The sand cleaning method of the sand cleaning system of the steel pipe pile side slurry pressing groove according to claim 8, characterized in that: the sand cleaning system (1000) further comprises a sand cleaning platform (14), a simple support (5) and a rope winder (9) are arranged above the sand cleaning platform (14), a fixed pulley (7) is arranged at the top of the simple support (5), and a steel wire rope (6) of the rope winder (9) is connected with and lifts the sand cleaning pipe assembly (101) through the fixed pulley (7); a plurality of arc-shaped guide ribs (42) are circumferentially arranged on the steel pipe part of the sand suction pipe (1), one end of the steel wire rope (6) is connected with the rope winder (9), and the other end of the steel wire rope is connected and fixed on the guide ribs (42);
after the sand cleaning system starts to work, the rope winder (9) starts to slowly lower the sand cleaning pipe assembly (101), so that the bottom opening of the sand suction pipe (1) starts to be lowered at a speed of 15cm/min from two meters away from the sand surface of the pile side mortar pressing groove (200) until the sand suction pipe (1) discharges clear water, and the sand cleaning work is finished.
10. The sand cleaning method of the sand cleaning system of the steel pipe pile side slurry pressing groove according to claim 9, characterized in that: one end of the water injection pipe (2) positioned outside the heightening steel pipe (8) is connected with a pulp press (10), and one end of the air pipe (3) positioned outside the heightening steel pipe (8) is sequentially connected with an air storage tank (12) and an air compressor (13);
when the water injection pipe (2) is needed to inject high-pressure water to the steel pipe (8), the grouting machine (10) is started; when the air pipe (3) is required to convey high-pressure air into the height-connecting steel pipe (8), the air compressor (13) is started.
