Background Art

[0002] With the continuous development of modern technology, the maintenance and management of hollow, thin-walled bridge piers is an important component of bridge construction and maintenance, and a crucial means of preventing cracking and ensuring durability. With the continuous increase in highway mileage, the practice of "cutting through mountains and building bridges over rivers" has become the norm, leading to a sharp increase in the number of bridges. Bridge maintenance and management are facing increasingly severe challenges.

[0003] Traditional bridge maintenance and management relies primarily on manual inspections and empirical judgment. This results in low efficiency, high costs, limited coverage, and is prone to major safety accidents such as falls, which impact the quality and durability of bridge projects. Intelligent maintenance technology, a new technology developed in recent years in the field of bridge maintenance, applies information technology, intelligentization, and automation to bridge maintenance and management. This technology can effectively improve bridge maintenance efficiency, reduce costs and the risk of bridge cracking, and improve bridge quality. Utility Model Content

DETAILED DESCRIPTION

[0027] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0028] refer to Figures 1 to 3 As shown, an intelligent maintenance system for bridge piers includes a pier body 1, a climbing formwork mechanism 2, an annular pipe 3, a sprinkler 4, a water supply pipe 5, a water supply pump 6, a water inlet pipe 7, a water reservoir 8, a pedestal 9, a diaphragm 10, an annular track 11, a traveling vehicle group 12, a hanging assembly 13, a maintenance film reel 14, a traveling motor 15, a traveling wheel 16, a vehicle body 17 and a time relay 18.

[0029] Pier 1 is a hollow, thin-walled reinforced concrete structure, but other structural forms are also possible. A reinforced concrete pedestal 9 is located beneath pier 1. This supports pier 1, ensuring stable and uniform downward pressure. A reinforced concrete diaphragm 10 is located within pier 1 to reinforce the internal structure.

[0030] The outer perimeter of the pier shaft 1 is equipped with a climbing formwork mechanism 2, an annular tube 3, and an annular track 11. The climbing formwork mechanism 2 is a conventional climbing formwork, serving as a construction platform and also possessing self-elevation capabilities. The climbing formwork mechanism 2, annular tube 3, and annular track 11 form a co-elevating unit. The climbing formwork mechanism 2 can simultaneously raise and lower the annular tube 3 and annular track 11. After a worker completes work on the climbing formwork mechanism 2, the annular tube 3 and annular track 11 can also rise and lower synchronously with the climbing formwork mechanism 2, completing their own functions.

[0031] A plurality of nozzles 4 are provided on the annular pipe 3, and the nozzles 4 are evenly distributed along the pipe body. The nozzles 4 face the pier body 1. The annular pipe 3 is connected to the water supply mechanism. The water provided by the water supply mechanism is sprayed at the nozzles 4 and then falls onto the pier body 1, thereby realizing water sprinkling maintenance of the concrete of the pier body 1.

[0032] A traveling vehicle 12 is mounted on the circular track 11 and connected to a hanging assembly 13. The hanging assembly 13 is equipped with a curing film reel 14 that rotates along a vertical axis. The traveling vehicle 12 moves in a circular motion on the circular track 11, carrying the hanging assembly 13 around the circumference of the pier 1. As the hanging assembly 13 moves, the curing film reel 14 is pulled and rotated, unwinding the film. This unwinding film wraps around the pier 1, improving the curing effect of the pier 1.

[0033] The climbing formwork mechanism 2 is positioned above the annular tube 3. After the personnel on the climbing formwork mechanism 2 complete their work on the pier body 1, the annular tube 3 rises to precisely spray water at that location for maintenance. The annular tube 3 is positioned above the curing film roll 14. After the annular tube 3 sprays water on the pier body 1, the curing film roll 14 rises to precisely cover that location. Alternatively, the pier body 1 can be covered first, and then water can be sprayed through the annular tube 3 to increase humidity.

[0034] The climbing formwork mechanism 2 is connected to the annular tube 3 by direct welding or screw fixation. The annular tube 3 is connected to the annular track 11 by slings, screws, or even by direct welding of a rectangular tube.

