Description

Technical Field

[0001] The invention relates to the technical field of pile foundation bearing capacity detection, in particular to a remote-controlled pile foundation bearing capacity detection device. Background Art

[0002] The foundation of offshore wind turbines is a very important part of offshore wind power projects. The cost of the foundation can account for 15%-45% of the total investment. There are various forms of offshore wind turbine foundations. In shallow water areas, there are mainly suction caissons and gravity foundations. In medium water depths, single pile foundations are mainly single pile foundations. Compared with other foundations, single pile foundations are more convenient to produce and construct, have lower costs, and simple structures. Unlike onshore pile foundations, offshore single pile foundations, in addition to bearing the vertical loads of the superstructure, must also withstand horizontal cyclic loads from wind and waves and the bending moments generated by them. The horizontal bearing capacity of the pile body is often the most important consideration in the design of offshore single piles.

[0003] The single pile horizontal static load test is used to determine the horizontal bearing capacity of a single pile and the horizontal resistance coefficient of the foundation soil, or to test and evaluate the horizontal bearing capacity of engineering piles. The test method is close to the actual working conditions and can reflect the various factors that affect the bearing capacity of the pile. The obtained bearing capacity value and the horizontal resistance coefficient of the foundation soil are most consistent with the actual situation. The test results can be used to test the strength of the pile body and deduce the elastic foundation coefficient at different depths.

[0004] The traditional single pile horizontal static load test usually uses a horizontal jack to apply a horizontal load. A spherical hinge is installed at the contact point between the jack and the test pile to ensure that the jack's force can pass horizontally through the axis of the pile body. During the test, the test pile tilts or bends as the horizontal load increases, resulting in unbalanced force on the spherical hinge. The spherical hinge is prone to shifting on the test pile. In extreme cases, the spherical hinge will detach from the test pile, affecting the accuracy of the test results and posing a greater safety hazard. Summary of the invention

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0037] Example 1

[0038] See also Figure 1-Figure 4In an embodiment of the present invention, a remote-controlled pile foundation bearing capacity detection device is used to test the horizontal bearing capacity of a single offshore pile and the horizontal compressive strength of foundation soil. In this embodiment, the foundation soil is a seabed. The remote-controlled pile foundation bearing capacity detection device includes a side beam 10, a clamping seat 20 for connecting a pile foundation 30, and a stabilizing mechanism. A first lifting beam 11 and a second lifting beam 12 are slidably mounted on the side beam 10. A manipulator 13 and a horizontal pulling mechanism 14 are mounted on the first lifting beam 11. The manipulator 13 is used to grab the pile foundation 30 to insert the pile foundation 30 into the foundation soil. The horizontal tension mechanism 14 is connected to the clamping seat 20. The horizontal tension mechanism 14 applies horizontal tension to the pile foundation 30 by pulling the clamping seat 20. The horizontal tension mechanism 14 includes a winding roller, a tension line wound on the winding roller, and a winding motor for controlling the rotation of the winding roller. The winding motor drives the winding roller to rotate, so that the winding roller drives the pile foundation 30 equipped with the clamping seat 20 to tilt through the tension line. The horizontal tension mechanism 14 can also adopt a jack in the prior art. When the horizontal tension mechanism 14 is a jack, the clamping seat 20 adopts a ball joint, and the ball joint is installed at the top of the pile foundation 30 in actual use.

[0039] In addition, it should be noted that a first hydraulic rod and a second hydraulic rod are installed on the side beam 10, wherein the telescopic end of the first hydraulic rod is connected to the first lifting beam 11, and the telescopic end of the second hydraulic rod is connected to the second lifting beam 12, and the first hydraulic rod and the second hydraulic rod are respectively used to adjust the heights of the first lifting beam 11 and the second lifting beam 12. When the manipulator 13 inserts the pile foundation 30 into the foundation soil, the first hydraulic rod controls the first lifting beam 11 to descend. After the pile foundation 30 is installed, the manipulator 13 is separated from the pile foundation 30, and the first hydraulic rod controls the first lifting beam 11 to rise. Since the first hydraulic rod and the second hydraulic rod are both existing technologies, the structure and connection method of the first hydraulic rod and the second hydraulic rod are omitted in the accompanying drawings.

