only achieve durable and stable slope protection, but also adapt to various planting methods and meet the design requirements of the ecological environment. However, due to the hydration reaction of cement, alkaline substances such as calcium hydroxide and high-alkalinity calcium silicate hydrate will be formed on the surface of concrete after hardening, resulting in an a...

AI Technical Summary

Problems solved by technology

However, due to the hydration reaction of cement, alkaline substances such as calcium hydroxide and high-alkalinity calcium silicate hydrate will be formed on the surface of concrete after hardening, resulting in an alkaline internal water environment, which cannot meet the pH requirements of the plant growth environment.

In order to ensure that the roots of concrete plants can pass through the concrete layer, the porosity must be large and the pore diameter reasonable, while not affecting its own strength. The existing concrete construction cannot meet the requirements.

Dividing the slope protection surface into a rectangular grid mesh surface cannot use natural water resources to effectively irrigate and discharge floods to the plants in the grid. Heavy rains wash away slope protection, and light rain often causes plants in the grid to die due to lack of water.
