[0002] Precast road slabs are a kind of road building materials widely used in construction, especially in scenarios where temporary roads or rapid road laying are required.

[0003] Existing precast road slabs can be reused. After the precast road slabs are used, a certain amount of soil may accumulate on the surface of the precast road slabs. Therefore, it is necessary for staff to clean them. However, some stubbornly accumulated soil requires staff to spend time to remove, and the existing precast road slabs are not convenient for staff to quickly process the soil.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

Inside the jacks, a precast road panel with grooves on its upper surface is slidably inserted. On the upper surface of the jacks, convex blocks are provided. On the lower surface of the jacks, winding grooves are opened. Inside the winding grooves, an automatic return component is arranged. The automatic return component includes a winding belt. The automatic return component is in mutual cooperation and linkage with the precast road panel. At both ends of the precast road support plates, a multi-plate splicing component that can cooperate with each other is arranged. The multi-plate splicing component includes a docking block and a docking plate.

[0007] Further, in order to facilitate providing an anti-slip effect for the precast road panel through the grooves, the grooves are linearly and evenly arranged on the upper surface of the precast road panel. The convex blocks are linearly and evenly fixedly installed at the inner top wall position of the jacks in the precast road support plates. The convex blocks and the grooves are tightly inserted into each other.

[0008] Further, in order to limit the precast road panel, sliding T-shaped grooves are symmetrically opened on the lower surfaces at both ends of the jacks. On the lower surface of the precast road panel, sliding T-shaped blocks are symmetrically fixedly installed. The sliding T-shaped blocks and the sliding T-shaped grooves are slidably clamped with each other.

[0009] Further, in order to provide spring elastic force to the winding drum through the winding spring, the automatic return component further includes a winding drum, which is rotatably installed in the winding groove. A winding spring is arranged inside the winding drum. One end of the winding spring is fixedly connected to the inner wall of one end of the winding groove, and the other end of the winding spring is fixedly connected to the inner wall of one end of the winding drum.

[0011] Further, in order to provide support and buffer force to the precast road panel through the spring telescopic rod, and at the same time, the tight insertion of the T-shaped insert block and the T-shaped slot facilitates the fixation and limitation of the mud collecting box. Symmetrically and evenly fixed spring telescopic rods are installed on the upper surface of the precast road bottom plate. The upper end of the spring telescopic rod is in contact with the lower surface of the precast road panel. A T-shaped slot is opened on one side of the lower end of the precast road support plate. A mud collecting box is arranged on one side of the precast road support plate. A T-shaped insert block is fixedly installed on one side of the mud collecting box, and the T-shaped insert block is tightly inserted into the T-shaped slot.

[0012] Further, in order to provide spring elastic force to the T-shaped insertion rod through the docking spring, the docking block in the multi-board splicing component is fixedly installed at one end of the precast road support plate, the docking plate is fixedly installed at the other end of the precast road support plate. A T-shaped circular groove is opened in the docking block, and a T-shaped insertion rod is inserted into the T-shaped circular groove. A docking spring is fixedly installed inside the upper end of the T-shaped circular groove, and one end of the docking spring is fixedly connected to the T-shaped insertion rod.

[0013] Further, in order to be able to dock with the T-shaped insertion rod, a docking hole matching the T-shaped insertion rod is opened on the upper surface of the docking plate.

[0014] The beneficial effects of the present utility model are as follows: 1. The device can facilitate the cleaning of the accumulated soil on the precast road panel by the cooperation of the convex block, the groove, the automatic return component and the precast road panel. At the same time, the mud collecting box can facilitate the staff to collect the soil and dump it centrally.

[0026] As Figure 5 and Figure 6 shown, the grooves 4 are linearly and uniformly arranged on the upper surface of the precast road panel 5, and the bumps 6 are linearly and uniformly fixedly installed at the inner top wall position of the inner socket 2 of the precast road support plate 3. The bumps 6 are tightly inserted into the grooves 4. Sliding T-shaped grooves are symmetrically formed on the lower surfaces at both ends of the socket 2. Sliding T-shaped blocks 10 are symmetrically and fixedly installed on the lower surface of the precast road panel 5. The sliding T-shaped blocks 10 are slidably clamped with the sliding T-shaped grooves. The automatic return component 8 further includes a winding drum 802 which is rotatably installed in the winding groove 7. A winding spring 803 is arranged in the winding drum 802. One end of the winding spring 803 is fixedly connected to the inner wall at one end of the winding groove 7, and the other end of the winding spring 803 is fixedly connected to the inner wall at one end of the winding drum 802. The winding belt 801 is wound and laid on the outer circumferential surface of the winding drum 802. One end of the winding belt 801 is fixedly connected to the lower surface of the precast road panel 5. Spring telescopic rods 11 are symmetrically and uniformly fixedly installed on the upper surface of the precast road bottom plate 1.

A docking hole matching the T-shaped insertion rod 903 is formed in the upper surface of the docking plate 902. When the staff docks multiple precast road support plates 3, the staff pulls the T-shaped insertion rod 903, and then inserts the docking plate 902 on another precast road support plate 3 into the docking block 901. At this time, the staff releases the T-shaped insertion rod 903 to achieve the docking of the T-shaped insertion rod 903 and the docking hole, thereby realizing the docking of multiple precast road support plates 3.
