Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge engineering, in particular to a bridge large-width box girder linear control device and method based on visual technology. BACKGROUND

[0002] The bridge large-width box girder linear control device is a device for ensuring that the linear shape of the bridge large-width box girder meets the design requirements during construction and use.

[0003] Most of the existing devices control the linear shape of the bridge large-width box girder by using prestressed anchoring, centering locking, water tank counterweight, and bed-jig adjustment. Although these devices can limit the linear shape change of the bridge large-width box girder to a certain extent, the existing devices are measures taken after the concrete on the side of the bridge large-width box girder is solidified or is about to be solidified and formed, and lack the function of controlling the linear shape change during pouring. There is a certain functional gap. In order to control the linear shape change of the bridge large-width box girder during construction, most of the existing devices embed circulating cooling water pipes in the areas where hydration heat is easy to accumulate, such as the wide end and the web. However, most of the circulating water pipes are directly poured into the concrete and cannot be taken out, which may increase the construction cost and cause waste of materials. Embedding circulating cooling water pipes may also affect the overall stability of the building, thereby increasing the difficulty of controlling the linear shape of the bridge large-width box girder. Therefore, the present application provides a bridge large-width box girder linear control device and method based on visual technology to meet the needs. SUMMARY

[0014] A method for controlling the alignment of a bridge box girder with large width variation based on vision technology includes the following steps: Step 1: When using this device, the construction worker needs to determine the width of the bridge's wide-section box girder based on the drawings. After confirming the dimensions, the large cylinders on both sides of the middle section formwork are activated. The large cylinders will push the side stress relief modules on both sides of the middle section formwork towards the middle part of the middle section formwork. When the side stress relief modules on the left and right sides of the middle section formwork reach the ideal position, the operation of the large cylinders needs to be stopped. At this time, the front and back of the side stress relief modules on the left and right sides of the middle section formwork need to be sealed manually using the existing formwork or aluminum formwork. In this way, the concrete can be poured into the gap between the side stress relief modules on the left and right sides of the middle section formwork. The monitoring camera is responsible for monitoring the movement of the large cylinder support, thereby monitoring stress changes to a certain extent through visual technology. During concrete pouring, the side stress relief module is responsible for vibrating the concrete on its sides using the impact force of high-pressure water. The low temperature of the high-pressure water removes the high temperature heat generated by the hydrothermal transformation of the concrete on its sides. The side stress relief module mainly disperses and relieves the stress in the concrete during the pouring process. The internal cooling module mainly replaces the traditional pre-embedded circulating water cooling pipe to cool the concrete that has just been poured. It can be removed in time when not needed, so as not to be poured into the concrete, thereby reducing material waste and protecting the stability of the main structure. It should be noted that after the side stress relief module is moved to the ideal position, the filling block needs to be placed on the top of the filling block seat plate to fill the excess groove, so as to prevent concrete from being poured into the excess groove, which would cause the excess groove to be filled and make the side stress relief module unable to move and work in the later stage. Step 2: When the concrete pouring begins, a large water pump needs to be started. After the large water pump is started, it will use negative pressure to draw water from the first water tank into the large water pump for exchange. The water is then transmitted through the first water delivery pipe to the first threaded end. Then, the high-pressure water passes through the second threaded end into the high-pressure nozzle and is finally sprayed onto the inner box. The high-pressure water sprayed onto the inner box will generate a certain vibration force. This vibration force will vibrate the concrete on the outer side of the inner box without dead angles. This is better than manual vibration. Manual vibration will vibrate at intervals and mostly vibrate the middle of the concrete, while the sides are hardly vibrated. Therefore, after manual vibration, the sides of the building are very likely to have pitted surfaces. The impact force of the high-pressure water sprayed from the high-pressure nozzle can cover almost all the positions on the inner side of the inner box. Therefore, its vibration force has a better vibration effect on the concrete on the outer side of the inner box. The high-pressure water sprayed from the high-pressure nozzle is also at a lower temperature. After the concrete on the outer side of the inner box undergoes hydration heat, the heat generated can be carried away by the high-pressure water sprayed from the high-pressure nozzle. This reduces the heat generated by the concrete on the outer side of the inner box and reduces its stress, thereby limiting the occurrence of stress to a certain extent. When the side stress relief module is pushed by the large cylinder, it mainly moves on the track bar through the track wheel base and track wheel. The sprayed high-pressure water will enter the first return water pipe through the water inlet and then flow back to the first water tank. Step 3: After part of the concrete is poured, although the concrete has not yet solidified, a hydration heat reaction has begun inside, and the internal temperature of the concrete gradually increases, causing the concrete to expand and linear stress to appear. At this time, the worker needs to unscrew the connecting bolts in time, and then manually flip the square horizontal plate from vertical to horizontal. When the square horizontal plate is flipped to the horizontal position, the bottom of the square horizontal plate will be exactly on the top of the right angle plate. The right angle plate provides some support for the square horizontal plate. When the square horizontal plate is flipped to the horizontal position, the worker needs to start the small cylinder to drive the hollow column to move up and down. The small water pump needs to be started manually at the same time. At this time, the small water pump sends the water in the second water tank to the hollow column through the second water delivery pipe. As the hollow column moves upward, the hollow disc on it separates from the circular sealing plate. The cooler water stored in the hollow column is released from it. Because the water used to cool the concrete has already been heated by the hydrothermal reaction, the temperature difference between the released water and the water is significant. The newly released water moves downward, while the warmer water is pushed upward by the newly released water. As the hollow column moves downward, it is pushed upward by the extremely high pressure and squeezed out from the sixth threaded end. It then passes through the one-way valve into the second return water pipe. Because the small cylinder does not stop after starting, it continuously drives the hollow column to move up and down, causing the warmer water to be continuously squeezed out. This allows all the water in the second return water pipe to flow back into the second water tank without any other auxiliary transmission equipment. Meanwhile, the water newly entering the hollow column will cool and exchange heat for the high temperature generated by the hydrothermal reaction of the concrete.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a side stress compensation module, the device can remove the heat generated by the hydration heat of the concrete on the side of the bridge's wide-gauge box girder during concrete pouring through the squeezing force of the inner box, the vibration force of the high-pressure water impact on the inner box, and the low temperature of the water. This minimizes the outward expansion stress of the concrete during pouring. At the same time, the vibration force can compact the side concrete without distance. To a certain extent, this device can not only reduce the possibility of changes in the alignment of the concrete on the side of the bridge's wide-gauge box girder, but also make up for the lack of control over alignment changes in existing devices during pouring, thus filling the functional gaps of existing devices to a certain extent.

