Description

Technical Field

[0001] The utility model relates to the technical field of slope monitoring equipment, in particular to a dynamic monitoring device for foundation pit slope stability. Background Art

[0002] The foundation pit is a pit excavated at the foundation design location according to the base elevation and foundation plane dimensions, and the gently descending slope of the pit is the side slope. The stability of the foundation pit is guaranteed by the slope support. Therefore, one of the important factors affecting the stability of the foundation pit is the stability of the side slope.

[0003] Traditional slope stability support usually involves laying a mesh concrete pavement on the slope to cover the slope. However, after a long time, the slope will inevitably settle and deform, and there is a risk of collapse. Therefore, real-time monitoring of the slope's stability is necessary. Traditional monitoring methods either set up monitoring or use electronic components to monitor the slope's surface status. However, these two methods cannot monitor changes in internal slope settlement. When the slope begins to settle, its surface may not necessarily change, which will affect the accuracy of slope stability monitoring.

[0004] To this end, the utility model provides a foundation pit slope stability dynamic monitoring device for real-time monitoring of slope settlement changes. Utility Model Content

[0008] The detection component includes a hollow anchor rod embedded in the slope, the free end of the anchor rod is penetrated by an anchor plate, the anchor plate is against the surface of the slope, the free end of the anchor rod is threaded with a self-locking nut and a fastening nut, a suspension is fixed on the fastening nut, a detection rail is fixed on the upper end of the suspension, a pointer is slidably installed on the detection rail along the length direction, a spring is provided between the pointer and the detection rail, a distance sensor cooperating with the pointer is provided at the end of the detection rail facing away from the anchor rod, the distance sensor is electrically connected to the monitoring component, a steel wire rope is fixed to the side of the pointer facing the anchor rod, and the end of the steel wire rope passes through the hollow part of the anchor rod and is fixedly connected to the anchor end of the anchor rod.

[0009] Preferably, the spring is always in a stretched state.

[0018] Compared with the existing technology, the present invention provides a dynamic monitoring device for foundation pit slope stability, which has the following beneficial effects:

[0019] 1. After the anchor rod is buried in the slope, it can not only reinforce the slope through the anchor rod and the anchor plate, but also play a role in contraction when the slope settles, thereby reducing the impact of the landslide. Moreover, when the slope just starts to settle, the anchor rod has stress crossover due to the length difference between the anchor end and the free end. When the slope settles to a certain extent, the anchor rod begins to bend and deform, thereby pulling the internal wire rope, and the wire rope will pull the pointer, causing the pointer to move in the direction away from the spacing sensor in the chute. When the distance between the pointer and the spacing sensor increases, a signal will be sent to the data collection module in real time. The data collection module will transmit the collected slope settlement information to the monitoring terminal at the base through the wireless transmission module. In this way, the settlement changes inside the slope can be remotely monitored, and the data can be transmitted in real time to produce a data model, which not only makes the monitoring information more accurate but also more intuitive.

[0020] 2. The monitoring component also includes a solar panel, which is electrically connected to a battery. The solar panel generates electricity for the electronic components, which is energy-saving and environmentally friendly.

[0021] 3. It also includes monitoring equipment, which is distributed on the slope and is used to observe and record the changes in slope surface settlement in real time. Combined with the monitoring components, it can monitor the settlement changes inside and outside the slope in real time, making the monitoring data more accurate.

[0022] 4. The detection rail is equipped with a scale that cooperates with the pointer. During daily patrol inspections, when inspectors pass by the monitoring components, they can also visually view the changes in slope settlement in this area from the scale, which is more flexible to use.

[0023] 5. Each set of detection components is equipped with a positioning module, which is electrically connected to the data collection module. When the data collection module receives the slope settlement information of the area, it can synchronously transmit the area position, realize the corresponding change data display of the area and settlement, and the monitor can also more intuitively see where the settlement area is located, and can also make adjustment measures more quickly.

[0024] Other advantages, objectives and features of the present invention will be described in the following description to some extent; and will be apparent to those skilled in the art based on an examination of the following; or may be taught from the practice of the present invention to some extent.

At the same time, when the slope settles, it can play a contraction role to reduce the impact of the landslide. Moreover, when the slope just starts to settle, the anchor rod 1 has stress staggered due to the length difference between the anchor end and the free end. When the slope settles to a certain extent, the anchor rod 1 begins to bend and deform, thereby pulling the internal wire rope 9, and the wire rope 9 will pull the pointer 5, causing the pointer 5 to move in the chute in the direction away from the spacing sensor 6.

[0040] In embodiment 4, a scale 8 cooperating with the pointer 5 is provided on the detection rail 4. During daily patrol inspections, when the inspector passes by the monitoring component, he can also visually view the slope settlement changes in this area from the scale 8, which is more flexible to use.

[0041] In Example 5, multiple groups of detection components are evenly distributed on the slope, and the multiple groups of detection components are electrically connected to the monitoring components. Multiple groups of anchor rods 1 are provided, and the anchor rods 1 are evenly distributed on the slope, that is, the slope is reinforced and monitored in sections, further improving the accuracy of the monitoring data.

[0042] In Example 6, each set of detection components is provided with a positioning module, and the positioning module is electrically connected to the data collection module, so that when the data collection module receives the slope settlement information of the area, it can synchronously transmit the area position, realize the corresponding change data display of the area and settlement, and the monitor can also more intuitively see where the settlement area is located, and can also make adjustment measures more quickly.

[0046] The second method is to install a screw on the side wall of the fixed box, and screw the screw so that the end of the screw is firmly pressed against the movable end of the wire rope 9, thereby forming a loop and buckling it on the guide wheel;

[0047] The third type: the movable end of the wire rope 9 passes through the fixed box and then goes around the guide wheel. Then the movable end of the wire rope 9 passes through the fixed box again. The movable end of the wire rope 9 is welded with a screw. After the screw passes through the fixed box, a nut is threadedly installed. The nut rests on the bottom wall of the fixed box, thereby forming a ring buckle and buckled on the guide wheel.
