Description

Technical Field

[0001] The invention belongs to the technical field of detection equipment, and particularly relates to a building foundation pile detection device and method. Background Art

[0002] Pile foundation: A foundation jointly composed of piles and a bearing platform connected to the top of the piles. If the entire pile body is buried in the soil and the bottom surface of the bearing platform contacts the soil mass, it is called a low-capacity pile foundation; if the upper part of the pile body is exposed above the ground and the bottom of the bearing platform is above the ground, it is called a high-capacity pile foundation. Building pile foundations are usually low-capacity pile foundations. Single-pile foundation: It refers to an independent foundation that uses a single pile (usually a large-diameter pile) to bear and transfer the load of the upper structure (usually a column). Group-pile foundation: It refers to a pile foundation composed of more than two rows of piles. Foundation pile: It refers to a single pile in a group-pile foundation. In engineering surveying, a foundation pile refers to concrete with a cylindrical metal on the top surface as a measuring point. For the high-strain dynamic detection of building foundation piles, by using a heavy hammer to impact from the top of the foundation pile and cooperating with sensors on the side of the foundation pile, the vertical compressive bearing capacity of the foundation pile and the integrity of the pile body are detected.

[0003] In the existing building foundation pile detection device, during use, a heavy hammer is usually used to impact the top surface of the foundation pile from the top, and the overall vibration of the foundation pile caused by the impact is fed back to the sensors on the side, so as to draw the impact vibration acceleration curve of the foundation pile. However, in actual detection, the flatness of the top surface of the foundation pile is poor, and when actually colliding with the heavy hammer, the force on the collision point is uneven. At the same time, the concrete fragments on the top are broken and ejected under the impact, and there is a risk of concrete ejection in the actual detection environment, which greatly reduces the quality of the foundation pile detection and poses a detection safety risk, and the use effect is not good.

[0004] In addition, in the existing building foundation pile detection device, during use, sensors on both sides are usually attached to both sides of the foundation pile, and the high-strain dynamic detection of the foundation pile is completed during the collision vibration process. However, in actual use, for the fixed attachment of the sensors, the sensors are usually fixed and attached to the side of the foundation pile by means of surrounding bundling. However, in actual bundling, loosening occurs during the vibration process, resulting in a poor actual contact effect of the sensors, inaccurate detection data for the foundation pile, and greatly reducing the final detection data, and the detection effect is poor. Summary of the Invention

The top surface of the two installation frames is fixedly installed with an installation rack. The top surface of the inner surface of the installation rack is fixedly installed with a lifting rod. The lower end of the lifting rod is fixedly installed with a heavy hammer. A limiting ring is fixedly sleeved on the outer surface of the heavy hammer.

The outer surface of the sleeve rod is movably sleeved with the limiting ring. A locking cap is threadedly sleeved on the outer surface of the sleeve rod. The bottom surface of the sleeve ring is fixedly connected with a connecting rod. The bottom surface of the connecting rod is fixedly connected with a mounting plate. The top surface of the mounting plate is fixedly installed with a motor frame. The top surface of the motor frame is fixedly installed with a motor. The output shaft of the motor is fixedly connected with a rotating shaft. The lower end of the rotating shaft passes through the mounting plate and is fixedly connected with a grinding disc.

The top surface of the detection box is fixedly connected with a connecting wire. The outer end of the connecting wire is fixedly connected with a sensor.

[0007] First embodiment: As Figure 1 , Figure 2 and Figure 4 shown, move the device to the outside of the foundation pile, keep the heavy hammer directly above the foundation pile, put the sleeve ring into the bottom of the heavy hammer, and make the sleeve rod on the top surface of the sleeve ring movably sleeved with the limiting ring on the outer surface of the heavy hammer and tighten the locking cap. Start the motor to drive the grinding disc to rotate, and start the lifting rod to make the grinding disc close to the top of the foundation pile to complete grinding and leveling.

[0008] First, by fixedly sleeving a limiting ring on the outer surface of the heavy hammer, sleeving the sleeve ring on the outer surface of the heavy hammer, using the sleeve ring to cooperate with the connecting rod to connect with the mounting plate, and adding a motor on the top surface of the mounting plate, connecting the motor with the rotating shaft and making the rotating shaft fixedly connected with the grinding disc. While controlling the movement of the heavy hammer by the lifting rod controlled by the up and down movement of the heavy hammer, using the installation of the sleeve ring on the heavy hammer to realize the follow-up movement of the sleeve ring, so as to control the grinding disc to move down and grind the top surface of the foundation pile, so that the top surface of the foundation pile is effectively leveled, and the sleeve ring and other structures can be conveniently removed after the foundation pile is leveled for high-quality high-strain detection. During actual detection, the contact surface is sufficient, the detection quality is improved, and the use effect is good.

