Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, in particular to a stabilizing system for multi-span bridge construction. Background Art

[0002] As an important transportation facility connecting the land, multi-span bridges need to ensure the stability and safety of their structures during construction. In the construction process of multi-span bridges, sheet piles are usually used as a stabilizing device for the cement of the bridge pile foundation of the multi-span bridge located in the land to provide support for the foundation of the bridge piles of the multi-span bridge. During construction, multiple sheet piles are inserted into the bottom of the water to connect them into a double-layer rectangular enclosure. The interlayer is filled with sand and gravel for reinforcement to resist water pressure. The inner layer is pumped out with a water pump to form a bridge pile installation area to avoid the stability and life of the bridge piles in the water. The decrease provides a stable support for the foundation of the bridge piles of the multi-span bridge.

[0003] In the prior art, such as Chinese patent publication number CN117888526A, a stabilizing device for multi-span bridge construction is disclosed, including sheet piles, auxiliary sheet piles and hollow plates, and also including: a ground-breaking mechanism for breaking the ground in an N shape; an adjusting mechanism for adjusting power transmission; a telescopic mechanism for adjusting the height of the stabilizing device; a maintenance mechanism for performing spraying maintenance work during the construction of the multi-span bridge; by utilizing the ground-breaking mechanism to loosen and break the ground in an N shape when inserting the stabilizing device into the ground, the insertion efficiency of the stabilizing device is improved; then, with the cooperation of the water stored in the maintenance mechanism, the ground-breaking mechanism is transmitted to the telescopic mechanism through the adjusting mechanism, and the length of the stabilizing device is adjusted by the telescopic mechanism to improve the flexibility and adaptability of the stabilizing device; finally, the maintenance mechanism is used to spray water onto the pile foundation of the multi-span bridge construction for water spraying maintenance.

[0004] Although the above patent has multiple functions such as adjustment, ground breaking and maintenance, when constructing and reinforcing a multi-span bridge, in order to prevent the inner side of the sheet pile from affecting the structural strength due to water seepage, it is necessary to add a pumping structure. During the long-term use of the multi-span bridge, the pumping structure needs to be operated regularly to pump water. During the service life of the multi-span bridge of about one hundred years, the energy consumed by the pumping structure is huge, which is not conducive to energy conservation.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is used, as the bridge is used for a long time, water seepage will cause water accumulation in the area inside the sheet pile stabilization system for installing bridge piles. A power component is set to capture the water flow energy and wave energy of the water to drive the multi-blade water wheel to rotate, and the driving component is used to adjust the rotational forces in different directions of the multi-blade water wheel to rotational forces in the same direction. At this time, the accumulated water inside the inner sheet pile enclosure can be pumped out through the transmission component, the separation component and the pumping component.

[0018] 2.

The suction force generated at this time can absorb the accumulated water, silt, sand and gravel in the bridge pile area. When passing through the filter plate, the silt and accumulated water enter the pumping shell and are discharged, and the large sand and gravel remain under the filter plate. When the annular piston moves upward, the air pressure in the separation shell is restored, and the sand and gravel lose the suction and fall to the top of the partition plate. After squeezing open the third blocking plate under the action of the inclined surface and gravity and entering the second channel, it falls from the slag discharge port to the interlayer between the outer sheet pile and the inner sheet pile to supplement the hard filler and prevent the stability of the bridge from being affected by the loss of filler.

