Description

Technical Field

[0001] This invention relates to the field of roadbed construction technology, and in particular to a roadbed settlement monitoring and control device. Background Technology

[0002] Subgrade settlement is a common problem in road engineering, and its causes are complex, usually resulting from the combined effects of geological conditions, construction quality, external loads, and environmental factors. In subgrade settlement remediation, laying geosynthetics (such as geogrids and geotextiles) is an effective reinforcement method, which can improve the overall integrity of the subgrade, distribute loads, and reduce uneven settlement. In existing technologies, subgrade settlement is monitored using subgrade settlement monitoring devices. When settlement is detected, the settlement area is marked, and then geosynthetics are laid manually. During this process, to ensure the geosynthetics are firmly laid, workers need to use U-shaped anchors to anchor the edges of the geosynthetics to the ground; the entire laying process is labor-intensive and inefficient. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a roadbed settlement monitoring and control device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A roadbed settlement monitoring and control device includes a main support frame, a settlement monitor mounted on the lower side of the main support frame, and a settlement control component mounted on the main support frame. The settlement control component includes a fixed beam fixed to the main support frame, two vertical beams fixedly connected to the lower side of the fixed beams, a rotating shaft rotatably connected between the two vertical beams, a roller fixedly connected to the rotating shaft, and a geosynthetic mesh roll provided on the outer side of the roller. When the settlement monitor detects roadbed settlement, the geosynthetic mesh roll is spread on the settlement area of ​​the roadbed through the roller, thereby achieving the control of roadbed settlement.

[0006] Preferably, grooving devices are symmetrically provided on the fixed beam. The grooving device includes a sliding seat, which slides back and forth in a groove on the fixed beam. A push-pull device is installed on the fixed beam to drive the sliding seat to slide back and forth in the groove. A flat plate is provided on the upper side of the sliding seat, and a grooving tool is installed on the flat plate.

[0007] Preferably, a column is fixedly connected to the sliding seat, the plate can slide up and down along the column, a first spring is installed between the plate and the sliding seat, a first motor is installed on the column, a cam is installed on the main shaft of the first motor, and the cam contacts the plate.

[0008] Preferably, the grooving device includes a base pipe, which is fixed to a flat plate. The base pipe is inclined and has a shovel at its lower end. An auger is rotatably connected inside the base pipe. A second motor is installed at one end of the base pipe to drive the auger to rotate. A soil discharge pipe is provided on one side of the base pipe.

[0009] Preferably, a flattening device is installed on one side of the flat plate. The flattening device includes a base plate, which is fixed to the flat plate by a connecting rod. Two upright plates are fixedly connected to the lower side of the base plate. Each upright plate has a vertically arranged guide groove on one side. A guide block is slidably connected in each guide groove. A flattening roller is rotatably connected between the two guide blocks. A second spring is fixedly connected between the upright plate and the top of the guide groove.

[0010] Preferably, a grooving device is provided between the flattening roller and the roller shaft. The grooving device includes a connecting ring, which is sleeved on the outside of the rotating shaft and can rotate around the rotating shaft. A fixing rod is fixedly connected to the connecting ring. One end of the fixing rod is rotatably connected to the pressure wheel. A third spring is fixedly connected to one side of the fixing rod. One end of the third spring is fixedly connected to a transition plate. The transition plate is fixed to the connecting rod.

[0011] The beneficial effects of the present invention are as follows: When the roadbed settlement monitoring and treatment device provided by the present invention detects the existence of roadbed settlement, it can automatically unfold the geosynthetic mesh roll and lay it on the settlement area of ​​the roadbed. After the laying is completed, it can also effectively reinforce the unfolded geosynthetic mesh roll and effectively prevent the unfolded geosynthetic mesh roll from being blown away by the wind.

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0021] like Figures 1-8 As shown, this embodiment of a roadbed settlement monitoring and control device includes a main support 1, which is directly connected to a tractor during use. A settlement monitor 11 is installed on the lower side of the main support 1. The settlement monitor 11 is a prior art device and is used to monitor whether the roadbed has settled.

[0022] The main support 1 is also equipped with a settlement control component, which includes a fixed beam 2 fixed to the main support 1. Two vertical beams 21 are fixedly connected to the lower side of the fixed beam 2, and a rotating shaft 4 is rotatably connected between the two vertical beams 21. A third motor 40 is installed on one side of one of the vertical beams 21, which drives the rotating shaft 4 to rotate. A roller 41 is fixedly connected to the rotating shaft 4, and a geosynthetic mesh roll 5 is installed on the outside of the roller 41. How the geosynthetic mesh roll 5 is installed on the roller 41 is also existing technology and will not be described in detail here. In use, the settlement monitor 11 monitors whether the roadbed has settled. When the settlement monitor 11 detects that the roadbed 100 has settled, the third motor 40 drives the rotating shaft 4 and the roller 41 to rotate. The rotation of the roller 41 causes the geosynthetic mesh roll 5 to open, thereby opening and spreading the geosynthetic mesh roll 5 to the settled area of ​​the roadbed, thus achieving the treatment of roadbed settlement.

