Description
Technical Field
[0001] This application relates to the technical field of bridge construction, and in particular to equipment and methods for bridge abutment construction. Background Technology
[0002] A pile cap is a reinforced concrete platform erected on top of a pile foundation to connect the tops of the piles, in order to bear and distribute the loads transmitted from the pier. Pile caps include high-pile pile caps and low-pile pile caps. High-pile pile caps are generally used in ports, docks, marine engineering, and bridge engineering, while low-pile pile caps are generally used in industrial and civil buildings.
[0003] In related technologies, when operators construct bridge abutments, they first pour a concrete foundation layer on the construction site, then tie the reinforcing bars, arrange the concrete formwork according to the abutment dimensions, and finally pour the concrete.
[0004] Regarding the aforementioned technologies, the inventors believe that the height of a typical foundation is relatively large, making it difficult for operators to effectively vibrate the concrete at the bottom of the foundation. This results in the concrete at the bottom of the foundation not being compacted properly, which can easily affect the quality of the foundation. Summary of the Invention
[0005] In order to improve the quality of bridge pier caps, this application provides bridge pier cap construction equipment and construction methods.
[0006] The bridge pier construction equipment provided in this application adopts the following technical solution:
[0007] Bridge abutment construction equipment includes a template set on a foundation for pouring the abutment. The bottom of the template is provided with multiple mixing rods. Each mixing rod includes a fixed section fixedly connected to the template, a rotating section rotatably installed on the template, and a mixing section for mixing concrete set between the fixed section and the rotating section. The mixing section is rotatably connected to the fixed section and fixedly connected to the rotating section. The template is provided with a rotating component for driving the rotating section to rotate.
[0008] By adopting the above technical solution, when the operator pours concrete into the formwork, the operator starts the rotating component. The rotating component causes the rotating section to rotate, which in turn drives the mixing rod to rotate. The rotation of the mixing rod ensures that the concrete at the bottom of the foundation is fully compacted, which is beneficial to improving the quality of the concrete.
[0009] Preferably, each of the adjacent rotating segments is fixedly fitted with a rotating pulley, and a belt is wound between the adjacent rotating pulleys. The rotating assembly includes a rotating motor mounted on the template, a driving gear fixedly connected to the rotating motor, and a driven gear fixedly fitted on the rotating segment. The driving gear and the driven gear mesh with each other.
[0010] By adopting the above technical solution, the operator starts the rotating motor, the output shaft of the rotating motor rotates and drives the driving gear to rotate, which in turn drives the driven gear to rotate, thus making the rotating section rotate. The rotating section rotates synchronously through the cooperation of the rotating pulley and belt, thereby enabling all the rotating sections to perform the concrete mixing operation synchronously, which is beneficial to improving the compactness of the concrete.
[0011] Preferably, the stirring rods are arranged sequentially along the length of the template, and each stirring rod is internally fitted with a circulating water pipe. One end of the circulating water pipe is fixedly connected to the fixed section, and a water guide is installed at the end of the circulating water pipe extending into the stirring section. A water supply pipe for communicating with the stirring section is installed on the fixed section. A connecting pipe for communicating with the water supply pipe on the end of the circulating water pipe away from the water guide is provided. A water storage tank for storing cooling water is provided on the pad layer, and a water pump for conveying cooling water is provided on the water storage tank. The outlet of the water pump is connected to the water supply pipe located at one end of the template, and the connecting pipe located at the other end of the template is connected to the water storage tank.
[0012] By adopting the above technical solution, after the concrete is poured, the operator starts the water pump. The water pump causes the cooling water in the water storage tank to enter the mixing section through the water delivery pipe from the water pump outlet. The cooling water in the mixing section can enter the circulating water pipe through the water guide. The cooling water in the circulating water pipe then enters the mixing section of the adjacent mixing rod through the connecting pipe and the water delivery pipe on the adjacent mixing rod. Finally, the cooling water in the last circulating water pipe enters the water storage tank directly through the connecting pipe, thereby realizing the circulation of cooling water. The flow of cooling water in the concrete can remove a large amount of heat from the concrete, thereby reducing the impact of thermal expansion and contraction of the concrete, reducing the possibility of cracking inside the foundation, and further improving the construction quality of the foundation.
