Cast-in-place concrete pile curtain for reinforcing and supporting loess section shaft

The utility model provides a cast-in-place concrete pile curtain for reinforcing and supporting a loess section shaft, and belongs to the technical field of coal mine shaft supporting construction. In order to solve the problem that tunneling cannot be continued due to serious argillization flowing phenomena existing in a main inclined shaft and an auxiliary inclined shaft at present, two groups of curtain bodies are arranged on the outer side of an excavation pierced diameter of a shaft to be excavated, each of the two groups of curtain bodies comprises a plurality of cast-in-place piles which are uniformly spaced, and a flow guide piece is correspondingly arranged at the lower end of each cast-in-place pile; the water in the loess layer in the modifying and compacting process is discharged downwards through the flow guide part, so that the loess layer of the shaft section to be excavated meets the conditions of next-step construction, the technical obstacle that construction cannot be carried out in the sof
