Technical Field

[0001] The present invention mainly relates to the technical field of foundation engineering, and in particular to a method for reinforcing highway bridge foundation piles. Background Art

[0002] At present, the support of highway bridge frames is composed of foundation piles and pedestals connected to the top of the piles. If the pile body is completely buried in the soil and the bottom of the pedestal is in contact with the soil, it is called a low pedestal pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the pedestal is above the ground, it is called a high pedestal pile foundation. In the use of foundation piles, it is mostly necessary to reinforce the foundation piles to prevent cracks or collapse of the foundation piles, which may cause highway collapse.

[0003] A highway bridge foundation pile reinforcement device described in the prior art includes a ground surface, a foundation pile body is provided inside the ground surface, and four support components are provided on the outer wall of the foundation pile body, through the positioning of the square plate and the ground surface by the first bolt, the limiting and rotational cooperation of the second triangular block by the long rod, and the fixed connection between the second triangular block and the right-angle plate, through the rotational connection relationship between the first short rod and the first crank and the second crank, and the rotational cooperation between the long rod and the short rod.

[0004] Although the above technology can increase the applicability and extensiveness, so that the reinforcement component can directly reinforce the local cross-section of the foundation pile body, after a long period of use, the durability of the reinforcement component may be reduced due to environmental influences, affecting the stability. In addition, the foundation piles have other shapes besides cylindrical, which makes it inconvenient to replace the reinforcement parts according to the shape of the foundation pile.

Pull the storage shell according to the height of the foundation pile, so that the storage shell drives the installed reinforcement frame to move up through the upper shelf plate, and then fix the extended hand storage shell with the fixing bolts to determine the height of the reinforcement. Then, according to the cross-sectional shape of the foundation pile on the foundation, replace the reinforcement frame with a matching round or square one. Then, drive the winding roller to rotate through the worm and worm gear of the driving assembly to tighten the pull rope in the fixing assembly, and the pull rope drives the fixed rod to retract. At this time, place the replaced reinforcement frame between the lower shelf plate and the upper shelf plate, and rotate the handle of the driving assembly in the opposite direction to reset the fixed rod to fix the reinforcement frame, and the replacement is completed.

[0009] Step 2: Reinforcement: Place two mounting plates on both sides of the bottom of the foundation pile, so that the corresponding reinforcement frames are tightly connected.

[0013] Specifically, the technical solution of this invention is that each telescopic shell is evenly provided with a plurality of first screw holes on a side away from the base pile, the top of each storage shell is connected to the first screw hole through a fixing bolt, and each of the outer walls on both sides of the telescopic shell is provided with a movable through groove.

[0014] Specifically, the present technical solution is that each of the driving components includes two winding rollers, the two winding rollers are connected by a magnetic coupling, the ends of the two winding rollers are rotatably connected to the inner wall of the storage shell through a shaft, a protective shell is fixed to the outer wall of each storage shell, a transmission shaft is rotatably installed in each protective shell, a worm gear is fixedly installed on each transmission shaft, a worm is meshed and installed under each worm gear, and a rotary handle is provided on the side of each protective shell away from the foundation pile.

[0015] Specifically, the technical solution of this invention is that one end of each transmission shaft passes through the wall of the storage shell and is fixedly connected to the end of a winding roller, one end of each worm passes through the wall of the protective shell and is fixedly connected to the handle, and the outer ring wall of each handle is provided with friction ridges.

[0016] Specifically, the present technical solution is that each of the fixed components includes two fixed rods, and the other ends of the two fixed rods are integrally connected with ear plates on both sides, and support springs are fixed between the inner walls of the support shell and the telescopic shell and the ear plates. The interiors of the support shell and the telescopic shell are both provided with guide wheels at the end faces of the fixed rods, and the two guide wheels are provided with pull ropes, and the ends of the two pull ropes are fixedly connected to the centers of the end faces of the two fixed rods, and the other ends of the two pull ropes are respectively wound around and connected to the two winding rollers provided in the drive assembly.

[0022] The worm gear and the worm gear rotate together, and the rotation of the worm gear causes the connected winding roller to rotate, and the rotation of the winding roller loosens the wound draw rope. At the same time, the winding roller drives the other winding roller to rotate through the magnetic coupling to loosen the wound draw rope. At this time, the telescopic shell is pulled out of the storage shell according to the required reinforcement height. Under the relaxed draw rope, the telescopic shell drives the set fixing assembly to move until it moves to the specified height, and the telescopic shell and the storage shell are fixed by the fixing bolt and the first screw hole.

