Pressurized water test equipment for geological survey of hydrological engineering

The invention discloses a hydraulic test device for hydrological engineering geological survey, which structurally comprises a measurement display instrument, a case, a water tank and a connector, the measurement display instrument is mounted on the case, the water tank is connected to the side edge of the case, the water tank is provided with the connector, the connector is connected with a sleeve, a connecting pipe and a test cylinder, the connecting pipe is fixed by the sleeve, and the test cylinder is fixed by the connecting pipe. The test cylinder is matched with the matching cylinder piece, the first matching sleeve, the second matching sleeve and the third matching sleeve form a telescopic matching sleeve, the test cylinder adopts the minimum size, and when the test cylinder stretches into the ground surface, the test cylinder can be matched with the ground surface along with continuous reduction of rock mass gaps under the ground surface. The first matching sleeve and the second matching sleeve slide
