Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering road surface construction, in particular to a circle drawing device based on municipal engineering road surface construction. Background Art

[0002] Municipal engineering pavement construction is an important part of urban infrastructure construction. It is of key significance for ensuring smooth urban traffic and improving the quality of life of residents. During the construction of municipal engineering pavement, a circle drawing device is needed to mark the road. The circle drawing device can accurately draw circular patterns of different radii on the road surface to ensure that the shape of the road marking is regular and the size is accurate.

[0003] The applicant believes that:

[0004] When a circle-drawing device is used to draw circles on the pavement of municipal engineering projects, the diameters of the circular markings required on the pavement are often different in different municipal engineering scenarios. If the circle-drawing device cannot adjust the diameter, the construction party will have to prepare multiple circle-drawing devices with different diameter specifications, which greatly increases the equipment cost and storage space requirements. Moreover, during the construction process, the circle-drawing device needs to be frequently replaced according to different needs, which reduces construction efficiency and affects the progress of the project, and thus requires improvement.
