<p>PURPOSE:To achieve rousing and line connection possibility test and line connection efficiently by eliminating water inside a ductwork by Coanda spiral flow and performing cleaning and then performing line connection of an induction wire inside the duct. CONSTITUTION:A compression air is supplied from a Coanda slit 4 of a Coanda spiral flow unit 3 toward a ductwork 1, thus generating Coanda spiral flow, eliminating water in the ductwork 1, and then performing cleaning. In this case, a suction introduction port 6 of the Coanda spiral flow unit 3 is closed by a lid device 11 and then water of the ductwork 1 is eliminated, etc. Then, a specific cable induction wire is inserted into the suction introduction port 6 of the Coanda spiral flow unit 3, thus achieving an efficient rousing, line connection possibility test, and line connection.</p> |
