Description

Technical Field

[0001] The invention relates to the technical field of bridge engineering construction, and in particular to a movable cantilever cast beam bridge inner box concrete curing device and method. Background Art

[0002] The current manual curing method for concrete mainly relies on artificial watering or artificially set wet cloth and other equipment. Although moist curing can be effectively achieved in simple environments, it is often difficult to achieve uniform and comprehensive curing effects in complex structures such as cantilever beam bridges. Especially in the corners and recessed parts of the box beam, moisture may accumulate or be unevenly distributed, resulting in local drying or excessive wetting of the concrete, which seriously affects the quality of the concrete.

[0003] The disadvantages of the existing technology are: the box girder of the cantilever bridge has a narrow internal space and a complex structure. The traditional maintenance equipment is large in size and poor in flexibility, making it difficult to enter the box girder for comprehensive maintenance operations. In particular, some fixed water spraying devices often cannot effectively cover all corners and hidden parts of the inner box, resulting in the appearance of maintenance blind spots and affecting the maintenance effect. Due to the irregular shape of the box girder, it is difficult for the existing maintenance methods to provide uniform maintenance conditions for different parts. For example, in some corners or protruding parts, moisture may accumulate or dry too quickly, thereby affecting the quality and strength development of concrete. The unevenness of maintenance may lead to insufficient strength or cracks in local areas, affecting the stability of the overall structure. Most of the existing concrete maintenance equipment relies on manual operation, which not only increases the labor intensity, but also makes it difficult to accurately control the maintenance parameters, such as water spraying time, interval, flow rate, etc. Manual operation often results in excessive or insufficient maintenance, resulting in unstable maintenance effects and failure to ensure that the humidity and temperature during the concrete hardening process are accurately controlled. Under different construction environments, such as high temperature, low temperature, high humidity, etc., the existing maintenance equipment is usually unable to automatically adjust the maintenance strategy according to environmental changes. For example, in hot weather, traditional manual watering methods may not be able to quickly and effectively maintain the required humidity of concrete, while in low temperature environments, temperature control may also have a lag, affecting the curing effect. Summary of the invention

[0004] The purpose of the present invention is to provide a movable cantilever cast beam bridge inner box concrete curing device and method to solve the problems of inconvenient curing operation, uneven curing effect, lack of automatic control and poor environmental adaptability in the process of curing concrete on the inner side of the cantilever beam bridge box girder in the prior art.

The water spray flow rate, water spray time and interval are adjusted according to the preset parameters of the control system to ensure uniform wetting of the concrete surface of the side wall and top of the inner box of the beam bridge;

[0017] S3. After the water spraying curing is completed, the concrete surface is covered and cured by a moisturizing covering system arranged on a mobile platform, wherein the moisturizing covering system includes an automatically retractable moisturizing covering layer, which is unfolded and covers the concrete surface by an electric reel device to prevent the water from evaporating too quickly;

[0018] S4, monitor the temperature and humidity inside the inner box of the beam bridge in real time through the temperature and humidity adjustment system installed on the mobile platform, and adjust the environment inside the inner box by using a heating or cooling device to keep the temperature and humidity within the optimal range for concrete curing;

[0019] S5. The maintenance process is automatically regulated by a control system. The control system is centered on a computer and collects data from temperature and humidity sensors and flow control valves in real time. The operation of the water spray system, the moisturizing covering system and the temperature and humidity adjustment system is controlled according to the collected data. The temperature and humidity conditions inside the inner box of the beam bridge, the water spray flow rate and the equipment operation status are displayed through a display instrument.

[0020] Preferably, the metal frame of the mobile platform is made of lightweight and high-strength aluminum alloy, and can be adjusted to a folded or unfolded state according to the actual shape and size of the inner box of the beam bridge.

[0021] Preferably, the nozzles of the water spray system are distributed in a ring shape, and the side walls, top and corners of the inner box of the beam bridge can be fully covered by adjusting the angles of the nozzles.

[0022] Preferably, the moisturizing cover layer is made of a moisturizing breathable material.

[0023] Preferably, the heating or cooling device of the temperature and humidity regulation system dynamically adjusts the temperature and humidity in the inner box of the beam bridge according to the real-time data of the temperature and humidity sensor.

