Description

Technical Field

[0002] Roadbed deformation can cause damage to the road surface and seriously affect the normal use of the road, while roadbed settlement is an important factor causing roadbed deformation. In order to quickly and timely detect the deformation of the roadbed, relevant staff often use roadbed deformation observation rods.

[0003] The Chinese utility model patent with publication number CN218329966U proposes a roadbed deformation observation rod, including an embedded plate, a connecting tube is fixedly installed on the embedded plate, a measuring rod is detachably installed on the connecting tube, a scale is provided on the measuring rod, a fixed sleeve is provided on one side of the measuring rod, an extension plate is sleeved on the fixed sleeve, a reference sleeve is fixed on the other end of the extension plate, and the reference sleeve is clearance-matched with the measuring rod.

[0004] The above technical solution cooperates between the scale set on the measuring rod, the extension plate on the fixed sleeve and the reference sleeve on the extension plate. The staff only needs to compare the scale aligned with the reference sleeve to observe the roadbed settlement. There is no need for the staff to frequently measure the measuring rod, which not only effectively reduces the workload of the staff, but also improves the accuracy of the staff's judgment on the roadbed deformation. However, in this solution, only the roadbed settlement can be measured by the measuring rod, and the lateral deformation of the roadbed cannot be measured, which has low practicality.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 3 The utility model provides a technical solution: a roadbed deformation and settlement observation device, comprising a fixed column 1, a rotating rod 6 is provided at the top end of the fixed column 1 for limited rotation, a swivel 3 is provided at the bottom end of the fixed column 1 for limited rotation, an observation mechanism is provided on one side of the swivel rod 6 and the swivel 3, the observation mechanism comprises two cross bars 4 and a sliding bar 8, the two cross bars 4 are fixedly installed on one side of the swivel rod 6 and the swivel 3 respectively, a pointer 10 is fixedly provided on the other side of the swivel rod 6, an angle scale 11 is provided on the top end face of the fixed column 1, the pointer 10 is arranged above the angle scale 11, the pointer 10 can be driven by the rotation of the rotating rod 6, the angle scale 11 pointed to by the pointer 10 changes, so that the reverse direction of the lateral deformation of the roadbed can be observed.

[0022] In this embodiment, the fixing column 1 is in a "T" shape, and mounting holes 2 are symmetrically opened inside the bottom end of the fixing column 1. The fixing column 1 can be fixed at a position away from the roadbed through the mounting holes 2.

[0023] In this embodiment, a length scale is provided on the top of the cross bar 4, and a movable plate 5 is slidably provided on the outer side of one end of the two cross bars 4. There are two movable plates 5, and the two movable plates 5 are arranged parallel to each other. A fixed cylinder 7 is fixedly installed between the two movable plates 5, and the sliding rod 8 is slidably arranged inside the fixed cylinder 7. A chassis 9 is fixedly provided at the bottom of the sliding rod 8. A length scale is provided on the surface of the sliding rod 8. The movable plate 5 can slide on the cross bar 4, so that the length scale corresponding to the left end of the movable plate 5 changes, which is convenient for observing the lateral deformation of the roadbed. The sliding rod 8 can be aligned with the roadbed through the chassis 9. The sliding rod 8 can be limited by the fixed cylinder 7, the movable plate 5 and the cross bar 4, and the stability of the sliding rod 8 is improved.

[0024] In this embodiment, the rotating rod 6, the sliding rod 8, the fixing tube 7, the movable plate 5 and the cross bar 4 are all made of stainless steel, which can prevent rust from occurring inside the device and improve the accuracy of observation of the device.

[0025] When using the roadbed deformation and settlement observation device, the chassis 9 is pre-buried and installed at the specified position of the roadbed to be measured, the slide bar 8 is installed inside the fixed cylinder 7, and the fixed column 1 is fixedly installed at a position away from the roadbed corresponding to both sides of the roadbed through the mounting hole 2. The position of the angle scale 11 corresponding to the pointer 10, the position of the length scale on the cross bar 4 corresponding to one end of the movable plate 5, and the position of the length scale on the slide bar 8 corresponding to the top of the fixed cylinder 7 are observed and recorded. When the roadbed settles, the slide bar 8 and the chassis 9 slide downward with the settlement of the roadbed, so that the top end surface of the fixed cylinder 7 corresponds to the position of the angle scale 11 corresponding to the pointer 10, and the length scale on the cross bar 4 corresponding to the top end of the fixed cylinder 7. The length scale changes, which is convenient for observing the settlement of the roadbed. When the roadbed deforms laterally, the roadbed will squeeze the fixed chassis 9 and the slide bar 8. Due to the limitation of the fixed cylinder 7, the chassis 9 and the slide bar 8 drive the fixed cylinder 7 to move laterally. At the same time, the fixed cylinder 7 drives the movable plate 5 and the cross bar 4, the cross bar 4 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the pointer 10, so that the angle scale 11 pointed by the pointer 10 changes. At the same time, the movable plate 5 slides on the cross bar 4, so that the length scale corresponding to the left end of the movable plate 5 changes, which is convenient for observing the lateral deformation of the roadbed and has high practicality.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
