室外管网给水管与排水管间距应该是多少
给水管道与污水管道在不同标高平行敷设时,笔直距离在500mm以内时,给水管管径小于等于200mm时,两管管壁水平距离不得小于1.5mm,管径大于200mm的,不得小于3m.给水管与排水排出 管的水平距离不得小于1m,室内给水管与排水管平行敷设时净距不得小于0.5m,穿插敷设时,笔直净距不得小于0.15m.
给水管应敷设在排水管上面,若给水管有必要敷设在排水管下面,给水管应该加套管,其长度不得小于排水管管径的3倍。排水管主要用途 高速公路纵向、横向排水及透水;
高速公路各种档土墙反面及边沟笔直、水平排水;地道、地下道之排水;市政工程、净水厂、污水厂、垃圾场等给排水;高尔夫球场、运动场、公园等休歇绿洲之排水;山坡地开发边坡水土保持;整地工程之地下排水。
