Description

TECHNICAL FIELD

[0001] The present application belongs to the field of mass concrete construction, and particularly relates to a temperature monitoring control system and method for mass concrete construction. BACKGROUND

[0002] Mass concrete temperature crack control is one of the common problems in the field of civil engineering. In the construction process of mass concrete structure, the hydration reaction of cement will produce a large amount of hydration heat, which will cause the internal temperature of the concrete to rise. When the temperature rises to the peak value, the temperature drops. In the process of temperature rise and drop, an uneven temperature field will be generated in the internal concrete. The external cold concrete is constrained by the expansion and contraction of the internal hot concrete, thereby generating temperature stress. When the stress exceeds the ultimate tensile strength of the concrete, cracks will be generated in the concrete, which will reduce the bearing capacity, waterproof performance and durability of the mass concrete, and affect the safety of the structure.

When the temperature drop data is greater than the second set temperature drop value, the pipe cooling circulation control module instructs the third temperature adjusting device to reduce the flow valve opening degree.

[0030] When the internal center temperature of the concrete is higher than the first set temperature value, the pipe cooling circulation control module starts the second temperature adjusting device to implement cooling. The second temperature sensor B collects the concrete temperature between the second temperature adjusting device and the third temperature adjusting device in real time and transmits it to the data analysis processing module for comparison with the concrete temperature at the previous time.

[0074] Embodiment 3

[0075] As shown in Figure 2 , Figure 3 and Figure 4 , the present application provides an embodiment of a temperature monitoring control method for mass concrete construction, comprising the following steps:

[0076] Step S1: The temperature wireless monitoring module collects concrete surface temperature and internal temperature data, and sends them to the wireless data acquisition communication module through wireless transmission, and the wireless data acquisition communication module transmits the temperature information to the data analysis processing module and the remote monitoring platform;

[0077] Step S2: The monitoring platform displays the temperature change of each monitoring point, and the data analysis processing module analyzes and calculates the temperature information, calculates the internal surface temperature difference and the highest internal temperature of the concrete, and automatically generates the corresponding temperature change curve, the data analysis processing module transmits the calculation result to the remote monitoring platform, and the data analysis processing module judges whether to instruct the warning module to alarm according to the calculation result;

[0078] Step S3: The curing module collects the internal temperature of the concrete, the temperature and humidity of the curing area, and the temperature of the surrounding environment, and sends them to the wireless data acquisition communication module through wireless transmission, and the wireless data acquisition communication module transmits the temperature and humidity information to the data analysis processing module and the remote monitoring platform, and the data analysis processing module judges the curing stage of the concrete according to the preset processing rule, and the curing module controls the intelligent curing machine to cure the concrete according to the analysis result of the data analysis processing module;

[0079] Step S4: In summer, when the concrete surface temperature is lower than the preset starting temperature at the completion of pouring, the pipe cooling circulation control module starts the first-stage temperature adjusting device to cool the peripheral part of the mass concrete, so as to avoid the external environment accelerating the internal temperature rise of the concrete; At the same time, the pipe cooling circulation control module starts the third-stage temperature adjusting device to implement cooling, so as to cool the hydration temperature rise of the concrete, the data analysis processing module calculates the temperature drop data, and adjusts the flow valve opening degree of the third-stage temperature adjusting device; When the internal center temperature of the concrete is higher than the first set temperature value, the pipe cooling circulation control module starts the second-stage temperature adjusting device to implement cooling, the data analysis processing module calculates the temperature drop data, and adjusts the flow valve opening degree of the second-stage temperature adjusting device; Through the multi-stage temperature adjusting device, the internal highest temperature of the concrete is reduced, so as to avoid the large tensile deformation of the concrete inside;

[0080] In winter, upon completion of pouring, when the concrete surface temperature is lower than the preset temperature, the pipe cooling circulation control module activates the primary temperature control device to raise the temperature of the outer part of the large-volume concrete, avoiding a large temperature difference between the inside and outside of the concrete, reducing temperature stress, minimizing heat diffusion on the concrete surface, and making the temperature gradient of the concrete more gradual, thus preventing cracks from forming. Once the concrete has fully set and hardened, the primary temperature control device is turned off. Simultaneously, the pipe cooling circulation control module activates the tertiary temperature control device to cool down the hydration temperature rise of the concrete. The data analysis and processing module calculates the temperature drop data and adjusts the opening of the flow valve of the tertiary temperature control device. When the internal core temperature of the concrete exceeds the first set temperature value, the pipe cooling circulation control module activates the secondary temperature control device to cool down, and the data analysis and processing module calculates the temperature drop data and adjusts the opening of the flow valve of the secondary temperature control device.

[0081] In step S2, when the temperature difference between the inner and outer surfaces exceeds 20°C, the warning module will sound an alarm; when the highest internal temperature exceeds 65°C, the warning module will sound an alarm.

