[0026] Refer to Figures 1-5, A tunnel protection structure adjacent to a subway line, including two wall-attaching devices arranged symmetrically. Each of the two wall-attaching devices includes two upright devices arranged symmetrically. The upright device includes a column 1. A threaded groove 2 is provided on the lower side wall of the column 1. A threaded column 3 is threadedly connected in the threaded groove 2. The lower end surface of the threaded column 3 is rotatably connected to a floor 4. One end of the four threaded columns 3 close to the floor 4 is fixedly connected to a protection disc 28. This facilitates the user to fix the threaded column 3 through the protection disc 28, greatly facilitating the user's operation. A plurality of spikes 5 are fixedly connected to the side wall of the floor 4 away from the threaded column 3. Threaded holes 24 are provided on all four floors 4. Bolts 25 are threadedly connected in the four threaded holes 24. One end of the four bolts 25 away from the top surface cloth 14 is fixedly connected to a pointed head 26. With the help of the pointed head 26, the bolt 25 can be conveniently inserted into the ground to complete the auxiliary fixation work of the floor 4, thus greatly improving the stability of the support and protection of the entire device. Between the two columns 1 in the wall-attaching device, there are two crossbeam devices arranged symmetrically. Side plates 6 are fixedly connected to the side walls of the two columns 1 close to each other. Cylinders 7 are fixedly connected to the upper side walls of the two side plates 6. A cross column 8 is rotatably connected to the two cylinders 7 together. A sliding groove 9 is provided on the side wall of the cross column 8. A sliding block 10 is slidably connected in the sliding groove 9. A side surface cloth 11 is fixedly connected to the four sliding blocks 10 together. Card slots 12 are provided on the upper end surfaces of the four columns 1 in the two wall-attaching devices. Clamping blocks 13 are slidably connected in the four card slots 12. A top surface cloth 14 is fixedly connected to the four clamping blocks 13 together. The top surface cloth 14 can cooperate to complete the upper support work and can also complete the interception work of the stones falling from above, greatly ensuring the smooth progress of the protection work;

[0027] Both of the two sliding grooves 9 are arranged in a T shape, and the shapes of the four sliding blocks 10 respectively match the two sliding grooves 9. The T-shaped arrangement enables the sliding blocks 10 to slide more stably within the sliding grooves 9, thereby better and more stably completing the support work for the side cloth 11, and thus smoothly completing the side protection work. On the side walls of the four columns 1 close to each other, top devices are provided. The top device includes two fixing plates 15 fixedly connected to the column 1. A round rod 16 is fixedly connected between the two fixing plates 15. An auxiliary column 17 is rotatably connected to the round rod 16. A threaded port 18 is provided on the side wall of the auxiliary column 17 away from the round rod 16. A threaded rod 19 is threadedly connected within the threaded port 18.

A threaded bar 22 is threadedly connected within the threaded hole 21. On the side walls of the four threaded bars 22 away from the top cloth 14, turntables 27 are fixedly connected respectively. The turntables 27 facilitate the user to rotate the threaded bars 22. A top block 23 is fixedly connected to the side wall of the threaded bar 22 close to the top cloth 14. All four top blocks 23 are made of rubber material. The top block 23 made of rubber material can, by virtue of its own elasticity, resist the top cloth 14 without damaging the top cloth 14, greatly ensuring the smooth progress of the protection work.

[0028] A protection construction method for a tunnel protection structure adjacent to a subway line includes the following steps:

[0029] S1. First, transport each component of the entire device to the designated position in the tunnel. Then, fix the floor 4 at the designated position by inserting the spikes 5 on the floor 4 into the ground according to the designated distance position. Then, rotate the corresponding bolts 25. Then, by virtue of the threaded connection between the bolts 25 and the threaded holes 24, when the bolts 25 rotate, the pointed heads 26 are pushed into the ground, thereby more stably completing the fixing work of the floor 4, and then smoothly completing the corresponding fixing work of the four threaded columns 3 and the four columns 1.

