Document Type and Number:
WIPO Patent Application WO/2009/030072
Kind Code:
A1
Abstract:
A method of preventing termite from eroding wood pole(5), including paving PE film around the pole, installing a sand drain and a vertical drainage pipe(4) in the soil combined with termiticides, collecting the information of the pole, measuring the concentration change of termiticides in soil, analyzing the plural observed data of the pole and termiticides, calculating the strength-decline of the pole and determining the minimum effective dose of termiticides, to make a handling procedure in application of termiticides. The method can prevent effectively termite from eroding wood pole over a long period.
