抑制型下水道是减少流入下水道或河流中的雨水量,而控制雨水径流的基本方法是“渗透”和“贮留”,两者得兼并采用。不然就不能充分发挥抑制型下水道控制雨水径流的效果。 “渗透”是为减少雨水径流的绝对值。一
Suppression sewers are designed to reduce the amount of rainwater that flows into sewers or rivers. The basic method of controlling stormwater runoff is “infiltration” and “reserve”, both of which may be used in conjunction. Otherwise, the effect of controlled sewers to control rainwater runoff cannot be fully exerted. “Infiltration” is to reduce the absolute value of rainwater runoff. one
