Description

Accurate measuring leveling rod

Technical Field

The invention relates to the technical field of engineering measurement articles, in particular to a leveling rod for accurate measurement.

Background

In surveying and mapping, a level gauge is one of indispensable tools for transmitting elevation so as to establish a coordinated elevation system; in the construction industry, the level gauge plays an important role from early site leveling, foundation pit excavation to later main body construction until the whole project is finished. The leveling rod is an instrument for measuring the height difference between two points on the ground according to the leveling principle. At present, most leveling rods are made of wood, aluminum or glass fiber reinforced plastic, the length of the leveling rod is 3 meters, and two leveling rods are used as a pair and on two sides.

At present, the use of levelling rod is very general during leveling, especially the station number that needs to establish when carrying out leveling on a large scale is very many, and every station all need read foresight and twice reading of back vision, if come according to the conventionality, need artificial holding up the chi, place the bottom center of levelling rod in the original point of level earlier, both hands hold up the levelling rod and do not make it rock, because the levelling rod chi body has a take the altitude, weight is great, often can appear rocking holding up the levelling rod, even slight rocking also can lead to measured data to appear the deviation, the degree of accuracy reduces. Although the existing market has the support-free leveling rod, the positions of the original points of some leveling rods are established close to the wall edge, so that the leveling rods cannot be placed on the original points of the leveling rods; the accuracy is relatively difficult to transfer when present levelling rod adjusts vertically, can only carry out rough adjustment through swing levelling rod to the location can not be accurate completely, and the error can one step of accumulation, and reading is very probably transfinite when handling data at last, in case the reading transfinites, must retest, if not retest can influence the quality of measuring, and the retest can delay manpower and materials.
