水准尺

减轻了测量人员的工作强度，解除了人为控制水准尺垂直的思想负担。

The working strength of the survey person can be reduced , and the idea burden of the perpendicularity of the manual control leveling rod can be relieved .

这种方法采用经纬一次架设，配合5m水准尺，用水准仪测量两点高差，再通过计算就可以准确的测量出桩孔的倾斜度和斜距。

Using theodolite spanning , it can measure the gradient and slant distance of pile hole by measure the elevation difference of two points with water level ruler .
