Description

Technical Field

[0001] The invention belongs to the technical field of high fill settlement testing, and in particular relates to a high fill settlement testing device and an installation method thereof. Background Art

[0002] High fill is defined as soil with a fill height greater than 18m. According to the fill height, it can be divided into low fill roadbed and high fill roadbed. At present, settlement plates are often used to test the settlement of high fill. However, due to the high height of high fill, the settlement of different soil layers inside it is different. Conventional settlement plates are difficult to test the settlement of deeper soil layers, resulting in the problem of inaccurate test results.

[0003] Combining the above-mentioned problems, we can find that it is difficult to avoid the above-mentioned problems when the existing devices on the market are in use, and thus it is impossible to achieve the desired effect. Therefore, we propose a high fill settlement testing device and its installation method, which can test the settlement of the internal soil layer of the high fill when in use. Summary of the Invention

[0004] The purpose of the present invention is to target an existing high fill settlement testing device, which has the advantage of arranging a casing, a settlement sensing component, a settlement observation component and an installation component. The settlement sensing component is installed inside the high fill at the test location by using the casing. When the soil layer at that location settles, the pressure of the soil layer forces the settlement sensing component to sink and simultaneously drives the settlement observation component to move, so that the settlement amount of the high fill can be obtained by observing the settlement distance of the settlement observation component. The installation component can be used to constrain the settlement sensing component when it is installed, so that it can be installed to the desired location. Therefore, after the installation is completed, the installation component will release the constraint on it, so that it can be adjusted to a working state for easy use.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: a high fill settlement testing device, including a casing, a settlement sensing component, a settlement observation component and an installation component, the settlement sensing component is sleeved on the surface of the casing, the bottom of the settlement observation component is bolted to the top of the settlement sensing component, and the other end of the settlement observation component is at the top inside the casing, the installation component is sleeved on the surface of the settlement sensing component, and the installation component is used in conjunction with the settlement sensing component.

[0006] The above technical solution is adopted, by setting a casing, a settlement sensing component, a settlement observation component and an installation component, and using the casing to install the settlement sensing component inside the high fill at the location to be tested. When the soil layer at this location settles, the pressure of the soil layer forces the settlement sensing component to sink, and simultaneously drives the settlement observation component to move, so that the settlement amount of the high fill can be achieved by observing the settlement distance of the settlement observation component. The installation component can be used to constrain the settlement sensing component during installation, so that it can be installed to the desired location. Therefore, after the installation is completed, the installation component will release the constraint on it, so that it can be adjusted to a working state for easy use.

[0007] The present invention is further configured as follows: the settlement sensing component includes a protective shell, a magnetic ring is placed inside the protective shell, and the magnetic ring is adsorbed on the surface of the casing, the bottom inside the protective shell is connected to a number of connecting blocks in a circular rotation, and the other end of the connecting block is welded with a high-toughness steel sheet.

[0008] By adopting the above technical solution and setting up a settlement sensing component, the pressure when the soil layer settles will be transferred to the high-toughness steel sheet, and simultaneously drive the protective shell to move, thereby overcoming the magnetic attraction between the magnetic ring and the casing, thereby achieving the effect of sensing the soil layer settlement pressure and transferring this pressure conversion to the settlement observation component.

[0009] The present invention is further configured as follows: the settlement observation component includes two connecting parts, the bottom of the connecting part is bolted to the protective shell, and the other end of the connecting part extends to the top of the inside of the casing and is bolted to a synchronization plate, the top of the synchronization plate is bolted to an observation rod, the top of the surface of the observation rod is sleeved with a sealing plate, and the surface of the sealing plate is bolted to the inner wall of the casing, the inside of the sealing plate is bolted with an indicator ring, and the indicator ring is used in conjunction with the observation rod.

[0010] By adopting the above technical solution and setting up a settlement observation component, when the protective shell moves, it will synchronously drive the connecting part to move, so that the connecting part drives the synchronization plate and the observation rod to move, so that the indicator ring can indicate the displacement distance of the observation rod, thereby achieving the effect of intuitively understanding the settlement amount.

[0011] The present invention is further configured as follows: the installation component includes a constraint component, the constraint component is sleeved on the top of the protective shell surface, and is used in conjunction with a high-toughness steel sheet, the left side of the constraint component is bolted with a connecting plate, and a release component is passed through the interior of the connecting plate, and the release component is used in conjunction with the constraint component.

