Description

Technical Field

[0001] The invention relates to the technical field of construction engineering, in particular to a method and equipment for detecting foundation piles of construction engineering. Background Art

[0002] The foundation pile is a single pile in the foundation pile, a load-bearing rod buried vertically or slightly inclined in the soil. It is the basic component unit of the pile foundation. The foundation pile usually consists of two parts: the pile body and the pile cap. The pile body is buried in the soil, while the pile cap is used to connect the superstructure to jointly bear and transfer the load.

[0003] Pile testing refers to the testing of the bearing capacity of a single pile and the integrity of the pile body. It is a key step to ensure that the quality of the pile meets the design requirements and safety standards. Through testing, we can understand the bearing capacity of a single pile under different loads and ensure that the pile can withstand the load from the superstructure. We can also test whether there are defects or damages in the pile body, such as cracks and voids, to evaluate the integrity and durability of the pile body. The acoustic wave transmission method is suitable for concrete cast-in-place piles with pre-buried acoustic detection tubes. The propagation speed and attenuation of acoustic waves in the pile body can be used to evaluate the integrity and quality of the pile body concrete.

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] Embodiment 1:

[0039] like Figure 1 - Figure 5As shown, a construction engineering pile detection device of the present invention is a pile detection assembly 1 for detecting construction piles, comprising a support plate 11; a corresponding support hole 111 is opened on the side wall of the support plate 11, and a group of support plates 11 are supported and connected by a side support plate 16; an acoustic wave monitor 12 is arranged in the middle of the side wall of one of the support plates, and an acoustic wave recorder 13 is arranged on the side wall of the other side support plate;

[0040] A pushing assembly for moving along the outer wall of the foundation pile is provided at the bottom of the support plate 11, and the pushing assembly includes an upper pushing member 2 and a lower pushing member 3, wherein one of the support plates 11 is fixedly connected to the middle of the upper surface of the upper pushing member 2, and a clamping assembly 6 is provided on the same side of the upper pushing member 2 and the lower pushing member 3, and the lower pushing member 3 is fixed to the outer wall of the foundation pile by the clamping assembly 6, and the upper pushing member 2 moves to push the acoustic wave monitor 12 and the acoustic wave recorder 13 to the detection position.

[0041] The pile body quality can be detected by using the propagation characteristics of ultrasound in concrete through the setting of the pile foundation detection component 1. Several acoustic detection tubes are pre-buried in the pile as channels for ultrasonic receiving and transmitting transducers. During detection, a transmitting probe for transmitting ultrasound is placed in one tube, and a receiving probe for receiving ultrasound is placed in another tube. The two probes are lifted up synchronously from the bottom, and the acoustic characteristics of the pile foundation detection component 1 propagating in the concrete side composed of the two tubes. According to the arrival time, amplitude, frequency change and waveform distortion of the wave, after analysis and processing, the quality status of the concrete can be determined, including the nature, size and spatial position of the defects, the homogeneity of the concrete, etc.

[0042] By setting the sound wave monitor 12 and the sound wave recorder 13, it is possible to monitor the sound waves at different heights and record the sound wave information, which is beneficial for the staff to analyze the data. By setting the upper pusher 2, the pile detection assembly 1 can be pushed to a preset position. When the upper pusher 2 is fixed to the pile through the clamping assembly 6, the lower pusher 3 moves upward along the pile foundation. After the lower pusher 3 is clamped and fixed to the pile foundation through the clamping assembly 6, the upper pusher 2 uses the lower pusher 3 as support to drive the sound wave monitor 12 and the sound wave recorder 13 to move upward, and brings the sound wave monitor 12 and the sound wave recorder 13 to the preset position, which is convenient for detecting the pile foundation bearing the superstructure at different heights.

[0043] The two support plates 11 can be supported by the side support plates 16 , and the positions of the two side support plates 16 can be adjusted through the support holes 111 . The staff can adjust the positions of the two side support plates 16 according to the diameter of the foundation piles.

[0044] Specifically, a circuit box 14 is fixedly connected to the middle of the support plate 11, the sound wave monitor 12 and the sound wave recorder 13 are connected to the corresponding circuit boxes 14, a plurality of limiting holes 18 are opened on the side wall of the side support plate 16, a limiting clamping ring 17 is sleeved on the outer wall of the side support plate 16, and a blocking bolt 19 for blocking the limiting clamping ring 17 is arranged in the limiting hole 18.

[0045] The support plate 11 can be blocked by the blocking bolts 19 to prevent the acoustic wave monitor 12 and the acoustic wave recorder 13 from loosening. The position of the acoustic wave monitor 12 and the acoustic wave recorder 13 can be adjusted by the setting of the limiting holes 18 so that they can be at a suitable distance from the outer wall of the superstructure supported by the foundation piles. The setting of the circuit box 14 can provide guarantee for the normal operation of the acoustic wave monitor 12 and the acoustic wave recorder 13.

