[0001] The invention belongs to the technical field of mooring foundations, and in particular relates to an installation method of a double-layer flat plate bearing anchor and an embedding track marking method. Background Art

[0002] Drag embedded double-layer flat plate bearing anchor ( Figure 2 The invention discloses a double-layer flat plate anchor having a high bearing capacity. However, the angle between the anchor plates is difficult to control during the installation and embedding process of the anchor into the soil. For example, the anchor plates are opened too early, the angle increases, and the resistance increases, which reduces the ultimate embedding depth of the drag-embedded double-layer flat plate bearing anchor, thereby affecting the bearing capacity of the anchor.

[0003] In the anchor embedding trajectory test research, in order to observe the movement trajectory of the drag anchor in the soil, a large number of external equipment such as X-scanning equipment, GPS positioning equipment, sensor remote sensing equipment, etc. are often used. These methods all require computer post-processing to synthesize the embedding trajectory image. The peripheral observation error is unavoidable and the post-processing is extremely complicated, making it impossible to intuitively observe the embedding trajectory of the anchor plate.

[0004] Therefore, the present invention proposes a method for installing a double-layer flat plate bearing anchor and a method for embedding a track marker to solve the above technical problems. Summary of the Invention

[0008] Step 2: Dragging into the soil: dragging the double-layer flat plate bearing anchor along the direction of the head end of the double-layer flat plate bearing anchor to dig the double-layer flat plate bearing anchor into the soil layer;

[0009] Step 3: Drag and fix; pull the double-layer flat plate bearing anchor in the opposite direction to unfold the double-layer flat plate bearing anchor and fix it in the soil layer.

[0010] Preferably, in step 2, the double-layer flat plate bearing anchor is tilted into the soil layer when dragged along the head end, and the angle between the head end of the double-layer flat plate bearing anchor and the horizontal plane gradually decreases until the head end of the double-layer flat plate bearing anchor is in the same direction as the horizontal plane, and then the dragging stops.

[0011] Preferably, in step three, when the double-layer flat plate bearing anchor is dragged in the reverse direction, the upper anchor plate and the lower anchor plate are respectively subjected to force, and the tail ends are deflected in directions away from each other, and the hydraulic support rod is stretched and lengthened.

[0012] A method for installing and embedding a double-layer flat plate bearing anchor into a track marking comprises the following steps:

[0013] Step 1: Install the marking device; install the marking device into the double-layer plate bearing anchor so that the bottom end of the marking device extends out of the lower end surface of the double-layer plate bearing anchor;

[0014] Step 2: Filling marking ink: Filling marking ink into the marking device;

[0015] Step 3: Prepare the test equipment; prepare the test equipment that is convenient for observation and install the double-layer flat plate bearing anchor on the test equipment;

[0016] Step 4: Drag test; drag along the head end direction of the double-layer flat plate bearing anchor to allow the double-layer flat plate bearing anchor to be excavated into the test equipment;

[0017] Step 5: Observe and record the embedding track; observe and record the track left by the marking device in the test equipment.

[0018] Preferably, the marking device includes an ink storage tank fixedly mounted on the top of the lower anchor plate, the bottom end of the ink storage tank is fixedly connected to an ink tank bottom plate, and the ink tank bottom plate is embedded and fixed in the lower anchor plate; the bottom end of the ink tank bottom plate is fixedly connected to an ink outlet assembly, and the ink outlet assembly extends out of the bottom end of the lower anchor plate.

[0019] Preferably, the ink outlet assembly includes an ink outlet fixedly connected to the bottom end of the ink tank bottom plate, and the ink outlet extends out of the lower anchor plate; the outlet of the ink outlet is detachably connected to a rotating ball, the bottom end of the rotating ball extends out of the ink outlet, the top end of the rotating ball abuts against a top ball spring, and the top end of the top ball spring is fixedly connected to the top end of the inner cavity of the ink storage tank.

[0020] Preferably, the test equipment includes a transparent test container filled with a transparent filler; a guide rail is fixed to the top of the test container, and the anchor cable fixed to the double-layer flat plate bearing anchor passes through the guide rail and is connected to a winch for transmission.

