Abstract: Disclosed is a pumping method of a large-diameter horizontal pressurized long dewatering well for inexhaustible pumping strata. Clay layers and sand soil layers are determined according to construction positions of foundation pits, horizontal holes are drilled in the sand soil layers with a drill rig with simultaneous casing, and after the designed depth is reached, horizontal wells are placed, the horizontal wells are located above the junction of the clay layers and the sand soil layers, and the horizontal wells comprise drain pipes and air ducts, the drain pipes and the air ducts are located at the same elevation, each air duct is located between the two drain pipes, and the air duct is connected with the air pipe of the air compressor to deliver and pressurize, so as to facilitate water in the strata of aquifer to gather into the drain pipes.

Abstract: A microwave hood system is provided. The microwave hood system includes a microwave oven enclosure defining a cooking cavity therein. A cooking component is positioned within the cooking cavity and configured to emit microwaves. The heating system defines a heating cavity therein, wherein the heating system is coupled to the microwave oven enclosure. A heating element is positioned in the heating cavity. The heating cavity reaches a temperature in a range from about 40° C. to about 80° C. when the heating element is in use. A broiler element is positioned within the heating cavity. The heating cavity reaches a temperature in a range from about hundred and 150° C. to about 300° C. when the broiler element is in use. A dual hood system is also coupled to the microwave hood system.

Abstract: Disclosed are a construction method and a construction system for eliminating sand liquefaction. The construction system includes a first drilling rod, a pneumatic down-the-hole (DTH) hammer installed on the first drilling rod, an air compressor drivingly connected with the pneumatic DTH hammer, a driving motor drivingly connected with the first drilling rod and a high-pressure pump connected with the first drilling rod; and the construction method includes following steps: measuring the ground to be constructed to determine the pile position to be constructed; controlling the air compressor to drive the pneumatic DTH hammer to drill holes in the pile position to be constructed, controlling the driving motor to drive the first drilling rod to rotate around an axis in an up-down direction, and controlling the high-pressure pump to spray the cement slurry toward a circumferential side of the first drilling rod.
