Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a dynamic monitoring sensor for the diffusion radius of fluid soil. Background Technology

[0002] Fluidized solidified soil is a new type of soil and rock material that transforms ordinary soil into a highly fluid slurry by adding a solidifying agent. It can be pumped like a liquid and fill various complex spaces, and then hardens into a stable structure. The advantage of fluidized soil is that it has good fluidity, does not require rolling or vibration, and the soil can be excavated on site, construction waste, or recycled construction waste. This not only saves the cost of buying soil, but also the cost of cleaning up the waste, resulting in lower costs.

[0003] After the fluid soil is prepared, its fluidity and diffusion need to be monitored. Currently, in this experiment, the prepared fluid soil is first placed inside a hollow cylinder, and after standing still for a few minutes, the cylinder is moved upwards. The fluid soil then flows and diffuses in all directions. The flow radius is then measured with a measuring ruler to determine the diffusion. However, in actual operation, the inventors found that when the staff moves the cylinder upwards, it cannot be moved vertically, and there is a certain degree of tilt. Therefore, there is a certain error in the diffusion of the fluid soil. At the same time, when measuring the diffusion radius, the measuring ruler needs to be placed above the diffused fluid soil and then measured in mid-air, which introduces a certain error. Existing experimental sites are generally conducted in the open air, in an outdoor environment with normal temperature. When the fluid soil is backfilled into low-temperature environments such as karst caves, the prepared fluid soil may not be able to adapt to the environment, resulting in poor fluidity and poor backfilling effect. Therefore, to address the above problems, a dynamic monitoring sensor for the diffusion radius of fluid soil is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a dynamic monitoring sensor for the diffusion radius of fluid soil to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] As an optional solution of the dynamic monitoring sensor for the diffusion radius of fluidized soil described in this invention, the dynamic monitoring sensor for the diffusion radius of fluidized soil includes a fluidized soil diffusion radius measurement module;

[0007] The top of the fluid soil diffusion radius measurement module is equipped with a fixing sleeve, and an experimental platform for conducting diffusion radius experiments on fluid soil is fixedly connected above the fixing sleeve. A fluid soil container is set above the experimental platform to hold the fluid soil.

[0008] The top of the fluid soil container is fixedly connected to an iron ring. The outside of the fluid soil container is also equipped with a fluid soil temperature control module for regulating the temperature of the fluid soil inside the container. The other end of the fluid soil temperature control module is fixedly connected to a support disc. An L-shaped frame is fixedly connected to the side of the support disc. The other end of the L-shaped frame is fixedly connected to the fluid soil diffusion radius measurement module.

[0009] A hydraulic rod is fixedly connected to the center of the bottom of the supporting disc, and an electromagnet disc is fixedly connected to the free end of the hydraulic rod.

[0010] Below the supporting disc, there is also a fluid soil velocity monitor with a circular trajectory, used to monitor the diffusion rate of fluid soil.

[0011] After the fluidized soil is prepared, its fluidity and diffusion need to be monitored. Currently, in this experiment, the prepared fluidized soil is first placed inside a hollow cylinder. After remaining still for a few minutes, the cylinder is moved upwards, and the fluidized soil flows and diffuses in all directions. The flow radius is then measured using a measuring ruler to determine the diffusivity. However, the inventors found in practice that when the cylinder is moved upwards by hand, it cannot be moved vertically; there is a certain degree of tilt. Therefore, there is a certain error in the diffusion of the fluidized soil. Furthermore, when measuring the diffusion radius, the measuring ruler needs to be placed above the diffused fluidized soil for a suspended measurement, which introduces further measurement errors. Existing experimental sites are generally conducted outdoors in a normal temperature environment. When the fluidized soil is backfilled into low-temperature environments such as karst caves… In some cases, the prepared fluidized soil may not be able to adapt to the environment, resulting in poor fluidity and poor backfilling effect. By setting an iron ring above the fluidized soil container, when the fluidized soil is poured into the container and left to stand for a period of time, the hydraulic rod drives the electromagnet plate to move down, and the electromagnet plate contacts the iron ring. Then, the electromagnet plate is energized to attract the iron ring, and the hydraulic rod is activated to quickly move the electromagnet plate up, ensuring that the iron ring and the fluidized soil container move vertically upward, ensuring that the fluidized soil diffuses naturally and ensuring accurate monitoring of subsequent data. Multiple fluidized soil flow velocity monitors are set on the surface of the support disc. The fluidized soil flow velocity monitors can monitor the flow radius of the fluidized soil in a timely manner. The flow velocity can be calculated from the radius and the flow time of the fluidized soil, which is convenient for subsequent use.

