[0001] This utility model relates to the field of deep foundation pit monitoring technology, and in particular to an adjustable T-shaped deep foundation pit monitoring device. Background Technology

[0002] With the continuous increase in urban population density and urban development in my country, the rational development and utilization of underground space is a requirement for sustainable urban development. Major cities in my country are building or preparing to build underground projects, which may involve deep foundation pit projects. The outstanding feature of deep foundation pit projects is that, in addition to ensuring the technical rationality and safety of the deep foundation pit project itself, its design and construction also need to control its environmental impact.

[0003] Traditional deep foundation pit monitoring devices typically have fixed angles or cumbersome angle adjustment methods, making them unable to quickly and accurately adapt to deep foundation pits of different shapes and different monitoring needs. Furthermore, their vertical adjustment capabilities are limited, making it difficult to flexibly adjust the height according to the different depths of the deep foundation pits. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable T-shaped deep foundation pit monitoring device.

[0008] Preferably, the sliding plate is a semi-circular straight plate with an arc-shaped groove. A slider is provided in the arc-shaped groove and is fixedly connected to a horizontal plate. One side of the slider extends to the center of the sliding plate, and a limiting rod passes through the center of the sliding plate, passing through the slider and the sliding plate.

[0009] Preferably, the limiting rod has an external thread on its body and a locking nut is threadedly connected to it, and an anti-slip pad is provided between the locking nut and the sliding plate.

[0010] Preferably, the upper and lower ends of the sliding plate are symmetrically provided with fixing blocks, and each fixing block is provided with bolt holes. The vertical plate is provided with a vertical sliding groove, and fixing holes are provided at equal intervals in the vertical sliding groove. Fixing bolts are provided in the bolt holes, and the ends of the fixing bolts are screwed into the fixing holes.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4 This utility model discloses an adjustable T-shaped deep foundation pit monitoring device, comprising a vertical plate 1, a horizontal plate 2 on one side of the vertical plate 1, a sliding plate 3 between the horizontal plate 2 and the vertical plate 1, the horizontal plate 2 being movably connected to the vertical plate 1 via the sliding plate 3, a warning light 4 mounted on the top of the vertical plate 1, a level 5 fixedly mounted on the surface of the horizontal plate 2, and flexible pressure mechanisms symmetrically arranged on the surface of the horizontal plate 2, with rolling grooves 6 formed on the sliding seats between the flexible pressure mechanisms. The vertical plate 1 provides the main support structure for the entire device, the horizontal plate 2 is used to install other components and perform monitoring operations, the sliding plate 3 allows the horizontal plate 2 to move relative to the vertical plate 1, enabling vertical adjustment and improving the adaptability of the device to deep foundation pits of different depths, the warning light 4 issuing an alarm when an abnormality is detected, and the level 5 helping to maintain the balance of the horizontal plate 2. To improve monitoring accuracy, a flexible pressure mechanism and a rolling groove 6 work together for pressure monitoring. The flexible pressure mechanism includes a fixed base, which is an inverted L-shaped protrusion. An inner groove is opened on the side of the fixed base, and a spring 7 is installed in the inner groove. One end of the spring 7 is fixed to a pressure plate 8. A thin film pressure sensor 9 is provided on the side of the pressure plate 8 away from the spring 7. The fixed base provides an installation position for the spring 7 and other components. When the spring 7 is subjected to pressure, it deforms and plays a buffering role. The pressure ball 10 transmits the pressure to the thin film pressure sensor 9. The thin film pressure sensor 9 can sensitively sense pressure changes and improve monitoring accuracy. The circuit of the thin film pressure sensor 9 is connected to the warning light 4. The pressure ball 10 is provided on the rolling groove 6. The pressure ball 10 rolls on the rolling groove 6. When it reaches the edge position and contacts the thin film pressure sensor 9, it can accurately trigger the warning and improve the timeliness of the warning.

[0020] In this invention, the sliding plate 3 is a semi-circular straight plate with an arc-shaped groove 11. A slider is installed within the arc-shaped groove 11 and is fixedly connected to the horizontal plate 2. One side of the slider extends to the center of the sliding plate 3, and a limiting rod passes through the center of the sliding plate 3, penetrating both the slider and the sliding plate 3. The semi-circular design of the sliding plate 3 and the arc-shaped groove 11 provide a basis for adjusting the angle of the horizontal plate 2. The slider slides within the arc-shaped groove 11, thereby adjusting the angle of the horizontal plate 2 and improving the adaptability of the device to deep pits of different shapes. The limiting rod restricts the position of the slider, ensuring the stability of the angle adjustment. The limiting rod has an external thread, and a locking nut is threaded onto it. An anti-slip pad is provided between the locking nut and the sliding plate 3. The positioning rod and locking nut work together to firmly lock the position of the limiting rod, thereby fixing the angle of the horizontal plate 2. The anti-slip pad increases the stability of the locking and prevents the angle from changing during use. The upper and lower ends of the sliding plate 3 are symmetrically provided with fixing blocks, and bolt holes are opened on the fixing blocks. The vertical plate 1 is provided with a vertical slide groove 12, and fixing holes are opened at equal intervals in the vertical slide groove 12. Fixing bolts are provided in the bolt holes, and the ends of the fixing bolts are screwed into the fixing holes. The sliding plate 3 is provided with scale markings on the side wall of the arc-shaped slide groove 11. The fixing blocks, bolt holes, vertical slide groove 12 and fixing bolts work together to realize the up and down adjustment and fixation of the sliding plate 3 on the vertical plate 1. The scale markings make it easy to accurately read the angle adjustment value of the horizontal plate 2, improving the monitoring accuracy and operability.

[0021] Working principle: When using this utility model, the vertical plate 1 is installed at a suitable position on the edge of the deep foundation pit. The horizontal plate 2 is connected to the vertical plate 1 by the sliding plate 3. The position of the sliding plate 3 on the vertical plate 1 is adjusted according to the depth of the deep foundation pit and the monitoring requirements. The angle of the horizontal plate 2 is adjusted by the sliding of the slider in the arc-shaped groove 11. The angle is fixed by the limit rod and the locking nut. When the soil or structure in the deep foundation pit tilts, the horizontal plate 2 also tilts. At this time, the pressure ball 10 starts to roll on the rolling groove 6 due to gravity. As the tilt angle of the horizontal plate 2 changes, the pressure ball 10 gradually rolls towards the edge of the rolling groove 6. When the pressure ball 10 rolls to contact the thin film pressure sensor 9, it triggers the thin film pressure sensor 9. After the thin film pressure sensor 9 is triggered by the pressure ball 10, it triggers the warning light 4 to sound an alarm, reminding the staff that there is an abnormal situation in the deep foundation pit.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
