Abstract

The invention discloses a land-side slope shoulder protection structure and a construction method thereof. The structure comprises a slope body, a concrete platform, a stone block layer, a material blocking device, a mould bag layer and a concrete foundation layer are arranged from top to bottom in the direction of the slope body, a concrete mixture is poured into the stone block layer in a spraying mode, the material blocking device comprises a material blocking plate, and the mould bag layer comprises geotechnical mould bags. The construction method comprises the steps that 1, the slope surface of the slope body is cleared up; 2, concrete pouring is conducted on the concrete platform and the concrete foundation layer simultaneously; 3, the geotechnical mould bags are laid; 4, the material blocking device is installed; 5, the material blocking plate is fixedly connected with the geotechnical mould bag located at the uppermost layer; 6, a soil back-filling layer is arranged; 7, stone blocks are placed in the stone block layer; 8, concrete is poured into stone block gaps formed in the stone block layer in a spraying mode; 9, the stone block layer is cured. According to the land-side slope shoulder protection structure and the construction method thereof, concentrated scouring of overtopping waves can be defended, the overtopping wave rate can be increased, the protection effect is good, the sea wave erosion defending strength is enhanced, and the service life of the slope surface is prolonged.

Description

technical field

[0001] The invention belongs to the technical field of backwater slope shoulder reinforcement, and in particular relates to a backwater slope shoulder protection structure and a construction method thereof. Background technique

[0002] In the practice of civil engineering production, with the construction and development of projects such as railways, highways, reservoir areas or sites, a large number of technical issues of slope engineering have been involved. The knowledge and achievements of soil engineering and soil mechanics have accumulated rich experience in slope engineering, and have made great progress and development in both theory and practice.

[0003] In recent years, with the extension and development of expressway construction to mountainous areas, due to its high technical level, difficult terrain conditions, complex geological structures, and fragile geological environment backgrounds in mountainous and coastal areas of our country, deep exc...
