Description

Technical Field

[0001] This application relates to the field of foundation pit monitoring technology, specifically to a monitoring box for deep foundation pit support piles. Background Technology

[0002] As a fundamental engineering project for underground structure construction, the construction safety of deep foundation pits is of paramount importance. With the continuous increase in the depth of the foundation pit, the risk of collapse increases exponentially. At the same time, the problem of anti-buoyancy of underground structures becomes increasingly prominent, especially in densely populated areas and riverside areas. Due to factors such as high lateral earth pressure, high soil moisture content, and frequent rainfall, the risk of foundation pit collapse is further increased. Therefore, the research and application of deep foundation pit deformation monitoring technology has become particularly important. Effective monitoring can not only provide early warning of potential risks and prevent problems before they occur, but also significantly reduce economic costs compared to post-disaster reconstruction after a collapse, achieve resource recycling, and effectively protect the lives and property of the people and construction workers.

[0003] Traditional foundation pit monitoring systems, such as the LRK IoT sensor foundation pit monitoring system, while possessing advantages like high precision and automated acquisition of deep horizontal displacement (inclinometer) data, and featuring functions like automatic calibration, initial zeroing, and real-time wireless transmission for real-time monitoring of foundation pit support, require numerous sophisticated sensors. This results in high equipment investment and production costs, and the system struggles to handle all support piles, exhibiting poor targeting and comprehensiveness. Furthermore, the need for power cables leads to clutter on-site, increases the risk of electrical leakage and short circuits, and hinders flexibility and convenience. Therefore, this foundation pit monitoring system requires further improvement. Additionally, there is currently a lack of dedicated deformation monitoring equipment for support piles on the market. Summary of the Invention

[0004] This application provides a monitoring box for deep foundation pit support piles, which has the advantages of high monitoring sensitivity and flexible and convenient use, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned objectives, this application provides the following technical solution:

[0006] This application provides a monitoring box for deep foundation pit support piles, comprising a box body, a mounting plate, and a target plate. A cantilever plate is fixedly installed on one side surface of the mounting plate, and the box body is connected to the top surface of the cantilever plate via a screw thread. A partition is fixedly installed inside the box body, and a signal transmitter and a battery are fixedly installed on the top surface of the partition. A first ball switch and a second ball switch are fixedly installed on the bottom surface of the partition. A displacement sensor is fixedly installed below the partition inside the box body. A vibration switch is fixedly installed on the inner wall of the box body. A top frame is fixedly installed on the top surface of the box body, and a photovoltaic panel is fixedly installed on the top surface of the top frame. The photovoltaic panel is connected to the battery, and the battery is connected to various electrical components and provides power. A mounting rod is fixedly installed on the bottom surface of the target plate, and the target plate is located directly below the displacement sensor.

[0007] Furthermore, multiple sets of the leveling screws are distributed at equal angles along the vertical center line of the box, and the leveling screws are used in conjunction with a circular level, which is installed on the top surface of the box.

[0008] Furthermore, the mounting plate has a through-threaded fixing screw connected to its surface, and the fixing screw is fixedly connected to the support pile.

[0009] Furthermore, the first ball switch and the second ball switch are arranged vertically, and both the first ball switch and the second ball switch are electrically connected to the signal transmitter.

[0010] Furthermore, the output terminal of the vibration switch is electrically connected to the signal transmitter.

[0011] Furthermore, the output terminal of the displacement sensor is electrically connected to the signal transmitter.

[0012] Furthermore, the bottom surface of the box and the surface of the cantilever plate are respectively provided with bottom holes and through holes, and the transmitter and receiver of the displacement sensor both pass through the bottom holes.

[0013] Furthermore, the target plate is installed directly below the through hole, and concentric rings of gradually darker color are printed on the surface of the target plate from the inside to the outside.

[0014] Furthermore, a protective sleeve is installed on the outside of the target plate.

[0015] Furthermore, a door is hinged to the front of the box, and an alarm is fixedly installed on one side of the box. The output terminals of the first ball switch, the second ball switch, the vibration switch, and the displacement sensor are synchronously and electrically connected to the alarm.

[0016] Compared with the prior art, the monitoring box for deep foundation pit support piles provided in this application has the following advantages:

[0017] (1) This application uses a vibration switch, a first ball switch, a second ball switch, a displacement sensor and a target plate. The box is installed on the surface of the support pile through the mounting plate. The first ball switch and the second ball switch are arranged vertically. When the support pile tilts, the first ball switch or the second ball switch is activated, triggering the signal transmitter to complete the signal transmission. The first ball switch and the second ball switch, which are arranged vertically to each other, monitor the tilt of the pile in two directions, improving the comprehensiveness of the monitoring. At the same time, the vibration switch is activated when the support pile vibrates, triggering the signal transmitter. When the support pile has a non-tilting displacement, a relative displacement is generated between the displacement sensor and the target plate. The displacement sensor is activated, triggering the signal transmitter to complete the signal transmission, thereby monitoring the support pile in all directions. The structure is simple, easy to use, and sensitive. The box is arranged correspondingly to the support pile, making the monitoring more comprehensive and significantly improving the efficiency of monitoring the deformation of the support pile and deep foundation pit.

[0018] (2) This application uses foot screws. Workers can fix the mounting plate to the support pile with the fixing screws. Then, the level of the box can be adjusted by foot screws to avoid the box tilting and causing the first ball switch and the second ball switch to malfunction. The foot screw adjustment method is the same as the level adjustment method. The level status can be determined by observing the circular level on the top surface of the box, which further improves the convenience of use and installation.