[0040] The stabilizing mechanism includes an adjusting mechanism 40 connected to the second lifting beam 12, the adjusting mechanism 40 includes a top seat 41, a base 42 and a side plate connecting the top seat 41 and the base 42, the top seat 41 is fixedly connected to the second lifting beam 12 through a connecting member, and the side plate is as shown in FIG. Figure 1 As shown, Figure 3 and Figure 4The side panels are omitted in order to highlight the components between the top seat 41 and the base 42; a through hole is provided at the center of the top seat 41 and the base 42 for the pile foundation 30 to pass through, and a first limit block 43 and a second limit block 44 are respectively provided on both sides of the through hole on the top seat 41, wherein the first limit block 43 is fixedly connected to the top seat 41, and the second limit block 44 is slidably connected to the top seat 41. It is worth noting that the diameter of the through hole is larger than the diameter of the pile foundation 30, and the through hole does not contact the pile foundation 30 during the detection process, so as to avoid affecting the lateral displacement of the pile foundation 30; a sliding block 45 is also slidably installed on the top seat 41, and the sliding block 45 is slidably connected to the top seat 41. The second limit block 44 is fixedly connected. It can be understood that when the horizontal tension mechanism 14 drives the pile foundation 30 to tilt toward one side of the second limit block 44, the pile foundation 30 squeezes the second limit block 44, so that the second limit block 44 and the sliding block 45 slide on the top seat 41; a rack 451 and a driven gear 46 are provided at the bottom of the top seat 41, the rack 451 is fixedly connected to the sliding block 45, the driven gear 46 is rotatably installed on the top seat 41, and the driven gear 46 is meshed with the rack 451; a winding roller is also provided at the bottom of the top seat 41, and the winding roller is coaxially arranged with the driven gear 46. Figure 5 In the figure, the winding roller is blocked by the driven gear 46 and is not shown. A connecting rope is wound around the winding roller, and the connecting rope is connected to the clamping seat 20. It can be understood that when the sliding block 45 slides on the top seat 41, the rack 451 drives the driven gear 46 to rotate, so that Figure 5 For example, the rotation direction of the driven gear 46 is clockwise, and the driven gear 46 in the clockwise rotation state drives the connection rope to tighten, so that the connection rope pulls the clamping seat 20, preventing the clamping seat 20 from being displaced in the direction of the pile foundation 30 during the measurement process, avoiding the change of the force position of the pile foundation 30, reducing the measurement error of the horizontal bearing capacity, and preventing the clamping seat 20 from being separated from the pile foundation 30 during the tensile test of the pile foundation 30. In the embodiment of the present application, a guide roller 48 is also rotatably installed at the bottom of the top seat 41, and the guide roller 48 is used to guide the connection rope; in addition, a reset mechanism, such as a torsion spring, is also provided on the rotating shaft of the winding roller and the driven gear 46. During the test, the torsion spring is deformed by force. After the test is completed, the torsion spring returns to its initial state, thereby driving the winding roller and the driven gear 46 to reset.

[0041] In Example 1, after the side beams 10, the clamping seat 20, the pile foundation 30 and the adjustment mechanism 40 are installed, the single pile horizontal bearing capacity test of the pile foundation 30 and the horizontal compressive resistance test of the foundation soil can be carried out. In this embodiment, the displacement of the compression side of the foundation soil represents the magnitude of the horizontal compressive resistance of the foundation soil, and the displacement of the compression side of the foundation soil is negatively correlated with the magnitude of the horizontal compressive resistance of the foundation soil. When the displacement of the compression side of the foundation soil is larger, the horizontal compressive resistance of the foundation soil is smaller. In this embodiment, the single pile horizontal bearing capacity test adopts the single pile horizontal static load test method disclosed in the "Technical Specifications for Testing of Building Foundation Piles" (JGJ 106-2014) to test the ultimate horizontal bearing capacity of the pile foundation 30, and measures the displacement of the compression side of the foundation soil during the test. In the test, the single pile horizontal bearing capacity adopts a gradient setting, and the load gradient is selected according to actual conditions.

