Description

Technical Field

[0001] The utility model relates to the field of building foundations, and particularly relates to an anti-floating anchor thorn device for a sonic logging tube of a plain concrete pile. Background Art

[0002] With the continuous progress of society, the construction industry is also developing rapidly. However, resources are constantly being consumed. In order to save social resources while rapidly developing the construction industry, various new processes emerge in an endless stream. For cohesive soil foundations, in order to ensure that the bearing stratum of buildings meets the requirements and save resources, the process of plain concrete pile foundations is being promoted everywhere. This process uses concrete piles without steel bars to compact the foundation to meet the bearing capacity requirements. However, the quality of plain concrete piles is crucial. Therefore, it is necessary to detect plain concrete piles. Among them, sonic logging requires burying sonic logging tubes. Therefore, the quality of sonic logging tubes is related to the acceptance results of pile foundations.

[0003] In the traditional method, after hanging heavy objects at the bottom of the sonic logging tube, workers stand at the hole opening and lower the sonic logging tube into the pile hole one by one. Since the wall thickness of the sonic logging tube is relatively thin, it is easy to be damaged during the lowering process after hanging heavy objects. The gravity of the hanging heavy objects often cannot ensure that it is greater than the buoyancy received by the sonic logging tube itself in the concrete, and usually there will be a floating phenomenon, ultimately resulting in unqualified sonic logging tests. It is necessary to take the core drilling method to further verify the quality of the pile foundation. In addition, manually placing the sonic logging tube at the hole opening has great safety hazards and low efficiency.

[0004] Therefore, developing an anti-floating anchor thorn device that can ensure the installation quality of sonic logging tubes and prevent them from floating, and avoid unqualified sonic logging tests, will be of great significance for green construction. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-floating anchor thorn device for a sonic logging tube of a plain concrete pile. The device is arranged on the outside of the sonic logging tube and can be retracted inward or expanded outward during the lowering or floating process of the sonic logging tube, so that the sonic logging tube can maintain stability during the diving installation process and ensure that the sonic logging tube is not damaged. At the same time, the sonic logging tube can use the buoyancy during the floating process to insert the anti-floating anchor thorns into the soil to offset the buoyancy, solving the problems of damage to the sonic logging tube of the plain concrete pile and floating of the sonic logging tube.

[0006] To achieve the above technical purpose, the utility model is realized through the following technical solutions:

[0007] An anti-floating anchor thorn device for a sonic logging tube of a plain concrete pile, comprising:

[0008] Sonic logging tubes, multiple of which are provided and can be buried in the hole of the plain concrete pile. Among them, the multiple sonic logging tubes are uniformly arranged along the inner edge of the horizontal hoop.

[0009] Anti-floating anchor spurs, the anti-floating anchor spurs include a rotating part and an anchor rod. One end of the rotating part is welded to the horizontal hoop, and the other end of the rotating part is a rotating end and is connected to the anchor rod. The rotating part enables the anchor rod to retract inward or expand outward during the lowering or floating of the sonic logging tube.

[0010] In this solution, multiple sonic logging tubes are evenly arranged along the inner edge of the horizontal hoop to form a columnar structure that matches the pile hole of the plain concrete pile. The rotating parts of the anti-floating anchor spurs are respectively connected to the horizontal hoop and the anchor rod. The rotating part enables the anchor rod to retract inward and abut against the inner wall surface of the pile hole during the installation of the sonic logging tube, thereby maintaining the stability of the sonic logging tube and ensuring that the sonic logging tube does not break. At the same time, the sonic logging tube can also use the upward buoyancy during the floating process to enable the anchor rod to expand outward, so that the anchor rod can be inserted into the soil on the inner wall surface of the pile hole during the floating process to offset the upward buoyancy and avoid the floating phenomenon, which ultimately leads to unqualified sonic testing.

[0011] As a further technical solution of the anti-floating anchor spur device, to further improve the anti-floating ability of the anti-floating anchor spur, the free end of the anchor rod extends obliquely upward to the horizontal hoop.

[0012] As a further technical solution of the anti-floating anchor spur device, to further maintain the stability of the sonic logging tube during the installation process, at least 3 sonic logging tubes are provided.

[0013] As a further technical solution of the anti-floating anchor spur device, to further maintain the stability of the sonic logging tube during the installation process, the anti-floating anchor spur device further includes vertical supports. At least three vertical supports are provided, and each vertical support is evenly arranged along the inner edge of the horizontal hoop, and each sonic logging tube is configured with the vertical support.

[0014] As a further technical solution of the anti-floating anchor spur device, to further maintain the stability of the sonic logging tube during the installation process, multiple horizontal hoops are arranged at intervals along the longitudinal direction of the sonic logging tube.

[0015] As a further technical solution of the anti-floating anchor spur device, to further improve the anti-floating ability of the anti-floating anchor spur, the anti-floating anchor spurs are provided at the horizontal hoops at the upper, middle, and lower parts of the sonic logging tube.

