Flow logging structure

The invention provides a flow logging structure. The flow logging structure comprises a vertical shaft, an open steel pipe, a flow meter, a spiral stair, a power distribution system, a ventilation system and a drainage system. The vertical shaft is a container for flow logging and plays a supporting role on surrounding soil. The open steel pipe is an underground pipeline in the vertical shaft andis used for mounting the flow meter; and the flow meter is fixedly mounted on the open steel pipe and used for monitoring the flow of a water conveying pipeline in real time. The spiral stair is fixedto the inner side of a shaft wall lining of the vertical shaft and serves as a traffic channel between the flow logging shaft bottom and the upper ground. The power distribution system is used for solving the problems of shaft illumination, flow meter power supply and power distribution of the ventilation system and the drainage system; the ventilation system is used for improving air in the vertical shaft; and the draina
