Description

Technical Field

[0001] The invention belongs to the technical field of concrete structure construction, and in particular relates to a winter construction and maintenance system for a large-volume concrete structure based on energy conservation. Background Art

[0002] With the continuous development of social economy and the continuous advancement of construction, the scale and scope of construction projects in my country are also increasing. As the construction area continues to expand to the low latitudes and high altitudes in the north, the temperature difference between day and night in the construction site environment is very large, and the temperature is low throughout the year. Especially after entering winter, the construction technology level of the large-volume concrete structure of the foundation part is increasingly required.

[0003] Concrete is essentially a composite material, mainly composed of adhesives, aggregates, water and additives. It is widely used in the field of construction engineering due to its excellent compressive strength and durability. However, the temperature difference between day and night in the north and high-altitude areas is very large, and the temperature is generally low throughout the year. This extreme climatic condition has a serious impact on the solidification and hardening process of concrete, which may lead to an increase in project costs and delays in project progress.

[0004] In low temperature environments, the time required for the water inside the concrete to freeze is shortened, and the expansion of ice may cause the internal structure of the concrete to freeze and crack. At the same time, the time for the concrete to solidify and harden increases, which can easily lead to a series of problems such as damage to the internal structure due to freezing and cracking, and a significant reduction in bearing capacity and durability.

[0005] Concrete materials act as adhesives through the hydration of cement materials in them. Once the temperature drops below 0°C, the hydration reaction will almost stagnate or progress very slowly, which will affect the setting and hardening of concrete.

[0006] As the temperature continues to drop, the water inside the concrete begins to freeze into ice. In extreme cases, when all the water inside the concrete freezes into ice, it will cause the concrete to expand and generate tensile stress inside the concrete, causing damage to the concrete structure. The frozen water will also affect the aggregate sand and gravel in the concrete, causing a large number of ice crystals to adhere to the surface of the aggregate. This will further reduce the bond between the concrete and the sand and gravel, and seriously weaken the overall bearing capacity of the concrete structure.

[0007] At present, the common winter construction and maintenance methods for concrete mainly include: adding antifreeze, preheating concrete mix materials, heat storage maintenance, steam insulation, etc.

[0008] The basic principle is to preheat the various parts of the concrete to ensure that the temperature difference between the inside and outside of the concrete structure is kept low during the curing stage, so as to reduce the possibility of temperature shrinkage cracks or even damage, and ensure that the concrete structure solidifies and hardens smoothly, and that all performance indicators are normal. A slight deviation in the control of the construction environment temperature may cause cracks in the concrete, and most heating methods require a lot of additional energy consumption.

[0009] Therefore, in order to solve the above problems, it is necessary to design a winter construction and maintenance system for large-volume concrete structures based on energy saving. Summary of the invention

[0010] The technical problem to be solved by the present invention is to solve the deficiencies in the prior art and design a new winter construction and maintenance system for large-volume concrete structures based on energy conservation. This winter construction and maintenance system for large-volume concrete structures based on energy conservation has a perfect structure. It adopts multi-dimensional three-dimensional thermal insulation technology based on energy conservation and utilizes low-boiling-point working fluids pre-arranged in the embedded pipes to absorb the heat released by cement hydration inside the large-volume concrete. The low-boiling-point working fluids are heated and vaporized to form a hot steam environment. The installed environmental temperature and humidity real-time monitoring automatic control device is used to supplement a certain amount of hot steam into the steam delivery pipeline. The comprehensive guarantee is achieved that the temperature difference between the inside and outside of the large-volume concrete structure is reduced to a safe value to reduce the possibility of temperature shrinkage cracks and ensure the insulation effect of the large-volume concrete structure in the winter construction and maintenance stage.

[0076] like Figure 1-Figure 8The present invention proposes a winter construction and maintenance system for large-volume concrete based on energy conservation. It adopts multi-dimensional three-dimensional thermal insulation technology based on energy conservation, comprehensively utilizes the heat release effect of cement hydration in the concrete structure itself, and supplements the heat circulation medium based on the steam curing method, thereby maintaining the temperature difference between the inside and outside of the structure of large-volume concrete during the curing stage, avoiding temperature shrinkage cracks and even damage caused by excessive temperature difference between the inside and outside of the concrete structure. Finally, the energy conservation and thermal insulation effect of winter construction of large-volume concrete structures is achieved.

[0077] Embodiment 1:

[0078] Specifically, Figure 1 , Figure 3 and Figure 8 As shown, it includes a concrete mold 1 and an insulation covering ceiling 2. Conventional concrete pouring and formwork technology is used to pour the foundation mass concrete into the concrete mold 1. The insulation covering ceiling 2 covers the opening position of the concrete mold 1. The two together form a closed space, which wraps the foundation mass concrete inside, ensuring that the foundation mass concrete is placed in a closed space with a constant temperature.

