    • The manufacture of extended, inaccessible holes for underground ducts, conduits and the like is performed by a closed construction process, wherein the preferably remotely-controlled excavation is performed and following that a structure is installed which is employed as the product duct, conduit or the like. The installed structure is provided by injection of an injection material under pressure into an annular space between a form following the excavating apparatus and the ground to manufacture at least one endless inner wall for the hole which then serves as the underground duct, conduit or the like. The novel apparatus of this invention correspondingly comprises a form following the required excavation mechanism conformed to form an annular space between the form and the ground, that form having a form front closing the form and at least one inlet therein for injection of an injection material into the annular space.
    • 用于地下管道,管道等的延伸的,不可接近的孔的制造通过封闭的构造过程进行,其中优选地进行远程控制的挖掘,并且随后安装用作产品管道,导管或 喜欢。 通过将注射材料在压力下注入到挖掘装置之后的形式和地面之间的环形空间中来提供安装的结构,以制造用于孔的至少一个环形内壁,然后用作地下管道,管道等 。 本发明的新型装置相应地包括一种遵循所要求的挖掘机构的形式,其符合形式和地面之间的环形空间,该形式具有封闭形式的形式前端以及用于将注入材料注入的至少一个入口 环形空间。
