Description

Technical Field

[0001] This invention relates to the field of geological strata treatment technology, specifically a newly developed automated slab insertion system and method for hydraulically filled soil foundations. Background Technology

[0002] In land reclamation and artificial island dredging and filling projects, "muddy soup"-like ultra-soft soil sites are often formed. This newly filled silt is ultra-soft and weak silt with extremely high water content. It is mostly in a soft plastic to flowable state, and even presents as "floating mud or flowing mud". It has basically no strength and bearing capacity. Various construction machinery cannot carry out construction operations on the surface. It cannot meet the requirements of conventional vacuum preloading method for laying sand cushion layer and inserting drainage board. Therefore, before conventional soft foundation treatment, the shallow ultra-soft soil must be reinforced first. Only after it forms a hard shell layer with certain strength and bearing capacity can subsequent soft foundation treatment be carried out.

[0003] For reinforcing shallow layers of newly filled soil that are extremely soft, existing techniques often involve manually inserting slabs into the shallow layer of the filled foundation using equipment, followed by vacuuming to achieve shallow reinforcement. However, this manual slab insertion method is inefficient and carries significant construction risks due to the risk of equipment tipping over, jeopardizing the safety of construction workers.

[0004] In summary, there is a need for a board insertion system that can directly install board insertion equipment onto newly filled soil to reduce or eliminate the need for manual entry into extremely soft sites for board insertion operations. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a novel automated slab insertion system and method for dredged and reclaimed soil foundations, which can solve the problems described in the background art.

[0006] The technical solution to achieve the objective of this invention is as follows: an automated slab insertion system for recently reclaimed soil foundations, comprising an air-floating platform and an insertion mechanism. The insertion mechanism is slidably mounted on the air-floating platform, enabling it to move along a path formed by the air-floating platform to different locations within the recently reclaimed soil. The air-floating platform is used to fix the system to the surface of the recently reclaimed soil via negative pressure adsorption. The insertion mechanism is used to insert drainage slabs into the soil layers of the recently reclaimed soil. The air-floating platform includes at least one air chamber and at least two air cells, each air cell being independently separated and arranged along the horizontal direction of the air-floating platform. The air cells are used to change the vertical deformation of the air cells by adjusting the air pressure inside the air cells, thereby changing the height of the air cells and adjusting the horizontal state of the air-floating platform. The air chambers are located below the air-floating platform. When the air-floating platform is placed on the surface of the recently filled soil, the surface of the recently filled soil is sealed to the air chambers.

[0007] Furthermore, the floating bridge includes a guide rail, a rigid plate, an air cushion, and a float that are stacked and connected together from top to bottom. The guide rail is used to slide with the insert plate mechanism and is located on the rigid plate. The air cushion includes an inflation port and multiple air chambers, which are distributed at intervals along the transverse direction of the air cushion. The lower part of the float is provided with the air chamber.

[0008] Furthermore, the air cushion is equipped with an interconnected main pipeline and several branch pipelines. The main pipeline extends along the axial direction of the air cushion and is connected to the inflation port. The branch pipelines are distributed at intervals along the axial direction, with each branch pipeline extending laterally. Branch pipelines extend to each air chamber, and each branch pipeline is equipped with an opening and closing device. Each opening and closing device corresponds to one air chamber, and the opening and closing device is connected to the corresponding air chamber.

[0009] Furthermore, an air extraction pipe is also provided inside the air chamber, and the air extraction pipe is installed on the float. It also includes a balancer, which is used to detect the levelness of the pontoon bridge.

[0010] Furthermore, the air-floating platform includes at least two long floating bridge chains, each of which includes multiple floating bridges that are connected end to end in sequence, and the insert plate mechanism spans across the two floating bridge chains.

[0011] Furthermore, the insertion mechanism includes a traveling mechanism, a working bridge, and an insertion device. The insertion device is slidably mounted on the working bridge and can slide along the working bridge. The traveling mechanism is slidably connected to the guide rail. There is a traveling mechanism at each end of the working bridge. The inserting plate device is located between the two traveling mechanisms. The inserting plate device is used to insert the drainage plate into the target position of the newly filled soil.

[0012] Furthermore, the insertion plate device includes a sleeve, a component moving mechanism, a power system, and a storage frame. The storage frame is used to place the drainage plate. The power system is sleeved and installed on the sleeve. The power system is used to insert the drainage plate into the target position of the shallow surface layer of the recently filled soil. The sleeve passes vertically through the working bridge. The component moving mechanism is slidably sleeved on the working bridge. The storage frame is installed on the component moving mechanism.

