Description

Technical Field

[0001] The present invention relates to the technical field of pile foundation reinforcement structures, in particular to a pile foundation reinforcement structure for road and bridge engineering. Background Art

[0002] With the rapid development of the economy, the construction volume of road and bridge projects is getting larger and larger. Generally, a large number of pile foundations are required during the construction process of road and bridge projects. The strength of ordinary pile foundations is not high during the construction process. The pile foundations themselves are prone to tilting after long-term use, so the pile foundations need to be reinforced.

[0003] In the prior art, when reinforcing a pile foundation, a fiberglass sleeve is usually placed on the surface of the pile foundation, and then an elastic rope is tied to the surface of the fiberglass sleeve. Then, concrete is injected into the fiberglass sleeve, and the pile foundation is reinforced after waiting for the concrete to solidify. However, during the operation, a certain gap exists between the fiberglass sleeve and the pile foundation. Since the concrete is mostly injected at the same position, the concrete accumulates at the same position, causing the fiberglass sleeve to deviate to a certain extent, resulting in the phenomenon that the solidified concrete is thick on one side and thin on the other.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing pile foundation reinforcement structures on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1-15 The present invention provides a technical solution: a pile foundation reinforcement structure for road and bridge engineering, comprising two first arc frames 1, the surface of the first arc frame 1 is slidably connected to the second arc plate 11, the surface of the first arc frame 1 is mounted with a limiting arc plate 12 by bolts, the surface of the limiting arc plate 12 is slidably connected to an adjusting arc plate 15, the inner cavity of the adjusting arc plate 15 is provided with a supporting mechanism 2, a fiberglass sleeve 13 is provided at the bottom of the first arc frame 1, the fiberglass sleeve 13 is used to be sleeved on the surface of the pile foundation, the surface of the fiberglass sleeve 13 is sleeved with an elastic rope 14, it should be noted that the elastic rope 14 can be tied to the surface of the fiberglass sleeve 13 in a conventional knotting manner, an injection mechanism 3 is provided on the top of the second arc plate 11, and an adjustment mechanism 4 is provided on the top of the adjusting arc plate 15.

[0038] The supporting mechanism 2 includes a guide hole 201 opened at the top of the adjusting arc plate 15. The number of guide holes 201 is several. The inner cavity of the guide hole 201 is slidably connected with an expansion component. The inner cavity of the guide hole 201 is rotatably connected with a threaded rod 202. The surface of the threaded rod 202 cooperates with the expansion component. The surface of the threaded rod 202 is fixedly sleeved with a first gear 203. The inner cavity of the guide hole 201 is slidably connected with a toothed plate 204 that meshes with the first gear 203. One side of the toothed plate 204 passes through the adjusting arc plate 15 and is fixedly connected to the limiting arc plate 12. A driving mechanism is provided on the top of the limiting arc plate 12. By setting the supporting mechanism 2, when the adjusting arc plate 15 moves downward, the toothed plate 204 does not move, causing the first gear 203 to rotate. When the first gear 203 rotates, it drives the threaded rod 202 to rotate, thereby causing the expansion component to move, causing the expansion component to expand the fiberglass sleeve 13, thereby making the fiberglass sleeve 13 coaxial with the pile foundation.

[0039] The expansion assembly includes a moving rod 205 threadedly connected to the surface of the threaded rod 202, an adjusting rod 206 is provided at the bottom of the moving rod 205, the surface of the adjusting rod 206 and the inner cavity of the moving rod 205 are installed by bolts, the surface of the adjusting rod 206 is slidably connected to the expansion rod 207, the surface of the expansion rod 207 is fixedly connected to the reinforcement rod 208, and the number of the reinforcement rods 208 is several. By setting the expansion assembly, when the adjustment arc plate 15 moves downward, the adjusting rod 206 contracts to the inner cavity of the expansion rod 207, and the moving rod 205 drives the adjusting rod 206 and the expansion rod 207 to move, so that the expansion rod 207 can move the fiberglass sleeve 13. After the expansion is carried out and concrete is injected between the fiberglass sleeve 13 and the pile foundation, the contact area with the concrete can be increased by the reinforcement rod 208, thereby increasing the strength of the concrete, and the adjusting rod 206 is installed with one end of the moving rod 205 by bolts. When the concrete solidifies, the bolts can be removed to separate the adjusting rod 206 from the moving rod 205. It should be noted that when the adjusting arc plate 15 moves downward and contacts the fiberglass sleeve 13, the surface of the expansion rod 207 will also contact the inner wall of the fiberglass sleeve 13, and the adjusting arc plate 15 continues to move downward, and the adjusting arc plate 15 and the expansion rod 207 both maintain contact with the inner wall of the fiberglass sleeve 13.

[0040] The surface of the moving rod 205 is fixedly connected to the sliding rod 209, and the inner cavity of the guide hole 201 is provided with a sliding groove 210. The surface of the sliding rod 209 is slidably connected to the inner wall of the sliding groove 210. By setting the sliding rod 209 and the sliding groove 210 for use together, when the threaded rod 202 rotates, it will drive the moving rod 205 to move, so that the moving rod 205 drives the sliding rod 209 to slide in the inner cavity of the sliding groove 210, thereby achieving the effect of guiding the movement of the moving rod 205 and preventing the moving rod 205 from tilting.

