Description
Technical field
The present invention relates to engineering construction fields, and in particular to the laser of guidance system in a kind of railroad survey and constructing tunnel
Target and its measuring device.
Background technology
Shield technique is a kind of construction method in subsurface test digging tunnel, has high degree of automation, saves manpower, applies
Work speed is fast, weather proof advantage, and while excavating can control surface subsidence, reduce influence to above ground structure,
Water surface traffic is not influenced when excavating under water.Usually, it is closed in subway work and constructing tunnel using shield technique is more economical
Reason.
At present, the common posture for measuring shield machine and the method for position have：
1. manual measurement method.Forward and backward two targets are fixedly mounted in the surface of shield machine axis, assist transit survey
Azimuth of the shield machine axis under earth coordinates, is installed with gradient plate, by gravity drop hammer in the gradient on shield machine
The pitch angle and angle of rotation of position measurement shield machine on plate determine the position of shield machine finally by mounted section of jurisdiction quantity
It puts.Major defect includes existing for the method：Position measurement, pitch angle are low with the precision of rotation angular measurement；It measures and all must every time
Data must be manually read, measurement efficiency is low；High, working strength height is required survey engineer, it is big to shield-tunneling construction interference.
2. polygon prism mensuration.Two or three prisms on shield machine are installed, pass through intelligent total powerstation and angle sensor
Device positions shield attitude, but in practice of construction due to being limited by sighting condition, when particularly curve tunnels, needs frequency
Numerous station of removing measures, heavy workload, and the influence of the installation site of prism to measurement accuracy is also bigger.And hardware integration degree is low, surely
It is qualitative poor.
3rd, electronic laser target mensuration.Pass through the relative position of hot spot, the prism being fixedly mounted and angle on target before and after measurement
Sensor is spent to determine the orientation of shield and attitude angle.This measuring method principle is simple, but incident laser direct irradiation exists
Camera lens damage is be easy to cause on camera lens, need to frequently replace camera lens, measurement cost is high.
In view of this, a kind of high integrated level, laser target at low cost and its measuring device how are designed, is treated with accurate measurement
Survey the position of object, the accurate measurement that can be in the case of intervisibility limited space especially faced in shield-tunneling construction, be insider urgently
It need to solve the problems, such as.
Invention content
For in the prior art, shield measure present in Automatic survey is low, needs that measurement space is big, hardware integration degree
Low, poor this defect of problem low with precision of system stability, the present invention provides a kind of swashing for set of tunneling construction guidance system

System, angular transducer are fixedly connected with the babinet.As long as the installation site of angular transducer is not blocked into imaging system
Light.
After laser beam passes through the thang-kng window to realize front side board described in laser beam transparent, it is directly transferred to the light splitting
On mirror, hot spot is formed, a part of light is reflected onto first prism, and a part of light transmission passes through imaging to imaging system
Hot spot is formed after camera lens, the camera is used to shoot laser beam in the light formed on the spectroscope and on the imaging lens
Spot.
Preferably, first prism and the position of the imaging system are interchangeable.
According to another aspect of the present invention, a kind of measuring device is provided, including：

And vertical angle；
And controller, the total powerstation and the laser target are connected to, the controller is according to the laser target
Geodetic coordinates, the laser beam be incident to the laser target horizontal angle and vertical angle, with angular transducer measure it is described swash
Pitch angle and the roll angle of light target and position and the posture for calculating the laser target.
It is an advantage of the invention that：Light beam is divided into two parts using the spectroscope in laser target, direct photograph can be reduced
The light intensity of the laser on imaging lens and camera is mapped to, so as to mitigate the damage to camera；Using laser beam in different optical surfaces
The upper position for forming hot spot, in the process accurately measures it angle of eccentricity that can determine laser target, and precision is better than 0.01 °.
And it is possible to laser target and level relation of plane are measured by angular transducer, it is then sharp to further determine that by controller
The position of light target, so as to accurately measure the position of laser target and posture.This measuring apparatus is not limited by intervisibility space.
In addition, measuring apparatus is fixed on babinet, it is possible to reduce because the vibration in construction leads to error caused by equipment displacement, and is set
Standby integrated level is high, small, and can be greatly cost-effective.
