Description

A rapid drilling water injection test device for concrete anti-seepage wall and its detection method

Technical field

The invention belongs to the technical field of concrete anti-seepage wall detection, and more specifically, relates to a concrete anti-seepage wall rapid drilling water injection test device and a detection method thereof.

Background technique

In hydropower projects, the concrete cutoff wall has a high level of impermeability, and its permeability is extremely water-permeable. The connectivity between the test sections in the borehole is poor and the hole wall is stable. Generally, one section is drilled and one section is filled with water to test, which leads to the failure of the drilled hole. The waste of geological drilling rig equipment resources and the long time of water injection test result in low detection efficiency. At the same time, according to the current industry standard "Hydropower Engineering Borehole Water Injection Test Procedure" (NB/T 35104-2017), the groundwater level should be observed before the water injection test. Therefore, it is generally necessary to drill another water level observation hole near the water injection test hole, which requires Sufficient testing resources must be allocated to carry out water injection tests.

Therefore, water pressure plugs can be used to separate each test section and carry out water injection tests at the same time, thereby improving detection efficiency. At the same time, since the drilling of the concrete anti-seepage wall is completed at one time, the original groundwater level can be obtained based on this inspection hole, without the need to indirectly drill holes around to test the groundwater level, thus making the water injection test more accurate and saving time on surrounding areas. Detection resources for punch holes.
