摘要： PROBLEM TO BE SOLVED: To avoid decrease in a pipe body guide force, even though performing a connection work, after a third pipe body and to reduce the amount of remaining stabilizing liquid in a laid pipe body. SOLUTION: When performing the connection for the pipe body PU2 after a third pipe body, a blocking device 10 is moved to the inside of the pipe body PU at the end in the pipe bodies for which the laying and connection have been completed, and the connection is carried out by suction via the suction pipe 12 from the relevant position.

摘要： PROBLEM TO BE SOLVED: To provide a new embedding method for a pipe body and a filler used therefor. SOLUTION: An excavated trench is filled with slurry having bentonite as main ingredients, and after the pipe body is settled, cement and calcium aluminate accelerator of hardening are added to constitute the embedding method of the pipe body for hardening the slurry, and a hardener for the slurry containing cement 100 to 400 kg and calcium aluminate accelerator of hardening 3 to 150 kg to the slurry 1 m3 used for the method is included, and accordingly, even if humus is contained in excavated soil, a speed of the execution can be accelerated.

摘要： PROBLEM TO BE SOLVED: To improve execution work efficiency. SOLUTION: A preceding pipe body 10 is immersed in an excavating groove 2 filled with a stabilizing liquid B1, a partition wall 30 is arranged in a lengthwise directional intermediate position of the preceding pipe body 10, a base end side first solidifying object area 31 of the preceding pipe body is partitioned, a tip part of the preceding pipe body 30 is positioned on the succeeding pipe body arranging side of the partition wall 30, solidification of the first solidifying object area 31 is started thereafter, and while pertforming this solidification, a process of excavating a succeeding excavating groove 2A on the succeeding pipe body 100 arranging side, an immersing process of a succeeding pipe body 100 in the succeeding excavating groove 2A, a connecting process of the succeeding pipe body 100 and the preceding pipe body 10 and a solidifying process in the succeeding excavating groove 2A are successively performed.

摘要： PROBLEM TO BE SOLVED: To hold a tube body in a specified suspension support attitude. SOLUTION: This method holds a tube body PU2 in a specified suspension support attitude in immersing the tube body PU2 suspended in an excavated groove filled with slurry B and supporting the sunk tube body PU2 suspended in the slurry B. In this case, guide bars 10A and 10B are provided in the excavated groove, on the other hand, guided tubes 23A and 23B into which these guide bars 10A and 10B are inserted and which are guided along the guide bars 10A and 10B are provided in the tube body PU2. In hanging the tube body PU2 down, the guide bars 10A and 10B are inserted into the guided tubes 23A and 23B of the tube body PU2, and while guiding the tube body PU2 along the guide bars 10A and 10B through the guided tubes 23A and 23B, the tube body PU2 is immersed in the slurry B in the excavated groove. With the tube body PU2 supported, the tube body PU2 is held in specified horizontal attitude or inclined attitude with the tube body PU2 engaged with the guide bars 10A and 10B through the guided tubes 23A and 23B.
