4.1 Soil excavation
CAUTION
Note the structural calculations for traffic safety.
Chamber installation for load class D may require
a load distribution plate made of concrete: 0.18m x
2.3m x 2.3m (thickness x height x width).
Determine the required load class and structural
calculations in accordance with the environment /
use conditions.
Comply with the standard road construction /
cross section build-up in accordance with the
local road construction regulations (in Germany
the RASt guidelines ("Richtlinien für Anlage von
Straßen"), in the UK the Highway Design Man-
ual, etc.).
Ensure suitability of product (variant) for environmental
conditions (see "Intended use", page 19) and installation
depth (see "Product description", page 20).
Define slope angle β to DIN 4124
Excavate pit. ensure a working space of at least 50 cm all
around the base.
Compact the surface (30 cm blinding layer) and level it
off.
4.2 Chamber installation
Insert the chamber and align it horizontally.
If necessary, fix the chamber in place vertically using lean concrete.
When installed in groundwater, secure the chamber against buoyancy.
Backfill the remaining space (see "Fig. 1: Soil excavation", page 24) in sections using 0/16 fill material. After every 30 cm
compact to DPr = 97%, up to the height of the ground edge or standard road structure.
4.3 Pipe connection
Connect inlet pipe (note gradient, use socket if necessary)
Insert cable duct.
Insert ventilation pipe (route pipe to above the roof).
