Dam fixing and protecting construction method using soil stabilizer in land reclamation project

Abstract

The invention discloses a dam fixing and protecting construction method using a soil stabilizer in a land reclamation project. The method comprises the steps of preparing a dry and hard mixture from the soil stabilizer, soil and water, and then compacting the mixture under a condition of supporting and protection of a template to form a scour prevention barrier wall. The scour prevention barrier wall prepared based on the method disclosed by the invention makes full use of local land and water resources, has a low requirement for soil quality and water quality, can neither affect planting on the surface land nor affect greening of a high and steep slope, can be used for 15 to 20 years, has an effect which is basically the same with that of a concrete barrier wall, and is pollution-free to the environment; the construction cost of the scour prevention barrier wall is only 1 / 3 of the cost of the concrete barrier wall, and the scour prevention barrier wall is relatively high in cost performance ratio; and the construction is relatively simple and convenient, and the construction cost is reduced. The method can be widely applied to land reclamation in the wide loess plateau and other sand and gravel-free districts as well as scour prevention of a steep side slope and a warp land dam, and has an important practical significance for healthy development of the land reclamation in mountainous areas.

Description

technical field [0001] The invention belongs to the technical field of land improvement engineering, water conservancy and water conservation, and ecological environment construction engineering, and mainly relates to materials and techniques for building embankment protection facilities, especially a kind of land improvement for land improvement projects in hilly and gully areas of the Loess Plateau or other hilly mountainous areas. The construction method of engineering soil curing agent for embankment reinforcement and embankment protection is applicable to dike reinforcement and embankment engineering for land improvement, check dams, river embankments and the like. Background technique [0002] In the Loess Plateau area, the project of "converting farmland to forest (grass)" was implemented, and a large number of cultivated lands were covered with green clothes, and the ecological environment was greatly improved. At the same time, the shortage of land resources was high...

AI Technical Summary

Problems solved by technology

However, with the implementation of the land improvement project, a large number of high and steep slopes of terraces have been formed. In case of heavy rain, gullies will be formed, causing serious soil erosion and threatening the construction of high-quality land.