The inner walls of the two reinforcement frames 3 are in contact with the outer wall of the foundation pile 101. A plurality of vertical reinforcement rods 301 are evenly arranged inside the two reinforcement frames 3. The ends of the plurality of reinforcement rods 301 are fixedly connected to the inner wall of the reinforcement frame 3.

[0043] A plurality of first screw holes 2062 are evenly provided on one side of each telescopic shell 206 away from the pile 101. The top of each storage shell 205 away from the pile 101 is connected to the first screw hole 2062 through a fixing bolt 2053. A movable through groove 2061 is provided on the outer wall of each telescopic shell 206 on both sides. The upper surfaces of the two mounting plates 2 are symmetrically fixed with diagonal braces 207. The top of each diagonal brace 207 is fixedly connected to the outer wall of the storage shell 205. Four telescopic rods are provided between the two reinforcement frames 3. 4. The bottom ends of the four telescopic rods 4 are connected to the reinforcement frame 3 below by bolts. The telescopic ends of the four telescopic rods 4 are fixed with a top plate 403. A positioning groove 4031 is opened at the center of the top of each top plate 403. The lower surfaces of the two reinforcement frames 3 are fixed with a positioning block 304. Each positioning groove 4031 matches the positioning block 304. A plurality of second screw holes 401 are evenly opened on the outer walls of the telescopic ends of the four telescopic rods 4, and the outer walls of the four telescopic rods 4 are connected to the second screw holes 401 by locking bolts 402.

[0044] When reinforcing the pile 101 of the highway bridge, the staff first rotates the driving member of the driving assembly 6, so that the actuator rotates to loosen the driving member in the fixing assembly 5. At this time, the telescopic shell 206 can be pulled out from the receiving shell 205 according to the height to be reinforced. When the specified height is reached, the staff uses a tool to screw the fixing bolt 2053 from the receiving shell 205 into the corresponding first screw hole 2062 on the telescopic shell 206, so that the telescopic shell 206 is fixed to the receiving shell 205. At this time, the staff The driving member of the driving assembly 6 is rotated in the reverse direction to tighten the driving member of the fixing assembly 5 and pull the actuator of the fixing assembly 5. At this time, the staff selects a suitable reinforcement frame 3 according to the shape of the foundation pile 101, and then overlaps the reinforcement frame 3 separated in half on the lower frame plate 202 and the upper frame plate 203 by sliding the placement block 303 along the placement groove 208. Then, the driving member of the driving assembly 6 is rotated again to reset the actuator of the fixing assembly 5 and insert it into the fixing groove 3031 of the placement block 303, completing the installation of the reinforcement frame 3.

[0045] Then the staff set the two mounting plates 2 on both sides of the bottom of the foundation pile 101 respectively, so that the two lower frame plates 202 and the two upper frame plates 203, which are separated in half, are connected to form a whole, and the outer wall of the foundation pile 101 is sleeved therein, and then the mounting plate 2 is fixed to the foundation 1 by the expansion bolts 201, completing the reinforcement of the foundation pile 101 by the reinforcement frame 3. At this time, the telescopic rod 4 can be installed between the upper reinforcement frame 3 and the lower reinforcement frame 3 to improve the support effect between them. When installing the telescopic rod 4, the bottom end of the telescopic rod 4 is installed on the lower reinforcement frame 3 by bolts. Surface, then pull out the telescopic end so that the positioning groove 4031 of the top plate 403 is sleeved on the positioning block 304 on the lower surface of the reinforcement frame 3 above, and then use a tool to screw the locking bolt 402 into the corresponding second screw hole 401 on the telescopic end, which can fix the length of the telescopic rod 4, thereby achieving a supporting effect, and finally inject concrete into the assembled reinforcement frame 3 through the injection port 302. After drying, the concrete forms a whole with the foundation pile 101, further reinforcing the foundation pile 101, wherein a plurality of reinforcing rods 301 can make the connection between the concrete and the reinforcement frame 3 more firmly;

[0046] Therefore, the present application can pour concrete inside the reinforcement frame 3 after reinforcing the foundation pile 101 to increase durability and stability. At the same time, the reinforcement frame 3 can be disassembled and assembled to facilitate replacement according to the shape of the foundation pile 101.

