The main frame 1, the rubber plate 2, the arch member 3, the fixing bolt 4, the rubber strip 5, the hoisting iron block 6, the fastener 7, the fixing nut 8, the clamp 9, the connecting piece 10, the steel pipe 11, the iron plate 12, the rubber pad 13, the hexagon socket bolt 14 and the threaded hole 15 are arranged , the two sides of the fastener 7 are threadedly connected with a locking piece 16, one end of the locking piece 16 is provided with a steel chain 17, and the two ends of the steel chain 17 are connected with a lock buckle 18, one end of which is connected with a ground nail 19. First, the main frame 1 is made of high-hardness iron material as the main support of the overall structure, and then the rubber plate 2 is embedded in the upper surface of the main frame 1, and the end of the rubber strip 5 on the lower surface is embedded in the lifting iron block 6. At the same time, the fastener 7 and the clamp 9 are placed on one side of the lifting iron block 6. The fastener 7, the lifting iron block 6 and the main frame 1 are all provided with The opening of the main frame 1 is a concave structure, so that the nut of the hexagon socket bolt 14 can fit into the opening of the main frame 1, and the clamp 9, the connecting piece 10, the steel pipe 11 and the iron plate 12 are all fixed by threaded connection. The overall structure is detachable and easy to assemble. The hexagon socket bolt 14 can not only complete the extension of the iron plate 12, but also fix the main frame 1, the lifting iron block 6 and the fastener 7 together. At the same time, the threaded hole 15 on the surface of the hexagon socket bolt 14 can also cooperate with the fixing bolt 4 to fix the arch member 3.

[0036] Furthermore, one end of the fixing bolt 4 passes through the arch member 3 and is threadedly connected with the threaded hole 15.

Through the setting of the hexagon socket bolt 14, the hexagon socket bolt 14 can be directly rotated at the upper end through the corresponding tool, so that the opening on the surface of the main frame 1 can fit the size of the hexagon socket bolt 14.

[0040] A construction method for a construction protection component, the specific steps are as follows:

[0041] S1. First, a regular rectangular crack groove with a width of about 20 cm is excavated at the crack of the seepage tunnel pavement;

[0042] S2. Then, in the crack groove that has been cleaned, apply the interface agent, seal the bottom layer, seal the waterproof layer, reinforce the base surface waterproofing, and protect the waterproof layer system in sequence;

[0043] Among them, the interface agent is applied, the bottom layer is sealed by using polyurethane isolation strips, the waterproof sealing is waterproof sealing by using ZNJC high elastic structural adhesive, the base surface waterproof reinforcement includes laying ZNJC high durable waterproof sealing tape, and the waterproof layer system protection is the application of elastic polyurea waterproof coating;

[0044] S3. Since it takes at least 5 days to complete the waterproof repair process, in order to ensure the traffic capacity of the road during the construction process, it is necessary to put the main frame 1 in during the interval of the process implementation, and then rotate the hexagon socket bolt 14, and through the cooperation of the hexagon socket bolt 14 and the fixing nut 8, drive the fastener 7 to move upward at one end of the clamp 9;

[0045] S4, the clamp 9 moves to both sides under the push of the fastener 7, and at the same time drives the iron plate 12 to bulge outward, so that the iron plate 12 can squeeze the side surface of the crack through the rubber pad 13 until it is completely fixed;

[0046] S5, then put the arched member 3 on the outside of the main frame 1, and tighten it with the fixing bolts 4 to complete the installation of the protective member;

[0047] S6. Finally, when the waterproofing process is completed, the components at the cracks and grooves are taken out as a whole, filled with hot-mixed asphalt gravel that meets the requirements, and the road surface is restored.

[0048] Furthermore, the arch member 3 is hard and elastic, and the weight of the arch member 3 is ≥35kg. Through the setting of the arch member 3, the arch structure of the arch member 3 can save materials, and at the same time has excellent force performance and high durability, and has good protection for crack repair.

[0049] Working principle: First, when waterproofing the tunnel cracks, it is necessary to dig and grind out a regular rectangular groove at the crack, and then in the crack groove, carry out a series of waterproof structure constructions such as primer painting, bottom layer sealing, waterproof sealing, base surface waterproof reinforcement, and waterproof layer system protection in turn. Then, in the crack groove, on the upper surface of the waterproof structure, place the main frame 1, and then at the central opening on the surface of the main frame 1, rotate the hexagonal bolt 14, and cooperate with the fixing nut 8 to drive the fastener 7 to move upward. While the fastener 7 moves, it will prompt the clamp 9 to move to both sides. The clamp 9 will drive the steel pipe 11 and the iron plate 12 at one end of the connecting member 10 to move until the iron plate 12 is tightly fitted with the side of the crack groove through the rubber pad 13, and the overall structure of the main frame 1 is firmly fixed. Then, the arch member 3 is installed above the main frame 1, and the arch member 3 is fixed by connecting the fixing bolts 4 and the threaded holes 15. Finally, the ground nails 19 are nailed into the excavated grooves, and the installation of the entire protective component is completed by pulling the steel chain 17 and the locking member 16.

[0050] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention.
