Abstract
Esta invención se refiere a un aparato para revestir la superficie externa de un cuerpo alargado (10), tal como una varilla o un tubo, con una capa de concreto (30), que comprende una estructura de armazón (21). Se pueden suministrar secciones de tubo o tubería (10) a un dispositivo inclinador (27) en una posición horizontal sobre un soporte móvil (12) y ser inclinadas hasta una posición vertical dentro de la estructura de armazón semejante a una torre (21). El aparato comprende medios (24, 27) para retener el cuerpo alargado (10) en la posición vertical dentro de la estructura de armazón y un molde anular (26) para rodear el cuerpo alargado vertical para definir un espacio anular entre el cuerpo alargado y el molde anular, y el concreto puede ser alimentado al espacio del molde anular por los medios de alimentación (28, 29). El molde puede comprender una parte semejante a un embudo, superior, la cual es giratoria alrededor del eje del molde anular con relación a la parte restante del molde, para distribuir la mezcla de concreto periféricamente en el espacio del molde anular. La capa de concreto moldeada puede ser expuesta al vacío por medio de una cámara de vacío semejante a un faldón o campana, por lo cual el agua libre puede ser extraída de la capa de concreto.This invention relates to an apparatus for coating the external surface of an elongated body (10), such as a rod or tube, with a layer of concrete (30), comprising a frame structure (21). Tube or pipe sections (10) can be supplied to a tilting device (27) in a horizontal position on a movable support (12) and tilted to a vertical position within the tower-like frame structure (21). The apparatus comprises means (24, 27) for retaining the elongated body (10) in the vertical position within the frame structure and an annular mold (26) for surrounding the vertical elongated body to define an annular space between the elongated body and the annular mold, and the concrete can be fed into the annular mold space by the feeding means (28, 29). The mold may comprise an upper, funnel-like part, which is rotatable about the axis of the annular mold relative to the remaining part of the mold, to distribute the concrete mixture peripherally in the annular mold space. The molded concrete layer can be exposed to vacuum by means of a vacuum chamber similar to a skirt or bell, whereby free water can be extracted from the concrete layer.
