    摘要： A pipe joint assembly comprises a ring-like insert disposed on the spigot of one pipe section and a ring-like insert disposed in the socket of an adjacent pipe section. The inserts include ribs for inhibiting the accumulation of material within grooved portions of the inserts during fabrication of the pipe sections, and for resisting the leakage of fluid between the inserts and the pipe section. A gasket is disposed within the grooved portions of the inserts to couple and seal the pipe sections. The gasket is uniquely configured to provide maximum sealing, and includes shoulder portions which enhance sealing, as well as maintain the gasket in position during interengagement of the pipe sections.

    摘要： A precast unit, preferably of cementitious material, of circular outline having stone-like block units on the outer surface separated by mortar joints and top shoulder annular portions to serve as a guide to enable stacking like units above each other. The inner surface of each unit and outer surface of each projection extend in a downwardly and outwardly extending direction to provide a stepped inner wall.

    摘要： A concrete pipe for laying in bend of a pipe line. The pipe is of straight cylindrical, spigot and socket type. The socket is deliberately splayed so that socket axis is inclined at acute angle to longitudinal pipe axis to enable strong joint between successive pipes laid at angle to one another.

    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： Non-metallic, disposable rings are employed in the forming of a groove in the spigot portion of concrete pipe sections. This disposable ring is attached to either the header or the pallet section of a pipe-making form in proper position to form the desired groove in the spigot portion of the concrete pipe section during the making of the concrete pipe section. The ring is made of any rigid, non-metallic disposable material capable of resisting heat, water, alkali and steam. The disposable ring may be left in place when the header and pallet sections of the form are removed from the partially cured pipe. The ring may be removed from the pipe section some time after the pipe section has properly cured, preferably at the time the pipe section is to be used. The possibility of damage to the groove may thus be reduced or eliminated, and the groove may be kept free of dirt and other foreign matter until the pipe section is actually employed during the installation of a line of concrete pipe.

    摘要翻译： 非金属，一次性环用于在混凝土管段的插口部分中形成槽。 该一次性环在制管形成部件的集管或托板部分的适当位置附接，以在混凝土管段制造期间在混凝土管段的插口部分中形成所需的槽。 该环由能够抵抗热，水，碱和蒸汽的任何刚性，非金属的一次性材料制成。 当形状的集管和托板部分从部分固化的管中移除时，一次性环可以留在原处。 在管段已经适当固化之后，优选地在管段被使用时，环可以在管段中被去除。 因此，可以减少或消除对凹槽的损坏的可能性，并且在安装一条混凝土管道期间，直到实际使用管段之前，沟槽可以保持没有污物和其它异物。
