Description

Technical Field

[0001] The present invention relates to the technical field of pile foundation detection, and in particular to a construction foundation detection device and method based on load measurement. Background Art

[0002] Pile foundation dynamic testing is a testing and analysis instrument that detects the structural integrity of the engineering foundation pile and the vertical bearing capacity of a single pile under impact or vibration loads. The usual pile quality integrity test adopts a low-strain detection method, using one channel, a single probe, and a single hammer to collect a signal curve. Among them, the foundation detection device can be said to be an important detection device using this detection method.

[0003] Existing pile foundation detection devices mostly use a two-person operation method to detect the pile foundation, in which one person presses a probe on the pile head and strikes the pile top with a hammer to generate stress waves, while the other person preliminarily determines whether the curve is qualified based on the display of the pile tester connected to the probe and records it. However, the two-person operation method not only requires tacit cooperation between the two people, but also relies heavily on the operator's own work experience to work, which will affect the ease of use of the entire construction foundation detection device to a certain extent.

[0016] A detection method for a building construction foundation detection device based on load measurement, using a building construction foundation detection device based on load measurement as described above, includes the following steps:

[0017] S1: Move this device to the top of the foundation pile, and act on two fixed air pipes through a vacuum generator to suck the air inside the air collection cavity through the fixed air pipes, so as to adsorb the semi-empty column on both sides of the top of the foundation pile through the vacuum suction cup. Drive the meshing wheel to rotate through the first motor, so as to drive two meshing racks to move towards each other horizontally through the rotating meshing wheel, so that the connecting sleeve connected to the meshing rack can drive the connecting plate to move;

[0018] S2: Under the action of the moving connecting plate, the rotating wheel will be driven to rotate. During the movement, the uneven ground will force the leaning frame to move in the vertical direction, causing the limiting rod to move towards or away from the limiting hole, and drive a plurality of spacer bars to make a circular motion around the central axis of the rotating wheel through the rotating rotating wheel, so that the two leaning frames can clamp on both sides of the top of the foundation pile.

[0020] Advantages of the present invention:

[0021] 1. On the basis of the conventional foundation detection device, the detection device is improved. The cleaning component is driven to move through the adjustment component, so that the accelerometer on the cleaning component can be pressed against the top of the pile foundation. At the same time, the hydraulic push rod connected to the cleaning component is driven to move the knocking block, so that the knocking block can apply an instantaneous impact on the top of the pile to complete the vibration of the top of the pile. Then, the mechanical signal generated by the vibration of the pile body is obtained through the accelerometer and converted into an electrical signal. At the same time, the electrical signal is transmitted to the data acquisition instrument through the connecting wire to realize the single-person detection of the pile foundation.

[0022] 2. The two fixed air pipes are acted on by the vacuum generator, so that when the device is fixed, the air inside the air collection cavity can be pumped out, thus acting on the vacuum suction cup, so that the vacuum suction cup can strengthen the connection stability of the connecting piece to the ground. At the same time, the pumped-out air will be output through the air outlet pipe, so that the air discharged from the air outlet pipe can clean the surface of the pile foundation, and the phenomenon that dust blocks the accelerometer when the accelerometer is driven to move by the lead screw slide rail and the lead screw slider can be avoided. Furthermore, the working efficiency of the entire building construction foundation detection device can be greatly improved. Description of the drawings

The driving component 1 is used to drive the two connecting components 3 to move towards each other in the horizontal direction. The moving component 4 is used to drive the connecting component 3 to move along the bracket component 2. The adjustment component 6 is used to drive the dust cleaning component 7 to move in the vertical direction;

[0037] The detection component 5 includes a data collector 501 connected to the driving component 1, a connecting wire 502 connected to the data collector 501, an accelerometer 504 connected to the connecting wire 502, and a wire fixing clip 503 movably connected to the connecting wire 502. The data collector 501 is used to acquire the mechanical signals generated by the vibration or impact of the pile body and convert them into electrical signals. The accelerometer 504 is used to acquire the electrical signals transmitted by the data collector 501, perform amplification, filtering, and analog-to-digital conversion, and simultaneously display the waveform in real time, and adjust the sampling rate and gain;

[0038] The dust cleaning component 7 includes a flange cover 701 connected to the accelerometer 504, a combined plate 702 connected to the flange cover 701, a hydraulic push rod 703 connected to the combined plate 702, and a knocking block 704 connected to the hydraulic push rod 703. The hydraulic push rod 703 is used to drive the knocking block 704 to generate an instantaneous impact in the vertical direction to excite the vibration of the pile top.

