Abstract

The present invention discloses a model test device for ground collapse caused by pipeline leakage, including a sand box, a pipeline water circulation device, a groundwater replenishment device, a water storage tank and a water head measuring pipe set. The sand box includes a sand box body and a mesh sieve plate. There are two mesh sieve plate which divides an inner cavity of the sand box into a penetration cavity and a test cavity. Corresponding positions on the side wall of the test cavity are provided with a tunnel construction hole and a plurality of pipe mounting hole groups, respectively. One side wall of the test cavity is provided with a plurality of rows. There is a plurality of rows of water head measuring hole groups, and each row is provided with a plurality of the water head measuring hole groups.
