Description

Technical Field

[0001] This application relates to the technical field of bridge pier retaining components, and in particular to a bridge pier retaining mechanism during construction. Background Technology

[0002] During the construction of water supply pipelines, bored piles are used to drill ground holes, and steel cages are suspended and inserted into the ground holes. When the water supply pipeline project crosses the railway, bored piles need to be installed at close range. In such cases, the bored piles and steel cages may tilt. However, since the construction points of the bored piles and steel cages are close to the bridge piers, the overturning of the bored pile machine and the collapse of the steel cages may cause damage to the high-speed railway bridge piers.

[0003] The existing announcement number CN222648569U, entitled "A Spliced ​​Bridge Pier Collision Protection Device," includes a pier body. The device further includes: a protective device installed on the outer side of the pier body; and a retaining device installed on both sides below the pier body. The protective device isolates and protects the outer wall of the pier body, while the retaining device isolates the soil near the pier body, minimizing soil erosion. The protective device includes two first protective plates, both installed on the outer wall of the pier body. This utility model relates to the field of bridge pier technology. This spliced ​​bridge pier collision protection device, through the cooperation of the pier body and the protective device, can improve the impact resistance of the pier body, minimizing damage from impacts, effectively ensuring the pier's load-bearing and support capacity, and is quick to install and convenient to construct, greatly reducing operation time.

[0004] Regarding the aforementioned technologies, the inventors discovered that the bridge pier anti-collision protection device uses multiple protective plates to form a protective enclosure around the bridge pier to protect it. However, the enclosure lacks buffer components and cannot absorb or mitigate the impact force when hit by external objects, resulting in deformation of the enclosure due to hard impact, which is not conducive to improving the service life of the bridge pier enclosure. Utility Model Content

[0005] In order to overcome the problem that existing fences lack buffer components and cannot absorb and mitigate impact forces when hit by external objects, resulting in deformation of the fences due to hard impacts, which is not conducive to improving the service life of bridge pier protection, this application provides a bridge pier protection mechanism during the construction process.

[0006] The technical solution for a bridge pier retaining structure during construction provided in this application is as follows:

[0007] A bridge pier retaining structure during construction includes a fixing component and a protective component. The fixing component includes an anchor frame, which is fixed to the ground by ground nails. Guide strips are horizontally fixed on both sides of the top surface of the anchor frame. An assembly slide frame is horizontally slidably assembled on the guide strip of the anchor frame. An assembly screw hole strip is vertically provided on the top surface of the assembly slide frame. Multiple screw holes are horizontally opened through the assembly screw hole strip in the vertical direction. A protective component is vertically provided on the assembly screw hole strip. The protective component includes an assembly frame, which is vertically slidably inserted into the assembly screw hole strip. Multiple brackets are horizontally fixed on the outer side of the assembly frame in the vertical direction. Damping rods are horizontally fixed at both ends of the anchor frame, and the other end of the damping rod is fixed to the assembly slide frame. A buffer spring is horizontally sleeved on the outside of the damping rod, and the two ends of the buffer spring are respectively fixed to the end of the anchor frame and the assembly slide frame.

[0008] By adopting the above technical solution, during water supply construction, when drilling near the bridge pier and subsequently hoisting and firing the reinforcing cage, to prevent the drill rod and reinforcing cage from tilting and falling and impacting the bridge pier, when surrounding the bridge pier at the construction point with protection, firstly, the anchor frame in the fixing component is fixed by passing ground nails through the anchor frame. Then, the assembly bolt strip is vertically fixed to the assembly slide frame. Then, the assembly frame on the protective component is vertically inserted into the assembly bolt strip. When the drill rod and reinforcing cage tilt and fall and impact the assembly frame, the assembly bolt strip causes the assembly slide frame to slide on the guide bar of the anchor frame. The assembly slide frame resists the extension of the damping rod and the deformation of the buffer spring, absorbing and offsetting the impact on the assembly frame. The damping rod recovers the damping force to offset the deformation potential energy of the buffer spring. By setting up the bridge pier protection buffer component, it is possible to prevent the enclosure from being unable to absorb and reduce the impact force when it is hit by external objects, reduce the deformation of the enclosure caused by hard impacts, and help to extend the service life of the bridge pier enclosure.

