Description

Technical Field

[0001] This utility model relates to the technical field of roadbed construction settlement monitoring equipment, specifically a settlement monitoring device for rockfill roadbed construction. Background Technology

[0002] When constructing highways in mountainous areas, rock-fill roadbeds are commonly used. Due to the larger voids in rock-fill roadbeds, water can easily seep into the roadbed from slopes or the road surface. Rock-fill roadbeds are prone to settlement due to factors such as the maximum particle size of the fill material, compaction degree, foundation soil settlement deformation, moisture content, and water flow, leading to elevation differences at different locations. These differences can cause road surface undulations, affecting driving comfort and safety. Therefore, timely settlement differential monitoring during the construction of rock-fill roadbeds is essential.

[0003] A prior art application (application number 202311317070.5) describes a differential settlement detection device for rockfill subgrade, comprising two sensing columns connected by a connecting rod. The two ends of the connecting rod are hinged to the two sensing columns. Each sensing column has a walking mechanism at its lower end. A vertically positioned detection disk is located in the middle of the connecting rod. The detection disk includes a circular outer shell, inside which is a circular mounting plate. A ring-shaped wound resistor is mounted on the circular mounting plate. A conductive fixing plate is connected to the circular mounting plate, with its other end connected to the center of the circular outer shell. A rotating conductive plate is rotatably connected to the end of the conductive fixing plate located at the center of the circular outer shell. The rotating conductive plate is in contact with the wound resistor, and a counterweight ball is connected to the lower end of the rotating conductive plate. While the differential settlement detection device for rockfill subgrade described in this invention has advantages such as large detection area, high efficiency, low manual labor, and low cost, its complex structure and relatively low settlement monitoring accuracy are problematic. Utility Model Content

[0004] The purpose of this invention is to provide a settlement monitoring device for rockfill roadbed construction, in order to solve the problems of complex structure and low accuracy of settlement monitoring in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a settlement monitoring device for rockfill roadbed construction, comprising a pole, a monitoring sleeve slidably sleeved on the outside of the pole, a plurality of burial positioning plates being provided at the lower end of the monitoring sleeve via a support base, and the support base and the plurality of burial positioning plates being buried in the rockfill roadbed layer, the upper end of the monitoring sleeve penetrating the roadbed layer, a scale line being provided along the axial direction on the outside of the pole, an upper support plate being provided at the top of the pole, and a monitoring camera being rotatably mounted on the upper support plate near the scale line via a connecting seat and a connecting shaft, and one end of the connecting shaft being connected to a motor via a gear set.

[0006] Furthermore, the gear set includes a driven gear disposed on the outer side of one end of the connecting shaft, and a driving gear meshing with the driven gear is connected to one end of the motor.

[0007] Furthermore, the motor is a miniature stepper motor, and the motor is fixedly mounted on the inner wall of the connecting seat via a base.

[0008] Furthermore, the upright is a metal rod, and the lower end of the upright is provided with a pointed tip.

[0009] Furthermore, the lower outer side of the upright is provided with multiple barbs, and the barbs are right triangular plates.

[0010] Furthermore, a storage trough is provided on the inner side of one end of the landfill positioning plate, and a wide extension plate is provided inside the storage trough via a pin.

[0011] Furthermore, the wide plate is a rectangular plate, and two sets of wide plates and pins are symmetrically arranged about the storage slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model inserts the lower end of the upright into the non-settlement layer, and then slides the monitoring sleeve onto the outside of the upright. At the same time, the support base and multiple burial positioning plates outside the monitoring sleeve are buried in the base layer of the stone-filled road. When the base layer of the stone-filled road settles, the monitoring sleeve moves down under the sinking action of the burial positioning plates. The difference in scale between the top of the monitoring sleeve and the outside of the upright is recorded as the settlement value. Moreover, the structure is simple and the settlement monitoring is convenient and quick.

[0014] 2. In this utility model, a monitoring camera is rotatably mounted on the upper support plate near the scale line via a connecting seat and a connecting shaft. One end of the connecting shaft is connected to a motor via a gear set. The gear set includes a driven gear located on the outer side of one end of the connecting shaft, and the other end of the motor is connected to a driving gear meshing with the driven gear. The monitoring camera enables remote observation of settlement monitoring values. Furthermore, the longitudinal angle of the monitoring camera can be adjusted by rotating the connecting shaft driven by the motor and gear set. This allows for real-time video monitoring of the environment near the detection location, improving the functionality of the equipment.