[0013] Preferably, a stirring ring is fixedly connected to the stirring section, and an annular cavity for communicating with the stirring section is opened in the stirring ring; an atomizing nozzle is installed on the template, and a liquid inlet pipe is connected to the atomizing nozzle. The liquid inlet pipe passes through the template and the fixed section in sequence and is connected to the circulating water pipe.
[0014] By adopting the above technical solutions, the setting of the mixing ring and the annular cavity helps to expand the heat absorption range of the cooling water, and the setting of the atomizing nozzles makes it convenient for operators to use cooling water to cure the surface of the concrete, which helps to improve the curing effect of the concrete.
[0015] Preferably, the template includes two first side plates arranged opposite each other and a second side plate arranged on both sides of the first side plates. A positioning post is fixedly connected to the bottom of the first side plate. A positioning groove for inserting and cooperating with the positioning post is provided on the pad. An abutment block is slidably arranged on the bottom surface of the first side plate. A limiting groove for sliding and cooperating with the abutment block is provided on the pad. A driving component for driving the abutment block to move is provided on the first side plate.
[0016] By adopting the above technical solution, the positioning post and positioning groove are conducive to pre-positioning the positions of the two first side plates. When the operator inserts the positioning post on the first side plate into the positioning groove, the operator can move the abutment block through the driving component until the abutment block abuts against the inner wall of the limiting groove. The abutment block and the limiting groove cooperate to further fix the first side plate, thereby improving the stability of the template.
[0017] Preferably, the drive assembly includes a first bidirectional lead screw rotatably mounted in the first side plate, a worm gear fixedly sleeved on the first bidirectional lead screw, and a worm passing through the first side plate. The first bidirectional lead screw passes through the abutment block, the abutment block is threadedly engaged with the first bidirectional lead screw, and the worm and the worm gear mesh with each other. A handwheel is provided at the end of the worm away from the worm gear.
[0018] By adopting the above technical solution, the operator rotates the handwheel, which drives the worm gear to rotate, which in turn drives the worm wheel to rotate, which in turn drives the first bidirectional lead screw to rotate, thereby moving the abutment block and causing the abutment block to press against the inner wall of the limiting groove.
[0019] Preferably, rubber pads are fixedly connected to both sides of the first side plate, and an installation groove is provided on the second side plate for insertion and engagement with the first side plate. A locking block is slidably disposed on the first side plate, and a slot is provided on the inner side wall of the installation groove for sliding engagement with the locking block. A fixing component for fixing the locking block is provided in the second side plate, and a control component for driving the locking block to move is provided on the first side plate.
[0020] By adopting the above technical solution, after the operator fixes the position of the first side plate, the operator aligns the position of the locking block on the first side plate and slowly lowers the second side plate until the first side plate is inserted into the mounting groove and the locking block is inserted into the groove. The operator locks the position of the locking block through the fixing component, thereby strengthening the connection strength between the first side plate and the second side plate. The control component makes the locking block drive the second side plate to move, thereby making the rubber pad abut against the inner end face of the mounting groove, further improving the stability of the template.
[0021] Preferably, the fixing assembly includes a pull rod passing through the second side plate, a plug fixedly connected to the pull rod, and a spring sleeved on the pull rod. The inner side wall of the slot is provided with a sliding groove for sliding cooperation with the plug. One end of the spring is fixedly connected to the plug, and the other end of the spring is fixedly connected to the inner side wall of the sliding groove. The plug is provided with a slot for insertion cooperation with the plug. A fixing plate is provided at the end of the pull rod away from the plug. An inclined surface is provided at the end of the plug away from the fixing plate. An inclined surface is provided at the end of the plug near the plug, and the inclined surface of the plug matches the inclined surface of the plug.
