[0037] Example 1
[0038] like Figure 1~Figure 4 As shown, this embodiment proposes a single pile compression and pull-out bearing capacity detection device, which is used to detect the compression performance or pull-out performance of the pile to be tested 100. The first side pile 200 and the second side pile 300 are required to be provided on both sides of the pile to be tested 100, including: a first pull rope 400 and a second pull rope 500, one end of the first pull rope 400 is connected to the first side pile 200, and one end of the second pull rope 500 is connected to the second side pile 300; a connecting member 600, the other end of the first pull rope 400 is connected to the connecting member 600, and the other end of the second pull rope 500 is connected to the connecting member 600; a top pressure member 700, which is arranged on the connecting member 600 and is used to pull up or press down the pile to be tested 100.
[0039] In this embodiment, one end of the first pull rope 400 and the second pull rope 500 are respectively connected to the first side pile 200 and the second side pile 300, and the other ends are connected to the connecting piece 600. The top pressure piece 700 acts between the connecting piece 600 and the pile to be inspected 100. After the top pressure piece 700 is extended, relative movement occurs between the connecting piece 600 and the pile to be inspected 100, the first pull rope 400 and the second pull rope 500 are stretched, and relative movement can no longer occur between the connecting piece 600 and the pile to be inspected 100. The top pressure piece 700 continues to extend, and a relative force is generated between the connecting piece 600 and the pile to be inspected 100. According to the change of the setting position of the connecting piece 600 and the top pressure piece 700 on the pile to be inspected 100, the pile to be inspected 100 is subjected to upper tension and lower pressure respectively. The top pressure piece 700 continues to act, and the upper tension and lower tension on the pile to be inspected 100 gradually increase. The connector 600, the first pull rope 400 and the second pull rope 500 are all arranged on the pile body, so that the compression and tension tests of the pile 100 to be tested can be realized without relying on the ground, and the pile body on the water surface does not need to go underwater.
[0040] Example 2
[0041] like Figure 1~2 As shown, based on Example 1, further, the connecting member 600 is slidably arranged on the pile to be inspected 100, and the two ends of the top pressure member 700 are respectively arranged between the connecting member 600 and the pile to be inspected 100, and the connection between the first pull rope 400 and the first side pile 200 and the connection between the second pull rope 500 and the second side pile 300 are both lower than the connecting member 600. After the top pressure member 700 acts, the pile to be inspected 100 is subjected to downward pressure. Further, the connecting member 600 has a positioning groove on one side close to the pile to be inspected 100.
[0042] In this embodiment, the connecting member 600 can be set as a steel structure member that can withstand pressure, such as an I-beam, a steel plate or a C-beam, and the top pressure member 700 can be set as a workpiece that can provide pressure, such as a hydraulic cylinder, a cylinder or a point pressure cylinder, and the first pull rope 400 and the second pull rope 500 are connected to the connecting member 600. The connecting member 600 is located above the pile to be inspected 100, and the top pressure member 700 is placed on the top of the connecting member 600 and the pile to be inspected 100. The connection between the first pull rope 400 and the second pull rope 500 and the first side pile 200 and the second side pile 300 is lower than The connecting piece 600 stretches the first pull rope 400 and the second pull rope 500, and the top pressure piece 700 acts between the top of the pile to be inspected 100 and the connecting piece 600. Under the action of the first pull rope 400 and the second pull rope 500, the position of the connecting piece 600 is fixed relative to the pile to be inspected 100. The force of the extended top pressure piece 700 acts on the top of the pile to be inspected 100, so that the pile to be inspected 100 is under pressure. The pressure of the top pressure piece 700 is gradually increased to the load pressure of the pile to be inspected 100, so as to detect whether the compressive strength of the pile to be inspected 100 meets the requirements.
[0043] Furthermore, it also includes: a plurality of longitudinal rods 612 , which are circumferentially spaced around the connecting member 600 , and the pile 100 to be inspected is located between the plurality of longitudinal rods 612 .
[0044] In this embodiment, the longitudinal rods 612 around the connecting piece 600 can cover the pile body of the pile to be inspected 100 in the middle, ensuring that the connecting piece 600 is raised and lowered in the axial direction of the pile to be inspected 100 to prevent the connecting piece 600 from being skewed. In addition, for some piles to be inspected 100 with higher heights, the longitudinal rods 612 can be used to lift the connecting piece 600 onto the pile to be inspected, and the positioning groove can be used to fix the top pressure piece 700 at the center of the pile to be inspected 100 and the connecting piece 600 to make the force more uniform.
[0045] Example 3
[0046] like Figure 3~4 As shown, on the basis of Example 1, it further includes: a fixing member 1200 is arranged on the pile body of the pile to be inspected 100; a connecting member 600 is slidably arranged on the pile body of the pile to be inspected 100, the connecting member 600 is located below the fixing member 1200, the connection points between the first pull rope 400 and the first side pile 200, and the connection points between the second pull rope 500 and the second side pile 300 are all higher than the connecting member 600, and a top pressure member 700 is arranged between the fixing member 1200 and the connecting member 600, and after the top pressure member 700 acts, the pile to be inspected 100 is subjected to the upward pulling force.
