Description

Technical Field

[0001] This utility model relates to the field of pile stress monitoring technology, specifically a stress monitoring device for anti-deformation anchored piles. Background Technology

[0002] With the continuous development of urban construction, the development and utilization of underground space is increasing, and deep foundation pit engineering is becoming more and more common. The construction of high-rise buildings, subway stations, underground shopping malls, and other projects requires the excavation of numerous deep foundation pits. To ensure the safety of surrounding buildings, underground pipelines, and roads, while also ensuring the stability of the foundation pit itself, anchored piles are often used as an effective support structure. Anchored piles bear loads such as earth pressure and water pressure through the piles themselves, while the anchor rods provide tension; together, they maintain the stability of the foundation pit.

[0003] Deep foundation pit engineering carries high risks. Accidents can severely damage the project itself and endanger the surrounding environment and personnel safety. Existing anchored pile systems cannot monitor their stress state, posing certain safety hazards.

[0004] To address the aforementioned issues, a stress monitoring device for anti-deformation anchored piles is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a stress monitoring device for anti-deformation anchored piles, which solves the problem that existing anchored piles in the background art cannot monitor their stress state and have certain safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stress monitoring device for anti-deformation anchored piles, comprising a soil body, a foundation pit on the left side of the soil body, evenly distributed piles on the inner wall of the foundation pit, two waist beams on the outer side of the piles, multiple anchoring components fixedly connected inside the soil body, the anchoring components penetrating the piles and waist beams on the left side, a first pressure sensor fixedly connected to the left side of the piles, a second pressure sensor fixedly connected to the right side of the piles, the second pressure sensor being located on the outer side of the soil body, a resistance strain gauge sensor fixedly connected inside the piles, a monitoring platform outside the foundation pit, a display screen fixedly connected to the top of the monitoring platform, a computer inside the monitoring platform, an alarm fixedly connected to the front right side of the top of the monitoring platform, a controller fixedly connected to the rear right side of the top of the monitoring platform, and a displacement sensor fixedly connected to the top of the piles.

[0007] By adopting the above technical solution, the data collected by each sensor is transmitted to the data acquisition unit on the top left of the monitoring station. After preliminary processing and integration of the data, the data acquisition unit transmits it to the computer inside the monitoring station. By comparing data such as pressure, strain, anchor bolt tension, and displacement with preset safety thresholds, it is determined whether the stress and deformation of the anchor piles are in a normal state.

[0008] As a further description of the above technical solution: the anchor assembly includes an anchor body, which is set in the soil. An anchor rod is fixedly connected to the left side of the anchor body. The anchor rod penetrates the soil, the pile and the waist beam. An anchor is provided at the end of the anchor rod, and a pad is provided inside the anchor.

[0009] By adopting the above technical solution, the anchor bolt assembly can limit and fix the pile. When the soil pressure attempts to push the pile to deform, the anchor bolt bears the tension. By analyzing the stress and deformation of the anchor bolt, the magnitude of the anchor bolt tension can be determined and it can be judged whether it is within the safe range.

[0010] As a further description of the above technical solution: the inner side of the waist beam is provided with multiple evenly distributed grooves, and the grooves correspond to the piles.

[0011] By adopting the above technical solution, the groove can make the waist beam fit more closely with the pile.

[0012] As a further description of the above technical solution: a seepage-proof curtain is provided on the inner side of the pile, and the seepage-proof curtain is located on the outer side of the foundation pit.

[0013] By adopting the above technical solutions, the seepage-proof curtain can prevent groundwater from seeping into the outside of the foundation pit.

[0014] As a further description of the above technical solution: the first pressure sensor is disposed between the pile and the waist beam.

[0015] By adopting the above technical solution, the first pressure sensor can sense the pressure transmitted from the piles to the waist beam.

[0016] As a further description of the above technical solution: support frames are provided below both waist beams, and the support frames are fixedly connected to the piles.

[0017] By adopting the above technical solution, the support frame provides support for the waist beam, thereby enhancing the stability of the entire structure.

[0018] As a further description of the above technical solution: a data acquisition instrument is fixedly connected to the top left side of the monitoring station.

[0019] By adopting the above technical solution, the data acquisition instrument performs preliminary processing and integration of the data before transmitting it to the computer in the monitoring station.

[0020] As a further description of the above technical solution: the pad is set on the outside of the waist beam, and the anchor rod passes through the pad.

[0021] By adopting the above technical solution, the pad plate can enable the tension of the anchor bolt to be transmitted more evenly to the waist beam, and then to the pile, ensuring that the force distribution on the pile is more uniform and avoiding uneven local stress.

The device utilizes a pressure sensor, anchor assembly, resistance strain gauge sensor, displacement sensor, data acquisition unit, controller, alarm, and a waist beam working in concert.