[0079] The concrete mold 1 is a rectangular frame with an opening on the upper side, which provides an entrance for the basic large-volume concrete structure to enter the concrete mold 1.

[0080] The thermal insulation covering ceiling 2 covers one side of the opening of the concrete mold 1, and the thermal insulation covering ceiling 2 is used to make the concrete mold 1 as a whole into an enclosed space. In such a closed environment, the impact of external temperature fluctuations on the internal temperature of the concrete can be effectively reduced, thereby accelerating the hardening speed of the concrete and improving the overall strength and quality of the concrete. In addition, the use of the thermal insulation covering ceiling 2 can also reduce the evaporation of water to a certain extent and maintain the moisture of the concrete during the hardening process, which is very important for avoiding cracking of the concrete surface and ensuring the quality of the final product. In summary, the application of the thermal insulation covering ceiling 2 not only improves the use efficiency of the concrete mold 1, but also provides strong support for ensuring the quality of concrete construction.

[0081] A curing chamber 1-1 and a drainage channel 1-2 are arranged inside the concrete mold 1. The concrete mold 1 is provided with prefabricated holes 1-3 for draining water from the drainage channel 1-2.

[0082] Curing room 1-1 is used for curing the foundation mass concrete structure and maintaining the shape of the foundation mass concrete structure.

[0083] In the hot steam curing environment, condensed water is easily formed on the surface of the concrete mold 1 and the thermal insulation covering material. If the condensed water is not discharged in time, it will accumulate between the mold and the covering material, causing adverse effects on the curing environment of the concrete.

[0084] Therefore, drainage channels 1-2 are designed mainly to discharge condensed water generated in the curing environment to prevent water from converging into the salt lake room, while maintaining the overall environmental temperature and humidity during the curing phase of the large-volume concrete structure of the foundation.

[0085] A connecting pipe 1-2-1 is provided on the side of the concrete mold, and the fixed position of the connecting pipe 1-2-1 corresponds to the position of the drainage channel 1-2; water is discharged through the connecting pipe 1-2-1 to prevent the water in the drainage channel 1-2 from being not completely drained.

[0086] A fixing groove 1-1-1 and a pre-buried pipe 1-1-2 are provided in the curing chamber 1-1; the pre-buried pipe 1-1-2 is fixed in the fixing groove 1-1-1; the fixing groove 1-1-1 is used to place the pre-buried pipe 1-1-2, and the pre-buried pipe 1-1-2 extends into the bottom of the curing chamber 1-1 to prevent the pre-buried pipe 1-1-2 from collapsing when pouring concrete.

[0087] The wall thickness of the embedded pipe 1-1-2 is precisely calculated and designed to ensure that its strength can meet the internal pressure during the pouring of the large-volume concrete structure of the foundation; the embedded pipe 1-1-2 is prevented from being squeezed and deformed by the internal pressure during the pouring of concrete, thereby ensuring the stability and reliability of the embedded pipe in the concrete structure and avoiding structural safety hazards caused by deformation.

[0088] The embedded pipe 1-1-2 is provided with a receiving cavity, and a low-boiling-point working fluid is arranged in the receiving cavity. During the concrete curing process, temperature fluctuation is one of the key factors affecting the quality of concrete. Therefore, the embedded pipe 1-1-2 is provided with a low-boiling-point working fluid, which can respond quickly to temperature changes, evaporate or condense quickly, thereby absorbing or releasing a large amount of heat, reducing temperature fluctuations, and providing a more stable curing environment for concrete.

[0089] The low-boiling-point working medium pre-filled in the embedded pipe 1-1-2 is a special material. After it is heated and vaporized, it evaporates into the interior of the concrete mold 1 to supplement the hot steam and form a hot steam environment. After it is cooled to below the boiling point, it liquefies into a low-boiling-point liquid working medium, part of which can cover the outside of the large volume concrete to form a protective layer to maintain the curing temperature of the large volume concrete.

[0090] The heat released by the internal cement hydration during the solidification process of the mass concrete of the foundation is utilized to heat the low-boiling-point working fluid liquid in the embedded pipe 1-1-2 and vaporize it, so as to form a hot steam environment under relatively winter construction conditions, so as to avoid the phenomenon of cement segregation and non-condensation on the outer surface of the mass concrete of the foundation caused by the low temperature environment.

[0091] At the same time, the low-boiling-point working medium in the embedded pipe 1-1-2 can also take away part of the heat released by cement hydration inside the foundation mass concrete when it vaporizes, so as to keep the temperature difference between the inside and outside of the foundation mass concrete structure at a low level as much as possible, and avoid the phenomenon of temperature shrinkage and cracking of the mass concrete caused by excessive temperature difference between the inside and outside. At the same time, the vaporized low-boiling-point working medium forms hot steam to supplement the hot working medium required for the steam curing method, so as to achieve the purpose of energy saving.

