Base improvement and ecological rehabilitation method for windward side embankment

Abstract

The invention discloses a base improvement and ecological rehabilitation method for a windward side embankment. The base improvement and ecological remediation method comprises the following steps: A, area selection; B, slope flattening and ramming; C, ecological concrete preparation, including stirring and mixing river sand, crushed stones, cement, water, blending agents and chemical additives in proportion to prepare ecological concrete; D, improved soil preparation, including mixing minerals and detritus into red soil; E, base improvement and ecological rehabilitation under a normal water level, including paving ecological concrete members; F, base improvement and ecological rehabilitation between the normal water level and a flood level, including paving cast-in-place ecological concrete; G, base improvement and ecological rehabilitation above the flood level, including paving stone, filling concrete holes and stone gaps with soil, and planting vegetation in the concrete holes and the stone gaps; H, base improvement and ecological rehabilitation at the top of the windward side embankment, including paving sandy soil and planting vegetation; and I, maintenance and management. The base improvement and ecological rehabilitation method provided by the invention is convenient to operate and low in investment and operation management cost, realizes multiple effects such as embankment stabilization, landscape greening and pollutant interception, and has important environmental, social and economic benefits.

Description

technical field [0001] The invention belongs to the field of lake ecological restoration, and more specifically relates to a method for base improvement and ecological restoration of windward embankments, which is suitable for base improvement and ecological restoration of windward embankments such as lakes, rivers, reservoirs, and ponds. Background technique [0002] In China, hard embankments are mostly built on the windward side or water body shorelines with large scouring capacity. The purpose is to prevent the soil matrix inside the embankment from being eroded, washed out or even collapsed by the action of wind and waves, so as to ensure the stability of the embankment. However, the hard embankment is not easy for the growth of vegetation and the reproduction of small animals, resulting in sparse vegetation, low species diversity, fragile ecosystem, poor ecological landscape effect, and almost zero buffering capacity for pollutants flowing through the embankment, thus a...

Problems solved by technology

For slopes that are prone to landslides due to deep instability, reinforced concrete is used to form the frame, and engineering measures to reinforce the slope with anchor rods or anchor cables are combined with vegetation slope protection, but there is often a contradiction between the stability of the embankment and plant restoration.