[0016] By incorporating an internal cooling module, the device can cool the concrete while it is being poured, thereby controlling the generation of massive amounts of hydration heat. This, in turn, minimizes the impact of hydration heat on the alignment of the bridge's widened box girder. Furthermore, the module can be removed after cooling, allowing it to be reused multiple times. This reduces construction costs and material waste, decreases the probability of the circulating water pipes being directly poured into the concrete potentially affecting the overall stability of the structure, and further reduces the difficulty of controlling the alignment of the bridge's widened box girder.

[0026] like Figures 1 to 5As shown, an embodiment of the present invention provides a bridge widening box girder alignment control device and method based on vision technology, including a middle section template 1, a cylinder base 2 on the side of the middle section template 1, a groove on the top of the middle section template 1 and the cylinder base 2, a filling block top plate 3 fixedly connected to the inner wall of the groove, a filling block 4 on the top of the filling block top plate 3, a track base 5 fixedly connected to the bottom of the groove, a track bar 6 fixedly connected to the bottom of the track base 5, a monitoring camera 7 and a large cylinder 8 arranged sequentially from front to back on the top of the cylinder base 2, both the monitoring camera 7 and the large cylinder 8 are threadedly connected to the cylinder base 2 by cylinder base bolts, a side stress relief module 9 is provided at one end of the large cylinder 8, an internal cooling module 10 is provided at the top of the side stress relief module 9, and a column 11 is provided at the bottom of both the middle section template 1 and the cylinder base 2.

[0027] The cylinder base 2 is welded to both sides of the middle section template 1. The grooves are integrally formed with the middle section template 1 and the cylinder base 2. The top plate 3 of the filling block is welded to the inner wall of the groove. The track base 5 and the track bar 6 are integrally formed. The track base 5 is welded to the bottom of the groove so that the track bar 6 is placed in the groove. The monitoring camera 7 and the large cylinder 8 are installed on the cylinder base 2 by cylinder base bolts. The side stress relief module 9 is installed on the cylinder rod of the large cylinder 8. The internal cooling module 10 is installed on the top of the side stress relief module 9. The column 11 is welded to the bottom of the middle section template 1 and the cylinder base 2.

