Summary:PURPOSE:To lessen the rate of road occupancy under construction by excavating a hole with a broad depth through a slit formed on the surface pavement, inserting a tubing flatly reformed and filling the fillers into its peripheral part after reforming the flat section into a circular section. CONSTITUTION:A slitlike opening 2 is formed by slitting the surface pavement 1 in the direction of buried tube. Then, a ground exposed to the slitlike opening 2 is excavated for a hole 3 with a broad depth for tube arrangement by means of an excavator 13 of high pressure jet system and an earth exhaust equipment 14 of vacuum system. After inserting the tubing flatly reformed into an oval section into the hole 3, it is reformed into a circular section by pressing pressure liquid into the tubing. And the fillers such as cement bentonite etc., are filled into a gap of the periphery of the tubing buried into the hole 3 to fill it.
