Karl Manck

Karl Friedrich August Manck , also Carl Manck or Karl Mank , (* 1838 ; † November 15, 1888 in Dresden ) was a German civil engineer and construction clerk .

Life

Manck studied civil engineering from 1852 or 1853 to 1858 at the Royal Saxon Polytechnic School in Dresden . After completing his studies, he worked in the Saxon Royal Hydraulic Engineering Directorate in Dresden, initially as an unskilled worker and later as an assistant and conductor . In 1865 Manck moved to the Dresden City Planning Department and, as a senior engineer, was in charge of the city's road and lock construction and water supply systems. From 1872 he was responsible for the planning and from 1875 to 1877 for the construction of the Albertbrücke in Dresden. On the occasion of its opening, he was awarded the Order of Albrecht 1st class. Manck was also involved in the planning of the First Carolabrücke , which was destroyed in World War II (built 1892–1895).

From 1878 Manck headed the newly established civil engineering department in the Dresden City Building Office. In this function, he was responsible, among other things, for the new construction and paving of streets and squares as well as the vaulting of the Weißeritzmühlgraben .

Scientific work

One of the focal points of Mank's work was his theoretical work on general drainage planning, which also found its way into the relevant specialist literature. He also published essays on the compressive strength of concrete (around 1878), the hydraulic calculation of sewers (1884) and a steam roller construction (1887), for which he was also a patent holder, in the Deutsche Bauzeitung .

Expansion of the Dresden sewer system

Another focus of Manck's work was the planning and expansion of the Dresden sewer system. In the early 1880s, for example, he introduced concrete as a sewer construction material and standardized the previously diverse cross-sectional shapes of sewers.

His "sluice systematisation project" presented to the Dresden city council in 1867 together with city planning officer Theodor Friedrich embodied a first general drainage plan for the city, which was developing rapidly even before the start of the early days . The main network structures designed in it were largely realized structurally, but a short time later no longer met the requirements. In particular, it turned out to be a wrong decision not to make the washing-off of faeces with the wastewater - which is a matter of course today - for hygienic reasons and because of its then usual and financially worthwhile use as fertilizer as a principle of its planning.

Some sections of the sewers built in the 1870s had to be dismantled or rebuilt by Manck's successor in office, Hermann Klette . Regardless of this, around 65 km of these old canals were still in operation in 2016.