[0028] When using this device, the construction worker needs to determine the width of the bridge's wide-gauge box girder based on the drawings. After confirming the dimensions, the large cylinders 8 on both sides of the middle section template 1 are activated. The large cylinders 8 will push the side stress relief modules 9 on both sides of the middle section template 1 towards the middle part of the middle section template 1. When the side stress relief modules 9 on the left and right sides of the middle section template 1 reach the ideal position, the operation of the large cylinders 8 needs to be stopped. At this time, the front and back of the side stress relief modules 9 on the left and right sides of the middle section template 1 need to be sealed manually using the existing templates or aluminum templates. In this way, the concrete can be poured into the gap between the side stress relief modules 9 on the left and right sides of the middle section template 1. The monitoring camera 7 is responsible for monitoring the support movement of the large cylinders 8, thereby monitoring stress changes to a certain extent through visual technology. During concrete pouring, the side stress relief module 9 is responsible for vibrating the concrete on its sides using the impact force of high-pressure water. The low temperature of the high-pressure water removes the high temperature heat generated by the hydrothermal transformation of the concrete on its sides. The side stress relief module 9 mainly disperses and relieves the stress in the concrete during the pouring process. The internal cooling module 10 mainly replaces the traditional pre-embedded circulating water cooling pipe to cool the freshly poured concrete. It can be removed in time when not needed, without pouring it into the concrete, thereby reducing material waste and protecting the stability of the main structure. It should be noted that after the side stress relief module 9 is moved to the ideal position, the filling block 4 needs to be placed on top of the filling block top plate 3 to fill the excess groove, preventing concrete from being poured into the excess groove, which would cause the excess groove to be filled and make the side stress relief module 9 unable to move and work in the later stage.

[0029] like Figures 6 to 10 As shown, in this embodiment, the side stress relief module 9 includes a first water tank 901. An L-shaped water injection connection end 902 is fixedly connected to the front of the first water tank 901. A first circular hole is opened on one side of the first water tank 901. A large water pump 903 is installed inside the first circular hole. The large water pump 903 is threadedly connected to the first water tank 901 through a large water pump bolt. A first water delivery pipe 904 is threadedly connected to one end of the large water pump 903. A first threaded end 905 is threadedly connected to one end of the first water delivery pipe 904. A first hollow connecting circular plate 906 is fixedly connected to one end of the first threaded end 905. A large cylinder 8 is threadedly connected to the first water tank 901 through a large cylinder bolt.

[0030] A second threaded end 907 is fixedly connected to one end of the first hollow connecting circular plate 906. A high-pressure nozzle 908 is threadedly connected to the surface of the second threaded end 907. A side plate 909 is threadedly connected to the first hollow connecting circular plate 906 via a first hollow connecting circular plate bolt. A second circular hole and a third circular hole are sequentially opened on one side of the side plate 909 from front to back. The second circular hole and the second threaded end 907 are mutually adapted. A water inlet end 910 is provided inside the third circular hole. A second hollow connecting circular plate 911 is fixedly connected to one end of the water inlet end 910. A third threaded end 912 is fixedly connected to one end of the second hollow connecting circular plate 911. The side plate 909 is threadedly connected to the second hollow connecting circular plate 911 via a second hollow connecting circular plate bolt.

[0031] The surface of the third threaded end 912 is threadedly connected to the first return water pipe 913. The third threaded end 912 is threadedly connected to the fourth threaded end 914 through the first return water pipe 913. One end of the fourth threaded end 914 is fixedly connected to the first water tank 901. One side of the side plate 909 is fixedly connected to the inner box 915. One side of the first water tank 901 is fixedly connected to the straight plate 916. The bottom of the straight plate 916 is fixedly connected to the track wheel base 917. The front of the track wheel base 917 is provided with a track wheel rotation hole, and a track wheel 918 is provided inside the track wheel rotation hole.

