Continuous sealed type interference-free sampling drilling tool of soil repairing and sampling integrated drilling machine

Abstract

The invention provides a continuous sealed type interference-free sampling drilling tool of a soil repairing and sampling integrated drilling machine. The continuous sealed type interference-free sampling drilling tool comprises an outer pipe of a sampling pipe; a matched top driving cap is arranged at the top end of the outer pipe of the sampling pipe and is used for sealing the top part of the outer pipe of the sampling pipe; the bottom end of the outer pipe of the sampling pipe is connected with a coring drill bit and the coring drill bit stretches into a soil layer to sample; a soil coringpipe is arranged in a pipe body of the outer pipe of the sampling pipe; the lower end of the soil coring pipe is communicated with the coring drill bit and is used for collecting a soil sample in a sealed manner; the upper end of the soil coring pipe is connected with one end of a core sample pipe top driving head and the core sample pipe top driving head is used for jacking the soil coring pipe;the other end of the core sample pipe top driving head is connected with one end of a vibration absorber; the other end of the vibration absorber abuts against the top driving cap. According to the continuous sealed type interference-free sampling drilling tool of the soil repairing and sampling integrated drilling machine, original physicochemical properties of the soil layer are not damaged bythe structure and an inspection effect is reliable; the sampling is convenient and rapid and a target soil sample directly enters the soil coring pipe; the continuous sealed type interference-free sampling drilling tool has the advantages of convenience and rapidness in packaging, higher efficiency and deeper sampling depth.

Description

technical field [0001] The invention belongs to the technical field of drilling rig equipment, and in particular relates to a continuous closed undisturbed sampling drilling tool mechanism of an integrated drilling rig for soil restoration. Background technique [0002] The traditional drilling tool needs to add water to rotate the sample, or use the helical blade to take the soil sample and the hand drill to sample, which will destroy the soil layer and the original physical and chemical properties. Invention content: [0003] The purpose of the present invention is to overcome the above problems existing in the prior art, and to provide a continuous closed undisturbed sampling drilling tool mechanism of a soil sampling and repairing integrated drilling rig, which can realize the original physical and chemical properties of the soil layer without destroying, the inspection effect is reliable, and the sampling For the purpose of convenience and quickness, the target soil s...
