Description

Sand pumping equipment and method for realizing deep hole bottom sand pumping Technical Field The invention relates to the field of sand pumping equipment, in particular to sand pumping equipment and a sand pumping method for realizing deep hole bottom sand pumping. Background When carrying out sand pumping operation, silt often deposits at the bottom, forms the hardening easily, generally needs to break up the silt of deposit, and the reuse pump of pumping is taken out, when carrying out sand pumping in a large scale, need frequent repetition to carry out above-mentioned operation alternately, and is wasted time and energy, and sand pumping inefficiency. The existing sand pumping equipment often adopts a motor to pump sand, and because the silt scene all has water, the motor can only be placed on the ground to pump sand, and cannot deeply pump sand deep underground, so that the sand pumping efficiency is lower.