[0092] Embodiment 2:

[0093] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and 7 As shown, on the basis of Example 1, in order to make the temperature inside the concrete mold 1 controllable, an environmental temperature and humidity real-time monitoring device 1-4 is provided inside the concrete mold 1.

[0094] The real-time monitoring device 1-4 of environmental temperature and humidity is arranged in the concrete mold 1 to monitor the temperature and humidity changes of the construction environment in real time, and compares them with the temperature and humidity required for the curing of large-volume concrete. It is connected to the controller so that the internal temperature of the concrete mold 1 can be remotely observed. If the control console staff remotely finds that the temperature in the concrete mold 1 does not meet the curing conditions, they can send instructions to the on-site staff, and the on-site staff inputs sufficient steam from the outside to adjust the temperature inside the concrete mold 1 so that the temperature inside the concrete mold 1 meets the curing conditions.

[0095] Preferably, a real-time monitoring device 1-4 for ambient temperature and humidity that can automatically alarm can also be selected. When the on-site staff detects the alarm, they can take immediate action and input sufficient steam from the outside of the concrete mold 1 into the inside in time, which reduces the time for the console staff to send instructions to the on-site staff and improves work efficiency.

[0096] The environmental temperature and humidity real-time monitoring device 1-4 is remotely connected to a controller, which receives the data detected by the environmental temperature and humidity real-time monitoring device 1-4 and converts the data into a readable format. After the conversion, it is determined whether the current vertical temperature and humidity thresholds meet the maintenance requirements. If it meets the requirements, it continues to be observed. If not, it controls the steam delivery pipeline 2-1-1 to open and supplement steam.

[0097] Specifically, the minimum value of the temperature and humidity thresholds that meet the maintenance requirements can be set to 15°C, and the maximum value can be set to 20°C.

[0098] Embodiment 3:

[0099] like Figure 4-7As shown, on the basis of Example 2, in order to make the internal temperature of the concrete mold 1 adjust itself and always maintain it within the temperature and humidity thresholds, steam is input through an external delivery pipeline so that the indoor temperature can be adjusted arbitrarily.

[0100] Specifically, the heat-insulating covering ceiling 2 is provided with a connecting hole 2-1, and a steam delivery pipe 2-1-1 is connected to the connecting hole 2-1. Through the external steam delivery pipe, the amount of steam input into the mold can be accurately controlled, thereby achieving accurate regulation of the internal temperature of the mold.

[0101] The steam delivery pipeline 2-1-1 is connected to the environmental temperature and humidity monitoring device in real time through the controller. The specific temperature and humidity thresholds can be pre-set on the controller console. When the actual temperature and humidity exceed the set range, the system will automatically adjust the steam input to ensure that the temperature and humidity inside the mold always remain in an ideal state.

[0102] According to the data detected by the real-time monitoring device 1-4 for ambient temperature and humidity, the logic judgment module of the console determines whether it is necessary to open the steam delivery pipeline 2-1-1. If it is necessary to open it, the steam delivery pipeline 2-1-1 will deliver high-temperature hot steam to the concrete mold 1, and work together with the hot working medium steam released from the embedded pipe 1-1-2 to provide the temperature environment required for the curing of large-volume concrete. A stable temperature and humidity environment is formed, which is conducive to the uniform hardening of concrete and avoids uneven stress and cracks in the concrete caused by temperature fluctuations. The steam delivery pipeline 2-1-1 is automatically controlled to open for supplementation, which promotes the completion of thermal insulation curing of large-volume concrete.

[0103] The steam delivery pipeline 2-1-1 is provided with an electric valve 2-1-2; the electric valve 2-1-2 is remotely connected to the controller. The controller sends a command, the electric valve 2-1-2 receives the command and opens, and the steam delivery pipeline 2-1-1 delivers steam to the inside of the concrete mold 1, so that the temperature inside the concrete mold 1 can be remotely controlled.

[0104] Embodiment 4:

[0105] On the basis of Example 1, in order to prevent water backflow, a check valve is provided in the connecting pipe 1-2-1 to prevent water from returning to the drainage channel 1-2.

[0106] Condensed water caused by low temperature in the curing environment flows out through the drainage channel 1-2, avoiding water accumulation in the mold, thereby reducing the risk of concrete quality degradation due to excessive water. At the same time, the check valve is set to ensure that the condensed water can only flow out in one direction, preventing external water or impurities from flowing back into the concrete mold 1 through the drainage channel 1-2.

