The following aspects should be noted for electromechanical installation safety:
Cross-operation issues are common in construction projects,Electromechanical installationDuring construction, overlapping operations are often involved, mainly referring to the intersection of construction and decoration work. If overlapping tasks are not properly handled during construction, it can easily cause ineffective execution of pre- and post-construction processes, significantly impacting progress and efficiency. In such cases, it is necessary to negotiate and communicate with the owner, contractors, and civil engineers, strengthen cooperation, and adjust the process appropriately to avoid delaying construction progress.
In electromechanical installation projects, the issue of dark cloth conduits being pulled up and down from the floor is often involved. Therefore, during wall construction, it is necessary to carefully review the construction drawings, accurately locate the terminal junction box, and implement standardized construction operations according to the relevant construction documents and the owner's requirements.
3. In electrical conduit management, there are many and long electrical pipelines. Therefore, during installation, the pipelines must be neatly planned, checking the stability and leg of the pipelines. Special attention should be paid to the length of the pipelines, whether the cable bending radius meets relevant standards, whether the markings are smooth and bell-shaped, and sealing protection must be maintained at the end of cable operation.
4. Large Project Volume and Wide Fitting Scope Building projects are characterized by complexity and systematic nature. In a single project, civil engineering, decoration, and electromechanical construction often occur simultaneously. At this time, electromechanical installation projects need to be coordinated with multiple projects, and more professionals are needed, involving multiple specialties, which increases the number of works.
5. Technical Issues in Electromechanical Installation Engineering Construction (1) Drawings before the start of electromechanical installation. Design requires strict construction drawings, understanding the construction project, conducting comprehensive and careful analysis of errors and problems, keeping proper records, and pointing out and correcting them, striving to control possible errors from the source. Key points in drawing review include: whether the electromechanical construction plan and civil construction plan are consistent; Check whether the specific location, size, and dimensions of the electromechanical equipment meet relevant requirements, and whether there are errors in the number or diameter of wires between the floor plan and the distribution system diagram. At the same time, check whether the drawings meet relevant quality standards and technical requirements, and whether there are comprehensive safety measures for electrical use.
(2) Power Cabinet Installation: The installation of distribution boxes and cabinets is generally arranged after the completion of the civil construction floor. During specific installation, ensure accurate installation positions, uniform cuts, and complete assembly of related components. For dark distribution boxes, the box cover should be close to the wall, with the neutral wire of the combiner strip running through it. At the same time, check for any jamming conditions, set a clear number of cycles, and if there are too many cycles, use auxiliary tools to bind them to the package to ensure the inside and outside of the board remain tidy.
(3) Cable laying: Wide cable laying range: In electromechanical installation projects, before formal installation, the cable model, specifications, and performance must be inspected to ensure the specifications meet design requirements, have a complete appearance, pass wet tests, and have good insulation performance before being put into use. To ensure the cables can continue to be used in the future, insulation testing must also be conducted to guarantee high sealing at the sealing ends. During construction, when laying low-voltage power cables, high-voltage control cables, and high-weak cables separately, the principle of bottom-up should be followed. When the cable and control cable are constructed on the same side as the bracket, the force cable should be placed above the control cable. At the same time, it is also necessary to strictly follow the installation process flow, selecting professional technicians to fabricate the terminal ends and intermediate joints of the support cables, ensuring continuous peeling and cutting from to fabrication to prevent moisture damage, which could negatively affect cable performance and quality.
(4) System commissioning System commissioning is an essential technical control step in the later stages of electromechanical installation. Its function is to check the installation status of wiring and verify whether the quality and performance of electromechanical equipment meet design requirements. In this stage, it is necessary to focus on checking whether each process meets relevant usage standards, whether it does not meet normal operating conditions domestically, whether there are defects, and carefully prepares trial operation reports to make adjustments for unqualified or defective areas to ensure the normal operation and effective use of electromechanical equipment.
