Abstract

The invention provides a vegetation mesh revetment method comprising the following operation steps of: (1) tidying up a riverside, and making the riverside into a slope surface lower than 70 degrees; (2) arranging a roof bolt on the slope surface; (3) paving galvanized wire meshes along the slope surface, and fixing the meshes on the roof bolt by binding wires; (4) preparing a revetment ground substance; (5) jetting the revetment ground substance to the slope surface; (6) paving a vegetation mesh on the surface of the step (5) along the slope surface; (7) paving the galvanized wire meshes on the surface of the step (6) along the slope surface and fixing; and (8) watering and carrying out later maintenance management. The invention has simple process and high mechanical degree, can sufficiently protect the stable structure of bank slopes, reduce seed loss on bank slopes, and ensure the good growth of vegetation on bank slopes. The invention is mainly used for the green management of bank slopes.

Description

technical field [0001] The invention relates to a river bank greening method, in particular to a planting net bank protection method. Background technique [0002] River revetment works are an effective measure to prevent river bank collapse and soil erosion. They have played an important role in flood control and maintaining river regime stability over the years, and have become an important part of flood control system and river regime control planning. Bank revetment includes underwater bank revetment and water bank revetment. Water bank revetment includes slope cutting and masonry, concrete pouring, etc. Although these methods can protect bank slopes and maintain river stability, they are safe, economical and effective from the perspective of traditional engineering, but bank revetment at the same time It also destroys the natural vegetation on the original bank slope, causing the river to present a gray corridor landscape, seriously affecting the healthy development of ...