[0046] Specifically, the upper pusher 2 includes an installation box 21, a driving motor 22 is fixedly connected inside the installation box 21, a driving gear 23 is fixedly connected to the output end of the driving motor 22, a rotating main shaft 24 is rotatably arranged in the middle of the installation box 21, a driven gear 25 is fixedly connected to the outside of the rotating main shaft 24, and the driven gear 25 is meshed with the driving gear 23.

[0047] A first lever arm 26 is fixedly sleeved at the end of the rotating main shaft 24. The internal structure of the lower push member 3 is the same as that of the upper push member 2, and second lever arms 31 are arranged on both sides of the lower push member 3. The second lever arm 31 is connected to the first lever arm 26 through the pushing shaft 4, and the second lever arm 31 and the first lever arm 26 are both rotatably connected to the outer wall of the pushing shaft 4.

[0048] The installation box 21 plays a supporting and installation role, and plays a protective role for the internal components. The driving motor 22 is turned on, and the output end of the driving motor 22 drives the driving gear 23 to rotate. The driving gear 23 drives the driven gear 25 to rotate synchronously during the rotation process. During the rotation process of the driven gear 25, the connected rotating main shaft 24 can be driven to rotate. During the rotation process of the rotating main shaft 24, the first force arm 26 can be driven to rotate. At this time, during the upward movement of the first force arm 26, the lower pusher 3 is pulled upward through the second force arm 31;

[0049] The first force arm 26 and the second force arm 31 will rotate with the outer wall of the driving shaft 4, and the driving shaft 4 plays a connecting role.

[0050] Specifically, a stabilizing rod 5 is fixedly connected and penetrated in the installation box 21 , the lower end of the stabilizing rod 5 extends into the lower pushing member 3 , and the stabilizing rod 5 is slidably connected to the lower pushing member 3 .

[0051] When the lower push member 3 moves upward, the stabilizing rod 5 plays a guiding role. At this time, the installation box 21 is in a fixed state. The lower push member 3 moves upward along the stabilizing rod 5, so that the lower push member 3 can move in the vertical direction, ensuring that the clamping assembly 6 can clamp to the outer wall of the foundation pile, and the lower push member 3 will not move to the side away from the foundation pile and become unable to clamp.

[0052] Embodiment 2:

[0053] It is basically the same as the first embodiment. Figure 1 , Figure 3 , Figure 5-7 As shown, the difference is that a group of electric control push rods 62 are fixedly connected inside the installation box 21, the electric control push rods 62 are symmetrically arranged, and the telescopic ends of the electric control push rods 62 are fixedly connected with sliding force arms 63.

[0054] After the upper push member 2 is clamped stably, the rotation of the sliding force arm 63 can drive the lower push member 3 to move upward, thereby driving the corresponding clamping assembly 6 to move upward. The telescopic end of the electric control push rod 62 can be extended to clamp the pile. The telescopic end of the electric control push rod 62 is shortened to separate it from the pile, and the lower push member 3 can move freely.

[0055] Specifically, one end of the sliding force arm 63 away from the electric control push rod 62 is rotatably connected to the force arm rod 64, and the sliding force arm 63 and the force arm rod 64 are rotatably connected through the first pin rod 631. The clamping assembly 6 includes a clamping force arm 65, and the clamping force arm 65 and the force arm rod 64 are connected through the second connecting pin 651;

[0056] A supporting shaft is fixedly connected to the middle part of the clamping arm 65, and the supporting shaft is rotatably connected to the groove set in the installation box 21. An arc-shaped clamping plate 66 is fixedly connected to the end of the clamping arm 65 away from the installation box 21. The arc-shaped clamping plate 66 is arranged in an arc shape, and an inner clamping arc plate 67 is arranged on the inner side of the arc of the arc-shaped clamping plate 66. An anti-slip clamping layer 68 is fixedly connected to the inner side of the inner clamping arc plate 67.

[0057] During the extension of the telescopic end of the electric control push rod 62, the sliding lever arm 63 will be pushed to slide along the inner wall of the installation box 21. During the process of the sliding lever arm 63 pushing the lever arm rod 64, the lever arm rod 64 will rotate relative to the sliding lever arm 63 along the first pin rod 631. Under the push of the lever arm rod 64, the clamping lever arm 65 starts to rotate, and the end of the same group of clamping lever arms 65 away from the lever arm rod 64 moves toward the side close to each other. The clamping lever arms 65 rotate along the supporting shaft, and the arc clamping plate 66 moves toward the upper structure supported by the foundation pile, while driving the inner clamping arc plate 67 to move synchronously, and the stability of the clamping is achieved by the anti-slip clamping layer 68 fitting with the outer wall of the upper structure supported by the foundation pile.

