Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5 As shown in the figure, a polymer corrugated sheet for tunnel reinforcement according to an embodiment of the present invention includes a first corrugated sheet 1. The sidewall of the first corrugated sheet 1 has a slot 11 and a boss 12, which are correspondingly arranged. A first skeleton 13 is fixedly connected inside the first corrugated sheet 1. A first through groove 14 is formed on the sidewall of the first skeleton 13, and multiple first through grooves 14 are arranged in a linear array. A connecting block 15 is provided between adjacent first corrugated sheets 1. A connecting cylinder 16 is fixedly connected to the sidewall of the connecting block 15, and two connecting cylinders 16 are symmetrically arranged. A reinforcing block 17 is fixedly connected inside the connecting cylinder 16. During operation, the reinforcing block 17 fixed inside the connecting cylinder 16 strengthens the structural strength of the connecting cylinder 16. During the assembly of the corrugated sheet, workers can use the correspondence between the slot 11 and the boss 12 to connect the same water... Two first corrugated plates 1 on a plane are spliced ​​together. At the same time, workers can connect adjacent first corrugated plates 1 on different horizontal planes by inserting connecting cylinders 16 on both sides of the connecting block 15 into the first corrugated plates 1 respectively. The first frame 13 fixed inside the first corrugated plate 1 can provide support for the first corrugated plate 1 from the inside. Since the first through groove 14 is opened on the side wall of the first frame 13, the contact area between the first corrugated plate 1 and the first frame 13 will be increased, and the connection strength between the two will be increased accordingly. Through the above structure, the slot 11 and the boss 12 are set to connect adjacent first corrugated plates 1 on the horizontal plane, and the connecting block 15 and the connecting cylinder 16 are set to connect first corrugated plates 1 on different horizontal planes. Finally, by splicing multiple first corrugated plates 1, support is provided for the inner sidewall of the tunnel, which is conducive to improving the work efficiency of tunnel support operation.

[0026] like Figure 1 and Figure 3As shown, the system includes a second waveform plate 2, a third waveform plate 21 at the bottom of the second waveform plate 2, and the second and third waveform plates 21 are respectively sized to correspond to the first waveform plate 1. A second frame 22 is fixedly connected inside the second waveform plate 2, and a rotating groove 23 is formed at the bottom of the second frame 22. A third frame 24 is fixedly connected inside the third waveform plate 21, and a rotating block 25 is fixedly connected to the top of the third frame 24. The rotating block 25 is rotatably connected inside the third frame 24. During operation, because the rotating block 25 fixed to the top of the third frame 24 is rotatably connected to the rotating groove 23 at the bottom of the second frame 22, the second waveform plate 2 and the third waveform plate 21 will form an angle. When installing the corrugated plate, workers can first assemble multiple first corrugated plates 1, and then connect the second corrugated plate 2 to the first corrugated plate 1 using connecting blocks 15 and connecting cylinders 16. After connecting the second corrugated plate 2 to the first corrugated plate 1, workers can rotate the third corrugated plate 21 until it contacts the side wall of the second corrugated plate 2. Through the above structure, the second frame 22 and the third frame 24 are rotatably connected, so that the second corrugated plate 2 and the third corrugated plate 21 are rotatably connected, which enhances the flexibility of the corrugated plate, helps to reduce the construction difficulty of the corrugated plate, and improves the construction efficiency.

[0027] like Figures 1 to 4 As shown, a first fixing cylinder 3 and a second fixing cylinder 31 are fixedly connected to the side wall of the first frame 13; a first fixing cylinder 3 and a second fixing cylinder 31 are fixedly connected to the side walls of the second frame 22 and the third frame 24; the first fixing cylinder 3 and the second fixing cylinder 31 are arranged correspondingly; a transverse rib 32 is provided between the first fixing cylinder 3 and the second fixing cylinder 31; during operation, after the first corrugated plate 1, the second corrugated plate 2, and the third corrugated plate 21 are spliced, the workers can insert the transverse rib 32 into the first fixing cylinder 3 and the second fixing cylinder 31 until the transverse rib 32 simultaneously contacts multiple first corrugated plates 1, second corrugated plates 2, and third corrugated plates 21; through the above structure, the first fixing cylinder 3, the second fixing cylinder 31, and the transverse rib 32 are set to connect multiple adjacent first corrugated plates 1, adjacent second corrugated plates 2, and connected third corrugated plates 21, thereby enhancing the overall stability of the corrugated plate tunnel reinforcement structure and protecting tunnel safety.

[0028] like Figure 5As shown, a fourth frame 4 is fixedly connected inside the connecting block 15, connecting cylinder 16, and reinforcing block 17; a second through groove 41 is provided on the side wall of the fourth frame 4, and multiple second through grooves 41 are arranged in a corresponding manner; during operation, the fourth frame 4 fixed inside the connecting block 15 and connecting cylinder 16 can strengthen the structural strength of the connecting block 15, connecting cylinder 16, and reinforcing block 17 by supporting them inside the connecting block 15, connecting cylinder 16, and reinforcing block 17. The second through groove 41 serves to increase the contact area between components; through the above structure, the fourth frame 4 and the second through groove 41 enhance the structural strength of the connecting block 15, connecting cylinder 16, and reinforcing block 17, which helps to prevent damage during stress and enhances the overall stability of the corrugated plate structure.

