[0036] The construction method of the intelligent water curing system for large-volume concrete includes the following steps:

[0037] S1: Construction preparation, preparing materials and arranging personnel division of labor;

[0038] S2: Spraying plane pipeline layout, the main water collection channel 8 is connected in parallel with each water collection channel 52 and then merged into the sedimentation tank 7; the sedimentation tank 7, the transition tank 6 and the maintenance water storage tank 4 are connected and then the main pipeline 41 is laid; the main pipeline 41 is connected to each primary pipeline 50, the primary pipeline 50 is connected to each secondary pipeline 51, and the secondary pipeline 51 is connected to the tertiary pipeline 53. Three-way valves are used at the connection points of the main pipeline 41, the primary pipeline 50, the secondary pipeline 51 and the tertiary pipeline 53; if the box beam 9 is located on the box beam pedestal 54, the tertiary pipeline 53 is connected to the top plate pipeline 531, the web pipeline 532, the beam end pipeline 533, the inner cavity pipeline 534 and the bottom plate pipeline 535; if the box beam 9 is located in the water curing tank 55, the tertiary pipeline 53 is connected to the top plate pipeline 531, the web pipeline 532, the beam end pipeline 533, the inner cavity pipeline 534 and the water curing tank 55; the secondary pipeline 51 of the beam making station 31 is connected to the primary pipeline 50 and is connected to the top plate pipeline 531, the beam end pipeline 533 and the inner cavity pipeline 534 through the tertiary pipeline 53;

[0039] S3: The spray device is installed. The outlet of the bottom plate pipe 535 is connected to the horizontal fan-shaped lateral nozzle 5351, the outlet of the web pipe 532 is connected to the web nozzle 5321, the outlet of the inner cavity pipe 534 is connected to the planetary nozzle 5341, and the outlet of the top plate pipe 531 is connected to the rotary nozzle 5311; the interval between adjacent horizontal fan-shaped lateral nozzles 5351 is 5 to 6 meters, the interval between adjacent web nozzles 5321 is 5 to 6 meters, the interval between adjacent planetary nozzles 5341 is 5 to 6 meters, and the interval between adjacent rotary nozzles 5311 is 5 to 6 meters;

[0040] S4: Control system installation, wiring between the main control console 1 and the beam storage control console 11 and the beam making control console 12, wiring between the beam storage control console 11 and the beam making control console 12 and the beam storage area 2 and the beam making area 3 respectively;

[0041] S5: Intelligent operation, the main control console 1 collects data from the temperature sensors 541 and the humidity sensors 542 in the beam storage area 2 and the beam manufacturing area 3 and gives maintenance instructions.

