Description

Technical Field

[0001] This invention relates to the field of drainage board laying technology, and in particular to an auxiliary device and construction method for laying drainage boards using a tearable membrane vacuum pre-compression method. Background Technology

[0002] With the increasing demand for infrastructure land in coastal cities, the development and utilization of soft foundations with low water content and low strength has become particularly important. These foundations typically exhibit poor permeability, high compressibility, and low bearing capacity, posing significant challenges to construction projects. To effectively address these soft foundations, various technologies and methods have been employed. Currently, the main methods for soft foundation treatment include surcharge preloading, electro-osmosis reinforcement, and vacuum preloading.

[0003] Surcharge preloading increases the pore water pressure in the soil by applying a preload, causing the pore water to drain out. As the pore water pressure gradually dissipates, the effective stress increases, thereby increasing the soil's strength and stability. Electroosmosis reinforcement involves inserting metal electrodes into the soil and applying direct current. Under the influence of the electric field, the negative charge on the surface of soil particles increases, making it easier for water molecules and cations to be attracted to the surface, forming a fixed layer—a strongly bound water layer—while water molecules in the weakly bound water layer are expelled, thus reinforcing the soil. Vacuum preloading involves burying drainage boards in the soil, laying a sand cushion layer and a sealing membrane on the ground, and using a vacuum device to remove air, creating a pressure difference between the inside and outside of the drainage board and membrane. The pore water pressure continuously dissipates, and the effective stress increases, thus reinforcing the soil. Vacuum preloading is widely used in ports, docks, airports, and industrial and civil buildings due to its advantages of short construction period, high safety, environmental friendliness, and relatively low cost.

[0004] In existing vacuum preloading drainage consolidation technology, drainage boards often bend during the vacuum preloading process as the foundation continuously drains and consolidates. Studies have shown that bending of the drainage boards makes them more prone to clogging, significantly reducing drainage efficiency. To address this issue, a membrane-tearing technique is used to tear off a portion of the drainage board's outer membrane and bury the torn portion in the sand layer, increasing friction in the soil and thus mitigating bending. However, in current engineering practice, the membrane-tearing process is generally performed by workers, which leads to problems such as inaccurate tearing height and low efficiency.

[0005] Therefore, there is an urgent need to provide an auxiliary device and construction method for laying drainage boards using the tearable film vacuum pre-compression method, which can improve the accuracy of the tearing height and the tearing efficiency compared with existing technologies. Summary of the Invention

[0006] This invention addresses the technical problems existing in the prior art by providing an auxiliary device and construction method for laying drainage boards using a tearable membrane vacuum pre-compression method.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0013] Furthermore, the insert plate unit includes a steel pipe sleeve, a drive motor, a transmission chain, a drive wheel, and a protective box. The steel pipe sleeve passes through the protective box, and the drainage plate passes through the steel pipe sleeve. The drive motor is installed on the upper outer wall of the protective box, and the drive wheel is installed on the inner side wall of the protective box. The rotation shaft of the drive wheel is transmitted to the output end of the drive motor through the transmission chain. The drive wheel meshes with the side wall of the steel pipe sleeve located inside the protective box.

[0014] Multiple drive motors and drive wheels are provided, and each drive motor and drive wheel is arranged in a one-to-one correspondence. The drive motors and drive wheels are distributed on both sides of the steel pipe sleeve.

[0015] Furthermore, the horizontal film-tearing unit includes a pneumatic lifting rod, a horizontal film-tearing guide rail, and a horizontal film-tearing assembly. The pneumatic lifting rod includes a fixed part and an extended part. The fixed part is fixed to the lower wall of the protective box, and the extended part is fixedly connected to the upper wall of the horizontal film-tearing guide rail. The horizontal film-tearing guide rail has a frame structure, and the steel pipe sleeve passes through the horizontal film-tearing guide rail.

All the sliding wheels are located on one side of the film-tearing platform and are slidably connected to the horizontal film-tearing guide rail. The film-tearing cutter is installed on the side wall of the film-tearing platform opposite to the sliding wheels. The film-tearing cutter is correspondingly arranged with a sliding wheel that is not connected to a servo motor.

