Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to an air curtain type cantilever cast beam bridge outer box concrete curing device and method. Background Art

[0002] In bridge construction, the outer box of the bridge is usually cast with concrete. Concrete maintenance is crucial to ensure the quality of the outer box of the bridge. Good maintenance can enable the concrete to meet the expected strength and durability requirements. In traditional construction methods, the maintenance of concrete mainly relies on workers to pull hoses for maintenance. The water inlet is limited, the hose distance is long and the operation is unchanged, and manual maintenance generally has problems such as incomplete and uneven maintenance. Especially when the formwork is just removed, the concrete hydration heat is serious and the temperature is high. If the weather is hot and the air is dry, if the maintenance is not carried out in time, the water in the concrete will evaporate too quickly, forming a dehydration phenomenon, which will make the cement particles that have formed a gel body unable to fully hydrate and cannot be converted into stable crystals. There is a lack of sufficient bonding force, which will cause flaking or powdery shedding on the concrete surface.

[0003] The main shortcomings of the existing technology are uneven maintenance: traditional manual water spraying maintenance or simple covering maintenance methods often cannot ensure that all parts of the bridge outer box can get uniform water supply and suitable maintenance environment. For example, for some bridge outer boxes with complex shapes, many protruding structures or corners, manual water spraying may not be sprayed in place, causing part of the concrete surface to dry too quickly, affecting its strength development; low maintenance efficiency: manual maintenance methods require a lot of manpower and time, and it is difficult to achieve continuous and uninterrupted maintenance. Especially for large-scale bridge projects with large outer box areas, manual maintenance is not only labor-intensive, but also prone to untimely maintenance, thus affecting the quality of concrete; poor environmental adaptability: some existing maintenance devices cannot adjust the maintenance strategy well to meet the requirements of concrete maintenance under different climatic conditions, such as high temperature, low temperature, strong wind, etc. For example, in hot and dry weather, ordinary covering maintenance may not be able to effectively prevent the moisture in concrete from evaporating too quickly; in windy weather, simple water spraying maintenance may cause the moisture to be blown away and fail to form an effective maintenance layer on the concrete surface; lack of intelligent monitoring and control: most traditional maintenance methods cannot monitor key parameters such as humidity and temperature of concrete in real time, and cannot adjust maintenance measures in time according to actual conditions. This may lead to over-maintenance or under-maintenance during the maintenance process, making it difficult to accurately control the maintenance quality of concrete. Summary of the invention

[0004] The purpose of the present invention is to provide an air curtain type cantilever cast beam bridge outer box concrete curing device and method to solve the problems existing in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solution: an air curtain type cantilever cast beam bridge outer box concrete curing device, comprising:

[0006] A maintenance frame, the maintenance frame comprising a plurality of rods;

[0007] A nozzle, wherein a plurality of nozzles are evenly arranged on the top of the curing frame, and the nozzles are connected by rubber hoses;

[0008] A temperature and humidity sensor is connected to the maintenance frame and is used to monitor the temperature and humidity of the concrete surface of the bridge outer box and its surrounding environment in real time.

[0009] Preferably, the curing frame is an adjustable structure, and its height and width can be adjusted according to the size of the concrete surface.

[0010] Preferably, the nozzle is an angle-adjustable nozzle, and the spraying angle can be adjusted according to actual needs to ensure that the airflow evenly covers the concrete surface.

[0014] S1. Setting a maintenance frame, which includes a plurality of rods and can be adjusted according to the size of the bridge outer box concrete;

[0015] S2. Multiple nozzles are evenly arranged on the top of the curing frame, and the nozzles are connected by rubber hoses, and the nozzles are used to spray airflow to cover the concrete surface and its surrounding environment;

[0016] S3, real-time monitoring of the temperature and humidity of the concrete surface of the bridge outer box and its surrounding environment, wherein the humidity sensor is connected to the maintenance frame, and the temperature and humidity sensor is used to collect data and transmit the data to the control module;

[0017] S4. According to the temperature and humidity data monitored by the temperature and humidity sensor, adjust the air flow rate and spray angle of the nozzle to ensure that the concrete surface is moist and meets the maintenance requirements.