[0042] Example 2

[0043] For offshore single pile foundation, with the increase of the number of horizontal cyclic loads, the foundation soil on the pile side will experience repeated accumulation and dissipation of pore water pressure, resulting in a continuous decrease in the stiffness of the foundation soil on the pile side. The cyclic load will also cause a gap to form at the contact point between the pile and the shallow soil, greatly reducing the horizontal load stiffness of the pile foundation 30 and the foundation soil as a whole. In order to test how to improve the horizontal compressive capacity of the foundation soil and increase the horizontal load stiffness of the pile foundation 30 and the foundation soil as a whole, please refer to Figure 5-9 In this embodiment, the stabilizing mechanism also includes a reinforcing mechanism 50, which includes a mounting seat 51 and a plurality of reinforcing plates 53 arranged at the bottom of the mounting seat 51. A plurality of moving blocks 52 are arranged on the upper side of the mounting seat 51. The moving blocks 52 are slidably connected to the mounting seat 51. The number of moving blocks 52 and the reinforcing plates 53 is the same, and the moving blocks 52 are fixedly connected to the reinforcing plates 53. When the moving blocks 52 slide on the mounting seat 51, the moving blocks 52 drive the reinforcing plates 53 to move synchronously. In this embodiment, the moving direction of the reinforcing plates 53 is toward the pile foundation 30. When the reinforcing plates 53 move toward the pile foundation 30, the reinforcing plates 53 reinforce the foundation soil on the pile side to improve the stiffness of the foundation soil.

[0044] It should be noted that before the test, the reinforcement mechanism 50 is pre-installed in the foundation soil. After the reinforcement mechanism 50 is installed, the bottom of the mounting seat 51 is flush with the surface of the foundation soil, and the reinforcement plate 53 is distributed on the surrounding side of the pile foundation 30. The soil between the reinforcement plate 53 and the pile foundation 30 is the pile side foundation soil. In addition, since the bottom of the mounting seat 51 is flush with the surface of the foundation soil, when the pile foundation 30 shifts sideways, the friction between the bottom of the mounting seat 51 and the foundation soil is used to resist the horizontal load. At the same time, the pressure of the mounting seat 51 can also effectively prevent the scouring of the pile side soil and apply additional stress to the foundation soil below the mounting seat 51, thereby increasing the stiffness of the foundation soil.

[0045] Furthermore, in the embodiment of the present application, the base 42 is rotatably connected to the bottom of the side plate, and the upper part of the side plate is detachably connected to the top seat 41. A gear ring 47 is fixedly installed on the side of the base 42 facing the top seat 41, and the gear ring 47 is meshed with the driven gear 46. It can be understood that when the sliding block 45 slides on the top seat 41, the rack 451 drives the driven gear 46 to rotate, thereby driving the gear ring 47 and the base 42 to rotate; a plurality of top blocks 49 are fixedly installed on the bottom of the base 42, and the top blocks 49 correspond to the moving blocks 52 one by one. When the base 42 rotates, the top blocks 49 squeeze the moving blocks 52, so that the moving blocks 52 slide on the mounting seat 51, thereby driving the reinforcement plate 53 to slide. In this embodiment, the sliding direction of the reinforcement plate 53 is to slide toward the pile foundation 30, thereby clamping and fixing the foundation soil around the pile foundation 30, and increasing the horizontal load-bearing stiffness of the pile foundation 30 and the foundation soil as a whole.

[0046] It can be understood that by adjusting the height of the second side beam 10 through the second hydraulic rod in Example 1, the second side beam 10 drives the adjustment mechanism 40 to move toward the reinforcement mechanism 50 until the top block 49 contacts the moving block 52, and the moving block 52 can be pushed to move by the top block 49.

[0047] It should be noted that the top block 49 has a first inclined surface, and the moving block 52 has a second inclined surface that cooperates with the first inclined surface. The top block 49 drives the moving block 52 to slide on the base 42 through the mutual compression between the first inclined surface and the second inclined surface.

[0048] In Example 2, on the basis of Example 1, after the installation of the above-mentioned reinforcement mechanism 50 and the adjustment mechanism 40 is completed, the single pile horizontal bearing capacity test of the pile foundation 30 and the horizontal compressive resistance test of the reinforced foundation soil can be carried out. The test method also adopts the single pile horizontal static load test method disclosed in the "Technical Specifications for Building Foundation Pile Testing" (JGJ 106-2014) to test the ultimate horizontal bearing capacity of the pile foundation 30, and measure the displacement of the compressive side of the reinforced foundation soil during the test. In the test, the single pile horizontal bearing capacity adopts a gradient setting, and the load gradient is selected according to actual conditions.