[0017] Furthermore, the horizontal film-tearing guide rail is provided with an inner slide rail and an outer slide rail. A sliding wheel connected to a servo motor and a sliding wheel not connected to a servo motor are installed on the inner slide rail, and the remaining two sliding wheels are installed on the outer slide rail.

[0018] Furthermore, the vertical film-tearing unit includes a vertical film-tearing guide rail, a telescopic bracket, and a vertical film-tearing assembly. The vertical film-tearing guide rail is mounted on the telescopic support rod via the telescopic bracket. The vertical film-tearing guide rail is slidably connected to the support plate, and the vertical film-tearing assembly is slidably connected to the vertical film-tearing guide rail. The structure of the vertical film-tearing assembly is the same as that of the horizontal film-tearing assembly.

The outer film clamp is installed on the side wall of the telescopic support plate near the driving element. The outer film clamp is used to clamp the outer film at the lower end of the drainage board. The driving element adjusts the distance between the two telescopic support plates by driving the telescopic rod, thereby opening the outer film at the lower end of the drainage board.

[0021] Furthermore, multiple telescopic support rods are provided for stepless adjustment. A verticality sensing unit is provided on the side wall of the telescopic support rod. The verticality sensing unit includes an infrared transmitter and an infrared receiver.

[0024] S2. The film-tearing fixing unit clamps and opens the outer film at the lower end of the drainage board;

[0025] S3. The vertical tearing guide rail moves to the tearing position under the drive of the telescopic bracket.

Then the vertical tearing unit returns to the initial position.

[0026] S4. The horizontal film-tearing guide rail moves to the top of the crack under the action of the pneumatic lifting rod. The horizontal film-tearing assembly cuts around the horizontal film-tearing guide rail to cut off the outer film of the drainage board. After the film cutting is completed, the horizontal film-tearing unit returns to the initial position.

[0027] S5. Start the drive motor to move the steel pipe sleeve downwards, thereby inserting the drainage board into the soil. After reaching the specified insertion depth, pull it back to the ground and cut off the excess drainage board to complete the film tearing and insertion process.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] This invention utilizes the coordinated operation of an insert plate unit, a horizontal film-tearing unit, a vertical film-tearing unit, and a film-tearing fixing unit. The insert plate unit secures the drainage board, then clamps and expands the lower end of the drainage board's outer membrane. Next, the vertical film-tearing unit cuts a vertically extending slit in the outer membrane, and the horizontal film-tearing unit cuts around the top of the slit horizontally.

The drive wheel 104 fits against the side wall of the steel pipe sleeve 101 located inside the protective box 105. The drive motor 102 rotates, which drives the drive wheel 104 to rotate through the transmission chain 103, thereby driving the steel pipe sleeve 101 to move up and down. The drainage plate 8 is installed through the steel pipe sleeve 101. There is friction between the drainage plate 8 and the steel pipe sleeve 101. The depth of the drainage plate 8 inserted into the ground is controlled by the up and down movement of the steel pipe sleeve 101.

The upper end of the horizontal film-tearing guide rail 202 is connected, and the inner and outer side walls of the horizontal film-tearing guide rail 202 are provided with slide rails, which are designated as inner slide rails and outer slide rails. The horizontal film-tearing assembly 203 is set to clamp the horizontal film-tearing guide rail 202, that is, the horizontal film-tearing assembly 203 is slidably connected to the inner slide rail and the outer slide rail of the horizontal film-tearing guide rail 202. The horizontal film-tearing assembly 203 can slide along the inner slide rail and the outer slide rail to perform horizontal annular cutting; the drainage plate 8 is set through the horizontal film-tearing guide rail 202.

