Description

Technical Field

[0001] This utility model relates to the field of road maintenance technology, specifically to a low-temperature concrete road maintenance device. Background Technology

[0002] Concrete is one of the most widely used materials in modern engineering, and its stable performance is crucial for ensuring the safety and progress of the entire project. However, in some northern regions, winters are long, or in high-altitude areas, temperatures are low. To meet the demands of rapid construction and shortened construction periods, it is necessary to carry out construction under cold conditions.

[0003] Newly poured concrete pavements face severe challenges in low-temperature environments. Concrete freezes at low temperatures, significantly slowing cement hydration and resulting in slow strength development, or even halting hydration altogether. This prevents the concrete from reaching its designed strength, severely impacting pavement quality and service life. Traditional concrete pavement curing methods, such as covering with insulation materials and watering, are ineffective in low-temperature environments and fail to meet the high-quality, high-efficiency requirements of modern road construction.

[0004] In view of the above, in order to overcome the above technical problems, this utility model designs a low-temperature concrete pavement curing device, which solves the above technical problems. Summary of the Invention

[0005] The technical objective of this invention is to provide a low-temperature concrete pavement curing device that can intelligently heat, insulate, and moisturize concrete pavements to improve the quality and efficiency of winter construction.

[0006] To achieve the above-mentioned technical objectives, this utility model provides the following technical solution: This utility model provides a low-temperature concrete pavement curing device, which is erected above the pavement to be cured and includes the following components: The support assembly includes pillars, side beams, and crossbeams. The pillars are installed perpendicular to the road surface to be maintained on both sides. Two side beams are respectively installed on the pillars on both sides. Multiple crossbeams are horizontally placed on the pillars on both sides and installed on the side beams. A heating assembly includes a heat insulation layer for heat insulation and a heating layer for heating, the heat insulation layer being laid and covering the outer surface of a support assembly, and the heating layer being disposed inside the heat insulation layer; An energy storage component, electrically connected to the heating layer, is used to supply power to the heating layer; The humidification component is electrically connected to the energy storage component and is located inside the heating layer to maintain the air humidity at over 95%. Among them, multiple temperature sensors are also installed on the support component and inside the insulation layer, and the temperature sensors are used to detect the temperature inside the insulation layer. The control component, electrically connected to the energy storage component, is used to regulate the preset values ​​of the moisturizing component and the temperature sensor.

[0007] Preferably, the heat insulation layer is a surface plastic film, and the heating layer is composed of electric heating elements, which are electrically connected to the energy storage component.

[0008] Furthermore, the surface of the heating element is covered with a waterproof material; the heating element is connected to the bottom of the crossbeam by suspension or binding with thin iron wire.

[0009] Preferably, the support column is tubular; the support column, side beam, and crossbeam are all hollow aluminum structures.

[0010] Based on the above-mentioned preferred embodiment, the side beam is a cylinder and is in contact with the inner side of the insulation layer.

[0011] Preferably, the humidification component includes a humidifier and a humidity meter. The humidifier is a miniature industrial spray humidifier in the shape of a tube. Both the humidifier and the humidity meter are mounted on a crossbeam and their values ​​are regulated by a control component.

[0012] More preferably, a plurality of the humidifiers are mounted on the crossbeam at the central position.

[0013] The control components include a console and a display. The console is electrically connected to the humidifier and the temperature sensor. The display is used to visualize the data from the console.

[0014] Furthermore, the console is also electrically connected to an alarm.

[0015] The energy storage component includes a solar panel and a battery. The solar panel is laid on a support component and is electrically connected to the battery.

[0016] The beneficial effects of this utility model are as follows: 1. This utility model constructs a closed, insulated space by erecting a support assembly consisting of pillars, side beams, and crossbeams above a concrete pavement, covering it with an insulation layer on the outside, and setting up a heating layer and a temperature and humidity control system inside. This allows for constant temperature heating and humidity maintenance of concrete in low-temperature construction environments, significantly improving the hydration reaction rate of concrete, preventing early freezing and cracking, and thus solving the problems of difficult temperature and humidity control, slow strength growth, and low construction quality in concrete curing during winter or in high-altitude areas.

