The invention discloses a rapid casing
pipe type well digging device. The device comprises a support, a soil
auger, an oil taking
barrel, a small water pump, a water injection
pipe, a casing
pipe, a
water seepage pipe and a
silt sucking
water pipe or a water sucking pipe. A rapid casing pipe well digging method comprises the steps that in a dry and sandy area sandy land or a windy desert area or a sandy land, the soil taking
barrel is used for
punching a hole in a phreatic layer, a
pulley hook of the support is aligned to the center of a well hole and hooks the upper end of the casing pipe, the casing pipe is placed into the well hole, the soil
auger is used for drilling and taking
silt in the casing pipe or the
silt sucking
water pipe and the water injection pipe are inserted to the bottom of the casing pipe for sucking silt, the casing pipe gradually descends along with taking-out of the silt, a
pulley hook
rope of the support is used for pulling the top of the casing pipe to descend until reaching the place nearby the underground water line, the
water seepage pipe is inserted into the bottom of the casing pipe, then a
pulley of the support is used for lifting out the casing pipe, the
water seepage pipe deeply penetrates into the underground water containing layer, the water sucking pipe is inserted into the internal area of the water seepage pipe, the upper portion of the water sucking pipe is fixedly connected with the small water pump, and
rapid casting pipe type well digging work is completed.
