Deviation rectifier is a both-side opening rectangular box, and rectangular box top and bottom arrange a pair of parallel laser mirror, Laser is injected from opening, is projected from other one side opening after parallel laser transmitting mirror decrease, and so as to reach laser beam is corrected Effect.

In the present invention:

1) generating laser is installed:

One suspension platform 8 is installed at tunnel entrance, generating laser device 1 is placed on suspension platform 8.Position First primarily determine that, make the laser beam of each transmitting of generating laser device 1 in proper height.Then adjusting foot screw 6 makes level The bubble of pipe 5 is placed in the middle, so that laser beam is parallel to the inwall of vault section of jurisdiction 9.With the increase of measurement length, need sharp by adjusting Light regulator 1b is adjusting the parameter such as intensity and spot diameter of laser.Laser head 1a is set to a datum mark, this is measured The coordinate when initial coordinate of individual datum mark and every time measurement check.

2) receptor 2 is installed:

Arrange vault receptor 2 on the vault section of jurisdiction 9 for needing monitoring in time, vault receptor 2 mainly includes one piece high Saturating vitreous body 2a, its surface grid with a scale.Concrete operations:The surface of position for needing arrangement is cleaned out, will be connect with glue Receive device to get up with section of jurisdiction inwall bonding.Then foot screw 6 on vault receptor 2 is adjusted, the gas of levelling tube 5 on vault receptor 2 is made Bubble is placed in the middle, so that the position level of vault receptor 2.Each vault receptor is installed, and generating laser is just started shooting transmitting Laser beam, by telescope 12 apart from the suitable distance reading of vault receptor 2, writes down laser through vault receptor 2 Initial coordinate, every time monitoring only needs to read-record, so obtains a series of coordinate figures of each point.If front-operated Inconvenience, receptor two sides and equally indicates below scale, thus can on other faces reading.

3) reflector 3 is installed:

Tunnel trend not necessarily straight line, what is had needs turning.That is accomplished by anti-in the correct position bonding of turning section Emitter 3.Laser mirror 11 on reflector 3 can be allowed to change direction with reflection laser.Reflecting mirror 3 is provided with corner spiral 7, can accurately finely tune the position of laser mirror 11.Obviously, linear type shield tunnel is without the need for installing.

4) Deviation rectifier 4 is installed:

Tunnel is a bit long;Meanwhile, generating laser device 1 install when may produce larger error, then height or Horizontal error can increase with laser propagation distance and constantly accumulate.When level or height error reach about 50mm, it is necessary to One Deviation rectifier 4 is set, is also bonded on vault section of jurisdiction 9 with glue, can so make laser be adjusted to correct position. Although Deviation rectifier 4 can be settled with vault, impact will not be produced on ensuing laser.Nothing if when laser displacement amount is less Need to install.

5) data processing:

Vault settlement amount is calculated:The difference of the connected reading twice of measuring point is the sedimentation in the time period, and several times difference sum is Sedimentation in several times, while to be corrected data according to tunnel face bench mark changes in coordinates;Vault absolute coordinate Obtain:Vault settlement is minimum when measuring first, then it is considered that initial coordinate just corresponds to vault absolute coordinate.Later is absolute Coordinate figure is the difference of deflection and initial absolute coordinate;Precision analysis:This measuring method estimates read bit for 0.1mm, precision 1mm, and vault receptor 2 height thoroughly vitreous body 2a four sides all around can reading, repeatedly reading can carry In high precision.
