Abstract (en)
[origin: WO2014199337A1] A system for feeding consolidating mixture for multiple inlet sleeve pipes used for the consolidation grouting of loose ground comprising a computerised distributor valve having an inlet connection connected to a grout pumping system and a plurality of outlet connections capable of delivering cementitious grout to each of the individual inlet pipes of the multiple inlet sleeve pipe connected hydraulically thereto. Each outlet connection has a servo- valve, a pressure measuring device and a flow measuring device connected to a process controller capable of carrying out any desired feed sequence to each individual pipe present in the sleeve pipe, monitoring the pressure and volume of mixture injected.
