PROCESS FOR CONSTRUCTING LINEAR CONCRETE WORKS WITH INTERNAL CAVITIES, AND DEVICES FOR IMPLEMENTING SUCH PROCESS

摘要

The process comprises using a slip-form in order to shape the internal cavities, injecting a fluid, preferably wet hot air inside the sealed cavity or cavities created by said slip-form, at appropriate rate and pressure, and performing the required operation in order to conform the concrete. The device comprises said slip-form consisting of a plurality of tubes coupled to the concrete casting machine, and also provided with antivibration mechanism, the vibrating means of said machine being arranged parallel to the axes of the tubes and in lines intermediate to said tubes, means being provided to supply said fluid inside the slip-form or directly into the cavities. The invention applies to the construction of roads or collectors with internal cavities. <IMAGE>
