Soil taking device and soil taking method of starting side opening of movable doorseal

Abstract

The invention relates to a soil taking device and a soil taking method, belonging to the field of geotechnical engineering investigation in civil engineering. The soil taking device of a starting side opening of a movable doorseal comprises a drill part and a tube body part. The soil taking device is characterized in that the tube body part comprises a plurality of sections of soil taking tubes; each section of soil taking tubes comprises a plurality of sections of soil takers; the sections of the soil takers are in threaded connection; isolations are arranged at the threaded parts; soil entering holes are formed in the isolations of the soil taker; and movable doors which fit for shapes and sizes of the soil entering holes are installed on the soil entering holes. The soil taking method of the soil taking device of the starting side opening of the movable doorseal is simple in equipment and easy to operate, the soil can be taken rapidly and conveniently, and the soil taking device can be used as a device special for rapidly measuring the cement content of a cement mixing pile and judging a thin interlayer.

Description

technical field [0001] The invention relates to a soil fetching device and a soil fetching method, which belong to the field of geotechnical engineering investigation in civil engineering and geological engineering. Background technique [0002] What the existing soil-taking device adopted is a cylindrical soil-taking device, adopts static pressure or hammering method. The soil-taking device adopts the soil-feeding method from the lower end. When the soil-taking device is pressed down, the soil enters the soil-taking device from the lower opening of the soil-taking device. The sampling rate of this soil-taking method is not high. Due to the relative sliding of the soil sample and the soil-taking device, It is difficult to determine the actual depth of the soil taken. At the same time, the height of the existing soil-taking device is generally less than 50 cm, and only one soil sample can be taken at a time. It is impossible to collect soil samples in the whole depth range ...
