Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a monitoring device for foundation pit slope support engineering. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plan dimensions. Before excavation, an excavation plan should be determined based on geological and hydrological data and the condition of nearby buildings, and waterproofing and drainage work should be carried out. For shallow excavations, slope protection can be used to stabilize the soil slope, and the slope should be determined according to relevant construction regulations. For deeper excavations or those near buildings, excavation pit wall support methods, shotcrete wall protection methods, and even methods such as diaphragm walls and interlocking column-type bored piles can be used to prevent the outer soil layer from collapsing. For excavations without the influence of nearby buildings, the wellpoint method can be used to lower the groundwater level, and open excavation with slope protection can be adopted. In cold regions, natural freezing methods can be used for excavation, etc.

[0003] In existing foundation pit engineering, real-time monitoring of the pit slope is necessary to prevent slope collapse. Slope crack monitoring is a crucial aspect of this monitoring. Traditional slope crack monitoring requires periodic measurements using specialized equipment, which not only makes it difficult to detect which side of the slope is moving, but also necessitates manual alarms to alert personnel when abnormal crack measurements are detected. This process is cumbersome, time-consuming, and labor-intensive. Therefore, we propose a monitoring device for foundation pit slope support engineering. Utility Model Content

This not only makes it difficult to detect which side of the slope is moving, but also requires manual alarms to remind people when the crack measurement is abnormal. This is not only troublesome to operate, but also time-consuming and labor-intensive.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A positive electrode plate 20 is installed on the outer wall of the vertical plate 18, and a negative electrode plate 21 is installed on the outer wall of the sliding plate 16. The positive electrode plate 20, the negative electrode plate 21, the battery 11, and the alarm 10 are all connected by wires. In use, the two sets of fixing posts 1 are fixed on both sides of the crack. When the crack expands, the ground on both sides of the crack moves, which will drive the fixing posts 1 to move. In turn, the connecting plate 17 will move through the guide rod 8, which will drive the sliding plate 16 to move on the connecting rod 15. People can understand the degree of crack expansion by periodically observing the scale reading on the connecting plate 17. As the crack expands, the negative electrode plate 21 will move towards the positive electrode plate 20. When the crack expands to a certain extent, the negative electrode plate 21 will contact the positive electrode plate 20. At this time, a circuit is formed, the alarm 10 is powered on, and an alarm is sounded to remind people.

[0027] This utility model discloses a monitoring device for foundation pit slope support engineering. A rotating rod 4 is fixedly connected to the outer wall of the threaded ring 3. The rotating rod 4 and the threaded ring 3 are integrated. A rubber sleeve is nested on the rotating rod 4, which allows the operator to manually rotate the threaded ring 3, thus improving the ease of operation.

[0028] This utility model discloses a monitoring device for foundation pit slope support engineering. The screw 2 is connected to the rotating end of the rotating seat 5, and the connecting seat 6 is connected to the fixed end of the rotating seat 5. This can prevent the connecting seat 6 from rotating along with the screw 2, thus affecting the performance.

A limiting groove 26 is provided on the inner wall of the guide groove 22, and a limiting block 27 is fixedly connected to the outer wall of the locking block 24. The locking block 24 is connected to the limiting groove 26 through the limiting block 27, which can limit the locking block 24 and prevent the locking block 24 from falling out of the guide groove 22, thus affecting the use effect.

[0031] In use, first adjust the overall height according to the environment. During adjustment, rotate the rotating rod 4 to rotate the threaded ring 3. Since the screw 2 and the threaded ring 3 are threadedly connected, the screw 2 can be raised or lowered to adjust the height. After height adjustment, fix the fixing column 1 on both sides of the crack. After installation, press the locking block 24 inward. The locking block 24 retracts into the guide groove 22. At this time, the guide rod 8 loses its limiting effect with the fixing rod 7, and the guide rod 8 can be moved until it is in the appropriate position, aligning the positioning pin 12 with the crack. At this point, the device is complete. It can be used normally. When the crack expands, the ground on both sides of the crack moves, which will drive the fixed column 1 to move. In turn, it will drive the connecting plate 17 to move through the guide rod 8, which will drive the sliding plate 16 to move on the connecting rod 15. People can understand the degree of crack expansion by periodically observing the scale reading on the connecting plate 17. As the crack expands, the negative electrode plate 21 will move towards the positive electrode plate 20. When the crack expands to a certain extent, the negative electrode plate 21 will contact the positive electrode plate 20. At this time, a circuit is formed, the alarm 10 is powered on, and an alarm is sounded to remind people.