[0015] 3. This utility model has a storage trough on the inner side of one end of the landfill positioning plate, and a wide extension plate is rotatably provided inside the storage trough via a pin. The wide extension plate is a rectangular plate, and two sets of wide extension plates and pins are symmetrically arranged about the storage trough. This allows the lateral contact area between the landfill positioning plate and the interior of the stone-filled road base to be expanded by rotating the wide extension plate. This facilitates the monitoring sleeve to move down better with the settlement of the stone-filled road base, which is beneficial to improving the accuracy of settlement monitoring.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5In this embodiment of the utility model, a settlement monitoring device for the construction of a rockfill roadbed includes a pole 1, a monitoring sleeve 2 slidably sleeved on the outside of the pole 1, and multiple burial positioning plates 4 provided at the lower end of the monitoring sleeve 2 through a support base 3. The support base 3 and the multiple burial positioning plates 4 are buried in the rockfill roadbed 19. The upper end of the monitoring sleeve 2 penetrates the roadbed layer 20. A scale line 11 is provided along the axial direction on the outside of the pole 1. When the rockfill roadbed 19 settles, the monitoring sleeve 2 moves down under the sinking action of the burial positioning plates 4. The difference in scale between the top of the monitoring sleeve 2 and the outside of the pole 1 is recorded as the settlement value. Moreover, the structure is simple and the settlement monitoring is convenient and quick.

[0025] like Figure 1 and Figure 5 As shown, for the purpose of remote settlement monitoring, an upper support plate 5 is provided at the top of the pole 1. A monitoring camera 17 is rotatably mounted on the upper support plate 5 near the scale line 11 via a connecting seat 12 and a connecting shaft 13. One end of the connecting shaft 13 is connected to a motor 16 via a gear set. The gear set includes a driven gear 14 located on the outer side of one end of the connecting shaft 13. One end of the motor 16 is connected to a driving gear 15 that meshes with the driven gear 14. The motor 16 is a miniature stepper motor, and the motor 16 is fixedly mounted on the inner wall of the connecting seat 12 via a base. The monitoring camera 17 enables remote observation of settlement monitoring values. Furthermore, by driving the connecting shaft 13 to rotate via the motor 16 and the gear set, the longitudinal angle of the monitoring camera 17 can be adjusted, which can be used for real-time video monitoring of the environment near the detection location, thus improving the functionality of the equipment.

[0026] like Figure 1 and Figure 2 As shown, in order to improve the stability of the upright 1 when inserted into the non-settlement layer 18, the upright 1 is also made of metal, and the lower end of the upright 1 is provided with a pointed tip 6, which makes it easy to insert the upright 1 into the non-settlement layer 18. The lower outer side of the upright 1 is also provided with multiple barbs 7, and the barbs 7 are right triangular plates, which makes it easier to improve the stability of the upright 1 when inserted into the non-settlement layer 18.

[0027] like Figure 1 and Figure 4 As shown, in order to expand the lateral contact area between the landfill positioning plate 4 and the interior of the stone-filled road base 19, a storage trough 8 is provided on the inner side of one end of the landfill positioning plate 4. A wide extension plate 9 is rotatably provided inside the storage trough 8 via a pin 10. The wide extension plate 9 is a rectangular plate, and two sets of wide extension plates 9 and pins 10 are symmetrically arranged about the storage trough 8. This allows the lateral contact area between the landfill positioning plate 4 and the interior of the stone-filled road base 19 to be expanded by rotating the wide extension plate 9. This facilitates the monitoring sleeve 2 to move down better with the settlement of the stone-filled road base 19, which is beneficial to improving the accuracy of settlement monitoring. Moreover, the wide extension plate 9 can be completely retracted into the storage trough 8 when not in use, which improves the flexibility of the use of the wide extension plate 9.

[0028] The working principle and usage process of this utility model are as follows: When in use, the lower end of the upright 1 is inserted into the non-settlement layer 18, and then the monitoring sleeve 2 is slidably sleeved on the outside of the upright 1. The support seat 3 and multiple burial positioning plates 4 on the outside of the monitoring sleeve 2 are buried in the stone-filled road base 19. When the stone-filled road base 19 settles, the monitoring sleeve 2 moves down under the sinking action of the burial positioning plates 4. The difference in scale between the top of the monitoring sleeve 2 and the outside of the upright 1 is recorded as the settlement value. Moreover, the structure is simple and the settlement monitoring is convenient and quick.
