    • A buried conduit consisting, in transverse cross-section, of a lower component (2) and a covering upper component (1) which bears on the upper part of the side walls (22) of the lower component (2) by means of lengthwise bearing members (3). According to the invention, the upper component (1) forms an arched vault made so as to have sufficient flexibility to distort slightly under the effect of the forces to which it is subjected, and the lower component (2) is made so as to resist, without distortion, the forces transmitted by the ground and by the upper component (1), both components being fixed to each other along the lengthwise bearing members (3) and the latter consisting of socket joints, so as to permit the bearing parts of the distortable upper component to pivot without sliding relative to the undistortable lower component.

    • A hollow body assembly wherein a circumferential flange is disposed on the outside and/or inside of each of a pair of individual elements to be connected at their connecting surfaces. Each of the flanges has a transverse outer surface which is perpendicular to the longitudinal axis of its respective individual element and an inner surface which is oblique to the transverse direction of the outer surface. A circumferential ring having an inner channel surrounds the flanges when the elements are connected, the ring having side edges for gripping the oblique surfaces of the flanges. The distance between the side edges of the ring when it is in its unstressed condition is less than the distance between the base points of the oblique surfaces of the flanges.
    • 一种中空体组件,其中周向凸缘设置在要连接在其连接表面上的一对单独元件的外侧和/或内侧。 每个凸缘具有垂直于其相应单独元件的纵向轴线的横向外表面和与外表面的横向方向倾斜的内表面。 当元件连接时,具有内部通道的圆周环围绕凸缘,该环具有用于夹紧凸缘的倾斜表面的侧边缘。 当环处于其不受应力状态时,环的侧边缘之间的距离小于凸缘的倾斜表面的基点之间的距离。

    • A shaft liner assembly has a series of layers of arcuate segments, the segments in each layer forming a circle, and each side edge portion of each segment being outwardly reversely bent. A series of connecting brackets each have a longitudinally-extending base portion with wing portions extending from opposite sides thereof and inclined towards one another, each bracket being in sliding engagement with adjacent reversely bent portions of respective laterally adjacent segments in two vertically adjacent layers of segments. The wing portions of each connecting bracket are on the opposite side of the respective reversely bent portions of the segments to the base portion to secure laterally and verticaly adjacent segments together.
    • 轴衬组件具有一系列弧形段,各层中的段形成一个圆,并且每个段的每个侧边缘部分向外反向弯曲。 一系列连接支架各自具有纵向延伸的基部,其翼部从相对侧延伸并且彼此相对倾斜,每个托架与相邻横向相邻的段的相邻的反向弯曲部分滑动接合在两个垂直相邻的段 。 每个连接托架的翼部位于相应的部分的相反的弯曲部分的相对侧到基部,以将横向和垂直的相邻段固定在一起。
