Description

Technical Field

[0001] The utility model relates to the field of roads, in particular to a road water-stable base paving and leveling device. Background Art

[0002] Water-stable layer is the abbreviation of cement-stabilized crushed stone layer, that is, graded crushed stone is consolidated with cement, and the mixture is compacted and cured. The mix ratio of water-stable should be tested in the laboratory in advance to determine the cement dosage and the ratio of coarse and fine aggregates, and the maximum dry density. A large amount can be mixed by a water-stable mixing station. Cement-stabilized crushed stone uses graded crushed stone as aggregate, and a certain amount of cementitious materials and sufficient mortar volume are used to fill the gaps in the aggregates. It is spread and compacted according to the interlocking principle. Its compaction degree is close to the density. The strength mainly depends on the interlocking principle between the crushed stones. At the same time, there is enough mortar volume to fill the gaps in the aggregates. A Chinese patent discloses a road water-stable base paving and leveling device (authorization announcement number CN 219080025 U), this patented technology can cooperate with the connecting shaft when in use, so that the movable seat at the bottom of the hollow tube can be rotatably connected to the connecting seat through the connecting shaft, and then a pull adjustment component is symmetrically arranged on the outside of the hollow tube, that is, when the connecting hole opened at the symmetrical position of the road is connected to the connecting seat and tilts, the pull adjustment component can be used to cooperate with the level ruler to make the hollow tube and the movable seat vertical to the road, so that there is no need to re-drill holes, so as to improve the overall work efficiency.