[0022] By adopting the above technical solution, when the second side plate moves downward, the insert block and the locking block contact each other first. The locking block causes the insert block to enter the slide groove first through the inclined surface. At this time, the spring is in a compressed state. When the insert block is aligned with the slot on the locking block, the insert block is inserted into the slot under the elastic force of the spring, thereby locking the first side plate and strengthening the connection strength between the first side plate and the second side plate.
[0023] Preferably, the first side plate has an installation cavity. The control component includes a second bidirectional lead screw rotatably mounted on the inner wall of the installation cavity, a driving pulley fixedly sleeved on the first bidirectional lead screw, and a driven pulley fixedly sleeved on the second bidirectional lead screw. A synchronous belt is wound between the driving pulley and the driven pulley. Both ends of the second bidirectional lead screw are provided with movable seats. Each movable seat corresponds to a locking block. The movable seat is fixedly connected to the locking block. The movable seat is threadedly engaged with the second bidirectional lead screw. The inner wall of the installation cavity has a sliding groove for sliding engagement with the movable seat.
[0024] By adopting the above technical solution, when the operator turns the handwheel to make the first bidirectional lead screw rotate, the first bidirectional lead screw drives the driving pulley to rotate. The driving pulley causes the driven pulley and the second bidirectional lead screw to rotate synchronously through the synchronous belt. The rotation of the second lead screw drives the moving seat to rotate, and the rotation of the moving seat drives the locking block to move, ultimately causing the second side plate to move, thereby improving the stability of the template.
[0025] The construction method for bridge piers provided in this application adopts the following technical solution:
[0026] The construction method for bridge abutments includes the following steps:
[0027] S1. Construct a cushion layer on top of the pile foundation;
[0028] S2. Tie the foundation reinforcement;
[0029] S3. Install the first side plate and the second side plate, and combine the first side plate and the second side plate to form a template for pouring the foundation.
[0030] S4. Pour concrete, vibrate the top part of the concrete, and mix the bottom part of the concrete.
[0031] S5. Use cooling water to cool the interior of the concrete.
[0032] S6. The process of using atomizing nozzles to spray atomized water to cure the concrete surface;
[0033] S7. After the curing is completed, the template will be disassembled.
[0034] In summary, this application includes at least one of the following beneficial technical effects:
[0035] 1. When the operator pours concrete into the formwork, the operator starts the rotating component. The rotating component causes the rotating section to rotate, which in turn drives the mixing rod to rotate. The rotation of the mixing rod ensures that the concrete at the bottom of the foundation is fully compacted, which helps to improve the quality of the concrete.
[0036] 2. After the concrete is poured, the operator starts the water pump. The water pump causes the cooling water in the storage tank to enter the mixing section through the water delivery pipe from the pump outlet. The cooling water in the mixing section can enter the circulating water pipe through the water guide. The cooling water in the circulating water pipe then enters the mixing section of the adjacent mixing rod through the connecting pipe and the water delivery pipe on the adjacent mixing rod. Finally, the cooling water in the last circulating water pipe enters the storage tank directly through the connecting pipe, thus realizing the circulation of cooling water. The flow of cooling water in the concrete can remove a large amount of heat from the concrete, thereby reducing the impact of thermal expansion and contraction of the concrete, reducing the possibility of cracking inside the foundation, and further improving the construction quality of the foundation.
[0037] 3. After the operator fixes the position of the first side plate, the operator aligns the second side plate with the position of the locking block on the first side plate and slowly lowers it until the first side plate is inserted into the mounting groove and the locking block is inserted into the groove. The operator locks the position of the locking block through the fixing component, thereby strengthening the connection between the first and second side plates. The control component makes the locking block move the second side plate, thereby making the rubber pad abut against the inner end face of the mounting groove, further improving the stability of the template.

