In hydrostatic level communicating pipe, bubble timely and effective cannot discharge impact to measure field installation effectiveness and bubble to static(al) water
Quasi- instrument measurement produces the problem of interference, belongs to building settlement amount field of precision measurement.
Background technology
In recent years, Pile Underpinning Technology is extensively applied in building field.After the completion of underpining, stake and by exchange pillar sedimentation need
It is accurately measured, by settling amount, capital is risen back in situ, eliminate the infringement to building for the differential settlement.Stake and column sedimentation amount
Measurement can be using general optical level, but error on line of sight is larger in this way, and each measuring point measures repeated measurement work
Work amount is big.And because the sight line of inner post is hindered by external wall, the sedimentation of inner post cannot measure.
For the sedimentation of accurate measurement stake and post, hydrostatic level can be adopted.Hydrostatic level utilizes fluid connection pipe
Principle, using the change of each measuring point liquid level of computer-automatic collection, can draw the relative settlement of each measuring point.Using static level
Instrument measures differential settlement high precision, efficiency high, can continuously measure.But larger mistake may be there is in the measurement result of hydrostatic level
Difference, main cause includes：Each measuring point air pressure is inconsistent, there is bubble in the temperature difference larger, communicating pipe communicating pipe.The first two factor
With effectively solving, but can there is bubble in communicating pipe at present only by beaing communicating pipe, the repeatedly method such as water filling at present, need
The people having higher experience operates could be smoothly successful, takes time and effort, has a strong impact on the installation effectiveness of hydrostatic level, governs quiet
The application of power measurement of the level technology.
Particularly, when in pipe, residual micro-bubble does not find, certainty of measurement is very poor, or even produces the result of mistake,
Lead to counter-measure error of constructing, hidden trouble is brought safely to structure.
Content of the invention
The purpose of the present invention is to eliminate bubble in hydrostatic level communicating pipe and cannot timely and effective discharge measure field is pacified
The impact of dress efficiency and bubble produce the problem of interference to hydrostatic level measurement.
