Problems solved by technology

However, in the teaching process, due to the lack of relevant demonstrative experimental models, only relying on theoretical lectures cannot make a relatively complete display of underground engineering geological hazards, resulting in students' lack of firm grasp of relevant content and causal mechanisms.
[0004] Prior to the present invention, Chinese patent CN 104751725 A disclosed a teaching demonstration device and test method for slope landslides, which are used to demonstrate and clarify various works such as rainfall infiltration, loading on the upper part of the slope, earthquake load, and water storage in the upper reservoir. However, its device system ignores a series of engineering geological disasters caused by tunnel excavation under on-site working conditions. In the current era of rapid development of railway tunnels, the teaching demonstration of underground engineering geological disasters in tunnels more and more necessary

Embodiment 1

[0074] This embodiment discloses a method for using an underground engineering geological disaster teaching demonstration device, which can simulate engineering geological disasters such as water and mud inrush, ground subsidence, and landslides induced by tunnel excavation, including the following steps:

[0075] S1: Tighten the horizontal T-shaped pin into the model, and tighten the vertical T-shaped pin upward;

[0076] S2: Flip the glass plate 4 on the model box outwards, place several square gypsum blocks 13 in 2 layers in the elongated groove 3 in turn, the water and mud channel will be automatically closed, and after the gypsum blocks 13 are placed, put The glass plate 4 is turned inward to a fixed position;

[0077] S3: in the settlement tank 10 of simulating land subsidence, lay a layer of steel wire mesh 11, and fill the clay 26 in a plastic state on the steel wire mesh 11 until it is consistent with the height of the top surface of bedrock simulation filler 12;

Abstract

The invention relates to an apparatus and a method for teaching demonstration of underground engineering geological disasters. The apparatus includes a steel plate box of which the top is provided with an opening. A simulation box body is arranged in the steel plate box. A vibration control device is arranged between the steel plate box and the simulation box body. The simulation box body is filled with a base rock simulating pack. A long-bar-shaped groove is arranged in the side wall of the simulation box body. A glass plate is arranged on the side wall of the simulation box body. A settlement groove, a funnel-like groove, a mud water trough and a mud water transportation channel are arranged above the long-bar-shaped groove. A steel wire net is arranged between the bottom of the settlement groove and the long-bar-shaped groove. Gypsum bulks are arranged in the long-bar-shaped groove. During demonstration of geological disaster in underground engineering, specific damage status, suchas deformation displacement slump, surface subsidence, surface collapse, water and mud inrush in a Karst zone and the like, can be obviously observed. The apparatus can show the process of formation and movement of the underground engineering geological disasters.

Description

technical field [0001] The invention relates to the teaching and subject field of urban underground space engineering or geological engineering, in particular to an underground engineering geological disaster teaching demonstration device and method used in the teaching of engineering geology and tunnel engineering courses. Background technique [0002] Engineering geology and tunnel engineering, as important basic and professional courses for majors such as civil engineering, urban underground space engineering, water conservancy, and geological engineering, are playing an increasingly important role in the process of personnel training under the background of today's rapid development of transportation . How to use visualization tools to more effectively improve classroom efficiency and facilitate the explanation of key and difficult points in courses such as engineering geology and tunnel engineering has become an important topic at present. [0003] Various underground ...