[0012] By adopting the above technical solution, by setting up the installation components, the release component and the constraint component can be used in conjunction with each other, so that when the settlement sensing component has not entered the buried position, the high-toughness steel sheet of the settlement sensing component can be retracted to facilitate the settlement sensing component to enter the hole. After the settlement sensing component is buried to the required position, the positioning of the constraint component can be released by the release component, thereby resetting the constraint component and achieving the effect of restoring the settlement sensing component to the working state.

[0013] The present invention is further configured as follows: the constraint assembly includes a constraint ring, the constraint ring is slidably sleeved on the surface of the protective shell, and the surface of the sleeve is sleeved with a fixed disk, the front and rear sides of the top of the constraint ring are bolted with guide columns, the top of the guide column passes through the interior of the fixed disk, and the surface of the guide column is sleeved with a reset spring, and the reset spring is bolted to the constraint ring and the fixed disk on one side close to the constraint ring and the fixed disk respectively.

[0014] By adopting the above technical solution, a constraint assembly is set up, and the constraint ring moves on the surface of the protective shell, which will contact the connecting block and, under the pressure of the constraint ring, cause multiple connecting blocks to be synchronously retracted. The movement of the constraint ring will also drive the guide column to move, limiting its movement trajectory, and the reset spring is stretched synchronously. With the help of the tension of the reset spring, the constraint ring can be reset, thereby releasing the retraction operation of the high-toughness steel sheet.

[0015] The present invention is further configured as follows: the release assembly includes a sleeve, the sleeve passes through the interior of the connecting plate, and a screw is rotatably connected to the interior of the sleeve, the top and bottom surfaces of the screw are provided with positioning members, the two positioning members are used in conjunction with the connecting plate and the sleeve respectively, the bottom surface of the sleeve is sleeved with a contact ring, and the contact ring is in close contact with the connecting plate;

[0016] The positioning member includes a connecting disk and a screw sleeve, the connecting disk is sleeved on the surface of the screw, the screw sleeve is threadedly connected to the surface of the screw, both sides of the connecting disk are rotatably connected to positioning plates, and the bottom of the positioning plate is rotatably connected to a support rod, and the side of the support rod close to the screw sleeve is rotatably connected to the screw sleeve.

[0017] The above technical solution is adopted, by setting a release component, passing the sleeve through the inside of the connecting plate, and causing the screw to rotate inside the sleeve. At the same time, through the cooperation of the threads of the screw and the sleeve, the sleeve is moved up on the surface of the screw, and the movement will drive the support rod to move synchronously, so that the support rod can adjust the angle of the positioning plate, so that it moves out from the inside of the sleeve and contacts the connecting plate, thereby achieving the effect of positioning the constraint ring. When the screw rotates in the opposite direction, the sleeve can be reset, thereby achieving the effect of releasing the positioning of the constraint ring.

[0018] The present invention is further configured as follows: a fixing plate is bolted to the top of the front side of the sleeve, and the top and bottom positioning plates are in close contact with the fixing plate and the connecting plate respectively.

[0019] By adopting the above technical solution and providing a fixing plate, the sleeve can be positioned.

[0020] The present invention is further configured such that both sides of the top of the protective shell are bolted with limit plates, and the bottoms of the limit plates are in contact with the constraint assembly.

[0021] By adopting the above technical solution, by providing a limit plate, the connection position between the constraint ring and the protective shell can be limited so that the constraint ring will not separate from the protective shell.

[0022] The present invention is further configured such that: the sleeve is composed of a combination of hollow tubes that can be spliced ​​and have a certain thickness and strength, and the outer wall of the sleeve is relatively smooth.

[0023] By adopting the above technical solution, the casing is composed of spliced ​​hollow tubes with a certain thickness and strength, which can be easily buried in high fill at different depths. Moreover, the outer wall of the casing is relatively smooth, which can reduce the friction between the settlement sensing component and the casing and improve the sensing accuracy.

[0024] A method for installing a high fill settlement testing device comprises the following steps:

[0025] S1. Prepare the appropriate number of casings, settlement sensing components, settlement observation components, and installation components according to the high fill settlement test requirements, and place them in sequence near the buried location.

[0026] S2. Measure the specific locations of the corresponding casings according to the designed buried depth of the settlement sensing components. After marking them, insert the settlement sensing components into the corresponding casings and move them to the corresponding locations.

[0027] S3. The constraint assembly is mounted on the settlement sensing component and the elastic structure of the settlement sensing component is constrained to collapse. The release assembly restricts the position of the constraint assembly and the settlement observation component is passed through the constraint assembly to connect it to the settlement sensing component, and its top end is mounted inside the casing;

[0028] S4. Use a drill to drill a hole at the buried settlement test location, ensuring the hole depth is less than the length of the casing and the hole diameter is slightly smaller than the working range of the settlement sensing component. Once the hole is drilled, lower the casing into the hole, allowing the release assembly to release the restraint assembly, resetting the restraint assembly and allowing the settlement sensing component to expand to its working state. Finally, seal the hole with the original soil.

