Suspended digital leveling rod and measuring method using same

Abstract

A suspended digital leveling rod is formed by mounting a hanger 2 at the top of a common digital leveling rod. The hanger 2 is fixed to a rod body and is made of the material the same as that of a bottom 4 of the leveling rod. The hanger 2 comprises a bottom 3. The flatness of the bottom 3 is equal to that of the bottom of the leveling rod, and the bottom 3 of the hanger is level to the bottom 4 of the leveling rod. By means of the suspended digital leveling rod and a measuring method using the same, the defects in measurement with the leveling rod upended can be overcome. The leveling rod can be suspended on an observation label at a higher position achieve leveling, and operating efficiency can be improved while measuring precision can be guaranteed. The leveling rod is applicable to high-speed rail settlement observation, building settlement observation, tunnel leveling and the like. The more efficient method for leveling is provided.

Description

technical field [0001] The invention belongs to the field of surveying and mapping, in particular to a digital leveling rod and a measuring method. Background technique [0002] In order to meet the design requirements, the construction of high-speed railways often adopts the method of replacing roads with bridges. In the settlement observation of high-speed railways, the settlement observation marks of bridge piers are often buried at the top of both sides of the squatting body (usually 2m-3m away from the ground), which is both beautiful and conducive to the protection of observation marks. However, in the traditional leveling survey, the principle that the bottom of the leveling rod is erected on the pad or the target point to be measured is generally followed, so the current way of laying the settlement observation mark brings great difficulties to the settlement observation. Inconvenience. In response to this inconvenience, two measures are generally taken at present,...

AI Technical Summary

Problems solved by technology

However, the operation of inverted ruler measurement is relatively difficult, which is reflected in (1) the staff who support the ruler must lift the ruler so that the bottom surface of the ruler closely adheres to the observation mark, which undoubtedly increases the burden on the staff who support the ruler

(2) When measuring with an inverted ruler, the flipping of the bubbles on the scale makes it extremely difficult for staff to judge the verticality of the scale through the bubbles

Therefore, the inverted ruler measurement cannot meet the requirements of settlement observation in terms of measurement accuracy and operability.
