Irrigation-drainage ditch slope revetment device for coastal reclamation areas

Abstract

The invention discloses an irrigation-drainage ditch slope revetment device for coastal reclamation areas, which comprises a hard retaining plate and a soft revetment. The hard retaining plate is disposed on the inner side of a slope and is perpendicular to the ground. The soft revetment matched with the slope in inclination is disposed on the outer surface of the slope. One end of the soft revetment is connected with the top end of the hard retaining plate, and the other end of the soft revetment is fixed to the bottom of the slope. The soft revetment comprises a mesh layer and a geotextile layer, the geotextile layer is laid flat on the outer surface of the slope, and the mesh layer is disposed on the outer side of the geotextile layer. By means of the irrigation-drainage ditch slope revetment device, deformation, collapse and deposition of soil slopes of drainage ditches in soil improvement for coastal reclamation areas can be improved effectively, and the geotextile layer with an anti-seepage function enables smooth drainage, salt leaching and irrigation. The irrigation-drainage ditch slope revetment device is convenient in assembly and disassembly, reusable and reclaimable and suitable for different sizes and types of cross sections, and meets the irrigation-drainage ditch slope requirements in soil improvement for coastal reclamation areas.

Description

technical field [0001] The invention relates to a slope protection facility in a coastal reclamation area, in particular to a slope protection device for irrigation and drainage ditches in a coastal reclamation area. Background technique [0002] Land reclamation from the sea has a long history in our country. As early as the Han Dynasty, there were records of land reclamation from the sea. The Netherlands has a history of nearly 800 years of land reclamation from the sea. Countries in the world with insufficient land resources, such as Singapore, Japan and South Korea, have adopted the strategy of reclamation from the sea. In the 1960s and 1970s, a large number of tidal flats were reclaimed along the eastern coast of my country to expand agricultural land. With the rapid development of the economy, the contradiction of the shortage of land resources has become more and more prominent, and many coastal areas have proposed land reclamation plans. The long-term continuous re...

Problems solved by technology

[0005] In order to overcome the problems existing in traditional slope protection technology, the purpose of the present invention is to provide a slope protection device for irrigation and drainage ditches in coastal reclamation areas, which can effectively solve the problems of easy deformation, collapse and deposition of soil drainage ditch slopes in coastal reclamation areas, and extremely serious water and soil loss. It also has anti-seepage effect, and can carry out drainage, salt washing and irrigation smoothly