[0018] Preferably, in S4, when adjusting the air flow rate and the spraying angle, the air flow rate and the spraying angle are automatically adjusted according to the monitoring data fed back in real time by the temperature and humidity sensor to maintain the wet state of the concrete surface and avoid excessive evaporation.

[0019] Preferably, in S1, the curing frame is a telescopic structure, which can be automatically adjusted according to the size of the outer box of the beam bridge, so as to adapt to the curing requirements of concrete of different sizes.

[0020] Preferably, the nozzle is an adjustable angle nozzle, which can adjust the spraying angle according to actual needs, so that the airflow evenly covers the concrete surface and improves the curing effect.

[0021] Preferably, the temperature and humidity sensor is of a wireless transmission type, and can transmit monitoring data to the control module in real time to achieve remote monitoring and adjustment.

[0022] It can be seen from the above technical solution that the present invention has the following beneficial effects:

[0023] The air curtain type cantilever cast beam bridge outer box concrete curing device and method can ensure the uniform distribution of humidity on the concrete surface and its surrounding environment by setting a plurality of evenly distributed nozzles and using the airflow generated by the air curtain device to cover the concrete surface, thereby avoiding the phenomenon of excessive local drying that may occur in the traditional manual water spray curing method. Especially for the bridge outer box with complex shape or protruding structure, the airflow spraying can effectively cover all parts to ensure the comprehensiveness and uniformity of the curing. Continuous and uniform curing is achieved through the automatic control system without manual intervention, which greatly reduces the time and labor intensity of manual operation, and also avoids the problem of untimely or uneven curing caused by improper operation in manual curing. Especially for large-scale bridge projects, the curing efficiency is greatly improved, ensuring the continuous wetting and temperature control of large-area concrete surfaces. The spray angle and flow rate of the airflow can be flexibly adjusted under different environmental conditions to adapt to various weather conditions such as high temperature, dryness, and strong winds. Compared with traditional covering maintenance and artificial water spraying maintenance methods, the air curtain device can more effectively prevent the water in the concrete from evaporating too quickly, especially in hot weather, and can avoid dehydration caused by excessive water loss, thereby improving the strength and durability of the concrete. Through real-time monitoring and feedback of the humidity sensor, combined with the automatic adjustment of the control module, the present invention can detect the humidity and temperature data of the concrete surface in real time, and automatically adjust the air flow and injection angle according to the data to ensure that the maintenance environment is always in the best state. This intelligent function effectively solves the problem that the traditional maintenance method cannot accurately monitor the state of concrete and adjust the maintenance strategy, avoids over-maintenance or insufficient maintenance, and improves the maintenance quality of concrete. Through the maintenance method and device of the present invention, the concrete surface can be kept moist and the cement particles can be ensured to be fully hydrated, thereby improving the strength, durability and surface quality of the concrete, avoiding the problem of concrete surface shedding caused by dehydration and insufficient hydration of the gel, and ultimately improving the overall quality of the bridge outer box concrete.

[0029] 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.

