AI Technical Summary
In the pavement drag and drop laying system, due to the considerable safety margin, large pitch and large width of the pavement design, there are obstacles between the upper pavement panel and the lower pavement panel, which makes it difficult to effectively raise the pavement surface, increasing the drag force.
The function of following airbag is adopted to lift the upper pavement through the airbag to reduce the drag force required to drag the pavement. The specific implementation includes winding the joint-shaped flexible airbag on the drag roller, and injecting gas into the airbag through the gas storage cylinder module, causing the airbag to bulge and support the upper pavement module.
The road surface is raised by the airbag, which reduces dragging force and improves the efficiency and safety of road surface laying.

The segmented flexible airbag 600 is released as the lower pavement module 300 is extended.

The lower pavement module 300 is formed, and as the tractor 400 drives the central roller 510 and the limiting bracket 530 to roll on the shallows, the pavement module 300 stored in the storage integrated box 210 is slid along the slide 220 to leave the storage integrated box 210 under the drag of the central roller 510 and the limiting bracket 530, and the tractor 400 continues to drag the dragging roller 500, and the dragging roller 500 turns the upper pavement module 300 to the lower layer for paving, and continuously releases the segmented flexible airbags 600 for inflation until some pavement modules 300 are completely paved.
