Description

Technical Field

[0001] The invention relates to the technical field of pile foundation testing, in particular to a device for testing the bearing capacity of a seabed pile foundation. Background Art

[0002] As deep-sea energy development and marine infrastructure construction activities are continuously carried out, submarine landslides are one of the core issues restricting marine development. Submarine landslides refer to the shear failure of unstable sediments on the submarine slope along a certain sliding surface under the action of their own weight and external loads such as earthquakes and waves, resulting in local or large-scale instability and downward sliding. Under the action of the self-weight stress field, the pore water pressure of the submarine sediments continues to accumulate with wave loads or seismic waves. When the shear stress exceeds the shear strength of the sediment, an initial shear surface is formed. Subsequently, the landslide body accelerates along the slope driven by gravitational potential energy, and the movement mode transforms from block sliding to debris flow. The movement distance can reach hundreds of kilometers. As the energy dissipates, the debris flow gradually slows down and forms an accumulation at the toe of the slope. Once a submarine landslide occurs, it is likely to cause damage to infrastructure, especially submarine pipelines and submarine pile foundations. When the landslide body impacts the submarine pile foundation, multi-scale damage will occur, triggering complex fluid-solid coupling effects. Therefore, clarifying the dynamic mechanism of submarine landslide movement and revealing the bearing capacity of submarine pile foundations during landslide movement are core issues in improving marine disaster risk management capabilities and reducing human and material losses.

[0003] The seabed environment is complex and dangerous, and the hydrogeological conditions are changeable. Most in-situ tests are time-consuming, labor-intensive, or even impossible to implement. In this case, the simulation experiment device has many advantages such as simplicity, speed, and freedom. After the simulation test is completed, the mud and water mixture inside the simulation box needs to be discharged from the box to provide conditions for the next simulation. However, after the simulation is completed, the mud and water mixture inside the simulation box cannot be discharged from the simulation box in time, which will cause the mud and water mixture to settle in the simulation box. It is difficult to separate the precipitated mud and water, especially the dense sediment layer, which needs to be manually scraped, flushed, or cleaned with the help of mechanical tools, which greatly increases the equipment maintenance time after the experiment. If the sediment layer is thick, it may be necessary to disassemble the box components for cleaning, further extending the experimental cycle and reducing the experimental efficiency. Summary of the Invention

[0004] Purpose of the invention: The problem to be solved by the present invention is that the mud-water mixture cannot be discharged in time after the simulation is completed, resulting in the mud-water mixture settling in the simulation box and being difficult to clean.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described in detail below with reference to the accompanying drawings.

[0029] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0030] Example 1

[0031] Reference Figures 1-6 , which is the first embodiment of the present invention, provides a submarine pile foundation bearing capacity test device. The submarine pile foundation bearing capacity test device includes a test assembly 100, including a simulation box 101. A bearing plate 102 is provided in the simulation box 101. The bearing plate 102 is inclined. A wave-pushing plate 103 is provided inside the simulation box 101. During the simulation, a prefabricated soil block and foundation pile combination is placed on the top of the bearing plate 102, and then a certain amount of water is injected into the simulation box 101. At this time, the wave-pushing plate 103 can be used to simulate the reciprocating movement of the wave-pushing plate 103 to simulate the waves until the soil block is broken up and the foundation pile is knocked down to complete the simulation.

[0032] The wave-pushing board 103 is provided with a driving component 104, which includes a moving electromagnet and an electrostatic magnet. The wave-pushing board 103 is fixed to the moving electromagnet, and a control device is provided on the electrostatic magnet, which can control the two electromagnets to attract each other with the same poles or repel each other with opposite poles. When the two electromagnets repel each other with opposite poles, the moving electromagnet can drive the wave-pushing board 103 to push, so that the wave-pushing board 103 pushes the water to form waves and impact the soil blocks and foundation piles. When the two electromagnets attract each other with the same poles, the moving electromagnet will drive the wave-pushing board 103 to move and reset, and can generate waves again.

