Description

Technical Field

[0001] This utility model relates to the field of bridge abutment structure technology, and in particular to a bridge abutment structure with a large-volume concrete mix ratio. Background Technology

[0002] In the field of bridge engineering, bridge abutments are key components connecting the superstructure and substructure of a bridge. Their stability and durability play a vital role in the safety of the entire bridge. With the rapid development of transportation, the scale of bridges is constantly expanding. During bridge construction, it is necessary to pour large volumes of concrete inside the bridge abutments to improve the stability of the bridge abutment structure.

[0003] During the concrete pouring process, the concrete impacts the internal supporting steel frame of the bridge abutment, causing deformation of the supporting steel frame and thus affecting the stability of the bridge abutment structure.

[0004] To address this issue, this utility model proposes a bridge abutment structure with a large-volume concrete mix ratio. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to propose a bridge pier structure with a large-volume concrete mix ratio, including a pier body, four foundation piles fixedly connected to one side of the pier body, a buffer mechanism provided inside the pier body, a pier column fixedly connected inside the pier body, and a connecting ring fixedly connected to the outside of the pier column.

[0007] The buffer mechanism includes two connecting arc plates, two first buffer plates, and two second buffer plates. The inner walls of the two connecting arc plates are fitted to the outer walls of the pier. One side of the two connecting arc plates is connected and fixed to one side of the connecting ring by several first bolts. Several buffer through holes are opened inside the two first buffer plates and the two second buffer plates.

[0008] Preferably, one side of each of the two first buffer plates is fixedly connected to a first inclined plate, and one side of each of the two first inclined plates is fixedly connected to one side of the main body of the support platform by a number of second bolts.

[0009] The technical effect achieved by adopting the above scheme is that the impact force during concrete pouring can be reduced by the first inclined plate in conjunction with the inclined surface of the main body of the foundation.

[0010] Preferably, in any of the above schemes, a first connecting plate is fixedly connected to one side of each of the two first buffer plates, and one side of each of the two first connecting plates is fixedly connected to the outer wall of the connecting arc plate by a third bolt.

[0011] Preferably, in any of the above schemes, the interior of the two first buffer plates is sleeved with the exterior of the two connecting arc plates, and one side of the two first buffer plates is in contact with each other.

[0012] Preferably, in any of the above schemes, a second inclined plate is fixedly connected to one side of each of the two second buffer plates, and one side of each of the two second inclined plates is fixedly connected to one side of the main body of the support platform by a number of fourth bolts.

[0013] Preferably, in any of the above schemes, a second connecting plate is fixedly connected to one side of each of the two second buffer plates, and the inner walls of the two second connecting plates are fixedly connected to the outer wall of the connecting arc plate by a fifth bolt.

[0014] The technical effect achieved by adopting the above solution is that the second connecting plate is connected and fixed to the connecting arc plate by the fifth bolt, thereby further connecting and fixing the second buffer plate.

[0015] Preferably, in any of the above schemes, the inner walls of the two second buffer plates are sleeved with the outer sides of the two connecting arc plates, and one side of the two second buffer plates is in contact with each other.

[0016] Preferably, in any of the above schemes, a supporting steel frame is fixedly connected inside the main body of the pier, and the outside of the pier column is located inside the supporting steel frame.

[0017] The technical effect achieved by adopting the above scheme is that by setting a supporting steel frame inside the main body of the foundation, the stability of the main body of the foundation after concrete pouring can be improved.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0019] By incorporating a buffer mechanism to cushion the concrete pouring process, the direct impact of concrete on the supporting steel reinforcement frame is prevented. The first buffer plate initially buffers the impact force of the poured concrete. Subsequently, the concrete is diverted through the buffer holes on the first buffer plate, dispersing the overall impact force into multiple smaller impact forces. The concrete, after being buffered by the first buffer plate, then passes through the second buffer plate for further buffering. Finally, the concrete, buffered by both the first and second buffer plates, enters the interior of the pier structure for pouring. The first and second buffer plates, together with the buffer holes, progressively buffer the impact force during concrete pouring, allowing the concrete to flow evenly and dispersedly during pouring. This prevents the concentrated falling of concrete from generating a large impact force, thus solving the problem that the concrete pouring process might impact the supporting steel reinforcement frame inside the bridge pier, causing deformation of the steel reinforcement frame. This contributes to improving the stability of the bridge pier structure.

