UNDERGROUND HEATING NETWORK IN FERROCONCRETE CANAL

摘要

The invention relates to construction. The purpose of the invention is to increase reliability, reduce heat loss, capital and current costs during construction and operation. The network contains a direct pipeline 1 for supplying hot water and a return pipeline 2 for returning the cooled network water. Pipelines 1 and 2 are laid on supports 3 in reinforced concrete channel 4 with reinforced concrete floor 5 and bottom 6. Along the length, channel 4 is separated by a hollow partition 7 for separating the air heat insulating layer 8 of direct pipeline 1 from the air layer 9 of the return pipe 2. This excludes heat exchange between them. At the entrance to the heat chamber, channel 4 is provided with a blank reinforced concrete partition to prevent movement of air gaps 8 and 9 through the channel, which prevents convective heat exchange through them. The bottom, e 6 of the channel 4 has through holes 12 for leaving into the ground 13, showing the position in the channel 4 of water. All portions of overlap 5 are stacked with horizontal locks, made with a gap for drainage outside the channel of surface moisture that has seeped into the lock. 2 hp f-ly, 3 ill.
