[0002] Municipal engineering refers to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (villages), and provide paid or free public products and services to residents based on government responsibilities and obligations. Pavement construction includes base layer paving, penetration layer, sealing layer, paving of lower layer, adhesive layer, paving of upper layer, etc.

[0003] During the pavement construction process, asphalt mixture needs to be laid on the road surface. When the mudflattener passes through the inspection well, some asphalt mixture remains on the top of the cover. The staff needs to clean it quickly to absorb the excess asphalt mixture and prevent the asphalt mixture from adhering to the well cover. This process is time-consuming and labor-intensive.

[0017] The present invention provides a road construction device for municipal engineering with an adjustment function. It has the following beneficial effects:

[0018] (1) The road construction device for municipal engineering with an adjustment function uses a cleaning device to press down the manhole cover with a sponge block and a sponge cone. The rotating sponge block and sponge cone absorb the asphalt mixture on the manhole cover. The asphalt mixture is squeezed out of the sponge block and sponge cone by squeezing, thereby maintaining the liquid absorption capacity of the sponge block and sponge cone and preventing them from over-hardening.

[0019] (2) The road construction device for municipal engineering with an adjustment function adjusts the height of the moving rod through the guide mechanism and the loosening and tightening of the threaded rod, so that the ring is close to the asphalt layer. The inner diameter of the ring is larger than the diameter of the inspection manhole cover, which makes it easy to observe the relative position of the ring and the inspection manhole cover.

[0020] (3) The road construction device for municipal engineering with an adjustment function, through the liquid discharge mechanism, when cleaning, the liquid storage box and the filter pressure plate move outward, which will not hinder the sponge block and sponge cone from moving downward. When removing the liquid, the liquid storage box and the filter pressure plate move inward. As the bottom pressure plate, the sponge block and sponge cone press down the filter pressure plate. The sponge block and sponge cone are continuously compressed, and the asphalt mixture inside is continuously squeezed out and flows into the liquid storage box through the filter hole. Under the action of the sensor, the sponge block and sponge cone can move between the filter pressure plate and the top box. Through the squeezing action, the liquid absorption capacity and a certain softness of the sponge block and sponge cone are maintained, and the next inspection well cover can be cleaned.

[0021] (4) The road construction device for municipal engineering with an adjustment function, through the cleaning mechanism, the sponge cones are evenly distributed on the bottom surface of the entire sponge block, the sponge cones move down and contact the surface of the inspection well cover, the sponge cones are small, and the tip of the sponge cones can penetrate into the groove on the inspection well cover, and then the bidirectional motor is started, and the shaft rotates with the second fixed plate, the pneumatic hydraulic pump, the connecting plate, the slide rod, the sponge block, and the sponge cone in turn. The sponge block and the sponge cone can quickly absorb the asphalt mixture, and the liquid absorption capacity of the sponge block is much greater than the liquid absorption capacity of the sponge cone. The rotating sponge cone quickly absorbs the asphalt mixture on the surface of the inspection well cover and in the groove, and can quickly clean the inspection well cover. As the asphalt absorbed by the sponge cone continues to increase, part of the asphalt mixture in the sponge cone moves up to the sponge block. BRIEF DESCRIPTION OF THE DRAWINGS
