Title Main Cooling Line Feeder
Description This is a main line feed of cooling water running from one of the pumping barges, thru a longitudinal inspection gallery in the dam. The hose connections are fastened to headers for the various coils of cooling pipe embedded in the concrete, thru which water from the river is being circulated. The flow was distributed so that at least 4 gallons per minute was passing thru each coil at all times. At a low point in the system booster pumps forced the water back over the cofferdam into the... Using one of the many ideas developed during the construction of the Boulder Dam the Concrete was cooled by means of two cooling water barges pumping water thru the 375 miles of one-inch pipe embedded in the concrete of the Grand Coulee Dam. Here is shown the main line for this network of cooling pipes meant to keep the concrete from buckling or cracking due to excessive heat expanding its mass.
