Description

Technical Field

[0001] This invention relates to the field of large-volume concrete curing technology, specifically to an intelligent large-volume concrete curing cover that regulates temperature and humidity and its construction method. Background Technology

[0002] Mass concrete refers to large-volume concrete structures with a minimum geometric dimension of 1 meter or more, or concrete that is expected to develop harmful cracks due to temperature changes and shrinkage caused by the hydration of cementitious materials. Mass concrete construction is frequently involved in modern building construction, such as the foundations of high-rise buildings, the foundations of large equipment, and hydraulic dams.

[0003] After concrete is poured, it releases a large amount of heat during hydration. Due to the temperature difference between the inside and outside, the heat inside the concrete accumulates and is not easily dissipated. When the temperature difference becomes large enough, the tensile stress on the surface exceeds the ultimate tensile strength of the concrete at that time, and cracks will appear on the concrete surface. Therefore, during the construction of large-volume concrete, it is necessary to monitor the temperature difference in real time to prompt the construction site to take measures to reduce the temperature difference and ensure that the temperature difference that leads to cracking does not occur.

[0004] The current traditional method for curing large-volume concrete involves covering the concrete surface with a plastic film for moisture retention, covering it with straw bags for insulation, and finally covering it with geotextile to reduce convection and prevent cracking caused by dryness or excessive ultraviolet radiation. However, the materials used in this traditional method are not recyclable, are not energy-efficient or environmentally friendly, easily pollute the environment, and generate large amounts of construction waste.

[0005] Currently, temperature measurement for large-volume concrete is mainly conducted manually. First, temperature measurement holes are pre-drilled inside the concrete. Personnel use thermometers to measure the temperature in each hole, and the results are manually compiled and analyzed before appropriate measures are taken to control temperature variations within the concrete. This method has the following problems: temperature information requires manual collection, which is labor-intensive. Furthermore, considering the long construction period of large-volume concrete, manual methods cannot provide real-time temperature control. Manual temperature measurement is inefficient, and the temperature difference results are often delayed, failing to reflect the true internal temperature differences of the concrete, frequently leading to unsatisfactory temperature control in large-volume concrete. Summary of the Invention

[0006] The main objective of this invention is to provide an intelligent large-volume concrete curing cover that regulates temperature and humidity, and its construction method, in order to solve the above-mentioned problems.

[0007] To achieve the above objectives, the present invention provides an intelligent large-volume concrete curing cover for regulating temperature and humidity, comprising: an acrylic plate, a curing cover base plate, an electric heating wire device, and a water pipe channel; wherein, the curing cover base plate is supported above the large-volume concrete; the acrylic plate is installed on the top of the curing cover base plate, the electric heating wire device is installed on the inner side of the curing cover base plate, the water pipe channel is laid on the periphery of the bottom end of the curing cover base plate, and an atomizing nozzle is installed at the bottom end of the water pipe channel.

[0008] Furthermore, it also includes a temperature-sensing optical fiber, a cabinet-type distributed optical fiber temperature demodulator, and a remote terminal device; the temperature-sensing optical fiber is deployed inside the large-volume concrete, and the temperature-sensing optical fiber is connected to the remote terminal device through the cabinet-type distributed optical fiber temperature demodulator.

[0009] Furthermore, it also includes a humidity sensor and a wireless communication module. Both the humidity sensor and the wireless communication module have second bolt holes. The humidity sensor and the wireless communication module are respectively connected to the base plate of the maintenance cover by two second bolts passing through the second bolt holes. The humidity sensor is connected to the remote terminal through the wireless communication module.

[0010] Furthermore, it also includes a heating wire reflector, wherein a third bolt hole is provided on the inner side of the bottom plate of the curing cover, the heating wire reflector is fixed to the third bolt hole by the third bolt, and the heating wire device is disposed at the bottom end of the heating wire reflector.

[0011] Furthermore, it also includes water pipe hooks. The bottom plate of the maintenance cover has water pipe hook holes, the water pipe hooks are connected to the bottom plate of the maintenance cover through the water pipe hook holes, and the water pipe channels are hung on the water pipe hooks.

[0012] Furthermore, it also includes a water storage tank, which is connected to the inlet of the water pipe channel via a water pump.

[0013] Furthermore, the inner side of the base plate of the maintenance cover is provided with multiple support connecting frames, and each support connecting frame is connected to a support.

