摘要

Station for retention of boulder detritus, particularly in a canalisation system, has inlet and outlet apertures for a shaft (2) handling waste water, which has a deepened section (8) for the deposited detritus. In the shaft is an insert (10) withdrawable for emptying and which receives the detritus in a container part (11).