[0029] S5. When high fill settles, the soil pressure forces the settlement sensing component to move downward, and simultaneously drives the settlement observation component to move. Finally, the settlement distance of the settlement observation component is recorded.

[0030] In summary, the present invention has the following beneficial effects:

[0031] By setting up casing, settlement sensing component, settlement observation component and installation component, the settlement sensing component is installed inside the high fill at the location to be tested by using the casing. When the soil layer at that location settles, the pressure of the soil layer forces the settlement sensing component to sink, and simultaneously drives the settlement observation component to move, so that the settlement amount of the high fill can be achieved by observing the settlement distance of the settlement observation component. The installation component can be used to constrain the settlement sensing component during installation, so that it can be installed at the desired location. Therefore, after the installation is completed, the installation component will release the constraint on it, so that it can be adjusted to a working state for easy use.

DETAILED DESCRIPTION

[0041] The present invention will be further described in detail below with reference to the accompanying drawings.

[0042] Example 1:

[0043] refer to Figure 1-7 A high fill settlement test device includes a casing 1, a settlement sensing component 2, a settlement observation component 3 and a mounting component 4. The settlement sensing component 2 is sleeved on the surface of the casing 1, the bottom of the settlement observation component 3 is bolted to the top of the settlement sensing component 2, and the other end of the settlement observation component 3 is at the top inside the casing 1. The mounting component 4 is sleeved on the surface of the settlement sensing component 2, and the mounting component 4 is used in conjunction with the settlement sensing component 2. By setting the casing 1, the settlement sensing component 2, the settlement observation component 3 and the mounting component 4, by using the casing 1 to The settlement sensing component 2 is installed inside the high fill at the location to be tested. When the soil layer at that location settles, the pressure of the soil layer forces the settlement sensing component 2 to sink, and simultaneously drives the settlement observation component 3 to move, so that the settlement amount of the high fill can be achieved by observing the settlement distance of the settlement observation component 3. The installation component 4 can be set to constrain the settlement sensing component 2 during installation, so that it can be installed at the desired location. Therefore, after the installation is completed, the installation component 4 will release the constraint on it, so that it can be adjusted to a working state for easy use.

[0044] like Figure 3 As shown, the settlement sensing component 2 includes a protective shell 21, a magnetic ring 22 is placed inside the protective shell 21, and the magnetic ring 22 is adsorbed on the surface of the casing 1, and the bottom inside the protective shell 21 is connected to a number of connecting blocks 23 in a circular rotation, and the other end of the connecting block 23 is welded with a high-toughness steel sheet 24. By setting the settlement sensing component 2, when the soil layer settles, the pressure will be transferred to the high-toughness steel sheet 24, and the protective shell 21 will be driven to move synchronously, thereby overcoming the magnetic attraction between the magnetic ring 22 and the casing 1, thereby achieving the effect of sensing the settlement pressure of the soil layer, and converting this pressure to the settlement observation component 3.

[0045] like Figure 4 As shown, the settlement observation component 3 includes two connecting parts 31, the bottom of the connecting part 31 is bolted to the protective shell 21, and the other end of the connecting part 31 extends to the top of the inside of the casing 1 and is bolted with a synchronization plate 32, the top of the synchronization plate 32 is bolted with an observation rod 33, the top of the surface of the observation rod 33 is sleeved with a sealing plate 34, and the surface of the sealing plate 34 is bolted to the inner wall of the casing 1, the inside of the sealing plate 34 is bolted with an indicator ring 35, and the indicator ring 35 is used in conjunction with the observation rod 33. By setting the settlement observation component 3, when the protective shell 21 moves, it will synchronously drive the connecting part 31 to move, so that the connecting part 31 drives the synchronization plate 32 and the observation rod 33 to move, so that the indicator ring 35 can indicate the displacement distance of the observation rod 33, thereby achieving the effect of intuitively understanding the settlement amount.

[0046] like Figure 1 As shown, the installation component 4 includes a constraint component 41, which is sleeved on the top of the surface of the protective shell 21 and is used in conjunction with the high-toughness steel sheet 24. A connecting plate 43 is bolted to the left side of the constraint component 41, and a release component 42 is passed through the interior of the connecting plate 43. The release component 42 is used in conjunction with the constraint component 41. By setting the installation component 4, the release component 42 and the constraint component 41 can be used in conjunction to retract the high-toughness steel sheet 24 of the settlement sensing component 2 when the settlement sensing component 2 has not entered the buried position, so as to facilitate the settlement sensing component 2 to enter the formed hole. After the settlement sensing component 2 is buried to the desired position, the release component 42 can be used to release the positioning of the constraint component 41, thereby resetting the constraint component 41 and achieving the effect of restoring the settlement sensing component 2 to the working state.

