Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mass concrete curing, and particularly relates to an intelligent mass concrete energy-saving, emission-reducing and crack-preventing curing system and a mounting method. BACKGROUND

[0002] During the initial setting, final setting and curing of cement, a large amount of hydration heat is generated, and the hydration heat needs to be reasonably controlled in the engineering of pouring mass concrete structures (such as super high-rise buildings). Since the thermal conductivity of concrete is 1.28-2.33 W / m·K, the heat dissipation performance is extremely poor, the diurnal temperature difference is large in high-altitude and high-latitude regions and monsoon climate regions, the air moisture content is low, and the curing work of mass concrete is difficult to increase. The common causes of mass concrete cracks include unreasonable water-cement ratio, uneven shrinkage caused by excessive internal and external temperature difference, dry cracking caused by improper curing, settlement tension caused by excessive span, and long pouring interval. Among them, uneven shrinkage caused by excessive internal and external temperature difference is the main control difficulty in process control, and is also the main reason for the cracks of mass concrete. It is an urgent technical requirement to monitor the real-time temperature and curing humidity of mass concrete and give timely warning to regulate the internal temperature and curing humidity of concrete at the first time to ensure the internal and external temperature difference.

[0003] The negative effects of temperature shrinkage or dry-wet shrinkage cracks of reinforced concrete structures mainly manifest in corrosion of steel bars, loss of the role of steel bar protective layer, and thus failure to reach the structural strength index, resulting in structural damage. So far, the main measures to solve the problem of cracks caused by excessive internal and external temperature difference of mass concrete include adjusting the concrete mix proportion, adding rock powder and fly ash and other materials to reduce the hydration heat of concrete, controlling the heat dissipation of concrete to balance the overall temperature of the concrete structure, and laying more heat preservation structures such as geotextile and polyvinyl chloride film. The internal condensation pipe is erected and the surface is laid with heat and moisture preservation, so that the internal and external temperature difference is controllable, and the destructive cracks caused by the uncoordinated internal and external temperature shrinkage are prevented. In the process of engineering construction, the addition of fly ash and rock powder will reduce the strength of the concrete structure, but due to the low cost of the measures, they have been widely used, or they are often used together with the laying of heat preservation layer to reduce the overall hydration heat temperature and coordinate the internal and external temperature difference of concrete. However, this measure can only be used when the maximum internal temperature of concrete is below 70℃, and appropriate heat will be beneficial to the strength improvement of concrete after final setting. Excessive heat will cause the internal structure of concrete to denature after final setting, and lose its original strength index. When it is found through calculation that the maximum internal temperature of concrete will exceed 70℃ or more, a cooling system must be added to the center of the concrete structure to ensure that the maximum internal temperature does not exceed the maximum temperature required by the national standard.

[0004] But generally the center temperature of mass concrete construction is difficult to reach 70℃ and above, so the temperature crack control measures adopted by most projects are to add fly ash and rock powder and lay the external insulation layer of concrete structure for insulation. But if the external insulation layer is damaged during construction, or the concrete curing humidity of some areas does not meet the standard, then the temperature shrinkage cracks or dry shrinkage cracks will still be caused.

DETAILED DESCRIPTION

[0045] In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions of the present application are further described below in conjunction with the drawings and examples.

[0046] Example One:

[0047] Referring to the drawings Figures 1-4 ​The energy-saving and emission-reducing anti-crack intelligent maintenance system for mass concrete shown comprises a heat preservation layer 2 located on the outer side of the mass concrete structure 1, a waterproof layer 9 is arranged outside the heat preservation layer 2, and the waterproof layer 9 is made of a polyethylene waterproof film; a geotextile 3 is arranged between the mass concrete structure 1 and the heat preservation layer 2, and a maintenance water pipe 4 is arranged between the geotextile 3 and the heat preservation layer 2, a plurality of soaking holes 401 are formed in the side wall of the maintenance water pipe 4 close to the geotextile 3, and water in the maintenance water pipe 4 can be uniformly soaked on the geotextile 3 through the soaking holes 401.

[0048] Both ends of the maintenance water pipe 4 are communicated with temperature and humidity control assemblies, a plurality of temperature and humidity sensors 11 are installed on the geotextile 3, the temperature and humidity sensors 11 are in communication connection with corresponding temperature and humidity control assemblies, and a cooling water pipe 10 is further arranged in the mass concrete structure 1, and both ends of the cooling water pipe 10 are communicated with the maintenance water pipe 4.

