Mathematical model of seepage flow about waterlocks groundwork is set up, Infiltration room and haplont are ascertained too. Engineering example is given.
So, as the complement for the bimaceral polyurea, the single-polyurea has the wide application foreground in the anti-crash and anti-seepage in the hydropower project.
The dependences of seepage velocity and bending strength on agglomerant content, forming pressure, particle diameter of the aggregate, soaking time, firing temperature and so on were discussed.