[0039] According to Figure 2 、 Figure 6 And Figure 8 As shown, the bracket component 2 includes a slide rail frame 201 movably connected to the connecting component (3), a connecting head 202 connected to the slide rail frame 201, a semi-empty column 203 connected to the connecting head 202, an air collecting cavity 204 opened inside the semi-empty column 203, a connecting piece 205 connected to the semi-empty column 203, a vacuum suction cup 206 connected to the connecting piece 205, a filtering plate 211 connected to the inner wall of the semi-empty column 203, and a suction component connected to the semi-empty column 203. The vacuum suction cup 206 is used to adsorb the semi-empty column 203 to the ground surface. The filtering plate 211 is used to prevent the stone particles entering from the connecting piece 205 from being introduced into the suction component by negative pressure.

[0040] It should be noted that by setting the semi-empty column 203, the two ends of the detection device are positioned and fixed, and by setting the vacuum suction cup 206, the stability of the connection between the semi-empty column 203 and the ground is improved. At the same time, the filter plate 211 can be used to block the stone particles entering the inside of the air collection cavity 204, thereby further improving the connection stability of the vacuum suction cup 206.

[0041] According to Figures 7-8 and Figure 11 As shown, the suction assembly includes a fixed air pipe 207 connected to the semi-empty column 203, a multi-way head 208 connected to the fixed air pipe 207, an intake air pipe 209 connected to the multi-way head 208, a vacuum generator 210 connected to the intake air pipe 209, and an outlet air pipe 212 connected to the vacuum generator 210. The fixed air pipe 207 and the vacuum suction cup 206 are connected and communicated through the air collection cavity 204.

[0042] According to Figure 1 As shown, the driving assembly 1 includes a fixed sleeve 101 connected to the detection assembly 5, a connecting column 102 connected to the fixed sleeve 101, a baffle 103 connected to the connecting column 102, a camera 104 connected to the baffle 103, and a rotating assembly connected to the fixed sleeve 101. The camera 104 is used to obtain the video data of the data collector 501.

[0043] It should be noted that by setting the baffle 103, the top of the data collector 501 is blocked, thereby improving the viewing experience of the data collector 501. At the same time, by setting the camera 104, the data collector 501 can be recorded, so that the detection device can also leave a record of the work process when working alone, so as to reduce the misleading phenomenon in subsequent work.

[0044] According to Figures 5-6 As shown, the rotating assembly includes a first motor 105 connected to the fixed sleeve 101, a meshing runner 106 connected to the output shaft of the first motor 105, and soft cushion strips 107 connected to both side surfaces of the fixed sleeve 101. The first motor 105 is used to drive the two connecting assemblies 3 to move towards each other in the horizontal direction.

[0045] It should be noted that the first motor 105 is used to drive the meshing runner 106 to rotate, so as to synchronously drive the two meshing racks 302 to move towards each other through the rotating meshing runner 106, and the moving assembly 4 connected to the connecting assembly 3 can also move synchronously, thereby realizing the clamping of both ends of the pile top of the foundation pile. At the same time, by setting the soft cushion strips 107, the phenomenon that the moving assembly 4 hits the fixed sleeve 101 when moving and contracting can be prevented.

[0046] According to Figure 3As shown, the connecting component 3 includes meshing racks 302 respectively arranged at the front and rear ends of the meshing runner 106, a connecting sleeve 301 connected to the meshing rack 302, a fixing rod 303 connected to the connecting sleeve 301, a connecting plate 304 connected to the fixing rod 303, a fixed grip 305 connected to the connecting plate 304, a pulley sleeve 306 connected to the fixing rod 303, and an auxiliary pulley 307 movably connected to the pulley sleeve 306. The meshing rack 302 meshes with the meshing runner 106, and the slide rail frame 201 is movably connected to the auxiliary pulley 307.

