Description

Technical Field

[0001] The utility model relates to the technical field of geological survey, in particular to a water pressure test device for engineering geological survey. Background Art

[0002] In the process of engineering geological investigation, the water pressure test is an in-situ test that uses high-pressure water to pressurize water into the borehole, and calculates the development of rock cracks and permeability based on the water absorption of the rock mass. The water pressure test uses special water-stopping equipment to isolate a certain length of the borehole test section, and then uses a fixed water head to press water into this section of the borehole. The water penetrates into the rock mass through the cracks around the hole wall, and the amount of water that eventually penetrates will tend to a stable value. The strength of the rock permeability can be determined based on the water pressure head, test section length and stable infiltration water volume.
