Although the existing underwater non-dispersible concrete has solved the problem of concrete dispersion underwater to a certain extent, it still has some shortcomings. For example, the performance of anti-dispersants needs to be further improved to adapt to more complex underwater environments; the quality control of concrete during construction is not accurate enough, and quality problems are prone to occur; the post-maintenance and quality inspection methods are not perfect, and it is difficult to ensure the long-term performance of concrete.

Even in a complex underwater environment with high water flow and high water pressure, the concrete can maintain good stability and strength. The anti-dispersion agent is composed of a polymer flocculant, bentonite, a water-retaining agent and a water-reducing agent.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the embodiments of the present invention are specifically cited below and described in detail with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required for use in the embodiments are briefly introduced below. It should be understood that the following drawings only show certain embodiments of the present invention and therefore should not be regarded as limiting the scope. For ordinary technicians in this field, other related drawings can be obtained based on these drawings without creative work.

[0029] Figure 1It is a flow chart of the underwater non-dispersible concrete panel construction method described in the embodiment. DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0031] Please refer to Figure 1 The embodiment of the present invention provides an underwater non-dispersible concrete panel construction method, comprising the following steps:

[0032] 1. Construction preparation:

[0033] 1) Material preparation

[0034] Material preparation involves the preparation of a new type of anti-dispersant, which consists of a polymer flocculant, bentonite, a water retaining agent and a water reducing agent.

[0035] Material preparation in construction preparation also includes quality testing of concrete raw materials, specifically testing cement strength grade, fineness, setting time and other indicators to ensure that cement quality meets national standards; testing aggregate particle grading, mud content, mud block content and other indicators to ensure the cleanliness and grade matching rationality of aggregate; testing water quality to ensure that the water does not contain harmful substances that affect the performance of concrete, thereby ensuring the stable and reliable performance of concrete and laying a good foundation for subsequent construction. As the main cementitious material of concrete, cement's strength grade, fineness, setting time and other indicators directly affect the strength development and durability of concrete. Through testing, cement that meets national standards can be screened out to provide good cementing properties for concrete. Aggregate particle grading, mud content, mud block content and other indicators are related to the workability and density of concrete. Aggregates that pass the test can ensure that concrete has good fluidity and filling properties during mixing and pouring, reduce porosity, and improve the strength and durability of concrete. Water quality testing ensures that the water does not contain harmful substances that affect the performance of concrete, avoiding the degradation of concrete performance due to water quality problems. This series of testing measures controls the quality of concrete raw materials from the source, laying a solid foundation for subsequent construction, effectively avoiding unstable concrete performance due to raw material quality problems, reducing the risk of rework and maintenance of the project, and improving the overall quality and service life of the project.

[0036] 2) Equipment preparation

[0037] The prepared equipment includes intelligent pouring equipment, intelligent mixing equipment, intelligent transport vehicles, modular formwork, underwater robots and intelligent maintenance equipment.

[0038] This embodiment also debugs and calibrates the intelligent equipment, specifically calibrating the flow sensor and pressure sensor of the intelligent pouring equipment to ensure that their measurement accuracy meets the construction requirements; debugging the control system of the intelligent mixing equipment to ensure that it can accurately add materials according to the preset ratio; testing the GPS positioning system and wireless communication module of the intelligent transport vehicle to ensure that it can stably transmit concrete status information; debugging the operating performance of the underwater robot to ensure that it can accurately fix the modular template; calibrating the control system of the intelligent maintenance equipment to ensure that it can accurately control the maintenance environment parameters, thereby ensuring the stable operation and precise control of the equipment during the construction process. These debugging and calibration measures effectively improve the reliability and accuracy of the equipment during the construction process, reduce the construction quality problems caused by equipment failure or inaccurate control, improve the construction efficiency and the performance stability of the concrete, and ensure the overall quality and progress of the project.

[0039] 2. Base surface treatment

[0040] Use a high-pressure water gun to clean the base surface to ensure that it is free of debris and oil stains, and use underwater video equipment to check the flatness and solidity of the base surface to ensure that the base surface meets the construction requirements.

