Description

Technical Field

[0001] The utility model relates to the technical field of subgrade and pavement, in particular to a splicing structure for new and old subgrade and pavement of highway engineering. Background Technique

[0002] With the rapid development of China's social economy, the proportion of private cars owned by people is increasing continuously. This has also led to traffic congestion on some roads due to their small width. In addition, the cost of building a new road is high, so generally the old road will be spliced and widened.

[0003] In the patented document with the authorized publication number of CN214783018U, a splicing structure for new and old subgrade and pavement is disclosed, which includes a new subgrade, a new pavement, an old subgrade and an old pavement. The old pavement is laid on the old subgrade to form an old road, and the new pavement is laid on the new subgrade to form a new road. Multi-level first steps are arranged on the splicing surfaces of the old subgrade and the old pavement, and multi-level second steps spliced with the first steps are arranged on the splicing surfaces of the new subgrade and the new pavement. A first fixing groove is opened on the top surface of the first step. This application has the effect of reducing the situation of cracks at the splicing due to the settlement difference between the new road and the old road.

[0004] When the above device is implemented, when the new soil pile and the old soil pile are connected, a strengthening block is used for connection. The setting of multiple groups of strengthening blocks is not convenient for the staff to install them. The splicing part of the subgrade is relatively narrow, and then it increases the working difficulty of the staff when strengthening horizontally with the strengthening blocks. Content of the Utility Model

The setting of multiple groups of strengthening blocks is not convenient for the staff to install them. The splicing part of the subgrade is relatively narrow, and then it increases the working difficulty of the staff when strengthening horizontally with the strengthening blocks.

[0006] The embodiment of the present application provides a splicing structure for new and old subgrade and pavement of highway engineering, which includes a subgrade main body and multiple groups of main filling blocks.

Multiple groups of locking rods are slidably penetrated through the main filling block and the auxiliary filling block. A first T-shaped block is slidably inserted into the inner wall of the multiple groups of main filling blocks.

[0007] By adopting the above technical solution, the multi-group main filling blocks and auxiliary filling blocks can play a role in splicing at the joint. The locking rod is inserted vertically, and holes can be dug in the main filling block and the auxiliary filling block in advance, which is convenient for the staff to lock the main filling block and the auxiliary filling block, reducing the workload of the staff.

[0008] Optionally, a covering layer is laid on the upper end of the auxiliary filling block.

[0014] Optionally, T-shaped grooves are formed on the upper side surfaces of the multiple groups of main filling blocks, and the first T-shaped blocks slide through the T-shaped grooves.

[0015] By adopting the above technical solution, the T-shaped grooves can allow the first T-shaped blocks to slide and be clamped inside another group of main filling blocks.

[0025] Please refer to Figures 1-3 , the present invention provides a technical solution: a splicing structure of a new and old roadbed and road surface in a highway project, including a roadbed main body 1 and multiple groups of main filling blocks 2. The inner wall of the roadbed main body 1 is slidably connected with multiple groups of main filling blocks 2. The upper end of the main filling block is slidably connected with an auxiliary filling block 5. A clamping mechanism is arranged between the main filling block 2 and the auxiliary filling block 5 and the roadbed main body 1. Multiple groups of locking rods 9 are slidably inserted through the main filling block 2 and the auxiliary filling block 5. Multiple groups of first T-shaped blocks 3 are slidably inserted into the inner walls of the multiple groups of main filling blocks 2. The clamping mechanism includes multiple groups of first sliders 4, and the multiple groups of first sliders 4 are respectively fixedly connected with the main filling blocks 2. The first sliders 4 slide into the inside of the roadbed main body 1.

[0026] In this technical solution, through the setting of multiple groups of main filling blocks 2 and auxiliary filling blocks 5, the joint can be spliced. The locking rods 9 are inserted vertically, and holes can be dug in the main filling blocks 2 and the auxiliary filling blocks 5 in advance, which is convenient for the staff to lock the main filling blocks 2 and the auxiliary filling blocks 5, reducing the workload of the staff.

[0027] In addition, the setting of the first slider 4 can play a role in clamping the roadbed main body 1 and the main filling block 2.

[0028] In some technical solutions, such as Figure 1 and Figure 3 shown, the two sides of the auxiliary filling block 5 are respectively fixedly connected with second sliders 6. The second sliders 6 slide into the interior of the roadbed main body 1. The setting of the second sliders 6 can play a role in clamping the auxiliary filling block 5 and the roadbed main body 1. T-shaped grooves are formed on the upper side surfaces of multiple groups of main filling blocks 2. The first T-shaped blocks 3 slide through the T-shaped grooves. The setting of the T-shaped grooves allows the first T-shaped blocks 3 to slide and be clamped into the interior of another group of main filling blocks 2. The lower end of the auxiliary filling block 5 is fixedly connected with a second T-shaped block 7. The second T-shaped block 7 slides into the T-shaped groove. The second T-shaped block 7 can slide into the T-shaped groove, so that the auxiliary filling layer can be slidably clamped to the main filling layer. The auxiliary filling block 5 has a small size, which is convenient for coping with the depth change of the roadbed main body 1.

[0029] In some technical solutions, such as Figure 1 and Figure 2 shown, a covering layer 8 is laid on the upper end of the auxiliary filling block 5. The setting of the covering layer 8 can play a role in covering the auxiliary filling block 5 and can play a role in shielding the locking rod 9.

[0030] During use, first, the setting of multiple groups of main filling blocks 2 and auxiliary filling blocks 5 can play a role in splicing the connection part. The locking rod 9 is inserted vertically, and holes can be dug in the main filling blocks 2 and auxiliary filling blocks 5 in advance, which is convenient for the staff to lock the main filling blocks 2 and auxiliary filling blocks 5, reducing the workload of the staff. The setting of the covering layer 8 can play a role in covering the auxiliary filling block 5 and can play a role in shielding the locking rod 9. Then, when the first T-shaped blocks 3 and the second T-shaped blocks 7 slide into the interior of the T-shaped grooves, they can respectively play a role in slidably clamping multiple groups of main filling blocks 2 and auxiliary filling blocks 5. The first slider 4 and the second slider 6 can play a role in slidably clamping the main filling block 2, the auxiliary filling block 5 and the roadbed main body 1.