[0047] like Figure 5 As shown, the constraint assembly 41 includes a constraint ring 411, which is slidably sleeved on the surface of the protective shell 21, and a fixed disk 412 is sleeved on the surface of the sleeve 1. The front and rear sides of the top of the constraint ring 411 are bolted with guide posts 413, and the top of the guide post 413 passes through the interior of the fixed disk 412. A reset spring 414 is sleeved on the surface of the guide post 413, and the reset spring 414 is bolted to the constraint ring 411 and the fixed disk 412 on one side. By setting up a constraint component 41, the constraint ring 411 moves on the surface of the protective shell 21, which will contact the connecting block 23, and under the pressure of the constraint ring 411, the multiple connecting blocks 23 will be synchronously retracted. The movement of the constraint ring 411 will also drive the guide column 413 to move, limiting its movement trajectory, and the reset spring 414 will be stretched synchronously. With the help of the tension of the reset spring 414, the constraint ring 411 can be reset, thereby releasing the retraction operation of the high-toughness steel sheet 24.

[0048] like Figure 6 and Figure 7As shown, the release assembly 42 includes a sleeve 421, which passes through the interior of the connecting plate 43 and is rotatably connected to a screw 422. Positioning members 423 are provided on the top and bottom of the surface of the screw 422. The two positioning members 423 cooperate with the connecting plate 43 and the sleeve 1 respectively. A contact ring 424 is sleeved on the bottom of the surface of the sleeve 421, and the contact ring 424 is in close contact with the connecting plate 43.

[0049] The positioning member 423 includes a connecting plate 4231 and a screw sleeve 4232. The connecting plate 4231 is sleeved on the surface of the screw 422. The screw sleeve 4232 is threadedly connected to the surface of the screw 422. Both sides of the connecting plate 4231 are rotatably connected to the positioning plate 4233, and the bottom of the positioning plate 4233 is rotatably connected to the support rod 4234. The side of the support rod 4234 close to the screw sleeve 4232 is rotatably connected to the screw sleeve 4232. By setting the release component 42, the sleeve 421 passes through the interior of the connecting plate 43, and the screw 422 is released. The internal rotation of the sleeve 421 and the threaded cooperation between the screw 422 and the screw sleeve 4232 cause the screw sleeve 4232 to move up on the surface of the screw 422. The movement will also drive the support rod 4234 to move synchronously, so that the support rod 4234 can adjust the angle of the positioning plate 4233, so that it can move out from the inside of the sleeve 421 and contact with the connecting plate 43, thereby achieving the effect of positioning the constraint ring 411. When the screw 422 rotates in the opposite direction, the screw sleeve 4232 can be reset, thereby achieving the effect of releasing the positioning of the constraint ring 411.

[0050] like Figure 1 As shown, a fixing plate 5 is bolted to the top of the front side of the sleeve 1, and the top and bottom positioning plates 4233 are in close contact with the fixing plate 5 and the connecting plate 43 respectively. By setting the fixing plate 5, the position of the sleeve 421 can be positioned.

[0051] like Figure 1 As shown, both sides of the top of the protective shell 21 are bolted with limit plates 6, and the bottom of the limit plates 6 is in contact with the constraint assembly 41. By setting the limit plates 6, the connection position of the constraint ring 411 and the protective shell 21 can be limited so that it will not detach from the protective shell 21.

[0052] like Figure 1 As shown, the casing 1 is composed of hollow tubes that can be spliced ​​together and have a certain thickness and strength, and the outer wall of the casing 1 is relatively smooth. By setting the casing 1 to be composed of hollow tubes that can be spliced ​​together and have a certain thickness and strength, it can be easily buried in high fills of different depths, and the outer wall of the casing 1 is relatively smooth, which can reduce the friction between the settlement sensing component 2 and the casing 1 and improve the sensing accuracy.