[0019] 3. When the present invention is used, when the accumulated water in the area where the inner sheet piles are used to install the bridge piles is pumped out and discharged from the drain outlet, the water will first enter the curved drain pipe and, under the action of pressure, will be squeezed out from the drain hole, which is close to the surface of the outer sheet pile. At this time, the squeezed water will be poured on the surface of the outer sheet pile to wet the outer sheet pile, thereby maintaining the surface of the outer sheet pile.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described 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 creative work are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1-Figure 10As shown, the present invention provides a technical solution: a stabilization system for multi-span bridge construction, comprising an inner sheet pile 1 and an outer sheet pile 11, a pumping assembly 2 is arranged near the top of the front surface of the outer sheet pile 11, a separation assembly 3 is arranged near the top of the rear surface of the outer sheet pile 11, a transmission assembly 4 is arranged at the bottom of the pumping assembly 2, a driving assembly 6 is arranged at the bottom of the transmission assembly 4, a power assembly 5 is arranged at the front side of the driving assembly 6, the pumping assembly 2 cooperates with the separation assembly 3 to extract the water accumulated at the rear side of the outer sheet pile 11, and comprises a pumping shell 201, a separation assembly 3 is used to separate solid matter and fluid impurities, including a separation shell 301, a transmission component 4 including a connection shell 401 and a drain pipe 404, a power component 5 including a four-claw frame 501, a plurality of floating plates 502 are fixedly connected to the outer surface of the four-claw frame 501 near the middle position, two mounting plates 503 are fixedly connected to the top of the four-claw frame 501, a multi-blade water wheel 504 is rotatably connected between the outer surfaces of the two mounting plates 503, and a driving component 6 is used to convert the different direction rotation force of the multi-blade water wheel 504 into the same direction rotation force, and includes a first ratchet gear 601.

[0024] The rear surface of the first ratchet gear 601 is rotatably connected to a cover plate 602, and the front surface of the cover plate 602 is fixedly connected to a rotating ring 607 near the edge. The inner surface wall of the rotating ring 607 is provided with a plurality of inner grooves 603 at equal intervals, and the inner part of the inner groove 603 is rotatably connected to an inner spring plate 605, which is elastically connected to the inner groove 603 through an arc spring and is inclined. The inner spring plate 605 is initially in a one-way meshing state with the first ratchet gear 601, and the first ratchet gear 601 is freely rotatably connected to the cover plate 602 through a shaft and a bearing. The rotating ring 607 is located on the outside of the first ratchet gear 601, and the outer spring plate 606 and the inner spring plate 605 are connected to the inner groove 603 and the outer groove 604 through a rotating pin and an arc spring. Fig. 9 , the outer spring plate 606 and the inner spring plate 605 are both in the initial state, and their maximum rotation angle is limited by the length of the arc spring. When the first ratchet gear 601 rotates clockwise, the inclined surface of the ratchet teeth on the surface will be squeezed with the inclined surface of the inner spring plate 605, so that the inner spring plate 605 squeezes the arc spring and contracts to enter the inner groove 603, and will not drive the rotating ring 607 to rotate. When the first ratchet gear 601 rotates counterclockwise, the straight surface of the ratchet teeth on the surface will form an extrusion force on the inclined inner spring plate 605, thereby pushing the rotating ring 607 to rotate counterclockwise.

[0025] The front surface of the first ratchet gear 601 is fixedly connected to the second rotating shaft 611, the rear end of the second rotating shaft 611 rotates and passes through the outer surface of one of the mounting plates 503, and the front end of the second rotating shaft 611 is fixedly connected to the center of the rear surface of the multi-blade water wheel 504, the outer surface of the second rotating shaft 611 is fixedly connected to the first pulley 608 near the middle position, the outer surface of the first pulley 608 is sleeved with a transmission belt 610, and the inner surface wall of the transmission belt 610 is sleeved with a second pulley 609 near the bottom, the outer surface of the second pulley 609 is fixedly connected to the third rotating shaft 612, the front end of the third rotating shaft 612 is rotatably connected to the rear surface of one of the mounting plates 503, the second rotating shaft 611 is used to connect the first ratchet gear 601, the first pulley 608 and the multi-blade water wheel 504, when the multi-blade water wheel 504 is actuated by the four claws The frame 501 and the floating plate 502 will float on the water surface, and about one-third of the bottom of the multi-blade water wheel 504 is submerged under the water surface. When water flows, the water flow energy generated by the water flow will impact the multi-blade water wheel 504. When waves are generated, the water surface will generate wave energy to impact the multi-blade water wheel 504. Therefore, the multi-blade water wheel 504 floating on the water surface will be in a rotating state when the water fluctuates, and the first pulley 608 and the first ratchet gear 601 will be driven to rotate through the second rotating shaft 611. When the first pulley 608 rotates, it will synchronously drive the third rotating shaft 612 to rotate through the transmission belt 610. When the third rotating shaft 612 rotates, it will drive the second pulley 609 to rotate synchronously in the same direction. Therefore, when the multi-blade water wheel 504 rotates under the action of water flow energy and wave energy, it will drive the first ratchet gear 601 and the second ratchet gear 613 to rotate synchronously.

