Description

Technical Field

[0001] This utility model relates to the field of bridge construction and maintenance technology, specifically a water spraying maintenance device for high bridge piers. Background Technology

[0002] In bridge construction, the quality of curing the concrete structure of bridge piers has a decisive impact on its durability and service life. Currently, common curing methods include traditional natural curing and curing agent curing. Traditional natural curing involves wrapping the pier body with geotextile and sprinkling it with water, then covering it with a plastic film to reduce surface moisture loss; while curing agent curing relies on spraying curing agents to inhibit the evaporation of moisture from the concrete surface. In recent years, some specialized curing equipment has also been applied in actual construction, such as sprinkler systems and mobile sprinkler systems. However, these existing technologies have revealed many problems in practical applications: traditional manual watering is difficult to cover the upper part of high piers, resulting in uneven curing and easy surface damage due to water flow impact; ordinary sprinkler systems have poor water retention, with water drying out quickly after application; automatic sprinkler systems are expensive and require complex pressurization equipment, and require customized designs for piers of different heights, resulting in poor applicability; film covering is only suitable for short-term curing, and long-term use will lead to condensation retention inside the film, affecting concrete strength and generating a large amount of waste, which does not meet the requirements of green construction.

[0003] To address the aforementioned issues, patent CN118727600A proposes a surround-type concrete spray curing device for bridge piers. This device achieves comprehensive and uniform water spray curing by installing a water storage tank at the top of the bridge pier and utilizing water supply pipes and spray heads extending downwards from the top. Simultaneously, a controlled actuator performs timed curing of the concrete. However, the fixed installation method of this device results in poor applicability, making it difficult to adapt to piers of different heights and shapes. It requires separate design and installation for each bridge pier, and the high cost and complex structure increase construction costs and maintenance difficulties, limiting its widespread application in practical engineering.

[0004] To address the issue of fixed installation, patent CN220224962U proposes a mobile curing agent spraying device for bridge pier maintenance. This device combines pump spraying with automatic lifting to achieve curing agent spraying, reducing labor costs and improving spraying efficiency and construction safety. However, the device still has some shortcomings: its complex electromechanical integrated system relies on a metal base, electric lifting, and annular spraying components, making the overall equipment relatively bulky and inconvenient for transportation and operation; the spraying components use atomizing nozzles, which, while achieving good atomization, also introduce the risk of nozzle clogging, affecting the continuity and stability of maintenance; furthermore, the annular spraying structure limits its applicability to piers of different diameters, making it difficult to meet diverse construction needs.

[0005] In summary, existing bridge pier maintenance technologies still have many shortcomings in terms of cost, operational flexibility, applicability, and environmental friendliness. Therefore, there is an urgent need for a portable, easy-to-assemble, and low-cost water spraying maintenance device for high bridge piers to overcome the deficiencies of existing technologies and meet the demands of modern bridge construction for efficient, economical, and environmentally friendly maintenance technologies. Utility Model Content

[0006] The purpose of this utility model is to provide a bridge high pier water spraying maintenance device to overcome the shortcomings of existing bridge high pier maintenance devices, such as complex structure, high cost, and poor adaptability.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A water spraying maintenance device for high bridge piers includes a horizontal pipe assembly and a vertical pipe assembly. One end of the horizontal pipe assembly and the vertical pipe assembly are connected and their interiors are interconnected. The other end of the vertical pipe assembly is provided with a flexible hose interface.

[0009] The vertical pipe assembly consists of multiple interconnected vertical pipe sections;

[0010] A mist spray area is arranged on the horizontal pipe assembly, and a sealing component is installed at the end of the horizontal pipe assembly.

[0011] The mist spray area consists of two rows of staggered water spray holes on the horizontal pipe assembly.

[0012] The water spray holes are opened along the axis of the horizontal pipe assembly, with a diameter of 2-4mm and a spacing of 20-40mm, and are staggered vertically.

[0013] The horizontal pipe assembly and the vertical pipe assembly are connected by a tee connector, which is a 90° right-angle connector. After connection, the axes of the horizontal pipe assembly and the vertical pipe assembly are perpendicular to each other.

[0014] Both the horizontal and vertical pipe assemblies are made of PVC pipes.

[0015] The end cap of the horizontal pipe assembly is a pipe cap.

[0016] The horizontal pipe assembly has an external thread structure at the port, and the pipe cap has an internal thread structure. The pipe cap is screwed tightly to the external thread at the end of the horizontal pipe to seal.

[0017] The horizontal pipe assembly has a "I" type structure.

[0019] The horizontal pipe assembly is formed by connecting multiple pipe sections to form an "I" shaped structure.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] This utility model provides a bridge pier water spraying maintenance device that effectively solves the problems of complex structure, high cost, and poor adaptability in existing technologies through the ingenious design of horizontal and vertical pipe assemblies.

This modular design allows the length of the vertical pipes to be freely adjusted according to the height of the piers, adapting to piers of different heights. Construction workers can flexibly adjust the height of the device simply by adding or removing vertical pipe sections as needed, eliminating the need for customized design and reducing construction costs.