[0041] This embodiment also measures the dimensional deviation of the base surface, specifically, using underwater measuring instruments to accurately measure the length, width, thickness and other dimensions of the base surface, and compare them with the design requirements to ensure that the dimensional deviation of the base surface is within the allowable range; if the dimensional deviation of the base surface exceeds the allowable range, it is trimmed manually or mechanically until the base surface size meets the construction requirements, thereby ensuring the installation accuracy of the concrete panel and the stability of the overall structure. This process effectively avoids the problems of uneven and loose installation of concrete panels caused by the dimensional deviation of the base surface, ensures good connection between concrete panels, and improves the integrity and stability of the structure. At the same time, accurate base surface dimensions also provide a reliable benchmark for subsequent construction, which is conducive to improving construction accuracy and efficiency. In addition, precise control of the base surface dimensions also helps to reduce the waste of concrete and reduce engineering costs. In short, the measurement and trimming of the base surface dimensional deviation controls the quality of the project in detail and provides a strong guarantee for the smooth construction of underwater non-dispersed concrete panels.

[0042] 3. Preparation and addition of anti-dispersant

[0043] The proportion of anti-dispersant is adjusted according to the specific conditions of the underwater environment, and the anti-dispersant is accurately added during the concrete mixing process through the control system of the intelligent pouring equipment.

[0044] This embodiment also takes into account factors such as underwater temperature and salinity. Specifically, in a low temperature environment, the amount of water retaining agent is appropriately increased to improve the water retention performance of concrete, prevent the concrete from losing water too quickly due to low temperature in the underwater environment, and ensure the workability and strength development of concrete; in a high salinity environment, the amount of bentonite is appropriately increased to enhance the concrete's resistance to salt erosion, prevent the concrete from experiencing performance degradation due to salt erosion, and thus ensure the non-dispersibility and durability of concrete under different underwater environmental conditions. This targeted ratio adjustment enables the anti-dispersant to better adapt to different underwater environments and give full play to its anti-dispersion effect. At the same time, a reasonable ratio also helps to improve the economy of concrete and avoid the cost increase caused by excessive use of anti-dispersant. In addition, the optimized anti-dispersant can also improve the workability of concrete, so that it has better fluidity and filling properties during underwater pouring, and improves the construction quality. In short, adjusting the anti-dispersant ratio according to the underwater environment effectively improves the performance of concrete in a complex underwater environment, and provides a reliable guarantee for the construction of underwater non-dispersible concrete panels.

[0045] 4. Mixing and transportation of concrete

[0046] Use intelligent mixing equipment to automatically add materials according to the preset ratio and monitor the mixing status in real time. Then use the GPS positioning system and wireless communication module equipped in the intelligent transport vehicle to monitor the status of concrete during transportation in real time.

[0047] This embodiment also monitors the slump, air content and other performance indicators of concrete in real time. Specifically, during the mixing process, the built-in sensor of the intelligent mixing equipment collects the slump, air content and other data of the concrete in real time, and compares them with the preset performance indicator range; if the slump or air content of the concrete exceeds the preset range, the amount of material added or the mixing time is automatically adjusted until the performance indicators of the concrete meet the construction requirements, thereby ensuring the stable and reliable quality of the concrete and providing guarantees for subsequent pouring and molding. This process effectively avoids the problem of unstable concrete performance caused by uneven mixing or improper material ratio, and ensures the good workability of concrete during transportation and pouring. At the same time, real-time monitoring and automatic adjustment can also improve mixing efficiency, reduce manual intervention, and reduce labor intensity. In addition, stable concrete performance helps to improve construction quality, reduce engineering defects, and extend the service life of the project. In short, real-time monitoring and automatic adjustment of concrete performance indicators provide high-quality concrete materials for underwater non-dispersed concrete panel construction, ensuring the overall quality and progress of the project.

[0048] 5. Installation of modular formwork

[0049] Modular templates made of high-strength plastic are used, and the templates are fixed by underwater robots to ensure the stability and accuracy of the templates.