[0030] like Figure 1-Figure 3 As shown, an air curtain type cantilever cast beam bridge outer box concrete curing device is characterized in that it includes: a curing frame 1, which includes a plurality of rods; a nozzle 2, wherein a plurality of nozzles 2 are evenly arranged on the top of the curing frame 1, and the nozzles 2 are connected by a rubber hose; a temperature and humidity sensor 3, which is connected to the curing frame 1, and monitors the temperature and humidity of the bridge outer box concrete surface and its surrounding environment in real time. The device supports the entire system through the curing frame 1, and the frame can adjust its height and width to adapt to concrete surfaces of different sizes. A plurality of nozzles 2 are evenly distributed on the top of the curing frame, and are connected to the air source through a rubber hose, and are used to spray air to cover the concrete surface and maintain appropriate humidity. The temperature and humidity sensor 3 monitors the environmental conditions in real time and transmits the data to the control module, and the control module automatically adjusts the air flow and angle of the nozzle according to the sensor data, so as to ensure that the concrete surface is moist and the curing environment is stable. By adopting the device of the present invention, the temperature and humidity can be accurately controlled during the concrete curing process, and concrete cracks or uneven hardening caused by environmental changes can be effectively avoided. At the same time, the maintenance frame 1 is designed as an adjustable structure that can adapt to different sizes of bridge outer box concrete. The uniform arrangement of the nozzles 2 ensures comprehensive airflow coverage. The real-time feedback of the temperature and humidity sensor 3 improves the intelligence level of the maintenance process, saves manpower and resources, and improves the maintenance effect. In addition to the above-mentioned embodiments, the device of the present invention can use different materials to manufacture the frame such as aluminum alloy, steel, etc. to improve durability and strength. The nozzle 2 can adopt different types of spray designs, such as micro-spray nozzles or atomizing nozzles, to adapt to different environmental conditions. The temperature and humidity sensor 3 can also realize remote wireless data transmission and intelligent control through improved design, thereby enhancing the flexibility and adaptability of the equipment.

[0031] The curing frame 1 is an adjustable structure, which can adjust its height and width according to the size of the concrete surface. The curing frame 1 can automatically adjust the height and width through an adjusting device such as an electric or hydraulic device to ensure that the frame can adapt to concrete surfaces of different sizes. The adjusted frame can stably support the nozzle 2 to ensure that the airflow evenly covers the concrete surface. During the curing process, the frame can be adjusted according to the actual size to ensure that the device can adapt to the curing needs under different working conditions. Through the adjustable structure of the frame, the device can flexibly adapt to the concrete curing needs of bridges of different sizes without replacing the equipment or manually adjusting the frame, which greatly improves the versatility and adaptability of the device. In addition, the frame has high adjustment accuracy and can accurately adapt to the actual size of the concrete outer box, thereby ensuring the uniformity and stability of the curing airflow and improving the curing effect. The adjustable frame 1 of this embodiment can adopt a hydraulic telescopic structure or a mechanical sliding device to adapt to more complex operating requirements. The adjustment mechanism of the frame can also be combined with an intelligent control system to automatically adjust according to the size of the concrete and environmental conditions, further improving the automation and intelligence level of the device.

[0032] Nozzle 2 is an adjustable angle nozzle, which can adjust the spray angle according to actual needs to ensure that the airflow evenly covers the concrete surface. Nozzle 2 is designed as an adjustable angle structure, which can adjust the spray angle by mechanical or electric devices. The airflow is evenly distributed through the nozzle, and the angle is adjusted according to the shape of the concrete surface and the maintenance requirements to ensure the uniformity and coverage of the airflow. This structure can effectively avoid the difference in maintenance effect caused by uneven airflow and ensure that the wet state of each part is consistent. Through the design of the adjustable angle nozzle 2, the airflow can be optimized and adjusted according to actual needs to ensure that the concrete surface is evenly moistened and avoid local overdrying or overwetting. This design not only improves the uniformity of the maintenance effect, but also can adapt to concrete outer boxes of different shapes and sizes, further improving the applicability and flexibility of the device. Nozzle 2 can be designed into various types according to specific needs, such as rotary nozzles, adjustable jet nozzles, etc., to adapt to the shapes and structures of different bridge outer boxes. The adjustment angle of the nozzle can be achieved by manual, mechanical or electric devices, and can be remotely adjusted through an intelligent control system to automatically optimize the airflow distribution under different environments.

