Generally, wells must be installed at corners, branches or where the laying method is changed. The length of the straight section should not be greater than 100 meters.

When selecting the location of the shaft, the following factors should be considered:

1. Directly close to various equipment rooms

2. It must not be adjacent to elevator shafts or pipe shafts *Use the same shaft. Weak current and strong current lines should generally be installed in weak current shafts and strong current shafts respectively. If they must be used together due to conditions, weak current and strong current lines should be arranged on both sides of the solid well or isolation measures should be taken to prevent strong current from interfering with weak current.

3. Avoid being near flues, heating pipes and other facilities that dissipate large amounts of heat or are moist.

4. When conditions permit, avoid being adjacent to elevator shafts and stairwells. Extended information

The equipment, pipelines and bridges of all intelligent subsystems are arranged in the weak current shaft.

For example, the automatic fire alarm system has various control modules, terminal boxes, fire alarm buses, linkage buses, manual start and stop control lines for important fire protection equipment, fire telephone lines, and fire broadcast lines set up on each floor. For buildings with computer network systems, weak current shafts on each floor also serve as floor equipment, with floor network switches, distribution frames, etc. installed inside. The shafts are not just shafts for routing cables.

Sometimes telephone distribution boxes, TV distributor boxes, etc. are also installed in the vertical shaft. Therefore, for buildings, shaft closures are indispensable. Not only must they exist, but they must also have a certain area.
