The connection of electricity, water supply, sewage and heating networks is an integral component in the construction of any modern building, and in construction terminology is indicated by a short phrase external network laying.
Construction it can be cheaper if the manufacturer has his own equipment, tools, applies modern materials, uses advanced technologies. The principle of reliability and durability is laid down during the development of the project, and is carried out at the stages of installation and commissioning, as well as in pre-launch tests of any types of laying of external networks, so it is better to cooperate with professionals.
External network laying sometimes accompanied by the dismantling of worn communications. Almost all engineering life support systems in the city are underground. Hot and cold water, gas, sewage, all the necessary benefits of a civilized life pass underground through pipes. The solution to the problem of new networks sometimes intersects with the destruction and repair of old, but still functioning.
The laying of an external water supply often requires the preparation of trenches and the installation of wells with shut-off and switch valves. A mandatory element is the waterproofing of wells and the device "pears". Trenches are covered with gravel and sand mixture with layer-by-layer compaction of soils at the intersection with sidewalks and roads.
For trenchless laying of external networks, a special set of pneumatic, electrical and manual tools is used. Wherein; special attention is paid to the study of previously laid communications, which is carefully noted at the design stage.
The laying of external heat supply networks is included in the overall design of the communications system, where all possible heat losses are taken into account and minimized. If the heating system is autonomous (for example, in a cottage village), it is necessary to adapt the boiler of the heating system with an electric or gas network. Autonomous heat supply is gaining more and more supporters; today individual heating systems are installed even in multi-storey buildings.And this is connected not only with ecology and energy conservation, but also in many respects with the dilapidation of existing utilities.
