[0035] This embodiment discloses a construction protection component, as shown in the attached Figure 1-10As shown, it includes a main frame 1, an arched member 3 and an iron plate 12. A rubber plate 2 is attached to one side of the surface of the main frame 1. The arched member 3 is sleeved on the top of the main frame 1. A fixing bolt 4 is passed through one side of the surface of the arched member 3. Rubber strips 5 are attached to both sides of the inner surface of the main frame 1. A lifting iron block 6 is attached to the lower surface of the main frame 1. A fastener 7 is provided below the lifting iron block 6. A fixing nut 8 is welded to the lower surface of the fastener 7. Clamps 9 are provided on both sides of the fastener 7. A connector 10 is fixedly connected to one side of the clamp 9. The connector One side of the main frame 1 is fixedly connected to a steel pipe 11, one end of the steel pipe 11 is threadedly connected to an iron plate 12, a rubber pad 13 is bonded to the surface of the iron plate 12, a hexagon socket bolt 14 is passed through one side of the main frame 1, and a threaded hole 15 is opened on one end surface of the hexagon socket bolt 14. Through the arrangement of the main frame 1, rubber plate 2, arch member 3, fixing bolt 4, rubber strip 5, lifting iron block 6, fastener 7, fixing nut 8, clamp 9, connector 10, steel pipe 11, iron plate 12, rubber pad 13, hexagon socket bolt 14 and threaded hole 15 , both 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 both ends of the steel chain 17 are connected with a lock buckle 18, one end of which is connected to 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 holes are connected to each other, and 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 connections. The overall structure is detachable and easy to assemble, and 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 to the threaded hole 15. The size of the arch member 3 is consistent with the size of the road crack and is flush with the road surface. Through the setting of the fixing bolt 4, the fixing bolt 4 can fix the arch member 3, and the threaded structure of the fixing bolt 4 and the hexagon socket bolt 14 have the same locking direction.

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 grooves that have 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 with polyurethane isolation strips, the waterproof sealing is waterproof sealing with 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 applied with elastic polyurea waterproof coating;
[0044] S3. Since the waterproof repair process takes at least 5 days to complete, in order to ensure the road's traffic capacity during the construction process, it is necessary to place the main frame 1 during the process implementation interval, and then rotate the hexagon socket bolt 14. Through the cooperation of the hexagon socket bolt 14 and the fixing nut 8, the fastener 7 is driven 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. Next, the arched member 3 is placed on the outside of the main frame 1 and is tightened 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 removed as a whole, and filled with hot-mixed asphalt gravel that meets the requirements to restore the road surface.
[0048] Furthermore, the arched member 3 is hard and elastic, and the weight of the arched member 3 is ≥35 kg. Through the setting of the arched member 3, the arched structure of the arched member 3 can save materials, and at the same time has excellent force performance and high durability, and provides good protection for crack repair.
[0049] Working principle: First, when waterproofing the tunnel cracks, it is necessary to chisel and polish a regular rectangular groove at the crack, and then in the crack groove, carry out a series of waterproof structure constructions in sequence, such as applying primer, bottom layer sealing, waterproof sealing, base surface waterproof reinforcement, and waterproof layer system protection. Then, in the crack groove, on the upper surface of the waterproof structure, place the main frame 1, and then at the center 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. When 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 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, firmly fixing the overall structure of the main frame 1, and then install the arch member 3 above the main frame 1, and fix the arch member 3 by connecting the fixing bolt 4 and the threaded hole 15. Finally, nail the ground nail 19 into the excavated groove, and complete the installation of the entire protective component by pulling the steel chain 17 and the locking member 16.
[0050] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
