Embodiment Construction

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0029] Such as figure 1 and figure 2 As shown, the rock mass seepage path observation device based on isotope tracer technology includes a rock mass sample 4, the rock mass sample 4 is vertically arranged, a water inlet is provided at the upper end of the rock mass sample 4, and a water inlet is provided at the lower end of the rock mass sample 4. At the water outlet, the rock mass sample 4 circulates a radioactive isotope tracer mixed with the liquid from the water inlet to the water outlet. A support 1 is provided on one side of the rock mass sample 4, and a lifting device 7 is provided on the support 1. The lifting device 7 is provided with a detector for tracking the radiation emitted by the radioactive isotope. The lifting device 7 is a screw lift driven by a power device...

Abstract

The invention discloses a rock mass seepage path observation device based on isotope tracer technology and a use method thereof, which comprises a rock mass sample provided with seepage holes, one end of the rock mass sample is provided with a water inlet, and the other end is provided with a water outlet , the rock mass sample has a radioactive isotope tracer mixed with the liquid flowing from the water inlet to the water outlet. A support is provided on one side of the rock mass sample, and a lifting device is provided on the support. Detectors of radiation emitted by radioactive isotopes. The invention is closer to practical application, and the obtained rock mass seepage path observation device based on the isotope tracer technology has simple structure and convenient operation, and can accurately describe the seepage path of groundwater in the rock mass.

Description

technical field [0001] The invention relates to the technical field of rock mass seepage path observation methods, in particular to a rock mass seepage path observation device based on isotope tracing technology and a use method thereof. Background technique [0002] Tunnels and underground projects are often located in the rock mass below the ground, and are often affected by some geological activities, which affect the normal function of the design. In particular, the distribution and movement of groundwater have seriously affected the safety and stability of underground engineering structures. However, due to the impenetrability of the rock mass medium, its engineering structure is difficult to observe directly, and it has strong concealment. In actual engineering, the study of the seepage path and flow law of water in rock mass has extremely important theoretical value and effect on the mechanism and prediction of water inrush and landslide. [0003] Since the 1930s, w...