Compared with the original installation method of directly opening and dragging forward, this installation method significantly reduces the influence of soil resistance, making the anchor plate easier to embed and eventually able to embed to a deeper depth, greatly improving the bearing capacity of the anchor, which will be more conducive to resisting the influence of external forces in nature and ensuring the safety of offshore operating platforms and personnel. In addition, the use of the method of the present invention will reduce the number of towing anchor foundations required for installation in marine engineering, thereby saving installation consumption and shortening the installation period of the offshore floating platform foundation, and contributing to the operation of deep-sea floating oil and gas production platforms at deeper ocean depths and more complex marine environments. The installation embedding trajectory marking method of the double-layer flat plate bearing anchor disclosed in the present invention does not require the aid of an external scanning device, greatly reduces the cost of the experiment, eliminates errors during observation, and intuitively displays the embedding trajectory without affecting the stress characteristics and movement of the dragged embedded double-layer flat plate bearing anchor during embedding. This method is conducive to more accurate research on the installation process of the double-layer flat plate bearing anchor.

[0023] The method of the present invention reduces the influence of the angle on the ultimate embedding depth of the drag-embedded double-layer flat plate bearing anchor without changing the structure of the double-layer flat plate bearing anchor, greatly increases the immersion depth, and increases the bearing capacity of the double-layer flat plate bearing anchor.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figure 1-7 As shown, this embodiment provides a method for installing a double-layer flat plate bearing anchor, comprising the following steps:

[0036] Step 1: Anchoring into the water; closing the upper anchor plate 11 and the lower anchor plate 12 of the double-layer flat plate bearing anchor 1, and throwing the double-layer flat plate bearing anchor 1 into the water so that it contacts the soil surface;

[0037] Step 2: Drag into the soil: Drag the double-layer flat plate bearing anchor 1 along the direction of the head end of the double-layer flat plate bearing anchor 1 so that the double-layer flat plate bearing anchor 1 is excavated into the soil layer;

[0038] Step 3: Drag and fix; pull the double-layer flat plate bearing anchor 1 in the reverse direction to unfold the double-layer flat plate bearing anchor 1 and fix it in the soil layer.

[0039] The installation method of the double-layer flat plate bearing anchor 1 disclosed in the present invention adopts the method of first dragging the double-layer flat plate bearing anchor 1 in the direction of the head end when the double-layer flat plate bearing anchor 1 is embedded in the ground, and then dragging it in the opposite direction after the double-layer flat plate bearing anchor 1 penetrates deep enough into the ground, so that the double-layer flat plate bearing anchor 1 is opened and stuck in the ground. Compared with the original installation method of directly opening and dragging forward, this installation method significantly reduces the influence of soil resistance, making the anchor plate easier to embed and eventually able to embed to a deeper depth, greatly improving the bearing capacity of the anchor, which will be more conducive to resisting the influence of external forces in nature and ensuring the safety of offshore operating platforms and personnel. In addition, the use of the method of the present invention will reduce the number of towing anchor foundations required for installation in marine engineering, thereby saving installation consumption and shortening the installation period of the offshore floating platform foundation, and contributing to the operation of deep-sea floating oil and gas production platforms at deeper ocean depths and more complex marine environments.

[0040] Furthermore, the double-layer flat plate bearing anchor 1 includes an upper anchor plate 11 and a lower anchor plate 12. The lower anchor plate 12 is hinged at the bottom end of the upper anchor plate 11. A number of hydraulic support rods 13 are fixed between the tail ends of the upper anchor plate 11 and the lower anchor plate 12. A number of fixing rings 14 are fixed to the top end of the upper anchor plate 11, and an anchor cable 15 is fixed to the fixing ring 14. The upper anchor plate 11 and the lower anchor plate 12 are hinged at one end and open at the other end and can rotate along the hinged end. The existing installation method of the double-layer flat plate bearing anchor 1 is to directly drag it in the direction of the opening of the upper anchor plate 11 and the lower anchor plate 12. During the towing process, due to the resistance of the soil, the hydraulic support rod 13 is stretched, and the angle between the upper anchor plate 11 and the lower anchor plate 12 gradually increases until the angle is fully opened. However, the disadvantage of this method is that as the angle becomes larger, the diving ability of the double-layer flat plate bearing anchor 1 decreases, which ultimately leads to a smaller depth and insufficient bearing capacity. In order to ensure the stability of the floating equipment on the sea surface, it is necessary to increase the number of double-layer flat plate bearing anchors 1, which reduces the fixing efficiency and increases the cost.

