Drop well realized based on pipe jacking working well and transformation process thereof

The invention discloses a drop well realized based on a pipe-jacking working well and a transformation process thereof, and belongs to the technical field of drainage engineering. In order to solve the problem that an existing drop well transformation process is complex, the drop well comprises a well wall, an upstream rainwater pipe and a downstream rainwater pipe, the upstream rainwater pipe and the downstream rainwater pipe both communicate with the well wall, the height difference is formed between the upstream rainwater pipe and the downstream rainwater pipe, and a flow breaking device and at least one energy dissipation device are installed in the well wall. The flow breaking device is arranged at the outlet position of the upstream rainwater pipe, the energy dissipation device is arranged below the flow breaking device, and gabion net cages and gabions and energy dissipation piers are arranged at the bottom of the well. The method solves the contradictory problem that a drop well needs to be additional