[0026] The rear end of the third rotating shaft 612 is fixedly connected to the second ratchet gear 613. The outer surface of the rotating ring 607 is provided with a plurality of outer grooves 604 at equal intervals. The inner part of the outer groove 604 is rotatably connected to the outer spring plate 606. The outer spring plate 606 is elastically connected to the outer groove 604 through an arc spring and the outer spring plate 606 is inclined. In the initial state, the outer spring plate 606 is in a one-way meshing state with the second ratchet gear 613. The ratchet teeth on the surfaces of the second ratchet gear 613 and the first ratchet gear 601 face in opposite directions. Fig. 9 When the first ratchet gear 601 and the second ratchet gear 613 rotate clockwise, the first ratchet gear 601 will not generate thrust on the rotating ring 607, but the ratchet teeth on the surface of the second ratchet gear 613 will confront the outer spring plate 606, thereby pushing the rotating ring 607 to rotate counterclockwise. When the first ratchet gear 601 rotates counterclockwise, it will push the rotating ring 607 to rotate counterclockwise, and at this time the second ratchet gear 613 will squeeze the outer spring plate 606 into the outer groove 604, and will not affect the rotating ring 607. Therefore, when the multi-blade water wheel 504 rotates in any direction, it will drive the rotating ring 607 to rotate counterclockwise.

[0027] The top of the connecting shell 401 is fixedly connected to the bottom of the pumping shell 201, and a reciprocating screw rod 402 is rotatably connected between the inner top and inner bottom of the connecting shell 401. The bottom end of the reciprocating screw rod 402 is fixedly connected to a sleeve 406, and the bottom end of the sleeve 406 rotates through the inner bottom of the connecting shell 401 and extends downward. A plug rod 407 is slidably inserted between the sleeve 406 and the inner surface wall of the reciprocating screw rod 402, and an L-shaped connecting frame 408 is installed on the outer surface of the plug rod 407 near the bottom through a bearing, and the front surface of the connecting frame 408 is rotatably penetrated and connected with a first rotating shaft 411, and the rear end of the first rotating shaft 411 is fixedly connected to a second bevel gear 410, and the bottom end of the plug rod 407 is fixedly connected to a first bevel gear 409, and the first bevel gear 409 and the second bevel gear 410 are meshed and connected. The front end of the first rotating shaft 411 It is fixedly connected to the center of the rear surface of the cover plate 602, and the outer surface of the reciprocating screw rod 402 is threadedly connected to the reciprocating block 403. When the rotating ring 607 rotates, it will drive the second bevel gear 410 to rotate synchronously, and cooperate with the first bevel gear 409 to drive the plug rod 407 to rotate continuously in one direction. The plug rod 407 is inserted into the plug sleeve 406, and when it rotates, it will synchronously drive the plug sleeve 406 and the reciprocating screw rod 402 to rotate continuously. This design also allows the plug rod 407 and the power component 5 and the drive component 6 to slide up and down, so that the multi-blade water wheel 504 can drive the reciprocating screw rod 402 to rotate when it is located on the water surface at different heights. The reciprocating screw rod 402 and the reciprocating block 403 are connected by a crescent block. When the reciprocating screw rod 402 rotates continuously, it will drive the reciprocating block 403 to continuously reciprocate up and down.

