Abstract
Description
Technical Field
[0001] This utility model relates to the field of roadbed settlement monitoring technology, specifically a roadbed settlement monitoring device. Background Technology
[0002] Soft soil subgrade is a special type of subgrade found in rainy areas such as rivers and lakes. Soft soil has high water content and poor permeability. When constructing roads in soft soil subgrade areas, it is necessary to consider the settlement and stability of the subgrade. Therefore, it is necessary to test the water content of the soft soil to determine its properties and better control the subgrade settlement range.
[0003] For example, a roadbed settlement monitoring device with authorization announcement number "CN220818968U" sometimes uses observation holes to monitor the water level of soft soil roadbeds. However, the observation results are not clear enough, leading to problems with the monitoring angle. Furthermore, this type of roadbed settlement monitoring device is prone to displacement of the lifting rod when the buoy floats upwards, resulting in deviations in the monitoring results and reducing the quality of work. Additionally, after monitoring the roadbed settlement, some soil can pass through the filter screen and enter the measuring rod, making it impossible to clean the soil residue inside the measuring rod, thus increasing the limitations of the work. Utility Model Content
[0004] The purpose of this invention is to solve the problems that the lifting rod is prone to deviation when the buoy floats upward, resulting in deviations in the monitoring results and thus reducing the quality of work, and that some soil can pass through the filter screen and enter the measuring rod after monitoring the roadbed settlement, making it impossible to clean the soil inside the measuring rod and thus increasing the limitations of the work. Therefore, a roadbed settlement monitoring device is proposed.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] Design a roadbed settlement monitoring device, including a disc and support rods. Support rods are fixedly connected to both sides of the lower end of the disc. A limiting mechanism is installed on the upper part of the disc. The inner wall of the middle part of the disc is fixedly connected to a tank. The upper end of the tank is in contact with the inner wall of the cover. Disassembly mechanisms are installed on both sides of the cover. A filter screen is provided on the outer wall of the tank.
[0007] Preferably, the limiting mechanism includes a vertical rod, the lower end of which is fixedly connected to a disc, the outer wall of which is connected to a plate, the lower end of which is fixedly connected to the rod, and the inner walls on both sides of the plate are rotatably connected to rollers via bearings.
[0008] Preferably, the outer walls of the rollers are all in contact with the vertical rods, and the upper ends of the vertical rods are all in contact with the sleeve body through rubber rings.
[0009] Preferably, the disassembly mechanism includes a bent plate, the outer wall of which is slidably connected to the cover, the upper end of which is fixedly connected to the block, the outer wall of which is slidably connected to the cover, the inner wall of which is slidably connected to the crossbar, and the inner side of which is fixedly connected to the cover.
[0010] Preferably, the outer wall of each crossbar is provided with a spring, both ends of which are fixedly connected to the cover and the block, the lower side of each bent plate is slidably connected to the support block, and the lower end of each support block is fixedly connected to the disc.
[0011] Preferably, the lower inner wall of the tank is in contact with the buoy, the upper end of the buoy is fixedly connected to a rod, the outer wall of the rod is provided with scale lines, and the upper left side of the cover is fixedly connected to a pointer.
[0012] The roadbed settlement monitoring device proposed in this utility model has the following advantages: through the cooperation of the limiting mechanism and the disc, the plate moves on the vertical rod via rollers during movement. The vertical rod can limit the plate and prevent it from tilting or shifting during movement, thereby preventing the rod from tilting or shifting during movement. The sleeve can prevent the plate from sliding out of the vertical rod when moving upward. In this way, the moving buoy and rod can be limited and prevented from deviating, thereby reducing the deviation of the roadbed settlement monitoring data and improving the quality of work.
[0013] By coordinating the disassembly mechanism and the cover, the two blocks are moved outward, causing the bent plates to move. At this time, the springs are stretched. After the lower sides of the two bent plates separate from the support blocks, the movement of the two blocks stops. Then, the cover is moved upward to separate it from the top of the tank. After the cover separates from the tank, the two blocks are released, and the springs rebound, thereby causing the two bent plates to return to their original positions. By doing so, the limitation of the cover on the tank is removed. Then, the soft mud remaining on the rod, buoy, and tank can be cleaned, thereby reducing the accumulation of soft mud and reducing operational limitations. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings:
[0021] See attached document Figure 1-5 In this embodiment, a roadbed settlement monitoring device includes a disc 1 and support rods 4. Support rods 4 are fixedly connected to both sides of the lower end of the disc 1. A limiting mechanism 2 is installed on the upper part of the disc 1. The inner wall of the middle part of the disc 1 is fixedly connected to the tank 5. The upper end of the tank 5 is attached to the inner wall of the cover 9. Disassembly mechanisms 3 are installed on both sides of the cover 9. A filter screen is provided on the outer wall of the tank 5. The filter screen is made of stainless steel mesh. The lower inner wall of the tank 5 is attached to a buoy 6. The buoy 6 is the same as that in the announcement number "CN220818968U". A rod 7 is fixedly connected to the upper end of the buoy 6. The buoy 6 drives the rod 7 to move. The outer wall of the rod 7 is provided with scale lines. A pointer 8 is fixedly connected to the upper left side of the cover 9.