[0032] Weld the L-shaped water injection connector 902 to the front of the first water tank 901. Insert the large water pump 903 through the first circular hole into the first water tank 901, and then install it onto the first water tank 901 using large water pump bolts. Install the first water delivery pipe 904 between the large water pump 903 and the first threaded end 905. The first threaded end 905, the first hollow connecting plate 906, and the second threaded end 907 are integrally connected. Install the first hollow connecting plate 906 onto the side plate 909 using first hollow connecting plate bolts. Install the high-pressure nozzle 908 onto the second threaded end 907. The side plate 909 and the inner box 915 are welded together. The water inlet end 910, the second hollow connecting round plate 911 and the third threaded end 912 are integrally connected. The second hollow connecting round plate 911 is installed on the side plate 909 by the second hollow connecting round plate bolt. The first return water pipe 913 is installed between the third threaded end 912 and the fourth threaded end 914. The straight plate 916 is welded between the first water tank 901 and the side plate 909. The track wheel base 917 is welded to the bottom of the straight plate 916. Finally, the track wheel 918 is installed into the track wheel rotating hole on the track wheel base 917.

[0033] When concrete pouring begins, a large water pump 903 needs to be started. After the large water pump 903 is started, it will use negative pressure to draw water from the first water tank 901 into the large water pump 903 for exchange. The water is then transmitted to the first threaded end 905 through the first water delivery pipe 904. Then, the high-pressure water passes through the second threaded end 907 and enters the high-pressure nozzle 908. Finally, the high-pressure nozzle 908 sprays the water onto the inner box 915. The high-pressure water sprayed onto the inner box 915 will generate a certain vibration force. This vibration force will vibrate the concrete on the outer surface of the inner box 915 without dead angles. This is better than manual vibration. Manual vibration will vibrate at intervals, and most of the vibration will only reach the middle of the concrete. The sides will hardly be vibrated. Therefore, after manual vibration, the sides of the building are very likely to have pitted surfaces. The impact force of the high-pressure water sprayed from the high-pressure nozzle 908 can cover almost all the inner sides of the inner box 915. Therefore, its vibration force has a better vibration effect on the concrete on the outer side of the inner box 915. The high-pressure water sprayed by the high-pressure nozzle 908 is also at a lower temperature. After the concrete on the outer side of the inner box 915 undergoes hydration heat, the heat generated can be carried away by the high-pressure water sprayed by the high-pressure nozzle 908. This reduces the heat generated by the concrete on the outer side of the inner box 915, and the stress effect will be reduced, thereby limiting the occurrence of stress to a certain extent. When the side stress relief module 9 is pushed by the large cylinder 8, it mainly moves on the track bar 6 through the track wheel base 917 and track wheel 918. The sprayed high-pressure water will enter the first return water pipe 913 through the water inlet 910 and then flow back to the first water tank 901.

[0034] By incorporating the side stress relief module 9, the device can utilize the squeezing pressure of the inner box 915, the vibration force of the high-pressure water impact on the inner box 915, and the low temperature of the water during concrete pouring. This helps to remove the heat generated by the hydration heat of the concrete on the side of the bridge's wide-gauge box girder, thereby minimizing the outward expansion stress of the concrete during pouring. Simultaneously, the vibration force can compact the side concrete without any distance. To a certain extent, this device can not only reduce the possibility of changes in the alignment of the concrete on the side of the bridge's wide-gauge box girder, but also compensate for the lack of control over alignment changes in existing devices during pouring, thus filling a functional gap in existing devices to some extent.

A one-way valve 1021 is threadedly connected to the surface of the sixth threaded end 1020.

[0039] One end of the one-way valve 1021 is threadedly connected to a second return water pipe 1022. One end of the second return water pipe 1022 is threadedly connected to a seventh threaded end 1023. One end of the seventh threaded end 1023 is fixedly connected to a second water tank 1024. A straight water inlet end 1025 is fixedly connected to the top of the second water tank 1024. A sixth circular hole is opened on one side of the second water tank 1024. A small water pump 1014 is installed inside the sixth circular hole. The small water pump 1014 is threadedly connected to the second water tank 1024 through a small water pump bolt.

[0040] The base plate 1001 and the square column 1002 are welded together. The right-angle plate 1003 is welded to the square column 1002.

