Date Aug. 10, 1995There are provided a pipe (9) having a slit (6) along a longitudinal direction thereof throughout a full length thereof, a moving body (23) inserted into the pipe (9) and being movable in the pipe (9) by means of a compressed air fed into the pipe (9), and a connection member (1) comprising a wire, connected to the moving body (23) in the pipe (9) at a base end thereof, passing through the slit (6) and positioned outside the pipe (9) at a leading end thereof to which a material (15) to be laid or an object is connected. It is preferable that a sealing wire rod (8) which can blockade the slit (6) is arranged in the pipe (9) throughout the full length of the pipe, and that a guide groove (7) for guiding the sealing wire rod (8) so as to blockade the slit (6) at the time of movement of the moving body (23) is disposed on the moving body (23). The smaller number of persons can ensure the laying or transporting operation, and can reduce the laying or transporting time sharply compared with that in the prior art apparatuses. Also, the operator can be efficiently and safely ensured even if the course is located at the elevated spot and the complicated place.