[0033] The simulation box 101 is provided with a support track inside, and pulleys are provided on both sides of the moving electromagnet. The pulleys slide in the support track, and the moving electromagnet is supported by the pulleys.

[0034] Earth pressure gauges (not shown in the figure) are installed at the bottom of the foundation pile and the surface of the soil block, and each is placed on both sides of the pile facing the soil and the back of the soil. Strain gauges (not shown in the figure) are installed at the bottom of the foundation pile, the surface of the soil block and the top of the foundation pile, and each is placed on both sides of the pile facing the soil and the back of the soil. The strain gauges and earth pressure gauges are used to measure the changes in the soil block and the foundation pile caused by the impact of waves.

[0035] A support frame is fixed on the top of the simulation box 101, and high-speed cameras are fixed on one side and the bottom of the support frame respectively, so that users can shoot the changes of soil blocks and foundation piles in real time.

[0036] A rotatable wave-breaking plate is provided inside the simulation box 101 . The wave-breaking plate is driven by a motor and can eliminate the waves generated inside the simulation box 101 .

[0037] A drainage pipe 105 is provided at the bottom of the simulation box 101 . The bottom wall of the simulation box 101 is inclined, and the lowest point of the inclination is the top of the drainage pipe 105 , so that the mud-water mixture inside the simulation box 101 can be quickly discharged.

[0038] The auxiliary component 200 is arranged in the simulation box 101, and includes a cleaning part 201. The cleaning part 201 includes a scraper 2011 located on one side of the supporting plate 102. A connecting block 2012 is fixed on one side of the scraper 2011. There are two connecting blocks 2012, which are respectively fixed on both sides of the scraper 2011. A positioning block 2013 is fixed on one side of the supporting plate 102. There are four positioning blocks 2013, which are respectively fixed on the upper and lower sides of the supporting plate 102 in a group of two. A stabilizing column is fixed in the positioning block 2013 on the side opposite to the reciprocating roller 2014. The connecting block 2012 at the corresponding position is movably connected to the stabilizing column to prevent the scraper 2011 from offsetting when moving.

[0039] A reciprocating roller 2014 is rotatably connected to the positioning block 2013 via a bearing, and a fixed shaft 2015 is fixed in the connecting block 2012 , and the fixed shaft 2015 is engaged with the reciprocating roller 2014 .

[0040] When the soil blocks and foundation piles are washed away by the waves, the reciprocating roller 2014 will rotate and drive the connecting block 2012 and the scraper 2011 to move through the cooperation of the fixed shaft 2015, so that the scraper 2011 can clean the residual soil on the top of the supporting plate 102 and push the soil to the inlet of the drain pipe 105. At this time, the drain pipe 105 will open and the mud and water mixture inside the simulation box 101 will be discharged outward. In this way, the mud and water mixture can be discharged in time after the simulation is completed, avoiding the mud and water mixture from settling in the simulation box 101, which will cause subsequent difficulty in cleaning. The supporting plate 102 can also be cleaned to avoid the soil on the top of the supporting plate 102 from solidifying and requiring manual scraping, flushing or cleaning with the help of mechanical tools, thereby reducing the equipment maintenance time after the experiment.

[0041] Example 2

[0042] Reference Figures 3 to 7 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0043] Specifically, the auxiliary component 200 also includes a limiter 202, which includes a fixed frame 2021 fixed to one side of the supporting plate 102, a stopper 2022 is provided in the fixed frame 2021, a first spring 2023 is fixed to the bottom of the stopper 2022, and one side of the stopper 2022 is in contact with the connecting block 2012.

[0044] The setting of the block 2022 is used to block the connecting block 2012 and the scraper 2011 to prevent the scraper 2011 from moving during the simulation process, thereby affecting the normal simulation. The first spring 2023 is used to apply thrust to the block 2022 so that it can always be in contact with the connecting block 2012.

