Description

Technical Field

[0001] This invention relates to the field of roadbed construction technology, and more specifically, to a box abutment transition structure and its construction method. Background Technology

[0002] Due to factors such as topography, existing roads, and alignment, the connection between bridges and roadbeds is often formed by backfilling the abutments. However, in cases of high embankments and intersections, traditional design and construction methods cannot meet the actual needs of the site, and the structural stress and deformation are difficult to meet the relevant specifications and standards. As a result, traditional roadbed transition methods cannot be seamlessly connected to the bridge structure.

[0003] Among the existing published documents, Chinese Patent Publication No. CN111535077A discloses a transition structure between a box-type roadbed and a bridge and its corresponding construction method. This patent achieves a consistent horizontal height between the top slab, the beam, and the top surface of the box-type roadbed section. The proposed transition structure between the box-type roadbed and the bridge and its corresponding construction method can effectively solve the transition connection problem between the box-type roadbed and the bridge structure. However, this transition structure has the following defects. When the aforementioned transition structure is being formed, each point is reinforced by two support points. This makes it difficult to accurately construct and pour concrete according to the specified data during the construction process and the subsequent concrete pouring, thus reducing the construction quality of the box abutment transition structure. Therefore, a box abutment transition structure and its construction method are provided. Summary of the Invention

[0004] To overcome the above-mentioned defects of the prior art, the present invention provides a box-type bridge abutment transition structure and its construction method.

Multiple transverse reinforcement columns are cast and fixedly connected between the concrete spacer columns and the concrete pillars from bottom to top. An edge support column is cast and fixed at one end of the concrete base frame. A concrete side support column is cast and fixed at the top of the edge support column. Multiple connecting columns are installed between the concrete side support column and the concrete pillar. A concrete layer is cast and laid at the top of the concrete side support column. Multiple concrete pillars are arranged equidistantly from front to back. The tops of both the concrete pillars and the concrete spacer columns are cast and fixed between the concrete layer. Multiple connecting columns are arranged equidistantly from bottom to top. The connecting columns are cast and fixed between the concrete side support column and the concrete pillar respectively.

[0006] Preferably, a support strip is cast and fixedly connected to one side of the concrete pouring layer, an asphalt layer is laid on the upper surface of the concrete pouring layer, a parapet wall is cast and fixed at the top of the asphalt layer, a reinforcing column is cast behind the concrete pouring layer, and a V-shaped reinforcing column is provided on one side of the reinforcing column and cast and fixed to the concrete pouring layer.

[0007] According to the above technical solution, a bottom support frame is formed by the edge support columns of the concrete bottom frame, and multiple connecting columns are supported by the concrete side columns. The concrete columns form a horizontal support through the horizontal reinforcement columns, which in turn provide horizontal support to the concrete spacer columns. The concrete spacer columns are connected and reinforced by the horizontal columns. The concrete side columns, concrete columns, and concrete spacer columns form a vertical support concrete pouring layer. The right side of the concrete pouring layer is erected on the bridge abutment, and a pouring support is formed through the connection. After pouring, an asphalt layer is laid and parapet walls are built on both sides on top of the asphalt layer.

[0008] Preferably, a casting recess is provided on one side of the outer wall of the concrete base frame, and a protective component is installed in front of the casting recess; The protective assembly includes a docking casting frame positioned in front of the casting recess. An insertion support block, which slidably engages with the casting recess, is installed on the inner wall of the docking casting frame. The insertion support block is fixedly connected to the docking casting frame. A first threaded sleeve support block is fixedly connected to one side of the casting recess. A second threaded sleeve support block is fixedly connected to the front of the docking casting frame. A transmission screw is installed on the inner wall of the first threaded sleeve support block. One end of the transmission screw is coaxially connected to a reduction drive motor. A sleeve frame plate is rotatably connected to the outer wall of the transmission screw near the reduction drive motor. A support frame is installed on one side of the reduction drive motor. A threaded sleeve vertical block is fixedly connected to the inner wall of the sleeve frame plate, located near the second threaded sleeve support block. A vertical thread is threaded into the inner part of the threaded sleeve vertical block. A vertical guide frame plate is vertically slidably connected to the outer wall of the threaded sleeve vertical block of the transmission screw. A controller is fixedly installed on one side of the outer wall of the vertical guide frame plate. The top of the vertical transmission screw extends to the top of the vertical guide frame plate and is coaxially driven to a vertical drive motor. The vertical drive motor is fixedly connected to the vertical guide frame plate. A distance sensor is fixedly connected to the vertical guide frame plate below the sleeve frame plate. The second threaded sleeve support block and the first threaded sleeve support block are both threadedly connected to the transmission screw. The two threads on the outer wall of the transmission screw are opposite and symmetrically arranged. The second threaded sleeve support block and the first threaded sleeve support block are slidably connected to the threaded sleeve vertical block. The support frame is fixedly connected to the reduction drive motor and the sleeve frame plate respectively. The support frame and the sleeve frame plate are both made of stainless steel.

