(57) Abstract:Use: in the construction of stock tanks clean water. The inventive cylindrical supporting tower installed in the fresh water tank on its axis and made of blocks-tubing with Windows in the bottom for the passage of water. Luggage with air filters installed in the upper part of the tower. 9 Il. The invention relates to the field of water supply and for water supply systems.Known water system containing pure water reservoir and the chamber with the air filters in the tank, placed in a separately located underground structure made of precast concrete blocks and slabs coating and having a common band with the tank.One of the drawbacks of this design clean water reservoir is a complex internal supporting frame, time-consuming to manufacture and full metal embedded items requiring protection from corrosion. This design does not allow to increase the height of the tank (or volume) due to insufficient bearing capacity and stability of the frame columns and circulation partitions.The design flaws soo is the efficiency of the allocation space in the sanitary area of a water supply facility to accommodate them (how many tanks so much of free-standing structures for filters-absorbers), the high cost of materials and the high estimated cost of the facilities, as well as the long lines from the filter to the upper part of the tank.The objective of the invention is to provide a water supply system consisting of one building, uniting the tank for clean water and room to accommodate filters of air entering the tank, eliminating the need for the construction of the circulation baffles inside the tank and the possibility of formation of stagnation zones of clean water when driving water flow inside the tank, and the creation of easily erected a powerful support structure inside the tank height, perceiving the load from the cover of the tank and structures for filters, absorbers, simultaneously performing the functions of the circulation partitions, and the exclusion of air by connecting filters air tank directly through the holes in the floor.This is achieved by the fact that the water supply system containing pure water reservoir and the chamber with the air filters in the tank, provided with a cylindrical supporting tower that is installed in the fresh water tank on its axis and made of Blin in the upper part of the support tower.In Fig. 1 shows a pure water reservoir, the cross-section of Fig. 2 is a plan; Fig. 3 camera with air filters, the plan of Fig. 4 section a-a in Fig. 3; Fig. 5 anchoring the abutment tower to cast reinforced concrete bottom of the tank; Fig. 6 section b-B in Fig. 5; Fig. 7 the layout of units cylindrical support tower; Fig. 8 junction block cylindrical bearing towers between them; Fig. 9 section b-b of Fig. 8.In the tank 1 the pure water of the water system, exterior walls are made of blocks-tubing, erected centrally located cylindrical support tower 2, which has in the upper part of the chamber 3 for accommodating therein, air filters, air ducts and valve control, and at the bottom of the pit 4 for placing a funnel water from the tank. Tower 2 is made of concrete blocks-tubing 5, connected by steel pins 6 and mounted with the formation of Windows 7 for the passage of water. Mounting blocks-tubing can be conducted in parallel or after the erection of the exterior walls of the tank 1. Communication tower with exterior walls of the tank during the Assembly of the tower are temporary metal link 8 (six pieces), rorke blocks tower steel studs with 6 nuts and washers are protected from corrosion of cement-sand mortar. The lower ring blocks tower 2 secure the anchor bolts 9 to the fixtures 10 monolithic concrete frame 11, which is welded to the metal beams 12 of the tank floor. Fixing the first ring of the tower to the bottom, you can perform any other known method. Monolithic reinforced concrete roof of the tower is on the same level with the floor of the tank and serves as the floor of the chamber 3. The overlap provided by the openings 13 for the passage of piping condensate is discharged from the filters and the opening 14 for inserting air into the tank. Camera filters are made of the same blocks-liners, but with brick insert and door opening 15. The coating chamber 3 of monolithic reinforced concrete with sleeves for the passage of air ducts. Roof structure and covering the camera with filters and tank are the same.In addition to reducing the estimated cost of construction of water supply system reduces construction time by reducing the total volume of excavation, construction and plumbing work. Increases safety during construction and installation works, because the invention provides for the execution inside the tank only one mounting operation, the mounting blocks-liners. Installation westview embedded parts and structures inside the tank eliminates complicated job to protect them against corrosion zinc coating (plating). The WATER supply SYSTEM containing pure water reservoir and the chamber with the air filters in the tank, characterized in that it is provided with a cylindrical supporting tower that is installed in the fresh water tank on its axis and made of blocks-tubing with Windows in the lower part for the passage of water, while the Luggage with air filters installed in the upper part of the support tower.
