The influence of shift measurement；Meanwhile vaseline is smeared in interior rod outer surface, the friction excluded between interior bar and outer sleeve is perpendicular to pipeline
Influence to displacement measurement.
4, the utility model realizes that displacement meter offsets with sedimentation bar by cushion block, then guarantees that displacement meter can effective measurement pipe
Line sedimentation, it is ensured that during pipe settlement, horizontal sliding will not occur for displacement meter and pipeline to be measured.
5, the utility model can remove sedimentation bar, scalable annulus, can become earth's surface measuring device.
6, the utility model can recycle after model test, be re-used in the next item down test, and dismount
It is convenient, so that save the cost is again environmentally protective.
