[0027] Among them, the splicing seat 2 is arranged on a wide side wall of the pavement substrate, and the splicing joint 11 is arranged on the other wide side wall of the pavement substrate, so that two adjacent pavement substrates can be closely spliced ​​in sequence during paving, ensuring stable and reliable pavement paving, avoiding uneven splicing and large splicing spacing, which affects the appearance and the use effect; at the same time, a reinforcing rod 14 is arranged at the bottom of the pavement substrate to ensure that the pavement substrate is stable and not shifted after paving, further improving the use experience of the pavement, and can also meet the paving needs of temporary pavements.

[0028] Specifically, the interior of the splicing seat 2 is provided with a plug-in slot 5, and the bottom end of the plug-in slot 5 is fixedly connected to a positioning rod 6; the bottom end of the splicing joint 11 is fixedly connected to a plug-in rod 12, and the interior of the plug-in rod 12 is provided with a positioning slot 13, the opening of the plug-in slot 5 faces upward, and there are multiple positioning rods 6, and the multiple positioning rods 6 are arranged at equal intervals along the length direction of the plug-in slot 5. The plug-in rod 12 matches the plug-in slot 5, and the number of positioning slots 13 is also multiple, and the multiple positioning slots 13 are arranged at equal intervals along the length direction of the plug-in rod 12, so that the number and position of the positioning rods 6 and the positioning slots 13 correspond one to one, which facilitates the splicing of two adjacent pavement substrates and the tightness of the splicing during paving, and improves the stability and reliability of the splicing.

[0029] In order to further improve the splicing reliability, a first splicing block 15 and a second splicing block 17 are respectively arranged on the front and rear sides of the pavement substrate; specifically, the first splicing block 15 is arranged on one long side wall of the pavement substrate, and the second splicing block 17 is arranged on the other long side wall of the pavement substrate, and the first splicing block 15 and the second splicing block 17 are located at the same horizontal height; the number of first splicing blocks 15 and the number of second splicing blocks 17 are both multiple, and the multiple first splicing blocks 15 and the multiple second splicing blocks 17 are all arranged at equal intervals in the horizontal direction, and the first splicing blocks 15 and the second splicing blocks 17 are staggered.

[0030] During paving, the splicing seat 2 and the splicing joint 11 are used to realize the splicing between the front and rear pavement substrates, and the first splicing block 15 and the second splicing block 17 are used to realize the splicing between the left and right pavement substrates. The splicing is tight and reliable, ensuring the paving effect.

[0031] Further explanation: the pavement substrate includes a concrete base 3, a reinforcement layer 4, an asphalt concrete layer 9, a permeable paving layer 8 and a pavement surface layer 7 laid in sequence from bottom to top, a reinforcing rod 14 is arranged at the bottom of the concrete base 3, and a fixing plate 21 is arranged between the reinforcing rod 14 and the concrete base 3.

[0032] A plurality of supporting steel bars 10 connected in sequence are arranged inside the reinforcing layer 4. The supporting steel bars 10 are of an "X"-shaped structure. A supporting block 19 is arranged inside the supporting steel bars 10. Connecting steel bars 22 are arranged on the outside of the supporting steel bars 10. The connecting steel bars 22 are connected between two adjacent supporting steel bars 10.

[0033] To further illustrate, there are multiple reinforcement rods 14 , which are arranged in an array at the bottom of the fixing plate 21 , and barbs 20 are provided on the reinforcement rods 14 .

[0034] A support column 1 is provided on the outside of the fixing plate 21 , and the support column 1 is located on the outside of the reinforcing rod 14 . The number of the support columns 1 can be selected to be four, and the four support columns 1 are located at the top corners of the concrete base 3 , and the support columns 1 are connected to the bottom of the concrete base 3 .

[0035] During installation, the bottom of the concrete base 3 is laid on the road base, and the reinforcement rods 14 at the bottom of the concrete base 3 and the four groups of support columns 1 can be inserted into the interior of the base. The reinforcement rods 14 can increase the area connected to the base, and the barbs 20 on the outside of the reinforcement rods 14 can improve the firmness of the grip.

[0036] The splicing seat 2 is arranged on the outside of the concrete base 3 , and the splicing joint 11 is arranged on the outside of the pavement surface layer 7 .

[0037] Further explanation, in order to facilitate the lifting of the pavement base, a hanging plate 16 is selected to be set on the outside of the asphalt concrete layer 9, and the hanging plate 16 is respectively located below the first splicing block 15 and the second splicing block 17; the number of hanging plates 16 can be selected to be two, and both hanging plates 16 pass through the asphalt concrete layer 9 along the width direction of the pavement base, and hanging holes 18 are opened at both ends of the hanging plate 16.

[0038] When the pavement substrate needs to be transferred and transported, it can be hoisted using the hoisting holes 18 on the hoisting plate 16. After the hoisting is completed, the hoisting plate 16 can be removed.

[0039] Working principle:

[0040] When the present invention is used, the base layer needs to be laid first, and then the hanging plate 16 is inserted into the asphalt concrete layer 9, and the road surface substrate is hoisted to the position to be laid with the help of the hanging holes 18, and then the hanging plate 16 is removed.

[0041] Then the pavement base is laid in sequence, so that the left and right pavement bases are spliced ​​with the help of adjacent splicing grooves 5 and splicing rods 12, and the front and rear pavement bases are spliced ​​with the help of adjacent first splicing blocks 15 and second splicing blocks 17 to ensure the tight laying of the temporary pavement. At the same time, the support column 1 and the reinforcement rod 14 are inserted into the interior of the base layer. The reinforcement rod 14 can increase the area connected to the base layer, and the barbs 20 on the outside of the reinforcement rod 14 can improve the firmness of the grip.

[0042] The supporting steel bars 10 and the supporting blocks 19 inside the reinforcing layer 4 enhance the supporting stability. This structure realizes the functions of facilitating movement and enhancing the supporting strength.
