LEADING END PROPULSION PIPE AND A CONSTRUCTION METHOD THEREOF, CAPABLE OF EASILY PROGRESSING A PROPULSION OPERATION BY DISCHARGING THE SOIL, GROUND STONES TO OUTSIDE AND NEARLY SEALING THE INSIDE OF A PIPE

摘要

PURPOSE: A leading end propulsion pipe and a construction method thereof are provided to easily install by improving a structure of a leading end propulsion pipe to bury a pipe etc. and to prevent soil or stone or water etc. from flowing into inside.;CONSTITUTION: A leading end propulsion pipe comprises a pipe body(10), one or more tubes(30), a driving unit, and a forced feed unit(50). The pipe is formed into a circular or a polygonal shape. The one or more pipes are mounted by a fixing member(20) at constant intervals in the whole or a part of inner surface area of the leading end pipe. The driving unit inflates the tube by injecting into compressed air or fluid or constringes by discharging the compressed air or fluid inside the tube to outside. The forced feed unit is supported between the tubes and connected to a feed pipe and compulsorily discharges the soil, stone, or water to outside.;COPYRIGHT KIPO 2012
