Building rubble discharge chute

摘要

The slightly conical pipes (1) fit telescopically inside each other and are suspended from at least one chain. At least one branch-pipe (2) is positioned at the junction of the pipes. A further discharge chute formed of separate pipes (1',1") open into the branch pipe. The centreline of the side inlets into the branch pipe forms an acute angle with the vertical drop direction above the branch pipe. The branch pipe has two or three inlets and one outlet. The outer top part of the branch pipe has at least one suspension (3). The pipe at the outlet of the branch has at least one suspension point (4). Preferably elastic baffle elements (5) protrude into the drop cross-section of the pipe branch.