[0045] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0046] This application discloses bridge pier construction equipment in its embodiments. (Refer to...) Figure 1 The bridge abutment construction equipment includes a formwork 1 set on the subbase 3 and a mixing rod 2.
[0047] Reference Figure 2The template 1 includes a first side plate 11 and a second side plate 12. The first side plate 11 is rectangular and vertically arranged.

A limiting groove 32 is provided on the pad 3 for sliding and engaging with the abutment blocks 112.
[0049] Reference Figure 1 , Figure 2 A drive assembly 4 for moving the abutment block 112 is provided on the first side plate 11. The drive assembly 4 includes a first bidirectional lead screw 41, a worm gear 42, and a worm 43. The first bidirectional lead screw 41 is horizontally inserted into the first side plate 11 and is rotatably connected to the first side plate 11. One abutment block 112 is sleeved on one end of the first bidirectional lead screw 41, and the other abutment block 112 is sleeved on the other end of the first bidirectional lead screw 41. The first bidirectional lead screw 41 and the abutment block 112 are threadedly engaged.

[0050] Reference Figure 1 , Figure 2 The second side panel 12 includes a first panel 121 and a second panel 122 arranged opposite to each other. Both the first panel 121 and the second panel 122 are vertically arranged, and mounting grooves 123 are formed on the sides of the first panel 121 and the second panel 122 that are close to each other. The length direction of the mounting groove 123 is consistent with the height direction of the first panel 121, and the first side panel 121 slides against the inner wall of the mounting groove 123. Rubber pads 114 are fixedly connected to the two opposite sides of the first side panel 12, and the rubber pads 114 abut against the inner wall of the mounting groove 123.
[0051] Reference Figure 2 , Figure 3Two locking blocks 13 are spaced apart on a single first side plate 11. The locking blocks 13 slide with the first side plate 11, and both the first panel 121 and the second panel 122 have slots 124 for sliding with the locking blocks 13. Both the first panel 121 and the second panel 122 have fixing components 6 for fixing the locking blocks 13. The fixing components 6 include a pull rod 61, an insert 62, and a spring 63. The pull rod 61 passes through the inner wall of the slot 124, and the insert 62 is fixedly connected to the end of the pull rod 61 near the locking block 13. The inner wall of the locking block 13 has a sliding groove 125, and the insert 62 slides with the inner wall of the sliding groove 125. The end of the insert 62 away from the pull rod 61 has a slope, and the end of the locking block 13 near the insert 62 also has a slope, with the slopes of the insert 62 and the locking block 13 matching each other. A fixing plate 64 is provided at the end of the pull rod 61 away from the insert block 62, and the fixing plate 64 is fixedly connected to the pull rod 61. A spring 63 is sleeved on the pull rod 61, one end of the spring 63 is fixedly connected to the insert block 62, and the other end of the spring 63 is fixedly connected to the inner end face of the slide groove 125.
[0052] Reference Figure 2 , Figure 3 A control assembly 5 for driving the movement of the locking block 13 is provided on the first side plate 11. The control assembly 5 includes a second bidirectional lead screw 51, a driving pulley 52, and a driven pulley 53. A mounting cavity 54 is formed in the first side plate 11, and the cross-section of the mounting cavity 54 is rectangular. The second bidirectional lead screw 51 is horizontally disposed in the mounting cavity 54 and is rotatably connected to the inner wall of the mounting cavity 54. The driving pulley 52 is fixedly sleeved on the first bidirectional lead screw 41, and the driven pulley 53 is fixedly sleeved on the second bidirectional lead screw 51. A synchronous belt 56 is wound between the first bidirectional lead screw 41 and the second bidirectional lead screw 51.
