Description

Technical Field

[0001] The utility model relates to the technical field of high fill subgrade construction, in particular to a material transporting device for crushed stone soil high fill subgrade construction. Background Technique

[0002] A high fill subgrade refers to an embankment with a filling height greater than 18 meters (for soil) or 20 meters (for rock), which belongs to the category of high fill subgrades. This kind of subgrade is usually used in paddy fields or areas with perennial water accumulation. By using fine-grained materials for filling, the embankment height is greater than 6 meters. In other areas, when the height of the soil or rock fill embankment exceeds a certain standard, it is also called a high fill subgrade.

[0003] Due to its unique physical properties, such as good water permeability, fast drainage consolidation speed during compression, high density, and large shear strength, crushed stone soil is very suitable as a filling material for high fill subgrades.

[0004] In the prior art, crushed stone soil is generally transported by a muck truck, and the crushed stone soil is transferred through the carriage. In order to reduce the impact on the environment in the prior art, a foldable tarpaulin is generally installed on the upper part of the carriage. However, the flexible tarpaulin freezes and hardens when encountering water in winter, which may cause difficulties in stretching the tarpaulin.

[0005] Therefore, we propose a material transporting device for crushed stone soil high fill subgrade construction. Content of the Utility Model