[0028] The rear surfaces of the pumping shell 201 and the connecting shell 401 are fixedly connected to the front surface of the outer sheet pile 11. An annular piston 203 is slidably connected between the inner surface walls of the pumping shell 201. A through hole is provided at the center of the outer surface of the annular piston 203. The bottom of the annular piston 203 is fixedly connected to a connecting rod 206 near the four corners. The bottom end of the connecting rod 206 slides through the top of the connecting shell 401 and extends downward. The bottom end of the connecting rod 206 is fixedly connected to the top of the reciprocating block 403. A drain port 202 is provided near the bottom of the front surface of the pumping shell 201. The pumping shell 201 The top of the annular piston 203 is fixedly connected with a connecting channel 207, the bottom of the annular piston 203 is rotatably connected to the first blocking plate 204 near the front side, and the bottom of the annular piston 203 is fixedly connected to the limiting plate 205 near the rear side. When the reciprocating block 403 reciprocates up and down, the annular piston 203 inside the pumping shell 201 will be driven to reciprocate up and down through the connecting rod 206. When the water inside the inner sheet pile 1 reaches a certain depth, the bottom end of the pumping pipe 309 will be submerged under water. At this time, the pumping shell 201, the separation shell 301 and the pumping pipe 309 are generally in a closed state. When the annular piston 203 moves upward, the space between the annular piston 203 and the water pumping pipe 309 is in a closed state. The air pressure generated when the internal space is reduced will squeeze the first blocking plate 204 below the annular piston 203. When the annular piston 203 moves downward, the space between the annular piston 203 and the water pumping pipe 309 increases, and the air pressure decreases, so that the first blocking plate 204 is adsorbed on the bottom of the annular piston 203, and the second blocking plate 304 is expanded to expose the upper end of the water pumping pipe 309. As the annular piston 203 descends, the space below the water pumping shell 201 decreases, and the air pressure increases, thereby pumping the water below. The water is squeezed out from the drain port 202. At this time, the air pressure inside the pumping pipe 309 is reduced and suction is generated, which plays a role in pumping the accumulated water upward. With the reciprocating motion of the annular piston 203, the first blocking plate 204 and the second blocking plate 304 are continuously opened and closed, so that the accumulated water on the inside of the inner sheet pile 1 is pumped out through the pumping pipe 309 and discharged to the outside through the drain port 202. During the whole process, during the long service life of the multi-span bridge, only the water flow energy and wave energy generated by the water surface fluctuation can be used to complete the pumping operation of the water accumulated on the inside of the sheet pile, which not only ensures the stability of the sheet pile stabilization system, but also saves energy.

[0029] The front surface of the separation shell 301 and the rear surface of the outer sheet pile 11 are fixedly connected near the top, the top of the separation shell 301 and the bottom of the connecting channel 207 are fixedly connected, and the rear surface of the separation shell 301 is fixedly connected with a pumping pipe 309 near the bottom, and the bottom end of the pumping pipe 309 extends to the rear side of the inner sheet pile 1, and the rear inner wall of the separation shell 301 is rotatably connected with the second blocking plate 304 near the front end of the pumping pipe 309, and the separation shell 301 is connected to the internal space of the pumping shell 201 through the connecting channel 207, and the bottom end of the pumping pipe 309 is close to the ground of the enclosure area formed by the inner sheet piles 1, the width of the second blocking plate 304 is greater than the diameter of the pumping pipe 309, and a distance is retained between the front and rear sides of the second blocking plate 304 and the inner wall of the separation shell 301, so that the pumping pipe 309 can enter the first channel 307 from the front and rear sides of the second blocking plate 304 after pumping water, and then enter the pumping shell 201 through the connecting channel 207.

