Description

Recoverable road subgrade subsides monitoring devices Technical Field The utility model relates to the technical field of road engineering monitoring, in particular to a recyclable road subgrade settlement monitoring device. Background In the filling roadbed engineering, in order to make the roadbed in a good working state, settlement monitoring needs to be carried out on each observation position of the roadbed. At present, a method of burying a sedimentation pipe is generally adopted for sedimentation monitoring of a filled roadbed, namely, one sedimentation pipe is buried vertically at different observation positions, a base with the size of 0.5 x 0.5m is welded at the lower end of the sedimentation pipe, another section of sedimentation pipe is welded at the upper end of the sedimentation pipe along with the progress of filling until the sedimentation pipe is higher than the height to be filled, after the filling is finished, the sedimentation pipe part above the filling is used as an observation point, the sedimentation pipe part is matched with a level gauge or a total station for monitoring, and after the monitoring is finished, the sedimentation pipe above a filling layer is required to be manually removed so as to meet construction conditions. Because the sedimentation pipes are constrained by the base and higher than the filling layer are generally sheared by tools such as a vice, the rest sedimentation pipes can not be taken out after being buried in the filling layer, so that steel resources are unnecessarily wasted, and the sheared sedimentation pipes can not be used as sedimentation pipes, thereby greatly increasing the cost of subsequent roadbed sedimentation monitoring. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides a recyclable road subgrade settlement monitoring device which can realize the complete recycling of a settlement pipe and ensure the low cost of subgrade settlement monitoring.
