Description

Technical Field

[0001] The utility model relates to the technical field of detection device application, in particular to a layered mark straightening device. Background Art

[0002] The stratified markers are marking points buried in soil layers at different depths. In the ground subsidence area, the stratified markers are buried in soil layers at different depths and directly pass through the ground. After stability protection treatment, they are combined with other stratified markers and bedrock markers to measure the compression and expansion of different soil layers, thereby calculating the deformation of different soil layers.

[0003] The ground subsidence stratification mark is a device for measuring the ground stratification and settlement. The existing technology is to install multiple stabilizers at different depths on the stratification mark pole. As the ground subsidence occurs, the ground stratification pole will continue to be higher than the ground, and the stabilizer on the top of the stratification mark will be higher than the stratification mark protection tube, causing the stabilizer on the top of the stratification mark to fail and the stratification mark pole to tilt, which will cause errors when conducting leveling measurements on the mark head. Due to the continuous occurrence of ground subsidence, the stratification mark head will continue to be higher than the ground, and as the monitoring time increases, the height of the mark head above the ground will become higher and higher, and the degree of inclination of the mark head will also become greater, which will have an increasingly obvious impact on the accuracy of the stratification mark leveling measurement work. Utility Model Content

[0004] The purpose of the utility model is to provide a layered mark straightening device, a manually adjustable straightening structure is set on the layered mark pole, the straightening structure is composed of a retractable triangular straightening frame, a level ruler connected to the triangular foot by a rope, and a level bubble on the top of the layered mark pole, and the tripod is connected to the layered mark pole by an elastic buckle. When in use, the directions of the three level rulers are directly opposite to the directions of the three feet, which are used to indicate whether the layered mark pole is vertical. The direction in which the bubble of the vertical ruler in the level ruler deviates indicates which direction is high, and it is necessary to lower the height of the straightening frame in the corresponding direction until the three vertical rulers indicate that they are all centered and the level bubble placed in the plane at the connection between the layered mark head and the layered mark pole is centered. At this time, it means that the layered mark pole is vertical, and the layered mark leveling work can be carried out. After the leveling work is completed, the device can be removed and installed on other layered mark poles to perform straightening operations. The structure is simple, easy to operate, and can be used multiple times, effectively preventing the failure of the original straightening facilities of the layered mark due to stratum settlement, and improving the accuracy of ground stratified settlement leveling measurement.
