A plurality of embedded pipes (30A) (30B) are connected, but the overall length is equal to the longitudinal dimension equal to the facing distance between the pipe stop pipe (13) and the pipe stop plate (40) of the expansion head (10). Since it is carried by the pipe stop pipe (13) and the pipe stop plate (40) and travels in the soil, it seems that no resistance is added, but in reality, the surroundings Due to the frictional force with the earth and sand and gravel, the connecting collar (56) also causes the buried pipe (30A) (3
Since the diameter is slightly larger than 0B), even if a taper (taper angle is indicated by θ) is provided in the traveling direction, the pressing force acts backward due to the frictional force due to the earth pressure. That is, during the pulling operation, the connecting collar (56) is strongly pressed against the pipe stop plate (40), and as a result, the connecting collar (56) comes off the embedded pipes (30A) (30B), causing a gap between the pipe end faces. It often caused gaps and gaps.

1. An extension head is attached to the tip of the pilot pipe after the tip of the pilot pipe reaches the arrival vertical hole, and a traction pipe having a joining means is fixed to the rear end of the expansion head. The embedded pipe is inserted and held between the casing pipe and the pipe stop pipe provided at the rear end of the expansion head and the pipe stop plate provided at the rear end of the traction pipe, and in this state, the expansion head is piloted. The embedded pipe is propelled by pulling the tow pipe by consolidating tow through the pipe, and thereafter, the connection of the tow pipe and the buried pipe and the propulsion of the buried pipe by towing the tow pipe are alternately repeated. A buried pipe used in a traction burying method for burying a number of buried pipes between a starter vertical hole and a reaching vertical hole, wherein the length of each of the buried pipes is 1 Length and length of each book In addition to setting the dimensions, the total length of the embedded pipes when a plurality of pipes are connected is made approximately equal to the facing distance between the pipe stop pipe and the pipe stop plate, and the pipes are sequentially connected in a butt state with the preceding embedded pipe. An embedding pipe for a towing embedding method, characterized in that a collar for connecting to the rear end outer peripheral surface of the preceding embedding pipe is fixed to the outer peripheral surface of the front end of the following embedding pipe prior to the towing embedding.
