First, the causes of road and bridge engineering quality problems.
Reasons for choosing 1 material. The most important thing for the quality of road and bridge construction is the choice of materials. Good materials make roads and bridges have long service life and high utilization rate. On the other hand, poor materials or non-conforming material ratio will affect the construction and even bury potential safety hazards.
2. Construction technical reasons. Technical problems in the construction process are also one of the important factors affecting the quality of road and bridge engineering. Pay more attention to the smoothness of pavement bridges, such as ignoring the compaction of asphalt pavement base because of the smoothness of pavement, or over-compacting at low temperature, resulting in uneven asphalt pavement. The level of construction technology directly affects the quality of engineering construction. In order to improve the quality of engineering construction, advanced and scientific construction technology must be fully applied.
3 reasons for construction management and personnel use. Construction management refers to the attention of leaders and the management measures introduced. Leaders have poor quality awareness, ignore construction procedures and violate rules and regulations; Improper management measures, imperfect supervision and other management reasons cause quality problems. At the same time, the quality problems of roads and bridges will also be caused by the operators, improper use of materials, irregular mechanical operation and inadequate construction at the construction site.
Second, measures to improve the quality of road and bridge engineering.
1 Prepare before construction. Before the formal construction, the construction unit shall conduct on-the-spot investigation of the project, analyze and record its geographical location, objective phenomena and climatic reasons, and make emergency preparations for possible emergencies. At the same time, we should pay attention to strengthening the configuration of machinery, maintaining the best combination of machinery and fully improving the utilization rate of machinery. Organize emergency repair and maintenance, fully prepare the key parts, ensure the quality on time, troubleshoot at any time and place, ensure the mechanical integrity rate and ensure the efficient and normal operation of the project.
2. Strengthen the management of road and bridge construction. Construction management is an important part of engineering construction quality management, and the quality of management affects the overall quality of the project. In order to ensure the engineering quality, construction management must be done well.
2. 1 material quality management. The selection and purchase of materials should be based on quality and must be purchased from regular manufacturers. When purchasing, manufacturers need to provide relevant quality certificates and technical certificates to meet the needs of construction and the regulations of relevant departments. The mixing and proportioning of materials must be carried out by construction personnel in strict accordance with the strength grade and impermeability grade. At the same time, it is necessary to do a good job in deep processing of some materials before use, such as effective vibrating of concrete before use.
2.2 Site management in construction. The use of mechanical equipment shall comply with the relevant regulations, and the management of bridge survey, structural setting, appearance beautification, construction process and technical application shall be strengthened, and it shall be implemented in accordance with the regulations. At the same time, do a good job in personnel deployment, leadership, guidance and supervision of the construction site.
2.3 Completion quality control management. The quality control management in the completion stage is to check and evaluate the strength, smoothness and bearing capacity of the pavement, and remedy, build or rebuild the existing problems in time. Ensure that roads and bridges do not collapse, crack, be uneven or sink, ensure the normal and safe operation of vehicles, and ensure that bridge accidents do not occur.
3. Strengthen the training of construction personnel. The quality of road and bridge engineering is the result of cooperation between managers and operators involved in engineering construction, and their professional quality directly affects the engineering quality. Therefore, it is necessary to train the construction personnel and constantly improve their comprehensive qualities such as quality awareness, technical quality and production capacity. Establish the concept of "quality first, prevention first, speaking with data, paying equal attention to social benefits and enterprise benefits". Managers and technicians need to have strong planning and management skills; As direct builders, production personnel should have superb technology and pragmatic style, strictly implement quality standards and operating procedures, and indirectly ensure the quality of road and bridge projects with excellent services.
Third, the conclusion
In recent years, with the continuous development of road and bridge engineering construction in China, various quality problems have emerged. The responsibility of road and bridge engineering construction quality is more important than Mount Tai, which must be attached great importance by relevant departments. To strengthen the quality management of road and bridge engineering and ensure the engineering quality, we must strengthen the basic work, construction quality control and inspection. In the future road and bridge construction, we should pay more attention to all kinds of hidden dangers, constantly explore and innovate, constantly strengthen the quality management of road and bridge engineering, improve the quality level of road and bridge engineering construction, ensure the stability and safety of bridge use, further improve the service quality and service life of bridges, and push China's road and bridge engineering construction to a higher development stage.
