Roadbed settlement multi-layer monitoring structure and monitoring method

Abstract

The invention discloses a roadbed settlement multi-layer monitoring structure and monitoring method, and relates to the technical field of roadbed monitoring, the roadbed settlement multi-layer monitoring structure comprises a roadbed, a data acquisition and processing device and a plurality of section settlement monitoring devices, the roadbed comprises a plurality of soil layers which are sequentially arranged from bottom to top, and each section settlement monitoring device comprises a section settlement pipe, a measuring probe and a traction rope. One section settlement pipe is arranged in each soil layer, the multiple section settlement pipes correspond to one another in position in the vertical direction, the traction rope is used for driving the measuring probe to move in the section settlement pipes, and the measuring probe is connected with the data collecting and processing device. During working, the traction rope is pulled to enable the measuring probe to move from one end of the section settlement pipe to the other end of the section settlement pipe, the measuring probe transmits measured data to the data acquisition and processing device, the data is processed to obtain a settlement value of each node in each soil layer, and the requirements of monitoring section settlement and layered settlement of a roadbed can be met at the same time; and roadbed construction is not affected, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of roadbed monitoring, in particular to a roadbed settlement multi-layer monitoring structure and a monitoring method. Background technique [0002] In the construction and maintenance of highways, subgrade settlement is a frequent phenomenon of road surface damage, especially on soft soil foundation sections, which seriously affects the driving quality of the highway and the traffic safety of vehicles, and also has a great impact on the operating life of the highway. . Due to its vast territory and complex geological conditions, it puts high demands on the construction and maintenance of highways. In the process of road construction, various factors such as soft foundation, bad soil roadbed, high-fill embankment, steep slope embankment, etc. may lead to roadbed settlement. Complicated and harsh geological conditions and shortening the construction period in order to speed up road construction are also road...

AI Technical Summary

Problems solved by technology

However, the top of the metal measuring rod is exposed to the road surface for a long time, which is easily damaged and affects the accuracy of monitoring.

During the construction process, since the settlement plate needs to be buried in the foundation in advance, it may cause insufficient foundation compaction and affect the quality of the foundation; secondly, in order to avoid damage to the settlement plate, it is necessary to avoid the area where the settlement plate is buried during construction, which affects the progress of the construction; Finally, it is difficult to carry out remedial measures after the settling plate is damaged