[0107] Embodiment 5:

[0108] like Figure 1, Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, on the basis of Example 1, the structure of the embedded pipe 1-1-2 is further defined. Specifically, one end of the embedded pipe 1-1-2 fixed in the fixing groove 1-1-1 is closed, and the other end of the embedded pipe 1-1-2 is open. This allows the low-boiling-point working fluid in the embedded pipe 1-1-2 to only go out from the open side after vaporization and enter the internal space of the concrete mold 1, forming a steam environment.

[0109] Embodiment 6:

[0110] On the basis of Example 1, sealing pads are provided at the contact positions between the concrete mold 1 and the heat-insulating cover ceiling 2 to prevent the entry of external air.

[0111] Embodiment 7:

[0112] On the basis of Example 3, the controller module is further limited, and the controller at least includes a data processing module, a logic judgment module, an early warning module and a new information transmission module. After the data processing module receives and processes the data, the logic judgment module determines whether the current temperature and humidity in the curing room 1-1 meet the curing requirements. After the judgment is completed, it is sent to the early warning module, and the early warning module sends instructions to the steam delivery pipeline 2-1-1 through the information transmission module.

[0113] The data processing module is used to receive and analyze the data detected by the environmental temperature and humidity real-time monitoring device 1-4, convert the received data into a format readable by the controller, and process the converted data;

[0114] The logic judgment module is used to judge whether the current environment meets the maintenance requirements according to the preset temperature and humidity thresholds; the staff sets the temperature and humidity thresholds in the controller in advance, and the logic judgment module judges whether the indoor temperature is within the temperature and humidity thresholds. If it is, it will continue to process the next set of data, otherwise it will send instructions to the early warning module;

[0115] The early warning module is used to remind the staff that the real-time monitoring device 1-4 for environmental temperature and humidity detects that the temperature and humidity in the concrete mold 1 exceed the preset temperature and humidity thresholds, and synchronously controls the electric valve 2-1-2 of the steam delivery pipeline 2-1-1 to open and adjust the indoor temperature and humidity.

[0116] The information transmission module is used to transmit instructions and data.

[0117] Embodiment 8:

[0118] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 On the basis of Example 1, the position of the drainage channel 1-2 is defined, the drainage channel 1-2 is arranged at the bottom of the concrete mold 1, and the drainage channel 1-2 is fixed on both sides of the curing chamber 1-1.

[0119] The drainage channel 1-2 is located at the bottom of the concrete mold 1, which can ensure that the water accumulated inside the mold can be directly and quickly discharged through the drainage channel 1-2, avoiding the retention and accumulation of water inside the mold. By timely draining the water inside the mold, the humidity in the curing room 1-1 can be maintained relatively stable, avoiding the degradation of concrete quality due to excessively high or low humidity.

[0120] Embodiment 9:

[0121] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, on the basis of Example 1, the shape of the embedded pipe 1-1-2 is limited. Specifically, the embedded pipe 1-1-2 is cylindrical.

[0122] The cylindrical structure has excellent bearing capacity in mechanics. Since the circular cross-section has the largest area under the same circumference, the cylindrical embedded pipe 1-1-2 can better disperse and withstand the pressure from the large-volume concrete structure of the foundation, thereby improving its overall bearing capacity.

[0123] At the same time, when the cylindrical pre-buried pipe 1-1-2 is subjected to external force, the pressure on each surface is relatively uniform. In contrast, if the pre-buried pipe 1-1-2 adopts other shapes such as a quadrilateral, the structure may be damaged due to the pressure difference. Therefore, the cylindrical pre-buried pipe 1-1-2 with more advantages in force performance is selected.

[0124] Embodiment 10:

[0125] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and 7 As shown, based on Example 2, the environmental temperature and humidity real-time monitoring device 1-4 is in the hot steam environment inside the concrete mold 1 for a long time, and there is a risk of moisture, so the environmental temperature and humidity real-time monitoring device 1-41 needs to be protected.

[0126] Specifically, the environmental temperature and humidity real-time monitoring device 1-4 is provided with a moisture-proof layer; the moisture-proof layer is a sealant and a waterproof gasket.

[0127] Specifically, seal the interfaces, gaps and other water-permeable parts of the monitoring device, using sealants, waterproof gaskets and other materials to ensure that the internal circuits and sensors are not affected by moisture.

[0128] At the same time, the monitoring device should be checked regularly, and moisture and water droplets should be dealt with in time. Desiccant, moisture-absorbing bags and other materials can be placed near the monitoring device to absorb moisture in the air.

[0129] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.

[0130] Many other changes and modifications may be made without departing from the concept and scope of the present invention.It should be understood that the present invention is not limited to the specific embodiments, and the scope of the present invention is defined by the appended claims.
