WOODEN PENSTOCK WEB PAGE
Ruptured wooden penstock during the peak of a freshet. Note the river WSE is at the spring line of the penstock.
Broken bands and blown out wood stave.
This is how we patched the opening. We squared off the ends with a wood auger and a sawzall. We cut and fitted a new piece of Douglas Fir. We sledge hammered the piece into the opening. We fabricated an inner and outer steel plate and match drilled the edges of the two plates. We through bolted the plates using tap bolts (the bolts are threaded to the heads with no shoulders). We added new steel bands. This is an external view.
This is an internal view of the patch.
