Title: The Innovative Contributions of Andrew W. Liao
Introduction
Andrew W. Liao is a notable inventor based in Kingwood, Texas. He has made significant contributions to the field of engineering, particularly in flood management technologies. With a total of five patents to his name, Liao's work demonstrates a commitment to innovation and practical solutions for pressing environmental challenges.
Latest Patents
One of Liao's latest patents is a flood barrier and a method for forming a flood barrier. This invention involves excavating a trench from the top surface of an earthen dike down to its foundation. A mixture of dry powder, partially hydrolyzed polyacrylamide (PHPA), fresh water, and soda ash is prepared to create a slurry. The proportions used are 20 lbs of PHPA, 4 lbs of soda ash, and 68 barrels of fresh water, resulting in a slurry with a funnel viscosity of at least 45 sec/quart. As the trench is excavated, the slurry is pumped into it immediately. A geo-membrane, 0.080 inches thick, is placed in the trench, overlapping onto the dike's surface. Finally, dry sand is pumped into the trench to displace the slurry.
