Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a convenient highway and bridge paving construction device. Background Technology

[0002] Road and bridge paving refers to the protective layer laid on the bridge deck. Its main function is to prevent the wheels or tracks from directly abrading the bridge deck, distribute the wheel load, and provide a flat and non-slip driving surface for vehicles. During paving, the loose concrete and floating slurry on the bridge deck, the exposed sponge strips at the base of the guardrail, and the loose concrete are first removed. Then, an air compressor is used to assist manual water flushing to thoroughly clean the bridge deck, ensuring that there is no dust, floating slurry, or loose concrete.

[0003] When cleaning with water, the air compressor needs to be mounted on a mobile cart for easy movement. However, in the current technology, workers usually place the cart with the air compressor behind them and the nozzle connected to the air compressor in front of them while cleaning, making it difficult to control the cart behind them and the water pipes dragged on the ground, thus increasing the difficulty of use.