[0053] Reference Figure 2 , Figure 3 The second bidirectional lead screw 51 has movable seats 55 fitted at both ends, and the second bidirectional lead screw 51 is threadedly engaged with the movable seats 55. A movable groove 57 is formed on the inner wall of the mounting cavity 54, and the length direction of the movable groove 57 is consistent with the length direction of the first side plate 11. The movable seats 55 slide against the inner wall of the movable groove 57. The movable seats 55 correspond one-to-one with the locking blocks 13, and the movable seats 55 are fixedly connected to the locking blocks 13.
[0054] The operator slowly moves the first panel 121 and the second panel 122 downwards, causing the first side panel 11 to insert into the mounting slot 123 and the locking block 13 to insert into the slot 124. When the locking block 13 moves downwards and contacts the insert 62, the locking block 13, through its inclined surface, causes the insert 62 to enter the slide groove 125, at which point the spring 63 is compressed. The locking block 13 continues to descend until the insert 62 is directly opposite the slot 131. Under the elastic force of the spring 63, the insert 62 enters the slot 131, thus locking the locking block 13. The fixed plate 64 and the pull rod 61 facilitate the operator's control of the position of the insert 62, thereby separating the insert 62 from the locking block 13.
[0055] The operator rotates handwheel 44, which drives worm gear 43 to rotate. The cooperation between worm gear 43 and worm wheel 42 drives the first bidirectional lead screw 41 to rotate. The rotation of the first bidirectional lead screw 41 causes adjacent abutment blocks 112 to move away from each other until the abutment blocks 112 abut against the inner wall of the limiting groove 32, thereby strengthening the stability of the first side plate 11. At the same time, the rotation of the first bidirectional lead screw 41 causes the drive pulley 52 to rotate. The rotation of the drive pulley 52 drives the synchronous belt 56 to rotate. The rotation of the synchronous belt 56 drives the driven pulley 53 to rotate. The rotation of the driven pulley 53 causes the second bidirectional lead screw 51 to rotate. The rotation of the second bidirectional lead screw 51 causes adjacent moving seats 55 to move closer to each other, thereby moving the locking block 13. The locking block 13 drives the second side plate 12 to move, thereby achieving the abutment of the rubber pad 114 against the inner wall of the mounting groove 123, thus improving the connection strength between the first side plate 11 and the second side plate 12.
[0056] Reference Figure 1 , Figure 4 The stirring rod 2 is disposed between the first panel 121 and the second panel 122. Three stirring rods 2 are provided, spaced apart along the length of the first panel 121. Each stirring rod 2 includes a fixed section 21, a rotating section 22, and a stirring section 23. The fixed section 21 passes through the first panel 121 and is fixedly connected to it. The rotating section 22 passes through the second panel 122 and is rotatably connected to it.
[0057] Reference Figure 5 Each rotating section 22 is equipped with a rotating pulley 24. Two rotating pulleys 24 are fixedly fitted on the middle rotating section 22, and a rotating pulley 24 for cooperating with the adjacent rotating pulley 24 is fixedly fitted on the rotating sections 22 on both sides. A belt 25 is wound between the cooperating rotating pulleys 24.
[0058] Reference Figure 5The stirring section 23 is hollow, and multiple stirring rings 231 are arranged on its outer circumference. The stirring rings 231 are fixedly connected to the stirring rod 2. An annular cavity 232 is formed inside the stirring ring 231, and both ends of the annular cavity 232 are connected to the inner cavity of the stirring section 23. One end of the stirring section 23 is fitted onto the fixed section 21, and the stirring section 23 is rotatably connected to the fixed section 21. The other end of the stirring section 23 is fitted onto the rotating section 22, and the stirring section 23 and the rotating section 22 are threaded together. A sealing ring 26 is fixedly connected to the end of the stirring section 23 near the fixed section 21, and the sealing ring 26 is slidably engaged with the fixed section 21.