The four sliding wheels 204 are located on the same side wall of the film-tearing platform 205. One sliding wheel 204 connected to a servo motor 209 and the other sliding wheel 204 not connected to a servo motor 209 are installed in the inner slide rail of the horizontal film-tearing guide rail 202. The remaining two sliding wheels 204 are installed... Within the outer slide rail of the horizontal film-tearing guide rail 202, one of the sliding wheels 204 installed in the inner and outer slide rails is driven to rotate by a servo motor 209. Driven by the servo motor 209, the horizontal film-tearing assembly 203 can slide along the inner and outer slide rails. The sliding wheel 204 not connected to the servo motor 209 is installed on the film-tearing platform 205 by connecting bolts 206. The film-tearing cutter 207 is connected to the film-tearing platform 205 by fixing screws 208. The film-tearing cutter 207 is located on the opposite side of the film-tearing platform 205 where the sliding wheel 204 is installed.

The vertical film-tearing guide rail 301 is slidably connected to the upper wall of the support plate 4 and is perpendicular to the support plate 4. The vertical film-tearing guide rail 301 is positioned between the drainage plate 8 and one of the telescopic support rods 7. The telescopic bracket 302 is positioned between the vertical film-tearing guide rail 301 and the telescopic support rod 7. The telescopic bracket 302 is used to adjust the distance between the vertical film-tearing guide rail 301 and the drainage plate 8. The vertical film-tearing assembly 303 is slidably connected to the vertical film-tearing guide rail 301. The structure of the film-tearing assembly 303 is the same as that of the horizontal film-tearing assembly 203. The vertical film-tearing guide rail 301 has a set of slide rails on a set of opposite side walls. A set of sliding wheels 204 in the vertical film-tearing assembly 303 are installed in the slide rail on one side of the vertical film-tearing guide rail 301, and another set of sliding wheels 204 are installed in the slide rail on the other side of the vertical film-tearing guide rail 301. The sharp end of the film-tearing cutter 207 in the vertical film-tearing assembly 303 is set towards the outer wall of the drainage plate 8. The servo motor 209 in the vertical film-tearing assembly 303 controls the vertical film-tearing assembly 303 to move along the vertical direction of the vertical film-tearing guide rail 301.

[0044] like Figure 2 , Figure 5 As shown, the film-tearing fixing unit 5 includes a driving element 501, an outer film clamp 502, and a telescopic support plate 503. The driving element 501 is disposed on the upper wall of the support plate 4. Multiple telescopic rods are connected to the driving element 501. Two telescopic support plates 503 are inserted through the telescopic rods. The distance between the telescopic support plates 503 is adjusted by the telescopic rods. The telescopic support plate 503 near the driving element 501 is connected to the outer mold clamp on its side wall. The outer film clamp 502 and the telescopic support plate 503 near the driving element 501 are used to clamp the outer film of the drainage plate 8. By adjusting the extension length of the telescopic rods through the driving element 501, the distance between the two telescopic support plates 503 is adjusted, making the distance larger, thereby tearing the outer film at the lower end of the drainage plate 8.

[0045] like Figure 2 As shown, the length of the telescopic support rod 7 can be infinitely adjusted. By adjusting the length of the telescopic support rod 7, the distance between the insertion plate unit 1 and the support plate 4 is adjusted. A verticality sensing unit 6 is also provided on the side wall of the telescopic support rod 7. The verticality sensing unit 6 includes an infrared transmitter 601 and an infrared receiver 602. The infrared transmitter 601 and the infrared receiver 602 are respectively set on the opposite side walls of the two telescopic support rods 7. The infrared transmitter 601 and the infrared receiver 602 are set at the same height. Signal transmission and reception are performed through the infrared transmitter 601 and the infrared receiver 602 to monitor whether the verticality of the steel pipe sleeve 101 meets the engineering requirements during the insertion process.

[0046] This invention also provides a construction method for an auxiliary device for laying drainage boards using a tearable membrane vacuum preloading method, comprising the following steps:

[0047] S1. Place the tearable film vacuum pre-compression drainage board laying auxiliary device at the insertion position of the drainage board 8, pass the drainage board 8 through the upper end of the steel pipe sleeve 101, and adjust the height of the telescopic support rod 7 according to the project requirements to achieve a suitable tearing height.

