At present, China's social and economic level continues to develop, and the population of the whole country is also rising, which makes the historical mission of China's water conservancy projects more and more important. In the process of China's national economic development and basic industry construction, water conservancy has always occupied a very important position. In the construction of water conservancy projects, the construction quality must be strictly guaranteed. Only in the spirit of continuous exploration and innovation can the quality of water conservancy projects be improved, and then the rational development and sustainable utilization of water resources can be guaranteed, so as to ensure social and economic development and promote social development. Therefore, based on years of practical experience, this paper analyzes the factors that may affect the quality of water conservancy project construction, and then constructs a more scientific and complete investment and construction management system, and implements a series of reform measures for water conservancy project infrastructure construction.

In the process of water conservancy project construction, there are many construction sites, wide engineering scope, large engineering quantity and high work difficulty. Therefore, quality accidents occur from time to time in the construction of water conservancy projects, and major and extraordinarily serious accidents often occur in the construction of water conservancy projects in more serious places, which have brought considerable loss of life and property to the people and the country. We need to attach great importance to these problems and further strengthen the supervision and management of the quality and safety of engineering construction.

1, quality problems that often occur in water conservancy project construction

The cost of 1. 1 is insufficient.

At present, many small and medium-sized water conservancy projects have little investment, and most of the construction funds are raised by local governments, which often leads to insufficient funds, resulting in outdated water conservancy project construction and experimental equipment, lack of necessary and powerful professional testing means, and can only be judged by personal experience.

1.2 subcontracting and invisible subcontracting occur in many water conservancy projects.

In the process of water conservancy project construction, the subcontracting of the main project is strictly managed, and it is expressly stipulated that subcontracting and subcontracting are not allowed in the construction process. However, in the actual construction process of water conservancy projects, the main projects of small and medium-sized water conservancy projects are often subcontracted layer by layer, and most of the subcontractors involved in subcontracting have not passed the strict professional construction qualification examination. The complicated leadership relationship has seriously hindered the implementation of various quality management measures of supervision engineers, making it impossible for supervision engineers of water conservancy projects to play their due role in front-line working faces.

1.3 Many water conservancy projects are in a hurry to catch up with the progress and grab the construction period.

In the process of water conservancy project construction, there is often a situation of rushing for progress and time limit for a project, so many processes are ignored and most of them are perfunctory. For example, in the process of construction, the layer and wound are not cleaned thoroughly, the galling degree can not meet the relevant construction standards, and the joint surface of new and old concrete is not paved with mortar as required, or only a little. In order to reduce the trouble, there is no keyway on the horizontal construction joint surface of concrete in water conservancy projects, which leads to grouting or water storage along the construction joint surface in water conservancy projects.

2. Problems and countermeasures in the construction of water conservancy projects.

2. 1 Establish and improve the quality management system

By strengthening the legal consciousness of water conservancy project construction and management personnel, strengthening the construction of relevant legal system, conscientiously implementing and abiding by relevant laws and regulations, helping construction and management personnel to improve their consciousness of handling affairs according to law. In the construction of water conservancy projects, only by establishing and improving the quality management system of water conservancy projects can the quality of water conservancy projects be guaranteed. With the help of a perfect construction quality management system, the responsibilities of various departments in engineering construction can be clarified, the quality monitoring system can be improved, and the quality control in construction can be guaranteed. In addition, ensure that the main project is not subcontracted or subcontracted, and conduct pre-research on the whole project to find out possible problems and focus on monitoring to avoid quality problems in construction.

2.2 Responsibility for individuals

The quality of water conservancy projects is closely related to the attention of leaders. Therefore, the water conservancy department needs to pay close attention to the quality of water conservancy projects, be truly responsible to the people, be responsible for history, implement the responsibility to individuals, and strengthen supervision and inspection at all levels. Carry out the lifelong system of engineering quality, so that engineers can be really serious and responsible.

2.3 Pay attention to the quality control of materials and equipment.

Before all kinds of building materials are transported to the construction site, it is necessary to provide the project supervision agency with the building material inspection form, and also attach the product factory certificate and technical specifications, and then the construction contractor can carry out inspection or test according to the specified requirements, and can only enter the site after being determined by the supervision engineer to be qualified. For those building materials that are prone to quality loss due to the environment and climate, strict control is needed. It is also necessary to regularly check and maintain all kinds of equipment to ensure that it is in the best working condition, and the supervision engineer is responsible for all inspections.

3. Strict technical management

Technical management includes technical responsibility system, construction diary, blue prints.the design, technical disclosure, technical review, material inspection, technical archives, project acceptance and other systems. Therefore, it is necessary to clarify the responsibilities and authority of each engineering and technical personnel; In the process of construction, the person in charge of construction technology should carefully keep a construction diary on time, and record the daily construction situation, problems and solutions in detail, so as to provide a basis for future completion acceptance and quality evaluation; Pay attention to the joint review of drawings, correct the mistakes as soon as possible, and record the mistakes in order to eliminate them; Let every professional technician and worker involved in the construction know the characteristics, technical requirements and construction technology of the project under construction; Arrange special personnel to review all technical work, correct mistakes in time, and avoid man-made engineering quality accidents; During the construction process, attention should be paid to sampling inspection of all materials used to ensure that they meet the design requirements before use.

4. Pay attention to the professional quality of on-site technicians.

The quality of the project directly depends on the professional quality of the construction personnel. Through the professional technical training for construction personnel and operators, the professional quality level of technicians can be significantly improved, and the operation level of operators can also be improved, so as to better improve the construction quality of water conservancy projects. Therefore, in the process of recruiting technicians, engineering construction enterprises need to pay attention to the professional technical level and personal quality level of operators and technicians. In the process of construction, attention should be paid to the on-the-job training of technicians. With the help of regular engineering training, the personal technical level of construction personnel can be improved, and the construction safety awareness of water conservancy project construction personnel can also be significantly improved, thus promoting the safety management of water conservancy project construction and reducing the probability of engineering accidents.

5. Conclusion

The construction of water conservancy projects is directly related to the construction of people's livelihood and occupies an important position in building a harmonious socialist society. All parties should attach great importance to it, realize the healthy, smooth and sustainable development of water conservancy projects, and provide a strong guarantee for people's happiness, national prosperity, social stability and economic development.
