The lock gate has a net width of 25 meters and a maximum flow rate of 78.4 cubic meters per second. It is equipped with three submersible axial flow pumps with a designed drainage flow rate of 30 cubic meters per second.

As an important component of the "6+1" flood control and drainage project in the YuYao River - Fenghua River basin, the Xiepu Lock Station has a main pump station designed with a flow rate of 250 cubic meters per second. Its single 50 cubic meters per second vertical shaft flow pump is the largest in the country. The main water gate has a total net width of 48 meters with six orifices and a designed flow rate of 349 cubic meters per second. The estimated total investment of the project is 640 million yuan.
