摘要
针对雨水渗透设施的设置条件和理论计算,对国内外规范进行分析研究。结合国外某港口工程渗透设施的实施方案,根据不同降雨时间的暴雨强度,对雨水渗透管沟、渗透井和渗透明渠的渗透量及储水量进行计算,确定了渗透设施的经济尺寸。工程实例表明,当降雨量≤91mmh和渗透系数≥0.5mms的情况下,渗透设施在雨水排放方面具有明显优势。
Aiming at the setting conditions and theoretical calculation of storm water infiltration equipment,we analyze and study the domestic and overseas codes.Combining with the implement scheme of infiltration equipment of an overseas port engineering,we calculate the infiltrated water volume and water storage of infiltrated pipe trench,infiltrated chamber and infiltrated channel according to the rainfall intensity at the different rainfall time,and determine the economical dimensions of infiltration equipment.The engineering example shows that on the condition of the rainfall is no more than 91 mm h and the soil permeability is no less than 0.5 mm s,this infiltration equipment has obvious advantages in storm water discharge.
