    • 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.
    • 目的:提供一种前端推进管及其施工方法,通过改进前端推进管的结构以便埋设管等,并且防止土壤或石头或水等流入内部而容易地安装。 构成:前端推进管包括管体(10),一个或多个管(30),驱动单元和强制进给单元(50)。 管形成为圆形或多边形。 一个或多个管道由固定构件(20)以一定间隔安装在前端管的内表面区域的整个或一部分中。 驱动单元通过将压缩空气或管内的压缩空气或流体排出到外部而将压缩空气或流体注入或收缩来使管膨胀。 强制进料单元支撑在管之间并连接到进料管,并强制将土壤,石头或水排放到外部。
