According to the box culvert cushion block, the problem that two wedge blocks are easy to separate when the height of the box culvert is adjusted is solved, and the effect of convenient and fast box culvert height adjustment is achieved.

The technical scheme in the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:

as shown in fig. 1-3, the box culvert cushion block comprises a first cushion block and a second cushion block, and a third cushion block is arranged between the first cushion block and the second cushion block;

the third cushion block is arranged as a wedge block;

Through the setting of first cushion, second cushion and third cushion, when utilizing the third cushion to realize the box culvert height, combine first cushion, second cushion and third cushion together, solved prior art, two wedges pile up together, because do not have the part of connecting between two wedges, lead to easy landing between two wedges, cause the inconvenient problem of regulation.

In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.

Examples:

as shown in fig. 1, a box culvert spacer block comprises a first spacer block 10 and a second spacer block 11, wherein the second spacer block 11 is in sliding connection with the first spacer block 10 along the vertical direction through a supporting block 12, the first spacer block 10 is positioned right below the second spacer block 11, one end, close to the second spacer block 11, of the supporting block 12 is fixedly connected with the second spacer block 11, and one end, close to the first spacer block 10, of the supporting block 12 is in sliding connection with the first spacer block 10 through a mounting groove 101.

By providing the support block 12 and the mounting groove 101, the support block 12 cannot be separated from the inside of the mounting groove 101 when the support block 12 slides inside the mounting groove 101.

As shown in fig. 2, the second cushion block 11 is provided with a bidirectional threaded rod 112 through a connecting block, the bidirectional threaded rod 112 is rotationally connected with the connecting block, two third cushion blocks 13 are arranged between the first cushion block 10 and the second cushion block 11, the two third cushion blocks 13 are symmetrically arranged about a symmetry axis of the supporting block 12, the third cushion blocks 13 are wedge-shaped blocks, one surface, close to the third cushion blocks 13, of the second cushion block 11 is set as a horizontal plane, the third cushion blocks 13 are attached to the second cushion blocks 11, the wedge-shaped surfaces of the first cushion block 10 and the third cushion blocks 13 are attached to the bidirectional threaded rod 112, the two third cushion blocks 13 are in threaded connection with the sleeve blocks 131, a fixing rod 111 is fixedly connected to the second cushion block 11, and the third cushion blocks 13 are in sliding connection with the second cushion blocks 11 through the fixing rod 111.

One end of the bidirectional threaded rod 112 is fixedly connected with a rocker 113, and a clamping groove 114 is formed in the rocker 113.

When the first cushion block 10, the second cushion block 11 and the third cushion block 13 are utilized to carry out box culvert height adjustment, firstly, the cushion blocks are required to be respectively placed at four bottom corners of the bottom end of the box culvert, after the whole cushion block is placed, the second cushion block 11 arranged on the cushion block is contacted with the bottom of the box culvert, and as one surface of the second cushion block 11 contacted with the bottom end of the box culvert is a horizontal surface, the arrangement of the second cushion block 11 can promote the second cushion block 11 to support the box culvert in the process, and the box culvert can keep stability.
