Experimental Study on Bionic Screw Pile of Reducing Adhesion and Resistance
The surface of compound eye of ant was observed by using scanning electron microscopy technology. These characteristics on the surface were applied on cone of screw pile for preventing flood and rushing to deal with an emergency. Comparing experiments of piling were conducted before and after the bionic surface was made, and these experiments were conducted under three different soil environments, including soil among the Yellow River, the Yangtze River and the Pearl River. In the experiments, data of strain was tested and collected by dynamic strain gauge RA2300 style. The output was recorded on disc and later the data were processed by computer. The observation results showed that the compound eye of ant was made of a lot of small convex eyes. These small convex eyes were arranged in dense style. They had the characteristics of convex dome. The results of piling experiments showed that the bionic screw pile with bionic surface of cone produced better effect of reducing soil adhesion and resistance than the common screw pile with no bionic surface of cone.