[0053] The use process is briefly described as follows: the settlement sensing component 2 is put into the corresponding sleeve 1 and moved to the corresponding position, and then the sleeve 421 passes through the fixed plate 5 and the connecting plate 43, and pushes the constraint ring 411 to move, so that it drives the guide column 413 to move and stretch the reset spring 414, and the constraint ring 411 will contact the connecting block 23 during the movement, and under the pressure of the constraint ring 411, the multiple connecting blocks 23 are synchronously retracted, and then the screw rod 422 is rotated inside the sleeve 421, and at the same time, the screw sleeve 4232 is moved up on the surface of the screw rod 422 through the threaded cooperation between the screw rod 422 and the screw sleeve 4232, and the movement will drive the support rod 4234 to move synchronously, so that the support rod 4234 can adjust the angle of the positioning plate 4233, so that it can move out from the inside of the sleeve 421 and contact with the connecting plate 43 and the fixed plate 5, adjusting the position of the constraint ring 411. The protective shell 21 is fixed in the position, and then connected to the protective shell 21 through the bottom of the connecting piece 31, and the other end is connected to the synchronous plate 32 in the casing 1. After the installation is completed, the casing 1 is lowered into the hole, and the screw sleeve 4232 is reset by rotating the screw rod 422 in the opposite direction, so that the positioning plate 4233 releases the positioning of the constraint ring 411, and under the tension of the reset spring 414, the constraint ring 411 is reset, so that the high-toughness steel sheet 24 can be restored to the working state, and the pressure when the soil layer settles will transmit the pressure to the high-toughness steel sheet 24, and synchronously drive the protective shell 21 to move, thereby overcoming the magnetic attraction between the magnetic ring 22 and the casing 1, so that the protective shell 21 synchronously drives the connecting piece 31 to move, and drives the synchronous plate 32 and the observation rod 33 to move, so that the indicator ring 35 can indicate the displacement distance of the observation rod 33, thereby achieving the effect of intuitively testing the settlement amount.

[0054] like Figure 8 As shown, the present invention also provides a method for installing a high fill settlement testing device, comprising the following steps:

[0055] S1. Prepare the appropriate number of casings 1, settlement sensing components 2, settlement observation components 3, and installation components 4 according to the high fill settlement test requirements, and place them in sequence near the buried location.

[0056] S2. According to the design depth of the settlement sensing component 2, measure and install it in the corresponding specific position of the casing 1, mark the settlement sensing component 2 into the corresponding casing 1 and move it to the corresponding position;

[0057] S3. Fit the constraint assembly 41 onto the settlement sensing component 2 and constrain the elastic structure of the settlement sensing component 2 to collapse it. Position the release assembly 42 to restrict the constraint assembly 41. Insert the settlement observation component 3 through the constraint assembly 41 to connect it to the settlement sensing component 2, with its top end mounted inside the casing 1.

[0058] S4. Drill a hole at the buried settlement test location using a drill rig. The hole depth is less than the length of the casing 1, and the hole diameter is slightly smaller than the operating range of the settlement sensing component 2. After drilling is complete, the casing 1 is lowered into the hole, and the release assembly 42 releases the restraint assembly 41, allowing the restraint assembly 41 to reset and expand the settlement sensing component 2 to its operating position. Finally, the hole is sealed with the original soil.

[0059] S5. When the high fill settles, the soil pressure forces the settlement sensing component 2 to move downward, and simultaneously drives the settlement observation component 3 to move, and finally records the settlement distance of the settlement observation component 3.

[0060] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.

10. A method for installing a high fill settlement testing device, characterized in that: The following steps are involved: S1. Prepare a corresponding number of casings (1), settlement sensing components (2), settlement observation components (3), and installation components (4) according to the requirements of the high fill settlement test, and place the casings (1), settlement sensing components (2), settlement observation components (3), and installation components (4) in sequence near the buried location; S2. According to the design depth of the settlement sensing component (2), measure the specific position of the corresponding casing (1) installed in turn, mark the settlement sensing component (2) and put it into the corresponding casing (1) and move it to the corresponding position; S3. The constraint assembly (41) is mounted on the settlement sensing component (2), and the elastic structure of the settlement sensing component (2) is constrained to be collapsed. The release assembly (42) is used to limit the position of the constraint assembly (41), and the settlement observation component (3) is passed through the constraint assembly (41) to be connected to the settlement sensing component (2), and the top end thereof is installed inside the casing (1); S4. A drilling machine is used to drill a hole at the buried settlement test location, and the hole depth is less than the length of the casing (1), and the hole diameter is slightly smaller than the working range of the settlement sensing component (2). After the hole is completed, the casing (1) is lowered into the hole, and the release component (42) releases the positioning of the constraint component (41), so that the constraint component (41) can be reset, and the settlement sensing component (2) can be expanded to the working state. Finally, the hole is sealed with the original soil; S5. When the high fill settles, the soil pressure forces the settlement sensing component (2) to move downward, and simultaneously drives the settlement observation component (3) to move, and finally records the settlement distance of the settlement observation component (3).