[0041] Furthermore, a first excavation angle 16 and a second excavation angle 17 are respectively provided at the leading and trailing ends of the upper anchor plate 11 to improve the excavation capability, and a third excavation angle 18 is provided at the trailing end of the lower anchor plate 12 to correspond to the second excavation angle 17. The first excavation angle 16, the second excavation angle 17, and the third excavation angle 18 are all intended to increase the excavation capability of the upper and lower anchor plates 11, 12 and to increase the excavation depth.

[0042] Further optimizing the solution, in step 2, the double-layer flat plate bearing anchor 1 is tilted into the soil layer while being dragged along the head end, and the angle between the head end of the double-layer flat plate bearing anchor 1 and the horizontal plane gradually decreases until the head end of the double-layer flat plate bearing anchor 1 is in the same direction as the horizontal plane, at which point the dragging stops. When the double-layer flat plate bearing anchor 1 is dragged along the head end, the entire structure is drilled obliquely downward into the soil. The upper anchor plate 11 and the lower anchor plate 12 are pressed together due to the action of the soil pressure, and the hydraulic support rod 13 is shortened under the force. Therefore, during the embedding process, the upper and lower anchor plates 12 are embedded at a smaller angle. Compared with the original installation method with the opening forward, this installation method significantly reduces the influence of soil resistance, making the anchor plates easier to embed and ultimately able to embed to a deeper depth. After being embedded to a certain depth, the double-layer flat plate bearing anchor 1 is finally horizontal due to the tension of the anchor cable 15 and the soil pressure. If it is continued to be dragged, its embedding depth no longer changes, but maintains horizontal movement. At this time, it is the maximum diving depth.

[0043] To further optimize the solution, in step three, when the double-layer flat plate bearing anchor 1 is dragged in the reverse direction, the upper anchor plate 11 and the lower anchor plate 12 are respectively subjected to force, and the tail ends are deflected in the direction away from each other, and the hydraulic support rod 13 is stretched and lengthened. This step is mainly to open the angle between the anchor plates to exert their special bearing capacity. The main method is to reverse the dragging direction 180° after the first step is completed. At this time, the openings of the upper anchor plate 11 and the lower anchor plate 12 are facing the direction of movement. At this time, the soil resistance in the openings of the upper anchor plate 11 and the lower anchor plate 12 increases rapidly. Under the action of the soil resistance, the hydraulic support rod 13 connecting the upper and lower anchor plates 12 is stretched, and the opening angle between the anchor plates increases rapidly. When the hydraulic support rod 13 is fully pulled out, the angle reaches the set angle and no longer increases. At this time, the dragged embedded double-layer flat plate bearing anchor 1 is converted into a load-bearing state, and the installation is completed.

[0044] A method for installing and embedding a double-layer flat plate bearing anchor into a track marking comprises the following steps:

[0045] Step 1: Install the marking device 2; install the marking device 2 into the double-layer flat plate bearing anchor 1 so that the bottom end of the marking device 2 extends out of the lower end surface of the double-layer flat plate bearing anchor 1; install the marking device 2 between the upper anchor plate 11 and the lower anchor plate 12, so that the marking device 2 is fixed on the lower anchor plate 12, passes through and extends out of the lower anchor plate 12, so as to leave a track mark when the double-layer flat plate bearing anchor 1 is dragged;

[0046] Step 2: Add marking ink 4; Add marking ink 4 to the marking device 2; Add marking ink 4 to the marking device 2 for trajectory marking; the motion trajectory of different types of drag anchors can also be obtained by replacing the marking ink 4 with different colors, and the embedding trajectories of different types of anchors can be compared at the same time after all the tests are completed to study the effects of changes in the initial anchor plate angle (for example, 10°, 20°, 30°, etc.) and the length ratio of the upper anchor plate 11 and the lower anchor plate 12 (the length of the upper anchor plate 11 and the lower anchor plate 12 is 1:1, 3:2, 2:1, etc.) on the movement of the anchor plates during installation, providing a new method for studying the trajectory of the double-layer flat plate bearing anchor 1;

[0047] Step 3: Prepare the test equipment 3; prepare the test equipment 3 for easy observation and install the double-layer flat plate anchor 1 on the test equipment 3; the test equipment 3 is used to simulate the actual seabed environment to facilitate observation and recording of the embedding trajectory of the double-layer flat plate anchor 1;