[0024] It can be seen from the above technical solution that the present invention has the following beneficial effects:

[0025] The movable cantilever cast beam bridge inner box concrete curing device and method can flexibly adapt to the complex shape and size of the beam bridge inner box by setting a foldable metal frame of lightweight and high-strength aluminum alloy. At the same time, through the cooperation of the track and the walking wheel, the mobile platform can be smoothly moved to the curing area, avoiding the situation that traditional curing equipment is difficult to enter the inner box, greatly reducing the difficulty of operation, and using adjustable angle nozzles, which are distributed in a ring shape on the top of the platform, to achieve comprehensive coverage of complex parts such as the side walls, tops and corners of the beam bridge inner box, avoiding the maintenance blind spot problem caused by insufficient water spraying range in traditional curing methods. At the same time, the moisturizing covering system evenly covers the concrete surface with moisturizing breathable materials to avoid excessive evaporation of water, further ensure the uniformity of the curing effect, and improve the quality of concrete.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-Figure 3 As shown, a movable cantilever cast beam bridge inner box concrete curing device comprises a plurality of metal frames 1, wherein the plurality of metal frames 1 are connected by hinges, a running wheel 2, wherein the plurality of running wheels 2 are installed at the bottom of the metal frame 1, a track 3, wherein the running wheel 2 rolls on the track 3, and a water storage tank 4, wherein the water storage tank 4 is arranged inside the metal frame 1. The movable cantilever cast beam bridge inner box concrete curing device of the present invention utilizes a plurality of hinged metal frames to form a foldable or unfoldable frame structure, and the running wheel 2 installed at the bottom of the metal frame can roll on the track 3, thereby realizing the free movement of the device in the beam bridge inner box. A water storage tank 4 is arranged inside the device, and the water source in the water storage tank provides a water source or supply system for concrete curing. Its structural design enables the curing device to be efficiently moved to the target curing area, and has good stability and operability. The design of the metal frame 1 and the running wheel 2 connected by hinges enables the device to be flexibly moved in the beam bridge inner box to adapt to different spatial structures and curing requirements. A water storage tank 4 is provided to provide a continuous water source, and cooperate with the subsequent water spraying system to ensure sufficient water source during the concrete curing process. The hinge connection mode of the metal frame 1 enables the device to be adjusted to a folded or unfolded state according to the size of the beam bridge, thereby enhancing the adaptability and flexibility of the device.

[0033] In this embodiment, the structure using the metal frame 1 can adjust the shape and size according to actual needs. For example, the frame can be designed as a foldable structure to facilitate use and transportation in different environments. The water storage tank 4 can be configured at the top or bottom of the frame to ensure a stable water supply during the maintenance process. The water flow can be transported to the water spray system through a flexible water pipe to ensure the maintenance effect.

[0034] The metal frame 1 is made of a lightweight, high-strength aluminum alloy. The metal frame 1 is made of a lightweight, high-strength aluminum alloy, which not only ensures the strength and stability of the frame, but also makes the entire device light and easy to move and adjust. The use of aluminum alloy material improves the corrosion resistance and durability of the device, and is especially suitable for long-term use in humid environments. Aluminum alloy materials have high strength and low density, making the entire device lighter, easier to operate and move. Aluminum alloy has good corrosion resistance and can effectively prevent damage caused by long-term contact with water or moisture. Aluminum alloy has high mechanical strength and good load-bearing capacity, which can ensure that the frame is not easily deformed under high-intensity use environments.

[0035] The metal frame 1 can be connected by aluminum alloy welding technology, or can be spliced ​​with aluminum alloy profiles to further improve the overall structural stability of the device. Reinforcement measures can be added at the joints of the frame to ensure that the strength of the frame is not affected by the working environment.

[0036] The walking wheel 2 is made of rubber. The walking wheel 2 is made of rubber, which can effectively reduce the friction between the track and improve the stability and smoothness of the equipment. The flexibility of rubber also reduces the wear on the track, and at the same time can provide better grip to prevent the device from sliding or jamming on the track. The rubber material has a lower coefficient of friction, making the device roll more smoothly on the track. Rubber has good wear resistance and can meet long-term use requirements and avoid frequent replacement of parts. The elastic properties of rubber make it better to absorb vibration during walking, which can effectively reduce the impact on the structure and operation.

[0037] The rubber material of the running wheel 2 can be selected with different hardness according to the use environment to adapt to tracks of different hardness and working conditions. The design of the rubber running wheel can be customized according to the width and thickness of the track to ensure a good contact surface and avoid mismatching between the wheel and the track.