[0013] Furthermore, the insertion plate mechanism also includes a communication module, which is mounted on the component moving mechanism. The insert mechanism also includes an RTK sensor, which is mounted on the top of the sleeve. The RTK sensor is used to determine the current height and verticality of the sleeve. The automatic insertion system also includes a high-pressure gas cylinder, a switch, and a connecting latch. The high-pressure gas cylinder is connected to the air chamber on the air cushion through a connecting pipe. A switch is installed on the connecting pipe to control whether the connecting pipe is in a closed state. The connecting latch is used to enable the connecting pipe to be plugged into and quickly connected to the air chamber.

[0014] An automated slab insertion method for recently reclaimed soil foundations, applied to an automated slab insertion system for recently reclaimed soil foundations, includes the following steps: Step 1: Assemble the individual floating bridges to form a floating bridge grid. Use an air pump to extract gas from the air chamber to create a vacuum, thereby fixing the position of the floating bridges. Step 2: By inflating the air chambers, each air chamber undergoes longitudinal deformation, causing the elevation of the rigid plate above the air chambers to rise until it reaches the preset elevation. The level of the floating bridge is then detected by the balancer. If the bridge is level, proceed to step 3; otherwise, proceed to step 21. Step 21: Adjust the inflation volume of each air chamber corresponding to the inclined side by using the opening and closing device to adjust the elevation of the rigid plate at the location of the inclined side until the floating bridge reaches a horizontal state again, and then jump to step 3. Step 3: Install the traveling mechanism on the guide rail of the floating bridge, connect the traveling mechanism to the working bridge, and install the insert plate device on the working bridge; Step 4: Check again whether the floating bridge and the working bridge are in a horizontal state. If they are not in a horizontal state, skip to step 21 until they are in a horizontal state. Step 5: The inserter device inserts the drainage board into the target position of the newly filled soil.

[0015] Furthermore, when the inserting device moves along the working bridge to the designated position, the power system on the inserting device inserts the sleeve and drainage board into the target position of the newly filled soil. When the descent height of the sleeve matches the insertion depth of the drainage board, the insertion stops, and then the sleeve is pulled out, leaving the drainage board at the target position of the newly filled soil, thus completing the insertion operation of a single drainage board. This process is repeated to complete the insertion operation of multiple drainage boards.

[0016] The beneficial effects of this invention are as follows: This invention achieves rapid construction of newly reclaimed land through the synergistic effect of the floating bridge and the insert plate device, improving construction efficiency compared to traditional methods. Furthermore, this invention combines the three major advantages of rapid construction, precise construction, and economy, effectively avoiding the safety risks present in existing technologies. It is suitable for demanding engineering scenarios such as newly reclaimed land and has broad application prospects. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-6 As shown, an automated insert plate system for newly filled soil foundations includes an air-floating platform and an insert plate mechanism. The insert plate mechanism is slidably mounted on the air-floating platform, allowing it to move along the path formed by the air-floating platform to different positions in the shallow surface layer of the newly filled soil. The air-floating platform is used to fix the surface of the shallow surface layer of the newly filled soil by negative pressure adsorption, so that the insert plate mechanism can be in a stable state to insert the drainage plate 16 for drainage consolidation into the soil layer of the shallow surface layer of the newly filled soil.

[0019] The air-floating platform includes at least one air chamber 11 and at least two air cells 7. Each air cell 7 is independently separated, allowing for individual control without interconnection. The air cells 7 are positioned horizontally along the platform. Adjusting the air pressure within each air cell 7 changes its vertical deformation, thus altering its height. This allows the air-floating platform to be kept horizontal, ensuring a more stable adhesion to the surface of the recently filled soil. The air chamber 11 is located below the air-floating platform. When the platform is placed on the surface of the recently filled soil, the surface is sealed within the air chamber 11. By extracting air from the air chamber 11, a negative pressure is created, allowing the air-floating platform to be fixed to the surface of the recently filled soil through negative pressure adhesion.

[0020] It is understandable that the air chamber 7 can be made of flexible material, and the strength of the flexible material used in the transverse and longitudinal directions of the air chamber 7 is different, so that when the air pressure inside the air chamber 7 increases, the air chamber 7 mainly undergoes longitudinal deformation to adjust the height, while the transverse deformation of the air chamber 7 is extremely small and can be ignored.

[0021] For example, the air-floating platform includes a plurality of floating bridges 20, which are connected together to form and define a movable path for the inserter.

[0022] refer to Figure 4 The individual floating bridges 20 are connected to form a closed rectangular grid of square floating bridges 20, and the inserting machine can move along a vertical path in the grid of square floating bridges 20.

