摘要
The present invention relates to a foam tube for connection connection of a cast iron pipe and a hume pipe used for civil engineering construction. The conventional foam tube is made of rubber, synthetic resin, etc., and can not be used because of the weight of the pipe when it is used as a heavy pipe In addition, there is a problem that the foamed chemicals stored in the tube are highly reactive. Therefore, the time required for the manufacturing site to be used up to the field construction site sometimes takes several months. In this case, The separation tube 19 is separately inserted into the tube 1 reinforced by the reinforcing knitting yarn 5 and then picked up by the collectors 3 and then the separation tube 19 is inserted into the separation tube 19, The foaming agent is stored in the foaming auxiliary container 16 through the hose 17, It is a solution that can be solved even if it is given, and it is an invention that provides a perfect method for connecting the pressure tube.
