Description
Technical field
The present invention relates to a kind of high-speed railway subgrade settlement monitoring device, more particularly to a kind of railroad bed settlement observation mark
Chi protection post and its making application method.
Background technology
In railway bed construction, after the completion of roadbed filling, the observation of a period of time, note are carried out to the sedimentation of roadbed
Record observation data, provide the Settlement Observation assessment report, settling data meets after design requirement, could carry out applying for next step
Work.Existing the Settlement Observation means are the laying settlement observation scales on roadbed, pass through settling amount of the total powerstation to scale
Record is observed, settlement observation scale follows roadbed filling synchronously embedded, during roadbed filling, easily touched
The phenomenon of askew observation scale is damaged or touched, causes observation data inaccurate；In order to overcome problem above, scene is by scale overcoat
Connect a bigbore pvc pipe to be protected, as roadbed filling highly increases, solve to see by spreading scale and protecting tube
The problem of chi exposes road bed is surveyed, but in protecting tube connection procedure, because pvc pipe is lightweight, it is difficult in roadbed filling process
In remain plumbness, easily occur extruding tilt phenomenon, cause the observation scale that wherein patches to occur catching phenomenon, when
During surface subsidence, sight gauge upper end will not follow surface subsidence, directly contribute observation data distortion, bring the weight of subsequent construction
Big hidden danger.Further, since connection is insecure at the pvc pipe plug receptacle of segmentation grafting, easily occurs filler and enter showing for pvc pipe
As the filler of entrance can also cause observation scale clamping stagnation, will also result in observation scale and do not occur with the phenomenon of surface subsidence.
