Description

Technical Field

[0001] The utility model belongs to the technical field of high fill roadbed construction, and in particular relates to a high fill roadbed settlement observation device for a highway. Background Art

[0002] During the construction of high-fill roadbed, settlement observation can be used to timely understand the deformation of the roadbed and predict future development trends, so as to take necessary measures to ensure construction safety and roadbed stability.

[0003] In order to facilitate the observation of the settlement of the roadbed, it is usually necessary to set up an observation device on the top of the roadbed to assist the observation. In the prior art, the Chinese utility model patent document with the authorization announcement number CN214333757U discloses a new type of highway roadbed settlement observation device. When observing, first select a monitoring point to set up the device, connect the cap of the reflective rope to the top of the settlement pipe thread and tighten it, stretch the settlement pipe to a certain height through the reflective rope, carry out the first layer of filling, read the scale on the outer wall of the settlement pipe and measure the elevation with a level, compress the top of the settlement pipe to the filling point, and then the settlement pipe is tightened. After the soil height is reached, the roller performs normal rolling construction. After the rolling is completed, the cap is found through the reflective rope, and the settlement tube is stretched to a certain height again through the reflective rope. The elevation of the settlement tube is measured, and the second layer of backfill is carried out. The settlement tube is compressed to the same level as the backfill, and the roller performs the second layer of rolling. The above steps are repeated for multiple layers of backfill; as the backfill height increases, the settlement tube can be stretched upward, and adjacent settlement tubes are fixed by friction. During the construction process, due to vibration and other reasons, the settlement tubes are prone to loosening and shrinking, thereby affecting the accuracy of observation.

[0004] Therefore, it is necessary to design a highway high fill roadbed settlement observation device that can lock the settlement tubes, is not easy to loosen, and ensures the accuracy of observation to solve the current technical problems. Summary of the Invention
