Treatment method for underwater slope in vegetation dense area

Abstract

The invention discloses a treatment method for an underwater slope in a vegetation dense area, which comprises the following steps: cutting off crowns of trees on the slope below a normal water storage level, only retaining trunks and roots, and enabling the tops of the trunks to be lower than the normal water storage level; making a slope foot presser foot at the bottom of the slope; cleaning weeds and gravels on the surface of the side slope, laying geotextile on the side slope with trunks and roots reserved, throwing and filling a layer of waste slag on the geotextile, laying a layer of geogrid on the waste slag, throwing and filling the waste slag, repeatedly laying the geogrid, throwing and filling the waste slag, building large stones on the waste slag layer, and enabling the trunks to penetrate out of the surfaces of the large stones. The intricate distribution state of tree root systems in soil is equivalent to a good natural reinforced material; in addition, the isolation, filtration, drainage, reinforcement and protection effects of the overlying geotechnical cloth form a very good anti-filtration protection effect so as to make up the loss of the stability coefficient after the side slope is soaked in water, so that the side slope can be kept stable under the condition of being soaked in reservoir water.

Description

technical field [0001] The invention relates to a treatment method for underwater slopes, in particular to a treatment method for underwater slopes in areas with dense vegetation. Background technique [0002] The distribution of China's water resources is more in the south than in the north, and the water resources are mainly concentrated in the southwest region, of which the Yangtze River system is the most. River slopes in densely vegetated areas tend to have thick covering layers and lush vegetation. After the reservoir is impounded, if it is not treated, it will easily cause slope instability. Traditional treatment schemes often use methods such as large excavation or anti-slide piles, anchor cables + frame beams, etc. The construction is difficult, the process is cumbersome, the construction period is long, and the investment is large. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a treatment method for ...
