Method and device for the monolithic production of concrete conduits and pipes, particularly of the continuous type

摘要

a. Method and device for the monolithic production of pipes and conduits. b. Method and device characterised in that well-defined concrete is placed in the free space existing between the outer formwork 1 and the inner formwork 7 of the corresponding device, under a pressure suited to the setting of this concrete per unit of time and via a filling funnel 21, after which, while the concrete is moving towards a pressure plate 19, a vacuum pump 16 is connected, after the operation of which, after a period of time defined for the start of the setting of the concrete, the bolt 25 is unlocked, causing the device according to the invention, which is located on the concrete base 4, to slide along this concrete base, at a speed corresponding to the advance of the concrete per unit of time in the device, from which the finished pipe emerges, in a continuous manner, with a strength allowing the formwork to be removed. c. The invention may be applied to the continuous production of concrete conduits on site. <IMAGE>