[0030] S2. Then take out one of the side cloths 11, insert the two ends of the two cross bars 8 on the side cloth 11 into the four cylinders 7 respectively. Then repeat the above steps to complete the installation work of the other side cloth 11. By inserting the four clamping blocks 13 into the clamping grooves 12 on the four columns 1 respectively, the fixed installation work of the top cloth 14 is smoothly completed.

[0031] S3. With one of the auxiliary columns 17 selected, the auxiliary column 17 is rotated to a suitable angle by means of the round rod 16. Then, the threaded connection between the threaded rod 19 and the threaded port 18 pushes the auxiliary block 20 to a suitable position. Then, the turntable 27 is rotated, which drives the threaded bar 22 to rotate. In this way, through the threaded connection between the threaded bar 22 and the threaded hole 21, the top block 23 is pushed upward. Then, with the upward movement of the top block 23, the top cloth 14 above is lifted. Then, repeat the above steps to complete the lifting work of the other three top blocks 23.

[0032] S4. Finally, the four protection discs 28 can be rotated, which drives the threaded columns 3. During the rotation of the threaded columns 3, the threaded connection between the threaded columns 3 and the threaded grooves 2 enables the upright columns 1 to rise to a high position. Then, the top cloth 14 is smoothly pushed up to a high position to complete the supporting work. In this way, the assembly work of the entire device is conveniently completed. If disassembly is required, just operate in the reverse direction, which greatly facilitates the user.

[0033] In the present invention, when the user uses the device, first, each component of the entire device is transported to the designated position in the tunnel. Then, the floor 4 is fixed at the designated position by inserting the spikes 5 on the floor 4 into the ground according to the designated distance position. Then, the corresponding bolt 25 is rotated, and then, by means of the threaded connection between the bolt 25 and the threaded hole 24, the bolt 25 is pushed to insert the pointed head 26 into the ground during rotation, thereby more stably completing the fixing work of the floor 4. Subsequently, the corresponding fixing work of the four threaded columns 3 and the four columns 1 is successfully completed. Then, one of the side cloths 11 is taken out, and the two ends of the two cross columns 8 on the side cloth 11 are respectively inserted into the four cylinders 7. Then, the above steps are repeated to complete the installation work of the other side cloth 11. In this way, the side protection work can be successfully completed by means of the side cloth 11. By inserting the four clamping blocks 13 into the clamping grooves 12 on the four columns 1 respectively, the fixed installation work of the top cloth 14 is successfully completed. By selecting one of the auxiliary columns 17 and then rotating the auxiliary column 17 to a suitable angle by means of the round rod 16, then the threaded connection between the threaded rod 19 and the threaded port 18 pushes the auxiliary block 20 to a suitable position. Then, the turntable 27 is rotated, and then the threaded bar 22 is driven to rotate. In this way, by means of the threaded connection between the threaded bar 22 and the threaded hole 21, the top block 23 is pushed to rise. Then, with the rise of the top block 23, the top cloth 14 above is lifted. Then, the above steps are repeated to complete the lifting work of the other three top blocks 23. In this way, the top cloth 14 can be lifted to complete the support work above, and at the same time, the top cloth 14 can be in a state where the center is high and the surrounding is low. If a stone falls, it can roll to the surrounding and fall smoothly without accumulating on the top cloth 14, greatly ensuring the safety of the top. Finally, the four protection disks 28 can be rotated, and then the threaded columns 3 are driven. During the rotation of the threaded columns 3, the columns 1 can be lifted to a high position by means of the threaded connection between the threaded columns 3 and the threaded grooves 2, and then the top cloth 14 is successfully pushed to rise to a high position to complete the support work. In this way, the assembly, support and protection work of the entire device is completed conveniently and quickly, greatly facilitating the user's use.

[0034] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
