Description

Technical Field

[0001] This invention relates to the field of pile foundation construction equipment, and in particular to a guiding device for preventing retaining piles from tilting or deviating. Background Technology

[0002] With subway construction in full swing across the country, the open-cut method, with its advantages of speed, economy, and safety, has become the preferred excavation technology for subway construction. To ensure construction safety during open-cut foundation pit construction, dynamic monitoring of the inclination of the retaining piles is essential. The main purpose is to understand the potential impact of ground displacement and stress during deep open-cut foundation pit construction before construction begins, clarifying the magnitude and scope of these impacts, identifying the locations and methods of potential hazards, and determining the corresponding construction countermeasures. Simultaneously, it provides management benchmarks and basis for on-site monitoring and measurement.

[0003] In existing applications, in order to detect the inclination of the retaining piles in the foundation pit, positioning and inclination measurement technology (inclinometer) is required. Stable inclinometer tubes are set up and inclinometers are used for observation, which can obtain accurate data on the inclination of the underground structure.

[0004] According to the design requirements, the inclinometer tube used to monitor the tilt of the retaining pile is set on the back side of the soil. The monitoring personnel have to climb over the retaining railing to the capping beam to carry out the monitoring work, which is extremely inconvenient and poses a safety hazard. The operation is troublesome and it is difficult to accurately obtain the direction and angle of the retaining pile tilt. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention provides a guiding device for preventing the retaining piles from tilting or deviating.

[0006] The technical solution includes a housing, inside which is a positioning component. The top of the positioning component is equipped with a microcontroller, a controller, and a power supply. The middle of the positioning component is equipped with a measuring component for detecting the tilt angle of the retaining pile. Between the measuring component and the positioning component is an adjusting component for adjusting the measuring component to the tilt direction of the retaining pile. A display screen is fixedly connected to one side of the outer wall of the housing. The microcontroller, controller, and display screen are all electrically connected to the power supply. The display screen is electrically connected to the controller.

[0007] Preferably, the positioning component includes two circular rings located inside the housing, and a positioning ring with a cross-sectional shape of U is fixedly connected to the outside of the two circular rings. The positioning ring is fixedly connected to the inner wall of the housing, and there is a gap between the two circular ring supports.

[0008] Preferably, the adjusting component includes a transmission plate located between two rings, the transmission plate not being in contact with the rings, a first counterweight fixedly connected to one end of the transmission plate at the positioning ring, a transmission ring fixedly connected to the end of the transmission plate away from the first counterweight, the transmission ring being slidably connected to the rings, a first rod fixedly connected to the middle of the transmission ring, and two symmetrically distributed arc-shaped hollow rods fixedly connected to the outer circumference of the transmission ring.

[0009] Preferably, the measuring assembly includes two curved hollow rods with their top ends fixedly connected to a bent hollow rod. Two symmetrically distributed pressure sensors are fixedly connected inside the bent hollow rod. The microcontroller and controller are both electrically connected to the pressure sensors. A first piston is attached to the input end of each pressure sensor. A spring is fixedly connected to the end of the first piston away from the pressure sensor. A second piston is fixedly connected to the end of the spring away from the first piston. Both the first and second pistons are slidably connected to the curved hollow rods. An arc rod is fixedly connected to the side of the second piston away from the spring. The first piston, the second piston, and the arc rod are all slidably connected to the curved hollow rod. A second counterweight is fixedly connected between the two arc rods. A second rod is fixedly connected to the top of the second counterweight. The first rod passes through the second rod and is rotatably connected to the second rod.

[0010] Preferably, a connecting pipe is fixedly connected between the two arc-shaped hollow rods, and a cavity is formed between the connecting pipe, the arc-shaped hollow rods, the first piston, and the second piston, and the cavity is filled with a viscous liquid.

[0011] Preferably, a compass module is fixedly connected to the bottom of the connecting pipe, and the compass module is electrically connected to the controller.

