Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of bridge jacking, and in particular to a large-span steel structure bridge with an anti-collision structure and a jacking construction process. Background Art
[0002] When constructing a long-span bridge, most of the methods used are cast-in-place scaffolding, prefabricated hoisting, and cantilever construction. However, these methods require long-term scaffolding formwork, steel bars, and concrete pouring operations above the upper span route. However, when constructing bridges with particularly large spans, it is generally impossible to set up scaffolding formwork underground for such bridges. When building a large-span bridge, a jacking construction process is used. During the jacking process, tracks and sliding shoes are first set on the piers, the guide beam frame is pushed to the sliding shoe, and then the hydraulic rod is controlled to support the sliding shoe. The guide beam frame is supported by the hydraulic rod, and the moving sliding shoe drives the entire guide beam frame to move.
[0003] However, the guide beam frame will deform due to its own gravity when being pushed, and the moving distance and height of the guide beam frame need to be precisely controlled. Otherwise, the guide beam frame will hit the sliding shoe, causing the guide rail to deform and making the sliding shoe unable to move. In addition, there is no good fixing mechanism between the existing sliding shoe and the hydraulic rod. When the sliding shoe drives the guide beam frame to move, it is easy to cause the sliding shoe and the hydraulic rod to separate, causing the guide beam frame to lose support.

[0014] A jacking construction process for a long-span steel structure bridge with an anti-collision structure comprises the following steps: Step 1: Before the guide beam frame is pushed, the limiting teeth are clamped into the limiting grooves to limit and fix the telescopic plate, and the position height of the mounting plate is controlled by controlling the second hydraulic rod so that the buffer plate faces the anti-collision impact mechanism; Step 2: During the push, the impact column hits the buffer plate, and the impact force is buffered by the buffer plate, and the impact column is guided, so that the guide beam frame is lifted, and the impact column moves to the positioning groove, so that the first pressure sensing module feels the pressure and transmits the signal to the second hydraulic rod, and the second hydraulic rod drives the mounting plate to move upward, the impact column squeezes the squeezing column, and the squeezing bead squeezes the control bead, so that the second pressure sensing module has pressure, and the data is transmitted to the first hydraulic rod; Step 3: When the pushing angle is not appropriate, the impact column hits the buffer plate, thereby driving the impact plate to impact the detection plate, which will cause the force applied by the impact plate to be greater than the force of the detection plate, thereby causing the detection plate to break, causing the lower end of the impact plate to be detected by the infrared sensor, controlling the pushing to stop, and avoiding subsequent collisions; Step 4: After the jacking is completed correctly, the first hydraulic rod rests on the upper end of the sliding shoe, thereby lifting the entire guide beam frame.

When the sliding shoe slides along the track, the guide beam frame and the sliding shoe can be prevented from separating and the guide beam frame can be prevented from falling, thereby ensuring the normal progress of the entire pushing operation.