[0047] See also Figure 3 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 9 Each driving assembly 6 includes two winding rollers 601, which are connected to each other through a magnetic coupling 607. The ends of the two winding rollers 601 are rotatably connected to the inner wall of the storage shell 205 through a shaft 602. A protective shell 2052 is fixed to the outer wall of each storage shell 205. A transmission shaft 605 is rotatably installed in each protective shell 2052. A worm gear 603 is fixedly installed on each transmission shaft 605. A worm 604 is meshed and installed below each worm gear 603. A handle 606 is provided on the side of each protective shell 2052 away from the foundation pile 101. One end of each transmission shaft 605 passes through the wall of the storage shell 205 and is fixedly connected to the end of a winding roller 601. One end of each worm gear 604 passes through the wall of the protective shell 2052 and is fixedly connected to the handle 606. The outer ring wall of each handle 606 is provided with friction ridges.

[0048] Each fixing assembly 5 includes two fixing rods 501, and the other ends of the two fixing rods 501 are integrally connected to ear plates 5011 on both sides. Support springs 502 are fixed between the inner walls of the support shell 204 and the telescopic shell 206 and the ear plates 5011. The interior of the support shell 204 and the telescopic shell 206 is provided with guide wheels 504 at the end faces of the fixing rods 501. The two guide wheels 504 are provided with pull ropes 503. The ends of the two pull ropes 503 are fixedly connected to the center of the end faces of the two fixing rods 501. The other ends of the two pull ropes 503 are respectively connected to the two ends of the two pull ropes 503 provided in the drive assembly 6. The winding rollers 601 are wound and connected, and the two fixed rods 501 are respectively arranged in the supporting shell 204 and the telescopic shell 206 and pass through the wall to be plugged into the fixed groove 3031. The two guide wheels 504 are fixedly connected to the inner bottom wall and the inner top wall of the supporting shell 204 and the telescopic shell 206 through the mounting frame plate 505. Each supporting shell 204 is connected to the storage shell 205 through a through-hole 2051. The pull rope 503 passes through the through-hole 2051. The inner walls of the supporting shell 204 and the telescopic shell 206 are in contact with the outer wall of the ear plate 5011, and the ear plate 5011 is in sliding connection with the inner wall.

[0049] The rotation of the handle 606 in the driving assembly 6 drives the connected worm 604 to rotate, the worm 604 drives the worm gear 603 to rotate, the worm gear 603 drives the connected winding roller 601 to rotate through the transmission shaft 605, and the winding roller 601 drives another winding roller 601 to rotate through the shaft 602 and the magnetic coupler 607. When the telescopic shell 206 is pulled out, the two winding rollers 601 loosen the pull ropes 503 in the telescopic shell 206 and the support shell 204 respectively. After the telescopic shell 206 is pulled out, , the internal fixed rod 501 will drive the relaxed rope 503 to be straightened, and then fixed, the handle 606 will be rotated in the opposite direction, so that the winding roller 601 connected to the transmission shaft 605 will tighten the rope 503 in the support shell 204. Due to the pulling out of the telescopic shell 206, the two ropes 503 will be relaxed to different degrees. Under the action of the magnetic coupler 607, the remaining relaxed section of the rope 503 in the telescopic shell 206 will be tightened. By observing whether the fixed rod 501 moves, it can be determined whether the rope 503 is completely tightened;

[0050] When the reinforcing frame 3 is installed, the handle 606 is still rotated to rotate the winding roller 601 through the worm gear 603 and the worm 604, tightening the pull rope 503. The tightened pull rope 503 will pull the fixed plug rod 501 along the guide wheel 504 to move, and the fixed plug rod 501 drives the ear plate 5011 to move, so that the ear plate 5011 squeezes the support spring 502 until the end of the fixed plug rod 501 is no longer in the placement groove 208, which is convenient for placing the reinforcing frame 3. After placement, the handle 606 is rotated in the direction to relax the pull rope 503. Under the elasticity of the support spring 502, the ear plate 5011 is pushed to reset, and the ear plate 5011 drives the fixed plug rod 501 to reset. When the fixed plug rod 501 is reset, it drives the relaxed pull rope 503 to move until the end of the fixed plug rod 501 is inserted into the fixed groove 3031 of the outer wall of the placement block 303, completing the installation.

