Hydrogeological exploration drilling method

Abstract

The invention discloses a hydrogeological exploration drilling method. The method is characterized by comprising the following steps that S1, a geological exploration drilling device is designed and manufactured; s2, a drilling worker covers a control block of the geological exploration drilling device and enables a drill bit to stretch into soil at the hydrogeological position by stepping on the upper surface of a protective shell; and S3, after the opening reaches a corresponding depth, stopping treading the protective shell, pressing a control button, enabling the motor to start to operate, automatically extending the sampling barrel out of the opening under the action of an auxiliary component so as to collect the soil in the transverse moving range of the feeding hole into the sampling barrel, then stopping and rotating for a half cycle, and finally automatically collecting the sampling barrel into the protective shell. The sampling barrel is rotated by half circle again to enable the discharging opening to face downwards, so that the soil in the sampling barrel can fall to the soil storage position of the protective shell due to self weight; s4, after depth sampling at the position is completed, treading the upper surface of the protective shell; and S5, repeating the operation steps in the step S4 to sample hydrogeological soil drilling at different depths.

Description

technical field [0001] The invention relates to the technical field of hydrogeological sampling, in particular to a drilling method for hydrogeological exploration. Background technique [0002] When soil exploration of hydrogeological accessories is carried out, soil samples of a certain depth are generally taken out from the ground by artificial drilling and then hydrological and hydrogeological exploration is carried out. [0003] However, when drilling and sampling the soil, it is only possible to excavate the entire soil in a certain place. It is difficult to conduct soil sampling at different depths for comparison, and each time the soil at a depth is collected, it needs to be taken out. And pour it out manually, which is more complicated to operate. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a drilling method for hydrogeological exploration, which is capable of automatically sampling hydrogeological soils of different depth...
