[0058] The leveling mechanism is used for leveling in step S2.1 in the embodiment of the application, so that manual leveling is not needed, and leveling work can be quickly completed, thereby improving construction efficiency.

[0059] The leveling mechanism comprises a driving assembly 3, a moving assembly 2, a leveling assembly 4, a cleaning assembly 6, a control assembly 5, a water supply assembly 7 and an intermittent pushing assembly 8.

[0060] Referring to Figure 1 , the moving assembly 2 comprises a cross rod 21, a fixed rod 22, a rotating shaft 23, a moving wheel 24, an auxiliary wheel 25 and a sweeping plate 26, two fixed rods 22 are integrally formed on the bottom walls of the two ends of the cross rod 21 in the length direction in the embodiment of the application, the length of the cross rod 21 is greater than the width of the ash-soil layer 1, and the cross rod 21 is located above the ash-soil layer 1. The leveling assembly 4 is arranged on the cross rod 21.

[0061] Referring to Figure 2 and Figure 3 , the bottom wall of the fixed rod 22 is provided with a receiving groove 221, and the moving wheel 24 is rotatably installed in the receiving groove 211 through the rotating shaft 23. In use, the bottom of the moving wheel 24 is in contact with the ground.

[0062] Referring to Figure 1 , the auxiliary wheel 25 is rotatably installed on the side wall of the fixed rod 22 through a rod body, and the bottom of the auxiliary wheel 25 is flush with the bottom of the moving wheel 24. In the embodiment of the application, two auxiliary wheels 25 are arranged on a single fixed rod 22, and are symmetrically arranged about the fixed rod 22 as a central axis. The auxiliary wheel 25 can assist the moving wheel 24, so that the cross rod 21 is not prone to tilting during leveling of the ash-soil layer 1.

[0063] Referring to Figure 1 , the sweeping plate 26 is fixed to the rod body. In the embodiment of the application, the sweeping plate 26 is in the shape of “L”, and the bottom of the sweeping plate 26 is flush with the auxiliary wheel 25. During movement of the cross rod 21 driven by the moving wheel 24 driven by the driving assembly 3, the sweeping plate 26 can clean the gravel in front of the auxiliary wheel 25, so that the cross rod 21 is relatively stable during the entire movement and is not prone to jolting.

[0064] Referring to Figure 4 and Figure 5The leveling assembly 4 comprises a plurality of leveling rods 41 and connecting ropes 42, and the leveling rods 41 and the connecting ropes 42 are in one-to-one correspondence in the embodiment. One end of the connecting rope 42 is connected to the installation groove 211, and the other end is fixed to the top wall of the leveling rod 41. In the embodiment, the leveling rods 41 are arranged along the length direction of the cross frame rod 21. When it is necessary to level the ash soil layer 1, the connecting ropes 42 are loosened by using the control assembly 5 until the leveling rods 41 are in contact with the top of the ash soil layer 1, and then the cross frame rod 21 is driven to move above the ash soil layer 1 and along the length direction of the ash soil layer 1 by using the driving assembly 3. During the process, if it is observed that some leveling rods 41 are suspended or some leveling rods 41 protrude upward, it is proved that the place is relatively uneven, so the ash soil needs to be added and compacted. In the embodiment, the number of the leveling rods 41 can be increased or decreased according to the required detection accuracy.

[0065] Referring to Figure 3 The driving assembly 3 comprises a rotating rod 31, a first chain wheel 32, a second chain wheel 33, a chain 34 and a first motor 35.

By cooperation of the first chain wheel 32, the second chain wheel 33 and the chain 34, the rotating of the moving wheel 24 can be more stably driven. When it is necessary to level the ash soil layer 1, the first motor 35 is started to drive the rotating rod 31 to rotate, and the rotating of the rotating rod 31 drives the first chain wheel 32, the chain 34, the second chain wheel 33 and the rotating shaft 23 to rotate in sequence. The rotating of the rotating shaft 23 drives the moving wheel 24 to rotate, so that the cross frame rod 21 can move above the ash soil layer 1 and along the length direction of the ash soil layer 1. During the process, the leveling assembly 4 levels the ash soil layer 1, so that manual leveling is not needed, and the leveling work can be quickly completed to improve the construction efficiency.

