Description

Technical Field

[0001] This utility model relates to the field of municipal bridge engineering technology, specifically to a spray curing device for elevated bridge piers. Background Technology

[0002] As a vital component of modern urban transportation, elevated bridges rely heavily on their piers, which bear immense structural loads. After the concrete pouring of the piers is completed, effective curing is essential to ensure the quality, strength, and durability of the concrete. However, traditional methods for curing elevated bridge piers have several drawbacks: Many viaduct piers can reach heights of tens of meters or even higher. Manual curing typically requires the use of suspended platforms, aerial work platforms, and other high-altitude equipment, posing a significant risk of fall for workers. Manual curing is often intermittent, making it difficult to maintain a continuously moist concrete surface. This alternating wet and dry curing process can easily lead to micro-shrinkage cracks on the pier surface, affecting the concrete's density and impermeability, thus reducing its durability. High-altitude operations require substantial manpower and resources, and the curing process is limited by manual operation, resulting in low efficiency. Furthermore, curing work usually occupies some road space under or beside the bridge, setting up work areas that affect on-site traffic and production activities, increasing the difficulty and cost of construction management. Especially for piers with large or irregular cross-sections, manual spraying is difficult to achieve uniform coverage, leading to under- or over-curing in some areas, affecting the overall curing quality. Traditional curing methods are ill-suited to harsh weather conditions; for example, low temperatures may cause the concrete to freeze, while high temperatures and dryness accelerate moisture evaporation, affecting the curing effect.

[0003] Given the above background, developing a spray curing device for elevated bridge piers that can achieve automation, intelligence, high efficiency, safety, and excellent maintenance results has significant practical significance and application value. Utility Model Content

[0020] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a spray curing device for elevated bridge piers, which solves the technical problems of poor safety, poor effect, low efficiency, high cost and weak environmental adaptability in the prior art.

[0021] This embodiment introduces a spray curing device for the basic structure of elevated bridge piers, highlighting its core components and basic control functions.

[0022] Reference Figure 1 and Figure 2 As shown, the device in this embodiment includes a water storage system, a loop pipe system, a spray system, and a control system.

[0023] The water storage system mainly consists of a water tank 1 of suitable volume (e.g., a corrosion-resistant plastic bucket or metal tank) and a water pump 2 installed inside the water tank 1. The power of the water pump 2 should be selected according to the spraying requirements and lifting height. The water tank 1 is placed on the ground next to the pier for easy water filling and maintenance.

[0024] The ring system is installed on top of the pier. Its core structure is a square tube frame 5, which is made of multiple galvanized square steel bars with specifications of 40mm×40mm×2.5mm or customized according to the cross-sectional dimensions of the pier, connected end to end by welding to form a ring structure that matches the cross-sectional dimensions of the pier, and is firmly fixed to the top of the pier. The fixing method can be to temporarily weld the reserved installation holes on the square tube frame 5 to the reserved reinforcing bars 9 of the support pad stone at the top of the pier to ensure its stability. The spray ring pipe 6, such as a polyethylene (PE) pipe with a nominal diameter of 25mm (DN25), is arranged along the inner or outer side of the square tube frame 5 and fixed to the square tube frame 5 with cable ties or steel wire. The spray ring pipe 6 is provided with a main water inlet connected to the water pump 2, and multiple water outlets evenly distributed around the circumference. These water outlets can be connected by a tee connector 7 or a two-way connector to achieve flexible assembly of the spray ring pipe 6.

[0025] The sprinkler system consists of multiple adjustable shower heads. Each adjustable shower head 8 is connected to the outlet of the sprinkler ring pipe 6 via a tee connector 7. The arrangement density of the shower heads can be designed according to the perimeter of the pier and the desired maintenance effect, typically one every approximately 0.5 to 1.5 meters.

[0026] The control system includes a control box 4. The control box 4 integrates a timer switch and a level sensor. The water pump 2 is electrically connected to the power supply via the control box 4, and its start and stop are controlled by the timer switch within the control box 4. The timer switch can preset the duration and interval of the spraying maintenance. The level sensor is installed inside the water tank 1 to monitor the water level in real time. When the water level drops to a preset lower limit, the level sensor sends a signal to the control system, which then stops the power supply to the water pump 2 and may trigger an alarm, such as a buzzer or indicator light, installed on the control box 4, reminding management personnel to replenish water to the water tank 1 in a timely manner.

[0027] Workflow: Fill water tank 1 with water.

[0028] Start the control system and proceed with the preset maintenance duration and interval.