[0017] As a further technical solution of the anti-floating anchor spur device, the rotating part includes an upper hinge and a lower hinge;

[0018] One end of the upper hinge is horizontally welded to the horizontal hoop, and the other end of the upper hinge is connected to the lower hinge through a damping rotating shaft, and the anchor rod is connected to the lower hinge.

[0019] As a further technical solution of the anti-floating anchor spike device, the rotating part includes an upper support rod, an upper hinge, a lower support rod and a lower hinge;

[0020] One end of the upper hinge is horizontally welded to the horizontal hoop, the other end of the upper hinge is connected to the lower hinge through a rotating shaft, and the anchor rod is connected to the lower surface of the lower hinge;

[0021] Wherein, the upper support rod and the lower support rod are respectively connected to the upper surface and the lower surface of the upper hinge, the other ends of the upper support rod and the lower support rod are both free ends, the free end of the upper support rod faces the anchor rod, and the free end of the lower support rod faces the upper surface of the lower hinge. The upper support rod and the lower support rod are used to limit the anchor rod to prevent the anchor rod from interfering with the anti-floating anchor spike device during the retraction or deployment process.

[0022] As a further technical solution of the anti-floating anchor spike device, the free end of the upper support rod and the axis of the rotating shaft are in the same longitudinal plane, so that during the retraction process of the anchor rod, the maximum retraction angle is 90 degrees, and the extension line of the free end of the lower support rod intersects with the longitudinal plane of the axis of the rotating shaft, so that during the deployment process of the anchor rod, it always maintains a certain inclination angle.

[0024] 1. A plain concrete pile sonic logging tube anti-floating anchor spike device provided by the utility model includes a sonic logging tube and an anti-floating anchor spike. The rotating parts of the anti-floating anchor spike are respectively connected to a horizontal hoop and an anchor rod. The rotating part enables the anchor rod to retract inward and abut against the inner wall surface of the pile hole during the diving installation process of the sonic logging tube, thereby maintaining the stability of the sonic logging tube and ensuring that the sonic logging tube does not break. At the same time, the sonic logging tube can also use the upward buoyancy during the upward floating process to enable the anchor rod to expand outward, so that the anchor rod is inserted into the soil of the inner wall surface of the pile hole during the upward floating process to offset the upward buoyancy, avoiding the upward floating phenomenon and ultimately resulting in unqualified sonic testing.

[0032] To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in combination with embodiments and attached drawings. The illustrative embodiments of the present utility model and their descriptions are only used to explain the present utility model and do not limit the present utility model.

[0033] Embodiment 1

[0034] This Embodiment 1 provides a device for anti-floating anchor spikes of sonic logging tubes in plain concrete piles, as Figures 1 - 3 shown, including a sonic logging tube 2 and an anti-floating anchor spike 4;

[0035] Among them, multiple sonic logging tubes 2 are provided, and each sonic logging tube 2 is equipped with a vertical support 1. The multiple sonic logging tubes 2 are uniformly arranged along the inner edge of the horizontal hoop 3 to form a columnar structure matching the pile hole of the plain concrete pile, as Figure 2 shown. In this embodiment, 3 sonic logging tubes 2 are provided. In some embodiments, when the number of sonic logging tubes 2 is less than 3, in order to improve the strength of the entire device, at least 3 vertical supports 1 are still provided. When the number of sonic logging tubes is at least 3, the number of vertical supports 1 is the same as the number of sonic logging tubes 2.

[0036] In this embodiment, in order to further maintain the stability of the sonic logging tube 2 during the installation process, multiple horizontal hoops 3 are arranged at intervals along the longitudinal direction of the sonic logging tube 2. Specifically, a horizontal hoop 3 is arranged every 2 meters from top to bottom along the longitudinal direction of the sonic logging tube 2, and 3 anti-floating anchor spikes 4 are arranged every 4 meters along the longitudinal direction of the sonic logging tube 2. Of course, more can also be arranged for a better anti-floating effect. It should be noted that in order to ensure the anti-floating ability of the anti-floating anchor spike 4, anti-floating anchor spikes 4 must be provided at the horizontal hoops 3 at the upper, middle and lower parts of the sonic logging tube 2.

[0037] Among them, the anti-floating anchor thorn 4 includes a rotating part and an anchor rod 9. One end of the rotating part is welded to the horizontal hoop 3, and the other end of the rotating part is a rotating end and is connected to the anchor rod 9. The free end of the anchor rod 9 extends obliquely upward from the horizontal hoop 3. The rotating part enables the anchor rod 9 to retract inward or expand outward during the lowering or floating of the acoustic logging tube 2.

