Abstract

The process involves the sucking up of broken up, excavated material into a pivotable bin (7). Breaking up may be effected pneumatically by a compressed air lance (25-27), and vacuum by a an air pump (1) giving negative pressures of 250-300mb with an air flow of 1500 to 2000Nm power 3 h. Alternatively the soil may be broken up by a pneumatic drill, the conduit (4) being supported by a cantilever boom (11,42). A lorry (20) may locate a compressor (10), pump (1) and bin (7), with the pump drive (41) taken from the prop-shaft (23). An air pipe (29,30) connects the pump to the bin and includes a filter (8) and a demountable coupling (9).
