ABSTRACT:
The invention is directed to a concrete distribution system for transportable concrete and includes a concrete conveying pipe line of several pipe sections and a pipe line carrier boom of several carrier boom segments. The concrete distribution system is so configured that it can be conveniently used in spatially limited construction sites such as tunnels. This is achieved in that pipe sections (6, 8) are connected to corresponding ones of the carrier boom segments (4, 5). The pipe sections are telescopically engaged with each other and the boom; segments are likewise telescopically engaged with each other. The pipe sections and boom segments are extended and retracted in tandem.
