Abstract

The invention discloses a test device for simulating a road underground disease body, which comprises a simulation box, air bags and an air pump; wherein the simulation box is a hollow box body, a water inlet and a water outlet are respectively arranged on the simulation box, the flow of water injection or water drainage can be controlled, a plurality of air bags are arranged in the simulation box, and the space outside the air bags in the simulation box is filled with machine-made sand; the air pump is communicated with the air bag and used for inflating or deflating the air bag. According to the invention, one or more underground disease bodies can be simulated at the same time in a closed environment, and a comparison test is completed to verify the technical level of each detection mechanism.

Description

technical field [0001] The invention relates to the technical field of simulation of underground disease bodies, in particular to a test device for simulating underground disease bodies of roads. Background technique [0002] Underground diseased bodies refer to unfavorable geological bodies that exist below the ground, such as cavities, voids, loose bodies, and rich water bodies that threaten urban safety. Void refers to the cavity with a certain scale developed between the hard crust on the ground and the foundation soil; cavity refers to the cavity with a certain scale that develops naturally or artificially in the underground soil; loose body refers to the obviously low density Unfavorable geological bodies in the surrounding soil; water-rich body refers to unfavorable geological bodies with water content significantly higher than the surrounding soil. [0003] The specific characteristics of each disease body are as follows: the void is located between the ground hard ...
