[0028] The present invention will be further explained below in conjunction with the drawings in the specification:
[0029] The principle of the present invention is an earthwork construction method that uses water flow to dig and transport soil, that is, water flows through a high-pressure water pump and is pressurized and sprayed out through a water gun to form a dense high-speed water column, which cuts and crushes the soil to make it It is humidified and disintegrated to form a mixture of mud and mud, and then transported to the spoil area by the mud pump and mud pipe, and settled in the spoil area, and the clear water after precipitation is discharged or recycled.
[0030] The construction process of the present invention is: foundation pit support and division-excavation of mud suction tank-installation of mud pump-installation of high-pressure water pump and water supply tank-excavation of spoil area-installation of mud pipe and intermediate pressurization equipment-water fl...
