Abstract
La presente invenzione riguarda un perfezionamento in un metodo per guidare uno scudo meccanico. Una soluzione contenente un agente schiumogeno diluito con acqua ed immagazzinato in un serbatoio viene agitato da un generatore di schiuma assieme con aria alimentata da un compressore per generare schiuma. La schiuma così prodotta viene alimentata tramite un tubo ad una superficie di scavo e/o una camera di pressione del terreno della macchina a scudo meccanico. La resistenza di attrito fra la testa di taglio e la superficie di scavo viene ridotta per effetto dell'azione lubrificante della schiuma. Lo sterro portato nella camera di pressione del terreno e la schiuma vengono agitati e mescolati assieme per formare sterro contenente bolle di aria ed avente maggiore fluidità e minore permeabilità. Lo scavo alla superficie di taglio si effettua mentre si contrasta la pressione del terreno e la pressione dell'acqua nel terreno con lo sterro contenente le bolle di aria, e contemporaneamente lo sterro viene scaricato dalla camera di pressione del terreno mediante un trasportatore a coclea.The present invention relates to an improvement in a method for guiding a mechanical shield. A solution containing a foaming agent diluted with water and stored in a tank is stirred by a foam generator together with air supplied by a compressor to generate foam. The foam thus produced is fed through a tube to an excavation surface and / or a soil pressure chamber of the mechanical shield machine. The frictional resistance between the cutting head and the excavation surface is reduced due to the lubricating action of the foam. The earthwork brought into the soil pressure chamber and the foam are stirred and mixed together to form earthwork containing air bubbles and having greater fluidity and less permeability. The excavation to the cutting surface is carried out while the pressure of the soil and the pressure of the water in the soil are contrasted with the cut containing the air bubbles, and at the same time the cut is discharged from the pressure chamber of the soil by means of an auger conveyor.
