Experimental Investigation On The Water Power Character Of The Infiltration Ditch

Abstract: The infiltration ditch uses the ditch and channel with holes to obtain water through the infiltration and gravity of water. The design of infiltration ditch contains the obtaining water tube, anti-filter layer, well, pump house and other accessory building. Nowadays, many country's factory and city use infiltration ditch to obtain water.The amount of water production whether come up to the demand is very critical to measure the infiltration ditch's success or failure. Therefore, the study on the hydraulic characteristics of the infiltration ditch has a great significance.Through the theories analysis, combining with the experiment, the water power character of infiltration ditch has been studied in this paper. The main result of study can be shown as follows:1. We must pay more attention to the location of the infiltration ditch. We'd better choose the middle of river for the obtaining water place, because it has a high current velocity and low muddy degree, the silt up degree at this part of river bed is not severity compared with others.2. The conception of the amount of water production ratio and the length diameter ratio of filter tube is proposed in this paper. The experience formula of the amount of water production ratio and the length diameter ratio is also given. Because the variate of the formula has no scale, so the formula is adapt to a broad scope.3. Through the study of scale, the no scale number has been defined. The infiltration ditch hole rate and the no scale numberφ's experience formula is got:φ= 0.0664 n+ 0.4079. The mensurable relation of infiltration ditch's water production and the filter tube's hole rate can be reflected from the experience formula. Because the formula is made up of no scale number, so it can be used widely in the engineering.The infiltration ditch is a horizontal catchment build, which has advantage of design and construction easily implement, low cost, good quality of obtain water, strong applicability, high capability of disposing sand and well accepted by users. So the infiltration ditch is used to obtain river and bank water, which has a efficient result to improve the drinking water of people and animals in Xin Jiang. The study achievement of this paper will make contribution to the application of the infiltration ditch engineering in Xin Jiang.