In summer, when the internal core temperature of the concrete and / or the temperature and humidity of the curing area reach the summer spraying threshold, the curing module instructs the intelligent curing machine to perform spraying curing. In winter, when the temperature and humidity of the curing area and / or the temperature of the surrounding environment are lower than the winter steam temperature threshold, the curing module instructs the intelligent curing machine to perform steam curing. The remote monitoring platform can store the received working condition information. The backend can set up accounts with different permissions as needed, including management personnel accounts and user accounts, and grant different information query permissions to the accounts.

[0084] At the same time, the pipe cooling circulation control module starts the third temperature adjusting device to implement cooling, so as to prepare for the hydration temperature rise of the concrete; the third temperature sensor C collects the temperature of the center of the concrete in real time, and transmits the temperature to the data analysis processing module, and compares the temperature with the temperature of the center at the previous time, calculates the center temperature drop data, when the temperature drop data is less than the first set temperature drop value, the pipe cooling circulation control module instructs the flow valve of the third temperature adjusting device to increase the opening; when the temperature drop data is less than the second set temperature drop value and greater than the first set temperature drop value, the opening of the flow valve of the third temperature adjusting device is not adjusted; when the temperature drop data is greater than the second set temperature drop value, the pipe cooling circulation control module instructs the flow valve of the third temperature adjusting device to decrease the opening;

[0086] Through the multi-stage temperature adjusting device, the highest temperature in the concrete is reduced, so as to avoid the large tensile deformation in the concrete;

[0087] In winter, when the pouring is completed, the fourth sensor D detects the concrete surface temperature, which is transmitted to the data analysis processing module and compared with the preset starting temperature. When the concrete surface temperature detected by the fourth sensor D is less than the preset starting temperature, the pipe cooling cycle control module starts the first temperature adjusting device to heat the outer part of the mass concrete, so as to avoid the large temperature difference between the inside and the outside of the concrete, reduce the temperature stress, reduce the heat diffusion on the surface of the concrete, make the change of the concrete temperature gradient tend to be gentle, and prevent the concrete from cracking. The first temperature sensor A collects the concrete temperature between the concrete surface and the first temperature adjusting device in real time, which is transmitted to the data analysis processing module and compared with the concrete temperature at the previous time. When the temperature rise data is less than the first set temperature rise value, the pipe cooling cycle control module instructs the first temperature adjusting device to increase the flow valve opening degree. When the temperature rise data is less than the second set temperature rise value and greater than the first set temperature rise value, the flow valve opening degree of the first temperature adjusting device is not adjusted. When the temperature rise data is greater than the second set temperature rise value, the pipe cooling cycle control module instructs the flow valve opening degree of the first temperature adjusting device to decrease. Until the temperature detected by the temperature sensor A is equal to the preset temperature value, the first temperature adjusting device performs constant temperature control, so that the temperature detected by the temperature sensor A is always equal to the preset temperature value, until the concrete is hardened and solidified.

[0088] Preferably, the first set temperature rise value is 0.1°C, and the second set temperature rise value is 0.2°C.

[0089] The prior art considers that the early temperature difference of the concrete is large, which is easy to cause cracking, and the later temperature difference is small, which is not easy to crack, so at present, the control of the early temperature gradient is mainly emphasized, and the control of the later temperature difference is ignored.

[0090] Actually, the early hydration high temperature makes the internal free water vaporization produce pore pressure, which relieves the early shrinkage to some extent, so the early cracking of the concrete is not the most serious. On the contrary, in the later setting period, although the temperature difference becomes small, the shrinkage value of the concrete periphery becomes large, and cracking is more likely to occur. Therefore, the control of the later temperature difference cannot be ignored. Therefore, in winter, the first temperature adjusting device is used for heating and heat preservation to reduce the temperature difference between the inside and the outside of the concrete, until the concrete is hardened and solidified.

[0092] When the internal center temperature of the concrete is higher than the first set temperature value, the pipe cooling cycle control module starts the two-stage temperature adjusting device to implement cooling; the second temperature sensor B collects the temperature of the concrete between the two-stage temperature adjusting device and the three-stage temperature adjusting device in real time, and transmits the temperature to the data analysis processing module, compares the temperature with the temperature at the previous time, calculates the center temperature drop data, when the temperature drop data is less than the first set temperature drop value, the pipe cooling cycle control module instructs the flow valve opening of the two-stage temperature adjusting device to increase; when the temperature drop data is less than the second set temperature drop value and greater than the first set temperature drop value, the flow valve opening of the two-stage temperature adjusting device is not adjusted; when the temperature drop data is greater than the second set temperature drop value, the pipe cooling cycle control module instructs the flow valve opening of the two-stage temperature adjusting device to decrease.
