several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
    最后我们来看看电路改造的流程及误区。
    电路改造流程
    电路改造之前，需要经过严格的规划。改造的时候，需要遵循一定的流程，才能确保电路改造符合要求。
    第一步：弹线
    施工人员与业主确定定位点现场定位弹线，现场确定开关，插座的位置，并用墨斗弹出需要开槽的线。
    第二步：开槽
    用切割机沿着弹好的墨线在墙地面上切出需要暗装线管以及暗装底盒的槽。
    第三步：清理渣土
    因为刚开好槽，所以必然存在渣土，我们需要认清清楚，避免渣土对下一步施工的影响。
    第四步：安装穿线管
    根据开好的凹槽的走向用弯簧把线管握弯，两头穿进底盒上面的锁母上，安装底盒。装底盒之前要在底盒合适的位置装好锁母。
    第五步：穿线
    管内所穿电线的总横截面积不能超过线管横截面积的60%，一般情况是在相匹配的管内的线数最好不要超过3根，这样才能充分保证是活线而不是死线。
    第六步：连接各种强弱电线线头
    第七步：封闭电槽