[0038] Specifically, please refer to Figure 3 As shown, the rotating part includes an upper support rod 5, an upper hinge 6, a lower support rod 7 and a lower hinge 8. One end of the upper hinge 6 is horizontally welded to the horizontal hoop 3, the other end of the upper hinge 6 is connected to the lower hinge 8 through a rotating shaft, and the anchor rod 9 is connected to the lower surface of the lower hinge 8.

[0039] Among them, the upper support rod 5 and the lower support rod 7 are respectively connected to the upper surface and the lower surface of the upper hinge 6. The connection points of the upper support rod 5 and the lower support rod 7 on the upper hinge 6 are in the same vertical plane. The other ends of the upper support rod 5 and the lower support rod 7 are both free ends. The free end of the upper support rod 5 faces the anchor rod 9, and the free end of the upper support rod 5 and the axis of the rotating shaft are in the same longitudinal plane, so that during the retraction process of the anchor rod 9, its maximum retraction angle is 90 degrees, so that it can automatically match the inner diameter of the bored pile during the diving installation process of the acoustic logging tube 2. The free end of the lower support rod 7 faces the upper surface of the lower hinge 8, and the extension line of the free end of the lower support rod 7 intersects the longitudinal plane of the axis of the rotating shaft, so that during the expansion process of the anchor rod 9, it always maintains a certain inclination angle. Therefore, during the floating process of the acoustic logging tube 2, the inclined anchor rod 9 can automatically insert into the soil on the inner wall surface of the bored pile to offset the upward buoyancy.

[0040] Embodiment 2

[0041] Based on the technical solution of Embodiment 1, this Embodiment 2 provides another anti-floating anchor thorn device for plain concrete pile acoustic logging tubes. As Figures 1 - 3 shown, the difference is that the rotating part includes an upper hinge 6 and a lower hinge 8. Among them, one end of the upper hinge 6 is horizontally welded to the horizontal hoop 3, the other end of the upper hinge 6 is connected to the lower hinge 8 through a damping rotating shaft, and the anchor rod 9 is connected to the lower hinge 8. The rotation angle of the anchor rod 9 is adjusted through the damping rotating shaft.

[0042] Another difference is that both ends of the vertical support 1 extend outward from the acoustic logging tube 2 to protect the acoustic logging tube 2 from being damaged during the installation process.

[0043] The construction process of the present utility model is as follows:

[0044] In the first step, the upper hinge 6 and the lower hinge 8 with dimensions of 100mm * 200mm * 2mm are adopted. Two short steel bars of C14 are welded to the upper and lower parts of the upper hinge 6 as the upper support rod 5 and the lower support rod 7. The length of the upper support rod 5 is 120mm, and the length of the lower support rod 7 is 70mm.

[0045] In the second step, a short steel bar of C14 with a length of 200mm is used as the anchor rod 9 and welded to the lower hinge 8 to form an anti-floating anchor spur member.

[0046] In the third step, a horizontal hoop 3 is welded with C18 steel bars. The outer diameter is 100mm smaller than the drilling diameter of the plain concrete pile. The anti-floating anchor spur 4 is horizontally welded to the horizontal hoop 3. On each horizontal hoop 3, three anti-floating anchor spurs 4 are welded at equal intervals.

[0047] In the fourth step, C18 steel bars are used as the vertical supports 1 and welded to the horizontal hoop 3 at equal intervals. At least three vertical supports 1 are provided. If there are more than three sonic logging tubes 2, the number of vertical supports 1 is the same as the number of sonic logging tubes 2. A horizontal hoop 3 is arranged every 2 meters, and three anti-floating anchor spurs 4 are arranged every four meters, but it is necessary to ensure that there are anti-floating anchor spurs 4 at the upper, middle and bottom of the sonic logging tube 2.

[0048] In the fifth step, the sonic logging tubes 2 are successively tied to the vertical supports 1 with iron wires, and the tying points are located at the intersection of the horizontal hoop 3 and the vertical support 1.

[0049] In the sixth step, the device with the sonic logging tubes 2 tied is hoisted into the bored pile by a truck crane. During the hoisting process, due to the lever principle of the anchor rod 9, the anchor rod 9 will remain obliquely extended outwards. Under the support of the lower support rod 7, the upper hinge 6 and the lower hinge 8 will not overlap and close; when hoisted into the bored pile, the anchor rod 9 collides with the pile wall of the bored pile. Under the rotation of the lower hinge 8, it is ensured that there is no friction between the anchor rod 9 and the hole wall.

[0050] In the seventh step, during the pouring of the plain concrete pile, the above device floats under the action of buoyancy. Due to the support of the lower support rod 7, the anchor rod 9 will be inserted into the soil of the hole wall, preventing the sonic logging tube 2 from floating.

[0051] The above specific implementation manners have further elaborated on the purpose, technical solutions and beneficial effects of the present utility model. It should be understood that the above is only the specific implementation manners of the present utility model and is not used to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
