Unbonded prestressed reinforced earth construction method and device thereof

Abstract

The invention provides an unbonded prestressed reinforced earth construction method and a device thereof. The method comprises the following steps of: preliminarily connecting a reinforcement material with a first-layer baffle plate through an anchor device, and preliminarily fixing the first-layer baffle plate through the reinforcement material; continuously filling earth and compacting till a second layer is laid in the height position of the reinforcement material, laying the unbonded prestressed reinforcement material, and fixing the reinforcement material with a second-layer baffle plate according to the same method with the first layer; sequentially performing the operation till the completion of filling of a whole earth bank or a side slope; and finally applying prestress on the unbonded prestressed reinforcement material of each layer. The device comprises the unbonded prestressed reinforcement material and the anchor device, and the unbonded prestressed reinforcement material and the anchor device are mutually connected. The unbonded prestressed reinforced earth construction method is of a geotechnological reinforcement method with the combination of active and passive ways, and the purposes of increasing the strength of the filled earth and controlling and regulating the vertical deformation of the filled earth can be achieved through the interaction among the reinforcement material, the baffle plates as well as the anchor device and the filled earth.

Description

technical field [0001] The invention relates to a non-adhesive prestressed reinforced soil construction method and equipment thereof, belonging to the technical field of geotechnical reinforcement. Background technique [0002] In the field of geotechnical reinforcement technology, the existing mainstream reinforced soil technology is to lay reinforcement materials horizontally in the fill to achieve the purpose of restraining 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, research and development of reinforced materials, such as geogrids, geocells, geotextiles, galvanized steel strips, steel-plastic strips, concrete steel strips, etc.; on the other hand, research an...

AI Technical Summary

Problems solved by technology

[0014] The purpose of the present invention is to solve the problem that there is no connection between the unbonded prestressed reinforced strips of the same layer, the deformation of the soil between the reinforced strips cannot be coordinated, the prestress on the internal reinforced materials cannot be controlled, and the The secondary tensioning of the reinforced material and the adjustment of the internal force of the internal ribs are provided to provide a non-adhesive prestressed reinforced soil construction method and its equipment