[0023] The horizontal pipe assembly features mist spray zones, ensuring that water flows evenly across the pier surface in a misty manner, thus resolving the problem of uneven water distribution in existing technologies. Sealing elements installed at the ends of the horizontal pipe assembly prevent water leakage, further improving the device's sealing performance and spraying effectiveness.

[0024] In summary, the bridge pier water spraying maintenance device of this utility model effectively overcomes the shortcomings of the prior art through simplified structure, modular design and uniform spraying function, and provides a low-cost, easy-to-operate and highly adaptable maintenance solution.

[0030] In the field of bridge construction, the curing quality of bridge pier concrete structures directly affects their durability and service life. As the core load-bearing structure of bridge engineering, the curing method and quality of high bridge piers are important factors that restrict the improvement of concrete strength, hydration reaction, durability and appearance quality.

[0031] Currently, the main methods for curing concrete in tall structures such as bridge piers and abutments include manual watering, film covering, and spraying. These methods generally have the following problems: Traditional manual watering is difficult to cover the upper part of the pier or abutment, resulting in uneven curing. The strong impact of the water flow can easily cause surface damage, and it is difficult to control the amount of water sprayed, which can easily lead to local water accumulation or water shortage. Ordinary spraying devices have the problem that the water dries quickly after being poured, resulting in poor water retention. Automatic spraying systems are expensive and require complex pressurization equipment. They need to be customized for piers and abutments of different heights, resulting in poor applicability. Film covering is only suitable for short-term curing. Long-term covering can easily lead to condensation retention inside the film, affecting the concrete strength. It also cannot solve the problem of uniform water retention on the vertical structure facade, and at the same time, it generates a lot of waste, which does not meet the requirements of green construction.

[0032] Therefore, there is a need for a device that is low-cost, flexible in operation, water-saving, and can achieve uniform maintenance of the upper and lower parts of bridge piers. This utility model provides a height-adjustable water spraying nozzle based on PVC pipes, which can achieve uniform spraying of the bridge pier facade, and has the characteristics of low cost, easy disassembly and assembly, and water saving.

[0037] Reference Figures 1 to 4 The diagram illustrates a bridge pier water spraying maintenance device according to a specific embodiment of this utility model. It includes a horizontal pipe assembly 2 and a vertical pipe assembly 1, which are internally connected. One end of the vertical pipe assembly 1 is equipped with a flexible hose interface for easy connection to an external water source. The vertical pipe assembly 1 uses multiple interconnected vertical pipe sections 101, allowing for free adjustment according to the actual height of the bridge pier, ensuring the device's applicability. The horizontal pipe assembly 2 is equipped with a mist spraying area 201. A sealing element 202 installed at the end ensures that water is evenly sprayed through the spray holes 203 arranged on the mist spraying area 201, achieving comprehensive coverage of the bridge pier surface.

[0038] The mist spraying area 201 is formed by two rows of staggered spray holes 203 on the horizontal pipe assembly 2. The spray holes 203 are evenly spaced along the pipe axis, with a diameter of 2-4 mm and a spacing of 20-40 mm, and are staggered vertically. This design ensures that the water is sprayed evenly in a mist form, covering the pier surface, improving maintenance effectiveness, and reducing water waste.

[0039] The horizontal pipe assembly 2 and the vertical pipe assembly 1 are connected by a 90° right-angle tee connector 102, ensuring that their axes are perpendicular to each other. This connection method is simple in structure, easy to install, and ensures smooth water flow. Both the horizontal pipe assembly 2 and the vertical pipe assembly 1 are made of PVC pipe, which has the advantages of low cost, light weight, corrosion resistance, and long service life, and conforms to the concept of green construction.

[0040] The ends of the horizontal pipe assembly 2 are sealed by several sealing elements 202, specifically pipe caps. Each pipe cap is tightened with the external thread of each end of the horizontal pipe assembly 2 to seal, effectively preventing water leakage and ensuring stable system pressure. The horizontal pipe assembly 2 can be formed into an "I", "H" or "I" shape as needed to adapt to bridge piers with different cross-sectional dimensions, improving the applicability and flexibility of the device.

[0041] The bottom of the vertical pipe assembly 1 is equipped with a standard hose interface with an external thread design, which can be used with common water supply hoses on the market. Water source connection is achieved by tightening the thread, making the operation simple and quick. The vertical pipe assembly 1 is composed of multiple vertical pipe sections 101 connected end to end by a union. Adjacent pipe sections can be quickly disassembled and assembled by rotating the nut. A rubber sealing ring is provided at the connection to ensure sealing performance.

[0042] This utility model discloses a bridge pier water spraying maintenance device. Through a height-adjustable structural design and mist spraying technology, it achieves uniform spraying on the pier facade, while also being low-cost, easy to install and disassemble, and water-saving. The device is easy to operate, requiring only one person to complete installation and maintenance. It significantly improves the strength and durability of concrete, reduces manual climbing operations and investment in supporting equipment, and provides an efficient and economical maintenance solution for bridge pier construction.

