Abstract

The invention discloses a foam light soil roadbed which comprises a pouring frame and a cross-shaped plate, wherein the pouring frame comprises a bottom plate and four side plates, and the four side plates are perpendicular to the bottom plate and are respectively connected with the four side edges of the bottom plate; the cross-shaped plate comprises a horizontal part and a vertical part, the vertical part is clamped between the two opposite side plates and divides the interior of the pouring frame into a first containing space and a second containing space, the horizontal part is perpendicularly connected to the surface of the vertical part; and foam light soil is poured in the first containing space and the second containing space respectively, and the foam light soil has different densities. According to the invention, the roadbed cost is reduced, and the possibility of settlement at the soft foundation section is reduced.

Description

technical field [0001] The invention relates to the related field of roadbed. More specifically, the present invention relates to a foam lightweight soil roadbed. Background technique [0002] For the safety and smooth operation of vehicles, the subgrade structure should have sufficient strength and stability. In order to meet these requirements, it is usually necessary to use a large number of high-standard fillers, which has high costs and is prone to settlement in soft foundation sections. The foam lightweight soil is characterized by the formation of closed foam pores inside the concrete, which makes the concrete lightweight, and its use in roadbeds may overcome the above problems. Contents of the invention [0003] An object of the present invention is to provide a foam lightweight soil roadbed, which reduces the cost of the roadbed and reduces the possibility of settlement in the soft foundation section. [0004] In order to achieve these objects and other advantag...
