Description
[technical field]
This utility model relates to underground pipe-driving survey technical field, and a kind of distance straight line push pipe center simply controls measurement system specifically.
[background technology]
In jacking construction, in order to guarantee the most through enter hole, the direction being necessary for the jacking control head driving along with every pipe joint offsets the most up and down, downward shift uses ordinary level to control at present, and angle dialled by skew many employings laser transit in left and right or total powerstation is surveyed coordinate method and is controlled.
Technical method with existing long-distance pipe jacking center line survey, substantially carry out upper and lower off normal measurement by level gauge, in pipe, repeatedly turn station by theodolite or total powerstation manually (automatically), finally measure to head center target, so that it is determined that the left-right of push pipe center line.But use theodolite or total powerstation manual measurement the most long, easily cause waste in man-hour, and full-automatic orientation measurement system cost is expensive, adds the cost of whole engineering, thus engineering causes unnecessary waste.
[utility model content]
This utility model is the longest in order to solve prior art middle and long distance straight line push pipe manual measurement, that automatic measurement expense is too high problem, designs a kind of distance straight line push pipe center simple, that be convenient for measuring and simply controls measurement system.
To achieve these goals, a kind of distance straight line push pipe center of design simply controls measurement system, including push pipe, laser pen and scalable pen stand, the midline of described push pipe installs several scalable pen stand being equidistantly distributed and laser pens, the unified direction pointing to push pipe jacking, the Laser emission direction of laser pen, it is provided with measuring instrument in active well, sets up pipeline center line through measuring instrument, make each laser pen overlap with pipeline center line and be in same straight line.
Push pipe head center is provided with target, near the laser pen sensing target center of push pipe head, thus the upper and lower off normal in left and right controlling push pipe head.
Described measuring instrument is theodolite or total powerstation.
Described laser pen tail end center is provided with reflecting piece, and reflecting piece center is located along the same line with the beam center of front end emission.
This utility model is compared compared with measurement technology in tradition hole, has an advantage in that:
1. can be greatly shortened down-hole to measure the time every time, alleviate underground survey working strength, do not delay the jacking construction of every pipe joint, accelerating construction progress；
2. spin a little in need not pipe, it is to avoid secondary even n times turning point so that repeatedly turn the error brought at station and be minimized；
3. save instrument input cost, only need a plain transit or total powerstation, it is not necessary to configuration needs the expensive total powerstation such as band laser, band automatic motor；
4. being easy to safeguard, laser pen low price, replacing are conveniently；
4., without carrying out the measurement of higher degree with level gauge, effectively reduce and measure the working time；
6. deviation achievement instant playback, it is not necessary to convert.

[detailed description of the invention]
The utility model is described in further detail below in conjunction with the accompanying drawings, and the structure of this device and principle are the most clearly for the people of this specialty.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
Embodiment 1
As shown in Figure 1, distance straight line push pipe center simply controls measurement system and includes push pipe, laser pen and scalable pen stand, the midline of push pipe installs several scalable pen stand being equidistantly distributed and laser pens, the unified direction pointing to push pipe jacking, the Laser emission direction of laser pen, measuring instrument it is provided with in active well, pipeline center line is set up through measuring instrument, make each laser pen overlap with pipeline center line to be in same straight line, push pipe head center is provided with target, near the laser pen sensing target center of push pipe head, thus the upper and lower off normal in left and right controlling push pipe head.
Measuring method is as follows: install scalable pen stand and the unified laser pen pointing to jacking direction of laser at a certain distance at pipe d, Line beam in the pipeline that the laser transit in active well sets up is utilized to point to laser pen tail end center, open laser pen light source, regulate the relative position of each laser pen, make each laser pen overlap with pipeline center line to be in same straight line, the target center that the most previous laser pen sensing head center presets, thus the upper and lower off normal in left and right controlling push pipe head.
Concrete grammar step is as follows:
A. installing scalable pen stand, the distance of the light beam launched according to the laser pen chosen on ground determines in the concrete tube coupling of scalable pen stand installation, separates Guan Nei center according to two holes for hoist, divides middle place by the most adjustable pen stand installation inside pipe wall, sees Fig. 1；
B. laser pen tail end transformation, carries out laser pen tail end during cross divides, determining central point, sticking reflecting piece, reflecting piece center is located along the same line with the beam center of front end emission；
C. installation and debugging laser pen, according to building up station in active well and pointing to the instrument of correct direction, from rear to installing and debug the relative position of laser pen at the head of front end successively, makes each laser pen be positioned on an absolute straight line；
D. measure, utilize the time every time welding tube coupling, determine that at active well, instrument points to correct direction, survey crew is checked whether laser tube position has successively in entering pipe and is somewhat moved, utilize adjustable pen stand to adjust as mobile, at survey crew to head, measure head Target Center and laser spots distance with set square, i.e. can determine that the upper concrete numerical value of lower deviation about center line, feed back to machine room, see accompanying drawing 2.
Embodiment 1
Give as a example by branch line push pipe C4 mark engineering by Min, Shanghai.Min is given branch line C4 and is designated as Min and gives point water spot to a part in the raw water pipeline of Fengxian existing Huangpu River newly-built regulating reservoir of water intake pumping station, and bid section sets 3 active wells, 2 sections of jacking constructions altogether, and wherein 3# well is diameter to 4# well top section2600mm a length of 960m straight line 4 ‰ goes up a slope and pushes up section, belongs to long-distance pipe-jacking construction, owing to tube coupling is as the extension follow-up of top section during push pipe jacking construction, is belonging to kinetic measurement and it is necessary to unidirectional jacking to well of appearing, higher to the required precision of measurement in managing.Every pipe joint saves from hanging in, being installed to out top has the free time of 2 hours to measure in real time, turning point precision in traditional measurement method time-consumingly long, hole it cannot be guaranteed that, survey crew operation complex, and automatically guidance system measuring method cost is the highest, this section top section is again straight line, therefore uses the method in this utility model to measure.Measure in pipe-jacking project hole and need survey crew continual measurement in 24 hours, substantially every jacking one will carry out head center off normal to double section tube and measure, and this top section does not use traditional measurement method to be that the error brought to reduce turning point ensures Measurement results precision, saves labour turnover.Measure turning point measuring method in using tradition hole while using the method in section hole, straight line top to compare, thus further determine that the pluses and minuses of this method, precision, time etc..