[0033] The humidity sensor 3 is a digital humidity sensor, and the humidity sensor 3 transmits the real-time monitoring data to the control module wirelessly, which is convenient for remote monitoring and adjusting the curing environment. The humidity sensor 3 adopts a digital design and has higher accuracy and reliability. The sensor transmits the monitored temperature and humidity data to the control module in real time by wireless means, and the control module adjusts the air flow and angle of the nozzle 2 according to the data fed back by the sensor, so as to ensure that the concrete surface is in a suitable humidity condition. Through wireless transmission, the operator can remotely monitor the curing environment without directly operating on site. The digital humidity sensor 3 can provide higher accuracy and faster response speed, and monitor the temperature and humidity changes of the curing environment in real time. Wireless data transmission makes the curing process more intelligent, and the operator can remotely control the curing process in real time, thereby greatly improving the automation and convenience of the curing process. In addition, the system can also reduce manual intervention and improve the efficiency and accuracy of curing. The humidity sensor 3 can use other types of sensors, such as temperature and humidity integrated sensors or split sensors, and can even realize the automatic upload of sensor data to the cloud platform by combining the Internet of Things technology, which is convenient for centralized management and analysis of multiple sites. The sensor's wireless module can also be designed to be networked with other devices to form a more comprehensive intelligent monitoring system.

[0034] The maintenance frame 1 is a telescopic structure that can be automatically adjusted according to the size of the bridge outer box. The maintenance frame 1 in the present device adopts a telescopic structure, and through a hydraulic or electric adjustment device, the frame can be automatically adjusted according to the size of the bridge outer box concrete. The telescopic function of the frame enables the device to adapt to bridge outer boxes of different sizes. During the adjustment process, the frame will detect the actual size of the concrete surface through a sensor and automatically adjust it so as to accurately align the concrete surface and ensure that the nozzle 2 sprays the airflow to cover the entire surface. By using a telescopic structure, the maintenance device has higher adaptability and flexibility, and can meet the concrete maintenance needs of different bridge outer box sizes without manual intervention or replacement of equipment. The automatic adjustment function of the telescopic structure can effectively improve work efficiency and reduce errors caused by human operation. The overall design ensures that the airflow can evenly cover the concrete surface of the bridge outer box, thereby improving the maintenance quality. In addition to the hydraulic or electric telescopic structure, the present embodiment can also use springs or pneumatic methods to achieve automatic adjustment of the frame. According to the needs of different working environments, the telescopic device of the frame can adopt an intelligent control system, which can automatically adjust the size data fed back by the sensor to further improve the degree of automation and adjustment accuracy.

[0035] like Figure 4 As shown, a method for curing concrete of an outer box of a cantilever cast beam bridge with an air curtain is also provided. The method adopts the device for curing concrete of an outer box of a cantilever cast beam bridge with an air curtain. The method comprises:

[0036] S1, setting a maintenance frame 1, which includes a plurality of rods and can be adjusted according to the size of the bridge outer box concrete;

[0037] S2, a plurality of nozzles 2 are evenly arranged on the top of the curing frame 1, and the nozzles 2 are connected by rubber hoses, and the nozzles 2 are used to spray airflow to cover the concrete surface and its surrounding environment;

[0038] S3, real-time monitoring of the temperature and humidity of the concrete surface of the bridge outer box and its surrounding environment, the humidity sensor 3 is connected to the maintenance frame 1, and the temperature and humidity sensor 3 is used to collect data and transmit the data to the control module;

[0039] S4. According to the temperature and humidity data monitored by the temperature and humidity sensor 3, the air flow rate and the spraying angle of the nozzle 2 are adjusted to ensure that the concrete surface is moistened and meets the maintenance requirements.