[0012] As an optional solution of the dynamic monitoring sensor for the diffusion radius of fluid soil described in this invention, the fluid soil diffusion radius measurement module includes a horizontally arranged counterweight base, an inner tube and an outer tube arranged in an inner and outer manner fixedly connected above the counterweight base, a fixed sleeve on the top of the inner tube, and an experimental platform fixedly connected to the top of the fixed sleeve.

[0013] The upper side of the counterweight base is also fixedly connected to the L-shaped frame;

[0014] A rotating ring is installed above the outer tube, and connecting frames are fixedly connected to both sides of the rotating ring. A rangefinder is fixedly connected to the other end of each connecting frame.

[0015] As an optional solution of the dynamic monitoring sensor for the diffusion radius of fluid soil described in this invention, a rotating cylinder is provided inside the outer tube, the top of the rotating cylinder is fixedly connected to the rotating ring, a motor is fixedly connected above the counterweight base, a drive gear is fixedly connected to the end of the motor's main shaft, a gear ring meshes with the outer side of the drive gear, and the outer side of the gear ring is fixedly connected to the inner wall of the rotating cylinder.

[0016] As an optional solution for the dynamic monitoring sensor for the diffusion radius of fluid soil described in this invention, a support ring is fixedly connected to the inner side of the outer tube, and the inner side of the support ring is embedded in the rotating cylinder and slidably connected to the rotating cylinder.

[0017] As an optional solution for the dynamic monitoring sensor for the diffusion radius of fluid soil described in this invention, the number of rangefinders is two sets, which are symmetrically arranged about the center of the experimental platform, and the rangefinders are located above the experimental platform.

[0018] When measuring the radius of fluid soil, the distance measuring instruments on both sides move the diffused fluid soil along a circular trajectory. A motor drives the drive gear to rotate, which in turn drives the gear ring to rotate. The gear ring drives the rotating cylinder to rotate at a constant speed, which in turn drives the rotating ring above to rotate. The rotating ring then drives the connecting frames on both sides and the distance measuring instruments to rotate at a constant speed. This allows the distance measuring instruments to measure various parts of the diffused fluid soil. Values ​​can be taken in segments to ensure the accuracy of the fluid soil diffusion radius.

[0019] As an optional solution for the dynamic monitoring sensor for the diffusion radius of fluid soil described in this invention, the fluid soil temperature control module includes a refrigeration device fixedly connected to a supporting disc. The air supply end of the refrigeration device is connected to an air pipe, and the other end of the air pipe is connected to a cold air channel. A covering cylinder is fixedly connected to the outside of the cold air channel, and the inside of the covering cylinder is fixedly connected to the fluid soil container.

[0020] As an optional solution for the dynamic monitoring sensor for the diffusion radius of fluid soil described in this invention, the cold air channel is spirally arranged inside the covering cylinder, and the other end of the cold air channel is open to directly discharge the cold air to the outside of the device.

[0021] As an optional solution for the dynamic monitoring sensor for the diffusion radius of fluid soil described in this invention, the covering cylinder is made of heat dissipation aluminum sheet.

[0022] When using fluid soil, its diffusion radius varies depending on the environment. Therefore, a fluid soil temperature control module is installed on the outside of the fluid soil container. Cold air is supplied to the air pipe through a refrigeration device, and the temperature of the fluid soil inside the container is adjusted through a spiral cold air channel to simulate the environment in which the fluid soil is located, so as to obtain more accurate measurement data.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] By setting an iron ring above the fluid soil container, when the fluid soil is poured into the container and left to stand for a period of time, the hydraulic rod drives the electromagnet plate to move downwards. The electromagnet plate contacts the iron ring, and then the electromagnet plate is energized to attract the iron ring. Activating the hydraulic rod can quickly drive the electromagnet plate upwards, ensuring that the iron ring and the fluid soil container move vertically upwards, ensuring that the fluid soil diffuses naturally, and ensuring accurate monitoring of subsequent data.

[0025] When measuring the radius of fluid soil, the distance measuring instruments on both sides move the diffused fluid soil along a circular trajectory. A motor drives the drive gear to rotate, which in turn drives the gear ring to rotate. The gear ring drives the rotating cylinder to rotate at a constant speed, which in turn drives the rotating ring above to rotate. The rotating ring then drives the connecting frames on both sides and the distance measuring instruments to rotate at a constant speed. This allows the distance measuring instruments to measure various parts of the diffused fluid soil. Values ​​can be taken in segments to ensure the accuracy of the fluid soil diffusion radius.

[0026] Multiple sets of fluid soil velocity monitoring instruments are installed on the surface of the support disc. The fluid soil velocity monitoring instruments can monitor the flow radius of the fluid soil in a timely manner. The flow velocity can be calculated by the radius and the flow time of the fluid soil, which is convenient for subsequent use.