[0014] A construction method for an intelligent large-volume concrete curing cover that regulates temperature and humidity includes the following steps:

[0015] S1. Before pouring, install temperature-measuring optical fibers inside the large-volume concrete.

[0016] S2. After pouring, an intelligent large-volume concrete curing cover is spliced ​​and installed on the surface of the large-volume concrete.

[0017] S3. The temperature information transmitted by the temperature measuring fiber is demodulated to the remote terminal device through the cabinet-type distributed fiber optic temperature demodulator; the humidity information is transmitted to the remote terminal device through the humidity sensor and wireless communication module embedded in the curing cover.

[0018] S4. Based on the detected temperature difference between the inside and outside of the concrete and the humidity of the concrete surface, the system adjusts in a timely manner through remote terminal equipment, automatically starting and stopping the electric heating wire device to heat the concrete and the atomizing nozzle to spray moisture according to the preset temperature and humidity thresholds.

[0019] Furthermore, the peripheral temperature-measuring optical fibers of the large-volume concrete section are 40mm to 100mm away from the concrete surface, and no less than 4 temperature-measuring optical fibers are vertically installed in each section, with the spacing between the vertical temperature-measuring optical fibers being between 0.4m and 1.0m.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention enables intelligent acquisition of temperature and humidity information for large-volume concrete, automating information processing and control. Utilizing temperature-sensing optical fibers, it replaces manual temperature and humidity measurement and collection with intelligent information acquisition, overcoming many drawbacks of manual methods while saving labor resources.

[0022] 2. This curing cover is primarily made of acrylic sheets, allowing sunlight to pass through effectively and utilizing the greenhouse effect to provide solar energy for heating the concrete surface to a certain extent. Simultaneously, based on temperature information collected by temperature-sensing optical fibers and humidity information collected by humidity sensors embedded within the curing cover, the heating wire device and atomizing nozzles are activated and deactivated according to preset temperature and humidity thresholds. Precise heating and humidification spraying within the area are achieved using remote terminal equipment. This avoids the waste of water and labor resources associated with large-area watering in the curing of large-volume concrete, while effectively solving the problem of low efficiency in traditional curing methods.

Detailed Implementation

[0030] To achieve the above objectives and effects, the technical means and structure adopted by the present invention will be described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of the present invention.

[0031] This invention can dynamically adjust and automatically start and stop heating measures and humidification spraying based on temperature and humidity information using remote terminal equipment, thereby achieving intelligent sensing and precise control of the curing of large-volume concrete.

[0032] like Figure 1-3 As shown, this invention provides an intelligent large-volume concrete curing cover for regulating temperature and humidity, comprising: an acrylic plate 1, a curing cover base plate 2, an electric heating wire device 3, and a water pipe channel 4; wherein, the curing cover base plate 2 is supported above the large-volume concrete; the acrylic plate 1 is installed at the top of the curing cover base plate 2, the electric heating wire device 3 is installed on the inner side of the curing cover base plate 2, the water pipe channel 4 is laid on the periphery of the bottom end of the curing cover base plate 2, and eight atomizing nozzles 42 are installed at the bottom end of the water pipe channel 4.

[0033] Acrylic sheet 1 is placed directly above the base plate 2 of the curing cover. Both sheets have eight first bolt holes 11 in total, two on each side. First bolts 12 pass through the first bolt holes 11 to connect and fix the two sheets. Acrylic sheet 1 has good plasticity and is easy to process, so it is convenient to replace it in time when damaged. Acrylic sheet 1 has strong durability and high surface strength. It has good light transmission performance, which can effectively transmit sunlight and utilize the greenhouse effect to provide solar energy to the concrete surface for heating to a certain extent, thus saving resources.

[0034] like Figure 4-5 As shown, the present invention also includes a temperature-measuring optical fiber 5, a cabinet-type distributed optical fiber temperature demodulator 6, and a remote terminal device 7; the temperature-measuring optical fiber 5 is deployed inside the large-volume concrete, and the temperature-measuring optical fiber 5 is connected to the remote terminal device 7 through the cabinet-type distributed optical fiber temperature demodulator 6.

[0035] The present invention also includes a humidity sensor 25 and a wireless communication module 26. Both the humidity sensor 25 and the wireless communication module 26 are provided with second bolt holes 28. The humidity sensor 25 and the wireless communication module 26 are respectively connected to the base plate 2 of the maintenance cover by two second bolts 27 passing through the second bolt holes 28. The humidity sensor 25 is connected to the remote terminal through the wireless communication module 26 and can transmit humidity information to the remote terminal device 7.