[0048] S2. The film-tearing fixing unit 5 clamps and opens the outer film at the lower end of the drainage plate 8 to facilitate the film-tearing process.

[0049] S3. The vertical tearing guide rail 301 moves to the appropriate tearing position under the drive of the telescopic bracket 302. The vertical tearing assembly 303 moves from bottom to top along the vertical tearing guide rail 301 to cut a crack in the outer membrane of the drainage plate 8. Then the vertical tearing unit 3 returns to the initial position.

[0050] S4. The horizontal film-tearing guide rail 202 moves to the designed film-tearing height, i.e. the uppermost end of the crack, under the action of the pneumatic lifting rod 201. The horizontal film-tearing assembly 203 cuts around the horizontal film-tearing guide rail 202 to cut off the outer film of the drainage board 8. After the film cutting is completed, the horizontal film-tearing unit 2 returns to the initial position.

[0051] S5. Start the drive motor 102 to move the steel pipe sleeve 101 downward, thereby driving the drainage board 8 to be inserted into the soil. After reaching the specified insertion depth, pull it back to bring the steel pipe sleeve 101 back above the ground. Cut off the excess part of the drainage board 8 to complete the film tearing and insertion process. The specified insertion depth is the same as the length of the crack.

[0052] This invention utilizes the coordinated operation of an insert plate unit 1, a horizontal film-tearing unit 2, a vertical film-tearing unit 3, and a film-tearing fixing unit 5. The insert plate unit 1 fixes the drainage board 8, then clamps and expands the lower end of the outer film of the drainage board 8. Next, the vertical film-tearing unit 3 cuts a vertically extending slit in the outer film of the drainage board 8, and the horizontal film-tearing unit 2 cuts around the top of the slit horizontally to cut the outer film. Then, the insert plate unit 1 inserts the drainage board 8 into the soil to a specified depth, cutting the drainage board 8 above the soil surface, thus completing the installation of the drainage board 8. This invention achieves a precise film-tearing process for the outer film of the drainage board 8, solving the problems of inaccuracy and low efficiency associated with manual film tearing, saving time and labor, and reducing construction costs.

[0053] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention.

The outer film clamp is used to clamp the outer film at the lower end of the drainage board. The driving element adjusts the distance between the two telescopic support plates by driving the telescopic rod, thereby opening the outer film at the lower end of the drainage board.

5. The vacuum preloading method of a tearable membrane drainage board laying auxiliary device according to claim 1, characterized in that, The telescopic support rods are provided in multiple ways and are infinitely adjustable. A verticality sensing unit is provided on the side wall of the telescopic support rod. The verticality sensing unit includes an infrared transmitter and an infrared receiver. The infrared transmitter and the infrared receiver are set on different side walls of the telescopic support rods and are correspondingly set at the same height.

6. A construction method of a vacuum preloading method drainage board laying aid device for a tearable film, characterized by, Includes the following steps: S1. Place the tearable film vacuum pre-compression drainage board laying auxiliary device as described in claim 2 or 3 at the insertion plate position of the drainage board, pass the drainage board through the upper end of the steel pipe sleeve, and adjust the height of the telescopic support rod to achieve the tearing height. S2. The film-tearing fixing unit clamps and opens the outer film at the lower end of the drainage board; S3. The vertical film-tearing guide rail moves to the film-tearing position under the drive of the telescopic bracket. The vertical film-tearing assembly moves from bottom to top along the vertical film-tearing guide rail to cut a crack in the outer film of the drainage board. Then the vertical film-tearing unit returns to the initial position. S4. The horizontal film-tearing guide rail moves to the top of the crack under the action of the pneumatic lifting rod. The horizontal film-tearing assembly cuts around the horizontal film-tearing guide rail to cut off the outer film of the drainage board. After the film cutting is completed, the horizontal film-tearing unit returns to the initial position. S5. Start the drive motor to move the steel pipe sleeve downwards, thereby inserting the drainage board into the soft soil foundation. After reaching the specified insertion depth, pull it back to the ground level and cut off the excess drainage board to complete the membrane tearing and insertion process.
