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.

A high-efficiency pre-drilling pressure meter test apparatus for deep rock mass includes a rigid drill pipe, a probe, a pressurizing device and a signal processing device. The rigid drill pipe, comprising a top end and a tail end opposite to the top end, receives a fluid medium. The probe is connected with the tail end of the rigid drill pipe and communicates with the rigid drill pipe. The probe includes a measuring chamber. The fluid medium flows from the rigid drill pipe to the measuring chamber. The pressurizing device is connected to the top end of the rigid drill pipe and applies pressure to the fluid medium. The signal processing device is electrically connected with the probe to detect deformation of the measuring chamber with the change of the pressure and volume of the fluid medium in the pressurizing device.
