Description

Technical Field

[0001] The present application relates to the technical field of bridge piers, and in particular to a bridge pier of an elevated bridge. Background Art

[0002] A viaduct refers to a bridge built above the ground to cross obstacles such as roads, railways, rivers, and urban buildings. The piers of the viaduct are the columns or piers that support the load-bearing structure and are usually made of concrete, steel, reinforced concrete and other materials.

[0003] An elevated bridge pier mentioned in an existing Chinese public patent (authorization announcement number: CN214301232U) can form a tie-arch structure together with a crossbeam through an inverted arch support, which can expand the support distance of the crossbeam and reduce the cantilever length of the crossbeam, thereby improving the stress state and reducing the structural height of the bottom of the beam. At the same time, the curved shape of the arch structure is more in line with the traditional Chinese aesthetics, increasing the landscape effect, and the appearance lines of the structure are achieved through the different structural dimensions of each part.

[0004] Most of the existing viaducts use single-column piers, which mainly rely on connection with the ground to maintain the stability of the bridge deck. However, due to the limited contact area between the pier and the ground, when vehicles pass frequently, gravity and load can only be transmitted to the ground through limited contact points, which may cause the pier support to be insufficiently stable and affect the stability of the pier. Utility Model Content

[0005] The purpose of the present application is to provide an elevated bridge pier in order to solve the problem that gravity and load can only be transferred to the ground through limited contact points, which may lead to insufficient stability of the bridge pier support.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0010] By adopting the above technical solution, the telescopic sleeve rod is pulled to slide inside the telescopic sleeve, driving the support seat to move downward and contact with the top of the foundation, thereby supporting the bridge pier.

[0011] Furthermore, a plurality of blocks are fixedly connected to the bottom of the support seat at equal intervals, the bottom of the block is configured to be conical, and the bottom of the block is in conflict with the foundation.

[0012] By adopting the above technical solution, the block can increase the friction between the support seat and the foundation, and reduce the risk of slippage and movement of the support seat under the action of external force.

[0013] Furthermore, the reinforcement member includes a reinforcement pile slidably connected to the inside of the support seat, the top end of the reinforcement pile penetrates the support seat and is fixedly connected to a striking block, and the bottom end of the reinforcement pile penetrates the foundation and is fixedly connected to a drill bit.

[0016] By adopting the above technical solution, the position of the telescopic sleeve can be fixed by bolts, so that it can be flexibly adjusted according to the use of the bridge and external conditions, thereby improving the adaptability to the pier support.

[0017] Furthermore, the support mechanism comprises a horizontal plate fixedly connected to both sides of the pier, the top of the horizontal plate is fixedly connected to a vertical plate, the top of the vertical plate is fixedly connected to an inclined plate, and the inclined plate is welded to the horizontal beam.

[0018] By adopting the above technical solution, an additional support point of the crossbeam is provided through the cross plate, so that the crossbeam is more stable during operation.

[0019] Furthermore, the inclined plate is arranged in an inclined shape, and the inclined plate is adapted to the shape of the crossbeam.

[0020] By adopting the above technical solution, the cross plate is set to be inclined by the inclined plate, so that the contact area between the cross plate and the cross beam becomes larger.

[0021] Furthermore, a diagonal brace is fixedly connected to the bottom of the transverse plate, the bottom end of the diagonal brace is welded to the bridge pier, and the diagonal brace is arranged in an inclined shape.

[0022] By adopting the above technical solution, a stable triangle is formed between the piers, the cross plates and the diagonal braces, thereby improving the resistance of the entire supporting mechanism.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, when supporting the bridge pier, the telescopic sleeve is pulled to slide inside the telescopic sleeve, driving the support seat to move downward and contact the top of the foundation, thereby supporting the bridge pier and dispersing the pressure to the pier and the support seat, thereby reducing the single-point load of the bridge, improving the overall bearing capacity, making the bridge pier more stable when under pressure, and ensuring the safe operation of the viaduct.

[0032] The following is combined with Figure 1-4This application is described in further detail.

[0033] An embodiment of the present application discloses a pier of an elevated bridge.