[0023] For example, two adjacent floating bridges 20 are connected by a locking member 26, which includes a snap-fit ​​25 and a retaining ring 24. The snap-fit ​​25 is engaged with the retaining ring 24. One snap-fit ​​25 on one of the two adjacent floating bridges 20 is engaged with the retaining ring 24 on the other, thereby connecting the two floating bridges 20 together.

[0024] The floating bridge 20 includes a guide rail 5, a rigid plate 6, an air cushion 4, and a float 8, which are stacked and connected together from top to bottom. The guide rail 5 is used for sliding connection with the insertion plate mechanism, allowing the insertion plate mechanism to slide on the guide rail 5, thereby enabling the insertion plate mechanism to slide on the air-bearing platform. The guide rail 5 can be located in the center of the rigid plate 6, and the guide rail 5 can be fixedly connected to the rigid plate 6 by driving steel nails into the rigid plate 6. The rigid plate 6 is a high-strength, non-deformable plate structure, for example, it can be made of steel plate, alloy plate, etc. The air cushion 4 includes an inflation port and multiple air chambers 7. The inflation port can be connected to an air source to inject gas into each air chamber 7. The air chambers 7 are distributed at intervals along the transverse direction of the air cushion 4, and each air chamber 7 is independent and does not affect each other.

[0025] For example, the air cushion 4 is further provided with a main pipe 12 and several branch pipes 14 that are interconnected. The main pipe 12 extends along the axial direction of the air cushion 4 and is connected to the inflation port. The branch pipes 14 are distributed at intervals along the axial direction, and each branch pipe 14 extends laterally. The branch pipes 14 extend to each air chamber 7, and each branch pipe 14 is provided with an opening and closing device 13. Each opening and closing device 13 corresponds to one air chamber 7 and is connected to the corresponding air chamber 7. The air source can inflate each air chamber 7 through the inflation port, the main pipe 12, the branch pipes 14 and the opening and closing device 13, and the inflation amount of each air chamber 7 can be controlled by the opening and closing device 13.

[0026] The opening and closing device 13 can be controlled by wireless communication, that is, by sending corresponding commands wirelessly to open and close the opening and closing device 13. When it is open, air can be supplied to the air chamber 7 through the opening and closing device 13. When it is closed, air cannot be supplied to the air chamber 7 through the opening and closing device 13.

[0027] The purpose of providing independent air chambers 7 and a corresponding opening and closing device 13 for each air chamber 7 is to allow for adjustment of the tilted air cushion 4 (correspondingly, the floating bridge 20 is also tilted). (See reference) Figure 3 Assuming the pontoon bridge 20 is in a non-horizontal state tilted to the right, that is, tilted downwards from left to right, the two opening and closing devices 13 labeled c and d in the figure can be opened to fill the corresponding two air chambers 7, thereby raising the elevation of the air chambers 7 (that is, the two air chambers 7 bulge and expand), so that the pontoon bridge 20 returns to a near-horizontal state. Then, the opening and closing device 13 labeled c is closed, and the air chamber 7 corresponding to the opening and closing device 13 labeled d is continued to be filled with air for fine adjustment, and finally a horizontal state is achieved, that is, a balanced state is reached.

[0028] Figure 3 The labels a, b, c, and d in the figure indicate the four opening and closing devices 13. Each rectangular square defined by the dashed line in the figure is an air chamber 7.

[0029] The lower part of the float 8 is provided with the air cavity 11, which can be U-shaped. The density of the float 8 is less than a specific density threshold (e.g., 1×10⁻⁶). 3 kg / m 3 The attached diagram can be made of materials such as foam and wood.

[0030] For example, an air extraction pipe 10 is also provided inside the air cavity 11. The air extraction pipe 10 is installed on the float 8. For example, the air extraction pipe 10 is fixedly installed on the top inner wall of the air cavity 11 of the float 8.

[0031] For example, it also includes a balancer 9, which is used to detect the horizontal state of the pontoon 20, that is, to detect whether the pontoon 20 is in a horizontal state, and whether it is tilted to the right or to the left. The balancer 9 is mounted on the top surface of the rigid plate 6 and is located on one side of the guide rail 5.

[0032] For example, the air-floating platform includes at least two long floating bridge chains 20, each of which includes multiple floating bridges 20 connected end to end. The insert plate mechanism spans the two floating bridge chains 20 to achieve smoother movement of the insert plate mechanism and a larger working area that can cover the shallow surface layer of the newly filled soil, thereby achieving a larger coverage area for the insert plate operation.

[0033] refer to Figure 4 The schematic square floating bridge 20 grid has two floating bridge chains on the left and right sides, and the two ends of the insert plate mechanism are slidably connected to the guide rails 5 on the floating bridge chains.