[0012] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows: 1. The box is placed on the top or side wall of the retaining pile for fixation. The first counterweight will drive the arc-shaped hollow rod to rotate to the direction of the retaining pile's deviation. The direction of the retaining pile's deviation is obtained with the help of the compass module. Then, the second counterweight in the measuring component will rotate under the action of gravity, thereby driving the spring to compress. The pressure sensor senses the elastic force generated when the spring is compressed, thereby calculating the angle of the retaining pile's deviation. Finally, the direction and angle of the retaining pile's deviation are displayed on the screen in the form of text, so that the surveyor can obtain the value of the direction and angle of the retaining pile's deviation from a distance, so as to perform preprocessing in a timely manner.

[0013] 2. When the second counterweight moves the arc rod, the arc rod will move the second piston, thereby pushing the viscous liquid inside the chamber. The viscous liquid is used to prevent the device from tilting due to slight vibration, thus ensuring the stability of the detection.

[0014] 3. Compared with existing devices for detecting the tilt angle of retaining piles, this guiding device can obtain the numerical values ​​of the direction and angle of the tilt of the retaining piles. It can be used simply by placing the box on the retaining pile or fixing it to the outer wall of the retaining pile. It is simple to operate, convenient to use, and reduces safety hazards.

[0023] Example 1

[0024] See Figures 1 to 3 This invention provides a guiding device for preventing the tilting and deviation of retaining piles, comprising a housing 1, a positioning component 2 inside the housing 1, a microcontroller 3, a controller 4 and a power supply 5 on the top of the positioning component 2, a measuring component 6 for detecting the tilting and deviation angle of the retaining pile in the middle of the positioning component 2, an adjusting component 7 between the measuring component 6 and the positioning component 2 for adjusting the measuring component 6 to the tilting and deviation direction of the retaining pile, and a display screen 8 fixedly connected to one side of the outer wall of the housing 1. The microcontroller 3, the controller 4 and the display screen 8 are all electrically connected to the power supply 5, and the display screen 8 is electrically connected to the controller 4.

[0025] By fixing the housing 1 on top of or to the side of the retaining pile, when the retaining pile tilts, the adjusting component 7 on the positioning component 2 drives the measuring component 6 to rotate in the direction of the tilt of the retaining pile. Then the measuring component 6 measures the angle of tilt of the retaining pile. When the measuring component 6 sends the angle value of the tilt of the retaining pile to the controller 4, the controller 4 displays the tilt angle in digital form on the display screen 8. When this guiding device is in use, no matter which direction the retaining pile tilts, it can measure the angle of tilt and display it digitally on the display screen 8 for easy observation by the operator.

[0026] Preferably, the positioning component 2 includes two circular rings 9 located inside the housing 1, and a positioning ring 10 with a cross-sectional shape of U is fixedly connected to the outside of the two circular rings 9. The positioning ring 10 is fixedly connected to the inner wall of the housing 1, and there is a gap between the two circular rings 9.

[0027] The ring 9 is fixed to the housing 1 by the positioning ring 10, which facilitates the support of the adjustment component 7 and prevents the adjustment component 7 from contacting the housing 1.

[0028] Preferably, the adjusting component 7 includes a transmission plate 11 located between two circular rings 9. The transmission plate 11 is not in contact with the circular rings 9. A first counterweight 12 is fixedly connected to one end of the transmission plate 11 located on the positioning ring 10. A transmission ring 13 is fixedly connected to the end of the transmission plate 11 away from the first counterweight 12. The transmission ring 13 is slidably connected to the circular rings 9. A first rod 14 is fixedly connected to the middle of the transmission ring 13. Two symmetrically distributed arc-shaped hollow rods 15 are fixedly connected to the outer circumference of the transmission ring 13.

[0029] By adjusting component 7, when the retaining pile tilts, the box 1 on the retaining pile tilts, and the box 1 causes the positioning ring 10 and the circular ring 9 to tilt, so that the transmission ring 13 tilts when it is located on the positioning ring 10 and the circular ring 9. Due to the first counterweight 12, the first counterweight 12 will drive the transmission plate 11 to slide to the lowest point of the positioning ring 10. At this time, the transmission plate 11 drives the transmission ring 13 to slide between the two circular rings 9. The transmission ring 13 drives the arc-shaped hollow rod 15 to rotate, thereby adjusting the measuring component 6 to a position where the tilt angle of the retaining pile can be measured.

