During the construction of water supply systems and water supply wells used with precast concrete.

Water wells are designed to accommodate the water supply valve and its management, performance of repairs and maintenance.

The composition of the round vertical shaft reinforced concrete:

A. Bottom;

2. The working chamber (rings with seam compound);

3. Floor slab;

4. Neck;

5. Luke iron;

6. Obmostky plate;

7. Running staples;

8. Sealing rubber ring or a special basic resin composition "polishers";

9. Water pipe with special rubber gaskets;

10. Compacted soil, the base of crushed stone or concrete;

11. Waterproofing coating waterproofing emulsions and mastics.

Round observation wells used for water supply networks and diameter 50 - 600mm. Working height of 1500, 1800, 2100 and 2700mm diameter ring consists of 1000,1500,2000 mm.

All types of water wells have horlovynni Laz D = 700mm and overall height variable depending on the size of the cavity wells and performed with precast concrete rings with a diameter of 700mm.

In soils with high groundwater above the bottom of the well, carry waterproof bottom and walls of the well at 0.5 m above this level - for sandy soils, for clay soils - top waterproofing determined by the level of capillary rise of groundwater.

External insulation of walls, bottoms, floor slabs - obmaschuvalna of hot rubble, dissolved in benzene.

At the junction of precast concrete manholes seam connection is recommended to predict sticking polosok of polymer - bitumen membranes "BudRol" H width 20-30cm.

Mounting door should not allow penetration into the well of surface water. In the absence of hard cover, sunroof should appear above the ground 50mm. Equipment obmostky width 1m from the hatch with a slope of it can be done with a special reinforced concrete slabs.

In water wells, with an appropriate justification should include the installation of additional slabs for insulation. Covers a diameter of 610mm can be manufactured from steel or wood.

For the descent into the well on the inside surface of walls neck set steel or cast iron brackets, and working chamber, instead of staples can be used steel ladder.

All prefabricated elements wells installed during installation of cement-sand mortar grade 100, thickness 10 mm. Mounting rings with seam compound apply a special adhesive mixture "polishers".

In order to establish a ring of pipes vysverdlyuyutsya holes diameter 30-150mm.
