In recent years, with the continuous acceleration of China's modernization process, the scale and technical level of electrical engineers have been greatly improved. At the same time, the construction quality of electrical engineering has also become the focus of attention. As the main link in electrical engineering, electrical engineering installation must form a good cooperative relationship with construction in order to achieve the expected effect. Only systematic installation procedures and accurate implementation techniques can effectively implement and manage the installation links of electrical engineering, thus laying a more solid foundation for the smooth development of the whole electrical engineering.

1 Importance of coordination in installation and construction of electrical engineering

Electrical engineering installation is an indispensable part in the process of electrical engineering implementation, which is mainly divided into four basic construction stages, namely, construction preparation stage, foundation preparation stage, wall structure stage and interior decoration stage. There is a close relationship between all aspects of electrical engineering installation, especially the cooperation with other majors, which will play a decisive role in the effectiveness and accuracy of electrical engineering installation. In particular, it has the closest relationship with civil buildings. If the electrical engineering link is not fully coordinated with the civil construction, only considering the work situation of this major will not only have a great impact on the installation effect of electrical engineering, but also hinder the development of other professional work and even make the project suffer certain losses and economic losses in the case of coordination problems. Therefore, it is particularly important to coordinate the installation and construction of electrical engineering.

2 the embodiment of electrical engineering installation and construction cooperation

For the whole construction project, the installation of electrical engineering runs through it all the time, which means that the installation of electrical engineering is an important part of the construction project. Therefore, in the implementation process of electrical engineering installation, technicians will strictly limit the operation and adjustment at each stage to ensure the comprehensiveness and effectiveness of the implementation of the main work of the project. In order to attract technicians' attention to the coordination of electrical engineering installation and construction, the coordination of each link of electrical engineering installation and construction is summarized in combination with years of work experience.

2. 1 Coordination between preparation stage and construction

Under normal circumstances, before the implementation of construction projects, it is necessary to make preparations for various projects. For electrical engineering, electrical design should be carried out first. At this time, it is necessary to cooperate with the civil design link. For example, in the embedded work of switch cabinet foundation steel, in order to ensure the accuracy of embedded electrical equipment and lines, before construction, electrical installers should review and discuss the design and construction drawings of both parties together with civil technicians. And electrical installation technicians should know and understand the relevant links of civil engineering, including civil engineering construction methods and construction progress. , especially in the beam, column, floor and other important civil construction parts, we should be familiar with and master the connection methods and construction methods of these parts, so that the electrical installation project can be carried out more reasonably. At the same time, electrical installation technicians should systematically check whether each link of electrical installation engineering is different from civil engineering according to their own conditions, so as to be able to

2.2 Cooperation between foundation stage and construction

In building engineering, foundation engineering is the core link of building engineering implementation. Only by doing the basic work of building engineering well can we better manage and control the quality problems of building engineering. Therefore, technical personnel attach great importance to the cooperation between electrical installation engineering and construction in foundation engineering. Through understanding, in the implementation of building engineering foundation project, the cooperation between electrical installation and civil construction is mainly reflected in the following aspects: First, during construction, most of the pre-embedding work of electrical specialty should be carried out in consultation with civil construction, mainly including water stop plate, household cable through-wall pipe, protective pipe and so on. Especially when the electrical specialty is preparing for the ground waterproofing, it should arrange and deal with the details of the embedded work according to the design drawings. Here mainly refers to the reserved hole size, material specifications, etc. , can greatly improve the anti-leakage effect of waterproof floor. In addition, the excavation of holes is generally carried out by civil technicians, and the hole size is 300 mm, which is more suitable. Secondly, in the process of construction, in order to ensure the quality of wiring work in the bottom plate and foundation, electrical installation technicians should contact civil engineering technicians at any time, and from the perspective of civil engineering construction progress, timely put forward the situation that civil engineering personnel do not conform to the reserved holes in the drawings, and cooperate with civil engineering personnel to solve the problems in time so as not to delay the implementation of the next electrical installation work; Finally, in order not to affect the development of civil construction process, the problem of embedded parts in electrical installation specialty should also attract the attention of technicians. Common embedded parts include anchor bolts, wooden bricks, steel, iron pieces, elevators, etc. When dealing with embedded parts, electrical construction personnel should take civil construction technology as the standard. Once the work of civil construction personnel is implemented, electrical installation personnel should immediately embed embedded parts. At the same time, the grounding operation of foundation slab should also be based on design drawings, and electrical connection is the theoretical basis. When connecting the main reinforcement of foundation, the welding position should start from the root of the main reinforcement in the selected column, and between the bottom reinforcement, the welding position should also be marked, and test points for measuring grounding resistance should be reserved.

2.3 Decoration stage and construction cooperation

Indoor and outdoor decoration stage is the last processing link of construction project, which determines the beauty and comfort of the house. Of course, electrical installation works are also indispensable. At this stage, the cooperation between electrical installation project and civil construction is mainly designed as follows: 1. In order to accurately determine the elevation and position of pipes, lamps and switches, electrical specialty must take the horizontal line and separation line on the wall as the benchmark, and the marking work needs to establish partition connection in civil construction, which requires electrical installation technology. Secondly, the accurate determination of reserved holes is closely related to the installation of the box. In order to avoid the trouble caused by reserved holes, electrical installation technicians should verify the reserved holes before plastering, and check them in strict accordance with design drawings and specifications. The basic process of inspection is to check whether all concealed pipelines are in good condition, then sort out the pipelines, then thread them, and finally make a protective box. Only after the inspection process meets the requirements can the box be inspected. Thirdly, the process of sealing boxes and distribution boxes by pasting the front of the volume also needs the cooperation of electrical and civil engineering majors. Civil technicians are mainly responsible for the closing of plastering boxes. The operation standard is to ensure uniform plastering and smooth surface, and to prevent excessive folding. If the electrical installation technician takes over or connects the box between the wall and the insulation board, the civil engineer needs to open the wall and the insulation board. The size of the opening should be moderate, and the horizontal distance should be close to the groove. The electrical installation technicians are mainly responsible for the lightning protection and grounding connection of relevant parts of the building, and the key parts are metal doors and windows, aluminum frames of glass curtain walls, etc. Fourth, the installation of general lighting appliances should be carried out after the civil engineering technicians spray and plaster the indoor and outdoor walls. In the process of lighting installation, electrical installation technicians should always keep the wall clean and cherish the labor achievements of civil engineering technicians. After the installation of electric lamps is completed, secondary spraying should be carried out. Civil engineering technicians should pay attention to fill in the missing parts of the wall, and at the same time protect the electrical appliances during operation to avoid pollution or damage to the electrical appliances.

3 Conclusion

Practice shows that the coordination between construction methods and working procedures is a very important link in building electrical installation construction, which requires electrical construction personnel to have rich practical experience and in-depth understanding of the whole project. At the same time, we should have a high sense of responsibility and glorious mission in our work. In this way, we can not only do our professional work well, but also build the whole project well.