[0009] According to the above technical solution, the starting reduction drive motor drives the transmission screw to rotate steadily inside the sleeve frame plate. The transmission screw drives the first threaded sleeve support block to move to the left along the inside of the sleeve frame plate under the action of the thread. At the same time, the second threaded sleeve support block moves to the right along the inside of the sleeve frame plate under the action of the thread. The casting frame and the casting recess form an outer closed state. The concrete is poured to the edge of the space enclosed by the inner wall of the casting recess and the casting frame and solidifies. When the hardness test is qualified, the controller starts the vertical drive motor to drive the vertical transmission screw to rotate inside the vertical guide frame plate. The vertical transmission screw drives the threaded sleeve vertical block to move the sleeve frame plate upward under the action of the thread. The first threaded sleeve support block and the second threaded sleeve support block respectively move the casting recess and the casting frame upward. The upward movement of the sleeve frame plate is sensed by the distance sensor.

[0010] Preferably, a sleeve frame is fixedly connected to one side of the outer wall of the casting frame, and a switching detection component is installed inside the sleeve frame; The switching detection component includes a linkage screw installed inside the sleeve frame, and a threaded linkage sleeve block is threadedly connected to the outer wall of the linkage screw. One end of the linkage screw extends to the outside of the sleeve frame and is coaxially connected to a servo reduction motor. A reduction transmission motor is fixedly installed on one side of the threaded linkage sleeve block. The reduction transmission motor is fixedly connected to the sleeve frame, and a sleeve ring block is welded to the output end of the reduction transmission motor. A sealing insertion post is fixedly connected to the inner wall of the sleeve ring block, and a hardness sensor is fixedly connected to the sleeve ring block at one end. The sealing insertion post is slidably inserted into the butt casting frame.

[0011] According to the above technical solution, the servo geared motor is started to drive the linkage screw to rotate forward inside the sleeve frame. At the same time, the linkage screw drives the threaded linkage block to move to the left along the inside of the sleeve frame under the action of the thread. The sleeve ring block drives the sealing plug to move and separate from the inside of the docking casting frame. The geared transmission motor is started to drive the sleeve ring block to rotate 180 degrees. The servo geared motor is started to drive the linkage screw to reverse, so that the threaded linkage block drives the geared transmission motor to move to the right. The geared transmission motor drives the sleeve ring block to move the sealing plug and the hardness sensor to the right. The hardness sensor can be inserted into the inside of the docking casting frame to detect the hardness of the poured concrete.

[0012] A construction method for a box girder bridge abutment transition structure, comprising the following steps: Step 1: First, drill bored piles. Based on the stress calculation and analysis of the box structure, drill bored piles are mainly installed on the outer wall and inner partition wall of the box to enhance the overall stress performance and resist load stress and strain. Step 2: Next, reinforce the pouring. Connect the reinforced pouring mechanism to the bridge abutment transition structure formed by the box-type bridge abutment and pour concrete into the joint to solidify and form the shape. Step 3: Then, pour concrete for the outer protection. After the protective components are formed to enclose the outer perimeter, pour the concrete and wait for it to solidify. Step 4: Finally, switch the detection. By switching the detection component, connect the hardness sensor to the already formed concrete to detect it. After the qualified standard is met, lift the protective component to continue to stack and form the concrete. After the transition box is completed, pour the cast-in-place reinforced concrete slab on the roadbed side. After the bridge deck leveling layer is completed, pave the bridge deck and road surface with 100mm asphalt concrete. Finally, install the expansion joint on the abutment side.

