Description

Technical Field

[0001] The present invention relates to the technical field of bridge and tunnel engineering, and in particular to a bridge and tunnel engineering reinforced pier support. Background Art

[0002] A pier support is an architectural concept that refers to the columnar structure that supports a bridge. Together with the foundation, it forms the two main structures that support the bridge. Piers are generally square, but they can also be rectangular or other shapes. In addition to supporting the bridge, piers must also block the flow of water. Therefore, there must be a certain distance between each pier, making piers a necessity for bridges. Existing pier supports use steel bars to secure the piers to the bridge supports, but this fixation is poor. When more cars pass on one side of the bridge, the bridge will apply higher pressure to one side of the bridge supports, potentially causing a break between the bridge supports and the pier support, leading to major safety incidents. Summary of the Invention

[0003] In response to the shortcomings of the existing technology, the present invention provides a bridge pier support for strengthening bridge and tunnel projects, which solves the problem that the pier support in the existing technology has poor fixing effect between the supporting pier and the bridge bracket used to support the bridge. When there are many cars passing on one side of the bridge, the bridge bracket and the pier support are likely to break, leading to major safety accidents.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A bridge pier support for strengthening a bridge tunnel project comprises a supporting pier, wherein a support frame for supporting the bridge is fixedly mounted on the upper end of the supporting pier, and a base is fixedly mounted on the lower end of the supporting pier, wherein a plurality of steel bar holes for connecting with steel bars are formed on the lower surface of the base;

[0006] Reinforcement components for reinforcing the support frame are respectively provided on both sides of the support frame and the supporting pier.

[0007] Preferably, the reinforcement assembly includes a mounting seat, the mounting seat is fixedly mounted on a corresponding side of the supporting pier, and a first mounting block is movably provided on the upper surface of the supporting pier;

[0008] A second mounting block is fixedly installed on both sides of the support frame, and a limiting column is fixedly installed on the opposite side of the first mounting block and the second mounting block. The two limiting columns are both provided with a rotating sleeve, and the two rotating sleeve bodies are both fixedly installed with a connecting ring. The two connecting ring bodies are both movably provided with a rope hook, and a connecting rope is fixedly installed on the opposite end of the two rope hooks.

[0009] Preferably, a sliding groove is provided on the upper surfaces of the two mounting seats, a slider is slidably provided in the two sliding grooves, and the upper surfaces of the two sliders are respectively fixedly connected to the corresponding first mounting blocks.

[0010] Preferably, the connecting rope is a steel wire rope.

[0011] Preferably, a screw rod is rotatably installed between the two inner walls of the two slide grooves, and the two sliders are respectively threaded on one side of the corresponding screw rod body. The screw rods pass through the corresponding mounting seats at one end away from each other and are fixedly installed with a hexagonal block.

[0012] Preferably, support plates are fixedly mounted on the upper surfaces of the two first mounting blocks, movable plates are movably provided on the upper surfaces of the two support plates, and top plates are fixedly mounted on one side of the upper surfaces of the two movable plates via right-angle brackets.

[0013] Preferably, the surfaces on the opposite sides of the two top plates are both configured as inclined surfaces.

[0014] Preferably, a movable groove is provided on the upper surfaces of the two support plates, and a movable block is slidably arranged in the two movable grooves, and the upper surfaces of the two movable blocks are fixedly connected to the corresponding support plates respectively.

[0015] Preferably, a positioning rod is fixedly installed between the two inner walls of the two movable grooves, the two movable blocks are respectively slidably arranged on one side of the positioning rod body, and the other side of the two positioning rod bodies is sleeved with an elastic member that can be compressed and reset.

[0016] Preferably, the elastic member is a spring.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The staff buried the base into the foundation and connected the steel bar holes on the lower surface of the base with the embedded steel bars in the foundation. Then the staff used a crane to place the bridge on the support frame. After the bridge was placed on the support frame, the reinforcement components cooperated to greatly enhance the fixing effect between the support frame and the supporting piers, avoiding the occurrence of fractures between the bridge support and the pier support when there are many cars passing on one side of the bridge. This not only effectively reinforced the bridge, but also avoided the occurrence of major accidents.

[0019] 2. The staff engages the output end of the rotating device with the hexagonal block, and then starts the rotating device to make the output end drive the hexagonal block and the screw rod to rotate. The rotating screw rod drives the slider and the first mounting block to move along the slide groove direction by screwing in the thread, so that the staff can control the tension or relaxation of the wire rope. When the wire rope is tightened, the support frame can be strengthened and fixed. When the wire rope is loose, it is convenient for the staff to remove the rope hook from the connecting ring, which is convenient for the staff to quickly disassemble and assemble the wire rope.

[0020] 3. When the slider moves along the direction of the slide groove, the inclined surface of the top plate can push the inclined surface of the support frame. The spring is compressed and gives the top plate a reverse elastic force, so that the top plate can fit tightly with the inclined surface of the support frame, thereby enhancing the tightening effect and further enhancing the fixing effect between the support frame and the supporting pier.