[0009] Preferably, a communicating rod is fixedly installed on the bottom surface of the inner surface of the installation frame. One end of the communicating rod is movably sleeved with a push rod. The outer end of the push rod is fixedly connected with a placement frame. The inner surface of the placement frame is movably sleeved with the sensor. A control mechanism is fixedly installed on the front surface of the connecting plate. By using the placement frame to place the sensor and controlling the movement of the push rod, the movement control of the sensor in the placement frame is realized.

[0010] Preferably, a spring is fixedly connected inside the connecting rod. The movable end of the spring is fixedly connected with a movable plug, and the movable plug is fixedly connected with the push rod. By utilizing the elasticity of the spring, when resetting the control mechanism, the push rod is reset as the spring elastically resets.

[0011] Preferably, the other end of the connecting rod is fixedly communicated with one end of a bent pipe, and the other end of the bent pipe is communicated with the control mechanism. By using the bent pipe to squeeze the pressure oil into the connecting rod, the internal hydraulic pressure of the connecting rod is increased, thereby pushing the push rod to move.

[0012] Preferably, the control mechanism includes a storage cylinder, a threaded hole, a threaded rod, and a push plate. The storage cylinder is fixedly installed on the front surface of the connecting plate. The threaded hole is opened on the end surface of the storage cylinder. The outer surface of the threaded rod is threadedly sleeved with the threaded hole. The push plate is fixedly connected to the end surface of the threaded rod. The push plate is movably sleeved inside the storage cylinder. By controlling the control mechanism to supply the pressure oil, the movement of the push rod is controlled, and the contact control between the sensor and the foundation pile is completed. The storage cylinder stores the pressure oil, and the rotation of the threadedly sleeved threaded rod drives the push plate to rotate and move horizontally, and the pressure oil is squeezed into the bent pipe.

[0013] Preferably, an installation groove is opened on the inner side surface of the placement frame, and a first magnetic plate is fixedly sleeved on the inner surface of the installation groove. The first magnetic plate is magnetically adsorbed with the sensor. By using the first magnetic plate in the installation groove, the sensor placed in the placement frame is adsorbed by the magnetic effect, improving the placement stability.

[0014] Preferably, side grooves are opened on the side surfaces of the inner surface of the installation frame. A metal plate is fixedly sleeved on the inner side surface of the side grooves. A wire arranging mechanism is movably sleeved on the inner surface of the side grooves. A limiting plate is fixedly connected to the inner surface of the side grooves. By movably sleeving the side grooves with the wire arranging mechanism, the wire arranging mechanism has stable up and down movement control. At the same time, the limiting plate is used to control the limit position of the downward movement. When the sensor moves and contacts the foundation pile, the wire arranging mechanism moves to the top of the limiting plate, and at the same time, the connecting wire is tightened, avoiding the wire arranging mechanism from moving downward during the collision detection vibration.

[0015] Preferably, the wire aligning mechanism includes mounting rods, intermediate rods, rotating wheels, end face grooves and second magnetic plates. There are two mounting rods, and one ends of the two mounting rods are movably sleeved inside the side grooves. The intermediate rod is fixedly connected between the two mounting rods. The rotating wheel is movably sleeved on the outer surface of the intermediate rod. The end face groove is formed on the end face of the intermediate rod. The second magnetic plate is fixedly sleeved inside the end face groove. By using the adsorption of the second magnetic plate in the wire aligning mechanism to the metal plate, the magnetic effect is utilized to ensure that the wire aligning mechanism can be conveniently controlled to move up and down and be stably fixed at one place, realizing the height adjustment of the wire aligning mechanism, thereby completing the tension control of the connecting wire. Moreover, by sleeving the inner surface of the rotating wheel with the connecting wire, the friction during tensioning the connecting wire is reduced, and the convenience of tension control is improved.