[0045] Specifically, the auxiliary component 200 also includes a rotating member 203, which includes a rotating sleeve 2031 rotatably connected to the outer side of the end of the reciprocating roller 2014. A coil spring 2032 is provided on one side of the positioning block 2013. The coil spring 2032 is provided inside the installation box. The installation box is fixed to the positioning block 2013, and the inner ring of the coil spring 2032 is fixed to the rotating sleeve 2031. When the rotating sleeve 2031 rotates, the coil spring 2032 can be tightened and energized.

[0046] A friction block is fixed to the outer side of the end of the rotating sleeve 2031 to facilitate the user to rotate the rotating sleeve 2031.

[0047] A movable groove 2014-1 is provided in the reciprocating roller 2014, and a clamping block 2033 is provided in the movable groove 2014-1. One side of the clamping block 2033 is inclined, and a second spring 2034 is fixed to one side of the clamping block 2033. A clamping slot 2031-1 is provided in the rotating sleeve 2031, and the clamping block 2033 is engaged with the clamping slot 2031-1. The rotating sleeve 2031 is connected to the reciprocating roller 2014 through the cooperation of the two, so that when the rotating sleeve 2031 is tightened with the coil spring 2032, it will not drive the coil spring 2032 to rotate. When the coil spring 2032 releases the torsional force and drives the rotating sleeve 2031 to rotate in the opposite direction, the reciprocating roller 2014 can be driven to rotate through the cooperation of the clamping block 2033 and the clamping slot 2031-1.

[0048] The second spring 2034 is used to apply a thrust to the clamping block 2033 so that the clamping block 2033 and the clamping slot 2031 - 1 are more tightly engaged. There are multiple clamping slots 2031 - 1 , which are evenly distributed in a ring shape on the inner side of the rotating sleeve 2031 .

[0049] Specifically, the auxiliary component 200 also includes a pushing member 204, which includes a push rod 2041 located on one side of the supporting plate 102, a positioning frame fixed to one side of the supporting plate 102, the push rod 2041 is movably connected to the positioning frame, a force groove 2022-1 is provided on the stop block 2022, and the inner wall of the force groove 2022-1 is inclined, a force block 2042 is fixed to one side of the push rod 2041, one side of the force block 2042 is inclined, and an extrusion rod 2043 is provided on one side of the force block 2042, and a positioning frame is also fixed to the bottom of the supporting plate 102, and the extrusion rod 2043 is movably connected to the positioning frame.

[0050] When the extrusion rod 2043 moves, it will squeeze the inclined surface of the force block 2042, and push the force block 2042 and the push rod 2041 to move, so that the end of the push rod 2041 is squeezed against the inner wall of the force groove 2022-1. Through the cooperation of the two, the stop block 2022 is driven to move, so that the stop block 2022 is separated from the connecting block 2012, thereby releasing the restriction on the connecting block 2012, and when the coil spring 2032 releases the torsional force, the connecting block 2012 can be moved.

[0051] Specifically, the auxiliary component 200 also includes a trigger member 205, which includes a movable plate 2051 located inside the supporting plate 102. A chamber is opened on the supporting plate 102, and the movable plate 2051 is movably connected to the chamber. When the soil block is placed on the top of the supporting plate 102, it is placed on the top of the movable plate 2051, and pressure is applied to the movable plate 2051 to make it enter the chamber.

[0052] A fixing column 2052 is fixed to one side of the movable plate 2051. One end of the fixing column 2052 passes through the bottom of the supporting plate 102 and is movably connected to the supporting plate 102. An extrusion block 2053 is fixed to one side of the fixing column 2052. One side of the extrusion block 2053 is inclined.