[0029] like Figures 1 to 4 As shown, reinforcing protrusions 5 are fixed to the side walls of the first corrugated plate 1, the second corrugated plate 2, and the third corrugated plate 21, and the multiple reinforcing protrusions 5 are arranged in a linear array; skeleton protrusions 51 are fixed to the side wall of the first frame 13; skeleton protrusions 51 are fixed to the side walls of the second frame 22 and the third frame 24, respectively; during operation, the skeleton protrusions 51 fixed to the side walls of the first frame 13, the second frame 22, and the third frame 24 can enhance the shear resistance of the first frame 13, the second frame 22, and the third frame 24, and the reinforcing protrusions 5 fixed to the side walls of the first corrugated plate 1, the second corrugated plate 2, and the third corrugated plate 21 can enhance the structural strength of the first corrugated plate 1, the second corrugated plate 2, and the third corrugated plate 21; through the above structure, the reinforcing protrusions 5 and the skeleton protrusions 51 enhance the shear resistance of the corrugated plate structure, which is beneficial to enhancing the structural strength of the corrugated plate and extending the service life of the corrugated plate support structure.

[0030] like Figures 1 to 4 As shown, the first corrugated plate 1, the second corrugated plate 2, the third corrugated plate 21, the reinforcing protrusion 5, the connecting block 15, the connecting cylinder 16, and the reinforcing block 17 are made of high-molecular polymer material. During operation, the high-molecular polymer material, which is cured under high temperature and pressure, can improve the structural strength of the first corrugated plate 1, the second corrugated plate 2, the third corrugated plate 21, the reinforcing protrusion 5, the connecting block 15, the connecting cylinder 16, and the reinforcing block 17. Through the above structure, the use of high-molecular polymer material for the first corrugated plate 1, the second corrugated plate 2, the third corrugated plate 21, the reinforcing protrusion 5, the connecting block 15, the connecting cylinder 16, and the reinforcing block 17 enhances their structural strength and corrosion resistance, which is beneficial to extending the service life of the corrugated plate support structure and improving its support capacity.

[0031] like Figures 2 to 4As shown, the first frame 13, the second frame 22, the third frame 24, the fourth frame 4, and the frame protrusion 51 are made of basalt fiber. During operation, the use of basalt fiber in the first frame 13, the second frame 22, the third frame 24, the fourth frame 4, and the frame protrusion 51 can take advantage of the high structural strength and low density of basalt fiber. Through the above, the use of basalt fiber in the first frame 13, the second frame 22, the third frame 24, the fourth frame 4, and the frame protrusion 51 enhances their structural strength and reduces their weight, which helps to reduce the load on the corrugated plate support structure and improve its stability.

[0032] During operation, the reinforcing block 17 fixed inside the connecting cylinder 16 strengthens the structural strength of the connecting cylinder 16. During the assembly of the corrugated plates, workers can use the correspondence between the slot 11 and the boss 12 to splice two first corrugated plates 1 on the same horizontal plane. Simultaneously, workers can connect adjacent first corrugated plates 1 on different horizontal planes by inserting the connecting cylinders 16 on both sides of the connecting block 15 into the first corrugated plates 1. The first frame 13 fixed inside the first corrugated plate 1 provides internal support for the first corrugated plate 1. Because the first frame 13 has a first through slot 14 on its side wall, the first corrugated plate 1 and the first frame... The contact area of ​​13 will increase, and the bonding strength between the two will increase accordingly. Since the rotating block 25 fixed to the top of the third frame 24 is rotatably connected to the rotating groove 23 at the bottom of the second frame 22, the second waveform plate 2 and the third waveform plate 21 will be rotatably connected. When installing the waveform plates, the workers can first complete the splicing of multiple first waveform plates 1, and then connect the second waveform plate 2 and the first waveform plate 1 with the connecting block 15 and the connecting cylinder 16. After connecting the second waveform plate 2 and the first waveform plate 1, the workers can rotate the third waveform plate 21 until the third waveform plate 21 contacts the side wall of the second waveform plate 2, thus completing the connection of the first waveform plate 1 and the second waveform plate 21. After the splicing of plate 2 and the third corrugated plate 21, the workers can insert the horizontal ribs 32 into the first fixing cylinder 3 and the second fixing cylinder 31 until the horizontal ribs 32 simultaneously contact the multiple first corrugated plates 1, second corrugated plates 2, and third corrugated plates 21. The fourth frame 4, which is fixed inside the connecting block 15 and the connecting cylinder 16, can strengthen the structural strength of the connecting block 15, the connecting cylinder 16, and the reinforcing block 17 by supporting them inside the connecting block 15, the connecting cylinder 16, and the reinforcing block 17. The second through groove 41 serves to increase the contact area between components. The frame protrusions 51 fixed on the side walls of the first frame 13, the second frame 22, and the third frame 24 can strengthen the first frame 13. The shear resistance of the second skeleton 22 and the third skeleton 24 is enhanced. The reinforcing protrusion 5 fixed to the side wall of the first wave plate 1, the second wave plate 2, and the third wave plate 21 can enhance the structural strength of the first wave plate 1, the second wave plate 2, and the third wave plate 21. The high-molecular polymer material cured by high temperature and high pressure can improve the structural strength of the first wave plate 1, the second wave plate 2, the third wave plate 21, the reinforcing protrusion 5, the connecting block 15, the connecting cylinder 16, and the reinforcing block 17. The first skeleton 13, the second skeleton 22, the third skeleton 24, the fourth skeleton 4, and the skeleton protrusion 51 made of basalt fiber material can give full play to the advantages of high structural strength and low density of basalt fiber material.
