HEAT EXCHANGING PIPE PROTECT CAP AND CONSTRUCTION METHOD USING THEREOF

摘要

The present invention relates to a protecting cap combined with an iron mesh and a heat exchanging pipe composing a cast-in-place pile of an underground heat exchanging system and a construction method using the same. The protecting cap comprises: a cap body unit having an outer diameter corresponding to the diameter of the cast-in-place pile, and a hollow at the center; an iron mesh hole formed on the cap body unit for allowing the iron mesh to pass through; and a pipe hole formed on the cap body unit for allowing the heat exchanging pipe to pass through. The protecting cap is inserted into the top of the heat exchanging pipe and the iron mesh which have been completely installed.
