1. Construction environment
Generally, after the cable trench cover is installed, the entire project is still in the large-scale construction stage, so the construction site must be maintained to ensure the safety of the construction personnel.
2. Cable trench erection and molding
This is the basic condition for laying the cable trench cover. If the cable trench cover is not laid, it will cause a huge workload in the later stage, and may even cause large-scale rework, waste manpower and material resources, and generate unnecessary costs.
3. The basic work of the cable bracket has been completed
Before laying the cable trench cover, the cable support must be treated with anti-corrosion and the stains left by the previous construction must be removed. If there is no anti-corrosion treatment, the cable support is easy to rust in rainy days and the shelf life will be shortened. Decontamination is to ensure the smooth progress of the cable trench laying process of the cover plate.
4. The equipment installation in the cable trench is completed
Cables and fire-fighting devices need to be installed before laying the cable trench cover. This is to reduce the workload in the later stage and protect the safety of construction personnel. If no fire protection device is installed, an accident is likely to occur.
