For the curtain wall pile foundation detection equipment of the present invention, before detecting the pile foundation to be tested, if the position of the laser alignment device is shifted due to reasons such as ground inclination, horizontal adjustment is required. In this case, the liquid levels of the driving liquid in the socket pipes of the four radial pipes on the other vertical section of the leveling structure will tend to be at the same height.

[0034] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention and are not intended to limit the invention. In addition, it should be noted that for the sake of description, only the parts related to the invention are shown in the drawings.

[0035] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0036] Refer to Figures 1 to 7 As shown, the present invention provides a curtain wall pile foundation detection device, including: a moving base 1, a leveling structure 2, a laser straightness measuring device 3, and an ultrasonic detection device 4.

[0037] In this embodiment, the moving base is generally rectangular. Rollers are respectively installed at the four corners of the moving base. The moving base 1 has a front end and a rear end that are opposite to each other. The front and rear ends of the moving base 1 are in the front and rear directions based on the traveling direction of the moving base. The front end of the moving base 1 is at the front end in the traveling direction of the moving base 1, and the rear end of the moving base 1 is at the rear end in the traveling direction of the moving base 1.

[0038] A support plate 11 is vertically provided at the rear end of the moving base 1. A receiving socket is formed at the top of the support plate 11. A first chute a is provided on the outer side of the support plate 11 away from the front end of the moving base 1 and is arranged in the vertical direction. The bottom of the first chute a communicates with the receiving socket. A driving rod 12 is adjustably installed in the receiving socket. The bottom end of the driving rod 12 is connected to an inclined support rod 13.

[0039] In this embodiment, the receiving socket is a threaded hole, and the driving rod is formed with an external thread. The driving rod is screwed into the receiving socket. When locking the moving base, the driving rod is rotated to insert the insert into the foundation.

[0040] The inclined support rod 13 slides in the first chute a. The lower end of the inclined support rod 13 is inclined downward and outward and is connected to an insert 14. The insert 14 is used for anchoring in the foundation.

[0041] After the moving base moves into place, adjust the position of the driving rod in the receiving socket so that the inclined support rod descends, and then the insert 14 is anchored in the foundation to lock the moving base. When it is necessary to move the moving base, reverse the position of the driving rod so that the insert is separated from the foundation.

[0042] The leveling structure 2 is used to adjust the levelness of several straightness measuring devices. Specifically, the leveling structure 2 includes a liquid storage tube 21, a vertical section 22, a bearing tray 23, a radial tube 24, a receiving and inserting tube 25, a plugging block 26, and a piston block 28.

[0043] Among them, the liquid storage pipe 21 is used to accommodate the driving liquid. In some embodiments, the driving liquid is water. Preferably, the driving liquid is antifreeze. The liquid storage pipe is arranged along the plate surface direction of the moving base. In this embodiment, the liquid storage pipe is arranged along the length direction of the moving base. The liquid storage pipe 21 is fixedly arranged at the front end of the moving base 1.

[0044] Refer to Figure 4 and Figure 5 As shown, vertical sections 22 are respectively formed by upward extension at both ends of the liquid storage pipe 21. A piston block 28 is slidably arranged at the port of one vertical section 22 (the vertical section close to the support plate). A four-radial pipe 24 is connected to the port of the other vertical section 22 (the vertical section far from the support plate). The four-radial pipes 24 are arranged at equal intervals along the circumferential direction of the other vertical section 22. Each radial pipe is arranged along the radial direction of the vertical section. The end of the radial pipe 24 far from the other vertical section 22 extends upward to form a socket pipe 25.

[0045] Four insertion blocks 26 are formed at the bottom of the support tray 23. The four insertion blocks 26 are arranged at equal intervals along the circumferential direction of the support tray 23. The insertion block 26 is movably inserted into the socket pipe 25.

[0046] In this embodiment, the liquid storage pipe 21 is filled with the driving liquid. At least the lower section of the vertical section is also filled with the driving liquid. A sealed air cavity is formed between the liquid level of the driving liquid in one vertical section and the piston block. When the foundation is inclined, the piston block 28 is pressed downward to make the driving liquid in the liquid storage pipe 21 flow into or be pressed into the four-radial pipes 24 and the four socket pipes 25. Since the liquid levels of the driving liquid in the four socket pipes are always horizontal, the driving liquid in the four socket pipes 25 supports the four insertion blocks 26 to make the support tray 23 arranged in the horizontal direction.

