Description
Technical field
The present invention relates to a kind of measurement mechanism, relate in particular to a kind of device for accurately measuring of space structure vertical deformation.
Background technology
Settlement of foundation is meant foundation soil densification and the foundation surface that causes sinks under the extra-stress effect.Excessive sedimentation, particularly non-uniform settling can make buildings run-off the straight, cracking consequently can not normally use.
Before buildings and earth structure are built, exist the gravity stress of soil body self gravitation in the ground already.Buildings and earth structure load pass to ground by the bottom surface of basis or embankment, the original stress state of natural soil layer is changed, under additional three-dimensional stress component effect, produced vertical, side direction and detrusion in the ground, cause the vertical and lateral shift of each point.The vertical deformation of foundation surface is called settlement of foundation, or foundation settlement, owing to reason such as building load difference and ground be inhomogeneous, the sedimentation of basis or embankment each several part is more or less always uneven, makes correspondingly to produce extra stress and distortion among superstructure or the pavement structure.Uneven settlement of foundation has surpassed certain limit, to cause the cracking of buildings, crooked even destruction, for example the crack appears in brick wall, the crane wheel card rail or slide rail, towering structure inclination, rotary shaft of machine deflection occur, departs from pier, beam face or pavement cracking etc. with fracture of buildings connecting tube and bridge.
The space structure vertical deformation is directly connected to the safety of space structure, for example the safety in seabed tunnel, subway, gymnasium.In the prior art, space structure vertical deformation measurement can not find point of fixity as benchmark, and for example the vertical deformation in the vertical deformation of the vertical deformation in tunnel, subway and gymnasium etc. can't directly adopt sensor to measure.
Summary of the invention
Technique effect of the present invention can overcome above-mentioned defective, and a kind of space structure vertical deformation measurement mechanism is provided, and it can directly be measured the vertical deformation of space structure, and is accurately convenient.
For achieving the above object, the present invention adopts following technical scheme: it comprises the benchmark hydrostatic level, measures hydrostatic level, data processing module, and benchmark hydrostatic level, measurement hydrostatic level are connected with data processing module respectively; The benchmark hydrostatic level is arranged on the fixed datum of space structure, measures the top that hydrostatic level is arranged on space structure, is communicated with by pipeline between benchmark hydrostatic level and the measurement hydrostatic level.
The node vertical deformation of grid structure inside can not be adopted displacement meter, because displacement meter can not find point of fixity in space grid structure, measures through the hydrostatic level that development and use Rock soil Foundation dam often adopts.Hydrostatic level is the intelligent displacement transducer of a kind of inductance fm class, is made up of accurate liquid level gauge, fluid reservoir and connecting pipe.By pipeline the liquid level of all liquid level gauges is communicated with, measure the relative basic point of each liquid level gauge vertically to the distortion situation.Be widely used in the precision measurement of linear road sedimentation and section sedimentation, the linear sedimentation of dam and deflection of bridge span, during installation a hydrostatic level is arranged on fixed point (horizontal basic point), other hydrostatic level is arranged on the measured point, and connects with connecting pipe.Its principle is the sedimentation and deformation by the horizontal relatively basic point in measure of the change measured point of liquid level.For the deformation observation based on vertical displacement, its method is at first according to the landform of builder's yard, geologic condition with to the accuracy requirement of deformation observation, rationally lays the Deformation control site.Near position more firm buildings is buried working base point underground, direct displacement in order to observation station on the mensuration buildings, and the stable position beyond deformation effect be buried reference point underground as far as possible, in order to the steadiness of check work basic point itself.Working base point and reference point are generally all formed net form, come testing and check with the method for precise leveling.
The benchmark hydrostatic level with measure water or oily connection the by being provided with in the pipeline between the hydrostatic level, general water or the oil of injecting in the hydrostatic level, but may can not in time heat winter owing to construction reason, for long term monitoring so with anti freezing solution replacement water, and anti freezing solution is not volatile, has added silicone oil in addition on the anti freezing solution liquid level, further prevents the anti freezing solution volatilization, reduce the loss of liquid, guarantee enough liquid flows.All measurement hydrostatic levels all are arranged on sustained height.
Data processing module is a PC, and hydrostatic level is transferred to PC with the settlement values signal and gathers automatically, has realized the real-time monitoring to space structure.Settlement monitoring adopts the method for precise leveling, mensuration is laid in the elevation of measuring point on the buildings, monitor the sedimentation situation of buildings by the elevation change of monitoring measuring point, in periodic observation process, in case when finding that the big or non-uniform settling of deflection is apparent in view, report unit in charge of construction at any time.To cause the mechanism that building is destroyed according to requirement of building operation rules and uneven settlement of foundation, generally should establish a monitoring point in each turning point junction of buildings enclosure wall.Because fixed datum is the benchmark of whole settlement monitoring,, guarantee the reliability of monitoring result so fixed datum is selected impregnable point of fixity setting usually.
Hydrostatic level, be to carry out work according to the characteristic (being connecting pipe principle) of liquid surface nature maintenance level, when the apparatus subject place of laying (measuring point) when elevation change occurring, lifting just appears in the liquid level in the apparatus subject to be changed, and measures these variable quantities and just can determine the discrepancy in elevation of each measuring point with respect to a certain basic point.
The vertical deformation of this measurement device space structure, the measuring accuracy height, performance is steady in a long-term reliable, and measurement range is big, and is highly sensitive.
