Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of grouting, especially to a highway pavement base grouting structure. BACKGROUND

[0002] Grouting technology is a common civil engineering technique that uses injected solidifying materials to reinforce pavement structures. When cracks, settlement, or other issues arise in pavement structures, specific solidifying materials (usually composed of cement, mortar, etc.) are injected to reinforce the pavement, increasing its load-bearing capacity and service life. These materials gradually solidify after being injected into the pavement structure, forming a hard structure that improves the pavement's load-bearing capacity and stability. General grouting materials have good fluidity and permeability, allowing them to fill voids and cracks in pavement bases and form dense structures. The selection of grouting materials should consider factors such as pavement base material, crack width, grouting pressure, etc.

[0003] Existing pavement base grouting structures mainly consist of grouting pipes and related grouting equipment. The grouting pipes are usually designed with special structures, such as woven mesh and non-woven cloth wrapped inner and outer ring skeletons, and reinforcing iron wires, to ensure their stability and durability during the grouting process. These components work together to allow the grouting pipe to withstand grouting pressure and uniformly inject grout into the pavement base. During its use, it can fill the voids and cracks in the base by injecting specific grout materials into the pavement base under high pressure, improving the base's density and load-bearing capacity. However, during its use, the grouting pipe is directly connected to the grouting machine body, and different pavements and different grouting depths require different grouting pipes, which means that the length of the grouting pipe in the existing grouting structure must be fixed. This makes the grouting pipe too long when transporting and using it in shallow layers, causing it to scatter on the road surface and causing damage to the grouting pipe, affecting its normal use and management, and also affecting its service life to some extent. Therefore, the present application provides a highway pavement base grouting structure to meet the needs. SUMMARY

[0029] The device includes a support frame 1, inside which is a connecting frame plate 2, and inside the connecting frame plate 2 is a grouting machine body 3. Grouting pipes 4 are connected to the grouting machine body 3. Two drive slide rails 5 are provided on opposite sides of the connecting frame plate 2. The same adjusting rod 6 is provided on the sliding seat of two adjacent drive slide rails 5. The drive slide rails 5 are used to drive the adjusting rods 6 to adjust their height. The grouting pipes 4 can be wound in an S-shape between the adjusting rods 6. The adjusting rods 6 are connected to adjusting plates 8 through several electric telescopic rods 7. There are three adjusting plates 8, and the three adjusting plates 8 are distributed in a semi-circular structure. Each adjusting plate 8 is connected to two electric telescopic rods 7, and the electric telescopic rods 7 are used to drive the adjusting plate 8 to move.

[0030] Before its use, the support frame body 1 can be directly pushed to be placed at the position of the highway pavement where grouting is needed, that is, the driving slide rail 5 can be controlled by the external controller, so that the driving slide rail 5 can drive the adjusting rod 6 to rise and fall, the height difference between the two driving slide rails 5 can be changed, and then the S shape of the grouting pipe 4 distributed between the two adjusting rods 6 can be effectively changed, so that the S shape can be more gentle, the size of the grouting pipe 4 sliding out of the inside of the support frame body 1 is increased, and the grouting demand of a deeper position is met. Since the height difference between the two adjusting rods 6 can be automatically adjusted, the size of the grouting pipe 4 sliding out of the inside of the support frame body 1 can also be automatically adjusted, that is, the length of the grouting pipe 4 can meet the demand of different highway pavements, thereby avoiding the possibility of scratching caused by the grouting pipe 4 being exposed outside the support frame body 1, and after the grouting pipe 4 is connected to the highway pavement, the support frame body 1 can be directly grouted by the grouting machine body 3.

[0039] The guide groove 15 is fixedly connected with a plurality of second electric push rods 17, and the free ends of the plurality of second electric push rods 17 are fixedly connected with a same moving plate 18, the side wall of the moving plate 18 is fixedly connected with a limiting piece 19, and the side wall of the guide piece 16 is provided with a limiting groove 20, and the limiting piece 19 is slidably inserted into the limiting groove 20.

[0040] After the connecting frame plate 2 is installed, the second electric push rod 17 can be controlled by an external controller, so that the second electric push rod 17 can stably push the moving plate 18 to move, at this time the limiting piece 19 on the moving plate 18 will be stably inserted into the limiting groove 20, at this time the insertion structure of the limiting piece 19 and the limiting groove 20 will limit the position of the guide piece 16, so that the position of the connecting frame plate 2 is more stable during use, avoiding the possibility of deviation during use.