[0034] Reference Figure 1 and Figure 2 A viaduct bridge pier 1 comprises a pier 1, a foundation 2 is fixedly connected to the bottom of the pier 1, a buried pile 3 is fixedly connected to the bottom of the foundation 2, a cross beam 4 is fixedly connected to the top of the pier 1, connecting blocks 5 are fixedly connected to the top two sides of the cross beam 4, a supporting mechanism is arranged on the outer surface of the pier 1, and supporting mechanisms are arranged on both sides of the pier 1.

[0035] When constructing an elevated bridge, first use a crane to drive the buried piles 3 into the ground, then weld the foundation 2 to the top of the buried piles 3, then weld the pier 1 to the top of the foundation 2, and then check and correct the verticality and horizontality of the pier 1. Then weld the crossbeam 4 to the top of the pier 1 to ensure that it can bear and balance the weight of the bridge deck and fix it to the pier 1. Finally, install the elevated bridge through the connecting blocks 5 on both sides of the top of the crossbeam 4, thereby completing the construction of the elevated bridge. The support mechanism can improve the anti-overturning ability of the pier 1, thereby improving the stability of the pier 1, and the support mechanism can expand the supporting distance of the crossbeam 4, thereby improving the stress state.

[0036] Reference Figure 3 and Figure 4 The supporting mechanism includes a fixed block 6 sleeved on the outer surface of the pier 1, and the four sides of the fixed block 6 are fixedly connected with a rotating seat 7 at equal intervals. The inside of the rotating seat 7 is rotatably connected with a telescopic sleeve 8, and the inside of the telescopic sleeve 8 is slidably connected with a telescopic sleeve rod 9. The bottom of the telescopic sleeve rod 9 is rotatably connected with a support seat 10, and the bottom of the support seat 10 overlaps with the foundation 2. A reinforcement is arranged inside the support seat 10.

[0037] The bottom of the support seat 10 is fixedly connected with a plurality of blocks 11 at equal intervals. The bottom of the block 11 is set to be conical, and the bottom of the block 11 is in conflict with the foundation 2.

[0038] In addition, the reinforcement member includes a reinforcement pile 14 slidably connected to the inside of the support seat 10, the top end of the reinforcement pile 14 passes through the support seat 10 and is fixedly connected to a striking block 15, and the bottom end of the reinforcement pile 14 passes through the foundation 2 and is fixedly connected to a drill bit 16.

[0039] When supporting the bridge pier 1, the telescopic sleeve 8 is rotated so that the telescopic sleeve 8 rotates inside the rotating seat 7. At the same time, when the telescopic sleeve 8 rotates, the telescopic sleeve rod 9 is driven to rotate. After rotating to a suitable angle, the telescopic sleeve rod 9 is then pulled to slide inside the telescopic sleeve 8, driving the support seat 10 to move downward and contact the top of the foundation 2, thereby supporting the bridge pier 1, so that the pressure is dispersed to the bridge pier 1 and the support seat 10, thereby reducing the single-point load of the bridge, improving the overall bearing capacity, making the bridge pier 1 more stable when subjected to pressure, and ensuring the safe operation of the viaduct. When the support seat 10 is overlapped with the foundation 2, a plurality of blocks 11 at the bottom of the support seat 10 can increase the support seat 10 and the foundation 2. The friction of the foundation 2, the block 11 is made of rubber, and their friction can effectively reduce the risk of slippage and movement of the support seat 10 under the action of external force. When the support seat 10 conflicts with the foundation 2, a reinforcement pile 14 slides through the inside of the support seat 10. At this time, the staff uses a tool to apply pressure to the striking block 15, so that the striking block 15 moves downward. The striking block 15 moves downward and drives the reinforcement pile 14 to move downward, so that the reinforcement pile 14 goes deep into the ground. The connection between the support seat 10 and the foundation 2 can be strengthened by the reinforcement pile 14, so that the bearing capacity of the pier 1 is improved. When the reinforcement pile 14 is driven into the ground, a drill bit 16 is fixed at the bottom of the reinforcement pile 14, so that the reinforcement pile 14 is easier to drive.