[0030] The use steps of the present invention are as follows: in the construction of a multi-span bridge, an outer sheet pile 11 is inserted into the soil at the bottom of the water at the reserved position of the bridge pile to form a rectangular enclosure, and then the outer sheet pile 11 is inserted into the bottom of the water to form an outer enclosure, and then a pumping device is used to pump out the water and silt in the inner area and the interlayer between the two layers of enclosures, and then the interlayer is filled with fillers such as stones and sand for reinforcement, and then a crossbeam is used to reinforce and support the top of the two layers of enclosures, so that the bridge piles supporting the multi-span bridge are separated from the water after erection, thereby ensuring the stability of the multi-span bridge. With the long-term use of the bridge, water seepage will cause water accumulation on the inside of the sheet piles, and the floating plate 502 in the device will float on the water surface outside the sheet pile enclosure under the action of buoyancy, and support the multi-blade water wheel 5 through the four-claw frame 501. 04, the lower third of the multi-blade water wheel 504 is submerged in water. With the flow of water and the generation of waves, the multi-blade water wheel 504 will rotate under the action of water flow energy and wave energy. When the multi-blade water wheel 504 rotates, it will drive the first pulley 608 and the first ratchet gear 601 to rotate through the second rotating shaft 611. At the same time, under the action of the second pulley 609 and the transmission belt 610, the second ratchet gear 613 will be in a synchronous and unidirectional rotation state with the first ratchet gear 601. When the first ratchet gear 601 and the second ratchet gear 613 rotate clockwise, the first ratchet gear 601 will not generate thrust on the rotating ring 607, but the ratchet teeth on the surface of the second ratchet gear 613 will confront the outer spring plate 606, thereby pushing the rotating ring 607 to rotate counterclockwise. When the first ratchet gear 601 rotates counterclockwise, it will push the rotating ring 607 to rotate counterclockwise by squeezing the inner spring plate 605, and at this time, the second ratchet gear 613 will squeeze the outer spring plate 606 to retract into the outer groove 604, and will not affect the rotating ring 607. Therefore, when the multi-blade water wheel 504 rotates in any direction, it will drive the rotating ring 607 to rotate counterclockwise. At this time, the rotating ring 607 will drive the plug rod 407 and the plug sleeve 406 to rotate continuously in one direction through the second bevel gear 410 and the first bevel gear 409, and drive the reciprocating screw rod 402 to rotate through the plug sleeve 406. When the reciprocating screw rod 402 rotates, the reciprocating block 403 will reciprocate up and down inside the connecting shell 401, and drive the pumping shell 20 through the connecting rod 206. The annular piston 203 inside reciprocates up and down. As the annular piston 203 moves upward, the space between the annular piston 203 and the water pumping pipe 309 is in a closed state. The air pressure generated when the internal space is reduced will squeeze the first blocking plate 204 below the annular piston 203. When the annular piston 203 moves downward, the space between the annular piston 203 and the water pumping pipe 309 increases, and the air pressure decreases, so that the first blocking plate 204 is adsorbed on the bottom of the annular piston 203, and the second blocking plate 304 is unfolded to expose the upper end of the water pumping pipe 309. As the annular piston 203 descends, the space below the water pumping shell 201 decreases, and the air pressure increases, so that the water below is squeezed out from the drain port 202. At this time, the air pressure inside the water pumping pipe 309 is reduced and suction is generated.It plays the role of pumping the accumulated water upward. With the reciprocating motion of the annular piston 203, the first blocking plate 204 and the second blocking plate 304 will be opened and closed continuously, so that the accumulated water inside the inner sheet pile 1 is pumped out through the pumping pipe 309 and discharged to the outside through the drain port 202. During the whole process, during the long service life of the multi-span bridge, only the water flow energy and wave energy generated by the fluctuation of the water surface can be used to complete the pumping operation of the accumulated water inside the sheet pile, which not only ensures the stability of the sheet pile stabilization system, but also saves energy.

