When the emergency supporting mechanism of the concrete paver works, concrete needs to be firstly inverted on a roadbed, then the spiral stirrer flattens the concrete, and the flattening roller flattens the concrete, so that the concrete is paved.

In view of the above-mentioned related technologies, the inventor thinks that after concrete is poured on a roadbed, the thickness of the concrete at different positions of the roadbed is different, and when the emergency support mechanism of the concrete paver travels to a position where the thickness of the concrete is thinner, the spiral stirrer cannot flatten the concrete, so that the defect that the pavement paved by the paver is uneven exists.

Under the effect of the first blocking piece 413 and the second blocking piece 414, the influence of concrete gravity on the door body 420 can be reduced, the accuracy of the concrete on the roadbed is supplemented by the material supplementing pipe 410, and the condition that the pipe orifice at the bottom of the material supplementing pipe 410 is normally open is reduced.

And a flattening sheet 415 is arranged on one side of the material supplementing pipe 410, which is opposite to the advancing direction of the machine frame 100, one end of the flattening sheet 415 is hinged with the material supplementing pipe 410, and the other end of the flattening sheet 415 is arranged in a bending way along the direction close to the second compacting roller 320. When the flattening sheet 415 is only subjected to self gravity, the height of the end, relative to the horizontal plane, of the flattening sheet 415 far away from the material supplementing pipe 410 is lower than the height of the bottom of the second compacting roller 320 relative to the horizontal plane. When the door body 420 is used for filling concrete on the roadbed, the door body 420 and the concrete on the roadbed slide relatively, so that scratches are left on the concrete surface on the roadbed, the flattening sheet 415 is in contact with the concrete on the roadbed at the moment, and the scratches on the concrete surface on the roadbed are flattened, and further the influence of the scratches on the concrete surface on the roadbed on the construction quality of the concrete pavement is reduced.

The implementation principle of the concrete pavement paver of the embodiment of the application is as follows: when the paver is used, concrete is poured into the material supplement pipe 410, and then the material supplement pipe 410 is filled with the concrete. Then, the driving motor 121 is started to push the machine frame 100, the rolling wheels 110 roll relative to the roadbed, and the machine frame 100 advances along the concrete laying direction. During the advance of the frame 100, the driving motor 121 drives the first leveling roller 210 and the second leveling roller 220 to rotate. The first leveling roller 210 drives the first section 212 and the second section 213 to rotate, the second leveling roller 220 drives the third section 222 and the fourth section 223 to rotate, and the first section 212, the second section 213, the third section 222 and the fourth section 223 pave concrete on a roadbed so that the concrete is uniformly paved on the roadbed.

When the frame 100 advances, one end of the door body 420, which is far away from the rotating shaft 412, contacts with concrete on a roadbed, and the first compaction roller 310 and the second compaction roller 320 compact the paved concrete, so that the occurrence of a cavity in the concrete on the roadbed is reduced. When the frame 100 walks to the uneven position of concrete hole on the road bed, the door body 420 continues to contradict with concrete on the road bed, the door body 420 and feed supplement pipe 410 take place relative rotation, the bottom mouth of pipe of feed supplement pipe 410 is opened to the door body 420, concrete in the feed supplement pipe 410 flows out through the mouth of pipe of feed supplement pipe 410 bottom and contacts with concrete on the road bed, and then reaches the effect of filling up for concrete on the road bed, reduces the uneven condition of concrete hole on the road bed and takes place.

The embodiment of the application also discloses a concrete paving method.

A concrete paving method comprising the steps of: and S1, compacting the roadbed, paving the roadbed, compacting the roadbed after the roadbed is paved, and increasing the stress strength of the roadbed. And S2, conveying the concrete to a construction site by using the concrete truck when the concrete is put upside down on the roadbed, and adopting the concrete truck to unload the concrete while walking, thereby reducing the occurrence of the condition that the concrete needs to be pre-paved by workers again.

And S3, paving the concrete, and paving the concrete by using a paver so that the paver advances along the paving direction of the concrete on the roadbed. And when the paver advances, controlling the speed of the paver to enable the speed of the paver to be lower than 5 km/h. The paving uniformity of the concrete on the roadbed is improved, the occurrence of uneven pits after the concrete on the roadbed is formed is reduced, and the construction quality of the concrete pavement is improved.

And S4, sawing the concrete pavement, and after the concrete on the roadbed is solidified and molded, sawing the molded concrete, wherein the sawing direction of the sawing is vertical to the paving direction of the concrete on the roadbed. When the saw seams are formed, the equal distance between every two adjacent saw seams is kept as much as possible.

The implementation principle of the concrete paving method in the embodiment of the application is as follows: when concrete is paved, the roadbed needs to be constructed and tamped. And (4) after the roadbed is tamped, transporting the concrete to a construction site, and inverting the concrete on the roadbed. And then the paver enters the field, and the paver paves the concrete inverted on the roadbed, so that the paving uniformity of the concrete on the roadbed is improved, and the occurrence of uneven pits after the concrete on the roadbed is formed is reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