[0024] An adsorption column 14 is fixedly connected to the upper end of the connecting plate 12, an insulating tube 15 is fixedly connected to the middle of the guide beam frame 1, an electromagnet 16 is fixedly connected to the interior of the insulating tube 15, the adsorption column 14 is an iron column, and the upper end of the adsorption column 14 is slidably connected to the insulating tube 15. During the pushing operation, if the pushing angle of the guide beam frame 1 is incorrect, the electromagnet 16 will be energized to generate adsorption force, thereby moving the adsorption column 14 and the connecting plate 12 upward.
[0025] The upper end of the telescopic plate 111 is provided with a plurality of limit grooves 112, and the lower end of the connecting plate 12 is fixedly connected with a plurality of limit teeth 13, and the limit teeth 13 and the limit grooves 112 correspond one to one. During the top-pushing construction, the limit teeth 13 are clamped in the limit grooves 112, and the impact column 114 is fixedly connected to the top of the telescopic plate 111. The impact column 114 and the telescopic plate 111 form a T-shaped structure. Both ends of the impact column 114 are rotatably connected with a rotating ring 113, so that the telescopic plate and the guide beam frame 1 are connected into a whole. During the top-pushing operation, the impact column 114 hits the buffer plate 171, and the rotating ring 113 can reduce the friction. When the top-pushing angle of the guide beam frame 1 is incorrect, the connecting plate 12 moves up to drive the limit teeth 13 and the limit grooves 112 to separate, so that the telescopic plate 111 can be retracted in the telescopic hole 7 to avoid further impact and ensure safety.
[0026] The left side of the mounting plate 10 is a horizontal structure, and the right side of the mounting plate 10 is an inclined structure. The left end of the buffer plate 171 is rotatably connected to the corner of the mounting plate 10. A positioning groove 18 is provided at the upper end of the left side of the mounting plate 10. The bottom of the positioning groove 18 is fixedly connected to the first pressure sensing module 19. A plurality of buffer grooves 172 are provided on the right side of the mounting plate 10. A clamping groove 173 is provided on the inner walls of both sides of the buffer groove 172. A detection plate 174 is inserted between the two clamping grooves 173. The hardness of the detection plate 174 increases from left to right. An infrared sensor is provided on the inner wall of the buffer groove 172. The infrared sensor is located below the detection plate 174. There is a certain angle between the buffer plate 171 and the right side of the mounting plate 10. A plurality of impact plates 175 are fixedly connected to the lower end of the buffer plate 171. The impact plates 175 correspond to the buffer grooves 172 one by one, and the buffer plate 171 is directly opposite to the anti-collision telescopic mechanism 11. After the impact column 114 hits the buffer plate 171, if the angle of the impact column 114 is correct, the impact column 114 will be guided to the left end of the mounting plate 10 by the buffer plate 171 and snapped into the positioning groove 18. The first pressure sensing module 19 in the positioning groove 18 senses the pressure and transmits the signal to control the operation of the second hydraulic rod 9. If the angle of the impact column 114 is incorrect, the pressure on the buffer plate 171 will be too large when it is impacted, and the impact plate 175 will squeeze the detection plate 174. The excessive pressure on the buffer plate 171 will cause the detection plate 174 to break, so that the impact plate 175 is detected by the infrared sensor, and the pushing operation is controlled to stop.
[0027] The first reinforcement block 261 and the second reinforcement block 263 are both L-shaped structures, and the side walls of the first reinforcement block 261 and the second reinforcement block 263 are both inclined structures. The first reinforcement block 261 and the second reinforcement block 263 form a rectangular structure. A plurality of plug-in grooves 262 are provided on the inclined surface of the first reinforcement block 261, and a plurality of plug-in blocks 264 are provided on the inclined surface of the second reinforcement block 263. A protrusion is fixedly connected to the side end of the second reinforcement block 263, and the protrusion is slidably connected to the connecting groove 20. The first reinforcement block 261 and the second reinforcement block 263 cooperate with each other to ensure the connection strength between the sliding shoe 4 and the support plate 8, and will not interfere with the upward movement of the guide beam frame 1 and the support plate 8.
[0028] The support plate 8 is rotatably connected to a limit plate 24, the left side of the limit plate 24 is a horizontal structure, the right side of the limit plate 24 is an arc structure, an auxiliary plate 25 is slidably connected between the upper end of the limit plate 24 and the support plate 8, and the auxiliary plate 25 is tilted. When the first hydraulic rod drives the guide beam frame 1 to move upward, the impact column 114 is clamped in the middle of the limit plate 24 and the mounting plate 10, thereby limiting and fixing the impact column 114, so that the sliding shoe 4 and the guide beam frame 1 are connected as a whole. When the sliding shoe 4 drives the guide beam frame 1 to move, it can ensure that the guide beam frame 1 and the sliding shoe 4 will not separate, thereby ensuring the normal implementation of the pushing operation.
[0029] A jacking construction process for a long-span steel structure bridge with an anti-collision structure comprises the following steps: Step 1: Before the guide beam frame 1 is pushed, the limiting teeth 13 are clamped into the limiting grooves 112 to limit and fix the telescopic plate 111, and the position height of the mounting plate 10 is controlled by controlling the second hydraulic rod 9 so that the buffer plate 171 faces the anti-collision impact mechanism; Step 2: During the top push, the impact column 114 hits the buffer plate 171, and the buffer plate 171 buffers the impact force and guides the impact column 114, so that the guide beam frame 1 is lifted, and the impact column 114 moves to the positioning groove 18, so that the first pressure sensing module 19 feels the pressure and transmits the signal to the second hydraulic rod 9, and the second hydraulic rod 9 drives the mounting plate 10 to move upward, and the impact column 114 squeezes the squeezing column, and the squeezing bead 21 squeezes the control bead 22, so that the second pressure sensing module 23 has pressure, so that the data is transmitted to the first hydraulic rod 5; Step 3: When the pushing angle is not appropriate, the impact column 114 hits the buffer plate 171, thereby driving the impact plate 175 to impact the detection plate 174, which will cause the force applied by the impact plate 175 to be greater than the force of the detection plate 174, thereby causing the detection plate 174 to break, causing the lower end of the impact plate 175 to be detected by the infrared sensor, controlling the pushing to stop, and avoiding subsequent collisions; Step 4: After the jacking is completed correctly, the first hydraulic rod 5 abuts against the upper end of the sliding shoe 4, thereby lifting the entire guide beam frame 1. At this time, the sliding shoe 4 slides along the track 3, driving the entire guide beam frame 1 to continue jacking until the jacking process is completed.
