Abstract

The invention relates to a geological model test gushing substance testing device and its use method, which mainly consists of an inlet pipe, a connecting piece, a vertical outlet pipe, a horizontal outlet pipe, a flow meter, a spacer and a valve, and the connecting piece is a three-way The right end of the inlet pipe is connected to the left end opening of the connector, the top of the vertical outlet pipe is connected to the lower opening of the connector, the left end of the flowmeter is connected to the right end of the connector, and the right end of the flowmeter is connected to the horizontal outlet pipe. Connection; the spacer is set in the connector, and the valve is installed on the vertical outlet pipe. The present invention can collect tunnel and underground engineering water and mud inrush model test disaster gushes, can reflect the change law of groundwater and gushes in real time, and can calculate the change of rock and soil porosity with time, which is relevant Theoretical research provides accurate basic data.

Description

technical field [0001] The present invention relates to a geological model test gushing object testing device and its use method, and proposes a device for quickly testing the speed and flow rate of gushing matter, especially suitable for rock mass porosity in model tests of water and mud inrush in tunnels in fault fracture zones Acquisition of change. Background technique [0002] As more and more tunnels pass through unfavorable geological bodies, water and mud inrush disasters often occur during tunnel construction. Geological model tests are an effective research method. To study the occurrence of disasters, it is necessary to analyze the rock mass during tunnel excavation. To monitor the change of porosity, it is necessary to monitor the gushing speed and flow rate of solid particles and groundwater during the test. However, at present, there are great deficiencies in such devices. When carrying out model tests, collection devices and test methods with extremely low pr...