[0038] Track 3 is made of stainless steel. Track 3 is made of stainless steel, which has excellent corrosion resistance and high strength, and can maintain good stability and durability in long-term contact with water or humid environments. The sturdiness of the track ensures that the travel wheel can roll smoothly without deformation or damage. Stainless steel has strong corrosion resistance and can withstand humid or water vapor environments, and is not easy to rust or damage. Tracks made of stainless steel can withstand large loads and mechanical shocks, ensuring long-term stable operation of the equipment. The surface of stainless steel is smooth, easy to clean and maintain, and avoids maintenance problems caused by rust or wear of traditional material tracks. Track 3 can be made of stainless steel alloy to improve its durability and oxidation resistance, especially suitable for use in humid environments. The surface of the track can be treated with anti-slip treatment to increase the friction between the track and the travel wheel and improve the safety of the device.

[0039] The water storage tank 4 is equipped with a flow regulating valve and a switch. The water storage tank 4 is equipped with a flow regulating valve and a switch inside to control the size and flow state of the water flow. By adjusting the flow valve, the water volume of the water spraying system can be accurately controlled to ensure that the use of water sources during concrete curing is more efficient and economical. The flow regulating valve can adjust the size of the water flow to ensure that the flow of the water source is accurately controlled according to actual needs during the curing process. Through switch control, the water supply function of the water storage tank can be easily started or shut down, improving the convenience of operation. By accurately controlling the flow, water waste can be reduced and the purpose of water saving can be achieved.

[0040] The flow regulating valve can be designed as an automatic regulating type, and the water flow rate can be automatically adjusted according to the environmental humidity and temperature changes. The water storage tank 4 can be made of transparent materials, which is convenient for operators to check the water level and water flow state.

[0041] like Figure 4 As shown, a movable cantilever cast beam bridge inner box concrete curing method is also provided, using the movable cantilever cast beam bridge inner box concrete curing device, the method comprises:

[0042] S1. Lay tracks at the bottom of the inner box of the beam bridge, and place a movable platform on the tracks. The movable platform includes a plurality of metal frames connected by hinges, and running wheels are installed at the bottom of the frames. The running wheels roll on the tracks to the target maintenance area.

[0043] S2. Use a water spray system installed on a mobile platform to perform concrete curing. The water spray system includes a plurality of nozzles with adjustable angles. The nozzles are connected to a water storage tank through flexible water pipes. The water spray flow rate, water spray time and interval are adjusted according to the preset parameters of the control system to ensure uniform wetting of the concrete surface of the side wall and top of the inner box of the beam bridge;

[0044] S3. After the water spraying curing is completed, the concrete surface is covered and cured by a moisturizing covering system arranged on a mobile platform, wherein the moisturizing covering system includes an automatically retractable moisturizing covering layer, which is unfolded and covers the concrete surface by an electric reel device to prevent the water from evaporating too quickly;

[0045] S4, monitor the temperature and humidity inside the inner box of the beam bridge in real time through the temperature and humidity adjustment system installed on the mobile platform, and adjust the environment inside the inner box by using a heating or cooling device to keep the temperature and humidity within the optimal range for concrete curing;

[0046] S5. The maintenance process is automatically regulated by a control system. The control system is centered on a computer and collects data from temperature and humidity sensors and flow control valves in real time. The operation of the water spray system, the moisturizing covering system and the temperature and humidity adjustment system is controlled according to the collected data. The temperature and humidity conditions inside the inner box of the beam bridge, the water spray flow rate and the equipment operation status are displayed through a display instrument.

[0047] This maintenance method starts the water spraying system to moisten the concrete after the mobile platform rolls on the inner box of the beam bridge to the target maintenance area. At the same time, the temperature and humidity of the environment are kept within an appropriate range through the moisturizing covering system and the temperature and humidity adjustment system to ensure the effect and quality of concrete maintenance. The system automation control makes the entire maintenance process more accurate and efficient. Full-process automated monitoring and adjustment make the maintenance process more stable and efficient, avoiding errors caused by manual operation. The temperature and humidity control system can be adjusted according to actual needs to avoid excessive energy consumption and improve maintenance efficiency. The three measures of water spraying, moisturizing covering and temperature and humidity adjustment are used to comprehensively guarantee the maintenance quality of concrete. The temperature and humidity adjustment system can be integrated into the cloud platform for remote monitoring, and users can control and view data in real time through mobile devices. The water spraying system can be adjusted according to different types of concrete, using different types of nozzles or water spraying methods to meet different maintenance needs.

