Description

TECHNICAL FIELD

[0002] The foundation pit slope refers to a rock-soil body with a specific inclination formed during the excavation of a foundation pit due to excavation work. When encountering changes in geological conditions, increased groundwater activity, increased external load, or other unfavorable factors, the stability of the foundation pit slope may be affected, leading to the overall or partial instability of the rock-soil body along a specific potential sliding surface or area, and ultimately may cause the rock-soil body to slide or collapse. To ensure engineering quality and construction safety, the stability of the foundation pit slope is usually monitored for slippage to achieve real-time early warning and risk control.

[0030] In one embodiment, for the above reinforcing assembly 7, the reinforcing assembly 7 comprises a fixed rod 701 arranged at the top end of the fixed groove 6, the bottom end of the fixed rod 701 is provided with a fixed disc 702, the bottom end of the fixed disc 702 is provided with a fixed column 703, the bottom end of the fixed column 703 is provided with a disc 704, the circumferential outer side of the fixed column 703 is provided with a gear one 705, and the gear one 705 is engaged with a gear two 706, the top end of the fixed disc 702 is provided with a driving motor three 707 connected with the gear two 706; the bottom end of the fixed disc 702 is provided with a plurality of limiting sliding grooves 708, the inside of the limiting sliding grooves 708 is provided with a sliding rod 709, one end of the sliding rod 709 is provided with a reinforcing drill bit 710 matched with the fixed hole 8; the top end of the gear one 705 is provided with a limiting hole 7051 matched with the sliding rod 709, thereby enhancing the connection strength between the monitoring device and the foundation pit slope, and effectively preventing the monitoring device from being displaced or tilted due to external factors.

[0031] The working principle of the reinforcing assembly 7 is as follows: the driving motor three 707 is started by the controller, so that the output shaft of the driving motor three 707 drives the gear two 706 to operate, and the gear one 705 is driven to operate under the meshing action of the gear two 706 and the gear one 705, so that the sliding rod 709 matched with the limiting hole 7051 moves, and then the reinforcing drill bit 710 moves, through the cooperation between the reinforcing drill bit 710 and the fixed hole 8, the reinforcing drill bit 710 is inserted into the hole groove of the foundation pit slope, the monitoring device and the slope surface of the foundation pit are reinforced, and the stability of the monitoring device is improved.

[0032] The working principle of the reinforcing assembly 7 is as follows: the driving motor one 304 is started by the controller, the output shaft of the driving motor one 304 drives the arc-shaped plate one 302 to rotate, so that the connecting rod one 305 located in the through hole one 303 moves left and right, and under the cooperation of the sliding limiting block one 306 and the sliding limiting block two 3074, the left and right adjustment of the horizontal assembly 4 is realized; the driving motor two 3011 is started by the controller, the output shaft of the driving motor two 3011 drives the arc-shaped plate two 309 to rotate, so that the connecting rod one 305 located in the through hole two 3010 moves forward and backward, and under the cooperation of the sliding limiting block one 306 and the sliding limiting block two 3074, the forward and backward adjustment of the horizontal assembly 4 is realized; by controlling the left and right and forward and backward movement of the horizontal assembly 4, multi-dimensional adjustment of the horizontal assembly 4 is realized, which flexibly adapts to the foundation pit slopes with different inclination angles.

[0033] It needs to be explained that when the deformation or displacement of the foundation pit slope occurs, the inclination angle of the slope changes, causing the upper surface of the bottom plate 1 to be no longer in a horizontal state; at this time, the rolling ball 402 located in the middle of the top end of the connecting plate 401 loses the original balance state due to the action of gravity and starts to roll in the new inclined direction. The rolling ball 402 will contact the surrounding alarm 404 during movement. Once the rolling ball 402 triggers the alarm, the alarm 404 will activate its internal switch or sensor, triggering an alarm signal. The alarm signal is transmitted to the controller through the built-in circuit or directly sends out a sound, light, etc. warning signal, reminding the staff to pay attention to the abnormal situation of the slope.

[0034] In order to facilitate the understanding of the above technical solutions of the utility model, the working principle or operation mode of the utility model in the actual process will be described in detail below.

[0035] In actual application, the monitoring device is placed on the foundation pit slope to be monitored. First, the fixed cone 5 is inserted into the drill hole previously opened on the slope surface of the foundation pit, and a plurality of hole grooves are opened on the inner wall of the drill hole (the drill hole and the hole groove are conventional technologies in the construction field, not shown in the figure). Then, the slope surface of the foundation pit is matched with the reinforcing assembly 7 (the working principle of the reinforcing assembly 7 is as described above) to ensure the stability of the monitoring device and prevent it from being affected by external factors. After the monitoring device is fixed, the adjusting assembly 3 is operated by the controller to adjust the horizontal assembly 4, so that the horizontal assembly 4 is in a horizontal state (the working principle of the reinforcing assembly 7 is as described above), thereby adapting to the foundation pit slope surface with different inclination angles. When the deformation or displacement of the foundation pit slope occurs, the inclination angle of the slope will also change, causing the upper surface of the bottom plate 1 to no longer remain in a horizontal state. At this time, the rolling ball 402 loses the imbalance and rolls around to touch the alarm 404, triggering the alarm 404 to send an alarm signal, timely reminding the staff to detect the foundation pit slope condition.

[0036] In summary, by means of the above technical solutions of the utility model, through the mutual cooperation of the protective shell 2 and the reinforcing assembly 7, the connection strength between the monitoring device and the foundation pit slope can be enhanced, effectively preventing the monitoring device from being displaced or inclined due to external factors, which helps to more accurately monitor the stability and safety of the foundation pit slope, providing reliable decision basis for engineering management personnel. By setting the adjusting assembly 3, flexible adjustment of the monitoring dimension is realized, so that various inclination angles of the foundation pit slope environment can be accurately adapted, not only widening the application range of the monitoring device, but also significantly improving the accuracy and efficiency of the monitoring work, ensuring the accuracy and reliability of the monitoring data.