[0009] Optionally, an elastic arc sheet is horizontally fixed on the outer vertical end face of the bracket, and a soft pad is fixed on the outer wall of the elastic arc sheet.

[0010] By adopting the above technical solution, in order to ensure the deformation resistance of the support against external impact, the elastic arc plate and soft pad installed on the support cause the elastic arc plate to deform when an external object is impacted, thus ensuring the deformation resistance of the support against impact.

[0011] Optionally, the outer side of the assembly frame has a horizontally penetrating screw hole along the vertical direction, and the assembly frame and the assembly screw hole strip are fixedly assembled by the threaded screws passing through the screw holes.

[0012] By adopting the above technical solution, the assembly frame and the assembly screw hole strip are fixedly assembled by the threaded screws passing through the screw holes, which facilitates the later locking of the assembly frame onto the assembly screw hole strip.

[0013] Optionally, the bottom end of the assembly screw hole strip is horizontally fixed with an assembly screw hole block, and the assembly screw hole block is slidably inserted into the assembly slide frame.

[0014] By adopting the above technical solution, the assembly screw hole block at the bottom of the assembly screw hole strip is inserted into the assembly slide frame to limit and support the installation of the assembly screw hole strip on the assembly slide frame.

[0015] Optionally, the assembly slide frame has vertically opened screw holes, and a locking screw is threaded through the assembly screw hole block and the locking screw is threaded into the screw hole of the assembly slide frame.

[0016] By adopting the above technical solution, when the limit support is installed on the assembly slide frame, the locking screw is manually rotated and threaded into the screw hole of the assembly slide frame, thus completing the installation of the assembly screw strip on the assembly slide frame.

[0017] Optionally, a slide bar is horizontally fixed on one end face of the anchoring frame, and a slider is horizontally slidably assembled on the slide bar. A screw groove is vertically opened on the top surface of the slider, and a connecting stud is threaded in the screw groove of the slider.

[0018] By adopting the above technical solution, a slide bar is fixed on one end face of the anchoring frame, a slider is horizontally slidably assembled on the slide bar, and a connecting stud is threaded in the screw groove on the slider, which facilitates the later locking and connection into a whole by the connecting stud.

[0019] Optionally, a perforated plate is horizontally fixed on the other end face of the anchoring frame, and the perforated plate is rotatably connected to the slider via a connecting stud.

[0020] By adopting the above technical solution, when multiple anchor frames form a retaining wall around the pier, the perforated plates at the adjacent ends of the multiple anchor frames are inserted into the slider, and then connected into a whole by connecting studs, thereby forming a whole retaining wall around the pier.

[0021] Optionally, the assembly frame has a fixed box inside, and the box is filled with cushioning filler.

[0022] By adopting the above technical solution, the assembly frame is fixed with a box filled with buffer filler. The buffer filler is a non-Newtonian fluid. The non-Newtonian fluid is a viscoelastic fluid with restoring force, which facilitates the absorption and offset of impact force in the later stage, reducing the impact force on the fence.

