Description

Technical Field

[0001] The present application relates to the technical field of railway bridge engineering, and specifically to an assembled high-performance component used in railway bridge engineering and a production process thereof. Background Art

[0002] Railway bridges are structures built for railways to cross rivers, lakes, straits, valleys or other obstacles, and for realizing the three-dimensional intersection of railway lines with railway lines or roads. The components of railway bridges mainly include superstructures (bridge deck structures, main beams, etc.), piers and abutments, foundation structures, bearings, guardrails and safety facilities, drainage systems and additional facilities, etc. All parts work closely together to ensure that the bridge can safely and reliably carry the railway traffic load and maintain stability and durability during use.

[0003] As an important part of railway construction, the protective wall is not only related to the safety and stability of the railway line, but also closely related to the harmonious coexistence of the surrounding environment. It can effectively prevent debris and stones on the bridge deck from sliding down, protecting the railway and pedestrians below. At the same time, the protective wall can also isolate noise and reduce the impact on the surrounding environment and residents.

[0004] Regarding the above-mentioned related technologies, since the protective walls are arranged on both sides of the rails on the bridge deck, a U-shaped space is formed between the upper end surface of the bridge deck and the two protective walls. In rainy and snowy weather, snow and water are easily formed near the rails, which will cause the rails and various components on the bridge deck to be immersed in the accumulated water, which will accelerate the oxidation and corrosion of various components. Therefore, it is necessary to use a drainage system to discharge the accumulated water on the bridge deck in time. However, the drainage outlet of the drainage system on the bridge deck is generally easily blocked by fallen leaves and other debris, resulting in the entrance of the drainage outlet of the drainage system being blocked, which is not conducive to the timely discharge of accumulated water.

The outer side wall of the ordinary protection wall 2 is also provided with a splicing assembly including the first splicing block 12, the docking block 121, the second splicing block 13 and the docking groove 131. Among them, the docking block 121 on one wall is inserted into the docking groove 131 of the other wall, and the adjacent walls are assembled by splicing components, and multiple walls are assembled in sequence along the length direction of the bridge. The drainage trough group 15 is opened inside the drainage wall 11, and the drainage trough group 15 includes an air induced groove 151, a built-in groove 152 and a lower trough 153. The built-in groove 152 is opened inside the drainage wall 11 and close to the center. The air induced groove 151 is opened on the outer wall of the drainage wall 11 and close to the built-in groove 152, and one end of the air induced groove 151 passes through one side surface of the outer wall of the drainage wall 11, and the other end of the air induced groove 151 passes through the other side surface of the outer wall of the drainage wall 11. The contour of the inner wall of the air induced groove 151 is set as a structure formed by splicing two trapezoidal bodies, and the two trapezoidal bodies are symmetrically distributed about the built-in groove 152. The trapezoidal body is a quadrangular pyramid whose bottom and top surfaces are similar and whose side surfaces are all trapezoidal. The bottom area of ​​the quadrangular pyramid is larger than the top area, and the top surfaces of the two quadrangular pyramids overlap each other, and the overlapping top surfaces of the two quadrangular pyramids are located inside the drainage wall 11 and close to the center. The bottom surface of the quadrangular pyramid is opened on the outer wall of the drainage wall 11. The airflow can enter the interior of the drainage wall 11 from any notch of the air duct 151. The lower water trough 153 is opened on the lower end of the drainage wall 11 and on the side surface close to the railroad track, and the lower water trough 153 is opened at a position close to the bridge deck drain. The drainage auxiliary mechanism 4 is installed inside the drainage wall 11 and close to the lower water trough 153. An assembly groove 14 is provided on the upper end surface of the drainage wall 11 and near the center. An assembly groove 14 is also provided on the upper end surface of the common protective wall 2 and near the center. The assembly groove 14 provided on the drainage wall 11 has the same structure as the assembly groove 14 provided on the common protective wall 2. The detachable assembly barrier 3 is inserted into the assembly groove 14 from the upper end opening of the assembly groove 14. Two adjacent assembly barriers 3 are fixedly connected by bolts. The assembly barrier 3 can be selected to include assembled components such as protective nets and sound insulation boards.

