<p>PURPOSE:To facilitate laying of cable by adhering a cable to the inner wall of a conduit then adhering a tube to the inner wall of the conduit, thereby supporting and securing the cable. CONSTITUTION:An optical cable 3 is temporarily secured through adhesive 4 to the inner wall at the upper section of a conduit 2. Then a folded tube 1 is penetrated into the conduit 2. The terminal of the tube 1 inserted into the conduit 2 are closed, then compressed air is ejected to the inside of the tube from the inlet side. The compressed air is mixed with epoxy adhesive in the shape of spray. The adhesive is applied entirely onto the inner wall of the conduit 2 through fine holes made through the tube 1, thus adhering the tube 1 to the inner wall while simultaneously clogging the pits of the tube 1 and coating the inner face.</p> |
