Settlement plate for monitoring roadbed

Abstract

The invention discloses a settlement plate for monitoring a roadbed. The settlement plate comprises a settlement plate body, a water inlet pipe, a water outlet pipe, a communicating pipe and a ventilating pipe, the water outlet pipe comprises a horizontal water outlet pipe A, a horizontal water outlet pipe B and a vertical water outlet pipe communicating the horizontal water outlet pipe A with thehorizontal water outlet pipe B, the horizontal water outlet pipe A and the vertical water outlet pipe are both arranged in the settlement plate body, the horizontal water outlet pipe B is arranged above the water inlet pipe, one end of the horizontal water outlet pipe B and one end of the water inlet pipe are both inserted into the settlement plate body, the water inlet pipe is connected with thehorizontal water outlet pipe A through the communicating pipe; and the ventilating pipe is arranged in the settlement plate body, one end of the ventilating pipe is communicated with the horizontal water outlet pipe A, and other end of the ventilating pipe extends out from one side of the settlement plate body. The settlement plate is excellent in durability and stability and high in measurementaccuracy, the embedding and monitoring processes do not affect the subsequent construction and operation, and the requirement on long-term monitoring is met.

Description

technical field [0001] The invention relates to the technical field of roadbed settlement monitoring equipment, in particular to a settlement plate used for roadbed monitoring. Background technique [0002] The subgrade is the foundation of the road surface and the main body of the road. Its quality directly affects the quality of the entire road surface. In order to ensure the safety and stability of the roadbed and realize the high-speed and stable operation of traffic vehicles, the settlement control of the roadbed becomes the key. [0003] At present, due to the wide monitoring area of ​​the sedimentation plate, it is convenient to set up observation stations flexibly, so it is often used. Utility model patent 201720825566.7 discloses a settling plate for soft ground, including a bottom plate and a steel pipe fixed in the middle of the bottom plate. The settling plate is spirally drilled from the bottom up to facilitate the recovery of the settling plate. However, the ...

Utility model patent 201720825566.7 discloses a settling plate for soft ground, including a bottom plate and a steel pipe fixed in the middle of the bottom plate. The settling plate is spirally drilled from the bottom to facilitate the recovery of the settling plate. However, the repeated measurement of the settling plate of this structure is heavy, it is difficult to realize automatic observation, and it interferes a lot with the construction. Deviation due to rolling affects the accuracy of measurement
