The hydraulic performance of hot-rolled Z-type steel sheet piles is a key factor in determining the need for a diversion dike. The JZ12-700 diversion dike is also a key factor. Theater engineers are also responsible for coordinating the work of topographic survey units across subordinate commands. Particular attention must be paid to the performance of the weir under flood conditions.

The primary function of the Jinxi sheet pile flood dike is to provide predictability of flow velocity and flow distribution. Engineering drawings include dedicated maps and overlay maps. In this case, there is a risk of the weir being bypassed, which could have serious consequences if not accounted for in the design.

Without a diversion dike, the flow pattern of the JZ12-700 dike cannot be predicted analytically. His JZ13-700 topographic unit generates astronomical positioning points, which are used to control the JZ13-700 map and connect to the existing triangulation system, the JZ14-700. In particular, bypassing the JZ14-700 could damage the weir's wing walls or abutments.