[0047] In this embodiment, the fixing member 1200 is fixed on the pile body of the pile to be inspected 100, the first pull rope 400 and the second pull rope 500 are connected to the connecting member 600, the connecting member 600 can slide on the pile body of the pile to be inspected 100, and the connecting member 600 is located below the fixing member 1200, the connection between the first pull rope 400 and the second pull rope 500 and the first side pile 200 and the second side pile 300 is higher than the connecting member 600, and the top pressure member 700 acts between the connecting member 600 and the fixing member 1200, so as to connect the first pull rope 400 and the second pull rope 500 to the pile body of the pile to be inspected. After the rope 500 is stretched tight, the pressure piece 700 acts between the connecting piece 600 and the fixing piece 1200. The connecting piece 600 is in a stationary state relative to the fixing piece 1200 under the action of the first pull rope 400 and the second pull rope 500. The force of the extension of the pressure piece 700 acts on the fixing piece 1200, and the fixing piece 1200 is subjected to an upward pulling force, thereby providing an upward pulling force for the pile 100 to be inspected. By increasing the pressure of the pressure piece 700 to the load pull-out force of the pile 100 to be inspected, it is possible to detect whether the pull-out resistance of the pile 100 to be inspected meets the requirements.
[0048] Furthermore, a plurality of bosses 623 are provided on the inner wall of the connecting member 600 , and the bosses 623 abut against the pile 100 to be inspected.
[0049] In this embodiment, the fixing member 1200 can be set as a workpiece such as a clamp that can be fixed on the pile body of the pile to be inspected 100, and the connecting member 600 can be set as a clamp with a boss on the inner ring or other workpiece that can slide on the pile to be inspected 100. When the connecting member 600 is set as a clamp, the fastening force of the connecting member 600 should not be too large, and it should be ensured that the connecting member 600 can slide on the pile body of the pile to be inspected 100. The boss 623 on the inner wall of the connecting member 600 reduces the friction between the connecting member 600 and the pile body of the pile to be inspected 100, making the connecting member 600 easier to slide and minimizing the damage to the pile body of the pile to be inspected caused by the sliding process of the connecting member 600.
[0050] Example 4
[0051] like Figures 1 to 4 As shown, it includes all the structures of Example 2 or Example 3. Further, there are third side piles 800 and fourth side piles 900 on both sides of the pile 100 to be inspected, and the third side piles 800 and the fourth side piles 900 are respectively located on the side of the first side pile 200 and the second side pile 300 away from the pile 100 to be inspected, and also includes: a third pull rope 1000, which has several parts and is used to connect the first side pile 200 and the third side pile 800 or the second side pile 300 and the fourth side pile 900 respectively.
[0052] In this embodiment, a third pull rope 1000 can be added to the third side pile 800 and the fourth side pile 900 on both sides of the first side pile 200 and the second side pile 300 away from the inspection pile 100. The third pull rope 1000 is respectively connected between the first side pile 200 and the third side pile 800 and between the second side pile 300 and the fourth side pile 900. The third pull rope 1000 can share the lateral force for the first side pile 200 and the second side pile 300, so that the first side pile 200 and the second side pile 300 are more stable, and prevent the first side pile 200 and the second side pile 300 from tipping over when subjected to the oblique force of the first pull rope 400 or the second pull rope 500.
[0053] Furthermore, it also includes: there are a plurality of hoops 1100 , and the first pull rope 400 , the second pull rope 500 and the third pull rope 1000 are all connected to the first side stake 200 , the second side stake 300 , the third side stake 800 and the fourth side stake 900 through the hoops 1100 .
[0054] In this embodiment, the clamp 1100 is fixed on the first side pile 200, the second side pile 300, the third side pile 800 or the fourth side pile 900, and the first pull rope 400, the second pull rope 500 and the third pull rope 1000 are all fixed on the fastener of the clamp 1100. The clamp 1100 is not only convenient for fixing on the pile body, but also removing the clamp 1100 after the inspection will not affect the subsequent use of the pile body. The pull rope is fixed on the fastener of the clamp 1100, which makes it more convenient to connect the pull rope.
[0055] Furthermore, the first pull rope 400 , the second pull rope 500 and the third pull rope 1000 all include: a steel wire rope 420 having two sections, one end of the steel wire rope 420 is arranged on the connector 600 or the clamp 1100 , and the other ends of the two sections of the steel wire rope 420 are connected together through a tensioner 410 .
[0056] In this embodiment, the first pull rope 400, the second pull rope 500 and the third pull rope 1000 are each divided into two sections of steel wire rope 420, and the two sections of pull rope are connected together by a tensioner 410. The tensioner 410 can adjust the length of the first pull rope 400, the second pull rope 500 and the third pull rope 1000 so that they can adapt to pile body detection with different spacing settings.
[0057] Furthermore, the third pull rope 1000 is connected to the first pull rope 400 or the second pull rope 500 on a clamp 1100 .
[0058] In this embodiment, the third pull rope 1000 is connected to the first pull rope 400 or the second pull rope 500 via a clamp 1100 on the first side stake 200 or the second side stake 300, which can not only make the force on the first side stake 200 or the second side stake 300 more uniform, but also save the number of clamps 1100 used, thereby improving the detection efficiency.
[0059] Furthermore, the third pull ropes 1000 are all arranged horizontally.
[0060] In this embodiment, the third pull rope 1000 is arranged horizontally, which can balance the horizontal force acting on the first side stake 200 or the second side stake 300 to the maximum extent.
[0061] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
