The constructors, adopting a method combining the technology of lowering ground water level by large diameter radial well with the technology of impervious diaphragm wall made of shotcrete, lower the ground water level to the design elevation for it at one stroke without affecting the surrounding buildings.
and the other is external wall coating, its property conforms to GB/T9755-2001(Synthetic Resin Emulsion External Wall Coating) and the tensile strength≥1.0 MPa, elongation at break≥150%, and impervious to water under 0.3 MPa for 0.5 h.
Based on Remote sensing(RS) and Geographic Information System(GIS),three images of 1989,1996 and 2000 of Fuzhou city was used to monitor land use dynamic, urban expansion and urbanization, urban heat island and impervious change.
Runoff from impervious surfaces associated with areas of residential, commercial and industrial development is commonly managed through the construction of stormwater ponds that are designed to slow runoff and reduce pollutant inputs to streams.
The aim of this study was to develop a process for obtaining an impervious prosthesis and to compare the characteristics of this dextran-impregnated graft with those of a commercially available collagen-impregnated graft.
The dextran coating is capable of rendering the graft impervious to water.
Recurrent animal imagery portrays him as literally a brute, lacking a conscience and impervious to reason.
In the rest of the paper I mainly show how operant intentionality works in and through the way we take up - or are taken up by - that which seems the most indifferent and impervious to us, namely - the world of stones.