[0030] Preferably, the measuring component 6 includes two curved hollow rods 15 with their top ends fixedly connected to a bent hollow rod 16. Two symmetrically distributed pressure sensors 17 are fixedly connected inside the bent hollow rod 16. The microcontroller 3 and the controller 4 are both electrically connected to the pressure sensors 17. A first piston 18 is attached to the input end of each pressure sensor 17. A spring 19 is fixedly connected to the end of the first piston 18 away from the pressure sensor 17. A second piston 20 is fixedly connected to the end of the spring 19 away from the first piston 18. Both the first piston 18 and the second piston 20 are slidably connected to the curved hollow rods 15. An arc rod 21 is fixedly connected to the side of the second piston 20 away from the spring 19. The first piston 18, the second piston 20, and the arc rod 21 are all slidably connected to the curved hollow rods 15. A second counterweight 22 is fixedly connected between the two arc rods 21. A second rod 23 is fixedly connected to the top end of the second counterweight 22. The first rod 14 passes through the second rod 23 and is rotatably connected to the second rod 23.

[0031] When the curved hollow rod 15 rotates, it drives the bent hollow rod 16 and the arc rod 21 to rotate around the second rod 23. Since the second counterweight 22 is vertically downward under the action of gravity, at this time, the second counterweight 22 drives the second rod 23 to rotate on the first rod 14. At the same time, the second counterweight 22 drives the arc rod 21 to slide inside the curved hollow rod 15. The arc rod 21 pushes the second piston 20 to move towards the first piston 18. The second piston 20 drives the spring 19 to compress. The spring 19 pushes the first piston 18 towards the pressure sensor 17 through its elastic force. The pressure sensor 17 transmits the sensed analog signal to the microcontroller 3. The microcontroller 3 converts the analog signal into a digital signal and transmits it to the controller 4. The controller 4 processes the value of the digital signal to obtain the angle of deflection of the second counterweight 22, thereby obtaining the angle of deflection of the retaining pile. Finally, the specific value is displayed on the display screen 8 in text form for the observer to observe.

[0032] Preferably, a connecting pipe 24 is fixedly connected between the two arc-shaped hollow rods 15. A cavity is formed between the connecting pipe 24, the arc-shaped hollow rods 15, the first piston 18, and the second piston 20. The cavity is filled with a viscous liquid 25. The viscous liquid 25 fills the cavity so that the second piston 20 pushes the viscous liquid 25 when it pushes the spring 19. The viscosity of the viscous liquid 25 is used to prevent the device from tilting due to slight vibration, thus ensuring the stability of the detection.

[0033] Preferably, a compass module 26 is fixedly connected to the bottom of the connecting pipe 24. The compass module 26 is electrically connected to the controller 4. The connecting pipe 24 is rotated by the arc-shaped hollow rod 15, and the connecting pipe 24 drives the compass module 26 to rotate. The compass module 26 then calculates the angle between the connecting pipe 24 and the due south direction, thereby determining the angle and direction of the retaining pile.

[0034] Preferably, the controller 4 is model F3SP59-7S.

[0035] Preferably, the pressure sensor 17 is model PT124G-116.

[0036] Preferably, the microcontroller 3 is model M68HC16.

[0037] Preferably, the compass module 26 is model LSM303DLHC.

[0038] When using this invention, the box 1 is placed on top of or fixed to the side wall of the retaining pile. The first counterweight 12 will drive the arc-shaped hollow rod 15 to rotate to the direction of the retaining pile's tilt. With the help of the compass module 26, the direction of the retaining pile's tilt is obtained. Then, the second counterweight 22 in the measuring component 6 will rotate under the action of gravity, thereby driving the spring 19 to compress. The pressure sensor 17 senses the elastic force generated when the spring 19 is compressed and transmits the signal to the display screen 8 through the controller 4. The tilt angle is displayed on the display screen 8 in the form of text, so that the surveyor can obtain the value of the direction and angle of the retaining pile's tilt from a distance for timely preprocessing.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