[0030] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0031] Reference Figure 1-4 This utility model discloses a stress monitoring device for anti-deformation anchored piles, comprising a soil body 1, a foundation pit 2 on the left side of the soil body 1, and evenly distributed piles 4 arranged on the inner wall of the foundation pit 2, which serve as supports. Two waist beams 7 are arranged on the outer side of the piles 4, and the waist beams 7 are connected to the piles 4 through multiple evenly distributed grooves 8 on their inner sides, connecting multiple piles 4 into a whole structure, enabling the piles 4 to work together to bear the pressure of the soil body 1, thereby improving the overall stability and bearing capacity of the piles 4. Multiple anchoring components are fixedly connected inside the soil body 1, with the anchoring components penetrating the piles 4 and the waist beams 7 on the left side. A first pressure sensor 11 is fixedly connected to the left side of the piles 4, and a second pressure sensor 12 is fixedly connected to the right side of the piles 4, located on the outer side of the soil body 1. A resistance strain gauge sensor 13 is fixedly connected inside the piles 4, and the resistance value of the resistance strain gauge sensor 13 changes accordingly. By measuring the resistance change, the strain of the piles 4 can be calculated. A monitoring station 15 is installed outside the foundation pit 2. A display screen 16 is fixedly connected to the top of the monitoring station 15 for easy data observation. A computer 17 is installed inside the monitoring station 15. An alarm 20 is fixedly connected to the front right side of the top of the monitoring station 15 to easily alert personnel. A controller 19 is fixedly connected to the rear right side of the top of the monitoring station 15. A displacement sensor 21 is fixedly connected to the top of the pile 4.

[0032] Reference Figure 2 and Figure 3 The anchoring assembly includes an anchor body 5, which is placed inside the soil 1. An anchor rod 6 is fixedly connected to the left side of the anchor body 5. The anchor rod 6 penetrates the soil 1, the pile 4, and the waist beam 7. An anchor 10 is provided at the end of the anchor rod 6. A pad 9 is provided inside the anchor 10. The pad 9 is placed outside the waist beam 7, and the anchor rod 6 penetrates the pad 9. The anchoring assembly can limit and fix the pile 4. When the pressure of the soil 1 attempts to push the pile 4 to deform, the anchor rod 6 bears the tensile force. By analyzing the stress and deformation of the anchor rod 6, the magnitude of the tensile force of the anchor rod 6 can be determined, and it can be judged whether it is within the safe range.

[0033] Reference Figure 1-4Multiple evenly distributed grooves 8 are formed on the inner side of the waist beam 7, and the grooves 8 correspond to the piles 4, allowing the waist beam 7 and the piles 4 to fit more closely. A seepage-proof curtain 3 is installed inside the piles 4 and is located outside the foundation pit 2, preventing groundwater from seeping into the foundation pit 2. A first pressure sensor 11 is installed between the piles 4 and the waist beam 7, sensing the pressure transmitted from the piles 4 to the waist beam 7. Support frames 14 are installed below both waist beams 7, and are fixedly connected to the piles 4, providing support and enhancing the stability of the entire structure. A data acquisition instrument 18 is fixedly connected to the top left side of the monitoring platform 15. After preliminary processing and integration of the data, the data acquisition instrument 18 transmits it to the computer 17 inside the monitoring platform 15.

[0034] Working principle: During operation, the soil 1 exerts pressure on the pile 4. The first pressure sensor 11 is located between the pile 4 and the waist beam 7, which can sense the pressure transmitted from the pile 4 to the waist beam 7. The second pressure sensor 12 is set on the outside of the soil 1 on the right side of the pile 4 to monitor the pressure of the soil 1 on the pile 4. The two sensors acquire pressure data from different directions to comprehensively reflect the soil pressure on the pile 4. When the pile 4 undergoes a slight deformation under stress, the resistance value of the resistance strain sensor 13 will change accordingly. By measuring the change in resistance, the strain of the pile 4 can be calculated, and thus the internal stress state of the pile 4 can be known. In the anchor assembly, one end of the anchor rod 6 is anchored in the stable soil 1 through the anchor body 5, and the other end passes through the pile 4 and the waist beam 7. The anchor 10 and the pad 9 at the end fix the anchor rod 6. When the soil pressure 1 attempts to deform the pile 4, the anchor rod 6 bears tensile force. By analyzing the stress and deformation of the anchor rod 6, the magnitude of the tensile force can be determined, and it can be judged whether it is within the safe range. The displacement sensor 21 at the top of the pile 4 monitors the horizontal and vertical displacement of the top of the pile 4 in real time. Once the pile 4 is displaced due to force, the displacement sensor 21 records the data, which is an important basis for judging the overall stability of the pile 4. The data collected by each sensor is transmitted to the data acquisition instrument 18 on the top left of the monitoring station 15. After preliminary processing and integration of the data, the data acquisition instrument 18 transmits it to the computer 17 inside the monitoring station 15. The computer 17 uses preset algorithms and models to perform in-depth processing and analysis on the received data. By comparing data such as pressure, strain, anchor bolt tension, and displacement with preset safety thresholds, it is determined whether the stress and deformation of the anchored piles are within normal limits. If all data are within the safety threshold range, the computer 17 displays the stress and deformation of the piles 4 in the form of charts and data lists on the display screen 16 for engineers to view and monitor the project status in real time. When any data exceeds the safety threshold, the computer 17 immediately sends a signal to the controller 19. Upon receiving the signal, the controller 19 triggers the alarm 20 to issue an audible and visual alarm, alerting on-site personnel. Simultaneously, it highlights the abnormal data on the display screen 16 so that engineers can take timely measures to prevent safety accidents caused by pile deformation.
