The invention discloses an anti-drainage construction method for a basement in a water-rich zone of a hill along a river. A drainage mode which is combined with an open drain and a spray drain is adopted in the far shear wall area of the basement, the open drain and the spray drain are independent from each other and do not communicate with each other, water seepage of the concrete bottom plate ofthe basement is guided into the spray drain through a hydrophobic plate, water in a basement building surface layer is collected through the open drain, and collected water is guided into a water collecting well through the open drain and the spray drain respectively. Water seepage and water accumulation are collected into the water collecting well, so that the problem of leakage and ponding of the basement floor of the water-rich zone of a hill along the river is effectively solved. A narrow groove is also formed in parallel on the basis of the open drain and the spray drain at the near shear wall, so that once the water seepage phenomenon of the shear wall occurs, the water seepage of the shear wall can be collected through the narrow groove and guided into the open drain, the internalenvironment of the basement is prevented from being wet.