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0028] Example 1: As Figures 1 to 5 As shown, a bridge abutment structure with a large-volume concrete mix design includes a main abutment 1. The main purpose of the large-volume concrete mix design is to reduce concrete cracking due to temperature changes while meeting the basic performance requirements of concrete strength, durability, and workability, thereby affecting the stability of the bridge abutment structure. Through reasonable mix design, selection of appropriate cement types and dosages, and the addition of admixtures and additives, the temperature changes of concrete can be effectively controlled, thereby improving the stability of the bridge abutment structure. The large-volume concrete mix design is a known technology, and those skilled in the art can and should understand its specific functions and structure. Therefore, this application mainly describes the bridge abutment structure. The inner perimeter of the main abutment 1 is inclined, allowing the main abutment 1 to cooperate with the first inclined plate 304 and the second inclined plate 306, so that the inclined surface can initially buffer the impact force during concrete pouring. Four foundation piles 2 are fixedly connected to one side of the main abutment 1. The number of foundation piles 2 can be adjusted according to work requirements. A buffer mechanism 3 is provided inside the main abutment 1. A pier 4 is fixedly connected inside the main body 1 of the bridge abutment. A connecting ring 401 is fixedly connected to the outside of the pier 4. The connecting ring 401 provides a position for the connection and fixing of the connecting arc plate 301, which facilitates the connection and fixing of the buffer mechanism 3. It should be noted that when using the bridge abutment structure, the relevant structures need to be installed first. The supporting steel frame 5 should be installed inside the main body 1 of the bridge abutment first, and then the pier 4 should be installed inside the supporting steel frame 5 inside the main body 1 of the bridge abutment. Then the buffer mechanism 3 is installed and fixed. Finally, the concrete is poured to connect the pier 4 and the main body 1 of the bridge abutment. Of course, the concrete needs to be poured in layers to avoid segregation. A vibrator is also needed to compact the concrete to make it dense. When vibrating, attention should be paid to the insertion depth of the vibrator and the vibration time to avoid over-vibration or under-vibration. After the concrete of the bridge abutment structure is poured, it should also be cured in time by covering it with plastic film to keep the surface of the concrete moist to ensure the normal development of the concrete strength and durability.

[0029] The buffer mechanism 3 includes two connecting arc plates 301, two first buffer plates 302, and two second buffer plates 303. The inner walls of the two connecting arc plates 301 are fitted to the outer walls of the pier 4. One side of the two connecting arc plates 301 is connected and fixed to one side of the connecting ring 401 by several first bolts. The connecting arc plates 301 are connected and fixed to the connecting ring 401 by several first bolts, so that the buffer mechanism 3 can be connected and fixed to the pier 4. This eliminates the need to drill holes in the pier 4 to connect and fix the buffer mechanism 3 to the pier 4, avoiding the impact of drilling holes on the pier 4 on the support stability of the pier 4. Several buffer through holes are opened inside the two first buffer plates 302 and the two second buffer plates 303. The first buffer plates 302 and the second buffer plates 303 work together with the buffer through holes to buffer the impact force during concrete pouring in stages, so that the concrete can flow evenly and dispersedly during pouring, avoiding the large impact force generated by the concentrated falling of concrete.

[0030] Each of the two first buffer plates 302 has a first inclined plate 304 fixedly connected to one side. Each of the two first inclined plates 304 is fixed to one side of the pier body 1 by several second bolts. The first inclined plates 304, in conjunction with the inclined surface of the pier body 1, can reduce the impact force during concrete pouring. When concrete is poured inside the bridge pier, the concrete will fall first onto the inclined surface of the pier body 1, the first inclined plate 304, and the first buffer plate 302. At this time, the first buffer plate 302 will initially buffer the impact force of the concrete pouring. Then the concrete will be diverted through the buffer through holes on the first buffer plate 302, thus dispersing the overall impact force into multiple smaller impact forces, thereby reducing the impact force during concrete pouring. At this time, the concrete will reach the second buffer plate 303 and the second inclined plate 306.

[0031] Each of the two first buffer plates 302 has a first connecting plate 305 fixedly connected to one side. Each of the two first connecting plates 305 is connected and fixed to the outer wall of the connecting arc plate 301 by a third bolt. When installing the first buffer plates 302, the second buffer plates 303 are installed first. The workers splice the two first buffer plates 302 on the outside of the connecting arc plate 301, and then connect and fix the first connecting plate 305 to the connecting arc plate 301 by the third bolt. This connects and fixes one side of the first buffer plate 302 to the connecting arc plate 301 and the pier 4. Then, the first inclined plate 304 is connected and fixed to the inclined surface of the foundation body 1 by the second bolt, so that one end of the first buffer plate 302 is connected and fixed to the foundation body 1. This installs and fixes the two first buffer plates 302 inside the foundation body 1 and outside the pier 4.

[0032] The interior of the two first buffer plates 302 is sleeved with the exterior of the two connecting arc plates 301, and one side of the two first buffer plates 302 is in contact with each other.

