Abstract

The invention provides a wetting-drying cycle tester for a water rock. The wetting-drying cycle tester comprises a test chamber and a support. The support is installed at the bottom of the test chamber. Two opposite vacuum test chambers and two opposite drying chambers are fixed in the top of the test chamber. The two opposite vacuum test chambers are connected with a vacuum pump and a bi-directional water pump; the bi-directional water pump is connected with a liquid storage tank installed in the test chamber through a water control valve; the lower end of the test chamber is provided four test chamber chassis; and the bottom surface of the chassis of the test chamber is equipped with a rotatable automatic lifting rotary shaft. The tester realizes automatic control by a control unit composed of a temperature sensor, a pressure sensor, a motor, a PLC controller and a relay. The tester realizes the automation of the testing process, prevents tedious manual operations, shortens test time, accelerates testing process and reduces the error caused by manual operations.

Description

technical field [0001] The invention relates to a test instrument, in particular to a water-rock dry-wet cycle test instrument. Background technique [0002] In recent years, some progress has been made in the research on the influence of dry-wet cycle on soil strength, but there are still few researches on the influence of dry-wet cycle on rock strength at home and abroad. The well-known test operation is the "water absorption-air drying" effect according to the specification process. According to the specifications, the existing experimental operation process is to place the rock sample vertically in the saturation tank, add water to the height of H / 4 for the first time (H is the height of the specimen), and then add water to H / 2 and H / 2 every 2 hours. 3H / 4 height, after 6 hours all the specimens are submerged in water. Take it out after 48 hours, at this time, the water absorption of the test piece has been completed. Then put the test piece in the oven, keep the tempe...
