The sealing of the hydraulichead is very reliable due to its hard sealing design.
液力端采用硬密封结构，密封可靠性好。

Fluids flow down a hydraulic gradient, from points of higher to lower hydraulichead.
流体向水力梯度下游的流动是从水力压头较高处到水力压头较低处。

It also proposes an empirical formula for computing the relative hydraulichead at downstream of the grout curtain for infinitely deep homogeneous foundation.