[0040] This method is to install the curing frame 1 on the concrete surface of the outer box of the bridge, and automatically adjust the size of the frame according to actual needs to adapt to different concrete surfaces. The nozzle 2 is connected to the air source through a rubber hose and is evenly distributed on the top of the frame to spray air to cover the concrete surface. During the curing process, the temperature and humidity sensor 3 monitors the temperature and humidity of the surrounding environment in real time and transmits the data to the control module. The control module adjusts the air flow and injection angle of the nozzle according to the temperature and humidity feedback to ensure that the concrete surface maintains a suitable wet state. This method can accurately control the wet state of the concrete surface by automatically adjusting the size of the curing frame, the angle of the nozzle and the air flow. The real-time monitoring and data feedback mechanism effectively avoids the influence of environmental changes on the curing effect of concrete, ensuring that the curing process is stable and efficient. By accurately controlling humidity and airflow, this method can not only improve the hardening quality of concrete, but also improve construction efficiency and reduce unnecessary energy consumption and waste of resources.

[0041] Under different environmental conditions, different types of designs can be made for the nozzle 2, such as using a nozzle with adjustable flow rate or a nozzle with self-cleaning function. The control module can also be set as a remote control system according to different needs to achieve centralized management of bridge maintenance in multiple locations. At the same time, the temperature and humidity sensor 3 can also be replaced with a sensor with higher accuracy or longer monitoring distance to adapt to more complex construction conditions.

[0042] In S4, when adjusting the airflow and the spray angle, the airflow and the spray angle are automatically adjusted according to the monitoring data fed back in real time by the temperature and humidity sensor 3 to keep the concrete surface moist and avoid excessive evaporation. During the curing process, the method monitors the humidity and temperature data of the environment in real time through the temperature and humidity sensor 3, and transmits the data to the control module. The control module automatically adjusts the spray angle and the airflow of the nozzle 2 according to these data. When the temperature is too high or the humidity is too low, the system will automatically increase the airflow and adjust the spray angle to keep the concrete surface in a suitable moist state, avoid excessive evaporation of water, and ensure that the concrete is cured in a suitable humidity environment. Through the automated airflow adjustment system, the method can accurately maintain the moist state of the concrete surface, avoiding the inaccuracy and human error of manual adjustment. Especially in high temperature or dry environment, the system can automatically increase the airflow to avoid excessive evaporation of water, thereby ensuring the curing effect of concrete. This method not only improves the construction efficiency, but also effectively extends the service life of the concrete structure. In practical applications, the appropriate nozzle type and working mode can be selected in combination with different climatic conditions. For example, in low-temperature environments, nozzles with reduced spray volume can be used to reduce water loss; in high-humidity environments, high-efficiency nozzles can be selected to maintain appropriate airflow. The system can also integrate a climate prediction module to predict environmental changes in advance and make pre-adjustments.

[0043] In S1, the maintenance frame 1 is a telescopic structure that can be automatically adjusted according to the size of the beam bridge outer box. When the maintenance frame 1 is set in this method, the frame adopts a telescopic structure, and the size of the frame is automatically adjusted by an electric or hydraulic device. According to the actual measurement data, the telescopic structure will accurately adjust the height and width of the frame so that it can fit closely to the concrete surface. The telescopic structure of the frame is matched with the layout of the nozzle 2 to ensure that the nozzle can evenly spray airflow to cover the concrete surface. By adopting a telescopic structure, the maintenance frame can adapt to concrete of beam bridge outer boxes of different sizes, and has higher versatility and flexibility. The automatic adjustment function improves the efficiency of the maintenance process and avoids the error caused by manual adjustment. At the same time, the precise coordination of the nozzle 2 and the frame ensures the uniformity and consistency of the airflow during the maintenance process, thereby improving the maintenance quality and the durability of the concrete. The telescopic structure of this embodiment can be optimized according to different usage scenarios. For example, a pneumatic telescopic device or a hydraulic telescopic device can be used to more accurately control the change in frame size. In order to improve the stability of the equipment, the frame position can be monitored in real time in combination with a sensor to ensure that it is always in the best maintenance state.