[0036] The present invention also includes a heating wire reflector 31, wherein a third bolt hole 29 is provided on the inner side of the base plate 2 of the curing cover, the heating wire reflector 31 is fixed on the third bolt hole 29 by a third bolt 32, and the heating wire device 3 is disposed at the bottom end of the heating wire reflector 31.

[0037] Three sets of heating wire devices 3 are provided, located inside the heating wire reflector 31 and fixed to the third bolt hole 29 by the third bolt 32, thus connecting to the base plate 2 of the curing cover. The heating wire devices 3 are activated and deactivated based on the temperature information fed back by the temperature-measuring fiber optic 5 and a preset temperature threshold. For example, when the temperature difference between the inside and outside of the concrete is greater than 25℃, the heating wire devices 3 are activated to heat the concrete surface; when the temperature difference is less than 18℃, the heating wire devices 3 are deactivated. The heating wire reflector 31 is made of polished stainless steel, which reduces the heat transferred from the heating wire devices 3 to the upper acrylic plate 1 and allows more heat to radiate to the concrete below, thus better insulating the concrete. However, the heat resistance of the acrylic plate 1 is not excellent; if it is exposed to temperatures exceeding 60℃ to 95℃ for a long period, it is prone to slight deformation. Therefore, the heating temperature of the heating wires should not be too high.

[0038] The present invention also includes a water pipe hook 24. The base plate 2 of the maintenance cover is provided with water pipe hook holes 23. There are a total of sixteen water pipe hook holes 23, four of which are provided on each side. The water pipe hook 24 is connected to the base plate 2 of the maintenance cover through the water pipe hook holes 23. The water pipe channel 4 is hung on the water pipe hook 24.

[0039] The invention also includes a water storage tank 8, which is connected to the inlet 41 of the water pipe channel 4 via a water pump. The inlet 41 of the water pipe channel 4 is connected to the water pipe leading out from the water storage tank 8, realizing parallel connection between the water circuits of each maintenance cover. The remote terminal device 7 can start and stop the water pump to perform humidification spraying operation based on the feedback humidity information.

[0040] In this embodiment, the inner side of the base plate 2 of the maintenance cover is provided with four support connecting frames 21, and each support connecting frame 21 is connected to a support 22.

[0041] This invention also provides a construction method for an intelligent large-volume concrete curing cover that regulates temperature and humidity, comprising the following steps:

[0042] S1. Before pouring, install temperature measuring optical fibers 5 inside the large volume concrete.

[0043] S2. After pouring, an intelligent large-volume concrete curing cover is spliced ​​and installed on the surface of the large-volume concrete.

[0045] S4. Based on the detected temperature difference between the inside and outside of the concrete and the humidity of the concrete surface, the remote terminal device 7 is used to adjust in a timely manner, and the electric heating wire device 3 is automatically started and stopped according to the preset temperature and humidity thresholds to heat and the atomizing nozzle 42 is used for moisturizing spraying.

[0046] In this embodiment, the peripheral temperature measuring optical fiber 5 of the large-volume concrete section is 40mm to 100mm away from the concrete surface. There are no less than 4 temperature measuring optical fibers 5 vertically arranged in each section, and the arrangement spacing of the vertical temperature measuring optical fibers 5 is between 0.4m and 1.0m.

[0047] This invention enables intelligent collection of temperature and humidity information for large-volume concrete, automating information processing and control. Utilizing temperature-sensing optical fibers, intelligent information acquisition replaces manual temperature and humidity measurement and collection, overcoming numerous drawbacks of manual methods and saving labor resources. The curing cover, primarily made of acrylic sheets, effectively transmits sunlight, utilizing the greenhouse effect to provide solar energy for heating the concrete surface. Simultaneously, based on temperature information collected by the temperature-sensing optical fibers and humidity information collected by the humidity sensor embedded within the curing cover, and according to preset temperature and humidity thresholds, the heating wire device and atomizing nozzles are activated and deactivated. Precise heating and humidification spraying within the area are achieved using remote terminal equipment. This avoids the waste of water and labor resources associated with large-area watering in the curing of large-volume concrete, while effectively solving the problem of low efficiency in traditional curing methods. The curing cover is easy to assemble, can be reused multiple times, and aligns with the green concept of environmental protection and energy conservation.

[0048] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
