Description
Technical Field
The invention relates to a high-speed railway subgrade settlement monitoring device, in particular to a protection column for a railway subgrade settlement observation scale and a manufacturing and using method thereof.
Background
In railway roadbed construction, after roadbed filling is completed, the settlement of the roadbed is observed for a period of time, observation data are recorded, a roadbed settlement observation evaluation report is provided, and the next construction can be performed after the settlement data meet the design requirements. The existing roadbed settlement observation means is that a settlement observation scale is arranged on a roadbed, the settlement amount of the scale is observed and recorded through a total station, the settlement observation scale is buried synchronously along with roadbed filling, and phenomena of collision damage or collision distortion of the observation scale easily occur in the roadbed filling process, so that the observation data is inaccurate; in order to overcome the problems, the on-site protection is carried out by sleeving a large-caliber PVC pipe outside the scale, the problem that the observation scale exposes out of the road base surface is solved by lengthening the scale and protecting the pipe along with the increase of the filling height of the roadbed, but in the connection process of the protecting pipe, the PVC pipe is difficult to keep in a vertical state all the time in the roadbed filling process due to light weight, the extrusion tilting phenomenon is easy to occur, the clamping stagnation phenomenon of the inserted observation scale is caused, when the ground subsides, the upper end of the observation scale cannot subside along with the ground, the distortion of observation data is directly caused, and the serious hidden trouble of subsequent construction is brought. In addition, the PVC pipe joint socket part of the sectional plug-in is not firmly connected, so that the phenomenon that the filler enters the PVC pipe easily occurs, the entering filler also causes the clamping stagnation of the observation scale, and the phenomenon that the observation scale does not sink along with the ground occurs.