[0035] The water supply mechanism includes a water supply pipe 5, a water supply pump 6, a water inlet pipe 7, and a water reservoir 8. The water supply pipe 5 is connected to the annular pipe 3, which is in turn connected to the water supply pump 6, which is in turn connected to the water inlet pipe 7, which extends into the water reservoir 8. The water supply pump 6 pressurizes the fluid, pumps water from the water reservoir 8 through the water inlet pipe 7, and then delivers the water to the annular pipe 3 through the water supply pipe 5. The water is evenly sprayed through the nozzles 4 of the annular pipe 3.

[0036] The annular tube 3 is welded from several sections of bent steel pipe. The nozzle 4 is welded to the annular tube 3. Welding ensures the stability of the overall pipe structure and the sealing and waterproofing of the connection. After use, it is removed by cutting. Similarly, the annular tube 3 can also adopt other detachable connection methods, such as flange bolts or joint sleeves.

[0037] The water supply pipe 5 is a flexible pipe that can follow the rise and fall deformation transition of the annular pipe 3 to achieve water supply connectivity. The water supply pump 6 is equipped with a time relay 18, which controls the working cycle of the water supply pump 6 and the time and amount of water spraying during the watering maintenance.

[0038] The circular track 11 is welded from several sections of bent C-shaped steel. This welding ensures the stability of the overall track structure and provides good guidance and support for the traveling vehicle assembly 12. With the notch of the circular track 11 facing downward, the circular track 11 forms a barbed hook, confining the traveling vehicle assembly 12 within it and ensuring that the hanging assembly 13 passes through the notch.

[0039] The vehicle assembly 12 includes a travel motor 15, travel wheels 16, and a vehicle body 17. Rotating travel wheels 16 are mounted on either side of the vehicle body 17. These wheels 16 run along the edges of the circular track slots, allowing the vehicle to move freely along the track. The vehicle body 17 is equipped with a travel motor 15 that drives the travel wheels 16, providing power for their rotation.

[0040] The hanging assembly 13 is a T-shaped structural member, which includes a horizontal section and a vertical section. The curing film reel 14 is mounted on the vertical section, so that the curing film reel 14 can rotate freely along the vertical axis. A bearing can also be added between the reel and the vertical section to reduce the friction of rotation. The horizontal section clamps the lower end of the curing film reel 14 to prevent the reel from falling off, and the upper end of the vertical section is hung on the traveling vehicle group 12. The hanging assembly 13 realizes the placement of the curing film reel 14, moves the reel with it, and ensures the reel's self-rotation.

[0041] The workflow of this application:

[0042] 1. Based on the pier cap construction drawings and the construction plan layout, design and purchase high-lift water pumps, time relays, water sprinklers, DN30 steel pipes, 30mm water supply hoses, C-shaped steel, traveling trolleys, and maintenance film reels, and assemble one or more pier column intelligent maintenance systems on site.

[0043] 2. Use a pipe bender to bend the DN30 steel pipe into a ring on site, weld the ends together to form a passage, cut out the nozzle welding port and water supply inlet, and then weld the nozzle to form a ring water spray ring.

[0044] 3. The annular pipe is welded to the bottom of the climbing formwork construction platform, and the 30mm water supply hose is rigidly connected to the annular pipe. The length of the soft water pipe of the entire pier height is reserved, which can be lifted by climbing the climbing formwork, reducing excessive and complicated mechanical operations.

[0045] 4. Use C-shaped steel to make a circular track, which is connected to the circular pipe. The vehicle body is placed in the circular track. The vehicle body is equipped with running wheels, drive motor, hanging components and curing film. After the drive motor travels around the pier column for one circle to complete the film coating, water is sprayed inside to keep the concrete humidity of the pier column above 90%.

[0046] 5. Connect the water supply pipe to the high-lift water pump and place it in the water reservoir. Set the power-on time of the timer according to the size of the pier to meet the pier column curing time. The curing film is covered and wound from bottom to top. On the ground, the personnel cover the film on the pier. Then the walking group drives the reel to complete the film winding. Synchronously, the film is wound upwards as the climbing formwork is lifted. At the top, the film is cut at the cap beam platform.

[0047] 6. After the intelligent maintenance system is installed, it should be put into trial operation. If any water seepage or malfunction occurs during the trial operation, timely adjustments and repairs should be made nearby. After the pier column concrete is poured as a whole and reaches the maintenance-free condition, the intelligent maintenance system can be removed simultaneously with the removal of the climbing formwork.

[0048] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.

[0049] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