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

[0024] During water supply construction, when drilling near bridge piers and subsequently hoisting and firing reinforcing cages, to prevent the drill rods and reinforcing cages from tilting and falling onto the bridge piers, protective measures are implemented at the pier locations. First, the anchoring frame in the fixing components is secured by ground nails. Then, the assembly bolt strip is vertically fixed to the assembly sliding frame. Next, the assembly frame on the protective component is vertically inserted into the assembly bolt strip. When the drill rods and reinforcing cages tilt and fall onto the assembly frame, the assembly bolt strip causes the assembly sliding frame to slide on the guide bar of the anchoring frame. The assembly sliding frame resists the extension of the damping rod and the deformation of the buffer spring, absorbing and offsetting the impact on the assembly frame. The damping rod recovers its damping force to offset the deformation potential energy of the buffer spring. This pier protection buffer component prevents the enclosure from being unable to absorb and mitigate impact forces when hit by external objects, reducing deformation caused by hard impacts and extending the service life of the bridge pier enclosure.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a bridge pier retaining structure during construction. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A bridge pier retaining structure during construction includes a fixing component 1 and a protective component 2. The fixing component 1 includes an anchor frame 11, which is fixed to the ground by ground nails 12. Guide strips 13 are horizontally fixed on both sides of the top surface of the anchor frame 11. An assembly slide frame 14 is horizontally slidably assembled on the guide strips 13 of the anchor frame 11. An assembly screw hole strip 15 is vertically arranged on the top surface of the assembly slide frame 14. Multiple screw holes are horizontally penetrated along the vertical direction on the assembly screw hole strip 15. A protective component 2 is provided, which includes an assembly frame 21. The assembly frame 21 is vertically slidably inserted into the assembly screw hole strip 15. Multiple brackets 23 are horizontally fixed on the outer side of the assembly frame 21 along the vertical direction. Both ends of the anchor frame 11 are horizontally fixed with damping rods 111, and the other end of the damping rods 111 is fixed on the assembly slide frame 14. A buffer spring 112 is horizontally sleeved on the outside of the damping rods 111, and both ends of the buffer spring 112 are fixed on the end of the anchor frame 11 and the assembly slide frame 14, respectively.

[0033] By adopting the above technical solution, during water supply construction, when drilling near the bridge pier and subsequently hoisting the reinforcing cage, to prevent the drill rod and reinforcing cage from tilting and falling and impacting the bridge pier, when surrounding the bridge pier at the construction site with protection, firstly, the anchor frame 11 in the fixing component 1 is fixed by passing the anchor frame 11 through the ground nail 12. Then, the assembly screw hole strip 15 is vertically fixed to the assembly sliding frame 14. Then, the assembly frame 21 on the protective component 2 is vertically inserted into the assembly screw hole strip 15. Later, the drill rod and reinforcing cage tilting and falling will impact the bridge pier. When the tilting impacts the assembly frame 21, the assembly bolt strip 15 causes the assembly slide frame 14 to slide on the guide strip 13 of the anchor frame 11. The assembly slide frame 14 presses against the extension of the damping rod 111 and the deformation of the buffer spring 112, absorbing and offsetting the impact on the assembly frame 21. The damping rod 111 recovers its damping force to offset the deformation potential energy of the buffer spring 112. The pier protection buffer component is set to prevent the fence from being unable to absorb and reduce the impact force when it is hit by external objects, reduce the deformation of the fence caused by hard impacts, and help to improve the service life of the pier enclosure.

[0034] Reference Figure 5 An elastic arc plate 24 is horizontally fixed on the outer vertical end face of the bracket 23, and a soft pad 25 is fixed on the outer wall of the elastic arc plate 24. In order to ensure the deformation resistance of the bracket 23 against external impact, the elastic arc plate 24 and the soft pad 25 provided on the bracket 23 cause the elastic arc plate 24 to deform when an external object is impacted, thus ensuring the deformation resistance of the bracket 23 against impact.

[0035] Reference Figure 3 and Figure 5The assembly frame 21 has horizontally protruding screw holes along its outer side in the vertical direction. The assembly frame 21 and the assembly screw hole strip 15 are fixedly assembled by assembly screws 22 threaded through the screw holes. This assembly of the assembly frame 21 and the assembly screw hole strip 15 facilitates later locking of the assembly frame 21 onto the assembly screw hole strip 15. An assembly screw hole block 16 is horizontally fixed to the bottom end of the assembly screw hole strip 15, and the assembly screw hole block 16 is slidably inserted into the assembly slide frame 14. The assembly screw hole block 16 at the bottom of the assembly screw hole strip 15 is inserted into the assembly slide frame 14, limiting and supporting the installation of the assembly screw hole strip 15 on the assembly slide frame 14.

