Description
Technical field
The present invention relates to a kind of for the pre- fluid injection communicating pipe of hydrostatic leveling and its application method, is mainly used for eliminating
In hydrostatic level communicating pipe bubble can not timely and effective influence of the discharge to measure field installation effectiveness and bubble to static(al) water
Quasi- instrument measurement leads to the problem of interference, belongs to building settlement amount field of precision measurement.
Background technique
In recent years, Pile Underpinning Technology is widely applied in building field.After the completion of underpining, stake and the sedimentation need by exchange pillar
It is accurately measured, capital is risen back in situ, damage of the elimination differential settlement to building by settling amount.Stake and column sedimentation amount
General optical level can be used in measurement, but error on line of sight is larger in this way, and each measuring point measures repeated measurement work
Work amount is big.And since the sight of inner post is by the obstruction of external wall, the sedimentation of inner post is unable to measure.
For the sedimentation of precise measurement stake and column, hydrostatic level can be used.Hydrostatic level utilizes fluid connection pipe
Principle can obtain the relative settlement of each measuring point using the variation of each measuring point liquid level of computer-automatic collection.Use static level
Instrument measures differential settlement precision height, high-efficient, can continuously measure.But the measurement result of hydrostatic level may have larger mistake
Difference, main cause include: that each measuring point air pressure is inconsistent, there are bubbles in the temperature difference larger, communicating pipe communicating pipe.The first two factor
Can effectively solve at present, but in communicating pipe there are bubble at present only by beat communicating pipe, repeatedly water filling the methods of, need
Having people's operation of higher experience could smoothly succeed, and take time and effort, seriously affect the installation effectiveness of hydrostatic level, restrict quiet
The application of power measurement of the level technology.
In particular, when in pipe remain micro-bubble do not find when, measurement accuracy is very poor, in addition generate mistake as a result,
Lead to counter-measure fault of constructing, hidden trouble is come to structure safety belt.
Summary of the invention
The purpose of the present invention is eliminate bubble in hydrostatic level communicating pipe and timely and effective can not be discharged to pacify measure field
The influence and bubble for filling efficiency lead to the problem of interference to hydrostatic level measurement.