[0043] To make the solution in this utility model easier to understand, the following is a specific implementation of the bridge high pier water spraying maintenance device in combination with actual use scenarios.

[0044] During bridge construction, workers needed to perform concrete curing on a 20-meter-high pier. First, based on the pier's height and cross-sectional dimensions, workers selected an appropriate number of vertical pipe sections 101 and horizontal pipe assemblies 2. The vertical pipe assembly 1 consisted of multiple vertical pipe sections 101 connected end-to-end by unions. Workers quickly disassembled and assembled adjacent pipe sections by rotating nuts, ensuring a good seal at the joints with the rubber sealing rings to prevent leakage.

[0045] The horizontal pipe assembly 2 is laterally extended into an "H" shape according to the cross-sectional shape of the pier through the tee joint 102 to adapt to the maintenance needs of the variable cross-section pier. The top surface of the horizontal pipe assembly 2 has two rows of staggered water spray holes 203 evenly distributed along the axial direction. The hole diameter is 3mm and the hole spacing is 30mm to ensure that the water is sprayed out evenly in the form of mist to cover the surface of the pier.

[0046] The standard flexible hose interface at the bottom of the vertical pipe assembly 1 is designed with external threads and is screwed tightly onto an external water supply hose to ensure a stable water supply. Construction workers install the device on top of the bridge pier and connect the water source to the interface at the bottom of the vertical pipe via the hose. Pressure water flow is generated inside the device, which is guided through the vertical pipe assembly 1 to the horizontal pipe assembly 2 and then sprayed out as mist-like water droplets through the spray nozzles 203, evenly covering the surface of the bridge pier and achieving full-height, no-dead-angle curing.

[0047] Throughout the maintenance process, construction workers can flexibly adjust the quantity and layout of horizontal pipe assembly 2 and vertical pipe assembly 1 according to the specific needs of the bridge piers. The portability and ease of assembly and disassembly of the device allow a single person to complete the installation and maintenance work, significantly reducing the risks of manual high-altitude operations and the investment in supporting equipment. The mist-like water flow has strong adhesion, greatly reducing water waste compared to traditional sprinkling methods and avoiding water erosion, thus meeting the requirements of green construction.

[0048] After maintenance, workers can quickly disassemble the device by rotating the nut and store it for future use. The entire process is simple, efficient, and water-saving, providing an economical and environmentally friendly maintenance solution for high bridge pier construction.

[0049] This utility model's bridge pier water spraying maintenance device, through optimized design, effectively solves the shortcomings of existing technologies and provides an efficient, economical, and environmentally friendly maintenance solution.

[0050] The device consists of a horizontal pipe assembly 2 and a vertical pipe assembly 1, which are internally connected. One end of the vertical pipe assembly 1 is equipped with a flexible hose interface for quick connection to an external water source. This simple structural design avoids the use of complex pumping systems or pressurization equipment, significantly reducing the complexity and cost of the device. The vertical pipe assembly 1 is composed of multiple interconnected vertical pipe sections 101, which can be freely adjusted according to the height of the bridge piers, adapting to piers of different heights and solving the problem of poor adaptability in existing technologies.

[0051] A mist spraying area 201 is arranged on the horizontal pipe assembly 2. Sealing elements 202 installed at each end of the horizontal pipe assembly 2 ensure that water is sprayed evenly, covering the surface of the bridge pier. The mist spraying area 201 is formed by two rows of staggered spray holes 203 opened on the pipe body of the horizontal pipe assembly 2. The hole diameter and spacing are precisely designed to ensure that the water is sprayed in a uniform mist form, improving the maintenance effect while reducing water waste.

[0052] The horizontal pipe assembly 2 and the vertical pipe assembly 1 are connected by a 90° right-angle tee connector 102, ensuring that their axes are perpendicular to each other, simplifying the installation process and enhancing overall stability. The horizontal pipe assembly 2 can be expanded into a "I", "H", or "I" type structure as needed to adapt to bridge piers with different cross-sectional dimensions, further improving the applicability of the device.

[0053] The bottom of the vertical pipe assembly 1 is equipped with a standard hose interface with an external thread design, which can be used with common water hoses on the market, making operation simple and quick. The vertical pipe assembly 1 consists of multiple vertical pipe sections 101 connected by unions. Quick assembly and disassembly can be achieved by rotating the nut. A rubber sealing ring is set at the connection to ensure sealing performance and prevent water leakage.

[0054] The end of the horizontal pipe assembly 2 is sealed with a pipe cap, which is tightened to the external thread of the horizontal pipe end to ensure stable system pressure and avoid water waste. The staggered distribution of the spray holes 203 further enhances the uniformity of spraying and avoids local water accumulation or water shortage.

[0055] In summary, this utility model's bridge pier water spraying curing device provides a low-cost, easy-to-operate, and highly adaptable curing solution through its simplified structure, modular design, and uniform spraying function. The device is convenient to operate; installation and curing can be completed by a single person. It significantly improves concrete strength and durability while reducing construction costs and the risks associated with manual work at heights.
