    Abstract: A method of moulding articles from a concrete mixture. As shown in Fig 1, the water (12) is first poured into the mould (14, 14'), whereafter the dry cement mixture (2) is poured into the mould, soaking up the water. Another form of the invention is shown in Fig 2, where instead of pouring the water into the mould, the cement mixture (2) is moistened by water (1) sprayed into the dry mixture just before the mixture is poured into the mould. The invention is especially advantageous when mixtures containing fibres are used or when the articles are formed by centrifugal moulding.

    Abstract: The invention relates to an installation for producing pipe elements by centrifugal casting, characterized in that it comprises a feed device (6) and modules (1 to 5). Each module comprises a rotationally mounted centrifugal casting mould (11 to 15) with drive mechanism (24, 25), heating and cooling units, sensors for monitoring speed and temperature and easily detachable connections for energy supply and control. Each module is provided with one or more elements (27) which can be engaged by a lifting device and is configured such that it can be lifted as a single piece and transported once all the connections have been released.

    Abstract: A method and an apparatus for placing ready-mixed concrete in a cylindrical form to fabricate an ultra-long and large-diametered hollow concrete cylinder by utilizing centrifugal force. It has been heretofore requested but difficult to employ stiff-consistency ready-mixed concrete for said purpose so as to increase the strength of the concrete product. In order to eliminate such a disadvantage, there are employed in the apparatus a float horizontally movable in a lengthwise direction in a cylindrical form, a vibrator provided on the float, and concrete inlet ports provided at a prescribed interval in the lengthwise direction on the cylindrical form. The method includes the steps of sequentially injecting stiff-consistency ready-mixed concrete through the concrete inlet ports and telescopically moving the float in the lengthwise direction while vibrating it, thereby filling the ready-mixed concrete in the cylindrical form to form a predetermined hollow space therein and thereafter making preparations to rotatably solidify the concrete. This makes it possible to rotatably solidify a long concrete article, which heretofore could not easily be produced by employing stiff-consistency ready-mixed concrete, and to obtain a high strength hollow concrete cylinder to be employed as a supporting leg for a submarine structure or the like.

    Abstract translation: 一种用于将预拌混凝土置于圆柱形状中的方法和装置,以通过利用离心力制造超长和大直径的空心混凝土圆筒。 迄今为止,为了提高混凝土制品的强度,迄今为止要求但难以采用硬质混凝土预拌混凝土。 为了消除这样的缺点,在装置中采用在圆筒形状的长度方向上可水平移动的浮子,设置在浮子上的振动器和在长度方向上以规定间隔设置在圆筒形上的混凝土入口 形成。 该方法包括以下步骤:通过混凝土入口连续注入硬质混凝土预拌混凝土,同时使浮体在长度方向上伸缩移动,同时振动,从而将预混混凝土填充成圆柱形,形成预定的中空空间 然后进行制备以使混凝土可旋转地固化。 这使得可以可旋转地固化长期的混凝土制品,该混凝土制品迄今为止通过使用硬质混凝土预拌混凝土不容易制造,并且获得用作海底结构的支撑腿的高强度空心混凝土柱筒,或 类似。