[0035] The drainage wall 11 and the ordinary protective wall 2 are both prefabricated components for concrete pouring. When making the ordinary protective wall 2, the template 1 for pouring the protective wall is assembled at the pouring site, the concrete mixture for pouring the wall is filled into the template 1, and it is smoothed with a trowel. Before smoothing, a small vibrator can be used to vibrate appropriately. After pouring, the mold is removed after resting, and maintenance is carried out according to the corresponding maintenance system to obtain the prefabricated parts of the ordinary protective wall 2. Similarly, when making the drainage wall 11, the template 1 for pouring the wall is assembled at the pouring site, and the template 2 for opening each trough of the drainage trough group 15 is assembled at the same time. The template 2 is placed inside the template 1, and it is smoothed with a trowel. Before smoothing, a small vibrator can be used to vibrate appropriately. After pouring, the mold is removed after resting, and maintenance is carried out according to the corresponding maintenance system to obtain the prefabricated parts of the drainage wall 11, and then the drainage auxiliary mechanism 4 is installed in the drainage wall 11 to obtain the prefabricated parts of the drainage protective wall 1.

[0036] When paving the protective wall on the railway bridge, the prefabricated wall parts are transported to the designated installation position on the bridge deck by hoisting. According to the assembly requirements of the protective wall of the railway bridge, the ordinary protective wall 2 and the drainage protective wall 1 are placed in sequence, one of the walls is placed in the designated position first, and then the docking block 121 on the other wall is plugged into the docking groove 131 on the previous wall, so as to realize the serial splicing of adjacent walls, and then realize the serial connection of a row of walls. The drainage wall 11 is placed at the position where the drain is opened on the bridge deck, so that the drain trough 153 on the drainage wall 11 is docked with the drain on the bridge deck. After the protective wall is assembled, the assembly barrier 3 is plugged into the assembly groove 14 opened on the upper end face of the wall, and the adjacent assembly barriers 3 are fixedly connected by bolts. The drainage auxiliary mechanism 4 located inside the drainage wall 11 can improve the drainage effect of the drainage system of the bridge deck.

[0037] refer to Figure 2 , Figure 3 , Figures 5 to 8The drainage auxiliary mechanism 4 includes a main filter plate 41, a U-shaped plate 411, a bridging plate 412, a filter plate shaft 413, a traction hook 414, a traction rope 42, a limit rod 43, a driving shaft 44, a wind wheel 45 and a wind gathering component 46. An installation slot is provided inside the drainage wall 11 and near the lower water tank 153. The filter plate shaft 413 is inserted into one of the installation slots, and the main filter plate 41 is sleeved on the outside of the filter plate shaft 413. The main filter plate 41 is rotatably connected to the filter plate shaft 413, and the main filter plate 41 is rotatably connected to the drainage wall 11 through the filter plate shaft 413. The U-shaped plate 411 is fixedly mounted on the lower end of the main filter plate 41, and the concave surface of the U-shaped plate 411 faces upward. The U-shaped plate 411 is used to lift the debris attached to the outer wall of the main filter plate 41 to prevent the debris from falling. The strap 412 is fixedly mounted on one end of the U-shaped plate 411, and the strap 412 overlaps the bridge deck to prevent the main filter plate 41 from overturning. The traction hook 414 is fixedly mounted on the upper end of the main filter plate 41 and on a side surface facing the lower water tank 153. One end of the traction rope 42 is inserted into the mounting hole on the traction hook 414, and the other end of the traction rope 42 is inserted into the interior of the built-in through groove 152. The limit rod 43 is fixedly mounted inside the drainage wall 11 and close to the position of the traction rope 42, and the limit rod 43 is inserted into the mounting groove inside the drainage wall 11 and close to the position of the lower water tank 153. The installation height of the limit rod 43 is lower than the height of the traction hook 414, and the traction rope 42 passes through the lower water tank 153 from the bottom of the limit rod 43 and is inserted into the built-in through groove 152. The driving shaft 44 is installed inside the drainage wall 11 and close to the wind channel 151. The driving shaft 44 is installed inside the wind channel 151 and close to the center. The wind gathering component 46 is installed inside the drainage wall 11 and close to the driving shaft 44. The driving shaft 44 rotates inside the wind gathering component 46. One end of the traction rope 42 is inserted into the built-in through groove 152, passes through the built-in through groove 152, and then is inserted into the wind channel 151. One end of the traction rope 42 is inserted into the wind channel 151 and is fixedly connected to the driving shaft 44. The traction rope 42 is fixedly installed on the outside of the driving shaft 44 and close to the center. Two wind wheels 45 are sleeved on the outside of the driving shaft 44, and the two wind wheels 45 are symmetrically distributed about the traction rope 42. The wind wheel 45 is fixedly connected to the driving shaft 44 , and the wind wheel 45 drives the driving shaft 44 to rotate. When the driving shaft 44 rotates, the end of the traction rope 42 fixed to the driving shaft 44 is wound up, thereby achieving the purpose of tightening the traction rope 42 .