[0058] Specifically, the side of the arc-shaped clamping plate 66 away from the inner clamping arc-shaped plate 67 is fixedly connected to the outer support frame 69, and a mounting hole 691 is opened on the lower surface of the outer support frame 69. The side of the inner clamping arc-shaped plate 67 close to the arc-shaped clamping plate 66 is fixedly connected to a connecting shaft 694, and the connecting shaft 694 rotates and penetrates the arc-shaped clamping plate 66, and the connecting shaft 694 extends to the middle of the outer support frame 69. One end of the connecting shaft 694 placed on the outer support frame 69 is fixedly connected to a counterweight block 692, and both sides of the counterweight block 692 are fixedly connected to a return spring 693, and the end of the return spring 693 away from the counterweight block 692 is fixedly connected to the inner wall of the mounting hole 691;

[0059] A friction support sheet 661 is fixedly connected to one side of the arc-shaped clamping plate 66 close to the inner arc-shaped clamping plate 67 , and the friction support sheet 661 is in contact with the inner arc-shaped clamping plate 67 .

[0060] The setting of the counterweight block 692 can ensure that the inner clamping arc plate 67 can be in a horizontal state when clamping, and ensure that the inner clamping arc plate 67 can better fit with the outer wall of the upper structure supported by the foundation pile during clamping, so as to avoid the inner clamping arc plate 67 from tilting and causing the purpose of firm clamping. The setting of the reset spring 693 can reduce the excessive shaking amplitude of the counterweight block 692 during the movement of the outer support frame 69, which affects the clamping action. The setting of the counterweight block 692 can make the inner clamping arc plate 67 rotate with the arc clamping plate 66 at a certain angle in the non-clamping state, ensuring that the inner clamping arc plate 67 is always in a horizontal state, which is conducive to the clamping of the outer wall of the upper structure supported by the foundation pile. During the clamping process, the friction support sheet 661 will press against the inner clamping arc plate 67 to ensure the overall stability after clamping.

[0061] Working principle: When it is necessary to move the acoustic wave monitor 12 and the acoustic wave recorder 13 to the top position of the foundation pile supporting the superstructure, the acoustic wave monitor 12 and the acoustic wave recorder 13 are placed outside the foundation pile, and then the acoustic wave monitor 12 and the acoustic wave recorder 13 are connected together through the side support plate 16, and several acoustic detection tubes are pre-buried in the pile to emit ultrasonic waves.

[0062] The driving motor 22 is turned on, and the output end of the driving motor 22 drives the driving gear 23 to rotate, and the driving gear 23 drives the driven gear 25 to rotate synchronously during the rotation process. During the rotation process of the driven gear 25, the connected rotating main shaft 24 can be driven to rotate, and during the rotation process of the rotating main shaft 24, the first lever arm 26 can be driven to rotate. At this time, during the upward movement of the first lever arm 26, the lower pusher 3 is pulled upward by the second lever arm 31. During the upward movement of the lower pusher 3, the stabilizing bar 5 plays a guiding role. After the lower pusher 3 is clamped with the outer wall of the upper structure supported by the foundation pile, the clamping assembly 6 on one side of the installation box 21 is released, and the installation box 21 is pushed upward with the lower pusher 3 as the fulcrum, and the top-connected acoustic wave monitor 12 and acoustic wave recorder 13 are driven to move at the same time, and the acoustic wave monitor 12 and acoustic wave recorder 13 are transported to the preset position and then stopped.

[0063] By setting up the sound wave monitor 12 and the sound wave recorder 13, sound waves at different heights can be monitored and the sound wave information can be recorded, which is beneficial for the staff to analyze the data.

[0064] A construction engineering pile detection method comprises the following steps: S1: using a flat measurement method to conduct a census of all detection sections of the entire pile to find out the measurement points with abnormal acoustic parameters;

[0065] S2: The transmitting and receiving sound wave transducers always maintain the same depth for sound wave transmission;

[0066] S3: For measurement points with abnormal acoustic parameters, use intensified testing, oblique testing or sector scanning;

[0067] S4: The transmitting and receiving sound wave transducers always maintain a fixed height difference.

[0068] After the upper push member 2 is clamped stably, the rotation of the sliding force arm 63 can drive the lower push member 3 to move upward, thereby driving the corresponding clamping assembly 6 to move upward. The foundation pile can be clamped during the extension of the telescopic end of the electric control push rod 62. The telescopic end of the electric control push rod 62 is shortened to separate it from the foundation pile, and the lower push member 3 can move freely. During the extension of the telescopic end of the electric control push rod 62, the sliding force arm 63 is pushed to slide along the inner wall of the installation box 21. The sliding force arm 63 pushes the force arm rod 6 4, the lever arm 64 will rotate relative to the sliding lever arm 63 along the first pin 631. Under the push of the lever arm 64, the clamping lever arm 65 starts to rotate, and the end of the same group of clamping lever arms 65 away from the lever arm 64 moves toward the side close to each other. The clamping lever arms 65 rotate along the supporting shaft, and the arc clamping plate 66 moves toward the upper structure supported by the pile foundation, while driving the inner clamping arc plate 67 to move synchronously, and the stability of the clamping is achieved by the anti-slip clamping layer 68 being fitted with the outer wall of the upper structure supported by the pile foundation.
