Experimental study on drainage characteristic of capillary drainage belt
摘要
Abstract
In this paper, the capillary force of the drainage belt was discussed, and the laboratory experiment of sand drainage was carried out. The flow velocity, soil moisture and the anti-clogging performance in the condition of setting capillary drainage belt in sand were than analyzed. The results show that the range of suggested angle for capillary drainage belt is from 10° to 15° for slopes and other structures, and the belt strengthens the drainage capacity of the sand. What's more, buried depth only has a little influence on drainage effect in unsaturated period under variable water head, and the inverted filter could be formed under the influence of capillary drain belt. The research results provide practical value for the engineering application of capillary drainage belt.关键词
