Laying of plastic pipes that follow the instructions in Svenskt Vatten P92
The installation instructions in this brochure follow the instructions in Svenskt Vatten P92
There should be between 1-2 cm drop per meter and if the drop needs to be increased, it should be done in steps to ensure that the water does not run off the paper.
In vertical falls, it goes just as fast, hence the steps.
SHAFT
The width of the pipe trench must be large enough to allow working space for packing and tamping the pipe.
The recommended minimum distance, A, between the shaft wall and the pipe is:
Pipe diameter, DN A (cm)
400 35 + 0.25 x D
SHAFT BOTTOM
The shaft bottom must be smooth and free of stones and adjusted to the correct height and slope. Unevenness in the shaft bottom, e.g. where stones have been removed, is filled with a leveling layer.
CONDUCTOR BED
The conduit is laid on a bed of sand or gravel (material type 2 or 3B, see page 9). The bed should be 15 cm thick and at least 10 cm thick at the joint. The bed is compacted before pipe laying according to the table on page. 9.
Alternatively, the bed can be compacted indirectly by compaction in the support compaction zone after pipe laying. In the case of indirect compaction
ensure that the pipe is not disturbed in height.
CIRCULAR FILLING
The pipe is underfilled after laying to a height of
0.2 x D and then filled in layers of 10-20 cm, but not more than 0.5 x D, up to 30 cm above the top of the pipe.
Make sure that the pipe is not disturbed in height when underfilling and packing. Carefully place the filling material with a bucket from the lowest possible height. Do not tip the material directly onto the pipe.
CIRCULAR FILLING MATERIAL AND PACKING
Circular filling of pipes is best done with one of
the following materials:
Material type Material
2 Gravel, sand, crushed stone
3B Silty sand, silty gravel
Material type 2 is recommended in the first instance.
Filling material must have a maximum grain size of 32 mm.
Frozen material must not be used.
Maximum layer thicknesses (m) for compaction are:
Material type 2 3B Min. number of
passes
Vibrator ram, 70 kg 0.30 0.25 4
Vibrator plate, 100 kg 0.15 0.10 6
Vibrator plate, 200 kg 0.20 0.15 6
When compacting fill over a pipe, the layer thicknesses specified in the table must not be exceeded.
RESIDUAL FILL
For pipes in roads or streets and under buildings, the material and compaction of the residual fill must be carried out in the same way as for the pipe’s peripheral fill, see p. 9.
For pipelines in natural ground, excavated material can be used and compaction is not required.
Stones up to 300 mm in size may be evenly distributed in the remaining fill. In the remaining fill that is compacted, the largest stone size may be a maximum of 2/3 of the layer thickness after compaction.