[0023] To ensure a more secure installation of the geosynthetic mesh roll 5 and prevent it from shifting due to wind immediately after installation, this embodiment includes symmetrically arranged grooving devices on the fixed beam 2. Each grooving device includes a sliding seat 23 that slides reciprocally within a groove 22 on the fixed beam 2. A push-pull device 24, which is an electric telescopic rod, is mounted on the fixed beam 2 to drive the sliding seat 23 to slide reciprocally within the groove 22. A flat plate 26 is located on the upper side of the sliding seat 23, and a grooving device 8 is mounted on the flat plate 26. The grooving device 8 includes a base pipe 81, which is fixed to the flat plate 26. The base pipe 81 is inclined and has a blade 84 at its lower end. An auger is rotatably connected inside the base pipe 81. A second motor 83 is mounted at one end of the base pipe 81 to drive the auger to rotate. A soil discharge pipe 82 is located on one side of the base pipe 81. A flexible hose can be installed on the soil discharge pipe 82. When the shovel 84 shovels out the trench 200, the soil produced is piled up at the lower end of the base pipe 81 and gradually transported away by the auger. The soil is discharged from the soil discharge pipe 82. Specifically, the soil can be guided by the flexible hose to the trench 200 after the geosynthetic mesh roll 5 is laid, and the soil can press down the unfolded geosynthetic mesh roll 5.

[0024] A column 25 is fixedly connected to the sliding seat 23. The plate 26 can slide up and down along the column 25. A first spring is installed between the plate 26 and the sliding seat 23. A first motor 27 is installed on the column 25. A cam 28 is installed on the main shaft of the first motor 27. The cam 28 contacts the plate 26. The first motor 27 drives the cam 28 to rotate. Under the action of the cam 28, the plate 26 moves up and down intermittently. In this way, when the trench 200 is opened, the plate 26 is subjected to downward pressure intermittently. When subjected to downward pressure, the shovel 84 will also dig deeper. After the trench 200 is opened, there will be multiple deeper grooves at the bottom of the trench 200, that is, the bottom of the trench 200 is uneven. This can increase the contact area between the unfolded geosynthetic mesh roll 5 and the trench 200, and further improve the fixing effect of the unfolded geosynthetic mesh roll 5.

[0025] A pressing device 6 is provided between the pressing roller 70 and the roller 41. A pressing device 7 is installed on one side of the plate 26. The pressing device 7 includes a base plate 72, which is fixed to the plate 26 by a connecting rod 71. Two vertical plates 73 are fixedly connected to the lower side of the base plate 72. Each vertical plate 73 has a vertically arranged guide groove on one side. A guide block 74 is slidably connected in each guide groove. The pressing roller 70 is rotatably connected between the two guide blocks 74. A second spring 75 is fixedly connected between the vertical plate 73 and the top of the guide groove. The pressing device 6 includes a connecting ring 61, which is sleeved on the outside of the rotating shaft 4 and can rotate around the rotating shaft 4. At the same time, the connecting ring 61 can also slide along the rotating shaft 4. A fixing rod 62 is fixedly connected to the connecting ring 61. One end of the fixing rod 62 is rotatably connected to the pressing roller 63. A third spring 64 is fixedly connected to one side of the fixing rod 62. One end of the third spring 64 is fixedly connected to the transition plate 65. The transition plate 65 is fixed to the connecting rod 71. The pressing roller 63 is correspondingly arranged with the groove 200. After the trench 200 is opened, the unfolded geosynthetic mesh roll 5 is pressed into the trench 200 by the pressure roller 63. The soil discharged through the hose is then guided into the trench 200 to press down the unfolded geosynthetic mesh roll 5. The pressure roller 63, through the third spring 64, continuously provides downward pressure to the unfolded geosynthetic mesh roll 5. Simultaneously, the flattening device 7, located behind, passes over the trench 200, compacting the soil within the trench 200 and further improving the stability of the unfolded geosynthetic mesh roll 5. During flattening, the flattening device 7 primarily uses the downward pressure provided by the second spring 75 to the flattening roller 70. However, as the plate 26 moves downward intermittently, it can momentarily provide a burst of overall downward pressure to the flattening device 7. This causes the pressure of the flattening roller 70 on the soil to increase intermittently and momentarily, further enhancing the stability of the unfolded geosynthetic mesh roll 5.
