Simulation tunnel leak's simple and easy device

The utility model relates to a simulation tunnel leak's simple and easy device, the device include ground simulation container and set up the tunnel simulation pipeline in ground simulation container, ground simulation container in still fill out to spread and have the soil layer, tunnel simulation pipeline run through in whole soil layer, and the inner wall of tunnel simulation pipeline on evenly laid one deck millimeter graph paper, even coating has the water of chance thermoChromic on this millimeter graph paper. Compared with the prior art, the utility model has the advantages that the whole structure is simple it is single, adopt the millimeter graph paper, can be used to mock standard checkering section of jurisdiction structure model to evenly coat the one deck at the millimeter graph paper and meet water thermoChromic, when taking place the water logging and leak, easily observe the percolating water position, become transparent square number through calculating, can effective scope of confirming percolating water, the cost of manufacture is low, economical and practical.
