Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a non-destructive testing device for the quality of interlocking piles. Background Technology

[0002] Interlocking piles are constructed by partially interlocking circumferential sections of adjacent concrete piles, with reinforcing cages inserted into subsequent piles to form a continuous, waterproof, and retaining structure with excellent seepage prevention capabilities. To ensure the integrity of the completed pile foundation structure and achieve good waterproofing and seepage prevention, a pile quality inspection must be conducted after the interlocking piles are constructed. For pile foundations of Class I buildings and pile foundation projects with complex geological conditions or low reliability of borehole quality, pile integrity testing should be performed.

[0003] Due to the unique characteristics of the interlocking pile construction method, the low-strain dynamic testing method has significant limitations in detecting the integrity of plain concrete piles. This often leads to large deviations in measurement results or the inability to collect limited measurement data. Furthermore, the core sampling method damages the pile structure and may affect the overall structural safety of the interlocking pile. Therefore, a non-destructive testing installation tool is needed for effective detection. Utility Model Content

[0004] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a non-destructive testing device for the quality of interlocking piles, so as to solve the existing problems.

[0006] To achieve the above objectives, the technical solution of this utility model is: a non-destructive testing device for the quality of interlocking piles, comprising four steel pipes embedded around the interlocking pile and a support base. A placement platform is mounted on the top of the support base. A corresponding first motor is mounted on the placement platform relative to the steel pipes. Each output end of the first motor is equipped with a take-up roller, which collects the test line. The test line passes through the corresponding hole in the placement platform. One end of the test line is equipped with an ultrasonic testing probe, and the other end is connected to a corresponding detector to read the corresponding data.

[0007] In some embodiments, the placement platform is provided with a wire guide tube on top, and the side wall of the wire guide tube is provided with a wire guide groove, through which the detection wire passes.

[0008] In some embodiments, a limiting plate is provided between the ultrasonic testing probe and the testing line, and the limiting plate is set with a diameter proportional to that of the steel pipe opening.

[0009] In some embodiments, slide rails are provided on both sides of the bottom of the support base, a second motor is provided at one end of the slide rail, a threaded rod is provided in the slide rail to connect the second motor, and a sliding block is provided on the threaded rod to realize movement. The sliding block is connected to the bottom of the support base, and a support frame is provided at the bottom of the slide rail.

[0010] In some embodiments, the spool is equipped with a cylinder, the output end of which passes through the placement platform and is connected to the fixing plate.

[0011] In some embodiments, the support frame is provided with a sliding groove, the bottom of the sliding groove is provided with a connecting groove, a moving block is provided in the sliding groove, the bottom of the moving block is provided with a positioning rod, the bottom of the positioning rod is spike-shaped, and the outside of the support frame is provided with two fixing holes. The fixing rod is passed through the fixing holes to pass through the moving block for fixing, so as to prevent the moving block from moving.

[0012] By adopting the above technical solution, the beneficial effects of this utility model are as follows: This utility model sets up the support base above the steel pipe, and then controls the first motor to drive the take-up roller to rotate so that it slowly lowers the detection line, thereby lowering the ultrasonic detection probe to enter the steel pipe for acoustic detection. During the detection, the detection line feeds back to the detector to check whether the interlocking pile is broken. The interlocking pile needs to be tapped during the detection to achieve acoustic detection, so there is no need to drill the core to check the internal condition of the interlocking pile, thus achieving non-destructive testing.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0032] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0035] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0036] Reference Figure 1-2 This utility model provides a non-destructive testing device for the quality of interlocking piles, including four steel pipes 1 embedded around the interlocking pile 4 and a support base 2. A placement platform 21 is mounted on the top of the support base 2. A corresponding first motor 22 is provided on the placement platform 21 and the steel pipes 1. Each output end of the first motor 22 is equipped with a take-up roller 23, which takes in the test line 24. The test line 24 passes through the corresponding hole in the placement platform 21. One end of the test line 24 is equipped with an ultrasonic testing probe 25, and the other end is connected to a corresponding detector to read the corresponding data.

[0037] By mounting the support base 2 above the steel pipe 1, and then controlling the first motor 22 via a controller connected to it, the first motor 22 drives the take-up roller 23 to rotate, slowly lowering the detection line 24. This lowers the ultrasonic testing probe 25 into the steel pipe 1 for acoustic testing. During the test, the detection line 24 feeds back to the detector to check for any breakage in the interlocking post 4. The interlocking post 4 needs to be tapped during the test to achieve acoustic detection, thus eliminating the need for external core drilling to examine the internal condition of the interlocking post, achieving non-destructive testing. Furthermore, subsequent filling of the steel pipe 1 further increases the robustness of the interlocking post. Additionally, the detection line 24 passes through the holes in the placement platform 21 to prevent excessive shaking of the take-up roller 23 when lowering the detection line 24.

[0038] According to some embodiments of this utility model, optionally, the top of the placement platform 21 is provided with a wire guide tube 3, and the side wall of the wire guide tube 3 is provided with a wire guide groove 31, through which the detection wire 24 passes. This prevents the wire from becoming too messy.

[0039] According to some embodiments of this utility model, optionally, a limiting plate 26 is provided between the ultrasonic testing probe 25 and the testing line 24, and the limiting plate 26 is set with a diameter proportional to the opening of the steel pipe 1. This prevents the ultrasonic testing probe 25 from being repeatedly struck during descent, thus avoiding damage and inaccurate testing.

[0040] According to some embodiments of this utility model, optionally, the support base 2 is provided with slide rails 5 on both sides of its bottom. A second motor 51 is provided at one end of each slide rail 5, and a threaded rod is provided in the slide rail 5 to connect to the second motor 51. A sliding block 52 is then provided on the threaded rod to achieve movement. The sliding block 52 is connected to the bottom of the support base 2, and a support frame 53 is provided at the bottom of the slide rail 5. The slide rails 5 are placed on both sides of the interlocking piles 4, and then the support base 2 and the sliding block 52 are connected. In this way, the controller can connect to the second motor 51 to control the rotation of the threaded rods of the slide rails 5 on both sides, thereby moving the sliding block 52. This allows for testing of a row of interlocking piles 4 without having to move the entire device during testing.

[0041] According to some embodiments of this utility model, optionally, a cylinder 32 is provided inside the wire guide spool 3, and the output end of the cylinder 32 passes through the placement platform 21 and is connected to the fixing plate 33. When the ultrasonic testing probe 25 is placed, the cylinder 32 can be controlled by a controller connected to the cylinder 32 to lower the fixing plate 33, thereby increasing the stability of the placement platform 21 and preventing it from shaking during descent. At the same time, the cylinder 32 can also move the fixing plate 33 up and down to perform the sound wave test by tapping.

[0042] According to some embodiments of this utility model, optionally, the support frame 53 is provided with a sliding groove 54, the bottom of the sliding groove 54 is provided with a connecting groove 55, a moving block 56 is provided in the sliding groove 54, and a positioning rod 57 is provided at the bottom of the moving block 56. The bottom of the positioning rod 57 is spike-shaped. The outer side of the support frame 53 is provided with two fixing holes 58. The fixing rod is passed through the fixing holes 58 and then through the fixing holes 58 to fix the moving block 56, preventing the moving block 56 from moving. In actual situations, the positioning rod 57 can be released, and then the fixing rod can be passed through the fixing holes 58 to prevent the moving block 56 from moving, thus fixing it. In this way, the positioning rod 57 can be inserted into the soil for fixation in loose ground.
