Abstract

The invention discloses a structure and construction method of EPS lower embankment. The structure of EPS lower embankment mentioned is a novel EPS lower embankment structure composed of a sandwich structure taking advantages of cement modified soil (9) soil material, EPS (2) material and geogrid (4) material. Compared with the existing similar embankment structure and construction method, the novel structure and construction method of EPS lower embankment provided by the invention have the advantages of higher integral rigidity of the embankment, stronger coordination effect on settlement deformation after soft soil foundation construction, lower cost and simple construction technology, and are particularly suitable for lower embankments construction of low-grade highways in middle and deep soft soil foundation sections of the coastal and pond area.

Description

Technical field

[0001] The invention relates to an EPS lower embankment structure, in particular to an EPS lower embankment structure and a construction method thereof. Background technique

[0002] In recent years, with the rapid development of industry and tourism in the coastal area of ​​my country, more and more low-grade road construction in the coastal area has brought new technical problems to the construction of embankments. There are often a large number of bangtangs in the coastal area. Building roads in the coastal area will inevitably encounter a large number of sections of the bangtang soft soil foundation, and therefore have to face the problem of the treatment of the soft soil roadbed in the bangtang. At present, in the treatment of Bangtang soft soil roadbed, pipe pile method and cement mixing pile method are often used for middle and deep soft soil foundation, and soil replacement method and cushion method are often used for shallow soft soil foundation. In fact...
