Non-adhesion prestressing reinforcement material

Abstract

The invention provides a non-adhesion prestressing reinforcement material. A main stressed part comprises an internal reinforcement material and an outer layer reinforcement material; the internal reinforcement material is arranged inside the outer layer reinforcement material; the outer layer reinforcement material is made of polypropylene or polyvinyl chloride high molecular polymer; the internal reinforcement material is a high-elasticity modulus reinforcement material; and a lubricating agent is filled between the internal reinforcement material and the outer layer reinforcement material. According to the non-adhesion prestressing reinforcement material, the supporting effect of the reinforcement material on a soil body can be improved through the high-elasticity modulus reinforcement material in a tensioning inner layer. Therefore, the constraint of reinforcement belts on the soil body is increased, and the vertical deformation of filled earth is reduced; the non-adhesion prestressing reinforcement material can slide between the inner layer and an outer layer, so that the soil body cannot be driven to move towards the two sides in the tensioning process; and a composite material is formed by the outer layer reinforcement material and the soil body, so that the deformation of the soil body is further constrained. By mutually connecting a secondary stressed part with the main stressed part, the deformation of the soil body among the reinforcement belts on the same layer can be coordinated.

Description

technical field [0001] The invention relates to a non-adhesive prestressed reinforced material, which belongs to the technical field of reinforced materials. Background technique [0002] In the field of geotechnical reinforcement technology, the current mainstream reinforced soil technology is to lay reinforcement materials horizontally in the fill to achieve the purpose of constraining the fill, enhancing the strength of the fill, and reducing the deformation of the fill. It is usually used for foundation reinforcement, embankment (including road, railway), slope, retaining wall engineering, etc. [0003] At present, the development of this technology mainly focuses on the research and development of reinforced materials. On the one hand, the research and development of materials used in reinforced materials, such as various geogrids, various geocells, geotextiles, galvanized steel strips, steel-plastic strips, concrete steel strips, etc.; on the other hand, the form of r...

AI Technical Summary

Problems solved by technology

[0008] 2. There are defects in the reinforced material, and the filling butter between the inner and outer parts of the ribs is easy to lose

On the one hand, the loss of butter will increase the relative friction between the inner and outer parts, which will affect the uneven stress on the entire galvanized steel strip; on the other hand, the loss of butter will cause pollution to the soil

[0009] 3. The corresponding anchoring device cannot perform secondary tension and prestress adjustment