[0050] This embodiment also detects the installation accuracy of the template. Specifically, after the template is installed, underwater measuring instruments are used to detect the installation accuracy indicators such as the position, flatness, and verticality of the template; if the installation accuracy of the template does not meet the requirements, the underwater robot is used to make fine adjustments until the installation accuracy of the template meets the construction requirements, thereby ensuring the molding quality and structural stability of the concrete panel. This embodiment effectively avoids the problems of dimensional deviation and surface unevenness of the concrete panel caused by inaccurate template installation, and improves the molding quality of the concrete panel. At the same time, accurate template installation also helps to improve construction efficiency and reduce construction delays caused by template adjustment. In addition, the improvement of template installation accuracy is also conducive to enhancing the bonding force between the concrete panel and the base surface, and improving the overall stability of the structure. In short, the use of underwater robots to fix the template and detect the installation accuracy provides reliable template support for the construction of underwater non-dispersed concrete panels, ensuring the quality and safety of the project.

[0051] 6. Concrete pouring

[0052] The intelligent pouring equipment receives control instructions through the wireless communication module to accurately control the pouring speed and amount of concrete, and uses an underwater vibrator controlled by the intelligent pouring equipment control system to automatically adjust the vibration frequency and vibration time.

[0053] This embodiment also makes adjustments according to the pouring thickness and pouring speed of the concrete. Specifically, when the pouring thickness is large, the vibration frequency and vibration time are appropriately increased to ensure that the bubbles inside the concrete are fully discharged to avoid quality problems such as honeycomb surface; when the pouring speed is fast, the vibration frequency is appropriately increased to ensure the density of the concrete, thereby ensuring the pouring quality of the concrete panel. This process effectively avoids concrete quality problems caused by insufficient or excessive vibration, and improves the pouring quality of concrete. At the same time, automatic adjustment of vibration parameters can also improve construction efficiency, reduce manual intervention, and reduce labor intensity. In addition, good concrete pouring quality helps to improve the overall performance and durability of the project. In short, automatically adjusting the vibration parameters according to the pouring thickness and speed provides a high-quality concrete pouring process for the construction of underwater non-dispersed concrete panels, ensuring the overall quality of the project.

[0054] 7. Post-maintenance and quality inspection

[0055] Intelligent maintenance equipment is used to automatically control the maintenance environment according to preset maintenance parameters, and underwater video equipment and non-destructive testing equipment are used to monitor and evaluate the quality of concrete in real time.

[0056] This embodiment also monitors the temperature, humidity, chloride ion content and other maintenance environment parameters of concrete in real time. Specifically, during the maintenance process, the temperature, humidity, chloride ion content and other data of concrete are collected in real time through the built-in sensors of the intelligent maintenance equipment, and compared with the preset maintenance parameter range; if the maintenance environment parameters exceed the preset range, the operating parameters of the maintenance equipment, such as heating power, humidification amount, etc., are automatically adjusted until the maintenance environment parameters meet the requirements, thereby ensuring the maintenance quality of the concrete. This process effectively avoids the problem of concrete performance degradation caused by improper maintenance environment and ensures the strength and durability of concrete. At the same time, automatic control of the maintenance environment can also improve maintenance efficiency, reduce manual intervention, and reduce labor intensity. In addition, good maintenance conditions help reduce shrinkage and cracks in concrete and improve the overall quality of the project. In short, the use of intelligent maintenance equipment to automatically control the maintenance environment provides reliable post-maintenance guarantees for underwater non-dispersed concrete panel construction and extends the service life of the project.

[0057] This embodiment also detects the internal defects of concrete, specifically using ultrasonic detection equipment to scan the inside of the concrete to detect whether there are defects such as cracks and cavities inside the concrete; if defects are found inside the concrete, the location and range of the defects are further observed by underwater camera equipment, and corresponding repair measures are taken according to the defects, so as to ensure the overall quality and structural safety of the concrete panel. This embodiment effectively avoids the structural safety hazards caused by concrete quality defects and improves the overall quality and reliability of the concrete panel. At the same time, real-time monitoring and evaluation can also timely discover changes in concrete performance, providing a basis for subsequent maintenance and repair. In addition, the detection and repair of internal defects helps to extend the service life of the project and reduce maintenance costs. In short, the monitoring and evaluation of concrete quality by underwater camera equipment and non-destructive testing equipment provides comprehensive quality assurance for the construction of underwater non-dispersed concrete panels, ensuring the safety and stability of the project.