[0040] Reference Figure 1 ,, Figure 2 and Figure 3 A through hole is provided on one side of the telescopic sleeve 8, a bolt 12 is provided inside the through hole, the bolt 12 is slidably arranged with the through hole, and a plurality of threaded holes 13 are equidistantly provided on one side of the telescopic sleeve rod 9, and the bolt 12 is threadedly connected with the threaded hole 13.

[0041] When the telescopic sleeve 9 moves to a suitable position inside the telescopic sleeve 8, a bolt 12 is placed inside the through hole, and then threadedly connected with the bolt 12 through the threaded hole 13, so that the bolt 12 enters the threaded hole 13, thereby fixing the position of the telescopic sleeve 9. The telescopic sleeve 9 is slidably connected with the telescopic sleeve 8, which can be flexibly adjusted according to the use of the bridge and external conditions, thereby improving the adaptability to the support of the pier 1.

[0042] Reference Figure 1 and Figure 2 The supporting mechanism includes a horizontal plate 17 fixedly connected to both sides of the pier 1, a vertical plate 18 fixedly connected to the top of the horizontal plate 17, an inclined plate 19 fixedly connected to the top of the vertical plate 18, and the inclined plate 19 is welded to the supporting plate.

[0043] The inclined plate 19 is arranged to be inclined, and the shape of the inclined plate 19 is adapted to the shape of the support plate.

[0044] In addition, a diagonal brace 20 is fixedly connected to the bottom of the transverse plate 17, the bottom end of the diagonal brace 20 is welded to the bridge pier 1, and the diagonal brace 20 is arranged in an inclined shape.

[0045] When supporting the cross beam 4, the cross beam 4 transfers the pressure to the inclined plate 19, the inclined plate 19 transfers the pressure to the vertical plate 18, the vertical plate 18 transfers the pressure to the cross plate 17, and the cross plate 17 finally transfers the pressure to the pier 1. The cross plate 17 provides an additional support point for the cross beam 4, making the cross beam 4 more stable during operation. The cross plate 17 is set to an inclined shape by the inclined plate 19, so that the contact area between the cross plate 17 and the cross beam 4 becomes larger, providing stronger supporting force. By fixing the diagonal brace 20 at the bottom of the cross plate 17, a stable triangle is formed between the pier 1, the cross plate 17 and the diagonal brace 20, thereby improving the resistance of the entire supporting mechanism.

[0046] Working principle: Use a crane to drive the piles 3 into the ground, then weld the foundation 2 to the top of the piles 3, then weld the pier 1 on the top of the foundation 2, then weld the crossbeam 4 on the top of the pier 1, and finally install the viaduct through the connecting blocks 5 on both sides of the top of the crossbeam 4, thereby completing the construction of the viaduct, and rotating the telescopic sleeve 8 so that the telescopic sleeve 8 rotates inside the rotating seat 7. At the same time, when the telescopic sleeve 8 rotates, it will drive the telescopic sleeve rod 9 to rotate. When it rotates to a suitable angle, then pull the telescopic sleeve rod 9 to slide inside the telescopic sleeve 8, driving the support seat 10 to move downward and contact the top of the foundation 2, thereby supporting the pier 1, so that the pressure is dispersed to the pier 1 and the support seat 10, thereby reducing the single point load of the bridge.

[0047] When supporting the cross beam 4, the cross beam 4 transfers the pressure to the inclined plate 19, the inclined plate 19 transfers the pressure to the vertical plate 18, the vertical plate 18 transfers the pressure to the cross plate 17, and the cross plate 17 finally transfers the pressure to the pier 1. The cross plate 17 provides an additional support point for the cross beam 4, making the cross beam 4 more stable during operation. The cross plate 17 is set to an inclined shape by the inclined plate 19, so that the contact area between the cross plate 17 and the cross beam 4 becomes larger, providing stronger supporting force. By fixing the diagonal brace 20 at the bottom of the cross plate 17, a stable triangle is formed between the pier 1, the cross plate 17 and the diagonal brace 20, thereby improving the resistance of the entire supporting mechanism.