[0047] It should be noted that through the setting of the auxiliary pulley 307, during the movement of the meshing rack 302, the movement of the auxiliary pulley 307 in the slide rail frame 201 can be driven to ensure the stability of the moving component 4 during movement. At the same time, through the setting of the fixed grip 305, the convenience of the user moving the connecting plate 304 by himself can be improved.

[0048] According to Figure 4 As shown, the moving component 4 includes a fixing strip 401 connected to the connecting plate 304, a limiting rod 404 connected to the fixing strip 401, and a moving seat component movably connected to the fixing strip 401.

[0049] According to Figure 4 As shown, the moving seat component includes a leaning frame 402 movably connected to the fixing strip 401, a fixed stop piece 403 connected to the leaning frame 402, a limiting hole 405 opened on the leaning frame 402, a return spring 406 connected to the leaning frame 402, a fixed pressing piece 407 connected to the return spring 406, a connecting wheel piece 408 connected to the leaning frame 402, a rotating wheel 409 movably connected to the connecting wheel piece 408, and a plurality of spacer bars 410 connected to the rotating wheel 409. The limiting hole 405 and the limiting rod 404 are set in one-to-one correspondence.

[0050] It should be noted that the position adjustment of the fixing strip 401 inside the leaning frame 402 is realized through the one-to-one corresponding limiting hole 405 and limiting rod 404, so that the rotating wheel 409 can adapt to the uneven ground. At the same time, through the setting of the return spring 406 and the fixed pressing piece 407, during the movement of the leaning frame 402, the phenomenon that the leaning frame 402 moves excessively and is difficult to rebound will not occur. At the same time, through the plurality of spacer bars 410 arranged on the rotating wheel 409, during the movement of the rotating wheel 409, the problem that the rotation of the rotating wheel 409 is blocked by stones can be avoided through the gaps between adjacent spacer bars 410, and thus the moving stability of the entire moving component 4 can be greatly improved.

[0051] According to Figure 10As shown in the figure, the adjusting assembly 6 includes a fixing piece 605 connected to the flange cover 701, a connecting block frame 604 connected to the fixing piece 605, screw rod sliders 603 respectively connected to both sides of the connecting block frame 604, a screw rod slide rail 602 movably connected to the screw rod sliders 603, and a mounting piece 601 connected to the screw rod slide rail 602. The mounting piece 601 is connected to the fixing sleeve 101. The screw rod sliders 603 and the screw rod slide rail 602 are used to drive the flange cover 701 to move along the air outlet pipe 212.

[0052] It should be noted that the screw rod slider 603 and the screw rod slide rail 602 cooperate with each other to drive the connecting block frame 604 to move, so as to drive the flange cover 701 to move synchronously through the connecting block frame 604, and make the moving flange cover 701 move the accelerometer 504, so that the detection device can be adapted to be operated by a single person, and thus the use convenience of the entire detection device can be greatly improved.

[0053] It should be noted that the detection method of the above-mentioned building construction foundation detection device based on load measurement includes the following steps:

[0054] S1: Move this device to the top of the foundation pile, and act on the two fixed air pipes 207 through the vacuum generator 210, so as to suck the air inside the air collection cavity 204 through the fixed air pipes 207, and use the vacuum suction cup 206 to adsorb the semi-empty column 203 on both sides of the top of the foundation pile. Drive the meshing runner 106 to rotate through the first motor 105, so as to drive the two meshing racks 302 to move in opposite directions horizontally through the rotating meshing runner 106, so that the connecting sleeve 301 connected to the meshing rack 302 can drive the connecting plate 304 to move;

