5.4.2 Splitter types C9, C10S, C12
Expanding with expander pressure pieces
Fig. 5-4-2 - 1 Expanding with expander pressure pieces
To expand a split with these spitter types, the normal pressure pieces are succes-
sively replaced by thicker expansion pressure pieces. After each splitting or expan-
sion process, the split must be secured e.g. with an iron wedge. To achieve an es-
pecially large splitting distance, the special expansion pressure pieces are avail-
able for the types C9 and C12. Exchanging the pressure pieces:

With heavily reinforced or qualitatively poor concrete, it can happen that only com-
pression will take place around the borehole during the splitting of the concrete.
This problem can be resolved by using two large-surface pressure shells that are
available for the types C9 and C12. A borehole with a 100 mm diameter must be
drilled for use of the pressure shells. With regard to the depth of the boreholes,
please heed the information in the chapter Technical Data!
Expanding with pressure shells and expansion pressure pieces is also possible.
