Description
Technical field
The present invention relates to one kind to be used for open caisson automatic measurement system and method, specially a kind of to be used for circular open caisson sinking appearance
State automatic measurement system and method.
Background technique
Well foundation is a kind of pattern with the underground structure of drop shaft sinking construction and deep foundation.Production scale is not in recent years
Disconnected to expand, construction technology is rapidly developed, and open caisson construction method has been increasingly becoming various underground industrial buildings in embedment soil layer
With a kind of important form of civil air defense constructions and installations building enclosure, it is widely used in the every field of urban construction.In open caisson construction,
Due to difference, open caisson construction region soil layer complexity and the layer-by-layer concatenation construction of open caisson of caisson structure etc., circular open caisson exists
The problems such as often generating displacement, inclination during sinking construction, rotating and is super heavy.The matter of entire engineering is influenced whether when serious
Amount and periphery construction of structures safety, therefore, during open caisson is in sinking construction must position to open caisson and posture carry out
Monitoring, guarantee open caisson can it is safe and accurate, rapidly sink to design position.How to avoid these problems or by this
A little issue handlings will be the key that open caisson construction success or failure in the budding stage.
The positioning measurement of open caisson mainly includes well body in-plane displancement, rotation, the measurement of verticality and sinking absolute altitude.Verticality
Measurement mainly control well body sinking posture, prevents inclination and offset, and the method for measurement is more, common are following several
Kind:
(1) theodolite directly observe in collimation method: marked on vertical shaft and vertically and horizontally intersect middle line, theodolite is erected at vertical
In straight and horizontal line traffic control stake, center line is directly observed.This method is simple, at low cost most widely used；
(2) using level measurement well body angle point or middle line endpoints elevation, and the tilt angle of well body is extrapolated；
(3) vertical line ball: marking center line on the borehole wall, and right sphere is suspended on position of center line, is surveyed using steel ruler
The offset of right sphere is measured, and calculates its gradient.
The measurement of sinking absolute altitude mainly controls well body deflection.It is measured usually using level, datum mark arrangement
Outside 3 times of ranges of well body submergence depth, not by the stability region of construction infection, and observation point is set in well body.
Above-mentioned conventional measuring methods method is relatively simple, at low cost, manually carries out real-time measurement according to project progress, generally
For middle-size and small-size open caisson positioning measurement.For construction environment complexity, construction precision is more demanding and has reserving hole to position
Special sinking well engineering, conventional means are difficult to meet construction demand, and there are heavy workload, information content is small, the degree of automation is low, multi-section
The disadvantage of door information sharing difficulty, it is difficult to adapt to authorities, construction department, management department tripartite cooperate jointly and mutually supervise
Construction mechanism.
Currently, the upgrading of many Open caisson construction technologies and the requirement of construction speed efficiency are gradually attempted to survey using automatic
Amount method such as carries out automatic positioning measurement using the differential position based on GPS, also there is the full mistake using photogrammetric technology
Journey displacement monitoring.The former requirement with higher for construction environment, cannot block GPS signal in the construction process, be erected at
GPS receiver is easily impaired during caisson sinking construction at the top of open caisson, in addition GPS higher cost；For photogrammetric skill
For art, also there is very high requirement to architectural environment, the requirement to data acquisition is very high, data volume is big, system maintenance is difficult etc. lacks
Point.

Example IV:
By taking certain city huge port water factory one phase water intake engineering engineering as an example.The a little upper pipe working wells of the engineering are two C30 waterproof steel
Muscle concrete circular open caisson, outer diameter 17.6m, total sinking height 38.5m, using non-drainage subsidence.Since two push pipe well spacings are from close, most
Small spacing is only 15.2m, and submergence depth reaches 38.2m, the outer back gauge road of eastern line push pipe well only 14.9m.Two open caisson low coverages
The problem of interfering with each other necessarily is brought from construction, two open caisson change in displacement trend and lower rate need to be observed in time, therefore use this
Method carries out automatic measurement.
Since two open caisson spacing are small, construction site range is also smaller, and two open caissons carry out sinking construction, conventional measurement simultaneously
The measurement of amount method needs frequently to turn station, and the measurement process time is longer each time, and the distance of each survey station is again very short, it cannot be guaranteed that phase
To the relative accuracy of measurement.
While using automatic measurement system, also manual measurement is needed to be checked, to further determine that the excellent of this method
The problems such as disadvantage, precision.
The structure and computer and application tool of automatic measurement system device of the present invention, the three-dimensional coordinate including front-and rear-view,
Calculate the formula of deviation be for the people of this profession it is fully aware of, the innovation of the invention consists in that the combination of well-known technique,
Wireless communication transmissions equipment is turned using RS232 serial ports and carries out data transmission, a total station transmits coordinate, two total station combinations
The measurement that 4 target prisms are carried out with open caisson posture can increase the distance of data transmission, communication electricity of manually arranging when reducing measurement
The time of cable can greatly accelerate the time and the efficiency that measure work, solve the problems, such as measurement intervisibility.It should be appreciated that this place is retouched
The specific embodiment stated is only used to explain the present invention, is not used to limit invention.
