Drainage wells are designed to provide access to storm sewer and household household systems. The innovative structure of structures is a worthy replacement for concrete products, having a lower cost and high durability. In addition, system maintenance costs are reduced.
Drainage wells provide access to non-pressure sewer networks for their maintenance, creating additional connections and changing flow paths.
Drainage storm water inlets are designed to collect water from parking lots, roads and other surfaces. The devices are equipped with a sedimentary part, where garbage and sand accumulate, as well as an outlet for draining rainwater into sewage systems. For example, the Pipelife plastic well system is available. The main feature of this model is its prefabricated structure.
The following types of drainage wells are distinguished.
Swivels are designed to periodically clean the system using water pressure. Such wells are usually mounted at every second turn of the system, or in places where drainage pipes meet. Thanks to this, you can conveniently simultaneously reach the outlet and inlet pipe sections.
Rotary systems have various sizes: from small ones that are designed to flush pipes, and to large ones that allow a person to go downstairs for the purpose of prevention and inspection.
Inspection drainage wells create conditions for monitoring the status of drainage systems. The devices are created with dimensions that make it easy to get inside and directly examine the state of the system, as well as eliminate all malfunctions. Inspection structures can be combined with other systems. However, their application is not always required.
Absorption drainage wells are built on drained territories in cases when there is no possibility of moisture removal to the main sewer or other drainage sites. This system has a simple design. The device is a container in the form of a pipe, which has a diameter of about one and a half and a depth of at least two meters.
It is covered with boiler
slag, crushed stone, broken brick or gravel, which is covered with geotextile on top and laid with soil. Similarly, backfill is carried out at the outer walls and the base of the well. Water from the absorption device leaves naturally in the lower horizons of the soil.
Another type of drainage system is water intake wells. They serve to collect moisture from the soil if there are no spillway sites nearby, and it is impossible to place an absorption device for technical reasons due to the high level of occurrence of groundwater or an inappropriate type of soil. For the operation of water intake wells, drainage pumps are used, with the help of which water is pumped out. Water intake wells represent a construction in the form of a pipe ending with a bottom, closed with geotextile and sprinkling.
