Embodiment Construction
[0011] exist figure 1 , figure 2 and image 3 Among them, the packing block 3 of the expansion joint is made of highly elastic materials, such as rubber and high-elastic special asphalt. In the bridge expansion joint made of packing block 3, the array is arranged with blocks 1 of equal height, and the number of rows in the figure is equal to 3. Because is a triangular array, the number of columns in the middle row is equal to 8, and the number of columns in the next two rows is equal to 9. The top surface of the equal-height block 1 is equal to the road surface, and the effect is to bear the heavy pressure of the wheel to keep the road surface level smooth, and the constraint on the elastic expansion and contraction of the filler block 3 in the expansion joint is relatively small. The side of the equal height block 1 has a rough surface, or has a boss or a concave hole, or has a zigzag shape or is evenly distributed with a wing plate 1.1, or has a filling hole 1.2, and the ...
