In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] Since subgrade boxes are generally reused to reduce costs, they are not fixedly connected to the ground. Instead, the subgrade boxes are directly placed on the ground so that a crane or forklift can be used to transfer the subgrade boxes to the next location. However, this results in poor grip of the subgrade boxes during the process of supporting the support frame, causing shaking and making it easy to have accidents, with low safety.

[0030] Therefore, this embodiment provides a subgrade device with strong grip. While not affecting the reuse of the subgrade box, it also has strong grip. During the hoisting process, the subgrade box will not shake, reducing the probability of accidents and having high safety.

[0031] Specifically, please refer to Figure 1 and Figure 2 , a subgrade device with strong grip includes a subgrade box 1 and a ground-gripping structure. The subgrade box 1 is placed on the ground, and the ground-gripping structure is used to connect the subgrade box 1 to the ground, improving the grip of the subgrade box 1 and preventing the subgrade box 1 from shaking during the hoisting process.

[0032] Further, please refer to Figure 3 , the subgrade box 1 includes an upper cover plate 11, a lower cover plate 12 and side plates 13. In this embodiment, there are four side plates 13. The upper cover plate 11 and the lower cover plate 12 are arranged opposite to each other. The four side plates 13 are connected end to end in sequence, and all four side plates 13 are connected between the upper cover plate 11 and the lower cover plate 12, thus forming a box body.

[0033] Still further, the ground-gripping structure includes a winding belt 21. One end of the winding belt 21 is fixed on the upper cover plate 11, and the other end of the winding belt 21 finally extends and lies flat on the ground, so as to connect the subgrade box 1 to the ground through the winding belt 21.

[0034] Exemplarily, in this embodiment, nail pins 22 are provided on the bottom surface of the part where the winding belt 21 lies flat on the ground. The winding belt 21 is unfolded, and the other end of the winding belt 21 is made to lie flat on the ground, and then the nail pins 22 are nailed into the ground. At this time, the winding belt 21 is tightened, and thus the connection between the subgrade box 1 and the ground can be realized, improving the grip of the subgrade box 1.

[0035] By providing the winding belt 21 and the nail pins 22, on the one hand, the connection between the subgrade box 1 and the ground can be realized. On the other hand, when removing the subgrade box 1, only the thumbtacks need to be pulled out and the winding belt 21 can be wound up and stored, and it can be reused.

[0036] Still exemplarily, a plurality of nail pins 22 are provided on the bottom surface of the winding belt 21, and the plurality of nail pins 22 are arranged in an array. The winding belt 21 is unfolded, and the other end of the winding belt 21 is made to lie flat on the ground, and then the plurality of nail pins 22 are all nailed into the ground. At this time, the winding belt 21 is tightened, further improving the connection strength between the subgrade box 1 and the ground and the grip of the subgrade box 1.

[0037] Optionally, multiple nails 22 are arranged at the other end of the tape 21, that is, multiple nails 22 are arranged at intervals along the width direction of the tape 21; or, multiple nails 22 are distributed throughout the tape 21, that is, multiple nails 22 are arranged at intervals along the length and width directions of the tape 21.

[0038] Preferably, after the other end of the roll belt 21 is laid flat on the ground, it is connected to a clamping ring on the ground for the first fixation, and then the nail needle 22 is further nailed into the ground.

[0039] In this embodiment, the tape 21 can be wound into a cylindrical shape, and the winding axis of the tape 21 is parallel to the width direction of the tape 21 .

[0040] Preferably, the other end of the tape 21 can be rotated clockwise to one end of the tape 21 until the tape 21 is wound into a cylindrical shape.

[0041] Further preferably, the other end of the roll belt 21 can be rotated counterclockwise to one end of the roll belt 21 .

[0042] Furthermore, the tape 21 includes a first chain 211 and a second chain 212 disposed opposite each other along its width direction. The first chain 211 and the second chain 212 are both disposed along the length direction. A plurality of connecting chains 213 are connected between the first chain 211 and the second chain 212. The connecting chains 213 are spaced apart along the length direction of the tape 21. Specifically, the staples 22 are connected to the connecting chains 213.

[0043] Optionally, the distances between two adjacent connecting chains 213 are the same, so as to control the uniform force on the tightened belt 21 .

[0044] Preferably, at least one nail 22 is connected to the connecting chain 213 located at the outermost side and away from the roadbed box 1 to ensure that the other end of the coiled belt 21 can be connected to the ground.

[0045] The present embodiment provides a roadbed device with strong grip, including a plurality of rolls 21, which are evenly spaced around the roadbed box 1. That is, at least one roll 21 is provided on each of the four sides of the roadbed box 1 to ensure that the roadbed box 1 is evenly stressed and will not roll over, thereby improving safety performance.

[0046] Furthermore, the upper cover 11 is provided with a receiving groove 111, in which the rolled tape 21 can be stored after being wound, so as to prevent the unrolled rolled tape 21 from affecting the transfer of the roadbed box 1. Preferably, the receiving groove 111 is provided on the outer side of the upper cover 11 to prevent affecting the use of the roadbed box 1.

[0047] Further preferably, when at least one tape 21 is provided on each of the four sides of the roadbed box 1, a storage groove 111 is provided around the upper cover plate 11, and the tapes 21 on the same side can be stored in the same storage groove 111.

[0048] Optionally, one end of the tape 21 is fixed to the bottom of the storage groove 111, thereby improving the flatness of the roadbed box 1.

[0049] Specifically, the roadbed box 1 is further provided with a fixing band 14. One end of the fixing band 14 is fixedly connected to one of the side walls of the storage groove 111. The fixing band 14 is arranged along the width direction of the tape 21, and the other end of the fixing band 14 is clamped to the opposite side wall of the storage groove 111. The tape 21 is pressed against the bottom of the storage groove 111 by the fixing band 14 to prevent it from being uncontrollably unfolded due to shaking during transfer.

[0050] A roadbed device with strong grip provided in this embodiment can, on the one hand, realize the connection between the roadbed box 1 and the ground by providing the tape 21 and the nail needles 22, improve the grip of the roadbed box 1, reduce the probability of accidents, and improve construction safety; on the other hand, when removing the roadbed box 1, only the thumbtacks need to be pulled out and the tape 21 can be wound and stored. The cost is low and it can be reused.