[0013] The technical effects and advantages of this invention are as follows: 1. This invention employs a reinforced casting mechanism to form a bottom support frame by supporting columns at the edge of the concrete base frame. Multiple connecting columns are supported by concrete side columns, and transverse reinforcement columns provide transverse support. These transverse reinforcement columns provide transverse support to the concrete spacer columns. The concrete side columns, concrete columns, and concrete spacer columns form a vertical support concrete casting layer. During construction and subsequent concrete casting, precise casting can be achieved at the distribution points according to specified data, improving casting stability and reducing the construction quality of the box girder abutment transition structure. Moreover, after forming a sealed box chamber inside the entire box, backfilling can be carried out manually and mechanically without the need for inspection doors or dedicated personnel. Waterproofing measures are taken for the top, bottom, and outer walls of the box, eliminating the need to consider drainage issues inside the box after completion. 2. This invention uses a protective component to activate a reduction drive motor, which drives a transmission screw to rotate stably inside the sleeve frame plate. The first threaded sleeve support block moves to the left along the inside of the sleeve frame plate under the action of the thread, while the second threaded sleeve support block moves to the right along the inside of the sleeve frame plate under the action of the thread. After the hardness reaches the standard, the controller activates a vertical drive motor to drive a vertical transmission screw to rotate inside the vertical guide frame plate. When the height sensed is the height value set by the controller, the vertical drive motor stops. This allows the casting concave frame and the butt casting frame to be precisely lifted at a specified angle after the concrete hardness is qualified, ensuring that the internal filling and casting firmness is effectively improved and the construction quality is enhanced. 3. This invention employs a switching detection component to activate a servo-reduced motor that drives a linkage screw to rotate forward inside the sleeve frame. The sleeve ring block drives the sealing plug to move and separate from the inside of the docking casting frame. The activation of the reduction transmission motor drives the sleeve ring block to rotate 180 degrees, and the activation of the servo-reduced motor drives the linkage screw to rotate in reverse. The hardness sensor can be inserted into the docking casting frame to detect the hardness of the poured concrete. It can accurately detect the hardness of the filled concrete formed inside the casting concave frame and the docking casting frame. Only after the hardness meets the standard will the upward pouring continue, ensuring that the quality of each layer of pouring can be accurately controlled, which can effectively improve the construction quality of the box abutment transition structure. Through the interaction of the above-mentioned multiple functions, firstly, precise construction and pouring are achieved at the distribution points according to the specified data. Secondly, after the concrete hardness of the pouring concave frame and the docking pouring frame is accurately determined to be qualified, it is precisely lifted at the specified angle and height. Finally, it is ensured that the hardness of each layer of pouring can be accurately switched and tested. In summary, during the construction of the box abutment transition structure, distributed and precise construction according to the specified data can be achieved. In this way, the quality of the box abutment transition structure is precisely controlled during the construction process, thereby improving the construction quality of the box abutment transition structure.

