2.3标记开槽位置 Mark the grooving line
线管开槽控制线要求：线管间距≧10mm、线管与砌体墙间距≧10mm，开槽控 制线宽度=线管外径+线管间距+线管距墙间距，开槽控制线布置清晰合理；严禁 水平开槽，如必须水平开槽的，水平开槽长度不得大于300mm。
Requirements for mark conduit grooving control line: between conduit&conduit minimum is 10mm, between conduit&grooving side minimum is 10mm, groove wide control line width =dia of conduit+
wide(between conduit&conduit)+ wide( between conduit&grooving side) ,and groove control line layout shoule be clear .Horizontal grooving is strictly prohibited, If horizontal grooving is necessary, the length of horizontal grooving shall not be greater than 300mm.
