Description

Technical Field

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

[0002] Water-stabilized leveling refers to the use of cement mortar, concrete or other materials to level and level the ground or floor slab to ensure that the surface level and flatness meet the design requirements. This work is usually carried out during construction or decoration to provide a uniform and flat foundation for the subsequent laying of floors, tiles and other surfaces. The steps of water-stabilized leveling usually include cleaning the ground, checking and repairing cracks and uneven parts of the ground, preparing appropriate cement mortar or concrete, spreading it evenly on the ground that needs to be leveled, and then using leveling tools to level it. After the leveling is completed, the leveling layer needs to be properly maintained to ensure that the mortar or concrete is fully solidified and hardened.

[0003] Water-stabilized leveling is very important for the subsequent ground paving and decoration. It can improve the flatness and aesthetics of the ground, and also help the service life of the ground materials. In the actual operation process, it is necessary to strictly follow the design requirements and construction specifications to ensure that the leveling effect meets the requirements. During the construction of road water-stabilized leveling, a water-stabilized paving leveling device is required for auxiliary leveling.
