Do four-star hotels have to set up pipeline wells? Is there a standard?

Whether to set up a four-star hotel is not directly related to whether it is a four-star hotel. Sometimes, some pipelines in the building may not be in the tube well, such as electric wires, those buried in the wall may not be there, and fire hoses may not be on different floors. But if the hydropower pipeline is not in the tube well, other problems will be great, mainly fire prevention and maintenance. Generally, each floor needs to be divided into different fire zones. If the wires are laid openly instead of in the tube well, it will become a weak opening through different fire zones, which is not allowed. But if it is laid secretly, it can't be opened for maintenance at any time, so we can't smash the wall without any problems. If a tube well is set, you can open the fire door of the tube well and enter the well for maintenance when maintenance is needed. Therefore, the pipeline well is the best way to give consideration to both fire prevention and maintenance.