[0033] Each of the two second buffer plates 303 has a second inclined plate 306 fixedly connected to one side. Each of the two second inclined plates 306 is fixed to one side of the pier body 1 by several fourth bolts. After the concrete is buffered by the first buffer plate 302, it will reach one side of the second buffer plate 303 and the second inclined plate 306. At this time, the concrete buffered by the first buffer plate 302 will be further buffered by the second buffer plate 303. Then, the concrete buffered by the first buffer plate 302 and the second buffer plate 303 will enter the interior of the pier body 1 for pouring. This avoids the supporting steel frame 5 inside the pier body 1 being directly impacted by the concrete pouring, which would cause the steel to deform and affect the stability of the bridge pier structure.

[0034] A second connecting plate 307 is fixedly connected to one side of each of the two second buffer plates 303. The inner walls of the two second connecting plates 307 are connected and fixed to the outer wall of the connecting arc plate 301 by a fifth bolt. When installing the buffer mechanism 3, the operator first splices the two second buffer plates 303 on the outside of the two connecting arc plates 301, and then connects and fixes the second connecting plate 307 to the connecting arc plate 301 by the fifth bolt, so that one end of the second buffer plate 303 is connected and fixed to the outside of the connecting arc plate 301 and the pier 4. Then, the second inclined plate 306 is connected and fixed to the inclined surface on one side of the pier body 1 by the fourth bolt, so that one end of the second buffer plate 303 is connected and fixed to one side of the pier body 1. In this way, the second buffer plate 303 is installed and fixed inside the pier body 1. Then the first buffer plate 302 is installed and fixed.

[0035] The inner walls of the two second buffer plates 303 are sleeved with the outer walls of the two connecting arc plates 301, and one side of the two second buffer plates 303 is in contact with each other.

[0036] A supporting steel frame 5 is fixedly connected inside the main body of the pier 1. The outside of the pier column 4 is set inside the supporting steel frame 5. By setting the supporting steel frame 5 inside the main body of the pier 1, the stability of the main body of the pier 1 after concrete pouring can be improved.

[0037] A bridge pier structure with a large-volume concrete mix design operates on the following principle:

[0038] When using the bridge abutment structure, workers connect and fix the connecting arc plate 301 to the connecting ring 401 outside the pier 4 using the first bolt. Then, two second buffer plates 303 are assembled onto the outside of the two connecting arc plates 301. Next, the second connecting plate 307 is connected and fixed to the connecting arc plate 301 using the fifth bolt, so that one end of the second buffer plate 303 is connected and fixed to the outside of the connecting arc plate 301 and the pier 4. Then, the second inclined plate 306 is connected and fixed to the inclined surface on one side of the abutment body 1 using the fourth bolt, so that one end of the second buffer plate 303 is connected and fixed to one side of the abutment body 1. This completes the installation and fixation of the second buffer plate 303. Inside the main body 1 of the pier, the first buffer plate 302 is then installed and fixed. The workers splice the two first buffer plates 302 to the outside of the connecting arc plate 301, and then connect and fix the first connecting plate 305 to the connecting arc plate 301 with the third bolt. This connects and fixes one side of the first buffer plate 302 to the connecting arc plate 301 and the pier 4. Then, the first inclined plate 304 is connected and fixed to the inclined surface of the main body 1 of the pier with the second bolt, so that one end of the first buffer plate 302 is connected and fixed to the main body 1 of the pier. This installs and fixes the two first buffer plates 302 inside the main body 1 and outside the pier 4.

[0039] Then, during the concrete pouring process inside the bridge abutment, the concrete falls first onto the inclined surfaces of the abutment body 1, the first inclined plate 304, and the first buffer plate 302. At this point, the first buffer plate 302 initially buffers the impact of the concrete pouring. Subsequently, the concrete is diverted through the buffer holes on the first buffer plate 302, thus dispersing the overall impact into multiple smaller impacts, thereby reducing the impact force during concrete pouring. The concrete then reaches the second buffer plate 303 and the second inclined plate 306, and after being buffered by the first buffer plate 302, it further... The impact force is buffered by the second buffer plate 303, and then the concrete buffered by the first buffer plate 302 and the second buffer plate 303 enters the interior of the pier body 1 for pouring. The first buffer plate 302 and the second buffer plate 303 work together with the buffer through holes to buffer the impact force of the concrete pouring step by step, so that the concrete can flow evenly and dispersedly for pouring, avoiding the large impact force generated by the concentrated falling of concrete, and preventing the supporting steel frame 5 inside the pier body 1 from being directly impacted by the concrete pouring, which would cause the steel to deform and affect the stability of the bridge pier structure.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
