ABSTRACT:
A method for joining of pipes, especially large concrete pipes, heretofore been a comparatively cumbersome procedure necessitating the use of special tools by means of which a pressure has been exerted on the back end of the pipe to push it towards the last of the previously laid pipes. In order to simplify the laying and joining of the pipes, it is proposed wherein a pipe (1) which is to be joined to the last laid pipe (2) in the pipe line (3) is placed in alignment in front of the end of the last laid pipe (2), an asymmetrical two-legged lifting strap (10,11) is used, the shorter leg (10) of which is attached to pipe (1), which is to be joined to the last laid pipe (2) in the pipe line (3), at the end portion which is nearest to the joining end, the longer leg (11) of the lifting strap is attached to one of the previously laid pipes (2) of the pipe line (3), and to the point of connection (7) between the legs (10,11) there is connected a hoisting device (15) by means of which a slight vertical heave is effected, resulting in the pipe (1) being pulled in the direction towards the last laid pipe. The invention also includes the lifting strap capable of carrying out the pulling operation.