[0038] When the drainage protection wall 1 is prefabricated, the driving shaft 44 and the wind wheel 45 are installed between the two side plates 461 of the wind gathering component 46, and the traction rope 42 on the driving shaft 44 is extended from the through hole between the stabilizing plate 462 and the wind induction bottom plate 464. The wind gathering component 46 with the wind wheel 45 installed is embedded in the drainage wall 11 and close to the wind induction groove 151, so that the through hole between the stabilizing plate 462 and the wind induction bottom plate 464 is connected to the built-in groove 152 inside the drainage wall 11. One end of the traction rope 42 extends out of the wind gathering component 46 and passes through the built-in groove 152 and is inserted into the lower water tank 153. Insert the limiting rod 43 into the installation groove inside the drainage wall 11 and close to the lower water tank 153, pass the end of the traction rope 42 located in the lower water tank 153 from under the limiting rod 43, and then insert the traction rope 42 into the traction hook 414 at the upper end of the main filter plate 41, and finally install the main filter plate 41 at the opening of the lower water tank 153 through the filter plate rotating shaft 413, so that the main filter plate 41 is rotatably connected to the drainage wall 11.

[0039] Due to weather factors and train running, high-speed airflow will be formed on the bridge deck. When the drainage auxiliary mechanism 4 is working, the airflow formed by weather factors and train running can drive the wind wheel 45 to rotate after entering the drainage wall 11 from the slot at either end of the wind induced groove 151. Due to the structure of the wind induced groove 151, after the airflow enters the wind induced groove 151 from the slot at either end of the wind induced groove 151, the airflow speed at the wind wheel 45 is greater than the airflow speed at the entrance of the wind induced groove 151, thereby ensuring the rotation effect of the wind wheel 45. The airflow enters the interior of the drainage wall 11 from the slot of the wind induced groove 151. The high-speed flowing gas impacts the wind wheel 45, causing the wind wheel 45 to rotate, and the rotation of the wind wheel 45 drives the rotation of the driving shaft 44, and then the rotation of the driving shaft 44 winds up one end of the traction rope 42 fixed to the driving shaft 44, thereby achieving the purpose of tightening the traction rope 42. The other end of the traction rope 42 is used to pull the upper end of the main filter plate 41, so that the upper end of the main filter plate 41 is turned over to the inside of the lower water tank 153. At the same time, the end of the main filter plate 41 with the U-shaped plate 411 is turned over to the outside of the lower water tank 153. When water accumulates on the bridge deck and debris in the accumulated water accumulates at the position of the lower water tank 153, the main filter plate 41 can prevent the debris from entering the lower water tank 153, preventing the debris from blocking the bridge's water discharge channel. When too much debris accumulates at the main filter plate 41, the filter holes on the main filter plate 41 are blocked, resulting in a reduced discharge effect of the main filter plate 41. The main filter plate 41 is turned over by the rotation of the wind wheel 45, and the debris accumulated on the outside of the main filter plate 41 is lifted up to the outside of the lower water tank 153 by the U-shaped plate 411, and a channel for rapid discharge is opened between the U-shaped plate 411 and the bridge deck water outlet, and the water under the debris flows into the lower water tank 153 through the opening here, realizing the continuous discharge of accumulated water. When the air velocity inside the air duct 151 decreases, the force exerted by the air flow on the wind wheel 45 disappears, and the main filter plate 41 rotates back to the original position due to its own weight. When the main filter plate 41 rotates, it pulls the traction rope 42, so that the end of the traction rope 42 wound on the driving shaft 44 is unwound, and the wind wheel 45 rotates back to the original position. When the main filter plate 41 and the wind wheel 45 rotate back to the original position, the water channel between the U-shaped plate 411 and the bridge deck is closed, and the main filter plate 41 can continue to prevent debris outside the lower water tank 153 from entering the lower water tank 153.