[0017] 2. The heating layer of this utility model uses waterproof wrapped electric heating elements, which are fixed to the bottom of the crossbeam by suspension or binding. This ensures that the heating source can be evenly distributed in the middle of the curing space, while avoiding direct contact with the concrete surface or water accumulation. This ensures the electrical safety and heating uniformity of the device during use, and effectively solves the problems of complex layout, uneven heating and easy short circuit of traditional heating devices.

[0018] 3. The control component of this utility model is electrically connected to a temperature sensor, an electric heating element, a hygrometer, and a humidifier component. It uses a control console to adjust the temperature and humidity in real time and visualizes the parameters on a display. At the same time, an alarm device is set to monitor system abnormalities, making the adjustment of maintenance parameters more precise and the operation more convenient. It can respond promptly to temperature and humidity fluctuations and fault conditions, thereby further improving the level of intelligence and construction safety of concrete curing.

Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0020] The above and other aspects of the present invention will now be described by way of example only, with reference to the accompanying drawings, in which: Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0022] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0023] Example 1: like Figure 1 As shown, in this embodiment, a certain amount of water is sprayed on the freshly poured concrete pavement to allow time for the erection of the support components, thus preventing the concrete from failing to cure in a timely manner during this period. The prepared tubular supports 1 are symmetrically erected along the pavement to be cured, that is, there is one support 1 at the same position on both sides of the pavement, so as to facilitate the erection of the crossbeam 3.

[0024] In this embodiment, a set of support columns 1 are erected every 50cm. Side beams 2 are erected on adjacent support columns 1 along the road. The length of the crossbeams 3 is determined according to the road width and the crossbeams 3 are erected across the road. All beams are aluminum hollow tube structures and are connected by welding to form a rigid frame structure to form a support component.

[0025] After the support components are erected, the other internal components are installed. First, a suitable heating element 51 is selected according to the actual construction conditions. In this embodiment, a heat resistance wire wrapped in waterproof material is used to form a long cable-like structure, which is suspended or tied to the crossbeam 3.

[0026] In this embodiment, a miniature industrial spray humidifier is selected as the humidifier 6 required for maintenance and moisturization. The humidifier 6 has a tubular structure and is installed under the crossbeam 3 using a connection method similar to that of the electric heating element 51.

[0027] It should be noted that all electrical connections in this embodiment are wrapped in waterproof material and embedded in the hollow support assembly. In this embodiment, the hygrometer 8 is connected under the central road section crossbeam 3. If the road section is too long, exceeding 20m, multiple hygrometers 8 are considered to reduce errors. The hygrometer 8 is electrically connected to the control console 9. The humidifier 6 and the hygrometer 8 together form a humidification device.

[0028] In this embodiment, multiple heating elements 51 are arranged to form a heating layer 5, which heats the road surface and maintains the temperature at 30-40 degrees Celsius to ensure that the road surface temperature is suitable. Multiple temperature sensors 7 are also installed inside the heating layer 5. The temperature sensors 7 are thermistors and are electrically connected to the control console 9.

[0029] Example 2: Based on the above embodiments, after the internal structure of the support component is laid out, a heat insulation layer 4 is added to its outer side. The heat insulation layer 4 has a layered structure, and in this embodiment, the material is polyvinyl chloride. After the internal structure is laid out, a solar panel 11 is then installed on the heat insulation layer 4. The solar panel 11 is electrically connected to the battery 12 to form an energy storage component, so that the entire device can be powered without an external power source under sufficient sunlight conditions.

[0030] Example 3: Based on Embodiments 1 and 2 above, the control console 9 in this embodiment is equipped with a display screen to monitor the device's operation and is powered by the storage battery 12. This embodiment also connects an alarm 10 to the control console 9. The alarm 10 specifically includes an indicator light and a buzzer. When the equipment malfunctions, such as when the maintenance temperature is too high or too low and the device cannot adjust automatically, the control console 9 will adjust the settings based on data collected by the temperature sensor 7 and the humidity meter 8, activating the alarm 10 immediately for easy detection and repair.

[0031] Specifically, in this embodiment, the temperature sensor 7 is disposed between the heating layers 5 to facilitate timely monitoring of the temperature and determination of whether to change the operating status of the heating device. If the temperature is about to reach the maintenance standard, heating needs to be stopped in time.

[0032] It is important to note that the appropriate insulation layer material should be selected first based on the site conditions, then the support components should be laid on the road surface to cover the entire road surface, and then other components should be added on top of it.
