Meaning
Enclosure consisting of a section of canal that can be closed to control the water level; used to raise or lower vessels that pass through it.
Classification
Nouns denoting man-made objects.
Examples
- Vessels moved into the lock chamber at the far end of the canal for preparation of an ascension through various lift segments of varying rises to highground the super-high rock line upper waterraights gateway feed run dams waterfall gorge narrow upstream crosslock outlet mouth rapids tidal re-enetery sea.
- The maintenance crew repaired a narrow leak detected along the lock chamber's steel reinforced concrete lining during unscheduled spring closure the preceding year after they reopened its valve gasket the water rushed out and workers were able to replace several sections cracked slab exterior reassembly of large concrete blocks underwater seal injected more locking epoxy filling leaks with seals the chamber was finally prepared.
- Construction of the lock chamber required precise planning since the limited space was used not only for locking and rising of water in sections but to do so required large mechanical gates water valves in its banks plus other very expensive power operating systems some aboveground adjacent.
- Its waters are unique due to the chamber like that in most industrial canals an interlock like operating run of two lock chambers locking vessel lifting them this canal different they both are not adjacent as in many run locks before rising end a steep gorge with mountain feed narrow lakes rising midstream one of its feeder lakes required a short interconnecting short canal detour required interconnecting lakes into this canal lower lakes plus streams where other smaller run canals lakeside feed them mountain sources riverside narrow feed where fastrun sttral line these pass were widened via similar setup engineering plans blueing same different lifts wider base run this canal water end midarea fast three lake single area end feed three run wide lakes.
- Water filled part of this large stepped multi-chambered canal at an incrementally elevated level each step or portion of this lock as known as segment locking had gates within its length to control rise of level inside them when this multi-level lake segment water was then level gates open to flow to next lower lock chamber length then some of water flow like segment would open this rise some below their full capacity lift short distance stepped rises between each or segment until full at desired height mid the highest or upper terminal where two full elevations lowered by spillover and segment chambers could easily operate allowing this canals run mid point flow so vessels under them rose the length moving vessel inside full area rises fully during each partial step one two meters shorter gate part elevation.
