Abstract
This utility model relates to a water injection device for hydraulic engineering testing, belonging to the technical field of water injection for hydraulic engineering testing. The water injection device includes: a placement frame with a water cylinder at its top and a water injection pipe connected to its bottom end; and an anti-clogging mechanism including a filter frame fixedly connected to the lower end of the water injection pipe surface. The filter frame prevents particulate impurities in the drilled soil and rock mass from adhering to the water outlet at the bottom of the water injection pipe, thus avoiding clogging. Multiple water outlets at the bottom of the water injection pipe ensure uniform water injection into the drilled soil and rock mass, thereby ensuring the accuracy of permeability tests on the surrounding soil and rock mass. The blocking block prevents the surface and bottom of the filter frame from directly contacting the inner wall of the drilled soil and rock mass, further reducing the probability of clogging and ensuring the effective water injection into the drilled soil and rock mass.