[0041] After part of the concrete is poured, although the concrete has not yet solidified, a hydration heat reaction has begun to occur inside it. The temperature inside the concrete gradually rises, causing the concrete to expand and linear stress to appear. At this time, the worker needs to unscrew the connecting bolt 1008 in time and then manually flip the square horizontal plate 1005 from vertical to horizontal. When the square horizontal plate 1005 is flipped to the horizontal position, the bottom of the square horizontal plate 1005 will be exactly on the top of the right angle plate 1003. The right angle plate 1003 provides some support for the square horizontal plate 1005. When the square horizontal plate 1005 is flipped to the horizontal position, the worker needs to start the small cylinder 1007. The small cylinder 1007 drives the hollow thin column 1010 to move up and down. The small water pump 1014 needs to be started manually at the same time. At this time, the small water pump 1014 sends the water in the second water tank 1024 to the hollow thin column 1010 through the second water delivery pipe 1013. As the hollow column 1010 moves upward, the hollow disc 1011 on the hollow column 1010 separates from the circular sealing plate 1019. The cooler water stored in the hollow column 1010 is released from within. Because the water previously used to cool the concrete has already increased in temperature due to hydrothermal action, the temperature difference between the released water and the warmer water is significant. The newly released water moves downward, while the warmer water is pushed upward by the newly released water. As the hollow column 1010 moves downward, it is further compressed upward by the extremely high pressure, and the water flows out from the... The water is squeezed out from the six-threaded end 1020 and then passes through the one-way valve 1021 into the second return water pipe 1022. Because the small cylinder 1007 does not stop after starting, it will continuously drive the hollow thin column 1010 to move up and down, which will cause the high-temperature water to be squeezed out continuously. As a result, the water in the second return water pipe 1022 can return to the second water tank 1024 without other auxiliary transmission equipment. The water newly entering the hollow thick column 1017 will cool down and exchange heat for the high temperature generated by the hydrothermal reaction of concrete.

[0042] By incorporating an internal cooling module 10, the device can cool the concrete while it is being poured, thereby controlling the generation of massive amounts of hydration heat and minimizing its impact on the shape changes of the bridge's widened box girder. Furthermore, the module can be removed after cooling, allowing it to be reused multiple times. This reduces construction costs and material waste, decreases the probability of the circulating water pipes being directly poured into the concrete affecting the overall stability of the structure, and further reduces the difficulty of controlling the shape of the bridge's widened box girder.