[0029] When the preset spraying time is reached, the control system starts water pump 2.

[0030] Water pump 2 lifts water from water tank 1 to the loop system via connecting hose 3.

[0031] Water is distributed to each outlet through the spray ring pipe 6.

[0032] The showerhead sprays water onto the surface of the pier for maintenance.

[0033] Once the preset spraying time is reached, the control system stops water pump 2.

[0034] During maintenance, the level sensor continuously monitors the water level. If the water level is too low, water pump 2 will be stopped in advance and an alarm will be triggered.

[0035] This embodiment, based on the aforementioned improvements, further refines the shower head structure and the intelligence level of the control system. Each adjustable shower head 8 is connected to a tee connector 7, which is connected to the spray ring pipe 6, via a ball joint structure. The ball joint structure allows the shower head to freely adjust the spray direction within a certain range to achieve effective coverage of various angles on the pier surface. Inside the shower head, a throttle valve is integrated, connected via an externally operable knob. The operator can adjust the opening of the throttle valve by rotating the knob, thereby precisely controlling the water output of the spray shower head to adapt to different concrete curing needs or environmental conditions.

[0036] The spray ring pipe 6 can be composed of multiple spray sections, and adjacent spray sections are connected by a three-way connector 7 or a two-way connector. This modular design facilitates flexible assembly according to the perimeter and shape of the pier column.

[0037] The adjustable shower head 8 can be connected to the spray ring pipe 6 via the T-connector 7. When the water outlet is located at the T-connector 7, connecting the shower head via the T-connector 7 allows for convenient adjustment of the spray direction and control of the water volume.

[0038] In the control box 4 described in the above embodiment, in addition to the timer switch and the liquid level sensor, environmental sensors can be further integrated. These environmental sensors may include temperature and humidity sensors to monitor the temperature and humidity of the environment surrounding the pier; an anemometer to measure wind speed; and a light sensor to measure light intensity. These environmental sensors are electrically connected to the control box 4 and transmit the collected environmental data to the control system. The control system can further optimize the spraying strategy based on this environmental data. For example, in high-temperature, dry environments with high wind speeds, the spraying frequency and water volume can be appropriately increased to reduce water evaporation; in low-temperature environments, spraying can be reduced to prevent the concrete from freezing.

[0039] In addition, a flow sensor can be installed on the connecting hose 3 or the spray ring pipe 6, and electrically connected to the control box 4. The flow sensor can monitor the water flow through the system in real time, ensuring that the spray volume reaches the preset standard, and can also be used to calculate the total water consumption, thus achieving water-saving management. The control box 4 is configured to preset the spray duration and interval via a timer switch, monitor the water level in the water tank 1 via a level sensor, and stop the power supply to the water pump 2 and trigger the alarm when the water level is lower than the preset lower limit.

[0040] Now, with the introduction of environmental and flow sensors, the control system can achieve more intelligent sprinkler maintenance. For example, it can automatically adjust the spraying duration and interval based on data such as temperature, humidity, and wind speed. Feedback from the flow sensor ensures that the water volume for each spray meets requirements. In addition to low water level alarms, it can also provide early warnings of extreme weather conditions that may affect maintenance, based on data from environmental sensors.

[0041] The focus of this embodiment is to optimize the design of the square tube frame 5 so that it can better adapt to piers of different shapes and sizes and provide a simpler fixing method.

[0042] An optional design for the square tube frame 5 includes multiple straight square steel bars. The straight square steel bars have grooves, allowing adjacent bars to slide through these grooves and be fixed by welding. This design allows the square tube frame 5 to adjust its perimeter or side length within a certain range to accommodate square piers of different sizes. After multiple sets of parallel square steel bars form a ring structure, reinforcing square steel bars are then added, with each end of these reinforcing square steel bars perpendicularly welded to two parallel square steel bars from the same set.

[0043] Another alternative is that the square tube frame 5 is composed directly of multiple curved square steel bars, which are spliced ​​together circumferentially and fixed by welding. This design is particularly suitable for circular or near-circular piers.

[0044] Another option is that the square tube frame 5 has multiple straight square steel bars and multiple curved square steel bars, with the curved square steel bars set at the corners of the straight square steel bars, which is suitable for rounded rectangular pier columns.

[0045] One method of fixing is to temporarily weld the square tube frame 5 to the pre-reserved steel bars 9 of the pier top support pad stone.

