Detailed description of the invention
With specific embodiment, the utility model is described in detail below in conjunction with the accompanying drawings
As it is shown in figure 1, a kind of open caisson location self-operated measuring unit has two for the full station gathering open caisson 9 position
1, one, instrument is for gathering 2, three target prisms 3 for attitude algorithm of dipmeter of open caisson attitude angle
And a rearscope 4;A set of wireless communication module group comprising three substations 5 and a main website 6, with
And a computer 7 being positioned at control centre;Wherein dipmeter 2 uses two-axis inclinometer.
Two total powerstations 1 all use and come card TM30 high precision total station, use electroceramics actuation techniques with special-shaped
Parabolic mirror surface transmission technology, has motor driving and target sights function automatically, it is ensured that even if at High Rotation Speed shape
Under state, it still is able to ensure that measurement reaches optimum precision, thus ensures that attitude algorithm data efficient is reliable.Neglecting
Target visual range, accurate lock onto target is reduced during the multiple prism in field.Possesses the automatic tracking performance of excellence, more
High actuating speed 180 °s/sec, peak acceleration 360 °s/sec.Angle measurement accuracy 0.5 ", range accuracy
0.6mm+1ppm。
For installing the observation pier 8 of total powerstation, the coordinate at its center is known.Two observation piers 8 should be buried underground
Region beyond the on-the-spot three times of settling heights of distance construction, and displacement will not be produced during well sinking and sink
Fall;Two observation piers should lay respectively at the both sides that open caisson construction is on-the-spot, it is ensured that the total powerstation being mounted above can
Observe rearscope and need the target prism measured;In the case of conditions permit, can be arranged on and around build
Build the roof of thing.
Total powerstation 2 before the start of the measurement, should be specified according to site environment and need the target prism of observation, and root
Measure searching functions target prism according to following the trail of, once the most accurately measure after lock onto target, and to work as pre-test
Calculated by coordinate go out next time tracking direction, until well sinking is to precalculated position.When open caisson occur bigger skew,
Tilting or prominent heavy, total powerstation when anticipated tracking direction cannot find target prism, then progressively expands search automatically
Scope, till finding target.In view of well sinking speed typically relatively slowly, when total powerstation is in observation
Between interval less than 10 minutes every time in the case of, do not have the situation with losing target;It addition, if there is
When one target prism is blocked or other situations cannot observe, control centre can also be according to known two ribs
Mirror coordinate and tilt meter data calculate the theoretical coordinate of the 3rd target, thus ensure measurement next time, total powerstation
May search for this target.
Two-axis inclinometer uses NA4200 high-precision tilt angle sensor, and it uses cross-compound arrangement, can adopt simultaneously
The collection open caisson longitudinal axis and the angle of inclination of transverse axis both direction, have measurement wide ranges (± 5 °~± 180 °),
Precision high (0.05 °), simple in construction, the features such as reliability is high, and stable performance, antijamming capability are strong;
Two kinds of signals of RS232 and RS485, corresponding time 0.2S, supply voltage 9-30V can be exported, can pass through
Compact power carries out continued power;There is good anti-electromagnetic interference capability, vibration and shock resistant performance, good
Reliability and stability, low noise, without time drift, meet especially open caisson vibration-sunk construction.
After dipmeter installs, also reply dipmeter carries out original state demarcation, will fix dipmeter
Current vertical and horizontal angle zero setting.Dipmeter can not also be carried out initial alignment, but to write down the most in length and breadth
The reading α ' and β ' of axle, is passed in system as known parameters, as inclination angle constant in length and breadth.Well sinking mistake
Instantaneous angular Δ α=α-α ' in journey, Δ β=β-β ', wherein, α and β is the instantaneous reading of dipmeter
Number.
Target prism 3 uses and comes the little prism of card or 360 ° of little prisms.Three target prisms are by prefabricated rigidity
Components welding is at immersed tube top, and the setting height(from bottom) difference of three prisms is not less than 20cm.Confirm prism installation
And after fixing, its relative position in open caisson coordinate system should be measured in time.In work progress, avoid executing as far as possible
Work machinery blocks prism for a long time, when using underwater excavation to sink, should also be avoided mud and splashes on prism camera lens.
It addition, should also be avoided the impact that prism is caused relative to position by work progress, otherwise answer suspension of works, again survey
The relative position of amount prism.
Open caisson can be sinking of producing once, it is also possible to be that merogenesis makes, and not by section form, makes material
Material, the impact of construction method.Open caisson when carrying out merogenesis and making, then needs weight before every secondary segment sinks to starting
Newly installed prism and dipmeter, and remeasure three target prisms coordinate under open caisson coordinate system, and obtain
Take the initial reading of dipmeter, the most again specify the tracking orientation of target prism for total powerstation.
Rearscope 4 should be arranged on the known coordinate that position is fixing equally, and choosing of its position should be able to meet two
Platform total powerstation all can carry out orientation by backsight, and the distance of two total powerstations of rearscope distance should be not less than
250m。
Communication module uses the wireless data sending mode of point to multi--point, and wherein main website passes through RS232 Serial Port Line and meter
Calculation machine connects, and two total powerstations and a dipmeter are each via RS232 or RS485 communication Serial Port Line and slave station
Connect, the most i.e. form a main website and the wireless communication networks of three substations.Owing to this network communication channel is half pair
Work, communication is coordinated completely by main website control, and main website uses the Frame of band address code to send data or order,
Substation all accepts, and according to the comparison of address code, Response to selection.Each substation volume is little, low in energy consumption,
Stability and reliability are high, can conveniently provide the user two-way data signal transmission, detect and control.
Computer 7 can be the portable computer with serial ports, it is also possible to have serial ports translation function
Individual's palm PC or Android system mobile phone.Computer is connected with main website by Serial Port Line, and this Serial Port Line can be straight
The physical serial interface connect from computer picks out, it is also possible to be converted into by USB interface by serial ports virtual software
RS232 serial ports, to meet and the connection of main website.Control centre is in addition to responsible Remote gathers data, also
There is the function to generating date, position automatic Survey Software by built-in open caisson, adopt according to total powerstation
The position data of collection and the attitude data of dipmeter collection carry out Combined Calculation, calculate wink during well sinking
Time position deviation, dip deviation and settling amount, thus guiding construction side adjust arrangement and method for construction, it is ensured that open caisson
Center and reserved opening sink to precalculated position.It addition, open caisson can also be sunk by control centre by internet
Fall amount change curve and the center displacement change curve are sent to information sharing platform the most in real time, allow
The all participants of project more intuitively, dynamically understand open caisson construction process.