[0031] Embodiment 2: Figure 5 , Figure 6 and Fig.10 As shown, the difference between the embodiment and the embodiment is that a filter plate 305 is installed at the top of the separation shell 301 at the inner side of the connecting channel 207, a partition plate 303 is fixedly connected between the inner surface walls on both sides of the separation shell 301, and the partition plate 303 is in an inverted V shape. A first channel 307 is arranged at the rear side of the partition plate 303 inside the separation shell 301, and a second channel 308 is arranged at the front side of the partition plate 303 inside the separation shell 301. The filter plate 305 is used to filter hard particle impurities such as sand and gravel in the water, and the partition plate 303 is used to separate the inside of the separation shell 301 into a first channel 307 and a second channel 308, and the top of the partition plate 303 is located below the filter plate 305 and is in an inclined state.

[0032] A slag discharge port 302 is provided at the bottom of the separation shell 301, and the slag discharge port 302 is located between the inner sheet pile 1 and the outer sheet pile 11. A third blocking plate 306 is rotatably connected to the rear side of the second channel 308 near the top. The outer surface of the third blocking plate 306 is in contact with the front surface of the partition plate 303. The slag discharge port 302 is used to discharge impurities such as hard sand and gravel in the separation shell 301 into the interlayer between the inner sheet pile 1 and the outer sheet pile 11, so as to supplement the filler. During the downward movement of the annular piston 203, the internal area of ​​the separation shell 301 and the pumping shell 201 increases, the air pressure decreases, the first blocking plate 204 is closed, and the second blocking plate 304 is opened. At this time, the third blocking plate 306 will also be in a closed state under the action of the air pressure.

[0033] In the use steps of the present invention, during the downward movement of the annular piston 203, the first blocking plate 204 is closed, the second blocking plate 304 is opened, and the third blocking plate 306 is also in a closed state under the action of air pressure, so that the first channel 307 and the second channel 308 are in a disconnected state. At this time, the suction force generated will absorb the accumulated water, silt, sand and other solid impurities in the bridge pile area at the same time. When passing through the filter plate 305, the silt and accumulated water will enter the pumping shell 201 through the filter plate 305 and be discharged normally, while the larger sand and gravel will be retained under the filter plate 305. As the annular piston 203 moves upward and the air pressure inside the separation shell 301 is restored, the sand and gravel lose suction and fall on the top of the partition plate 303. Since the top of the partition plate 303 is curved, the sand and gravel will squeeze the third blocking plate 306 under the action of gravity and enter the second channel 308 inside the separation shell 301, and finally fall from the slag discharge port 302 into the interlayer between the outer sheet pile 11 and the inner sheet pile 1, playing the role of supplementing the hard filler, which can effectively avoid the problem of the filler below the liquid surface in the sheet pile stabilization system being lost and affecting the stability of multi-span bridges.

[0034] Embodiment 3: Figure 1-Figure 3 and Figure 6 As shown, the difference between the embodiment and the drain pipe 404 is that the rear surface of the drain pipe 404 and the drain outlet 202 are fixedly connected by a connecting pipe, the drain pipe 404 is curved, and a plurality of drain holes 405 are provided on the outer surface of the drain pipe 404 near the rear side, the drain holes 405 are close to the front surface of the outer sheet pile 11, and the drain pipe 404 is used to discharge the water discharged from the drain outlet 202 from the drain holes 405.

[0035] The use steps of the present invention are as follows: when the accumulated water in the area where the inner sheet piles 1 are used to install the bridge piles is pumped out and discharged from the drain port 202, the water will first enter the curved drain pipe 404 and, under the action of pressure, will be squeezed out from the drain hole 405, and the drain hole 405 is close to the surface of the outer sheet pile 11. At this time, the squeezed water will be poured on the surface of the outer sheet pile 11 to wet the outer sheet pile 11, thereby maintaining the surface of the outer sheet pile 11.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
