Soft soil area reinforced gravel pile supporting EPS light embankment structure and construction method thereof

Abstract

The invention belongs to the field of roadbed engineering, and relates to a soft soil area reinforced gravel pile supporting EPS light embankment structure and a construction method thereof, wherein the soft soil area reinforced gravel pile supporting EPS light embankment structure comprises bidirectional reinforced gravel piles, a drainage ditch, a geotechnical cloth cushion layer, a high-strength load transmission platform, a waterproof roll, edge covering soil, EPS foam blocks and a pavement structure layer; the bidirectional reinforced gravel piles are arranged in a pile group mode, are distributed in a square mode and are longitudinally arranged in a soft soil foundation; and the geotechnical cloth cushion layer, the high-strength load transfer platform, the waterproof roll and a second high-strength load transfer platform are sequentially laid on the top of the bidirectional reinforced gravel pile from bottom to top, the EPS foam blocks are filled in a layered mode, and finally a pavement structure layer is laid. The strength of the foundation is improved, the EPS foam block is used as the embankment filler, the dead weight of the embankment and the overlying load of the foundation soil are remarkably reduced, the overall stability of the structure is remarkably enhanced through the high-strength load transfer platform, and the defects that the foundation of the embankment built on the soft soil foundation is large in settlement, poor in stability and the like can be effectively overcome.

Description

technical field [0001] The invention belongs to the field of roadbed engineering, and relates to an EPS light embankment structure supported by reinforced gravel piles in soft soil areas and a construction method. Background technique [0002] When building an embankment on a soft soil foundation, it is necessary to consider the influence of the overlying load on the foundation settlement and uneven settlement. The usual method is to treat the foundation to improve the bearing capacity of the foundation; the reinforced gravel pile is a comparative Effective soft soil foundation reinforcement method, simple construction, low cost, can also speed up construction on the basis of ensuring a certain bearing capacity; for soft soil foundations with poor geological conditions, reinforced gravel piles can be reinforced to a certain extent Improve the strength of the foundation, but its reinforcement depth and reinforcement strength have certain limitations. Under the embankment load...

[0002] When building an embankment on a soft soil foundation, it is necessary to consider the influence of the overlying load on the foundation settlement and uneven settlement. The usual method is to treat the foundation to improve the bearing capacity of the foundation; the reinforced gravel pile is a comparative Effective soft soil foundation reinforcement method, simple construction, low cost, can also speed up construction on the basis of ensuring a certain bearing capacity; for soft soil foundations with poor geological conditions, reinforced gravel piles can be reinforced to a certain extent Improve the strength of the foundation, but its reinforcement depth and reinforcement strength have certain limitations. Under the embankment load, the foundation will also produce certain settlement and instability deformation, especially for high-fill embankment construction, often resulting in large settlement and poor stability.
