The utility model relates to a negative frictional force inclined correction precipitation well which has the structure that the well wall of the utility model comprises a reinforcing cage, a water filtering layer, a protective layer and a pea stone layer which are orderly outwards, wherein the bottom of the reinforcing cage is provided with a closed tapered end which bulges downwards. A high efficiency water drop well which is arranged at one opposite side corresponding to the inclination of a building (a construction) is used for adjusting and controlling a water level in a foundation, when dehydration and consolidation are carried out on the foundation, earth among piles generates down pull-negative friction, so that pile foundations endlessly sink, and because groundwater recession curves generate different effect on the adjacent piles, the down pull and the sinkage are different. The building (the construction) can lean backwards steadily and orderly, the stable negative friction generated by the high efficiency water drop well is used for correcting incline, and the utility model is a simple and efficient measure.