[0048] The metal frame of the mobile platform is made of lightweight and high-strength aluminum alloy, and can be adjusted to a folded or unfolded state according to the actual shape and size of the inner box of the beam bridge. The mobile platform of the present invention is made of lightweight and high-strength aluminum alloy, which ensures that the platform has sufficient strength and stability while being light. The metal frame is designed to be foldable or unfolded, so that the platform can be adjusted according to the actual size and shape of the inner box of the beam bridge, so as to better adapt to the inner boxes of beam bridges of different sizes and structures. The folding structure allows the device to take up less space during transportation and storage, and after unfolding, it can effectively cover the required area for maintenance work. The aluminum alloy material is not only lightweight, but also ensures the high strength of the platform, and can withstand the loads generated by the device itself and the maintenance process. The foldable or unfoldable design of the metal frame enables the mobile platform to adapt to the inner boxes of beam bridges of different shapes and sizes, enhancing adaptability and versatility. The folding structure can reduce the demand for transportation and storage space and improve work efficiency.

[0049] The sprinkler system has sprinkler heads arranged in a circular pattern. The sprinkler system has sprinkler heads arranged in a circular pattern to ensure uniform coverage and spraying of the concrete surface. The circular sprinkler head distribution can spray water mist evenly in all corners of the inner box of the beam bridge to avoid local insufficient or excessive wetting, thereby achieving uniform concrete curing. Each sprinkler head can adjust the spraying angle, flow rate and spraying time to meet the needs of different concrete surfaces. The sprinkler heads arranged in a circular pattern can ensure uniform water spraying in all areas of the concrete surface, effectively avoiding curing dead corners or overspraying. The adjustability of each sprinkler head angle and flow rate can be flexibly adjusted according to the conditions of the concrete surface to ensure the best curing effect. The circular sprinkler head distribution reduces the frequency of equipment position adjustment and improves work efficiency, especially when curing a large area.

[0050] The moisturizing covering system includes an automatically retractable moisturizing covering layer, which is unfolded and covers the concrete surface through an electric reel device to prevent the water from evaporating too quickly. The moisturizing covering system uses an automatically retractable moisturizing covering layer, which is unfolded and covers the concrete surface through an electric reel device to prevent the water on the concrete surface from evaporating too quickly during the curing process. The system adopts intelligent control. When the water spraying system completes the curing, the moisturizing covering layer will automatically unfold and cover the concrete surface to maintain the moist environment of the concrete. The electric reel device can ensure that the moisturizing covering layer is unfolded and retracted quickly and smoothly, providing a convenient operating experience. The moisturizing covering layer can effectively prevent the water from evaporating too quickly, maintain the appropriate humidity of the concrete during the curing period, and avoid cracks or substandard strength. Automatic unfolding and retraction are achieved through the electric reel device, reducing the need for manual operation and improving work efficiency. The moisturizing covering layer can be automatically unfolded when needed and can be fully retracted when not in use, saving space and facilitating the storage and transportation of the equipment.

[0051] The temperature and humidity control system includes a heating or cooling device that can adjust the temperature and humidity inside the inner box of the beam bridge according to the requirements of concrete curing. The temperature and humidity control system adjusts the ambient temperature and humidity inside the inner box of the beam bridge through an integrated heating or cooling device, thereby providing the most suitable environmental conditions for concrete curing. According to the requirements of concrete curing, the system can automatically identify changes in ambient temperature and humidity, and start the heating or cooling device for adjustment to ensure that the concrete is always under the best temperature and humidity conditions during the curing process, promote cement hydration reaction, and avoid cracks and strength reduction. The temperature and humidity control system can adjust the environment according to real-time data to ensure that the concrete is always hydrated under the best curing conditions. By automatically monitoring temperature and humidity, the system can automatically heat or cool according to changes, reduce manual intervention, and improve work efficiency. Adjusting temperature and humidity according to actual needs instead of continuously running heating or cooling equipment saves energy consumption.

[0052] Working process: First, a track 1 is laid at the bottom of the inner box of the beam bridge, and then a movable platform is placed on the track. The platform consists of a plurality of metal frames 2 connected by hinges, and a running wheel 3 is installed at the bottom of the frame. The running wheel rolls on the track to the target curing area 4. Then, a water spray system 5 arranged on the mobile platform is used to spray water mist on the concrete surface through a plurality of nozzles with adjustable angles to ensure that the concrete surface of the inner box of the beam bridge is evenly moistened 6. After the water spray curing is completed, the moisturizing covering system 7 on the platform is used to cover the concrete surface to prevent the water from evaporating too quickly 8. In addition, the platform is also equipped with a temperature and humidity adjustment system 9, which monitors the temperature and humidity in the inner box of the beam bridge in real time, and adjusts the ambient temperature and humidity through heating or cooling devices to keep it within the optimal range of concrete curing 10. The entire process is automatically adjusted by the control system 11 to ensure the stability and efficiency of the curing process.
