Shallow soft soil foundation foam light soil embankment structure and construction method

Abstract

The invention discloses a shallow soft soil foundation foam light soil embankment structure and a construction method, the shallow soft soil foundation foam light soil embankment structure comprises a cushion layer, a foam light soil foundation bed, a light protective wall, a protective wall foundation, a reinforced structure and an anti-seepage geomembrane, the cushion layer is located at the bottom layer of the embankment structure, the foam light soil foundation bed is arranged on the cushion layer, and the protective wall foundation is arranged on the cushion layer. The light protection wall is arranged on the protection wall foundation and encloses the foam light soil foundation bed, and the reinforced structure is arranged on the foam light soil foundation bed; the anti-seepage geomembranes are arranged on the bottom surface and the top surface of the foam light soil foundation bed; the foam light soil in the foam light soil foundation bed comprises cement, foam, slag powder and ceramic polishing slag powder. According to the embodiment of the invention, foam light soil is adopted to replace a conventional soft soil foundation replacement material, so that the dead weight of the foundation is effectively reduced, and overall structure settlement of the roadbed is reduced; the light protection wall has the effects of protecting light soil and preventing weathering, and the overall stability is improved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a shallow soft soil foundation foam lightweight soil embankment structure and a construction method. Background technique [0002] The purpose of the treatment of the soft soil subgrade is to improve the stability and bearing capacity of the road subgrade of this section. Soft soil subgrades are generally treated by sand cushion, civil grid layer and surcharged preloading. The reinforcement effect of this treatment is not very ideal. In addition, sometimes a row of pile walls is installed on both sides of the roadbed. Each row of pile walls is composed of a plurality of side piles arranged at intervals along a predetermined direction (that is, the length direction of the road subgrade). It is exposed outside, and it is easy to be pulled out of the original soft soil roadbed by external force and lost, making the pile wall useless. [0003] At present, most of the treatmen...

Problems solved by technology

Each row of pile walls is composed of a plurality of side piles arranged at intervals along a predetermined direction (that is, the length direction of the road subgrade). It is exposed outside, and it is easy to be pulled out of the original soft soil roadbed by external force and lost, making the pile wall useless

[0003] At present, most of the treatment methods after people improve the traditional methods need to use various devices and materials with complex structures. The production cost is very high, the implementation method is very complicated, and the construction is difficult. Difficult to promote