[0028] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments 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 making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1-6 As shown, a bridge tunnel engineering reinforcement pier support includes a supporting pier 1, a supporting frame 2 for supporting the bridge is fixedly installed on the upper end of the supporting pier 1, a base 3 is fixedly installed on the lower end of the supporting pier 1, and a plurality of steel bar holes for connecting with steel bars are opened on the lower surface of the base 3;

[0030] Reinforcement components 4 for reinforcing the support frame 2 are respectively provided on both sides of the support frame 2 and the supporting pier 1 .

[0031] Through the above technical solution, when in use, the staff will bury the base 3 into the foundation, and connect the steel bar holes set on the lower surface of the base 3 with the embedded steel bars in the foundation. Then the staff will use a crane to place the bridge on the support frame 2. After the bridge is placed on the support frame 2, with the cooperation of the reinforcement component 4, the fixing effect between the support frame 2 and the supporting pier 1 is greatly enhanced, avoiding the occurrence of fractures between the bridge support and the pier support when there are many cars passing through one side of the bridge. Not only is the bridge effectively reinforced, but also the occurrence of major accidents is avoided.

[0032] like Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 As shown, in this embodiment, the reinforcement assembly 4 includes a mounting seat 401, which is fixedly mounted on a corresponding side of the supporting pier 1, and a first mounting block 402 is movably provided on the upper surface of the supporting pier 1;

[0033] A second mounting block 403 is fixedly installed on both sides of the support frame 2, and a limiting column is fixedly installed on the opposite side of the first mounting block 402 and the second mounting block 403. The two limiting columns are both provided with a rotating sleeve 404, and the two rotating sleeves 404 are both fixedly installed with a connecting ring 405. The two connecting rings 405 are both movably provided with a rope hook 406, and the two rope hooks 406 are jointly fixedly installed with a connecting rope 407 at one opposite end.

[0034] The connecting rope 407 is a steel wire rope.

[0035] When the wire rope is taut, the support frame 2 applies a larger oblique pulling force to the second mounting block 403 through the wire rope. Compared with the steel bar connection method, the fixing effect between the support frame 2 and the supporting pier 1 is greatly enhanced, avoiding the occurrence of fracture between the bridge support and the pier support when there are many cars passing on one side of the bridge. It not only effectively reinforces the bridge, but also avoids the occurrence of major accidents.

[0036] As shown Figure 3 、 5 As shown, it should be noted that, the upper surfaces of the two mounting seats 401 are both provided with a slide groove 4011, and the two slide grooves 4011 are both slidably provided with a slider 4012, and the upper surfaces of the two sliders 4012 are respectively fixedly connected to the corresponding first mounting blocks 402.

[0037] A screw rod 4013 is rotatably installed between the inner walls of the two slide grooves 4011. Two sliders 4012 are respectively threadedly set on one side of the corresponding screw rod 4013. The ends of the screw rods 4013 away from each other pass through the corresponding mounting seats 401 and are fixedly installed with hexagonal blocks 4014.

[0038] The staff engages the output end of the rotating device with the hexagonal block 4014, and then starts the rotating device, so that the output end drives the hexagonal block 4014 and the screw rod 4013 to rotate, and the rotating screw rod 4013 drives the slider 4012 and the first mounting block 402 to move along the slide groove 4011 by screwing in the thread, so that the staff can control the tension or relaxation of the wire rope. When the wire rope is tightened, the support frame 2 can be strengthened and fixed. When the wire rope is loose, the staff can easily remove the rope hook 406 from the connecting ring 405, which is convenient for the staff to quickly disassemble and assemble the wire rope.

[0039] like Figure 1 、 Figure 5 、 Figure 6 As shown, in the specific setting, the upper surfaces of the two first mounting blocks 402 are fixedly mounted with support plates 5, the upper surfaces of the two support plates 5 are movably mounted with movable plates 501, and one side of the upper surface of the two movable plates 501 is fixedly mounted with a top plate 503 through a right-angle bracket 502.

[0040] The surfaces of the two top plates 503 on opposite sides are both configured as inclined surfaces.

[0041] A positioning rod 506 is fixedly installed between the two inner walls of the two moving grooves 504, and the two moving blocks 505 are slidably set on one side of the rod body of the positioning rod 506. The other side of the rod body of the two positioning rods 506 is sleeved with an elastic member 507 that can be compressed and reset.

[0042] The elastic member 507 is a spring.

[0043] When the slider 4012 moves along the direction of the slide groove 4011, the inclined surface of the top plate 503 can push the inclined surface of the support frame 2. The spring is compressed and gives the top plate 503 a reverse elastic force, so that the top plate 503 can fit tightly with the inclined surface of the support frame 2, thereby enhancing the tightening effect and further enhancing the fixing effect between the support frame 2 and the supporting pier 1.

[0044] When in use, first, the staff buries the base 3 into the foundation, and connects the steel bar holes set on the lower surface of the base 3 with the embedded steel bars in the foundation. Then the staff uses a crane to place the bridge on the support frame 2. After the bridge is placed on the support frame 2, with the cooperation of the reinforcement component 4, the fixing effect between the support frame 2 and the supporting pier 1 is greatly enhanced, avoiding the occurrence of fractures between the bridge support and the pier support when there are many cars passing through one side of the bridge. Not only is the bridge effectively reinforced, but also major accidents are avoided.

[0045] The above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to enumerate all the implementation methods here. Any obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
