Abstract
The invention relates to the formation of ground areas consisting of a three-dimensional mixture of textile threads and a granular material. According to the invention, the portable machine provided for this purpose comprises a tube provided with a handle and ending in a head equipped with ejectors, each of which has an ejection nozzle fed with threads and receiving a supply of pressurized fluid intended to spray the threads onto the ground area, said ejectors being disposed on a distributor bar on which they are oscillatably mounted. Means may in addition be provided to control the frequency and the oscillation amplitude of the ejectors and also the ejection speed of the threads. The invention is applicable to the construction of reinforced ground structures.

Portable machine intended for spraying textile threads, in particular for constructing reinforced ground areas consisting of a three-dimensional mixture of such threads suitably entangled in the mixture and of a granular material delivered onto the area of ground in an accelerated jet with the aid of separate supply means, said machine being characterized in that it comprises a tube provided with a handle and ending in a head equipped with ejectors each of which has an ejection nozzle fed with threads and receiving a supply of pressurized fluid intended to spray the threads out of the nozzles towards the area of ground being formed, said ejectors being disposed on at least one distributor row with oscillating mounting.
Process for the construction of reinforced ground structure consisting of a three-dimensional mixture of a granular mixture and of textile threads by means of a machine comprising ejector means for ejecting from the machine the textile threads and supply means for delivering onto the area of ground the granular material in an accelerated jet, characterized in that while delivering a defined quantity of granular material onto a zone of ground of determined width which it is desired to reinforce, a reciprocating oscillatory movement is imparted to the ejectors in such a manner as to sweep over the entire required width of ground with an adjustment such that the jets of threads are superposed in pairs.
