Description

Technical Field

[0001] The present application belongs to the technical field of concrete anti-cracking maintenance, and specifically relates to a concrete anti-cracking device for concrete pavement maintenance. Background Art

[0002] Concrete pavement maintenance refers to a series of protective measures and operations carried out after the construction of the concrete pavement is completed to ensure its performance and service life. The main purpose of concrete pavement maintenance is to maintain the integrity, stability and durability of the pavement, and to prevent cracks, damage, wear and other problems caused by factors such as the natural environment, vehicle pressure, and chemical corrosion. During the maintenance process, the surface of the concrete pavement is often watered. Proper watering can maintain the moisture of the pavement, help slow down the drying of the pavement and the evaporation of water, thereby reducing the stress caused by shrinkage and reducing the possibility of cracking.

[0003] For example, the utility model patent with announcement number CN218813716U discloses an anti-cracking maintenance device for port concrete, comprising a support plate, the upper surface of the support plate is fixedly connected to a support frame, a water pump is fixedly installed on the upper surface of the support frame, a sprinkler mechanism is arranged below the water pump, lifting mechanisms are arranged on both sides of the support plate, the movable end of the lifting mechanism is fixedly connected to the sprinkler mechanism, and the lower surface of the support plate is fixedly connected to a driving mechanism. In this anti-cracking maintenance device for port concrete, the water pump is started to pump water out of the water tank, and the water pump then transports the water to a hose through a water pipe connected at one end, the hose guides the water downward into a conduit, and the conduit disperses the water to a plurality of sprinkler nozzles. According to the height of the road surface, the lifting mechanism is started to adjust the bottom sprinkler mechanism up and down, and at the same time, a wind shield box fixedly connected to the outer surface of the sprinkler nozzle can effectively prevent water mist from flying everywhere during the sprinkling process.

[0004] However, in actual use, it was found that the windshield box of the device prevents the water mist from flying everywhere during the watering process of the sprinkler head, making the ground watering more uniform, and drives the sprinkler mechanism to adjust the height through the adjustment mechanism to meet the needs of different ground environments;

[0005] However, the bottom of the windshield box of the device is close to the ground. When encountering ground protrusions, the operator needs to pay attention to the road conditions at all times and manually start the adjustment mechanism to make adjustments. Such frequent adjustment operations not only affect the work efficiency and the uniformity of watering, but may also bring inconvenience to the operator. Therefore, a concrete anti-cracking device for concrete pavement maintenance is provided. Utility Model Content