[0044] The nozzle 2 is an adjustable angle nozzle, which can adjust the spray angle according to actual needs to ensure that the airflow evenly covers the concrete surface. In this embodiment, the nozzle 2 adopts an adjustable angle design, which can adjust the spray angle according to the actual situation of the concrete surface. By accurately adjusting the angle of the nozzle, the nozzle can ensure that the ejected airflow evenly covers the entire concrete surface, especially effectively curing the edges or difficult-to-reach areas. The adjustment of the nozzle angle can be controlled manually or electrically, and can even be designed to be automatically adjusted, and adaptively adjusted according to the monitored temperature and humidity data to ensure that the curing airflow is evenly distributed. The adjustable angle nozzle 2 significantly improves the uniformity of the airflow distribution, ensuring that the curing airflow can cover every area of ​​the concrete surface, avoiding the local insufficient or excessive wetting phenomenon that may be caused by traditional nozzles, thereby effectively improving the overall effect of concrete curing. In addition, the improvement of airflow uniformity can promote the uniformity of the concrete hydration process and reduce the cracks or uneven hardening problems that occur during the curing process. The adjustable angle nozzle 2 can adopt different types of adjustment mechanisms, such as electric rotation, pneumatic adjustment, mechanical gears, etc., to meet different usage requirements. In some complex maintenance environments, the nozzle can also be designed with an adaptive adjustment function to automatically adjust the angle according to the concrete surface shape or the humidity and temperature data fed back by the sensor to optimize the maintenance process. In addition, the nozzle spraying method can adopt micro-mist spray, atomizing nozzle and other methods to adapt to the airflow requirements in different environments.

[0045] The temperature and humidity sensor 3 is of wireless transmission type, which can transmit the monitoring data to the control module in real time to realize remote monitoring and adjustment. In this embodiment, the temperature and humidity sensor 3 adopts wireless transmission technology, which can collect the temperature and humidity data of the concrete surface and its surrounding environment in real time. The sensor sends the data to the central control module through the wireless network, and the control module adjusts the injection amount and angle of the airflow of the nozzle 2 according to the real-time data to ensure that the concrete surface is moist and meets the maintenance requirements. The wireless transmission function allows the operator to grasp the real-time situation of the maintenance process at any time through the remote device without on-site monitoring, and make corresponding adjustments. The temperature and humidity sensor 3 with wireless transmission greatly improves the automation and intelligence level of the maintenance process and reduces the need for on-site manual intervention. Through remote monitoring and adjustment, maintenance personnel can grasp the changes in the concrete maintenance environment in real time, make adjustments in time, and avoid quality problems caused by human factors or environmental changes during the maintenance process. In addition, wireless data transmission also facilitates unified scheduling and management of multiple locations and remote locations, saving time and cost of manual inspections. In addition to the wireless transmission function, the temperature and humidity sensor 3 can also be equipped with a cloud platform interface to upload data to the cloud in real time, which is convenient for data analysis and processing on a larger scale. The control module can be connected to mobile phones, tablets or PCs for remote real-time monitoring and adjustment. In some special applications, sensors can also be combined with other smart devices such as video surveillance and environmental sensing devices to achieve comprehensive management and automatic adjustment, further improving the accuracy and efficiency of the maintenance process.

[0046] Working process: First, according to the size of the bridge outer box concrete, adjust the height and width of the curing frame 1 to make it accurately adapt to the area to be cured. Then, multiple nozzles 2 are evenly arranged on the top of the curing frame 1 and connected to the air source through a rubber hose. The nozzles 2 can adjust the spray angle according to actual needs to ensure that the airflow evenly covers the concrete surface and its surrounding environment 2. At the same time, the temperature and humidity sensor 3 monitors the temperature and humidity of the concrete surface and its surrounding environment in real time, and transmits the monitoring data to the control module wirelessly. The control module automatically adjusts the air flow and angle of the nozzle 2 according to these real-time data to maintain an appropriate wet state, prevent excessive or insufficient evaporation of water, and ensure the curing effect of the concrete surface 6. This process greatly improves the curing efficiency and accuracy through automatic adjustment and intelligent monitoring.
