Description

Technical Field

[0001] The utility model relates to the technical field of road base maintenance, in particular to a spraying film device for road base maintenance. Background Art

[0002] During highway construction, a film can be formed on the road surface by spraying to achieve corresponding maintenance functions for the road surface. For example, during the construction of cement concrete pavement, the concrete can be maintained by spraying water during the concrete solidification process to avoid subsequent cracking. When the old road surface is converted into an asphalt pavement, the old road surface will also be sprayed with tack coat oil by spraying a film to facilitate the connection between the new surface layer and the original road surface.

[0003] After searching, application number 202320547214.5 discloses a spray membrane device for highway construction, including a base, running wheels and a storage chamber, wherein running wheels are installed under the base, and the movement of the base is controlled by the running wheels, and a storage chamber is fixed above the base for storing materials to be sprayed, and a pump body is arranged above the storage chamber, and a conveying hose is connected to the outside of the pump body, and the lower end of the conveying hose is located in the storage chamber to extract the liquid in the storage chamber, and the outer end of the conveying hose is connected to a guide pipe, and a nozzle is arranged below the guide pipe.

[0004] During use, a spray membrane device for highway construction in this patent application can control the number of installed regulating tubes according to the spray width requirements by using detachable regulating tubes. The spray width can be adjusted by installing different numbers of regulating tubes, which is convenient for adapting to highway construction needs of different widths. However, during such use, since the length of a single regulating tube is fixed, the adjustment of the spray width by the equipment is limited by the length limit of the regulating tube, and the flexibility is poor. It cannot be freely adjusted to the appropriate width according to the construction needs of highways of different widths, which reduces the practicality of the equipment. For this reason, we propose a spray membrane device for pavement base maintenance. Utility Model Content
