A connecting flange 7 is arranged at the lower end of the pressurized return slurry port device 6. The pressurized return slurry port device 6 is connected to the upper end of the conduit 4 through the connecting flange 7; the pressurized return slurry port device 6 includes a slurry outlet 8 and a high-pressure air duct inlet 9. The slurry outlet 8 is arranged on the side wall of the pressurized slurry outlet 8 device 6, and the high-pressure air duct inlet 9 is arranged at the upper end of the pressurized slurry outlet 8 device 6.

[0024] The longitudinal beam 2 is provided with limited fixing holes 1, and the limited fixing holes 1 are arranged in a plurality of groups.

[0025] The cross section of the through hole is set to a circular structure, or the cross section of the through hole is set to a rectangular structure, which can be set according to actual needs.

[0026] The cross beams 3 are arranged in two groups, and the two groups of cross beams 3 are arranged in parallel. The two groups of cross beams 3 are located on the left and right sides of the conduit 4. The lower ends of the columns 10 are vertically arranged on the longitudinal beams 2, and the lower ends of the columns 10 are fixedly welded to the longitudinal beams 2.

[0027] The utility model comprises the following steps during use:

[0028] Assemble the longitudinal beams 2 and cross beams 3 of the base together, ensure that the two sets of longitudinal beams 2 are arranged in parallel, and the cross beams 3 connect the longitudinal beams 2 to form a stable support structure;

[0029] Four groups of columns 10 are vertically welded on the longitudinal beam 2 of the base, and the upper ends of the columns 10 are connected by steel plates 5 to form a rectangular space to support the conduit 4;
