SST Series Tilt Sensor Apply to Tunnel Engineering

l Measurement Tunneling process:

1) Measuring attitude of pipe pusher (Recommend Products: SST100,SST200)

2) Measuring attitude of shield machine (Recommend Products: SST400,SST2203)

3) Measuring attitude of guidance system (Recommend Products: SST400,SST2203)

4) Measuring attitude of Heading (Recommend Products: 2D-laser target, 3D-laser target)

l Monitoring the construction quality:

1) Monitoring tunnel deformation (Recommend Products: Tilt Beam sensor,SST400,SST2203)

2) Monitoring tunnel subside (Recommend Products: Tilt Beam sensor)

l Monitoring buildings surrounding tunnel.

1) Monitoring soil horizontal displacement (Recommend Products: Stationary inclinometer,Sliding inclinometer)

2) Monitoring buildings tilt (Recommend Products: SST400)

3) Monitoring soil subside (Recommend Products: Tilt Beam sensor)

1,Measuring the attitude of Construction Machinery Body.

In the application of pipe jacking tunneling machine, our SST100/200 are widely used to measuring theattitude of pipe jacking machine body, and it has been successfully bulk supply.

The SST100/200 typical characteristic:

1) Low cost, fast delivery for batch supply.

2) Good durable, strong ability for Anti electromagnetic interference.

3) High measurement accuracy: ±0.05°.

4) Can be normal work in the mud environment for a long time.

2,Monitoring the attitude of Guidance System.

In the Guidance System of tunnel construction equipment, our SST400/SST2203 tilt sensors are successfully use in Laser target (2D, 3D) of Guidance System. It better help to achieve more high accuracy' guidance control.  

The typical characteristic of SST300/400 tilt sensor are:

1) High precision and high stability.

2) Accuracy: ±0.0028°, OR more high measurement accuracy ≤0.0005°.

3) Strong ability to resist vibration and electromagnetic interference.

4) A built-in type(SST400), 79*35*27mm.

5) A External type(SST2203), IP68 protection.

3,Measuring Heading.

During the tunnel construction, measuring the heading attitude is the key factors for driving. 2D/3D Laser target is the optimal measurement equipment.

The typical characteristic as bellow:

1) It is suitable for damp and dark environment of tunnel.

2) The Measurement accuracy for displacement is 1mm.

3) The Measurement accuracy for heading is 1mm/m.

4) It's without strict requirements for spot size.

5) The effective measurement area is 80*100mm.

6) Strong resistance to vibration and EMI.

7) It can be optional output pitch/roll angle data simultaneously.

4,Monitoring the deformation and inner wall lining segment of tunnel.

During tunnel construction driving, it necessary to monitor the movement of every piece segments after finishing the  

pipe installed (like monitoring slope , monitoring subsidence ). So that to confirm the safety and quality of construction.

The typical characteristic of SST Series tilt sensors as follows:

1) High stability.

2) Especially suitable for long-term observation to relative angle change.

3) The highest angle resolution is 0.1sec.

4) Various supporting tools, easy to site network.

5) Adapted to strong electromagnetic interference, vibration, damp of tunnel environment.

5,Monitoring the detection for tunnel surrounding building.  

     During tunnel construction driving and construction are completed. The soil horizontal displacement will pose the threat to  

     tunnel and the nearby building. SST2200 Series Stationary inclinometer or Sliding inclinometer can better to measure the    

     Vertical or horizontal displacement caused by around tunnel structural deformation, Surface lateral displacement,

     Uneven subsidence of surface, etc. It can identify small changes in 0.01mm/m.
