Technical Field

Background Art

[0002] Pile foundation plays a vital role in all aspects of the construction industry, and the stability of the pile foundation also affects the safety of the superstructure. The displacement of the pile foundation will be affected by the soft foundation, rock properties, and groundwater level in geological conditions. Because of such complex environmental factors, in order to reduce the reduction of project quality and the impact on economic life caused by the displacement of the pile foundation, the displacement monitoring of the pile foundation is the top priority after the completion of the project.

[0027] like Figure 1-4 As shown, a real-time monitoring and correction compensation device for pile foundation offset described in the utility model, wherein: it includes a base 7, a dustproof acrylic cover 1 fixed on the base 7, the dustproof acrylic cover 1 and the base 7 form a closed installation cavity, an integrated circuit board 6 in the inner cavity of the installation cavity, three stress induction motors 4 electrically connected to the integrated circuit board 6 through a motor power supply line 5, the stress induction motor 4 includes a stress induction motor body 401, a rotating shaft arranged on the stress induction motor body 401, a wire wheel 402 fixed on the rotating shaft, and the three wire wheels 402 are respectively connected to the steel ball a3 through three high-strength composite wires 2;

[0028] The steel ball a3 is fixedly connected to one end of another high-strength composite wire 2, and the other end of the high-strength composite wire 2 is fixed to the inner wall of the dustproof acrylic cover 1, so that the steel ball a3 is suspended in the inner cavity of the dustproof acrylic cover 1;

[0029] The integrated circuit board 6 is electrically connected to the angle correction compensation device 14 through a wire, and the angle correction compensation device 14 includes a low-friction panel 1402 integrated with a data power supply circuit, a universal shaft 1404 fixed on the top surface of the low-friction panel 1402 integrated with a data power supply circuit, a stress sensor 1401 connected to the universal shaft 1404, and a steel ball b1405 connected to the stress sensor 1401 through a wire, and the weight of the steel ball b1405 is less than the weight of the steel ball a3;

[0030] The integrated circuit board 6 is electrically connected to an external power source. In this embodiment, the other end of the high-strength composite wire 2 is fixed to the top of the inner wall of the dustproof acrylic cover 1 through a wire loop 13. The integrated circuit board 6 controls the stress induction motor 4 to perform real-time monitoring, and the integrated circuit board 6 controls the angle correction compensation device 14 to perform angle correction compensation. This solution realizes real-time monitoring, timely correction compensation, reduces the subsequent maintenance cost, and reduces the labor intensity of workers' monitoring.

[0031] To facilitate the electrical connection between the low-friction panel 1402 integrated with the data power supply circuit and the integrated circuit board 6, further, in the above scheme: a data transmission and power transmission port 1403 is provided on the low-friction panel 1402 integrated with the data power supply circuit, and the data transmission and power transmission port 1403 is electrically connected to the angle compensation device power supply and data transmission port 606 provided on the integrated circuit board 6 through a wire.

[0032] In order to facilitate the signal transmission of the integrated circuit board 6 and control the opening and closing of the stress induction motor 4, in the above embodiment, preferably: the integrated circuit board 6 is provided with a stress induction motor power supply and data transmission interface 601, a SIM card slot 602, an integrated circuit board power supply interface 603, a wireless module 604 and a data storage and calculation unit 605, the stress induction motor power supply and data transmission interface 601 is electrically connected to the stress induction motor 4 through the motor power supply line 5, and the integrated circuit board power supply interface 603 is electrically connected to the external power supply.

[0033] In order to realize the electrical connection between the integrated circuit board 6 and the external power supply, in the above embodiment, preferably: the integrated circuit board power supply interface 603 is electrically connected to the external power supply interface 8 through a wire, and the external power supply interface 8 is located on the base 7, and the external power supply interface 8 is connected to the solar cell 11 through the solar panel power supply line 9.

[0034] To effectively ensure the control accuracy, in the above embodiment, preferably: the weight of the steel ball b1405 is 0.5kg, and the weight of the steel ball a3 is 2kg. In this embodiment, the position of the steel ball b1405 is for displacement direction correction. Due to the influence of its own gravity, the direction of the steel ball b1405 keeps rotating. Its weight of 1kg is designed based on the lubricity of the bearing. Since the steel ball a3 is suspended in mid-air, it needs to have a larger weight to straighten the high-strength composite wire and reduce the error caused by the material, so the steel ball a3 is 2kg.

[0035] To reduce the adsorption error, further, in the above scheme: the steel ball b1405 and the steel ball a3 are both solid steel balls. In this embodiment, the steel ball b1405 and the steel ball a3 are both solid steel balls to eliminate the influence of static electricity, which will cause the adsorption error to increase.

[0036] The working process of the above structure is as follows: the device described in this scheme is placed at the top horizontal position of the foundation of the pile foundation 12. The three stress induction motors 4 of the pile foundation 12 are arranged around the base at an angle of 120°. The stress induction motor 4 can sense 0-0.5N stress through the wire wheel 402, and the device starts self-checking every hour. When the stress induction motor 4 starts the wire wheel 402 to rotate without feeling stress, it will rotate the wire 402 to wind the high-strength composite wire 2 until the stress induction limit of 0.5N is exceeded. At the same time, the stress induction motor 4 transmits the rotation data of the wire wheel 402 to the data storage calculation unit 605 on the integrated circuit board 6 through the data transmission line (i.e. the above-mentioned wire). The data storage calculation unit 605 calculates the offset angle of the pile foundation 12 by calculating the length of the wire wheel 402 after winding and the length of the four high-strength composite wires 2 connected to the steel ball a3. Then the data is transmitted to the receiver's terminal in real time through the wireless module 604 on the integrated circuit board 6, and the wireless module 604 adopts a Bluetooth module. At the same time, the equipment of this scheme can perform angle correction and compensation. When the equipment monitors the offset angle and offset direction in real time, the correction and compensation are also running. When the pile foundation 12 is offset, the steel ball b1405 of the angle correction and compensation device 14 will be affected by the downward force, and the rope 15 will transmit the downward force of the steel ball b1405 to the stress sensor 1401. The stress sensor 1401 converts the downward force into an angle through sine and cosine conversion (calculation of the downward force component and the dead weight of the steel ball b1405, and the friction resistance of the low friction resistance panel 1402 integrated with the data power supply line must be added during the calculation process) (the angle correction and compensation device 14 cannot monitor the direction of pile foundation offset). When the angle calculated by the angle correction and compensation device 14 is inconsistent with the angle calculated by the integrated circuit board 6, the stress induction motor 4 on the integrated circuit board 6 will start the self-test program to increase the stress of the stress induction motor 4 to about 2N, and straighten the high-strength composite wire 2 for angle correction and compensation. The bottom of the base 12 is a slightly inclined flat plate to prevent rainwater from penetrating. The dustproof acrylic cover 1 has the functions of dustproof, rainproof and windproof. The solar panel 11 supplies power to the entire device. The solar panel 11 is placed on the pile foundation wall. During the specific implementation, the power supply facilities of the equipment described in this scheme must be waterproofed, and the waterproofing treatment can be carried out by conventional treatment.

[0037] All the above-mentioned components are commercially available products, and the description of program control is provided to help those skilled in the art understand the solution described in the utility model.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