[0040] refer to Figure 5 , Fig. 9 and Fig.10The wind gathering component 46 includes a side plate 461, a stabilizing plate 462, an air induction top plate 463, and an air induction bottom plate 464. The stabilizing plate 462 is fixedly installed between the two side plates 461, and the two side plates 461 are symmetrically distributed about the stabilizing plate 462. The lower end surface of the stabilizing plate 462 abuts against the inner wall of the drainage wall 11, and the outer wall of the side plate 461 abuts against the inner wall of the drainage wall 11. One end of the driving shaft 44 is inserted into the interior of one of the side plates 461, and the other end of the driving shaft 44 is inserted into the interior of the other side plate 461. The air induction top plate 463 is fixedly installed between the two side plates 461 and close to the upper end of the side plates 461. The air induction bottom plate 464 is fixedly installed between the two side plates 461 and close to the lower end of the side plates 461. A vent is provided between the draft top plate 463 and the stabilizing plate 462, and a vent is also provided between the draft bottom plate 464 and the draft top plate 463. The two vents are symmetrical about the center of the wind wheel 45, and the positions of the vents correspond to the concave surfaces of the blades of the wind wheel 45. A through hole is provided between the draft bottom plate 464 and the stabilizing plate 462 for the traction rope 42 to pass through.

[0041] The vent between the stabilizing plate 462 and the draft top plate 463 corresponds to the concave surface of the fan blade of the wind wheel 45, and the vent between the draft top plate 463 and the draft bottom plate 464 also corresponds to the concave surface of the fan blade of the wind wheel 45. The airflow passing through the draft slot 151 enters the range of the wind wheel 45 from the vent, and the airflow directly hits the concave surface of the fan blade of the wind wheel 45 after passing through the vent, further reducing the channel for the airflow to flow, accelerating the airflow, ensuring the force of the airflow blowing the wind wheel 45, and ensuring the normal flipping of the main filter plate 41.

[0042] A production process for assembled high-performance components used in railway bridge engineering, comprising the following steps:

[0043] S1. Material preparation: according to the performance requirements of the protective wall, prepare the concrete mixture for pouring the protective wall;

[0044] S2 template configuration, according to the size requirements of the protective wall, prepare a template for pouring the protective wall, according to the requirements of the grooves of each trough on the drainage wall 11, prepare a template for opening the drainage trough group 15;

[0045] S3. Prefabrication of ordinary protective wall 2, assembling a template for pouring the protective wall at the pouring site, filling the concrete mixture for pouring the wall into the template, smoothing it with a trowel, and vibrating it appropriately with a small vibrator before smoothing. After pouring, remove the mold after resting, and perform maintenance in accordance with the corresponding maintenance system to obtain a prefabricated part of the ordinary protective wall 2;

[0046] S4. Prefabrication of the drainage protection wall 1. Assemble the template 1 for pouring the wall at the pouring site, place the template 2 for opening each trough of the drainage trough group 15 inside the template 1, and smooth it with a trowel. Before smoothing, use a small vibrator to vibrate appropriately. After the pouring is completed, remove the mold after resting, and perform maintenance according to the corresponding maintenance system to obtain the prefabricated parts of the drainage wall 11, and install the drainage auxiliary mechanism 4 in the drainage wall 11.

[0047] The working principle of the embodiment of this application:

[0048] Prefabricated drainage wall 11 and ordinary protective wall 2, the prefabricated parts are transferred to the bridge deck of the railway bridge. When paving the protective wall on the railway bridge, one wall is first installed at the designated position on the bridge deck, and then the docking block 121 on the other wall is inserted into the docking groove 131 on the previous wall to complete the series connection of the protective walls.

[0049] During heavy rain, debris on the bridge deck gathers on the outside of the lower water tank 153 along with the water flow, and the main filter plate 41 blocks the debris to prevent it from entering the lower water channel of the bridge deck. The airflow formed by weather factors and train running flows into the interior of the drainage wall 11 from the notches at either end of the wind induced groove 151, and the airflow flows at a high speed inside the wind induced groove 151, and enters the rotation range of the wind wheel 45 after passing through the vent. The high-speed airflow directly impacts the concave surface of the fan blades of the wind wheel 45, driving the wind wheel 45 to rotate rapidly, so that the driving shaft 44 winds up one end of the traction rope 42 fixed to the driving shaft 44, thereby tightening the traction rope 42, and the other end of the traction rope 42 pulls the traction hook 414 on the main filter plate 41, so that the upper end of the main filter plate 41 turns over to the inside of the lower water tank 153, and at the same time, the lower end of the main filter plate 41 turns over to the outside of the lower water tank 153. The debris accumulated on the outside of the main filter plate 41 is pushed by the raised U-shaped plate 411, and a gap is opened between the U-shaped plate 411 and the bridge deck, which is only for the accumulated water to pass through, so as to ensure the normal discharge of the accumulated water on the bridge deck. The airflow intermittently flows into the air induction groove 151, so that the main filter plate 41 is intermittently turned over, so that the main filter plate 41 intermittently moves the debris accumulated on the outside of the lower water tank 153, and vacates a channel for the accumulated water to pass through, so as to ensure the drainage effect.
