Stilling pool base plate hydraulic pressure balance structure and construction method thereof
The invention discloses a stilling pool base plate hydraulic pressure balance structure and a construction method thereof, and belongs to the technical field of water resources and hydropower Engineering. The stilling pool base plate hydraulic pressure balance structure and the construction method thereof comprises a stilling pool foundation surface, drainage outlets and a stilling pool base plate; the drainage outlets are distributed between the stilling pool foundation surface and the stilling pool base plate and among the stilling pool base plate; the drainage outlets comprise longitudinal drainage outlets, transverse drainage outlets and vertical drainage outlets; the longitudinal drainage outlets, the transverse drainage outlets and the vertical drainage outlets are all communicated with each other; graded broken stones also are arranged between the stilling pool base plate and the stilling pool foundation surface. According to the technical scheme, the drainage outlets formed by hollow bricks staggering in longitudinal, transverse, and vertical directions are arranged between the stilling pool base plate and the stilling pool foundation surface and among the stilling pool base plate, and the interior and the exterior of the stilling pool base plate are communicated with each other and therefore water from the stilling pool base plate can successfully discharge, the uplift pressure under the base plate is reduced, differences in pressure between the interior and the exterior of the base plate is close or equal, and the stability of the stilling pool base plate is ensured effectively.