[0049] Specifically, the temperature and humidity control assembly comprises a water storage tank 7, a water inlet pipe 6 is arranged in communication with the top of the water storage tank 7, water can be injected into the water storage tank 7 through the water inlet pipe 6, and it should be noted that the water storage tank 7 is arranged outside the mass concrete structure 1 in advance, a heater 8 and a GPRS temperature controller 5 are installed in the water storage tank 7, the temperature and humidity sensor 11 is in communication connection with the GPRS temperature controller 5, and the end of the maintenance water pipe 4 is located in the corresponding water storage tank 7.

[0050] The intelligent maintenance system further comprises a mobile client in communication connection with the temperature and humidity control assembly, the mobile client comprises a 4 / 5G mobile terminal and a PC processing terminal, and the start and stop of the entire maintenance system and the control of the temperature threshold setting can be controlled through the 4 / 5G mobile terminal and the PC processing terminal.

[0051] The corresponding cloud control system can be deployed in the mobile client, the cloud control system can collect the parameters of all temperature and humidity sensors in real time, compare the parameters with each group of preset threshold values, and perform accurate coordinate point early warning or alarm, and timely confirm whether maintenance measures such as repairing the heat preservation layer, heating or cooling maintenance cooling water are needed.

[0052] The temperature and humidity sensor 11 and the GPRS temperature controller 5 are powered by wired alternating current.

[0053] The specific working principle of the intelligent maintenance system in this invention is as follows: The intelligent maintenance system in this invention maintains the large-volume concrete structure 1 through the maintenance water pipe 4 and the cooling water pipe 10. The temperature and humidity sensor 11 provides real-time feedback on the temperature and humidity of the geotextile 3 surface. The GPRS temperature controller 5 uploads the information to the mobile client. The system makes corresponding maintenance or temperature control decisions based on the data analysis and processing. The water in the cooling water pipe 10 can enter two water storage tanks 7 through the maintenance water pipe 4. When the water temperature returned from the cooling water pipe 10 is insufficient, the heater 8 in the water storage tank 7 is activated to bring the water temperature to a suitable range before maintenance. When the water temperature returned from the cooling water pipe 10 is too high, cooling is performed, or a new, lower-temperature water source is added to the water storage tank 7 through the inlet pipe 6 for neutralization and cooling before maintenance.

[0054] During the curing process, the surface of the large-volume concrete structure 1 is evenly moistened through the wetting holes 401 of the curing water pipe 4 and the geotextile 3. The water in the cooling water pipe 10 absorbs the heat of hydration of the concrete and is transported by the water pump to the second water storage tank 7 (as shown in the attached image). Figure 1 The first step of the curing and cooling process is completed in the water storage tank 7 on the left side. The timing is set according to the scale of the pipeline system. Once the water level in the second water storage tank 7 reaches the target, the water pump direction is adjusted to make the internal cooling temperature field of the concrete more uniform. The water temperature is adjusted continuously based on the temperature and humidity monitor. During nighttime cooling, the water temperature is moderately heated to strictly control the temperature difference between the water delivered to the pipeline and the internal concrete temperature within 20℃. Temperature and humidity sensors 11 should be evenly distributed near the curing water pipe 4. The temperature and humidity sensors 11 and the GPRS temperature controller 5 can be connected either wired or wirelessly, depending on the site space. The temperature sensors inside the concrete are pre-installed by the construction party during construction. Using wired measurement point technology ensures low cost while effectively avoiding problems such as unstable wireless transmission caused by excessively high internal temperatures. The GPRS temperature controller 5 installed in the water storage tank can transmit temperature and air humidity data 24 hours a day without interruption. After the data is transmitted to the server, it can be viewed in real time through the website and mini-program. The server can group the data of the deep structure, the center of the structure, the middle layer of the deep structure and the concrete surface of the large volume concrete structure 1 separately, and set different safety alarm thresholds. It can also set early warning and alarm for the temperature rise and fall rate, the total increase value and the total decrease value of the curing cooling water, and file the early warning and emergency handling records with the on-site construction technical supervisor to ensure the system integrates monitoring, early warning, alarm and intelligent automatic curing.

[0055] In addition, each temperature and humidity sensor 11 in the application can be numbered and connected with the GPRS temperature controller 5, and the temperature and humidity sensor 11 is numbered to realize three-dimensional positioning, and the temperature measuring points are connected by fitting, that is, the temperature cloud chart of the overall structure is formed, the position where the temperature and humidity increase and decrease exceeds the standard is accurately positioned, and the temperature and humidity control measures are taken on the position.