[0029] The working principle of the box-type bridge abutment transition structure of this invention is as follows: Firstly, during the pouring and support process of this invention, a bottom support frame is formed by a concrete bottom frame 1 and edge support columns 7. Concrete side pillars 8 support multiple connecting columns 6, which in turn support concrete pillars 2. Concrete pillars 2 are supported laterally by transverse reinforcement columns 5, which connect to concrete spacer pillars 3 laterally. Concrete spacer pillars 3 are reinforced laterally by transverse columns 4. Concrete side pillars 8, concrete pillars 2, and concrete spacer pillars 3 form a vertical support for the poured concrete layer 9. The right side of the poured concrete layer 9 is erected on the bridge abutment, and the pouring support is formed through the connection. After pouring, an asphalt layer 11 is laid, and parapet walls 12 are built on both sides on top of the asphalt layer 11. Reinforcement columns 13 and V-shaped reinforcement columns 14 reinforce the sides of the poured concrete layer 9. The box abutment transition structure can achieve firm support in the early stage, making it less prone to shaking and ensuring construction stability. Secondly, when the present invention performs peripheral protection, the deceleration drive motor 21 is started to drive the transmission screw 20 to rotate stably inside the sleeve frame plate 23. The transmission screw 20 drives the first threaded sleeve support block 18 to move to the left along the inside of the sleeve frame plate 23 under the action of the thread. At the same time, the second threaded sleeve support block 19 moves to the right along the inside of the sleeve frame plate 23 under the action of the thread. The docking casting frame 16 drives the insertion support block 17 to be inserted into the casting concave frame 15. The insertion support block 17 can play an embedding and insertion role on the inner wall of the casting concave frame 15. The docking casting frame 16 and the casting concave frame 15 form a closed peripheral state. The concrete is poured to the edge of the space enclosed by the inner wall of the casting concave frame 15 and the docking casting frame 16 to form and solidify. Finally, during the switching detection of this invention, the servo reduction motor 36 is started, driving the linkage screw 30 to rotate clockwise inside the sleeve frame 29. Simultaneously, the linkage screw 30 drives the threaded linkage block 31 to move leftward along the inside of the sleeve frame 29 under the action of the thread. The threaded linkage block 31 drives the reduction transmission motor 32 to move the sleeve ring block 33 to the left. The sleeve ring block 33 drives the sealing insertion post 34 to move and separate from the inside of the casting frame 16. The reduction transmission motor 32 is started, driving the sleeve ring block 33 to rotate 180 degrees. After the sleeve ring block 33 drives the sealing insertion post 34 and the hardness sensor 35 to rotate 180 degrees, the servo reduction motor 36 is started, driving the linkage screw 30 to reverse direction. This causes the threaded linkage block 31 to drive the reduction transmission motor 32 to move rightward. The reduction transmission motor 32 drives the sleeve ring block 33 to move the sealing insertion post 34 and the hardness sensor 35 to the right. Sensor 35 can be inserted into the casting frame 16 to detect the hardness of the poured concrete. If the test is qualified, controller 27 starts vertical drive motor 37 to drive vertical transmission screw 25 to rotate inside vertical guide frame plate 26. Vertical transmission screw 25 drives threaded sleeve vertical block 24 to drive sleeve frame plate 23 to move upward under the action of the thread. Sleeve frame plate 23 drives transmission screw 20 to make second threaded sleeve support block 19 and first threaded sleeve support block 18 move upward at the same time. First threaded sleeve support block 18 and second threaded sleeve support block 19 respectively drive casting concave frame 15 and casting frame 16 to move upward. When sleeve frame plate 23 moves upward, it is sensed by distance sensor 28. When the sensed height is the height value set by controller 27, vertical drive motor 37 stops driving. After casting concave frame 15 and casting frame 16 are raised to the designated position, concrete pouring continues.

10. A construction method for a box-type bridge abutment transition structure, using the box-type bridge abutment transition structure as described in claim 9, characterized in that: The method includes the following steps: Step 1: First, drill bored piles. Based on the stress calculation and analysis of the box structure, drill bored piles are mainly installed on the outer wall and inner partition wall of the box to enhance the overall stress performance and resist load stress and strain. Step 2: Next, reinforce the pouring. Connect the reinforced pouring mechanism to the bridge abutment transition structure formed by the box-type bridge abutment and pour concrete into the joint to solidify and form the shape. Step 3: Then, pour concrete for the outer protection. After the protective components are formed to enclose the outer perimeter, pour the concrete and wait for it to solidify. Step 4: Finally, switch the detection. By switching the detection component, connect the hardness sensor (35) to the concrete that has been formed. After the qualified standard is met, lift the protective component to continue to stack and form the concrete. After the transition box is completed, cast-in-place reinforced concrete slabs are poured on the roadbed side. After the bridge deck leveling layer is completed, 100mm asphalt concrete pavement is carried out on the bridge deck and road surface. Finally, the expansion joints on the abutment side are installed.
