Abstract
A gravity fed slurry delivery system capable of pumping high volumes of abrasive slurry at a worksite. A single operator mobile abrasive slurry delivery apparatus of the present invention may be used to pump an abrasive grout slurry at high volumes or pressure to lift concrete slabs, to fill voids under concrete slabs, to deliver abrasive grout for compaction grouting, or to deliver abrasive grout for construction joint stabilization.
Claims20
A mobile abrasive slurry delivery apparatus, the apparatus comprising:
- a base frame;
- a hopper frame rotationally coupled to the base frame;
- a hopper having a bottom section, sidewalls, a front end wall and a rear end wall, wherein the sidewalls, the front end wall and the rear end wall extend upward from the bottom section, and wherein the bottom section includes a main segment and a secondary segment such that the secondary segment extends upward at an angle less than ninety degrees from a plane of the main segment, and further wherein the secondary segment has a slurry outlet opening formed in the secondary segment;
- a slurry tube coupled to the hopper in a sealing alignment with the slurry outlet opening of the secondary segment;
- an abrasive slurry pump mounted to the hopper and aligned with the slurry outlet opening of the secondary segment wherein a free end of the abrasive slurry pump extends into the slurry tube;
- and
- hydraulic lift cylinders, each hydraulic lift cylinder having a first end coupled to the base frame and a second end coupled to the hopper frame.