[0051] The working principle of the present invention is:

[0052] When reinforcing the pile 101 of the highway bridge, the staff first rotates the driving member of the driving assembly 6, so that the rotation of the actuator rotates the handle 606 in the fixed assembly 5, which drives the connected worm 604 to rotate, and the worm 604 drives the worm wheel 603 to rotate, and the worm wheel 603 drives the connected winding roller 601 to rotate through the transmission shaft 605. The winding roller 601 drives another winding roller 601 to rotate through the shaft 602 and the magnetic coupler 607. When the telescopic shell 206 is pulled out, the two winding rollers 601 loosen the pull rope 503 in the telescopic shell 206 and the support shell 204 respectively, and the telescopic shell 206 is pulled out from the storage shell 20 according to the height required for reinforcement. 5. When the telescopic housing 206 is pulled out and reaches the specified height, the staff uses a tool to screw the fixing bolt 2053 from the storage housing 205 into the corresponding first screw hole 2062 on the telescopic housing 206, so that the telescopic housing 206 is fixed to the storage housing 205. At this time, the staff rotates the handle 606 in the opposite direction, so that the winding roller 601 connected to the transmission shaft 605 tightens the pull rope 503 in the support housing 204. Due to the different degrees of relaxation of the two pull ropes 503 caused by the pulling out of the telescopic housing 206, the remaining relaxed section of the pull rope 503 in the telescopic housing 206 is tightened under the action of the magnetic coupler 607. By observing whether the fixed insertion rod 501 moves, it is determined whether the pull rope 503 is completely tightened;

[0053] Then, after selecting a suitable reinforcement frame 3 according to the shape of the foundation pile 101, the staff will overlap the reinforcement frame 3 separated in half on the lower frame plate 202 and the upper frame plate 203 by sliding the placement block 303 along the placement groove 208. Then, the staff will rotate the handle 606 to rotate the winding roller 601 through the worm gear 603 and the worm 604 to tighten the pull rope 503. The tightened pull rope 503 will pull the fixed rod 501 along the guide wheel 504 to move, and the fixed rod 501 will drive the ear plate 5011 to move, so that the ear plate 5011 is aligned with the support The support spring 502 is squeezed until the end of the fixed plug rod 501 is no longer in the placement groove 208, which makes it easier to place the reinforcement frame 3. After placement, the handle 606 is rotated in the right direction to loosen the pull rope 503. Under the elasticity of the support spring 502, the ear plate 5011 is pushed to reset, and the ear plate 5011 drives the fixed plug rod 501 to reset. When the fixed plug rod 501 is reset, it drives the relaxed pull rope 503 to move until the end of the fixed plug rod 501 is inserted into the fixed groove 3031 of the outer wall of the placement block 303, completing the installation of the reinforcement frame 3.

[0054] Then the staff set the two mounting plates 2 on both sides of the bottom of the foundation pile 101 respectively, so that the two lower frame plates 202 and the two upper frame plates 203, which are separated in half, are connected to form a whole, and the outer wall of the foundation pile 101 is sleeved therein, and then the mounting plate 2 is fixed to the foundation 1 by the expansion bolts 201, completing the reinforcement of the foundation pile 101 by the reinforcement frame 3. At this time, the telescopic rod 4 can be installed between the upper reinforcement frame 3 and the lower reinforcement frame 3 to improve the support effect between them. When installing the telescopic rod 4, the bottom end of the telescopic rod 4 is installed on the lower reinforcement frame 3 by bolts. Surface, then pull out the telescopic end so that the positioning groove 4031 of the top plate 403 is sleeved on the positioning block 304 on the lower surface of the reinforcement frame 3 above, and then use a tool to screw the locking bolt 402 into the corresponding second screw hole 401 on the telescopic end, which can fix the length of the telescopic rod 4 and thus achieve the supporting effect. Finally, concrete is injected into the assembled reinforcement frame 3 through the injection port 302. After drying, the concrete forms a whole with the foundation pile 101, further reinforcing the foundation pile 101, wherein a number of reinforcing rods 301 can make the connection between the concrete and the reinforcement frame 3 more firmly.