[0047] The laser alignment device 3 is a laser. The laser emits a vertical laser beam. The laser alignment device 3 is connected with a telescopic rod 31. The length of the telescopic rod 31 is adjustable. The telescopic rod 31 is arranged along the radial direction of the support tray 23. The end of the telescopic rod 31 far from the laser alignment device 3 is rotatably installed on the support tray 23 through a hinge shaft. The hinge shaft is arranged along the central axis of the support tray.

[0048] The ultrasonic detection device 4 is installed at the bottom of the moving base 1. In this embodiment, the ultrasonic detection device 4 is a non-metallic ultrasonic detector.

[0049] The ultrasonic detection device is used to detect the inside of the pile foundation, detect and locate the concrete strength, internal defects of the concrete, and the depth of concrete cracks through the ultrasonic rebound comprehensive method, and determine the integrity of the pile foundation.

[0050] As a preferred implementation manner, refer to Figure 2As shown in the figure, a second chute b is formed inside the support plate 11 and is arranged vertically. A base 5 is slidably arranged in the second chute b. The base is plate-shaped. One end of the base is slidably arranged in the second chute. The other end of the base extends above the middle of the moving base.

[0051] The moving base 1 is provided with a vertical through hole. The vertical through hole is arranged directly below the other end of the base. A threaded sleeve 54 is installed at the upper port of the vertical through hole. The threaded sleeve 54 is arranged vertically. The threaded sleeve 54 is coaxially arranged with the vertical through hole. A driving motor 51 is installed on the base 5. The output shaft of the driving motor 51 is connected with a first screw rod 52. The first screw rod 52 is screwed into the threaded sleeve 54. The lower end of the first screw rod 52 is connected with a drill bit 53. The transmitting transducer 41 of the non-metallic ultrasonic detector is installed at the bottom of the moving base. The receiving transducer 42 of the non-metallic ultrasonic detector is installed on the drill bit 53.

[0052] Continue to refer to Figure 4 and Figure 5 As shown in the figure, the piston block 28 is connected with a push rod. One end of the push rod extends outside the port of the vertical section 22. A first flange for preventing the piston block 28 from slipping off is formed by the inward extension of the port of the vertical section 22. The first flange is arranged in a circle along the circumferential direction of the port of the vertical section.

[0053] Refer to Figure 2 、 Figure 4 、 Figure 5 As shown in the figure, the insertion block 26 is connected with a chassis. A second flange for preventing the chassis from slipping off is formed by the extension of the pipe orifice of the receiving pipe 25. The second flange is arranged in a circle along the circumferential direction of the pipe orifice of the receiving pipe.

[0054] As a preferred embodiment, a fine adjustment plate 27 is installed on the bearing tray 23 in a liftable manner. The telescopic rod 31 is installed on the fine adjustment plate 27 through a hinge shaft.

[0055] A plurality of screwed parts are rotatably installed on the bearing tray 23. A plurality of second screw rods 271 are formed at the bottom of the fine adjustment plate 27. The second screw rods 271 are screwed into the screwed parts.

[0056] A bubble level is installed on the bearing tray 23. When adjusting the levelness of the bearing tray through the leveling structure, when the bearing tray is level, the verticality of the pile foundation can be detected by the laser alignment device 3.

[0057] The present invention provides a curtain wall pile foundation detection method using a curtain wall pile foundation detection device, including the following steps:

[0058] S1. Move the moving base 1 to one side of the pile foundation to be detected.

[0059] S2. Adjust the position of the driving rod 12 in the receiving hole, and the inclined support rod 13 moves downward to anchor the insert piece 14 in the foundation.

[0060] Specifically, when locking the mobile base, the insertion piece is inserted into the foundation by rotating the driving rod.

[0061] S3. When the foundation is inclined, by pressing against the piston block 28 of the leveling structure 2, the driving liquid in the liquid storage pipe 21 floods into the four radial pipes 24 and the four socket pipes 25, so that the driving liquid in the four socket pipes 25 supports the four insertion blocks 26 to make the bearing tray 23 set horizontally.