[0027] When using fluid soil, its diffusion radius varies depending on the environment. Therefore, a fluid soil temperature control module is installed on the outside of the fluid soil container. Cold air is supplied to the air pipe through a refrigeration device, and the temperature of the fluid soil inside the container is adjusted through a spiral cold air channel to simulate the environment in which the fluid soil is located, so as to obtain more accurate measurement data.

[0034] Example 1: Please refer to Figure 1 , Figure 3 and Figure 5 The present invention provides a technical solution:

[0035] A dynamic monitoring sensor for the diffusion radius of fluidized soil includes a fluidized soil diffusion radius measurement module 1;

[0036] A fixed sleeve 10 is installed on the top of the fluid soil diffusion radius measurement module 1. An experimental platform 2 for conducting diffusion radius experiments on fluid soil is fixedly connected above the fixed sleeve 10. A fluid soil container 7 for holding fluid soil is set above the experimental platform 2.

[0037] An iron ring 8 is fixedly connected to the top of the fluid soil container 7. A fluid soil temperature control module 9 for regulating the temperature of the fluid soil inside the fluid soil container 7 is also installed on the outside of the fluid soil container 7. A support disc 4 is fixedly connected to the other end of the fluid soil temperature control module 9. An L-shaped frame 3 is fixedly connected to the side of the support disc 4. The other end of the L-shaped frame 3 is fixedly connected to the fluid soil diffusion radius measurement module 1.

[0038] A hydraulic rod 5 is fixedly connected to the center of the bottom of the supporting disc 4, and an electromagnet disc 6 is fixedly connected to the free end of the hydraulic rod 5.

[0039] Below the supporting disc 4, there is also a fluid soil velocity monitor 11, which is set in a circular trajectory to monitor the diffusion speed of fluid soil.

[0040] After the fluidized soil is prepared, its fluidity and diffusion need to be monitored. Currently, in this experiment, the prepared fluidized soil is first placed inside a hollow cylinder. After remaining still for a few minutes, the cylinder is moved upwards, and the fluidized soil flows and diffuses in all directions. The flow radius is then measured using a measuring ruler to determine the diffusivity. However, the inventors found in practice that when the cylinder is moved upwards by hand, it cannot be moved vertically; there is a certain degree of tilt. Therefore, there is a certain error in the diffusion of the fluidized soil. Furthermore, when measuring the diffusion radius, the measuring ruler needs to be placed above the diffused fluidized soil for a suspended measurement, which introduces some measurement error. Existing experimental sites are generally conducted outdoors in a normal temperature environment. When the fluidized soil is backfilled into low-temperature environments such as karst caves, it may cause the prepared soil to... The existing fluid soil cannot adapt to the environment and has poor fluidity, resulting in poor backfilling effect. By setting an iron ring 8 above the fluid soil container 7, when the fluid soil is poured into the fluid soil container 7 and left to stand for a period of time, the hydraulic rod 5 drives the electromagnet plate 6 to move down, and the electromagnet plate 6 contacts the iron ring 8. Then, the electromagnet plate 6 is energized to attract the iron ring 8. Activating the hydraulic rod 5 can quickly drive the electromagnet plate 6 to move up, ensuring that the iron ring 8 and the fluid soil container 7 move vertically upward, ensuring that the fluid soil diffuses under natural conditions, and ensuring accurate monitoring of subsequent data. Multiple sets of fluid soil flow velocity monitors 11 are set on the surface of the support disc 4. The fluid soil flow velocity monitors 11 can monitor the flow radius of the fluid soil in a timely manner. The flow velocity can be calculated by the radius and the flow time of the fluid soil, which is convenient for subsequent use.

[0041] Also includes the following:

[0042] When measuring the diffusion radius of fluid soil, the experimental platform 2 is installed on top of the inner tube 102, and the fixing sleeve 10 is placed on the outside of the inner tube 102. The experimental platform 2 is set horizontally. Then, the fluid soil container 7 is placed in the center of the experimental platform 2, and fluid soil is poured into the fluid soil container 7. After standing for a period of time, when the fluid soil is poured into a low-temperature environment such as a karst cave, the fluid soil inside the fluid soil container 7 can be cooled by the fluid soil temperature control module 9 to simulate the use environment, determine the fluid soil configuration ratio, and ensure the quality of use of the fluid soil.

[0043] The lateral length of the L-shaped frame 3 is greater than the lateral length of the connecting frame 105, thereby ensuring that the connecting frame 105 can rotate normally and avoiding contact and collision with the L-shaped frame 3.

[0044] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 2Specifically, the fluid soil diffusion radius measurement module 1 includes a horizontally arranged counterweight base 101, an inner tube 102 and an outer tube 103 arranged in an inner and outer manner are fixedly connected above the counterweight base 101, a fixing sleeve 10 is fitted on the top of the inner tube 102, and an experimental platform 2 is fixedly connected to the top of the fixing sleeve 10.

