Description
Technical field
The present invention relates to engineering survey product technical field, specifically a kind of self-supporting type leveling rod.
Background technology
In mapping operations, spirit level is one of indispensable instrument, and it is used for elevation transference, so as to establish an association
The elevation system of tune；In building trade, from the levelling of the land of early stage, excavation of foundation pit, main body finally is built, until whole work
Journey terminates, and spirit level all plays an important role.Levelling rod is the instrument that ground point-to-point transmission difference in height is measured according to measurement of the level principle
Device.At present, most of levelling rod is used made by timber, aluminium or fiberglass, and chi length is mostly 3 meters, and two are one secondary, two-sided to make
With.
At present, the use of levelling rod is very universal during the measurement of the level, particularly when a wide range of measurement of the level is carried out
Need the station number that sets very more, and each station is required for reading forward sight and backsight reading twice, if routinely come, it is necessary to artificially help
Chi, first the bottom centre of levelling rod is placed in base leveling origin, both hands, which buttress levelling rod, rocks it, due to due to levelling rod
Chi body has certain altitude, and weight is larger, is rocked helping levelling rod often to occur, even if slight rocking also results in survey
There is deviation, accuracy in amount data.Although there is the levelling rod for exempting to help in the market, some base leveling origin positions are built
Vertical close wall side, causes such levelling rod not to be placed into base leveling origin；Current levelling rod regulation is compared when vertical
Difficulty is transferred to accurately, can only carry out coarse adjustment by swinging levelling rod, can not be completely accurate so as to position, and error can be step by step
Accumulation, finally reading probably transfinites when processing data, once reading transfinites, must resurvey, if do not resurveyed
The quality of measurement can be influenceed, and manpower and materials can be delayed by remeasuring.
The content of the invention
In order to solve the above problems, the present invention provides a kind of self-supporting type leveling rod, can not need artificial one in measurement
