The invention discloses a deep foundation pit drainage structure. The deep foundation pit drainage structure comprises a concrete cushion layer. The lower surface of the concrete cushion layer is provided with geotechnical cloth. The geotechnical cloth is laid on the concrete cushion layer. Fixing screws are mounted between the geotechnical cloth and the concrete cushion layer. The lower surface of the geotechnical cloth is located on a U-shaped trench. The U-shaped trench is internally provided with a blind drain of a rectangular structure. The U-shaped trench is provided with a rectangular trench matched with the blind drain. The blind drain is internally provided with a water collection cavity. The bottom of the water collection cavity is provided with a water flow outlet. A cover plate matched with the water flow outlet is mounted at the water flow outlet. The water collection cavity is internally provided with a drainage pipe. The bottom of the drainage pipe extends into the water collection cavity. The deep foundation pit drainage structure can effectively solve the problems that the water burst phenomenon cannot be avoided and labor and time are wasted when foundation pit dewatering is conducted In the manner that slip casting is conducted in a pit or a dewatering well structure is dug for supplementation; the deep foundation pit drainage structure is good in structural performance, quick and reliable in construction and capable of effectively solving the problem of water draining of cracks of bedrock of a deep foundation pit.
