several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate sirrors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
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 measured7

根据设计要求确定盒、箱轴线位置,以土建弹出的水平线为基准,挂线找正,标出盒、箱实际尺寸位置。
(5) 固定盒、箱
先稳住盒、箱,然后灌浆,要求砂
