ABSTRACT:
The disclosure relates to an apparatus for injecting slurry/liquid into the ground comprising a chassis (11, 12), a plurality of injectors (39) mounted on the chassis for penetrating and delivering slurry into the ground and means (55) mounted on the chassis for feeding the ground injectors from a slurry supply. The feeding means comprises an annular chamber (60) having an axially positioned inlet (68) and a plurality of outlets (62) spaced around the chamber axis and connected to the respective ground injectors (39) and a diametrically extending rotary distribution valve (86) in the chamber having a throughway in communication with the inlet and an outlet orifices (90) which sweep over the chamber outlets with rotation of the valve to deliver a quantity of slurry to each outlet. The outlet orifices of the valve are diamond-shaped to co-operate with the edges of the outlets from the chamber being formed to shear through any solid material passing between the orifice and an outlet as the orifices move past the outlets to chop up such material prior to passing to said injectors.