[0016] Second Embodiment: As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 shown, after finishing grinding, unscrew the locking cap and remove the collar, adjust the control mechanism so that the pressure oil in the control mechanism enters the connecting rod, and the oil pressure in the connecting rod increases, thereby pushing the push rod and the placement frame to move, and then making the sensor placed in the placement frame move and clamp the side of the foundation pile, and start the lifting rod and control the weight to repeatedly strike the top surface of the foundation pile to complete the detection; before the detection, place the sensor in the placement frame, and wind the connecting wire around the rotating wheel on the wire aligning mechanism. After the detection is completed, reset the control mechanism so that the push rod drives the placement frame to reset, and push up the wire aligning mechanism so that the wire aligning mechanism moves up along the side groove and is adsorbed and fixed on the metal plate by the second magnetic plate at the end face of the wire aligning mechanism to keep the connecting wire taut, and at the same time, the sensor is lifted to one side of the wire aligning mechanism.

[0017] First, by using the additional connecting rod, movably sleeving the push rod in the connecting rod, and adding a control mechanism to cooperate with the curved pipe to squeeze the pressure oil into the inside of the connecting rod, the increased oil pressure is used to realize the movement of the push rod movably sleeved in the connecting rod, thereby driving the placement frame to move closer to the foundation pile, and cooperating with the sensor placed in the placement frame, realizing that the sensor is stably attached to the side of the foundation pile. During the detection, it is ensured that the sensor is in good contact with the foundation pile, thereby ensuring a stable detection effect and greatly improving the actual detection accuracy.

[0018] In addition, by opening side grooves on the inner surface of the installation frame and using the metal plates in the side grooves to adsorb the wire arranging mechanism sleeved in the side grooves, the rotating wheel in the wire arranging mechanism is effectively utilized to sleeved the connecting wire. By adjusting the position of the wire arranging mechanism, the connecting wire is always in a tensioned state, avoiding the dragging and winding of the loose connecting wire, improving the wire arranging effect. After the detection is completed, by raising the height of the wire arranging mechanism, the sensor at one end of the connecting wire is lifted, so that the sensor is suspended on one side of the wire arranging mechanism, realizing convenient wire arranging. While keeping the connecting wire tensioned, the stable placement of the sensor is achieved.

[0019] A detection method for a building foundation pile detection device includes the following operation steps:

[0020] The first step: Move the device to the outside of the foundation pile, keep the heavy hammer directly above the foundation pile, sleeved the collar along the bottom of the heavy hammer, and make the sleeve rod on the top surface of the collar movably sleeved with the limit ring on the outer surface of the heavy hammer. Screw the locking cap on the sleeve rod, start the motor to drive the grinding disc to rotate, and start the lifting rod to make the grinding disc approach the top of the foundation pile to complete grinding and leveling.

[0021] The second step: After grinding, unscrew the locking cap and remove the collar, adjust the control mechanism to make the pressure oil in the control mechanism enter the connecting rod, and push the push rod and the placement frame to move, so that the sensor placed in the placement frame moves and clamps the side of the foundation pile, and start the lifting rod and control the heavy hammer to repeatedly strike the top surface of the foundation pile to complete the detection.

[0022] The third step: Before detection, place the sensor in the placement frame and make the connecting wire wound around the rotating wheel on the wire arranging mechanism. After the detection is completed, reset the control mechanism to make the push rod drive the placement frame to reset, and push up the wire arranging mechanism to make the wire arranging mechanism move up along the side groove and adsorb and fix on the metal plate, keep the connecting wire tensioned, and at the same time lift the sensor to one side of the wire arranging mechanism.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention fixedly sleeved the limit ring on the outer surface of the heavy hammer, sleeved the collar on the outer surface of the heavy hammer, connected the collar with the connecting rod and the mounting plate, added a motor on the top surface of the mounting plate, connected the motor with the rotating shaft, and made the rotating shaft fixedly connected with the grinding disc. While controlling the movement of the heavy hammer by the lifting rod controlled by the up and down movement of the heavy hammer, the collar is installed with the heavy hammer to realize the follow-up movement of the collar, thereby controlling the grinding disc to move down and grind the top surface of the foundation pile, so that the top surface of the foundation pile is effectively leveled, and after the foundation pile is leveled, the collar and other structures can be conveniently removed for high-quality high-strain detection. During actual detection, the contact surface is sufficient, improving the detection quality and having a good use effect.

