With the rapid development of China’s construction, in order to strengthen the construction management of mechanical and electrical engineering, ensure the engineering quality and construction safety, it is imperative to improve the quality of mechanical and electrical engineering professional and technical personnel, and standardize the construction management behavior. With the advent of the electronic age, the traditional manual industry is gradually replaced, and electromechanical equipment is widely used in highway engineering. Therefore, the number of mechanical and electrical equipment installation is increasing rapidly, which inevitably leads to some problems in the installation process. These problems seriously affect the quality and safety performance of mechanical and electrical equipment, so we should understand the installation process and precautions of mechanical and electrical equipment, and clarify the structure and installation sequence of mechanical and electrical equipment. The level of mechanical and electrical engineering construction technology determines the construction progress, quality, safety and economy of the project, directly affects the benefit of the construction enterprise, and determines the sustainable development ability and competitiveness of the enterprise. The construction technology level of the enterprise is composed of the basic quality and technical level of several project leaders, constructors and all construction personnel.
This paper mainly describes the construction of mechanical and electrical installation of common quality problems and its prevention and control measures. In the mechanical and electrical installation construction work, including a variety of engineering projects, including drainage engineering, weak current engineering and electrical engineering, as well as fire engineering and air conditioning and ventilation engineering. The important part of mechanical and electrical installation engineering is electrical engineering and weak current engineering. Therefore, the material quality should be controlled, the installation technology level should be improved, and the construction management should be strengthened. Due to the lack of experience of the editor, there may be mistakes and omissions in the article. Readers are welcome give criticism and correction.
