Sewer connections
Laying
The subbase of reinforced concrete slot units should correspond to that of
the adjacent carriageway. Reinforced concrete slot units must be laid on
frost-proof foundations. Depending on the traffic area loading and the property of the subsoil, the slot units are installed on a carefully compacted and
drawn off formation, a subbase layer or on an unreinforced concrete foundation.
If the adjacent traffic areas are made from stiff materials, e.g. concrete,
adequately dimensioned expansion joints (not dummy/shadow joints) must
be laid continuously along the whole height of the channel and along the length
of the slot unit. To avoid damage, we recommend use of our »System DEHA«
slot unit lifter, which we can supply to order.
General laying instructions are available to download from our homepage:
www.rohr.de.
In the event of unfavourable gradients, such a shaft construction can be
dispensed with. In that case, the reinforced concrete slot units can also be
directly connected to the drainage sewer. To this end, the shafts are available from the factory with integrated shaft lining for all the usual pipe materials and nominal sizes.
The maximum unit lengths given in the table therefore
result for the construction of radii (with a channel width
of 50 cm).
max.
effective length
The reinforced concrete slot units are connected to the drainage sewers
and drains by installing appropriate drainage manholes. These are combined
with road gulleys according to DIN 4052 and consist of a shaft, base with
DN 150, 200 or 300 mm outlet and a hot-dip galvanised sludge bucket. For
example, if a sealed shaft structure is required for environmental reasons,
we can also supply corresponding shafts with monolithic structures.
Our reinforced concrete slot units are equipped with
a removable plug-in connection in the form of a socket
and spigot. We supply wedge-shaped elastomer slip
rings as seals, which act as compression seals. These
are usually made from SBR material, but can also be
supplied made from EPDM or from NBR for increased
oil and fuel resistance requirements. The width of the
butt joint should be 5 to 10 mm and can be filled with
a suitable jointing compound after completion of the
traffic area construction. If laying radii, the channels
can be deflected so that a joint of 5 mm, (outside
15 mm) results on the inside

The outlet can be positioned laterally or in the direction of the drainage pipe,
less than 45° downwards or vertically. The distances between the connections must be adjusted to the size of the respective catchment/runoff area.

Manufacture / load bearing capacity
Support/bedding
Our reinforced concrete slot units are produced in precisely dimensioned
steel formwork. The concrete recipe used is continuously optimised with
respect to durability, taking into account state of the art engineering standards. Rebar steel BSt 500S/M is installed as reinforcement.
We use C50/60 concrete for our reinforced concrete »Pfuhler Rinne« slot
units. Its composition, production and use corresponds to a concrete to EN
206-1 and DIN 1045-2 and DAfStB guideline for self-compacting concrete
(Issued November 2003).
It is suitable for exposure classes:
XD3 - Reinforcement corrosion induced by chlorides, other than from seawater, environment is cyclically wet and dry
XF4 - Freeze/thaw attack with or without de-icing agents, environment with
high water saturation and de-icing agents
XA2 - Concrete corrosion induced by chemical attack, Moderately aggressive chemical environment, (except chemical attack by sulphate >
600 mg/l)
Class D 400 channels correspond to Type I to EN 1433; i.e. they do not
require a foundation to absorb loads in the installed condition to dissipate
the loads that occur during use. Class F 900 channels correspond to
Type M. They must be laid on a structurally calculated reinforced concrete
foundation.
Hydraulic performance
The slot unit can be considered as a pipe for the purposes of the hydraulic
calculations and the design carried out according to Prandtl-Colebrook. Flow
rates for the respective longfall are given in the diagram below.
The maximum distance between the inlet shafts/gulleys is calculated from
the flow rate for the given channel gradient divided by the lateral inflow per
meter length.
Due to the high concrete strength (C50/60) in conjunction with the high
tensile strength of the reinforcing steel used, reinforced concrete slot units
can safely withstand the static and dynamic loads that occur.
Constant, comprehensive quality assurance consisting of self-monitoring
and external monitoring ensures a consistently high quality standard.
According to EN 1433, drainage channels are classified in load classes
analogous to manhole covers. The classification is made by means of a load
test. We regularly subject our reinforced concrete »Pfuhler Rinne« slot units
to appropriate load tests, together with a certified test institute.
However, on request, we can also supply reinforced concrete slot units
whose load bearing capacity is additionally verified, taking into account the
respective loading and installation conditions according to accepted good
reinforced concrete construction practice (DIN 1045-1). Road traffic loads
are applied according to the DIN report 101, loads on airfield and airports
correspond to the recommendations of the »Arbeitsgemeinschaft Deutscher
Verkehrsflughäfen« (ADV).
The following is a comparison between EN 1433 classification and the
