Description

Technical Field

[0001] The present application relates to the technical field of foundation pit monitoring, and specifically to a monitoring box for deep foundation pit support piles. Background Art

[0002] As the foundation project for underground structure construction, the construction safety of deep foundation pits is of vital importance. As the depth of the foundation pit continues to increase, the risk of collapse increases exponentially. At the same time, the anti-floating problem of the underground structure becomes more and more prominent, especially in areas with densely populated surrounding buildings and riverside areas. Due to factors such as large lateral earth pressure, high internal soil moisture content, and frequent rainy weather, 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 them before they happen, but also significantly reduce economic costs compared to post-disaster reconstruction after collapse, realize the recycling of resources, 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, offer the advantages of high precision and automated acquisition of deep horizontal displacement (inclinometer) data. The inclinometer also features automatic calibration, initial zeroing, and real-time wireless transmission, enabling real-time monitoring of foundation pit support conditions. However, these systems require a large number of sophisticated sensors, resulting in high equipment investment and production costs. Furthermore, they struggle to cover all support piles, resulting in limited targeting and comprehensiveness. Furthermore, they require power cords, which clutter the site, creating the risk of leakage and short circuits, and making them inflexible and inconvenient to use. Therefore, this foundation pit monitoring system could be further improved. Furthermore, there is currently a lack of specialized deformation monitoring equipment for support piles on the market. Summary of the Invention

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

[0005] In order to achieve the above application objectives, this application provides the following technical solutions:

[0006] The present application provides a monitoring box for deep foundation pit support piles, which includes a box body, a mounting plate and a target plate. A lifting plate is fixedly mounted on one side surface of the mounting plate, and the top surface of the lifting plate is connected to the box body through a foot screw. A partition is fixedly mounted inside the box body, a signal transmitter and a battery are fixedly mounted on the top surface of the partition, a first ball switch and a second ball switch are fixedly mounted on the bottom surface of the partition, a displacement sensor is fixedly mounted inside the box body below the partition, a vibration switch is fixedly mounted on the inner wall of the box body, a top frame is fixedly mounted on the top surface of the box body, a photovoltaic panel is fixedly mounted on the top surface of the top frame, the photovoltaic panel is connected to the battery, the battery is connected to various electrical devices and provides power supply, a mounting rod is fixedly mounted on the bottom surface of the target plate, and the target plate is located directly below the displacement sensor.

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

[0008] Furthermore, a fixing screw is threadedly connected through the surface of the mounting plate, and the fixing screw is fixedly connected to the supporting 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 vibration switch output end is electrically connected to a signal transmitter.

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

[0012] Furthermore, a bottom hole and a through hole are correspondingly opened on the bottom surface of the box body and the surface of the lifting plate, and the transmitting end and the receiving end of the displacement sensor both pass through the bottom hole.

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

[0014] Furthermore, a protective tube is installed on the outer side of the target plate.

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

[0016] Compared with the existing technology, the monitoring box for deep foundation pit support piles provided by this application has the following beneficial effects:

[0017] (1) This application adopts a vibration switch, a first ball switch, a second ball switch, a displacement sensor and a target plate. The box body 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 arranged vertically to each other monitor the tilt of the pile body in two directions, thereby 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 generates a non-tilting displacement, a relative displacement occurs between the displacement sensor and the target plate, the displacement sensor is activated, triggering the signal transmitter, completing the signal transmission, and then performing all-round monitoring of the support pile. The structure is simple, easy to use, and the monitoring is sensitive. The box body is arranged corresponding to the support pile, and the monitoring is more comprehensive, which significantly improves the efficiency of monitoring the deformation of the support pile and the deep foundation pit.

[0018] (2) This application uses foot screws. Workers can fix the mounting plate to the support piles through fixing screws. Then, the levelness of the box body can be adjusted through the foot screws to avoid the box body 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 horizontal state can be determined by observing the circular level on the top surface of the box body, which further improves the convenience of use and installation.

[0019] (3) This application uses photovoltaic panels and batteries. The photovoltaic panels are installed above the box body, use sunlight to generate electricity, and store the electricity in the battery 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.