[0053] When the soil on the top of the movable plate 2051 is dispersed and sufficient pressure cannot be applied to the movable plate 2051, the movable plate 2051 will move upward and drive the fixed column 2052 and the squeezing block 2053 to move upward, so that the squeezing block 2053 can squeeze the squeezing rod 2043 at an angle and push the squeezing rod 2043 to move.

[0054] When the movable plate 2051 moves upward to a specified position, it stops moving. At this time, the bottom of the scraper 2011 is just flush with the top of the movable plate 2051. Therefore, the scraper 2011 cleans the top of the movable plate 2051 when it moves.

[0055] Specifically, a positioning column 2054 is fixed to one side of the movable plate 2051, a mounting block 2055 is fixed to the end of the positioning column 2054, a third spring 2056 is fixed to one side of the mounting block 2055, and the other end of the third spring 2056 is fixed to the supporting plate 102. There are four groups of the above structure, which are respectively located at the four corners of one side of the movable plate 2051.

[0056] When the soil on the top of the movable plate 2051 is dispersed, the third spring 2056 can apply a pulling force to the installation block 2055, and the installation block 2055 can drive the positioning column 2054 and the movable plate 2051 to move upward.

[0057] Example 3

[0058] Reference Figures 8-10 , which is the third embodiment of the present invention, is based on the first two embodiments.

[0059] Specifically, a sealing member 106 is provided in the drain pipe 105. The sealing member 106 includes a fixing ring 1061 fixed inside the drain pipe 105. A sealing plate 1062 is provided at the bottom of the fixing ring 1061. The sealing plate 1062 is used to seal the drain pipe 105 to prevent the water inside the simulation box 101 from being discharged outward during the simulation process.

[0060] A positioning plate 1063 is fixed to one side of the sealing plate 1062, a stabilizing block 1064 is fixed to the bottom of the fixing ring 1061, a connecting shaft 1065 is fixed inside the positioning plate 1063, and the connecting shaft 1065 is movably connected to the stabilizing block 1064. The three cooperate to hinge the sealing plate 1062 to the bottom of the fixing ring 1061, and a torsion spring 1066 is fixed to the outside of the connecting shaft 1065, and the other end of the torsion spring 1066 is fixed to the stabilizing block 1064. The torsion spring 1066 applies an upward torsional force to the connecting shaft 1065, so that the sealing plate 1062 can be closed upward after it is opened and the water inside the simulation box 101 is drained.

[0061] Specifically, the test assembly 100 also includes a locking piece 107, which includes a fixing rod 1071 fixed to the top of the blocking plate 1062. A slot 1072 is provided on the fixing rod 1071, and a limiting rod 1073 is inserted into the slot 1072. The fixing rod 1071 and the blocking plate 1062 are locked by cooperation of the two, so that the blocking plate 1062 will not open downward after being subjected to water pressure.

[0062] A pull rope 1074 is fixed to one side of the limiting rod 1073, and the other end of the pull rope 1074 is fixed to the push rod 2041. When the push rod 2041 moves, the pull rope 1074 can drive the limiting rod 1073 to move, and the limiting rod 1073 can be separated from the slot 1072, thereby releasing the restriction on the fixing rod 1071 and the blocking plate 1062.

[0063] Specifically, a stabilizing frame 1075 is fixed to the inner wall of the simulation box 101, and the limiting rod 1073 is movably connected to the stabilizing frame 1075 to position the limiting rod 1073 to prevent the limiting rod 1073 from deflecting when moving.

[0064] A first fixed block 1076 is fixed to the top of the stabilizing frame 1075, a second fixed block 1077 is fixed to the top of the limiting rod 1073, and a fourth spring 1078 is fixed between the first fixed block 1076 and the second fixed block 1077. The fourth spring 1078 is used to apply a thrust to the second fixed block 1077 and the limiting rod 1073 so that the limiting rod 1073 can be reset after moving.