[0059] Reference Figure 1 A rotating assembly 7 is provided on template 1. The rotating assembly 7 includes a rotating motor 71, a driving gear 72, and a driven gear 73. The rotating motor 71 is mounted on the second panel 122. The driving gear 72 is sleeved on the output shaft of the rotating motor 71. The driven gear 73 is fixedly sleeved on the rotating section 22 located on one side of the first panel 121. The driven gear 73 and the driving gear 72 mesh with each other. When the operator starts the rotating motor 71, the output shaft of the rotating motor 71 drives the driving gear 72 to rotate. The rotation of the driving gear 72 drives the driven gear 73, which in turn drives the rotating section 22 to rotate. The rotating gear on the rotating section 22, in conjunction with the belt 25, drives the entire rotating section 22 to rotate synchronously. The rotation of the rotating section 22 drives the mixing section 23 to rotate, thereby mixing the concrete at the bottom of the foundation and improving the density of the concrete.
[0060] Reference Figure 4 , Figure 5 Three circulating water pipes 8 are installed inside the stirring rods 2, each corresponding to one of the three stirring rods 2. One end of each circulating water pipe 8 is fixedly connected to the fixed section 21, and the other end extends into the stirring section 23. A water guide 81 is installed at the end of the circulating water pipe 8 away from the fixed section 21. A water supply pipe 82 is installed on the fixed section 21, and a water inlet cavity 83 is provided inside the fixed section 21 for connecting to the water supply pipe 82. A connecting hole 84 is provided on the inner wall of the water inlet cavity 83 for connecting to the stirring section 23. A connecting pipe 85 is provided at the end of the circulating water pipe 8 outside the fixed section 21. One end of the connecting pipe 85 is connected to the circulating water pipe 8, and the other end of the circulating water pipe 8 is connected to the water supply pipe 82 on the adjacent fixed section 21.
[0061] Reference Figure 4 , Figure 5 A water storage tank 9 for storing cooling water is installed on the pad 3, and a water pump 91 is installed outside the water storage tank 9. The water supply pipe 82 on the stirring rod 2 located on one side of the first panel 121 is connected to the outlet of the water pump 91, the inlet of the water pump 91 is connected to the water storage tank 9, and the connecting pipe 85 on the stirring rod 2 located on the other side of the first panel 121 is connected to the water storage tank 9.
[0062] Reference Figure 4 The first panel 121 is provided with three liquid inlet pipes 86, which correspond one-to-one with the three circulating test tubes. The liquid inlet pipes 86 are arranged vertically, and the bottom of the liquid inlet pipes 86 passes through the fixed section 21 and is connected to the circulating water pipe 8. The top of the liquid inlet pipes 86 extends out of the first panel 121, and an atomizing nozzle 87 is installed on the end of the liquid inlet pipes 86 that extends out of the first panel 121.
[0063] When the operator starts the water pump 91, the cooling water circulates between the circulating water pipe 8 and the water storage tank 9. Passing through the concrete, the cooling water removes heat from the concrete, reducing the impact of thermal expansion and contraction and thus improving the quality of the foundation. Simultaneously, when the operator needs to cure the concrete surface, they can activate the atomizing nozzle 87. Cooling water enters the atomizing nozzle 87 through the inlet pipe 86 and is then sprayed out from the nozzle to cure the concrete surface.
[0064] The implementation principle of the bridge abutment construction equipment and construction method in this application embodiment is as follows: When the operator pours concrete into the formwork 1, the operator starts the rotating motor 71. The output shaft of the rotating motor 71 rotates, driving the drive gear 72 to rotate. The rotation of the drive gear 72 drives the driven gear 73 to rotate, thereby causing the rotating section 22 to rotate. The rotating section 22 rotates synchronously through the cooperation of the rotating pulley 24 and the belt 25. The rotation of the rotating section 22 drives the mixing rod 2 to rotate. The rotation of the mixing rod 2 makes the concrete at the bottom of the abutment fully compacted, which is beneficial to improving the concrete quality.
[0065] This application also discloses a construction method for bridge pier caps. The construction method for bridge pier caps includes the following steps:
[0066] S1. Construct the cushion layer 3 on top of the pile foundation;