[0045] The upper side of the counterweight base 101 is also fixedly connected to the L-shaped frame 3;

[0046] A rotating ring 104 is provided above the outer tube 103. A connecting frame 105 is fixedly connected to both sides of the rotating ring 104, and a rangefinder 106 is fixedly connected to the other end of the connecting frame 105.

[0047] A rotating cylinder 107 is provided on the inner side of the outer tube 103. The top of the rotating cylinder 107 is fixedly connected to the rotating ring 104. A motor 109 is also fixedly connected above the counterweight base 101. A drive gear 110 is fixedly connected to the end of the main shaft of the motor 109. A gear ring 111 meshes with the outer side of the drive gear 110. The outer side of the gear ring 111 is fixedly connected to the inner wall of the rotating cylinder 107.

[0048] A support ring 108 is also fixedly connected to the inner side of the outer tube 103. The inner side of the support ring 108 is embedded in the rotating cylinder 107 and is slidably connected to the rotating cylinder 107.

[0049] There are two sets of rangefinders 106, which are symmetrically arranged about the center of the experimental platform 2, and the rangefinders 106 are located above the experimental platform 2.

[0050] When measuring the radius of the fluid soil, the motor 109 is started in advance. The motor 109 drives the drive gear 110 to rotate, the drive gear 110 drives the gear ring 111 to rotate, the gear ring 111 drives the rotating cylinder 107 to rotate at a constant speed, the rotating cylinder 107 drives the rotating ring 104 above to rotate, and the rotating ring 104 drives the connecting frame 105 on both sides to rotate at a constant speed. The distance measuring instruments 106 on both sides move along a circular trajectory after the fluid soil has diffused, so that the distance measuring instruments 106 can measure various parts of the fluid soil after diffusion. The values ​​can be taken in segments to ensure the accuracy of the value of the diffusion radius of the fluid soil.

[0051] Also includes the following:

[0052] The counterweight base 101 is relatively heavy, which helps to lower the center of gravity of the device and ensure the stability of the device. When the motor 109 starts, it ensures the stability of the experimental platform 2 above and ensures the natural diffusion of the fluid soil.

[0053] When the rotating cylinder 107 rotates, a support ring 108 is provided on its outer side. The support ring 108 serves to support the rotating cylinder 107 and ensure that the rotating cylinder 107 rotates stably.

[0054] When measuring the radius of fluid soil, since the distance between the infrared rangefinders 106 on both sides is constant, the diameter of the fluid soil after diffusion is obtained by subtracting the data detected by the two sets of rangefinders 106 from the distance between the infrared rangefinders 106 on both sides. Then, half of the diameter of the fluid soil after diffusion is the diffusion radius of the fluid soil. This setting can measure the radius of the fluid soil in various directions after diffusion, and the average value can be taken according to the actual situation.

[0055] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 3 and Figure 4 Specifically, the fluid soil temperature control module 9 includes a refrigeration device 901 fixedly connected to the support disc 4. The air supply end of the refrigeration device 901 is connected to an air pipe 902, and the other end of the air pipe 902 is connected to a cold air channel 904. A covering cylinder 903 is fixedly connected to the outside of the cold air channel 904, and the inside of the covering cylinder 903 is fixedly connected to the fluid soil container 7.

[0056] The cold air passage 904 is spirally arranged inside the covering cylinder 903, and the other end of the cold air passage 904 is open to allow cold air to be directly discharged to the outside of the device.

[0057] The 903 cladding cylinder is made of heat dissipation aluminum fins.

[0058] When using fluid soil, the environment varies. For example, normal tunnel backfilling occurs at room temperature, while backfilling karst caves occurs at lower temperatures. The diffusion radius of fluid soil varies at different temperatures. The choice of fluid soil temperature control module 9 depends on the backfilling situation. When backfilling karst caves or other low-temperature sites, the cooling equipment 901 supplies cold air to the air pipe 902, and the spiral cold air channel 904 adjusts the temperature of the fluid soil inside the fluid soil container 7 to simulate the environment of the fluid soil and obtain more accurate measurement data.

[0059] Also includes the following:

[0060] The cold air channel 904 is spirally arranged on the outside of the covering cylinder 903. The temperature of the fluid soil inside the fluid soil container 7 can be adjusted by the delivery of cold air to simulate the backfill site and ensure the backfill quality of the fluid soil. One end of the cold air channel 904 is in direct contact with the external environment, which facilitates the direct discharge of cold air to the outside and ensures the normal operation of the device. The covering cylinder 903 is made of heat dissipation aluminum fins. The aluminum fins help to exchange heat and adjust the temperature of the fluid soil.
