4.3.2 Pipe connection
Check the pipes, gaskets and fittings as described in § 6.1.6-7-8-9.
Lay the pipes and avoid them from twisting during material conveying. The first ten metres of piping are subject to oscillations
(a few centimetres) during transport: it is advisable to raise this section from the ground and prevent it from resting on edges or
abrasive elements.
Anchor the pipes properly:
- Horizontal pumping
Lay piping as desired and connect it to the first section previously described to pump material horizontally.
- Vertical pumping
The vertical piping section must be fixed and supported using the appropriate collars (FIG. 4-11).
- Downward pumping
The downward piping section must be fixed and supported using the appropriate collars (FIG. 4-12).
Arrangements must be made to stop the concrete fall in the downward section (e.g. assemble a bend or S-bend - as in FIG.4-
12 or make tilted sections). For this type of layout, we recommend lubricating pipes with grout as follows:
- introduce two wash sponges in the piping's initial section (FIG. 4-13).
- Pump the grout. The entire internal surface of the downward section will, in this way, be lubricated.
Introduce more sponges and more grout if the downward section is particularly long.