[0049] Example 3

[0050] In the embodiments of the present application, Figure 5 as well as Fig. 9As shown, at least one grouting hole 521 is provided on the moving block 52, and a feed box 60 is fixedly installed on the second lifting beam 12. The feed box 60 stores reinforcement materials, such as cement, inside. The feed box 60 is connected to the grouting hole 521 through a feed pipe 61. When the reinforcement plate 53 slides, a gap is generated between the reinforcement plate 53 and the foundation soil. At this time, cement is filled into the gap between the reinforcement plate 53 and the foundation soil through the grouting hole 521 to improve the strength of the foundation soil, thereby improving the tensile strength of the pile foundation 30. In addition, it should be noted that the feed box 60 can be provided with a feed pump to deliver the cement inside the feed box 60 into the grouting hole 521 through the feed pipe 61.

[0051] In Example 3, after the reinforcement mechanism 50 and the adjustment mechanism 40 are installed, the single pile horizontal bearing capacity test of the pile foundation 30 and the horizontal compressive resistance test of the foundation soil after reinforcement and grouting can be carried out. The test method also adopts the single pile horizontal static load test method disclosed in the "Technical Specifications for Testing of Building Foundation Piles" (JGJ 106-2014) to test the ultimate horizontal bearing capacity of the pile foundation 30, and measures the displacement of the compressive side of the foundation soil after reinforcement and grouting during the test. The single pile horizontal bearing capacity adopts a gradient setting, and the load gradient is selected according to actual conditions.

[0052] Example 4

[0053] A remote-controlled pile foundation bearing capacity detection device further includes a remote testing module, wherein the remote testing module includes a data acquisition unit, a data processing unit, a remote transmission unit, and a mobile device, wherein:

[0054] A data acquisition unit is used to collect the test data of the pile foundation 30, wherein the test data includes horizontal tension data and displacement data of the compression side of the foundation soil. The horizontal tension data is collected using a tensile meter, and the displacement data is collected using a displacement sensor. It is worth noting that when collecting the horizontal tension data, the horizontal component force applied by the connecting rope to the clamping seat 20 should be removed;

[0055] A data processing unit for recording test data and generating a horizontal load displacement curve of foundation soil based on the test data;

[0056] Remote transmission unit for sending test data and horizontal load-displacement curves of foundation soil;

[0057] The mobile device is used to display the test data and the horizontal load-displacement curve of the foundation soil. It should be noted that the test ends when the pile foundation 30 breaks. The upper level load of the horizontal tension of the pile foundation 30 is the horizontal ultimate bearing capacity of the pile foundation 30. The horizontal tension test results of the pile foundation 30 are shown in Table 1:

[0058] Table 1

[0059]

[0060] It can be seen from Table 1 that in Example 2, after the foundation soil is reinforced, the horizontal ultimate bearing capacity of the pile foundation 30 is increased by 147%. In Example 3, after the foundation soil is reinforced and grouting is performed, the horizontal ultimate bearing capacity of the pile foundation 30 is increased by 169%. It can be seen that reinforcing the foundation soil and grouting can effectively improve the horizontal ultimate bearing capacity of the pile foundation 30.

[0061] In addition, the horizontal load displacement curve of the foundation soil is as follows Fig.10 As shown by Fig.10 It can be seen that in Example 2, after the foundation soil is reinforced, under the same horizontal tensile force, the displacement of the foundation soil is reduced compared with Example 1. In Example 3, after the foundation soil is reinforced and grouting is performed, under the same horizontal tensile force, the displacement of the foundation soil is reduced compared with Example 2. It can be seen that reinforcement and grouting of the foundation soil can effectively improve the stiffness of the foundation soil.

[0062] To summarize, during the pile foundation horizontal bearing capacity test, the present invention performs tension compensation on the connector connected to the pile foundation, thereby preventing the connector from being displaced along the pile foundation direction during the measurement process, avoiding changes in the force position of the pile foundation, reducing the measurement error of the horizontal bearing capacity, and preventing the connector from being separated from the pile foundation during the pile foundation tension test; during the pile foundation horizontal bearing capacity test, the present invention reinforces and grouts the foundation soil, and tests the horizontal compressive capacity of the foundation soil after reinforcement and grouting as well as the overall stiffness of the pile foundation and the foundation soil, verifying that reinforcing and grouting the foundation soil can effectively improve the overall stiffness of the pile foundation and the foundation soil and enhance the horizontal bearing performance of the single pile foundation, and has practical engineering application value for offshore single pile foundations.
