Drilling in-situ measurement system for geological exploration

Abstract

The invention discloses a drilling in-situ measurement system for geological exploration, which comprises a geological layer and an exploration hole formed in the geological layer, and a fixing assembly is fixedly mounted at the top of the geological layer. The position of the measuring end of the digital meter can be adjusted through the transverse movement of the sliding plate, namely, the position of the digital meter can be adjusted according to the exploration holes with different diameters, so that the measuring end of the digital meter can accurately abut against the inner walls of the exploration holes with different diameters. The number meter on the device can measure exploratory holes with different diameters, and the universal ball I is mounted at the measuring head of the number meter, so that the universal ball I is in rolling contact with the inner wall of the exploratory hole, the measuring head of the number meter is prevented from being in contact with the inner wall of the exploratory hole, and the measuring accuracy of the number meter is improved. The rolling contact friction coefficient is low, abrasion is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of engineering geological prospecting, in particular to a borehole in-situ measurement system for geological prospecting. Background technique [0002] Geological prospecting is the investigation and research activity 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 the discovery of mineral deposits with industrial significance in the general survey of mineral resources. In order to ascertain the quality and quantity of mineral products, as well as the technical conditions for mining and utilization, provide mineral reserves and geological data required for mine construction design, and analyze rocks and strata in a certain area. Conduct investigation and research work on geological conditions s...

Problems solved by technology

[0003] After drilling in geological exploration, it is necessary to measure the position of the drilled hole to judge the offset of the drilled hole, but the current engineering geological exploration drilling hole engineering measurement system in situ , the size of the detection end is fixed, so it generally can only measure the in-situ offset of the hole for a hole of one size, and the hole diameter of the drilled hole is inconsistent, which makes it in the process of use not flexible enough