[0043] A method for controlling the alignment of a bridge box girder with large width variation based on vision technology includes the following steps: Step 1: When using this device, the construction worker needs to determine the width of the bridge's wide-gauge box girder based on the drawings. After confirming the dimensions, the large cylinders 8 on both sides of the middle section template 1 are activated. The large cylinders 8 will push the side stress relief modules 9 on both sides of the middle section template 1 towards the middle part of the middle section template 1. When the side stress relief modules 9 on the left and right sides of the middle section template 1 reach the ideal position, the operation of the large cylinders 8 needs to be stopped. At this time, the front and back of the side stress relief modules 9 on the left and right sides of the middle section template 1 need to be sealed manually using the existing templates or aluminum templates. In this way, the concrete can be poured to the gap between the side stress relief modules 9 on the left and right sides of the middle section template 1. The monitoring camera 7 is responsible for monitoring the support movement of the large cylinders 8, thereby monitoring stress changes to a certain extent through visual technology. During concrete pouring, the side stress relief module 9 is responsible for vibrating the side concrete using the impact force of high-pressure water. The low temperature of the high-pressure water carries away the high temperature heat generated by the hydrothermal transformation of the side concrete. The side stress relief module 9 mainly disperses and relieves the stress of the concrete during the concrete pouring process. The internal cooling module 10 mainly replaces the traditional pre-embedded circulating water cooling pipe to cool the freshly poured concrete. It can be removed in time when not needed, without pouring it into the concrete, thereby reducing material waste and protecting the stability of the main body. It should be noted that after the side stress relief module 9 is moved to the ideal position, the filling block 4 needs to be placed on the top of the filling block top plate 3 to fill the excess groove and prevent concrete from being poured into the excess groove, which would cause the excess groove to be filled and make the side stress relief module 9 unable to continue to move and work. Step Two: When concrete pouring begins, the large water pump 903 needs to be started. After starting, the large water pump 903 will use negative pressure to draw water from the first water tank 901 into the large water pump 903 for exchange. The water is then transmitted through the first water delivery pipe 904 to the first threaded end 905. Then, the high-pressure water passes through the second threaded end 907 into the high-pressure nozzle 908, and is finally sprayed onto the inner tank 915 by the high-pressure nozzle 908. The high-pressure water sprayed onto the inner tank 915 will generate a certain vibration force. Its vibration force will vibrate the concrete on the outer side of the inner box 915 without dead angles. This is better than manual vibration. Manual vibration will vibrate at intervals, and most of the vibration will only vibrate the middle part of the concrete, and the sides will hardly be vibrated. Therefore, after manual vibration, the side of the building is very likely to have pitted surface. The impact force of the high pressure water sprayed by the high pressure nozzle 908 can almost cover all the positions of the inner side of the inner box 915. Therefore, its vibration force has a better vibration effect on the concrete on the outer side of the inner box 915. The high-pressure water sprayed by the high-pressure nozzle 908 is also at a lower temperature. After the concrete on the outer side of the inner box 915 undergoes hydration heat, the heat generated can be carried away by the high-pressure water sprayed by the high-pressure nozzle 908. This reduces the heat generated by the concrete on the outer side of the inner box 915, and the stress effect will be reduced, thereby limiting the occurrence of stress to a certain extent. When the side stress relief module 9 is pushed by the large cylinder 8, it mainly moves on the track bar 6 through the track wheel base 917 and track wheel 918. The sprayed high-pressure water will enter the first return water pipe 913 through the water inlet 910 and then flow back to the first water tank 901. Step 3: After part of the concrete is poured, although the concrete has not yet solidified, a hydration heat reaction has begun inside, and the internal temperature of the concrete gradually increases, causing the concrete to expand and linear stress to appear. At this time, the worker needs to unscrew the connecting bolt 1008 in time, and then manually flip the square horizontal plate 1005 from vertical to horizontal. When the square horizontal plate 1005 is flipped to the horizontal position, the bottom of the square horizontal plate 1005 will be exactly on the top of the right angle plate 1003. The right angle plate 1003 provides a certain support for the square horizontal plate 1005. When the square horizontal plate 1005 is flipped to the horizontal position, the worker needs to start the small cylinder 1007. The small cylinder 1007 drives the hollow thin column 1010 to move up and down. The small water pump 1014 needs to be started manually at the same time. At this time, the small water pump 1014 sends the water in the second water tank 1024 to the hollow thin column 1010 through the second water delivery pipe 1013. As the hollow column 1010 moves upward, the hollow disc 1011 on the hollow column 1010 separates from the circular sealing plate 1019. The cooler water stored in the hollow column 1010 is released from within. Because the water previously used to cool the concrete has already increased in temperature due to hydrothermal action, the temperature difference between the released water and the warmer water is significant. The newly released water moves downward, while the warmer water is pushed upward by the newly released water. As the hollow column 1010 moves downward, it is further compressed upward by the extremely high pressure, and the water flows out from the... The water is squeezed out from the six-threaded end 1020 and then passes through the one-way valve 1021 into the second return water pipe 1022. Because the small cylinder 1007 does not stop after starting, it will continuously drive the hollow thin column 1010 to move up and down, which will cause the high-temperature water to be squeezed out continuously. As a result, the water in the second return water pipe 1022 can return to the second water tank 1024 without other auxiliary transmission equipment. The water newly entering the hollow thick column 1017 will cool down and exchange heat for the high temperature generated by the hydrothermal reaction of concrete.

