Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a road and bridge marking device for construction engineering. Background Art

[0002] In the process of construction engineering, it is necessary to lay steel mesh on the road surface. The steel bars need to be laid at a certain interval. Therefore, it is necessary to mark the distance on the road surface before laying the steel bars. When installing guardrails in the middle of the road, it is also necessary to mark dots at equal intervals. Before the existing dotting device is used, the dots will disappear quickly due to the dust on the road surface. In the actual construction process, multiple dots need to be marked in a horizontal position. Therefore, a larger horizontal position needs to be cleaned. Manual cleaning will increase the workload of personnel. For this reason, we propose a road and bridge dotting device for construction engineering. Utility Model Content
