The simple methods of drilling sand pumping include suction, Hank suction and jet flow, a total of three.
The suction type mainly refers to the use of high pressure pump to suck up, and the Hank suction type pumps the sand from underwater through the negative pressure generated in the engine room. The jet stream draws sand in and shoots it up with water.
The vertical sand pumping pump can be combined with the high pressure clean water pump to form a hydraulic digging and filling unit for dredging and blowing, and several vertical pumps can be combined in series with the horizontal ship-land dual-purpose mud pumps to form a pump group.
Hydraulic sand dredging, soil dredging and filling units carry out hydraulic mechanization construction, which simulates the principle of natural water flow washing, and uses hydraulic power to dredge and dredge. The high-pressure water pump produces pressure, and the high-pressure and high-speed water column is shot out through the high-pressure water jet. The water column impacts the soil and sand, so that the soil and sand are humidified, disintegrated and mixed into a mixture of mud and mud, which is then lifted by the vertical mud pump. It's piped to the battlefield.
The simplest way to dig a well with sand is: if it is pure sand layer, and the water level is shallow, you can dig a well manually, use a cement prefabricated pipe to make the wall, the size can be determined according to your own requirements, with a diameter of one meter to two meters, people dig in the pipe, the pipe can automatically sink, sink a section, and pile a section on the ground, so that the well Bob is large and contains more water, which can be used to pour the ground.