[0044] The working principle of the technical solution provided by this invention is as follows: When using this device, the construction worker needs to determine the width of the bridge's wide-gauge box girder based on the drawings. After confirming the dimensional data, the large cylinders 8 on both sides of the middle section template 1 are activated. The large cylinders 8 work, pushing the side stress relief modules 9 on both sides of the middle section template 1 towards the middle part of the middle section template 1. When the side stress relief modules 9 on the left and right sides of the middle section template 1 reach the ideal position, the work of the large cylinders 8 needs to be stopped. At this time, it is necessary to manually use existing templates or aluminum templates to seal the front and back of the side stress relief modules 9 on the left and right sides of the middle section template 1. In this way, concrete can be poured to the side stress relief modules on the left and right sides of the middle section template 1. At the gap between positions 9, monitoring camera 7 monitors the movement of the large cylinder 8 support, thereby monitoring stress changes to a certain extent through visual technology. During concrete pouring, the side stress relief module 9 uses the impact force of high-pressure water to vibrate the concrete on its sides. The low temperature of the high-pressure water removes the high temperature heat generated by the hydrothermal transformation of the concrete on its sides. The side stress relief module 9 mainly disperses and relieves the stress in the concrete during the pouring process. The internal cooling module 10 mainly replaces the traditional pre-embedded circulating water cooling pipe to cool the freshly poured concrete. It can be removed in time when not needed, without being poured into the concrete, thereby reducing material waste and protecting the stability of the main structure. When the concrete pouring begins... At this point, the large water pump 903 needs to be started. After the large water pump 903 starts, it will use negative pressure to draw water from the first water tank 901 into the large water pump 903 for exchange. The water is then transmitted through the first water delivery pipe 904 to the first threaded end 905. Then, the high-pressure water passes through the second threaded end 907 and enters the high-pressure nozzle 908. Finally, the high-pressure nozzle 908 sprays the water onto the inner box 915. The high-pressure water sprayed onto the inner box 915 will generate a certain vibration force. This vibration force will vibrate the concrete on the outer surface of the inner box 915 without dead angles. The advantage of this over manual vibration is that manual vibration is only performed at intervals, and most of the vibration is only in the middle of the concrete, with almost no vibration on the sides. Therefore, after manual vibration, the sides of the building will be more effectively vibrated. It is highly likely that pitted surfaces will appear. However, the impact force of the high-pressure water sprayed by the high-pressure nozzle 908 can almost cover all parts of the inner side of the inner box 915. Therefore, its vibration force has a better vibration effect on the concrete on the outer side of the inner box 915. The temperature of the high-pressure water sprayed by the high-pressure nozzle 908 is also lower. After the concrete on the outer side of the inner box 915 undergoes hydration heat, the heat generated can be carried away by the high-pressure water sprayed by the high-pressure nozzle 908. This reduces the heat generated on the outer side of the inner box 915, and the stress will be reduced, thus limiting the occurrence of stress to a certain extent. When the side stress relief module 9 is pushed by the large cylinder 8, it mainly moves on the track bar 6 through the track wheel base 917 and track wheel 918.The sprayed high-pressure water enters the first return water pipe 913 through the inlet 910 and then flows back to the first water tank 901. After part of the concrete is poured, although the concrete has not yet solidified, a hydration heat reaction has begun inside, causing the internal temperature of the concrete to gradually rise, leading to expansion and the appearance of linear stress. At this time, the worker needs to unscrew the connecting bolts 1008 and then manually flip the square transverse plate 1005 from vertical to horizontal. When the square transverse plate 1005 is flipped to the horizontal position, the square transverse plate... The bottom of plate 1005 will be exactly at the top of right-angle plate 1003. Right-angle plate 1003 provides some support for square horizontal plate 1005. When square horizontal plate 1005 is flipped to become horizontal, the worker needs to start small cylinder 1007. Small cylinder 1007 drives hollow thin column 1010 to move up and down. Small water pump 1014 needs to be started manually at the same time. At this time, small water pump 1014 sends water from second water tank 1024 to hollow thin column 1010 through second water delivery pipe 1013. When hollow thin column 1010 moves towards... During upward movement, the hollow disc 1011 on the hollow column 1010 separates from the circular sealing plate 1019. The cooler water stored in the hollow column 1010 is released from within. Because the water previously used to cool the concrete has already increased in temperature due to hydrothermal action, the temperature difference between the released water and the warmer water is significant. The newly released water moves downwards, while the warmer water is pushed upwards by the newly released water. As the hollow column 1010 moves downwards, it is further pushed upwards by the extremely high compressive force and exits from the sixth threaded end 1. The water is squeezed out from the hollow column 1010 and then passes through the one-way valve 1021 into the second return water pipe 1022. Because the small cylinder 1007 does not stop after starting, it continuously drives the hollow thin column 1010 to move up and down, causing the high-temperature water to be continuously squeezed out. This allows all the water in the second return water pipe 1022 to flow back to the second water tank 1024 without any other auxiliary transmission equipment. Meanwhile, the water newly entering the hollow thick column 1017 will cool and exchange heat for the high temperature generated by the hydrothermal reaction of the concrete.

