[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1-Figure 3 As shown, the bridge gap reinforcement structure of this embodiment includes a casting rod 1, a reinforcement rod 2, a blocking net 3 and a reinforcement plate 4, and the blocking net 3 is laid on the inner wall of the gap; at least one pair of reinforcement rods 2 are obliquely and symmetrically arranged on both sides of the gap, the top of the reinforcement rod 2 is fixed to the bottom of the reinforcement plate 4, and the bottom of the reinforcement rod 2 successively penetrates the bridge 5 and the blocking net 3 and then enters the gap; the bottom of the casting rod 1 penetrates the reinforcement plate 4 and then extends to the inside of the gap, and the outer wall of the casting rod 1 is fixed to the reinforcement plate 4; a connecting male head is provided at the bottom of the casting rod 1, and a connecting female head is provided at the bottom of the reinforcement rod 2, and the connecting male head and the connecting female head are gap-matched.

[0021] When using the device, first clean the inside of the gap, and then lay the blocking net 3 in the gap to prevent new debris from falling into the gap and affecting subsequent operations; then, drive the reinforcing rod 2 obliquely on both sides of the gap, so that the end of the reinforcing rod 2 connected to the female head enters the gap. After the reinforcing rod 2 is driven in, the top of the reinforcing rod 2 is fixed with the reinforcing plate 4, and the reinforcing plate 4 also has the effect of blocking the gap; then, the pouring rod 1 passes through the reinforcing plate 4 and is driven into the gap. During the lowering of the pouring rod 1 When the casting rod 1 passes through the gap between the two reinforcement rods 2, the two sides of the connecting male head are forced to rotate toward the middle, and the connecting female head rotates toward the gap side; when the casting rod 1 passes through the gap between the two reinforcement rods 2, the connecting male head and the connecting female head are reset. At this time, if the casting rod 1 moves upward, the connecting female head will restrict the casting rod 1 through the connecting male head, preventing the casting rod 1 from moving upward; and because the gaps are mostly V-shaped, the casting rod 1 cannot continue to move deeper into the gap, thereby fixing the casting rod 1.

[0022] Furthermore, the connecting male head includes a first torsion spring 12 and a first rotating head 14 , the bottom of the first rod body 11 of the casting rod 1 is rotatably connected to the first torsion spring 12 , and the first torsion arms 13 at both ends of the first torsion spring 12 are respectively fixed to a first rotating head 14 .

[0023] The first rotating head 14 is an arc-shaped upward structure. The two first torsion arms 13 of the first torsion spring 12 are both facing upward in the initial state. Therefore, the first torsion arm 13 will only rotate downward when a large force is applied to the first torsion arm 13, and the first torsion arm 13 only needs a small force to rotate toward the center. Through the structure connecting the first torsion spring 12 and the first torsion arm 13, when the first rotating head 14 is subjected to force, the first rotating head 14 can rotate toward the direction of the first shaft 11 more easily.

[0024] Furthermore, the connecting female head includes a second rotating head 22 and a second torsion spring 23. The bottom of the second rod body 21 of the reinforcement rod 2 is rotatably connected to the second torsion spring 23. The second torsion arm 24 at one end of the second torsion spring 23 is fixed to the second rotating head 22, and the other end of the second torsion spring 23 is fixed to the second rod body 21. When reinforcement is completed, the first rotating head 14 abuts against the second rotating head 22.

[0025] The second rotating head 22 is an arc-shaped downward structure, which is connected to the second torsion arm 24 through the second torsion spring 23. When the second rotating head 22 is subjected to force, the second rotating head 22 can easily rotate toward the inner wall of the gap; through the cooperation of the first torsion arm 13 and the second torsion arm 24, the casting rod 1 can pass through the gap between the two reinforcement rods 2 from top to bottom more conveniently, while it is difficult for the casting rod 1 to pass through the gap between the two reinforcement rods 2 from bottom to top.

[0026] Furthermore, a grouting hole 15 is provided on the surface of the portion of the casting rod 1 that enters the gap.

[0027] Concrete is poured into the gap through the grouting holes 15.

[0028] The method of using the utility model is:

[0029] When using this device, first clean the inside of the gap, and then lay a blocking net 3 in the gap to prevent new debris from falling into the gap and affecting subsequent operations; then, the reinforcing rods 2 are obliquely driven into the gap on both sides, so that the end of the reinforcing rod 2 connected to the female head enters the gap. After the reinforcing rod 2 is driven in, the top of the reinforcing rod 2 is fixed with the reinforcing plate 4, and the reinforcing plate 4 also has the effect of sealing the gap; then the casting rod 1 is passed through the reinforcing plate 4 and driven into the gap. During the lowering of the casting rod 1, when the casting rod 1 passes through the gap between the two reinforcing rods 2, the first rotating head 14 is forced to rotate toward the middle, and the second rotating head 22 rotates toward the side of the gap; when the casting rod 1 passes through the gap between the two reinforcing rods 2, the first rotating head 14 and the second rotating head 22 are reset. After the casting rod 1 is fixed, an external machine is used to grout the casting rod 1, and concrete enters the gap through the grouting hole 15. After the concrete hardens, the reinforcement of the gap is completed.

[0030] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