[0022] See attached document Figure 1-4 The limiting mechanism 2 includes a vertical rod 201. The lower end of the vertical rod 201 is fixedly connected to the disc 1. The outer wall of the vertical rod 201 is slidably connected to the plate 202. The lower end of the plate 202 is fixedly connected to the rod 7. The inner walls on both sides of the plate 202 are rotatably connected to the rollers 203 through bearings. The rollers 203 rotate inside the plate 202. The outer walls of the rollers 203 are in contact with the vertical rod 201. The upper end of the vertical rod 201 is in contact with the sleeve 204 through the rubber ring 205. The rubber ring can increase the friction. The friction between the sleeve 204 and the vertical rod 201 is such that, except for manual movement of the sleeve 204, the sleeve 204 is not easily moved by external influences.
[0023] See attached document Figure 1 , Figure 2 and Figure 5The disassembly mechanism 3 includes a bent plate 301. The outer wall of the bent plate 301 is slidably connected to the cover 9. The bent plate 301 slides inside the cover 9. The upper end of the bent plate 301 is fixedly connected to the block 304. The block 304 drives the bent plate 301 to move. The outer wall of the block 304 is slidably connected to the cover 9. The block 304 slides on the cover 9. The inner wall of the bent plate 301 is slidably connected to the crossbar 302. The bent plate 301 slides on the crossbar 302. The inner side of the crossbar 302 is fixedly connected to the cover 9. The outer wall of the crossbar 302 is provided with a spring 303. The elastic coefficient of the spring 303 can meet the working requirements according to actual needs. Both ends of the spring 303 are fixedly connected to the cover 9 and the bent plate 301. The lower side of the bent plate 301 is slidably connected to the support block 305. The bent plate 301 slides inside the support block 305. The lower end of the support block 305 is fixedly connected to the disc 1.
[0024] Working principle:
[0025] When monitoring roadbed settlement is required, the tank 5 is inserted into the soft soil where the settlement needs to be monitored, and the lower side of the disc 1 is in contact with the soft soil. The disc 1 can contact the surface of the soft soil to prevent the entire device from sinking in the soft soil. The water in the soft soil is filtered through the filter screen on the outer wall of the tank 5 and seeps into the interior of the tank 5 (soft soil larger than the mesh of the filter screen will be blocked outside the mesh, while some soft soil will also enter the tank 5 through the filter screen), while the water in the soft soil will pass through the mesh and enter the tank. As the water level inside the tank 5 rises, the float 6 moves upward along with the water level, which in turn drives the rod 7 to move upward. When the rod 7 moves upward, it also drives the plate 202 to move. During the movement, the plate 202 moves on the vertical rod 201 via the roller 203. The vertical rod 201 can limit the plate 202 to prevent it from tilting or shifting during the movement, and thus prevent the rod 7 from tilting or shifting during the movement. The sleeve 204 can prevent the plate 202 from sliding out of the vertical rod 201 when it moves upward.
[0026] Users can record data by observing the position of the pointer on the scale line of the rod 7. The settlement of the soft soil is determined by measuring the water content of the soft soil in the above way. After the settlement monitoring of the soft soil is completed, the device is removed from the soft soil, thus completing the monitoring of the roadbed settlement of the soft soil. After the device is removed from the soft soil, the water in the tank 5 will flow out of the tank 5 through the filter screen on the tank 5.
[0027] Then, remove the sleeves from the two vertical rods 201. Next, move the two blocks 304 outwards. The blocks 304 move the bent plates 301, at which point the springs 303 are stretched. Stop moving the blocks 304 after the lower sides of the two bent plates 301 separate from the support blocks 305. Then, move the cover 9 upwards to separate it from the top of the can 5. After the cover 9 separates from the can 5, release the two blocks 304. The springs 303 rebound and move the two bent plates 301 back to their original positions. In this way, the limitation of the cover 9 on the can 5 is removed. Then, move the cover 9 upwards and move the plate 202 (cover 9 and plate 20) together. 2. Move upwards together. When the plate 202 moves, it will drive the rod 7 and the buoy 6 to move together until the plate 202 slides off the two vertical rods 201. Then, clean the soft mud remaining on the rod 7, the buoy 6 and the tank 5 respectively. After cleaning the soft mud remaining on the rod 7, the buoy 6 and the tank 5, the cover 9 is fixed on the tank 5 again in the above manner, and the plate 202 is reset on the two vertical rods 201. Finally, the two sleeves 204 are put back on the two vertical rods 201. The cleaning of the soft mud remaining on the rod 7, the buoy 6 and the tank 5 is completed in the above manner, thereby preventing excessive soft mud accumulation.
[0028] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
