  • Horizontal drains to stabilize clay slopes Canadian

    Five horizontal drains were installed in a natural clay slope and the piezometric heads in the slope were monitored with piezometers. Decreases of piezometric head in the vicinity of the drains were measured and indicated that horizontal drains can be used to improve the stability of clay slopes.Based on the theory of consolidation, estimates were made of the changes of piezometric head within the test slope due to the installation of drains

    In the Steam-assisted Gravity Drainage (SAGD) process, heated oil drains from around growing steam chambers, driven by gravity, to lower horizontal wells. As the oil drains, the steam chamber advances into the reservoir. The process has several features: The displacement or the oil is systematic and high recoveries can be obtained.

The rushing toilet water would not rob the vanity p-trap of air because it can get plenty of air in the 3-inch pipe. Some plumbers and inspectors call this wet venting. In