[0025] 2. The present invention utilizes the additional connecting rod, movably sleeving a push rod in the connecting rod, and adding a control mechanism to cooperate with the curved pipe to squeeze the pressure oil into the interior of the connecting rod. The increased oil pressure is used to move the push rod movably sleeved in the connecting rod, thereby driving the placement frame to move closer to the foundation pile. In cooperation with the sensor placed in the placement frame, the sensor is stably attached to the side of the foundation pile. During detection, good contact between the sensor and the foundation pile is ensured, thus ensuring a stable detection effect and greatly improving the actual detection accuracy.

[0026] 3. The present invention opens a side groove on the inner surface of the installation frame and adsorbs the metal plate in the side groove with the wire arranging mechanism sleeved in the side groove. The rotating wheel in the wire arranging mechanism is effectively utilized to sleeve the connecting wire. By adjusting the position of the wire arranging mechanism, the connecting wire is always in a tension state, avoiding dragging and winding of the loose connecting wire, improving the wire arranging effect. After the detection is completed, by raising the height of the wire arranging mechanism, the sensor at one end of the connecting wire is lifted, so that the sensor is suspended on one side of the wire arranging mechanism, realizing convenient wire arranging, maintaining the tension of the connecting wire and realizing the stable placement of the sensor at the same time.

And the inner surface of the rotating wheel 323 is sleeved with the connecting wire 5 to reduce the friction when tensioning the connecting wire 5 and improve the convenience of the tension control.

[0047] Second Embodiment: As Figure 1 、 Figure 2 、Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown in Figure 8 , after finishing grinding, unscrew the locking cap 13 and remove the collar 11, adjust the control mechanism 25 so that the pressure oil in the control mechanism 25 enters the connecting rod 20, and increase the oil pressure in the connecting rod 20, thereby pushing the push rod 21 and the placement frame 24 to move, and then making the sensor 6 placed in the placement frame 24 move and clamp the side of the foundation pile, and start the lifting rod 8 and control the weight 9 to repeatedly strike the top surface of the foundation pile to complete the detection; before the detection, place the sensor 6 in the placement frame 24, and make the connecting wire 5 wind around the rotating wheel 323 on the wire arranging mechanism 32.

[0048] First of all, by using the added connecting rod 20, the push rod 21 is movably sleeved in the connecting rod 20, and the control mechanism 25 is added to cooperate with the curved pipe 26 to squeeze the pressure oil into the inside of the connecting rod 20, and the added oil pressure is used to realize the movement of the push rod 21 movably sleeved in the connecting rod 20, thereby driving the placement frame 24 to move and approach the foundation pile, and cooperating with the sensor 6 placed in the placement frame 24, realizing that the sensor 6 stably adheres to the side of the foundation pile. During the detection, it is ensured that the sensor 6 is in good contact with the foundation pile, thereby ensuring a stable detection effect and greatly improving the actual detection accuracy.

[0049] In addition, by opening the side groove 29 on the inner surface of the installation frame 1 and adsorbing the metal plate 30 in the side groove 29 and the wire arranging mechanism 32 sleeved in the side groove 29, the rotating wheel 323 in the wire arranging mechanism 32 is effectively used to sleeve the connecting wire 5. By adjusting the position of the wire arranging mechanism 32, the connecting wire 5 is always in a taut state, avoiding the dragging and winding of the loose connecting wire 5, improving the wire arranging effect, and after the detection is completed, by raising the height of the wire arranging mechanism 32, the sensor 6 at one end of the connecting wire 5 is lifted, so that the sensor 6 is suspended on one side of the wire arranging mechanism 32, realizing convenient wire arranging, keeping the connecting wire 5 taut and at the same time realizing the stable placement of the sensor 6.

[0051] Step 1: Move the device to the outside of the foundation pile, keep the weight hammer 9 directly above the foundation pile, slip the collar 11 onto the bottom of the weight hammer 9, and make the sleeve rod 12 on the top surface of the collar 11 movably sleeved with the limit ring 10 on the outer surface of the weight hammer 9. Screw the locking cap 13 onto the sleeve rod 12, start the motor 17 to drive the grinding disc 19 to rotate, and start the lifting rod 8 to move the grinding disc 19 close to the top of the foundation pile to complete grinding and leveling.

[0052] Step 2: After grinding, unscrew the locking cap 13 and remove the collar 11. Adjust the control mechanism 25 to make the pressure oil in the control mechanism 25 enter the connecting rod 20, and push the push rod 21 and the placement frame 24 to move, so that the sensor 6 placed in the placement frame 24 moves and clamps the side of the foundation pile.