[0019] (3) This application uses photovoltaic panels and storage batteries. The photovoltaic panels are installed on the top of the box to generate electricity using sunlight. The electricity is stored in the storage batteries through the inverter and solar charger to power the signal transmitter and displacement sensor, eliminating the trouble of pulling wires and making it more flexible and convenient to use.

[0027] Please refer to Figure 1-5This application provides a monitoring box for deep foundation pit support piles, including a box body 1, a mounting plate 16, and a target plate 19. A cantilever plate 17 is fixedly installed on one side surface of the mounting plate 16. The cantilever plate 17 is arranged perpendicularly to the mounting plate 16, and the outline of the mounting plate 16 matches the support pile. The top surface of the cantilever plate 17 is connected to the box body 1 via a foot screw 14. The foot screw 14 is a common device, and its working principle and connection method will not be described in detail here. A partition 2 is fixedly installed inside the box body 1. A signal transmitter 3 and a battery 12 are fixedly installed on the top surface of the partition 2, and a first [missing information - likely a device name or component] is fixedly installed on the bottom surface of the partition 2. A ball switch 7 and a second ball switch 8 are installed inside the housing 1, below the partition 2. A displacement sensor 4 is fixedly installed inside the housing 1. A vibration switch 6 is fixedly installed on the inner wall of the housing 1. A top frame 10 is fixedly installed on the top surface of the housing 1, and a photovoltaic panel 11 connected to the battery 12 is fixedly installed on the top surface of the top frame 10. A mounting rod 20 is fixedly installed on the bottom surface of the target plate 19, and the target plate 19 is located directly below the displacement sensor 4. The housing 1 is mounted on the surface of the support pile via a mounting plate 16. The first ball switch 7 and the second ball switch 8 are arranged vertically. When the support pile tilts, the first ball switch 7... Alternatively, the second ball switch 8 can be activated, triggering the signal transmitter 3 to send a signal. The first ball switch 7 and the second ball switch 8, arranged perpendicularly to each other, monitor the inclination of the pile in two directions, improving the comprehensiveness of the monitoring. Simultaneously, the vibration switch 6 activates when the support pile vibrates, triggering the signal transmitter 3. When the support pile experiences non-tilting displacement, a relative displacement occurs between the displacement sensor 4 and the target plate 19. The displacement sensor 4 then activates, triggering the signal transmitter 3 to send a signal, thus enabling comprehensive monitoring of the support pile. The system is simple in structure, easy to use, and highly sensitive in monitoring. The box 1 is arranged to correspond to the support piles, making the monitoring more comprehensive and significantly improving the efficiency of monitoring the deformation of the support piles and deep foundation pits. At the same time, the photovoltaic panel 11 is installed on top of the box 1 to generate electricity using sunlight, and the electricity is stored in the battery 12 through the inverter and solar charger. The battery 12 is connected to various electrical devices (such as signal transmitter 3, displacement sensor 4, vibration switch 6, first ball switch 7, second ball switch 8 and alarm, etc.) to form a circuit, which powers the signal transmitter 3 and displacement sensor 4, eliminating the trouble of pulling wires and making it more flexible and convenient to use.

[0028] In one embodiment, three sets of leveling screws 14 are distributed at equal angles along the vertical centerline of the housing 1, and the leveling screws 14 are used in conjunction with a circular level 9, which is installed on the top surface of the housing 1. The operator can fix the mounting plate 16 to the support pile using fixing screws 18. Then, the level of the housing 1 can be adjusted by the leveling screws 14 to prevent the housing 1 from tilting and causing the first ball switch 7 and the second ball switch 8 to malfunction. The adjustment method of the leveling screws 14 is the same as that of the level. The level can be determined by observing the circular level 9 on the top surface of the housing 1, which further improves the convenience of use and installation.

[0029] In one embodiment, a fixing screw 18 is threaded through the surface of the mounting plate 16 and is fixedly connected to the support pile, which is a common installation structure.

[0030] In one embodiment, the first ball switch 7 and the second ball switch 8 are arranged vertically, and both the first ball switch 7 and the second ball switch 8 are electrically connected to the signal transmitter 3, thereby improving the comprehensiveness of monitoring.

[0031] In one embodiment, the output terminal of the vibration switch 6 is electrically connected to the signal transmitter 3, which is a common switch control structure.

[0032] In one embodiment, the output of the displacement sensor 4 is electrically connected to the signal transmitter 3, and the signal transmitter 3 is wirelessly connected to the monitoring equipment through the signal receiver. This is a common transceiver device and will not be described in detail here.

[0033] In one embodiment, the bottom surface of the box 1 and the surface of the cantilever plate 17 are respectively provided with a bottom hole 5 and a through hole 15. The transmitter and receiver of the displacement sensor 4 both pass through the bottom hole 5 to facilitate the operation of the displacement sensor 4.

[0034] In one embodiment, the target plate 19 is installed directly below the through hole 15, and the surface of the target plate 19 is printed with gradually darker colored rings from the inside to the outside. The change in color excites the displacement sensor 4, thereby improving the detection sensitivity.

[0035] In one embodiment, a protective sleeve 21 is installed on the outside of the target plate 19 to protect the target plate 19. The target plate 19 is inserted into the foundation through the mounting rod 20, and the protective sleeve 21 is inserted into the foundation together.

[0036] In one embodiment, a door 22 is hinged to the front of the box body 1, and an alarm 13 is fixedly installed on one side surface of the box body 1. The output terminals of the first ball switch 7, the second ball switch 8, the vibration switch 6, and the displacement sensor 4 are synchronously electrically connected to the alarm 13. When triggered, the alarm 13 emits an alarm sound to remind nearby staff to evacuate.
