What Does Receiving Pit Mean?

A receiving pit is an excavated pit, an opening located at the exit of the cutterhead or casing, which is the destination point for a pipe jacking or microtunneling operation. The receiving pit is used to remove the equipment and spoil from the microtunneling process when the bore is complete. Receiving pits are minor excavations compared to digging open trenches along the full length of pipe installation.

Also referred to as an exit pit.


Trenchlesspedia Explains Receiving Pit

A pipe jacking or microtunneling trenchless installation has a beginning point, desired route and ending point. Pits must be excavated at the beginning and ending points in order to make room for the equipment to be positioned for the boring process. Once the bore is complete, it is not possible to remove the drill and drill string through the entry pit, as the pipe or casings would have been laid in the bore behind the drilling head. When the drilling head exits the ground through the receiving pit, the equipment can be disconnected and removed safely.
