Arbitrary dip angle jointed rock sample coring chassis adjusting device

Abstract

The invention discloses an arbitrary dip angle jointed rock sample coring chassis adjusting device. The device comprises a base, wherein vertical steel plates are arranged on two side surfaces of the base; an automatic lifting hydraulic jack is arranged on the base; the automatic lifting hydraulic jack is connected with a coupling plate by virtue of a shaft pin; the coupling plate is connected with a coupling support by virtue of a shaft pin; a steel plate tray with a fixed convex groove is arranged on the top of the coupling support; rigid transverse supporting rods are arranged on the vertical steel plates on the two side surfaces of the base by virtue of a shaft sleeve; two ends of the rigid transverse supporting rods are locked by virtue of a locking nut; and a protractor and a rock fixing device are arranged on the steel plate tray. According to simple automatic operation, rock samples containing different jointed rock angles are directly drilled by utilizing a conventional indoor rock drilling sampler, the instrument is easy to manufacture, the drilling precision is high, and the operation is convenient and reliable.

Description

technical field [0001] The invention belongs to the field of civil engineering, in particular to a chassis adjusting device for coring jointed rock samples with arbitrary inclination angles. Background technique [0002] In nature, most rock bodies have various geological interfaces, including material differentiation surfaces and discontinuities, such as folds, faults, bedding, joints, etc., which will make the rock mass show very obvious anisotropy characteristics , in engineering, the anisotropic properties of rock mass often determine the safety of engineering construction and engineering structures. The urgent need for discipline development. However, due to factors such as the complexity of the field test and the high cost, the current experimental research on rock mass anisotropy is mostly based on the laboratory test. The research object of the indoor test is usually carried out with a certain size of the cylindrical specimen, and the production of the cylindrical ...

Problems solved by technology

However, due to factors such as the complexity of the field test and the high cost, the current experimental research on rock mass anisotropy is mostly based on laboratory tests.

The research object of the indoor test is usually carried out with a certain size of the cylindrical specimen, and the production of the cylindrical specimen is mainly made of natural rock mass or similar materials, and when using similar materials, it is difficult to determine the similarity ratio, and Due to the limitation of indoor conditions, it is difficult to accurately simulate bedding rock mass, so it is more practical to use natural rock mass drilling samples, but due to the irregularity of natural rock mass and the current rock drilling sampling The problem of taking rock samples with different joint angles, there are great difficulties when using natural rock mass to drill joint rock samples with different angles in batches, and there is still no good method to obtain batches of samples Jointed rock mass specimens with continuous different angles
