摘要： Conduit sections are disclosed for forming pipe lines. Sections have preformed core members of variable shapes and wall thicknesses and cast-in-place concrete components formed selectively on external surfaces and bonded to the core by mechanical and/or chemical means, thereby forming an integral structure. The chemical bonding utilizes adhesives and the like to secure the outer component on core surfaces while the mechanical bonding may utilize various structural shapes to secure the outer component to the inner core. A narrow trenchlike form in selected contours and dimensions may be utilized as a side and bottom forming member into which concrete or other plastic mix is placed before it is cured. Preferably only slight clearance is provided between the core and the trench sides to allow placement and consolidation of the concrete mix. Components of variable thicknesses may be so formed, thereby providing greatest strength in areas where maximum support of the load is required.

摘要： An apparatus and method are disclosed for installing preformed pipe sections or for manufacturing in place composite pipelines and reinforced and non-reinforced cast in place pipelines. The apparatus includes means for handling the components which consist of rigid pipe sections, cores or forms and flowable backpacking material such as soil, soil-cement or concrete. The apparatus serves as a protective shield and may be selfpropelled. It has optional means of articulation; of lateral and vertical guidance; of installing variable walled core components and of adjusting hopper components to place backfill material on either or both sides or around inner components. Methods are disclosed for manufacturing and installing such pipelines in either narrow or wide trenches or on flat surfaces and of forming all of these pipelines in a continuous, semi-automated fashion. The apparatus includes receptacle and backpacking portions in combination to receive and position the inner pipe sections or core forms and to distribute and trowel flowable backpackingballasting material on the sides, bottom and/or top of the inner units as the apparatus is propelled by reaction of rams against these inner units.
