Differential wells

Differential wells are designed for:

  • reducing the depth the of pipeline ; allowing you to connect the channel at a level higher than the troughing part of the well;
  • avoiding exceeding the maximum allowable slope of the pipeline sections and as a consequence (a sharp change in the velocity)of coaste loater;
  • Installation at an intersection with the underground structures or at flooded outputs in the last well in front of a pond.

All types of wells presented above can be manufactured with differences in altitude.

Example 1.

Differential well with diameter (ID) of 1600 mm, well pit height of 5750 mm, inputs / outputs are made of corrugated pipes of 1200 mm diameter, the damper is located inside to absorb the flow rate of the transported liquid, also serving as a viewing platform and stairway (Photo 14). Production of differential wells according to Album № 5 «Stormwater chambers and wells. Typical materials for the design 902-09-46,88» is also possible.
