Description

A surveying and mapping ruler for building inclination measurement

technical field

The utility model relates to a surveying and mapping ruler, in particular to a surveying and mapping ruler for building inclination measurement.

Background technique

测得这个投影长度x需要用尺来量取。Affected by various factors, the building will be tilted and deformed when it is put into use, resulting in potential safety hazards. Therefore, in general, the building will be regularly monitored for tilt. The most commonly used inclinometer method for residential buildings is the theodolite projection method, that is, the height h of the building is known, the theodolite is placed on the same vertical line as the top observation point, and then the top observation point is measured by the instrument and projected to the bottom. Projection length x on the horizontal plane of the observation point to obtain the inclination

To measure this projection length x needs to be measured with a ruler.

At present, a ruler or a tape measure is used to observe the projection length, and there are still some shortcomings in the actual operation process. First of all, just placing the ruler manually cannot guarantee the level of the ruler and the earth, which will inevitably cause errors. Secondly, in the measurement process, two or more measurement personnel are required, which wastes manpower in special cases.
