Water well: device, advantages

Water wells are designed to install equipment such as cranes, latches, fire hydrants. As a rule, they are made of prefabricated reinforced concrete, less often of brick. They come in different sizes and shapes.

Reinforced concrete structures

The water well can be either round or rectangular. It is made for pipes of the following materials:

• reinforced concrete;
• Brick and concrete.

Round structures have the following dimensions: 1000, 1500, 2000 mm. To all these dimensions, a diameter of 1250 mm is added, if there is a brick in the structure. The maximum size of the well, which has a rectangular shape, is 4500x4000 m.

A water well consists of a reinforced concrete slab, which is installed on a compacted soil. A prerequisite is the horizontal position of the plate, otherwise the ring construction will not stand. At the point of insertion of the pipe into the well, the sleeve should be installed, if it is made of PVC. This must be done in case of draft of the well, so that there is no breakthrough.

The water well is placed depending on the depth of the pipes. At the top of the construction, a ring with a hatch is installed and the neck is laid with a brick. Great attention is paid to quality external waterproofing and proper drainage system. Usually blocks are covered from the outside with bitumen, however this method is a bit outdated.

When constructing a water well, new materials are being used for waterproofing. You can use RubberElast ribbon or rope (hemp, jute or linen). The rope is not necessarily impregnated with bitumen, or it can be smeared with fibrorezin Kiilto Fiberpool. This is a special mastic, which is used as a waterproofing.

Polyethylene tanks

An alternative to the concrete structure is a plastic water well, the price of which is much lower. Polymer systems are becoming increasingly popular due to not only the cost, but also the reliability of the material.

Welded plastic tanks, depending on the functions performed, are divided into:

• Inspection;
• Storm showers;
• Sedimentary;
• For locking equipment;
• For measuring instruments.

Plastic analogues in comparison with reinforced concrete structures have the following advantages:

• The probability of displacement due to groundwater is excluded;
• Accelerated installation of the structure;
• Light weight;
• Low thermal conductivity of the material ;
• durability;
• Impact resistance;
• Resistance to mechanical damage;
• Frost resistance;
• Not susceptible to corrosion;
• A large selection of designs.

Such systems are also popular because the installation of water wells can be done independently. Welded tanks are manufactured at the factory. The order can be made in advance, and the system will be made in exact accordance with it. The tightness in this case will be much higher. Additional products can be added to such products.

Sufficiently convenient is the arrangement of a sealed chamber for water supply, since the system operates under pressure.