[0062] S4. Adjust the length of the telescopic rod 31 so that the laser alignment device 3 abuts against one side of the pile foundation to be measured.

[0063] In this embodiment, the telescopic rod includes a horizontal sleeve and a core rod. The horizontal sleeve is arranged along the disk surface direction of the fine adjustment disk. One end of the horizontal sleeve is rotatably installed with a hinge shaft. The hinge shaft is fixed at the center of the fine adjustment disk. The fine adjustment disk and the bearing tray are coaxially arranged. One end of the core rod is inserted into the other end of the horizontal sleeve in a manner that can move along the length direction of the horizontal sleeve. The laser is installed on the other end of the core rod.

[0064] When adjusting the telescopic rod, the length of the telescopic rod is adjusted by adjusting the insertion depth of the core rod in the horizontal sleeve.

[0065] In some embodiments, the telescopic rod is an electric hydraulic push rod.

[0066] S5. Turn on the laser alignment device 3 to detect the verticality of the pile foundation to be measured.

[0067] S6. Move the mobile base 1 above the pile foundation to be measured, and use the ultrasonic detection device 4 to detect the concrete strength, internal defects of the concrete, and the depth of concrete cracks of the pile foundation to be measured to determine the integrity of the pile foundation to be measured.

[0068] After the mobile base moves above the pile foundation to be measured, the transmitting transducer 41 and the receiving transducer 42 are respectively arranged on opposite sides of the pile foundation to be measured. After the transmitting transducer 41 abuts against one side of the pile foundation to be measured, the mobile base is locked by the driving rod. Then, the first screw rod is rotated by the driving motor, so that the drill bit penetrates through the perforation of the mobile base and drills into the foundation, and further makes the receiving transducer 42 on the drill bit abut against the other side of the pile foundation to be measured.

[0069] During use, the transmitting transducer 41 and the receiving transducer 42 of the non-metallic ultrasonic detector are respectively placed on both sides of the pile foundation and aligned, and then the pile foundation is detected by analyzing the signal waveform and acoustic parameter data. The higher the alignment accuracy, the higher the accuracy of the pile foundation detection.

[0070] In some embodiments, refer to Figure 6 and Figure 7As shown, a vertical channel is provided inside the first screw rod and the drill bit. The upper end of the vertical channel is connected with an extrusion column. The extrusion column is connected with an elastic guiding rod. The receiving transducer is fixedly installed at the end of the elastic guiding rod. The transmitting transducer is fixedly installed below the moving base.

[0071] For the curtain wall pile foundation detection device of the present invention, before detecting the pile foundation to be measured, if the position of the laser straightness measuring device is shifted due to reasons such as ground inclination, horizontal adjustment is required. The liquid levels of the driving liquid in the socket pipes of the four radial pipes on the other vertical section of the leveling structure will tend to the same height, and the piston block pushes the driving liquid, so that the four plug-in blocks are located on the same horizontal plane, thus ensuring that the laser straightness measuring device is in a horizontal state. The present invention detects the vertical condition of the curtain wall pile foundation, thereby avoiding the inclination of the curtain wall pile foundation and ensuring the stability during subsequent use. When detecting, when it is necessary to fix the position of the moving base, the driving rod is used to drive the insert piece to insert into the foundation for position locking, avoiding the position movement of the moving base and affecting the detection result.

[0072] For the curtain wall pile foundation detection device of the present invention, the screw member on the fine adjustment disc is rotated to adjust the levelness of the fine adjustment disc, thereby ensuring the horizontal state of the laser straightness measuring device.

[0073] The curtain wall pile foundation detection device of the present invention moves the laser straightness measuring device to the vertical position of the curtain wall and the pile foundation, and detects the verticality of the curtain wall and the pile foundation through the laser, thereby avoiding the occurrence of inclination during the construction process.

[0074] The curtain wall pile foundation detection device of the present invention detects the inside of the pile foundation to be measured through the ultrasonic detection device, and detects and locates the concrete strength, internal defects of the concrete, and the depth of concrete cracks through the ultrasonic rebound comprehensive method, and determines the integrity of the pile foundation.

[0075] The above description is only the preferred embodiment of the present application and the explanation of the applied technical principle. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