10. The method for controlling the alignment of a bridge box girder with large width variation based on vision technology according to claim 1, characterized in that, Includes the following steps: Step 1: When using this device, the construction worker needs to determine the width of the bridge's wide-section box girder based on the drawings. After confirming the dimensions, the large cylinders on both sides of the middle section formwork are activated. The large cylinders will push the side stress relief modules on both sides of the middle section formwork towards the middle part of the middle section formwork. When the side stress relief modules on the left and right sides of the middle section formwork reach the ideal position, the operation of the large cylinders needs to be stopped. At this time, the front and back of the side stress relief modules on the left and right sides of the middle section formwork need to be sealed manually using the existing formwork or aluminum formwork. In this way, the concrete can be poured into the gap between the side stress relief modules on the left and right sides of the middle section formwork. The monitoring camera is responsible for monitoring the movement of the large cylinder support, thereby monitoring stress changes to a certain extent through visual technology. During concrete pouring, the side stress relief module is responsible for vibrating the concrete on its sides using the impact force of high-pressure water. The low temperature of the high-pressure water removes the high temperature heat generated by the hydrothermal transformation of the concrete on its sides. The side stress relief module mainly disperses and relieves the stress in the concrete during the pouring process. The internal cooling module mainly replaces the traditional pre-embedded circulating water cooling pipe to cool the concrete that has just been poured. It can be removed in time when not needed, so as not to be poured into the concrete, thereby reducing material waste and protecting the stability of the main structure. It should be noted that after the side stress relief module is moved to the ideal position, the filling block needs to be placed on the top of the filling block seat plate to fill the excess groove, so as to prevent concrete from being poured into the excess groove, which would cause the excess groove to be filled and make the side stress relief module unable to move and work in the later stage. Step 2: When the concrete pouring begins, a large water pump needs to be started. After the large water pump is started, it will use negative pressure to draw water from the first water tank into the large water pump for exchange. The water is then transmitted through the first water delivery pipe to the first threaded end. Then, the high-pressure water passes through the second threaded end into the high-pressure nozzle and is finally sprayed onto the inner box. The high-pressure water sprayed onto the inner box will generate a certain vibration force. This vibration force will vibrate the concrete on the outer side of the inner box without dead angles. This is better than manual vibration. Manual vibration will vibrate at intervals and mostly vibrate the middle of the concrete, while the sides are hardly vibrated. Therefore, after manual vibration, the sides of the building are very likely to have pitted surfaces. The impact force of the high-pressure water sprayed from the high-pressure nozzle can cover almost all the positions on the inner side of the inner box. Therefore, its vibration force has a better vibration effect on the concrete on the outer side of the inner box. The high-pressure water sprayed from the high-pressure nozzle is also at a lower temperature. After the concrete on the outer side of the inner box undergoes hydration heat, the heat generated can be carried away by the high-pressure water sprayed from the high-pressure nozzle. This reduces the heat generated by the concrete on the outer side of the inner box and reduces its stress, thereby limiting the occurrence of stress to a certain extent. When the side stress relief module is pushed by the large cylinder, it mainly moves on the track bar through the track wheel base and track wheel. The sprayed high-pressure water will enter the first return water pipe through the water inlet and then flow back to the first water tank. Step 3: After part of the concrete is poured, although the concrete has not yet solidified, a hydration heat reaction has begun inside, and the internal temperature of the concrete gradually increases, causing the concrete to expand and linear stress to appear. At this time, the worker needs to unscrew the connecting bolts in time, and then manually flip the square horizontal plate from vertical to horizontal. When the square horizontal plate is flipped to the horizontal position, the bottom of the square horizontal plate will be exactly on the top of the right angle plate. The right angle plate provides some support for the square horizontal plate. When the square horizontal plate is flipped to the horizontal position, the worker needs to start the small cylinder to drive the hollow column to move up and down. The small water pump needs to be started manually at the same time. At this time, the small water pump sends the water in the second water tank to the hollow column through the second water delivery pipe. As the hollow column moves upward, the hollow disc on it separates from the circular sealing plate. The cooler water stored in the hollow column is released from it. Because the water used to cool the concrete has already been heated by the hydrothermal reaction, the temperature difference between the released water and the water is significant. The newly released water moves downward, while the warmer water is pushed upward by the newly released water. As the hollow column moves downward, it is pushed upward by the extremely high pressure and squeezed out from the sixth threaded end. It then passes through the one-way valve into the second return water pipe. Because the small cylinder does not stop after starting, it continuously drives the hollow column to move up and down, causing the warmer water to be continuously squeezed out. This allows all the water in the second return water pipe to flow back into the second water tank without any other auxiliary transmission equipment. Meanwhile, the water newly entering the hollow column will cool and exchange heat for the high temperature generated by the hydrothermal reaction of the concrete.
