Soil body drying treatment device and soil body drying treatment method

Abstract

The invention discloses a soil drying treatment device. The device comprises a cylindrical tank body, wherein the cylindrical tank body is provided with an inner interlayer, the inner side wall of theinner interlayer is provided with water permeable holes, the side face of the inner interlayer is connected with a pumping and discharging device, a spiral stirring column is arranged in a cylindrical inner cavity, an inner pumping and discharging cavity is formed in the body of the column, water permeable holes are formed in the outer side wall of the inner pumping and discharging cavity, an inner pumping and discharging pipe extends into the inner pumping and discharging cavity and is connected with an external pumping and discharging device, and a rotation driving mechanism is arranged atthe upper end of the spiral stirring column. The invention further provides a soil body drying treatment method implemented by adopting the device. According to the device and the method, water entering a soil body in the cylindrical tank body can be rapidly pumped and drained; particularly, the soil body is gradually pumped, drained and dried in the process of being conveyed downwards by spiral stirring blades; the soil body is turned over in the conveying process, so the soil body is comprehensively contacted with the water permeable holes in the inner side of the inner interlayer and the water permeable holes in the outer side wall of the inner pumping and draining cavity and is comprehensively pumped and drained; and the soil body discharged from a lower end is comprehensively dried.

Description

technical field [0001] The invention relates to a soil drying treatment device. The present invention also relates to a soil drying treatment method implemented by using the above soil drying treatment device. Background technique [0002] The traditional vacuum preloading and drainage system belongs to the technical field of soft soil foundation treatment and includes a horizontal drainage pipe, a connecting hose and a drainage board; the two ends of the connecting hose run through the horizontal drainage pipe and are respectively sealed and connected to the drainage board; The joint of the connecting hose and the horizontal drain pipe is sealed; the connecting hose inside the horizontal drain pipe is provided with a vacuum transmission hole; the horizontal drain pipe is connected with the transfer pipe. The invention also discloses a vacuum preloading method, which includes the following steps: setting the drainage plate wrapped with the waterproof geotextile into the sof...
