A study on water collecting capacity of filter tubes and porous concrete applied in groundwater wells by using physical experiments

Abstract

This paper presents the results of the physical experiment on water collecting capacity of the filter tubes and porous concrete used in the radial and shallow wells for groundwater collecting purposes. The physical experiment aimed at determining the correlations between various parameters such as grading composition, permeability coefficient, water head, density, and tube slope with water collecting capacity of different types of filter structures. Experimental results showed that the ability of collecting water of filter tubes and hollow concrete were from 2.162 little/minute/m to 12.238 little/minute/m, and from 0.0053 little/minute/cm² to 0.0227 little/minute/cm², respectively. The horizontal water collection structures including filter tubes and porous concrete can be used in many kinds of vertical wells to exploit groundwater in windy marine sediments environment.