[0034] For example, the inserting plate mechanism includes a traveling mechanism 19, a working bridge 17, and an inserting plate device. The inserting plate device is slidably mounted on the working bridge 17 and can slide along the working bridge 17 so that the inserting plate device can move to different positions on the working bridge 17, thereby enabling inserting plate operations to be performed on different positions of the newly filled soil.

[0035] The traveling mechanism 19 is slidably connected to the guide rail 5, and one traveling mechanism 19 is provided at each end of the working bridge 17. The inserting plate device is located between the two traveling mechanisms 19 and is used to insert the drainage plate 16 to the target position of the newly filled soil.

[0036] For example, the insertion device includes a sleeve 21, a component moving mechanism 22, a power system 23, and a storage frame. The storage frame is used to hold the drainage board 16. The power system 23 is sleeved and mounted on the sleeve 21 and is used to insert the drainage board 16 into the target location on the shallow surface of the recently filled soil. The sleeve 21 passes vertically through the working bridge 17, the component moving mechanism 22 is slidably sleeved on the working bridge 17, and the storage frame is mounted on the component moving mechanism 22.

[0037] It is understandable that the power system 23 that enables the drainage board 16 to be inserted into the target position of the shallow surface of the newly filled soil is existing technology, so the specific composition and structure of the power system 23 will not be described in detail.

[0038] For example, the insert mechanism further includes a communication module 18, which is mounted on the component moving mechanism 22.

[0039] For example, the insert mechanism also includes an RTK sensor 15, which is mounted on the top of the sleeve 21. The RTK sensor 15 is used to locate the current height and verticality of the sleeve 21.

[0040] For example, the automatic insertion system also includes a high-pressure gas cylinder 1, a switch 2, and a connecting latch 3. The high-pressure gas cylinder 1 is connected to the air chamber 7 on the air cushion 4 via a connecting pipe. The switch 2 is installed on the connecting pipe to control whether the connecting pipe is in a closed state, thereby controlling whether the high-pressure gas cylinder 1 is allowed to fill the air chamber 7. The connecting latch 3 is used to enable the connecting pipe to be plugged into and quickly connected to the air chamber 7.

[0041] The present invention also provides an automated slab insertion method for recently reclaimed soil foundations, applied to the automated slab insertion system for recently reclaimed soil foundations, the method comprising the following steps: Step 1: Assemble the individual floating bridges 20 to form a grid of floating bridges 20. Use an air pump to extract gas from the air chamber 11 to create a vacuum, thereby fixing the position of the floating bridges 20.

[0042] Step 2: By inflating the air chambers 7, each air chamber 7 undergoes longitudinal deformation, causing the elevation of the rigid plate 6 above the air chambers 7 to rise until it reaches the preset elevation. The level of the floating bridge 20 is then detected by the balancer 9. If it is level, proceed to step 3; otherwise, proceed to step 21.

[0043] Step 21: Adjust the inflation volume of each air chamber 7 corresponding to the inclined side by using the opening and closing device 13 to adjust the elevation of the rigid plate 6 at the location of the inclined side until the floating bridge 20 reaches a horizontal state again, and then jump to step 3.

[0044] Step 3: Install the traveling mechanism 19 on the guide rail 5 of the floating bridge 20. The traveling mechanism 19 is connected to the working bridge 17, and the insert plate device is installed on the working bridge 17.

[0045] Step 4: Check again whether the floating bridge 20 and the working bridge 17 are in a horizontal state. If they are not in a horizontal state, proceed to step 21 until they are in a horizontal state.

[0046] Understandably, the main reason for checking the horizontal position again in this step is to avoid changes in the horizontal position that may be caused by the center shift due to the addition of the insert plate mechanism.

[0047] Step 5: The inserter inserts the drainage board 16 into the target position of the newly filled soil.

[0048] For example, when the inserting device moves along the working bridge 17 to the designated position, the power system 23 on the inserting device inserts the sleeve 21 and the drainage board 16 into the target position of the newly filled soil. The RTK sensor 15 on the sleeve 21 records the elevation change and verticality of the sleeve 21. When the descent height of the sleeve 21 is consistent with the insertion depth of the drainage board 16, the power system 23 stops outputting power to stop the insertion, and then the sleeve 21 is pulled out. The drainage board 16 remains in the target position of the newly filled soil, thus completing the insertion operation of a single drainage board 16. By proceeding in sequence, the insertion operation of multiple drainage boards 16 can be completed.

[0049] Practical application has shown that this invention can achieve a grounding pressure of less than 5 kPa in newly filled ultra-soft soil foundations with a water content of >80%, thereby enabling automated board insertion operations on ultra-soft soil sites, reducing or eliminating manual labor and improving efficiency.

Any other functionally equivalent embodiments fall within the scope of protection of the invention. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the scope of protection of the claims of this invention.
