PDCA Cycle Method for Construction Quality Management and Control of Small and Medium-Sized Hydraulic Engineering

Overall, the PDCA cycle method is a continuous improvement process that involves planning, doing, checking and acting. In the pre-construction stage, the quality control system involves project planning, site selection, design review and procurement of materials. During the mid-construction stage, the quality control system involves construction supervision, quality inspection, safety management and progress monitoring. In the post-construction stage, the quality control system involves acceptance inspection, defect rectification and maintenance.

The quality control system is applied to the actual project by establishing a quality control team, which is responsible for implementing the quality control system and conducting regular inspections. The team is composed of professionals with relevant expertise, including engineers, surveyors, inspectors and safety supervisors. They work together to identify potential risks and hazards, and develop measures to prevent them from occurring.

Finally, the quality grade is evaluated by engineering acceptance, which involves a comprehensive review of the project's design, construction process, quality control measures and final outcomes. The acceptance criteria are based on national standards and regulations, as well as the specific requirements of the project. The evaluation process is conducted by a third-party organization to ensure objectivity and fairness.

In conclusion, the construction quality management and control system based on PDCA cycle method is an effective way to ensure the quality and safety of small and medium-sized hydraulic engineering projects. It provides a structured approach to quality control that can be applied throughout the project lifecycle, from planning to acceptance. By implementing this system, we can improve the overall quality of water conservancy and hydropower projects, and contribute to the sustainable development of our economy and society.