[0046] To improve the disassembly and reusability of the device, and to avoid the minor impact that welding might have on the existing structure, the following non-welding fixing method can also be adopted: The ring pipe system can be temporarily fixed to the reserved reinforcing steel 9 by setting fasteners that match the reserved reinforcing steel 9 of the support pad stone at the top of the pier, such as U-shaped clips, clamps, or prefabricated connecting blocks. These fasteners can be adjusted and locked by bolts or other fastening mechanisms to ensure the stable installation of the ring pipe system, while facilitating quick disassembly after maintenance.

[0047] This embodiment introduces a water collection and circulation system to achieve water recycling, reduce water consumption, and minimize environmental pollution. The water collection and circulation system includes a water collection tank and a sedimentation and filtration device located below the adjustable shower head 8.

[0048] The water collection trough is designed to surround the pier, its shape matching the pier's cross-section, effectively collecting wastewater sprayed from the sprinkler that has not been absorbed by the concrete. The inner wall of the trough should be smooth and have a suitable slope to guide the collected wastewater to an outlet. The trough is connected to a sedimentation and filtration device via a drainage pipe. The sedimentation and filtration device can be a multi-layered box containing a coarse filter, a fine filter, a sedimentation tank, and adsorption materials (such as activated carbon). The wastewater first undergoes sedimentation, with larger particles settling to the bottom; then it is filtered through the filter to remove suspended solids; finally, it is further purified by the adsorption materials. The sedimentation and filtration device is connected to a water storage tank 1 via a return water pipe. The treated purified water is returned to water storage tank 1 for the next round of spray curing.

[0049] Wastewater generated during the spraying process is collected in a collection tank, treated by a sedimentation and filtration device, and then reinjected into water tank 1, achieving a closed-loop water circulation. This significantly reduces dependence on external water sources, offering a substantial advantage, especially in water-scarce areas. It also prevents the direct discharge of untreated maintenance wastewater, meeting environmental protection requirements. Furthermore, it reduces water costs.

[0050] This embodiment focuses on solving the problem of icing and cracking that may occur in the device during cold winters or low-temperature environments, ensuring the normal operation of the device under low-temperature conditions.

[0051] Antifreeze systems can be implemented in one or more of the following ways: A layer of thermal insulation material, such as foam plastic, rock wool, or aerogel, is wrapped around the outside of the water pump 2 and the loop system (including the spray loop 6, connecting hose 3, and tee connector 7, etc.). This material can effectively prevent external cold air from directly contacting the pipes and water pump 2, slowing down their temperature drop and preventing the internal water from freezing.

[0052] Electric heating tape is wrapped around the outside of water pump 2 and the loop system. When energized, the heating tape generates heat, continuously heating the pipes and water pump 2, maintaining the flow of water even at extremely low temperatures and preventing freezing. The power and length of the heating tape should be selected based on the ambient temperature and pipe size, and managed centrally by the control system. It intelligently starts and stops based on temperature sensor data, achieving energy savings. This ensures reliable operation of the device in winter or low-temperature regions, preventing damage from freezing and cracking. It avoids equipment damage caused by icing.

[0053] For ultra-high piers or scenarios requiring maintenance in different areas and time periods, this embodiment proposes a segmented maintenance and zoned control scheme.

[0054] At least two sets of ring pipe systems and sprinkler systems are installed at intervals along the height to achieve segmented maintenance of ultra-high piers. For example, for a 100-meter-high pier, two or three independent sprinkler maintenance systems can be installed, with each layer responsible for maintaining a portion of the pier's height. This allows for more concentrated maintenance of specific areas and also allows for adjustments to the maintenance strategy for each segment as needed.

[0055] Each loop system and sprinkler system is further divided into at least two independently controllable sprinkler zones. For example, a loop can be designed with two sections, front and back, or left and right.

[0056] Multiple adjustable shower heads 8 within each spray zone are connected to the main water supply line via an independent solenoid valve. The control system can independently control the opening and closing of each solenoid valve, thereby enabling independent start-up, shutdown, and maintenance of different spray zones.

[0057] It can develop differentiated maintenance plans based on the stress and heat dissipation conditions of different parts of the pier. Segmented and zoned control allows for more precise maintenance management; for example, more frequent spraying can be applied to areas at the top that are more affected by wind and rain. Depending on actual needs, only certain spraying areas can be activated, saving energy and water resources.

[0058] This embodiment integrates and modularizes the overall design of the device, and enhances its communication and data management capabilities.

[0059] The water tank 1 can be designed to be mobile, for example, designed as a container structure with wheels, so that it can be easily towed by engineering vehicles to different piers and can be easily installed and disassembled.

