The invention relates to the technical field of foundation pit slope water and soil loss protection, and provides a water collection protection structure for local water and soil loss between foundation pit support piles, which comprises an interception mechanism arranged between two pile bodies, a water collection mechanism arranged on the interception mechanism and a grouting mechanism arranged on the interception mechanism, the intercepting mechanism comprises a containing bag with a cavity, a supporting frame arranged in the containing bag and used for supporting the containing bag and filler arranged in the containing bag, and the two ends of the containing bag abut against the outer surfaces of the two pile bodies correspondingly. The supporting frame comprises two oppositely-arranged circular rings, two arc-shaped net plates arranged on the circular rings in parallel and a supporting rod used for connecting the two circular rings, the supporting frame is elastic, the cross section of the supporting frame in the height direction of the supporting frame is in an arc shape, and the arc shape is close to the soil body. The method has the beneficial effect that the protection effect on follow-up water and soil loss between the support piles is improved.
