Abstract

The invention discloses a detachable visual static sounding probe. The problem that existing geotechnical engineering exploration has defects is solved. The probe is composed of a detachable cone head, a conical tip resistance measuring unit, a visual imaging unit, a side wall resistance measuring unit, an analog and digital conversion unit and a probe rod connection unit by tightly screwing high-strength screw threads. By means of the visual imaging function, an image of an exploration soil layer soil body can be dynamically shot, and soil body types are named and the soil body pollution degree are identified quickly, directly and accurately. According to the detachable probe composed of the unit components, damaged parts are convenient to replace, and the situation that a whole probe is scrapped when partly damaged is avoided. The probe is simple in structure and novel in design, and can provide visual images and accurate test parameters for geotechnical engineering exploration.

Description

technical field [0001] The invention relates to the field of geotechnical engineering, in particular to a static penetrating sounding device capable of providing visualized images and accurate test parameters, in particular to a detachable visual static penetrating probe. Background technique [0002] Static penetration testing is to use hydraulic or mechanical transmission to press the conical metal probe into the foundation soil. The probe is pressed into the resistance, and the resistance strain gauge attached to the probe is deformed correspondingly to change the resistance, which is measured by the resistance strain gauge. The micro-strain value of the resistance strain gauge is used to calculate the penetration resistance and determine the engineering properties of the foundation soil. As a common method of in-situ survey in geotechnical engineering, static penetration testing can be used to determine the deformation modulus and allowable bearing capacity of soil. [...
