| In the north park Duesseldorf, in the quarter
Stockum lies beside the Aqua zoo the here eschriebene
well plant. The well was established in the 30's.
A restoration of the plant was now necessary.
The well plant sits down from the fontaene been
on higher level in the center of the park (upper
well plant), which semicircular head basins with
its three water stages and finally that 160 m
long and 16 m broad long basins also on each page
ten semicircular basin projection (lower well
plant). Arc-shaped water jets from both sides
form a long water tunnel. |

| From the remarks specified above now in the
following described work became necessary. The technology
in the eastern pumpenraum, which supplies the lower
well plant, was completely dismantled and was disposed.
The pumps were renewed and the pipe system inclusive
center for the lower well plant again, made of high-grade
steel were manufactured. Executions in the well
basin were selected in close coordination with the
reorganization of the basin and are contained in
the range TGA. The lines within the basin to be
dismantled, stored temporarily and after reorganization
of the basin again brought in, since these became
implemented already in high-grade steel waren.Im
apron for this in both well basins the nozzles accurately
measure, thus after completion of the overall renovation
the same optical picture of the fontaenen be ensured
could. In contrast to the lower well could be used
the pumps in the western pumpenraum and in high-grade
steel already implemented the pipings upper wells
again. The pipings in the center, not installed
yet in high-grade steel, and the lines in the well
basin were disposed and implemented in high-grade
steel. The controlling of the entire well technology
was realized by the trade electrical. For this logic
modules were used, which head for freely parametrierbar
the individual pumps over relays and line contactors.
Both the structure of the distributions, the installation
and programming of the logic modules belonged to
the capacity of the trade Elktro. To the ventilation
flushing and for dehumidifying the technique areas
a fan with duct system and pertinent control engineering
was installed. A goal was to be prevented it by
steered air agitation a drying process of the areas
too received and thus to mould and corrosion. |

Upper
well plant
The upper well plant consists of two concentrically
into one another with different Hfhe arranged,
round a'berlaufbecken, in a square basin
with rounded off corner areas stands.
The two round basins feed the square basin

Lower well plant the lower well plant consists
of an almost semicircular basin, overflow cascades
and one approx.. 160 m x 16 m long basins with twenty
in pairs arranged konchen.
Cellar area Underneath the well basins cellar area,
in those the electrical operating seams, lies which
pumping and the equipment technology are installed.
The entire underground part of the well plant is
opened by a round entrance in the brick wall specified
before. With the underground buildings there are
two ranges. The western range with vie areas under
the upper well range, and the eastern range with
three areas under the semicircular basin of the
lower well range. Courses connect the two ranges
with the entrance. Under way between the western
and the eastern cellar areas there is one ontageschacht,
which is covered by a soil-same construction with
the and stone lying here in the upper place range.
The assembly pit leads to the course, which connects
the two parts of the well plant. At the western
end of the course, directly before the upper well
plant, is a light pit, which is covered with glass
components. When assembly assembling and the light
pit moisture penetrations and plant vegetation were
to be determined. The room climate in the basement
area was characterized by a very high air humidity
and a relatively low Temparaturen. In some places
water condensed and formed drops. Humidity occurred
particularly by the leaky pits (light and assembly
pit). A ventilation was only ensured by smaller
joints and cracks e.g. with the eingangstuer. A
ventilation system was missing. The underground
areas were drained over one lower at the eastern
end of the course in the input area of the there
areas. The entire course along a gutter was trained
in the soil, which lowers resulting water supplied. |