[0055] S2: Under the action of the moving connecting plate 304, the rotating wheel 409 will be driven to rotate. During the moving process, the uneven ground will force the abutting frame 402 to move in the vertical direction, so that the limiting rod 404 moves towards or away from the limiting hole 405, and drive several spacer bars 410 to move in a circular motion around the central axis of the rotating wheel 409 through the rotating rotating wheel 409, so that the two abutting frames 402 can clamp on both sides of the top of the foundation pile. Then, drive the flange cover 701 to move through the screw rod slide rail 602 and the screw rod slider 603, so that the accelerometer 504 on the flange cover 701 can be pressed on the top of the foundation pile. At the same time, during the movement of the flange cover 701, the air inside the air collection cavity 204 sucked by the vacuum generator 210 can be ejected through the air outlet pipe 212 to realize dust cleaning at the position of the accelerometer 504;

[0056] S3: When the accelerometer 504 presses on the top of the base pile, the hydraulic push rod 703 is used to drive the percussion block 704 to move, so as to apply an instantaneous impact on the top of the base pile through the percussion block 704 to excite the vibration of the pile top, and the accelerometer 504 is used to collect the vibration generated by the pile body, convert it into an electrical signal, and transmit the electrical signal to the data collector 501 through the connection line 502, so that the data collector 501 amplifies, filters and performs analog-to-digital conversion on the electrical signal, and displays the waveform in real time, adjusts the sampling rate and gain. At the same time, the camera 104 located at the top of the data collector 501 is used to photograph and record the display data of the data collector 501, so as to realize the dynamic measurement and inspection of the base pile.

[0057] The whole process can be optimized from the two-person operation mode of having one person press the probe on the pile head and hold a force hammer to strike the pile top to generate stress waves, and the other person preliminarily judge whether the curve is qualified through the display of the pile tester connected to the probe and record it, to the single-person operation, so as to improve the convenience of using the whole device to a certain extent. And the adjustment component 6 is used to drive the dust cleaning component 7 to move, so that the dust cleaning component 7 can synchronously remove the dust on the pile top during the pressing process, and convert the generated dust during the cleaning process into the negative pressure for the device to adsorb to the ground, thereby improving the working efficiency of the whole device to a certain extent.

8. A detection method for a building construction foundation detection device based on load measurement, characterized in that: Adopt a building construction foundation detection device based on load measurement as described in claim 7, including the following steps: S1: Move this device to the top of the foundation pile, and act on two fixed air pipes (207) through a vacuum generator (210) to suck the air inside the air collection chamber (204) through the fixed air pipes (207), so as to adsorb the semi-empty column (203) on both sides of the top of the foundation pile through the vacuum suction cup (206). Drive the meshing wheel (106) to rotate through the first motor (105), so as to drive two meshing racks (302) to move towards each other horizontally through the rotating meshing wheel (106), so that the connecting sleeve (301) connected to the meshing rack (302) can drive the connecting plate (304) to move; S2: Under the action of the moving connecting plate (304), the rotating wheel (409) will be driven to rotate. During the moving process, the uneven ground will force the abutting frame (402) to move in the vertical direction, so that the limiting rod (404) moves towards or away from the limiting hole (405), and drive a number of spacer bars (410) to move in a circular motion around the central axis of the rotating wheel (409) through the rotating rotating wheel (409), so that two abutting frames (402) can be clamped on both sides of the top of the foundation pile. Then drive the flange cover (701) to move through the lead screw slide rail (602) and the lead screw slider (603), so that the accelerometer (504) on the flange cover (701) can press on the top of the foundation pile. At the same time, during the movement of the flange cover (701), the air inside the air collection chamber (204) sucked by the vacuum generator (210) can be ejected through the air outlet pipe (212) to realize dust cleaning at the accelerometer (504); S3: When the accelerometer (504) presses on the top of the foundation pile, drive the knocking block (704) to move through the hydraulic push rod (703), so as to apply an instantaneous impact on the top of the foundation pile through the knocking block (704) to stimulate the vibration of the top of the pile, and collect the vibration generated by the pile body through the accelerometer (504) and convert it into an electrical signal. Transmit the electrical signal to the data acquisition instrument (501) through the connecting wire (502), so as to amplify, filter and perform analog-to-digital conversion on the electrical signal by the data acquisition instrument (501), and display the waveform in real time, adjust the sampling rate and gain. At the same time, take a picture and record the display data of the data acquisition instrument (501) through the camera (104) located at the top of the data acquisition instrument (501) to realize the dynamic measurement and inspection of the foundation pile.
