Temperature cycle test device of aerated water rock

Abstract

The invention discloses a temperature cycle test device of an aerated water rock. The temperature cycle test device of the aerated water rock comprises an insulation aerated water chamber and a water tank, wherein the insulation aerated water chamber is communicated with the water tank through a water injection pipe; the water injection pipe is provided with an inlet valve; the insulation aerated water chamber is provided with an air pipe and a cooling device for cooling air in the insulation aerated water chamber; the air pipe is connected with an air input pipe and a vacuum pump for vacuumizing the insulation aerated water chamber; the air input pipe is provided with an inlet valve; a test piece clamp for fixing a rock test piece in air is arranged in the insulation aerated water chamber; the bottom of the insulation aerated water chamber is connected with a drain pipe; the drain pipe is provided with a drain valve; a heating device for heating water in the water tank is arranged in the water tank. The temperature cycle test device of the aerated water rock can realize water aeration and real-time water replenishing, does not need to move rock test pieces, is simple in structure, convenient to use and low in production cost, and can be popularized and applied conveniently.

Description

technical field [0001] The invention relates to a testing machine, in particular to a temperature cycle testing device for water-saturated rock blocks. Background technique [0002] The change of mechanical properties of water-saturated rocks under the action of high and low temperature cycles has always been a difficult point in rock mechanics research (the minimum temperature here is -30 °C, and the maximum temperature is 80 °C). Requirements, it is impossible to ensure that the rock sample can be subjected to high and low temperature cycle tests while being fully saturated with water. The traditional experimental method is often as follows: first, the sample is saturated with water in the saturated water test device, and then the sample is taken out and put into the temperature cycle testing machine. Because it involves saturated water sampling and replacement of the test instrument, the test effect must be relatively large. error. Moreover, the current high and low tem...

[0002] The change of mechanical properties of saturated rocks under high and low temperature cycles has always been a difficult point in rock mechanics research (the lowest temperature here is -30°C, and the highest temperature is 80°C). requirements, it is impossible to ensure that the rock sample can be subjected to high and low temperature cycle tests while being fully saturated with water

The traditional experimental method is often as follows: first, complete the water saturation of the sample in the water saturation test device, and then take the sample out and put it into the temperature cycle testing machine. Because it involves water saturation sampling and replacement of test instruments, the test effect must be relatively large. error

Moreover, the current high and low temperature cycle testing machine does not have the function of replenishing water. Under the condition of repeated high and low temperature cycles, the water loss of the sample is obvious, and the test effect is not ideal.
