The stepped water-cut wall is convenient to construct, but compared with other structures, the stepped water-cut wall has the advantages of good mechanical properties, more material waste and poor stability. And the water interception wall and the water interception ditch structure both relate to permanent occupation of land, can influence the farming planting in the side slope, and the vegetation growth of the slope can be destroyed by the water interception wall protruding out of the ground. Based on the defects, a pipeline restoration ecological protection structure is needed, soil loss in a pipe ditch can be effectively prevented, the structure is stable, and vegetation planting on a slope is not affected.