[0065] Specifically, the test assembly 100 also includes an adjusting part 108, which includes a support frame 1081 fixed to the bottom wall of the simulation box 101, a support rod 1082 inserted in the support frame 1081, a slide rail 1083 fixed to the bottom of the supporting plate 102, and a sliding shaft 1084 fixed to one side of the support rod 1082. The sliding shaft 1084 slides in the slide rail 1083. The support rod 1082 is connected to the supporting plate 102 through the cooperation of the two. When the support rod 1082 moves up and down, the inclination angle of the supporting plate 102 can be adjusted.

[0066] A groove is provided inside the support rod 1082, and an insertion rod is provided in the groove. A fifth spring is fixed on one side of the insertion rod. A plurality of insertion holes are provided on the support frame 1081, and the insertion rod and the insertion hole are engaged. The height of the support rod 1082 can be locked by the cooperation of the two, thereby locking the height of the supporting plate 102. The fifth spring is used to apply thrust to the insertion rod.

[0067] During use, the prefabricated soil block and foundation pile combination is placed on the top of the bearing plate 102 and the movable plate 2051. The soil block will exert pressure on the movable plate 2051, causing the movable plate 2051 to move downward, and then the rotating sleeve 2031 is twisted to tighten the coil spring 2032 to charge it. After that, a certain amount of water is injected into the simulation box 101. At this time, the two electromagnets can be controlled by the control device to attract each other with like poles or repel each other with opposite poles. When the two electromagnets repel each other with opposite poles, the moving electromagnet can drive the wave pushing plate 103 to push, so that the wave pushing plate 103 pushes the water to form waves and impact the soil block and the foundation pile. When the two electromagnets attract each other with like poles, the moving electromagnet will drive the wave pushing plate 103 to move and reset, and can generate waves again, thereby simulating the impact of waves on the foundation pile.

[0068] When the soil on the top of the movable plate 2051 is dispersed and sufficient pressure cannot be applied to the movable plate 2051, the third spring 2056 applies a pulling force to the mounting block 2055, and the mounting block 2055 drives the positioning column 2054 and the movable plate 2051 to move upward, and the movable plate 2051 drives the fixed column 2052 and the extrusion block 2053 to move upward, so that the extrusion block 2053 can squeeze the extrusion rod 2043 at an angle and push the extrusion rod 2043 to move.

[0069] When the extrusion rod 2043 moves, it will squeeze the inclined surface of the force block 2042, and push the force block 2042 and the push rod 2041 to move, so that the end of the push rod 2041 squeezes the inner wall of the force groove 2022-1. Through the cooperation of the two, the stop block 2022 is driven to move, so that the stop block 2022 is separated from the connecting block 2012, thereby releasing the restriction on the connecting block 2012. At this time, the torsional force of the coil spring 2032 can be released, and drive the rotating sleeve 2031 and the reciprocating roller 2014 to rotate.

[0070] At the same time, when the push rod 2041 moves, the limit rod 1073 can be driven to move through the pull rope 1074, and the limit rod 1073 can be separated from the slot 1072, thereby releasing the restriction on the fixing rod 1071 and the blocking plate 1062. After being subjected to water pressure, the blocking plate 1062 will open downward.

[0071] At the same time, when the reciprocating roller 2014 rotates, it will drive the connecting block 2012 and the scraper 2011 to move through the cooperation of the fixed shaft 2015, so that the scraper 2011 can clean the residual mud on the top of the movable plate 2051 and push the mud to the inlet of the drain pipe 105. At this time, the drain pipe 105 will open and the mud-water mixture inside the simulation box 101 will be discharged outward. In this way, the mud-water mixture can be discharged in time after the simulation is completed, avoiding the mud-water mixture from settling in the simulation box 101, which will cause subsequent difficulty in cleaning. The supporting plate 102 can also be cleaned to avoid the mud on the top of the supporting plate 102 from solidifying and requiring manual scraping, flushing or cleaning with the help of mechanical tools, thereby reducing the equipment maintenance time after the experiment.