[0048] Step 4: Drag test; drag the double-layer flat plate bearing anchor 1 along the direction of the head end thereof, so that the double-layer flat plate bearing anchor 1 is excavated into the test equipment 3; the test equipment 3 is used to simulate the actual seabed environment, so as to facilitate observation and recording of the embedding trajectory of the double-layer flat plate bearing anchor 1; drag the double-layer flat plate bearing anchor 1 according to step 2 of the installation method of the double-layer flat plate bearing anchor 1, so that the double-layer flat plate bearing anchor 1 is embedded into the test equipment 3; during the embedding process, the test equipment 3 and the marking device 2 interact with each other, so that the marking ink 4 in the marking device 2 flows out and is distributed according to the moving trajectory of the double-layer flat plate bearing anchor 1;

[0049] Step 5: Observe and record the embedment trajectory; observe and record the trajectory left by the marking device 2 within the test equipment 3. Observe the trajectory of the marking ink 4 left by the marking device 2 on the double-layer slab anchor 1. Comparative tests can be conducted using different models of double-layer slab anchors 1 and different colors of marking ink 4 to study the factors that affect the embedment depth of the double-layer slab anchor 1 during installation.

[0050] To further optimize the solution, the marking device 2 includes an ink storage tank 21 fixedly mounted on the top of the lower anchor plate 12, and the bottom end of the ink storage tank 21 is fixedly connected to the ink tank bottom plate 22, and the ink tank bottom plate 22 is embedded and fixed in the lower anchor plate 12; the bottom end of the ink tank bottom plate 22 is fixedly connected to an ink outlet assembly, and the ink outlet assembly extends out of the bottom end of the lower anchor plate 12; the ink outlet assembly includes an ink outlet port 23 fixedly connected to the bottom end of the ink tank bottom plate 22, and the ink outlet port 23 extends out of the lower anchor plate 12; the outlet of the ink outlet port 23 is detachably connected to a rotating ball 24, the bottom end of the rotating ball 24 extends out of the ink outlet port 23, the top end of the rotating ball 24 abuts against a top ball spring 25, and the top end of the top ball spring 25 is fixed to the top end of the inner cavity of the ink storage tank 21. The ink storage tank 21 is used to store marking ink 4, and the marking ink 4 can be injected into the ink storage tank 21 using a needle through the rubber hole (not shown in the figure) above the ink storage tank 21; the bottom surface of the ink outlet 23 is flush with the bottom surface of the lower anchor plate 12 and is closed, and the rotating ball 24 is slidably connected to the ink outlet 23, and its lower part extends out of the ink outlet 23 and blocks the outlet of the ink outlet 23; when the double-layer flat plate bearing anchor 1 is embedded in the ground, the part of the rotating ball 24 that leaks out of the lower anchor plate 12 due to the action of soil pressure is squeezed and rotates as the lower anchor plate 12 moves under the action of friction. Because the rotating ball 24 is squeezed and rises, and the top ball spring 25 is compressed and deformed, the marking ink 4 flows out evenly along the gap between the edge of the rotating ball 24 and the ink outlet 23 as the rotating ball 24 rotates, leaving a dyed track when the lower anchor plate 12 moves.

[0051] To further optimize the solution, the test equipment 3 includes a transparent test container 31 filled with a transparent filler 32. A guide rail 33 is fixed to the top of the test container 31. The anchor cable 15 fixed to the double-layer flat plate bearing anchor 1 passes through the guide rail 33 and is connected to a winch 34. The transparent container and transparent filler 32 of the test equipment 3 are selected to facilitate observation, reduce interference, and make the trajectory more obvious. The winch 34 pulls the double-layer flat plate bearing anchor 1 through the guide rail 33, simulating actual pulling and dragging. The guide rail 33 is mainly used to limit the anchor cable 15. At the same time, several internal wheels are installed on the track to reduce friction between the anchor cable 15 and the track and can reverse the anchor cable 15.

[0052] Furthermore, the filler 32 is preferably transparent soil or transparent sand, which is more convenient and intuitive.

[0053] To further optimize the solution, in step five, after observing that the double-layer flat anchor 1 is level, the double-layer flat anchor 1 is lifted upward, causing the rotating ball 24 to rebound without being stressed, sealing the ink outlet 23. When the test reaches the limit depth, the double-layer flat anchor 1 is pulled upward briefly and then released. This releases the bottom of the lower anchor plate 12 from the filler 32, reducing the pressure of the filler 32 on the rotating ball 24. The rotating ball 24 is then pressed against the ink outlet 23 again by the force of the extrusion spring, and the marking ink 4 stops flowing out.
