Description

Technical Field

[0001] The utility model relates to the technical field of concrete leveling, in particular to a concrete leveling device used in building construction. Background Art

[0002] Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc. The place where the construction work is done is called "construction site" or "construction site", also called construction site.