The driving gear 53 is coaxially sleeved on the driving rod 55, and the driven gear 54 is coaxially sleeved on the first rod 51 and the second rod 52, and the driving gear 53 is engaged with the driven gear 54.

[0069] When it is necessary to level the ash soil layer 1, the second motor 56 is started to drive the driving rod 55 to rotate, the rotation of the driving rod 55 will in turn drive the rotation of the driving gear 53 and the driven gear 54; the rotation of the driven gear 54 will drive the rotation of the first rod 51 and the second rod 52, the rotation of the first rod 51 will loosen the connecting rope 42, until the leveling rod 41 is in contact with the top of the ash soil layer 1, thereby facilitating the leveling of the ash soil layer 1; at the same time, the rotation of the second rod 52 will pull up the cleaning assembly 6, thereby not affecting the leveling of the ash soil layer 1;

[0070] On the contrary, if the connecting rope 42 is to be reeled in, the second motor 56 is driven to reverse.

The wet cloth 63 is fixed to the bottom wall of the fixed plate 62. After the plastic film 14 is laid on the ash soil layer 1, the second motor 56 is started to loosen the lifting rope 61 until the wet cloth 63 is attached to the plastic film 14, and then the cross rod 21 is controlled to return along the original route. During the returning process, the wet cloth 63 can clean the top of the plastic film 14 to ensure that the top of the plastic film 14 is relatively clean, so that the strength of the concrete during solidification is not easily affected by impurities; and the wet cloth can moisten the plastic film 14, so that the water in the concrete is not easily absorbed, thereby improving the compactness of the concrete after solidification, i.e. improving the strength of the concrete.

The top wall of the horizontal frame rod 21 is provided with a displacement slot 214 in the width direction, and the displacement slot 214 is in communication with the containing cavity 213. One end of the pushing plate 74 is fixed to the top wall of the sealing plate 73, and the other end extends to the top of the horizontal frame rod 21 through the displacement slot 214. In the process of moving the horizontal frame rod 21, the intermittent pushing assembly 8 can push the pushing plate 74.

[0077] Referring to Figure 7 , one end of limiting rod 84 away from limiting spring 80 is provided with guide surface 841, guide surface 841 is arranged obliquely, and the one end of guide surface 841 close to limiting spring 80 is lower than the opening of limiting hole 8211. In the process of leveling, when third rod 81 rotates, even if limiting rod 84 is inserted into limiting hole 8211, limiting rod 84 can be pressed back into installation hole 851 again through guide surface 841, so that third rod 81 idles and does not drive fourth rod 82 to rotate; in the process of cleaning wet cloth 63, third rod 81 will be reversed, at this time, after limiting rod 84 is inserted into limiting hole 8211, it cannot be pressed back into installation hole 851, so that third rod 81 can drive fourth rod 82 to rotate.

[0078] Referring to Figure 6The transmission rod 86 is rotatably installed on the horizontal frame rod 21 and vertically arranged, one end of the transmission rod 86 penetrates into the installation groove 211 and is coaxially fixed with the rotating gear 88, the other end is located at the top of the horizontal frame rod 21 and is fixed with the cam 89, the transmission gear 87 is coaxially sleeved on the fourth rod 82, and the transmission gear 87 is engaged with the rotating gear 88. When the fourth rod 82 rotates, the transmission gear 87, the rotating gear 88, the transmission rod 86 and the cam 89 are sequentially driven to rotate, the rotation of the cam 89 constantly pushes the push plate 74, so that the push plate 74 drives the sealing plate 73 to reciprocatingly slide, so as to intermittently open the communication hole 212.

[0079] The working principle of the cast-in-place concrete modular pavement construction method of the application in use is as follows: when the soil layer 1 needs to be leveled, the second motor 56 is started to drive the driving rod 55 to rotate, the rotation of the driving rod 55 will sequentially drive the rotation of the driving gear 53 and the driven gear 54; the rotation of the driven gear 54 will drive the first rod 51 and the second rod 52 to rotate, the rotation of the first rod 51 will loosen the connecting rope 42 until the leveling rod 41 is in contact with the top of the soil layer 1, thereby facilitating the leveling of the soil layer 1.

[0080] The above are preferred embodiments of the application, but not limit the protection scope of the application, therefore: all equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