[0042] In order to reduce the waste of water resources, the construction of the water collection channel 52 is laid out using concrete and other impermeable materials, and the height difference is designed during the construction process to determine the direction of the water flow to the sedimentation tank 7. The sedimentation tank 7 can also be used as a device for collecting natural precipitation, which is more environmentally friendly. The beam field pipeline is relatively densely laid, and the pipeline needs to be pre-buried during the construction of the beam field to facilitate subsequent construction and reduce pipeline loss. The main pipeline 41 is laid with a durable PVC pipe with an inner diameter of 120mm. The primary pipeline 50, secondary pipeline 51, and tertiary pipeline 53 in the beam storage area 2 and the beam making area 3 are all hot-melt pipelines with an inner diameter of 60mm. Projects without winter construction can be laid out in the open, and projects under winter construction can adopt protective measures such as underground burial, heat preservation, and heating belts. The beam field has a wide maintenance area, and the top plate of the box beam 9 at the maintenance position is higher than the height of the maintenance reservoir 4, and large-scale spraying is required during the maintenance process. Considering the economy, a booster pump 40 is set to provide transportation power for the system water source. The pipe installation in beam making area 3 needs to be fixed to each other in combination with the beam making pedestal and the external formwork to ensure its stability. The spray device is the terminal component of the system and is also the most important structural component for completing the maintenance task. Therefore, different spray devices are also set up to deal with different maintenance positions. The spray device of the bottom plate is a horizontal fan-shaped horizontal nozzle 5351. The normal spraying range of the horizontal fan-shaped horizontal nozzle 5351 is about 10㎡. Generally, it is arranged at a distance of 5 to 6 meters to meet the maintenance of the bottom plate. The web spray device selects the web nozzle 5321. The web nozzle 5321 can spray a horizontal fan-shaped water mist surface, and this type of device is arranged on the branch line on the ground, and can also fill the maintenance water in the position that the bottom plate maintenance device cannot cover. The inner box spraying device adopts a planetary nozzle 5341, which is connected by the quick-release interface of the bottom pipe of the box beam 9. After the planetary nozzle 5341 is connected, it directly extends from the end of the box beam or the drain hole into the inner box of the box beam, and the excess maintenance water is collected from the drain hole to the sedimentation tank 7. The top plate spraying device selects a rotating nozzle 5311, which can be fixed (or rotated) at a fixed angle to disperse water mist in a fan shape. The spraying range of a single rotating nozzle 5311 can reach 10 to 15 square meters under full power. According to the design and layout of the corresponding number of nozzles in the top plate area of ​​the box beam, the maintenance effect can be achieved. The main control console 1 adopts the control concept of "smart +" site, and the control system adopts an overall intelligent integrated terminal control system. In order to cope with special situations, the beam field intelligence center adds independent manual (automatic) integrated control substations in each partition to meet various situations on the construction site. The system collects effective information from the construction site for intelligent analysis, and then issues scientific control instructions after calculation to achieve scientific, reasonable and economic management of beam field maintenance work. The digital system integration installation of the intelligent control system uses optical fiber network connection. Due to the large number of digital interface locations involved in the smart beam field, this networking method does not require separate wiring and supports multiple forms of connection, such as Ethernet, WIFI, 4 / 5G, etc.Users can directly access the "Smart+" system to improve management efficiency and intelligence. The beam storage console 11 and the beam making console 12 can independently control the start and stop of the maintenance equipment in this partition, and control the water volume and water pressure. At the same time, the console can choose automatic mode or manual mode. The manual control mode can deal with special situations such as network problems to ensure that on-site maintenance meets quality requirements. After the installation and networking of the water circulation system and the control system are completed, the debugging work is carried out to preliminarily debug the working conditions of the entire system to ensure that manual instructions and the smart integrated system can normally allocate the spraying device. Then the "Smart+" system programming work is carried out, that is, intelligently collect relevant data, integrate and analyze, and then issue instructions to scientifically regulate the work of the entire spraying system. After completing the basic integrated terminal control debugging of the equipment, programming can be based on the collection of various effective information, and data analysis can be carried out based on the basic information sources of region, time period, temperature, and humidity, and then scientific regulation can be carried out. The basic principle of humidity control operation is to collect the humidity conditions of the construction site, combine the evaporation, and use the "Smart+" cloud model for analysis to obtain the best maintenance time and time interval for each maintenance point on site. And during the change of seasons, humidity control is based on real-time environmental conditions, starting from the actual maintenance tasks at the construction site, and accurate calculations and scientific analysis are performed to ensure that each maintenance point achieves the best maintenance conditions.

[0043] This method combines the control terminal with intelligent construction, integrates intelligence into on-site construction, and lays a solid foundation for improving independent innovation capabilities. The spraying area, time period, and duration are set independently to avoid the occurrence of factors such as lack of responsibility of operators and human intervention, laying a solid foundation for ensuring the quality of beam concrete. The system is invested once and can be recycled. In addition to normal maintenance, no further investment is required; compared with the previous manual covering and watering maintenance, it can save millions of yuan in costs, and it is an important manifestation of refined management in grassroots projects. This method is suitable for construction projects in extreme weather areas such as high temperature, high cold, large temperature difference, and strong wind, especially for factory construction sites. It is particularly convenient. This intelligent spraying technology not only repeatedly and cyclically utilizes water resources, but also can reasonably recycle the spraying water, truly saving water resources and achieving environmental protection. In summary, this method is suitable for intelligent spraying maintenance construction of large-volume concrete such as prefabricated components that require water maintenance.
