Geological exploration instrument with position fixed point marking function

Abstract

The invention relates to the technical field of geological exploration, in particular to a geological exploration instrument with a position fixed point marking function. The geological exploration instrument comprises an exploration instrument body, a drilling unit and a marking unit, and is characterized in that the exploration instrument body is provided with the drilling unit, and the marking unit is arranged on the drilling unit. An existing positioning marking device needs to be manually carried to a designated place, and the marking efficiency of an exploration point is affected; and the existing positioning marking device cannot be suitable for the hard ground, and the firmness of the device when the device is inserted into the ground cannot be ensured; a worker can conveniently push the device to the designated place, so that the marking efficiency can be improved; according to the invention, the depth of the marking rod inserted into soil can be ensured, so that the firmness of the marking rod inserted into the ground can be ensured; and a positioning flag can be replaced by the marking rod, and the marking rod does not need to be supported by a specific device, so that a large amount of cost can be saved, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a geological prospecting instrument with the function of position fixed-point marking. Background technique [0002] Geological exploration is the investigation and research activities of conducting geological exploration and detection through various means and methods, determining the appropriate bearing layer, determining the foundation type and calculating the foundation parameters according to the foundation bearing capacity of the bearing layer. , it is necessary to mark the special exploration points in order to distinguish the exploration places later. [0003] The Chinese invention patent with the application number CN112179327A discloses a fixed-point marking device and method for geological exploration. The patent clamps the positioning flag through the extrusion plate, and can adjust the height of the positioning flag at the same time, which is suitable ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned patent also has the following problems: 1. The positioning marking device used in the above-mentioned patent is mainly supported by the drilling rod and the lifting leg, and the connecting rod is slidingly provided inside the lifting leg. When abutting against a hard ground, the lifting legs will slide relative to the connecting rod, so the lifting legs cannot be inserted into the soil, so that the firmness of the device when inserted into the ground cannot be ensured

[0005] 2. Since the positioning flag of the device requires a specific device for support, and each device can only mark one exploration point, if there are many exploration points to be marked, a large number of positioning marking devices need to be used, and the operation steps are cumbersome. and waste of cost
