The trend towards using space underground in cities has a long history. Even in ancient times, our ancestors successfully located their defensive and cult equipment, secret passages, housing and various storage facilities. The underground infrastructure began to develop actively after the appearance of the corresponding engineering support. Now it is difficult to list everything that can be found in the space under the ground of the city. However, all structures can still be divided into several categories.
Categories of underground objects
Absolutely all networks and engineering equipment belong to the first category. The most common are plumbing systems. Water supply infrastructure includes all water disposal systems: domestic and industrial sewerage systems for their drainage.
Not only pipelines for communications, but also heavy equipment are often located within the city. Often, such equipment is installed in large underground structures. Inspection rooms are deepened to a certain depth, and pumping stations, pumping stations and heating points are also located underground.
They also lay most of the systems for steam and gas pipelines, which are equipped with special equipment, which are often hidden underground. Tanks are often erected below the earth's line to store large volumes of water and other types of liquids, sometimes even gases.
In the engineering economy of most cities, power supply systems and various communications are being built underground. In most cases, fiber optic cables are used to transmit information below ground level. Transformer equipment is often buried in the ground.
The future of the dungeon
There is important information that as a result of the rapid prosperity of technology, engineering systems also continue to develop successfully. In our time, it is very difficult to predict what new equipment will give us by the end of the 21st century. For example, today there are already several loyal systems that are capable of moving solid waste. Such systems are still operating only within the boundaries of a block or residential group, moving various garbage to packing or recycling stations. Underground defense factories are now successfully operating. Sometimes entire workshops and laboratories are buried in the ground, which need to be protected from noise or dust.
