<P>PROBLEM TO BE SOLVED: To early develop and provide a laying barge traction apparatus, which is superior in safety, workability, maintainability and economic efficiency and capable of doing rapid, smooth and precise traction work and moving work for a laying barge at a land reclamation and drainage work site of a soft ground with a narrow road surface in width at an apex of dam body as well as a traction method of the laying barge. <P>SOLUTION: A laying barge traction apparatus is characterized by: being installed using a weight of a dam body itself as a reactive force and also capable of laterally moving; being installed so that the apparatus mechanically has a reactive force to a slop face part of the dam body without increasing a weight of the laying barge traction apparatus itself or utilizing grounding friction against a land base; utilizing a slop face shape of the dam body to use the weight of the dam body itself as a reactive force. <P>COPYRIGHT: (C)2012,JPO&INPIT |
