Multi-dimensional filler ecological type protected slope construction method suitable for repairing riverways in towns

Abstract

The invention relates to a multi-dimensional filler ecological type protected slope construction method suitable for repairing riverways in towns. The method comprises the following steps of: taking an ecological bag structure as a support; dividing a protected slope structure into four areas: an upright protector area, a low water level influence area, a normal water level influence area and a maximum flood level influence area; selecting matrixes adapted to structures and functions of the areas as fillers; recovering submerged plants, emergent aquatic plants and wetland plantsbog plants on a protected slope from bottom to top; and simultaneously, setting facilities such as a buffering platform and a domestic sewage distribution pipe, and constructing a zigzag river corridor. According to the multi-dimensional filler ecological type protected slope construction method suitable for repairing the riverways in the towns, the mechanical stability of the slope can be improved, the anti-erosion performance of the protected slope of a river is enhanced; the living condition of a river waterside variation area is effectively recovered, and the completeness of a river ecological system is ensured; and the matrixes of the protected slope, microorganisms and vegetation have important interception conversion effect on coastwise non-point source pollution, so that the river self-cleaning capacity is enhanced, the service function of a river ecological system is improved, materials are selected according to circumstances, the construction is simple and convenient, the manufacturing cost is low, and wide market value and environmental benefit are realized.

Description

technical field [0001] The invention relates to the technical field of engineering protection structures, in particular to an ecological slope protection construction method with multi-dimensional fillers suitable for village and town river restoration. Background technique [0002] From the "Ninth Five-Year Plan" to the present, the country's attitude towards river water resources management has gone through the following three stages: (1) Emphasis on water conservancy facilities and the economic benefits of developing water energy; (2) Adhere to the combination of promoting benefits and eliminating harm, flood control and drought relief Simultaneously; (3) Intensify the prevention and control of water pollution in key river basins and regions, emphasizing the improvement of the ecological environment of rivers. However, in terms of its overall work, my country is still in the stage of river water quality restoration. In recent years, many domestic scholars have begun to p...