[0060] To improve water quality and simplify maintenance, water tank 1 can integrate a multi-stage filtration system to remove impurities from the water; it can also integrate an ultraviolet sterilization device to prevent algae growth and maintain water cleanliness. Water tank 1 can also integrate an integrated water pump 2 and control panel to form a standalone, quickly deployable maintenance unit.

[0061] The square tube frame 5 adopts a detachable design, for example, it is made up of multiple adjustable-length square tubes connected by bolts instead of welding. This modular design allows the frame to be precisely adjusted according to the diameter or side length of the pier, and it is easy to assemble, disassemble, transport and store, improving the versatility and economy of the device.

[0062] The spray ring pipe 6 can be a specially designed PE pipe with integrated nozzles. This type of pipe has uniformly distributed nozzles pre-installed during manufacturing. The nozzles can be designed to produce fan-shaped or mist-like water flow, and their angle and flow rate are adjustable. Using this type of pipe greatly simplifies on-site installation, reduces the use of tee joints 7 and shower heads, lowers the risk of leakage, and improves installation efficiency.

[0063] The control system may further be integrated with a wireless communication module, such as a GPRS, NB-IoT or Wi-Fi module. Through these modules, the device can implement data interaction with a management backend.

[0064] The device can periodically upload data such as maintenance status (e.g., spraying in progress, completed, fault), spraying duration, water consumption, environmental sensor data (temperature, humidity, wind speed, light intensity), water level of the water tank 1, and equipment fault information to a cloud server or the mobile APP / computer terminal of management personnel through a wireless network.

[0065] Management personnel can remotely view the working status of each pier column maintenance device in real time, perform remote parameter setting (e.g., adjusting spraying duration, intervals, and water volume), and receive alarm information such as low water level and equipment fault in time, so as to realize centralized and intelligent management of the entire project.

[0066] A temperature and humidity sensor, an anemometer and a light sensor are configured. The control system can not only simply adjust the spraying intensity based on these data, but also implement more complex linkage strategies: When the wind speed is excessively high, the spraying angle of the shower nozzles can be adjusted to make them closer to the surface of the pier column, or spraying can be suspended, so as to prevent water mist from being blown away, which causes ineffective spraying and waste.

[0067] Under strong light, the spraying density can be increased to counteract the increase in surface temperature and water evaporation caused by light.

[0068] All environmental sensor data are comprehensively used to establish a comprehensive environment adaptation model, so as to realize optimized maintenance.

[0069] In this embodiment, the high-pressure atomization spraying technology is introduced to further improve the spraying fineness and maintenance effect.

[0070] The spraying system may be integrated with the high-pressure water pump 2 and micro-atomization nozzles. The high-pressure water pump 2 can pressurize water to a pressure much higher than that of an ordinary water pump 2 (for example, above 3MPa), and atomize water into ultra-fine water mist particles with a diameter of less than 50 microns through the specially-made micro-atomization nozzles. These ultra-fine water mists have stronger suspension capacity in air, form a uniform and fine moist film, and can cover the surface of the pier column slowly and uniformly.

[0071] In the water storage system, a solar panel can be arranged beside the water tank 1, and an energy storage battery pack is equipped. The solar panel converts solar energy into electric energy to supply power for the water pump 2, the control system and the sensors. The energy storage battery pack can store surplus electric energy and supply power at night or on cloudy days.

[0072] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include: High safety: The device operates automatically on top of the pier, eliminating the need for personnel to work at heights and greatly reducing operational risks.

[0073] Significant curing effect: Through intelligent control, the spraying time, interval, water volume and direction can be precisely adjusted to ensure that the concrete surface is continuously moist, effectively avoid shrinkage cracks, and improve the density and durability of concrete.

[0074] High efficiency and low cost: Automated operation reduces reliance on manual labor, improves maintenance efficiency, and reduces labor and material costs.

[0075] Highly adaptable: The device can be customized according to the shape and size of the pier to achieve uniform coverage. Furthermore, maintenance strategies can be adjusted based on environmental factors (such as temperature, humidity, and wind speed), making it even more adaptable.

[0076] Intelligent management: The control system integrates multiple sensors and control functions, enabling remote monitoring and early warning, and facilitating management and maintenance.

[0077] Water conservation and environmental protection: The application of the water collection and recycling system can recover part of the spray wastewater, which can be recycled after sedimentation and filtration, thus saving water resources.

[0078] Those skilled in the art will understand that the steps, measures, and schemes in the various operations, methods, processes, and procedures discussed in this application can be alternated, modified, rearranged, decomposed, combined, or deleted.

[0079] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
