Installation of external engineering networks and communications
It is unthinkable, than residential or industrial building projects could be completed without the work of external engineering networks and external engineering communications. Usually the customer does not skimp on the quality of work and the cost of materials. It is obvious that the engineering networks and communications are held not for a year, ideally, for several decades. Work on installation of external engineering networks and communications require a high skill of the builders.
Work on the external engineering communications and Networks - is a large range of various works from the trays setting up to water supply systems laying (including wells, fields, end walls, shut-off valves).
First of all these works associated with the pipeline.
Before you go lining thermal networks, water pipelines laying, sewer networks laying, it is necessary to clarify the possible occurrence of high-voltage cables and circuit engineering networks and communications near the construction site. We should plan pipelines laying on the shortest direction with a minimum of additional buildings and do not forget the mandatory minimum space between the pipes.
Laying of heating networks can be monotube and multitube. As a rule, in the settlements we use two-pipe heating system, working under the scheme - one pipe delivers heat, and through the other the spent coolant flows back. In recent years pad heating networks of polymeric materials became very popular. Although this is a general trend that applies Heightening demand for water pipelines laying made of polymeric materials and sewerage networks of polymeric materials laying.
Laying of water supply systems as well as laying the pipeline require any preparatory works: soil analysis, planning ways of laying and much more. If laying of water pipelines is performing underground, pipes, traditionally, are chosen from cast iron, asbestos cement, steel, and plastics.
Laying of sewerage systems requires the prior determination of the pool drain, sewer network tracing, product hydraulic design, etc. The sewage network complex system. In a sewer system setting up we orient to the average consumption of water in accordance with the selected type of pipes (material, diameter, etc.).
