Cast-in-place pile leaking stoppage and hole fixing structure

A cast-in-place pile leaking stoppage and hole fixing structure comprises a cast-in-place pile hole formed in a stratum, a plurality of leaking stoppage holes and wall fixing holes are formed in the circumference of the cast-in-place pile hole, grout is poured into the leaking stoppage holes and the wall fixing holes, and a reinforcing area for reinforcing an easily-leaked and easily-collapsed layer in the stratum is formed in the edge of the cast-in-place pile hole. The cast-in-place pile construction device is suitable for cast-in-place pile construction of easy-collapse and easy-leakage stratums such as gravels, pebbles and limestone, easy to operate and capable of effectively avoiding quality problems such as slurry leakage and hole collapse in the cast-in-place pile construction process, guaranteeing cast-in-place pile construction to be continuous and smooth, improving cast-in-place pile construction efficiency, reducing rework after quality problems occur in cast-in cast-in cast-in-in-place pile hole f
