Intze Principle

Two different design principles are called Intze principle. Both go back to the water Bauer Otto Intze ( 1843-1904 ). The one Intze principle refers to the construction of a water tower, the other on the construction of a dam.

Intze principle for water towers

A built according to the principle Intze water tower has a water tank with a bottom, which is designed with sloping downward and centered arched upward, which enabled a particularly slender supporting structure of the tower. There are thus no horizontal forces, but only vertical forces introduced into the tower shaft, which can be designed, therefore, less massive. This design was used in Germany 1885-1905.

Intze principle used in dams

The dam construction by Otto Intze was applied late 19th century and early 20th century in Germany. A built after Intze principle dam has the following features:

• It is a gravity dam with a nearly triangular cross-section.
• The wall consists of masonry with a high proportion of mortar.
• It has an arc-shaped floor plan.
• She has a water side intent masonry ( blindness ) at the top.
• It has a water-side embankment of clay, the " Intzekeil " at the bottom.
• It has a sealed concrete with water side and on a natural asphalt ( tar ), Inertol or Siderosthen paint.

The Intzekeil is estimated today to be ineffective.
