Abstract
The invention relates to a method for repairing geocells and side slopes. Each geocell comprises at least two bent earth stripes which stick to each other, wherein at least two rows of through holes are formed in the middle part of each soil stripe; joints of the soil stripes stick to one another to form a fixed hole perpendicular to the ground; an anchor rod nailed into the soil is arranged in the fixed hole; binding holes perpendicular to the soil stripes are formed in the soil stripes on two sides of the anchor rod; solder wires used for foxing the soil strips and the anchor are formed in the binding holes. By virtue of the geocells, root systems of plants can be effectively communicated with one another among the geocells; all independent geocells are combined to be a whole body by the root systems, so that a good reinforcing function is achieved; furthermore, the connection manner of the soil strips is changed, so that the geocells are fixed by the anchor rod; by virtue of the cooperation of the geocells and an improved construction method, the problem of side slopes formed due to soil wind erosion caused by insufficient vegetation coverage or dry grass periods can be solved.
