1 preface
Electrical engineering construction is not only complicated, but also includes materials, line laying, electrical equipment and many other aspects. Compared with other projects, electrical engineering is more difficult. In the process of electrical construction, construction safety and quality management are of great significance to electrical engineering, which not only affects the safety and reliability of the whole project, but also affects the continuity and integrity of construction. Relevant personnel should strengthen the research on electrical engineering construction to ensure the quality of electrical engineering. However, there are still some problems to be solved urgently in electrical engineering in China.
2 electrical engineering quality control related concepts
The so-called quality control is a part of quality management, and its main purpose is to meet the quality requirements of customers or relevant laws. The construction process is the process that the project is transformed from the design on the drawing to the physical object, and this process is also the decisive stage of the whole project quality, so the quality control of electrical engineering construction is an important link of the project quality control. The construction of electrical engineering is completed by many links, so the quality control of electrical engineering is not only a whole and all-round systematic process from raw material quality control to project completion quality acceptance, but also a systematic control process from process quality to sub-project quality and then to sub-project quality control.
3 some problems of electrical engineering construction management and quality control
3. 1 Insufficient understanding of the role of electrical engineering in engineering projects.
Engineering construction is composed of many projects, and electrical engineering construction is only one of them. The construction units of some projects do not pay enough attention to the quality control of electrical engineering construction, and the quality requirements of electrical engineering construction are not strict, and there is a lack of corresponding quality monitoring system for electrical engineering construction. Therefore, the phenomenon of cutting corners often occurs in the construction process, which has great security risks. Not only did the construction unit fail to realize the importance of electrical engineering construction quality control, but also the construction unit did not pay enough attention to the importance of electrical engineering installation. Usually, the electrical engineering construction of the construction unit will be carried out as required, but the influence of electrical engineering construction on the whole project is often ignored.
3.2 Electrical engineering construction and other professional coordination is not in place.
In the whole construction process, the construction of electrical engineering does not exist in isolation. The professional coordination of other personnel (such as civil construction personnel) is needed to complete the electrical engineering construction with good quality and quantity. For example, without the on-site guidance and supervision of electrical construction technicians on concrete pouring and various pipeline embedment, electrical construction will not be carried out smoothly. However, in the actual electrical construction process, the coordination of various professionals is extremely uncoordinated, which brings great inconvenience to the electrical engineering construction, and even the electrical engineering cannot be carried out smoothly.
3.3 Electrical engineering construction personnel's professionalism is not high.
Electrical construction personnel need to undergo professional training and have strong professionalism and sense of responsibility. The quality of construction personnel has an important impact on the quality of electrical engineering construction. However, in some engineering projects, the construction personnel of electrical engineering are not familiar with the laws and regulations related to electrical construction, and even do not review the drawings and technical documents related to electrical construction. Most of them do not follow the normal construction procedures, and some irreversible situations may occur in the process of electrical engineering construction.
3.4 The supervision of electrical engineering construction quality is not enough.
In the process of electrical construction, it is also necessary to do a good job in the supervision of electrical engineering and establish a systematic and perfect supervision system to ensure the construction quality of the whole construction process. In the process of electrical construction, the thread ends, the depth of embedded pipes, the materials entering the switch and the rear socket box shall be inspected to ensure that the quality requirements are met. However, some engineering projects did not realize the importance of supervision and did not arrange special personnel to carry out supervision work, which led to some construction personnel taking advantage of loopholes and cutting corners, greatly reducing the construction quality of electrical engineering.
4 Effective measures for electrical engineering construction management and quality control
4. 1 Construction management and quality control in construction preparation stage
Division of labor and cooperation, clear responsibilities. When the electrical engineering has not yet started, the construction unit shall be responsible for the prevention and control of common quality defects, focusing on the key links that are prone to common quality defects in the construction of buildings, electrical installation and debugging, and line engineering; The design unit is responsible for the implementation and enforcement of mandatory provisions in the process of engineering construction; The construction unit is responsible for the implementation of standardized construction technology; The supervision unit is responsible for the whole process management of engineering construction, especially the management of common quality defects, the implementation of mandatory provisions and the standardized construction technology in construction. Set up on-site display boards for standard processes and common quality defects. The electrical engineer of the construction party and the technical personnel of electrical installation should be familiar with the design requirements of electrical construction drawings, which requires the electrical engineer to read and study the construction drawings in detail first, understand the design intent of the construction drawings, and ask the relevant personnel in time for those who don't understand.
4.2 Construction management and quality control in the construction stage
The construction of electrical engineering is a long process from project commencement to project completion. On-site supervision electrical engineers should give full play to the role, do a good job in the quality supervision of the whole process of electrical construction, and ensure that all links of construction meet the quality requirements. The construction unit shall carry out the construction in strict accordance with the standardized operating procedures, and the quality control program shall be standardized, up to standard and operable. Each working procedure must be signed by relevant personnel before the next working procedure can be started, and daily construction records should be kept for future investigation.
During the construction process, the construction unit shall prepare work instructions for different sub-projects and review them at the same time as the construction drawing disclosure. No construction shall be carried out without examination. Implement strong measures before construction, and organize construction personnel to watch standard construction technology demonstration discs; Set up quality and safety exhibition boards at the construction site, and carry out construction in strict accordance with standard construction procedures.
In the construction stage, the quality of materials should be strictly controlled and the quality control card system should be implemented. Materials must have factory certificate, qualified inspection report and retest report, and be signed by the construction unit and supervision unit to prevent the use of unqualified materials. There are many details in the quality control in the construction stage of electrical engineering, especially in the foundation construction stage. In the foundation engineering construction, the electrical construction unit should cooperate with the civil engineering unit to do a good job of pre-embedding and reserving the wall-penetrating pipe and water stop baffle of strong and weak household cables. This work should be completed before the waterproof treatment of the wall, so as to avoid water leakage of the wall caused by electrical construction. In the installation process of electrical construction, electrical construction personnel should keep learning and constantly improve their professional quality and technical level, so as to continuously improve the construction quality of electrical engineering in the construction process.
5 conclusion
In a word, in the quality management of electrical construction, the design scheme should be defined first. Quality management mainly includes improving production quality, implementing transformation, modification, control, testing and control, establishing and improving quality management system and strengthening quality monitoring of managers, which plays a vital role in ensuring the smooth progress of power construction projects. However, there are still many deficiencies in quality management in China at present. Most management departments ignore the electrical quality and do not strictly follow the relevant regulations when selecting materials, resulting in poor material quality, affecting the whole construction quality and hindering the construction process.