[0041] The driving mechanism includes a support rod 211 fixedly connected to the top of the limiting arc plate 12, the top of the support rod 211 is fixedly connected to a support plate 212, the top of the support plate 212 is fixedly connected to an electric telescopic rod 213, the telescopic end of the electric telescopic rod 213 passes through the support plate 212 and is fixedly connected to the top of the adjusting arc plate 15. By setting the support rod 211, the support plate 212 and the electric telescopic rod 213 for coordinated use, the electric telescopic rod 213 is retracted to the shortest, at which time the top of the adjusting arc plate 15 is horizontally flush with the top of the limiting arc plate 12. When the electric telescopic rod 213 is started, the telescopic end of the electric telescopic rod 213 extends, thereby achieving the effect of driving the adjusting arc plate 15 to move downward.

[0042] One end of the fiberglass sleeve 13 is fixedly connected to an iron frame 214, and the surface of the fiberglass sleeve 13 is slidably connected to the inner cavity of the iron frame 214. A threaded hole 215 is provided on one side of the iron frame 214, and the inner cavity of the threaded hole 215 is threadedly connected to a positioning pin 216. The number of threaded holes 215 is several. By setting the iron frame 214, the threaded hole 215 and the positioning pin 216 for use together, when the expansion rod 207 expands the fiberglass sleeve 13, the positioning pin 216 can be rotated so that the positioning pin 216 squeezes the surface of the fiberglass sleeve 13, thereby achieving the effect of limiting one end of the fiberglass sleeve 13, ensuring that the fiberglass sleeve 13 cannot expand when concrete is added to the fiberglass sleeve 13.

[0043] The specific implementation of this embodiment is: two first arc-shaped frames 1 are connected by bolts so that the two first arc-shaped frames 1 are sleeved on the surface of the pile foundation. It should be noted that Figure 8 、 Figure 9 and Figure 10It can be seen that the inner wall of the first arc frame 1 is provided with a rubber pad to increase the friction between the first arc frame 1 and the pile foundation, and then the two second arc plates 11 are sleeved on the surface of the first arc frame 1, and the two second arc plates 11 are assembled by bolts. At this time, the limiting arc plate 12 is sleeved on the surface of the second arc plate 11, and the limiting arc plate 12 can be connected to the first arc frame 1 by bolts, and then the two adjusting arc plates 15 are connected by bolts to complete the assembly, and the cross-sections of the first arc frame 1, the second arc plate 11, the limiting arc plate 12 and the adjusting arc plate 15 are all semicircular. When the adjusting arc plate 15 moves downward, the tooth plate 204 does not move, causing the first gear 203 to rotate. When the first gear 203 moves When the screw threaded rod 202 rotates, the screw threaded rod 202 rotates, which drives the movable rod 205 to move, so that the movable rod 205 drives the adjusting rod 206 and the expansion rod 207 to move, so that the expansion rod 207 expands the fiberglass sleeve 13. After the concrete is injected between the fiberglass sleeve 13 and the pile foundation, the contact area with the concrete can be increased by the reinforcement rod 208, thereby increasing the strength of the concrete. The adjusting rod 206 and one end of the movable rod 205 are installed by bolts. When the concrete solidifies, the adjusting arc plate 15 is moved upward. At this time, the adjusting rod 206 is extended, so that the bolts on the movable rod 205 can be removed, thereby separating the adjusting rod 206 from the movable rod 205.

At this time, the fixed tube 301 is moved in a circular motion to achieve the effect of uniformly injecting the concrete. It should be noted that when connecting the two arc tubes 302, the two threaded sleeves 304 can be rotated on the surfaces of the two threaded tubes 303 respectively, so as to achieve the effect of connecting the two arc tubes 302, and the connecting tube 305 and the threaded tube 303 are sealed by the sealing ring 307.

The rod 308 and the limit platform 309 support the motor 310, and then the motor 310 is started by using an external control switch, so that the motor 310 drives the second gear 311 to rotate. Since the arc-shaped rack 312 is engaged with the second gear 311, the arc-shaped rack 312 moves in a circular manner, and the arc-shaped rack 312 drives the second arc-shaped plate 11 to move in a circular manner. By rotating the output end of the motor 310 forward and backward, the arc-shaped rack 312 drives the second arc-shaped plate 11 to move back and forth, thereby achieving the effect of evenly injecting concrete between the fiberglass sleeve 13 and the pile foundation.

[0047] The specific implementation of this embodiment is as follows: concrete is transported to the connecting pipe 305 through the hose 306, and then transported to several fixed pipes 301 through the connecting pipe 305, the motor 310 is supported by the limit rod 308 and the limit platform 309, and then the motor 310 is started by an external control switch, so that the motor 310 drives the second gear 311 to rotate.
