Description

Technical Field

[0001] The utility model relates to the field of engineering geological survey, and more specifically, to a water pressure testing device for engineering geological survey. Background Art

[0002] In engineering geological surveys, understanding the permeability of underground rock and soil is crucial, as it helps assess groundwater flow, foundation stability, and the safety of engineering structures. Existing water pressure testing equipment has certain limitations in position adjustment flexibility, multi-angle drilling capabilities, work efficiency, and data diversity. These limitations limit the comprehensiveness and accuracy of the test.

[0003] In traditional water pressure testing equipment, the hole needs to be sealed first, and then the water injection device needs to be installed. The whole process involves multiple adjustments and replacements of equipment. The operation is complicated and time-consuming. In addition, the water flow may be unevenly distributed when passing through the drill bit nozzle, which will cause the water flow rate in some areas to be too high and the water flow in other areas to be insufficient, thus affecting the accuracy of the test results.
