Strengthening Structure and Construction Method of Highway Subgrade

Abstract

The invention discloses a highway subgrade reinforcing structure and a construction method. The highway subgrade reinforcing structure comprises a drainage part, a first reinforcing layer, a second reinforcing layer and a control part; the first reinforcing layer is arranged at the bottom end of a highway subgrade, the first reinforcing layer comprises a plurality of reinforcing bottom plates anda first concrete layer on the reinforcing bottom plates, each reinforcing bottom plate comprises a box body and a cover plate, a first opening is formed in the top end of each box body, a plurality ofrows of first pipe bodies are arranged in each box body, and the first pipe bodies are in butt joint with the drainage part through second pipe bodies; a column body is arranged between the first pipe bodies, and concrete is poured into the box body; the cover plate is buckled at the top end of the box body; concrete is poured inside and outside the column body; the second reinforcing layer is arranged at the top end of the first concrete layer and comprises a lifting layer; and the control part comprises a controller and an intelligent settlement sensing module connected to the controller and is used for adjusting the vertical position of the block body so as to compensate settlement of the road surface. The highway subgrade reinforcing effect is improved, and meanwhile pavement settlement can be compensated for quickly in a small area.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a road bed reinforcement structure and a construction method. Background technique [0002] The subgrade is the foundation of the track or road surface, and it is a geotechnical structure formed after excavation or filling. The main function of the subgrade is to provide the necessary conditions for the laying of the track or road surface and the operation of trains or trains, and to bear the static and dynamic loads of the track and rolling stock or the road surface and traffic loads, and at the same time transfer and spread the load to the depth of the foundation. On the vertical section, the subgrade must ensure the elevation required by the line; on the plane, the subgrade is connected with bridges and tunnels to form a complete through-line. The situation, coupled with the impact and accumulation of rainwater, etc., lead to the subsidence of many small areas in th...

AI Technical Summary

Problems solved by technology

On the vertical section, the subgrade must ensure the elevation required by the line; on the plane, the subgrade is connected with bridges and tunnels to form a complete through-line. In addition to the impact and accumulation of rainwater, many small areas of subsidence have occurred in the subgrade, which has caused major safety hazards for driving. It is necessary to provide a road subgrade reinforcement structure and construction method
