ABSTRACT:
A well point assembly is provided having an elongated flexible header pipe with a plurality of coupling joints attached thereto for attaching wellpoint assemblies. A flexible header pipe reel stores the flexible header pipe when not in use and allows the header pipe to be reeled off and positioned around an excavation site. A flexible wellpoint header pipe distribution reel is provided having a wheeled transport having at least two wheels. An axle has two wheels attached thereto and each wheel is rotably separate from the other wheel. The flexible wellpoint header pipe reel is mounted to the axle and rotable relative to the wheels. Reel handles are attached to the reel for rotating the reel relative to the wheel and flexible wellpoint header pipe is wrapped around the reel and is adapted to be reeled off responsive to rotation of the reel. The wellpoint header reel includes a lock for locking the reel and at least one wheel together, and the ratchet and pawl mechanism, which can be shifted to allow the reel to rotate in either direction relative to the wheels or can be shifted to allow the reel to rotate in either one or the other direction relative to the wheels.
