3.23.9.3 HOSE PIPES
Multiple connecting hoses are often connected
with hose pipes in the mobile restoration
operation.
The hoses are usually carried on a specially
equipped truck-mounted concrete pump, laid
before use and removed again after use.
3.23.9.4 INSTALLATION AND OPERATION
OF A HOSE PIPE
The installation of the hose line, as well as its
operation, requires special care and expertise.
DANGER
Danger to life due to flapping hoses!
Block off the danger zone and fix the hoses,
cover hose in a suitable manner if required!
In order to avoid a premature failure and
possible accidents, ensure the following:
- Only use flawless, clean hoses, couplings,
seals, etc. of the same system to structure a
hose.
- The maximum possible concrete pressure
may not exceed the max. permissible
concrete pressure of the pumping line parts.
- The concreting personnel at the placement
site must be informed about possible dangers
and be familiar with all necessary work.
- Place hoses with widest possible radius - Do
not bend.
Too narrow radii cause a one-sided abrasion,
bends will destroy the hose in no time.
Narrow radii and bends favour clogging and
cause the hose to pulsate.
- Do not pull hoses, especially not over sharp
edges.
- Do not twist hoses.
- Do not allow hoses to hang loose.
- Do not beat on the hoses.
- Place hoses and fasten securely with belts.
Do not use incising fixing parts.
- Do not drive over hoses. Place hose pipe in a
protected manner.
- No unauthorised person may remain near the
hose pipe during pumping operation.
- Moisten hose with water, then pump with flow
mixture.
- It is imperative to observe the maximum
aggregate size, depending on the nominal
sizes of the hose.
- Pump with lower delivery rate, hose must not
be disrupted.