[0036] Reference Figure 3 and Figure 5 The assembly slide frame 14 has vertically protruding screw holes, and a locking screw 17 is threaded through the assembly screw hole block 16, with the locking screw 17 threaded into the screw hole of the assembly slide frame 14. When the limit support is installed on the assembly screw hole strip 15 on the assembly slide frame 14, the locking screw 17 is manually rotated to thread into the screw hole of the assembly slide frame 14, thus completing the installation of the assembly screw hole strip 15 on the assembly slide frame 14.

[0037] Reference Figure 3 and Figure 4 A sliding strip 18 is horizontally fixed to one end face of the anchoring frame 11, and a slider 181 is horizontally slidably assembled on the sliding strip 18. A threaded groove 182 is vertically opened on the top surface of the slider 181, and a connecting stud 183 is threaded into the threaded groove 182 of the slider 181. The sliding strip 18 is fixed to one end face of the anchoring frame 11, and the slider 181 is horizontally slidably assembled on the sliding strip 18. The connecting stud 183 is threaded into the threaded groove 182 of the slider 181, facilitating later locking and connection into a single unit via the connecting stud 183. A perforated plate 19 is horizontally fixed to the other end face of the anchoring frame 11, and the perforated plate 19 is rotatably connected to the slider 181 via the connecting stud 183. When multiple anchoring frames 11 form a retaining wall around the pier, the perforated plates 19 at adjacent ends of the multiple anchoring frames 11 are inserted into the slider 181, and then locked and connected into a single unit via the connecting stud 183, thus forming a single retaining wall around the pier.

[0038] Reference Figure 5 The assembly frame 21 has a box 26 fixed inside, and the box 26 is filled with buffer filler 261. The assembly frame 21 is fixed with a box 26 filled with buffer filler 261. The buffer filler 261 is a non-Newtonian fluid. The non-Newtonian fluid is a viscoelastic fluid with restoring force, which is convenient for offsetting and absorbing impact force in the later stage, reducing the impact force on the fence.

[0039] The implementation principle of a bridge pier retaining structure in the construction process according to an embodiment of this application is as follows: During water supply construction, when drilling near the bridge pier and later hoisting the steel cage, in order to prevent the drill rod and steel cage from tilting and falling and hitting the bridge pier, multiple anchor frames 11 are used to form a retaining structure around the bridge pier at the construction point. The perforated plates 19 at the adjacent ends of the multiple anchor frames 11 are inserted into the slider 181, and then locked and connected into a whole by connecting studs 183, thereby forming a whole retaining structure for the bridge pier. First, the anchor frames 11 in the fixing component 1 are fixed by the ground nails 12 penetrating through the anchor frames 11. Then, when the limiting support is installed and the assembly screw hole strip 15 is installed on the assembly slide frame 14, the locking screw 17 is manually rotated. Assembled in the screw holes of the assembly slide frame 14, the assembly screw strip 15 is completed on the assembly slide frame 14. Then, the assembly frame 21 on the protective component 2 is vertically inserted into the assembly screw strip 15. Later, when the drill rod and the steel cage tilt and fall and hit the assembly frame 21, the assembly screw strip 15 causes the assembly slide frame 14 to slide on the guide strip 13 of the anchor frame 11. The assembly slide frame 14 presses against the extension of the damping rod 111 and the deformation of the buffer spring 112, absorbing and offsetting the impact on the assembly frame 21. The damping rod 111 recovers the damping force to offset the deformation potential energy of the buffer spring 112. The pier protection buffer component is set to prevent the fence from being unable to absorb and reduce the impact force when it is hit by external objects, reduce the deformation of the fence caused by hard impact, and help to improve the service life of the pier enclosure.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
