<p>PURPOSE: To form a continuous cable conduit at the same time as the construction work of a pipe line in the ground. CONSTITUTION: After a plurality of pipe bases 1 formed by penetrating cable conduit small holes 3 at least in the longitudinal direction are connected in the longitudinal direction, pipe lining materials 10 formed by impregnating curable resin into them are inverted to insert them into the small holes 3 with fluid pressure, and the hard resin infiltrated into the pipe lining materials 10 is solidified in a state to push them against the inside circumferential walls of the small holes 3. When a pipe line is constructed, if a plurality of pipe bases 1 are connected, a plurality of small holes 3 are linked to form a cable conduit 8 in the pipe bases 1, and since the conduit 8 is monolithically lined with the pipe lining materials 10, even if there uneven steps in joint sections of the pipe bases 1 thereafter, the pipe lining materials 10 are deformed in accordance with the uneven steps to ensure the continuous cable conduit 8. For that pourpose, disconnection of the cable passing through the cable conduit 8 is prevented. The cable conduit 8 is formed at the same time as the construction work of the pipe line in the ground.</p> |
