Description

Technical Field

[0001] The utility model relates to the technical field of slope monitoring, and specifically provides a retaining wall deformation monitoring device. Background Art

[0002] Retaining walls are generally set up on the surface of the slope to stabilize the engineering structure of the slope. They are generally divided into gravity retaining walls, buttress retaining walls, cantilever retaining walls, plate-rib or lattice anchor retaining walls, etc. This engineering structure is widely used in roads, railways, construction sites, riverbanks and other places where soil stabilization is required to prevent soil landslides, soil erosion or other soil instability caused by gravity or water pressure. Nowadays, in order to ensure the safety of retaining wall structures, monitoring devices are set up to monitor the deformation of the slope and other safety levels.

[0003] Existing retaining wall monitoring devices can only monitor specific retaining walls. For example, Chinese patent CN114575394B discloses a device for monitoring stress and deformation of slope support, including several groups of installation components, which are respectively installed on the outer periphery of a reinforced concrete frame, and elastic parts are installed on the several groups of installation components, and tension sensors are installed on the several elastic parts. Several groups of monitoring line groups are installed on the reinforced concrete frame, and the several groups of monitoring line groups are fixedly connected to the tension sensors, and the tension sensors are connected to a control center.

[0004] This device is generally used for lattice anchor retaining walls, and determines the slope condition by monitoring the stress deformation of the exposed concrete frame. However, for gravity-type, buttress-type retaining wall structures with flat surfaces, no concrete frame or concrete frame that is not exposed, there is a lack of an efficient device for monitoring the retaining wall. Utility Model Content

[0005] The utility model provides a retaining wall deformation monitoring device, which can be used for real-time monitoring of the deformation of the retaining wall.

[0006] The technical solution of the utility model is as follows:

[0007] A retaining wall deformation monitoring device includes multiple groups of fence units, wherein the fence units include control rods and terminal rods, wherein the control rods and the terminal rods are fixedly arranged on the retaining wall through positioning units, and a taut steel wire rope is arranged between the control rods and the terminal rods. The fence units are electrically connected to a solar terminal part, and the solar terminal part is arranged on the top of the retaining wall. A tension sub-controller unit is arranged in the solar terminal part, and the solar terminal part is connected to a cloud platform through a network.

[0008] In this scheme, each group of fence units is responsible for monitoring a certain area of ​​the retaining wall. As long as the retaining wall is deformed, the position of the control rod and the terminal rod changes slightly, and the wire rope set between the control rod and the terminal rod will be lengthened or shortened. The control rod is a tension control rod, which can transmit the change of the tension strength of the wire rope hung on it to the tension sub-controller unit for processing, and upload the data to the cloud platform, so that the supervisor can obtain the data of the retaining wall in real time. When the tension strength change of the wire rope is greater than the set threshold, the tension sub-controller unit will issue an alarm and send an alarm message to the cloud platform. The retaining wall is monitored by multiple fence units separately, which can quickly locate the position of the deformed retaining wall, which is conducive to the subsequent inspection and maintenance of the retaining wall.

[0009] Preferably, the length directions of the control rod and the terminal rod are parallel to the surface of the retaining wall, and a plurality of groups of steel wire ropes are arranged at equal intervals between the control rod and the terminal rod.

[0010] In this solution, the control rod and the terminal rod are arranged on the surface of the retaining wall, and the rod is provided with a plurality of steel wire ropes as a whole, which improves the monitoring range and can also measure the relative displacement of the monitoring point according to the tension change between each section of the steel wire rope.

[0011] Preferably, the fence unit also includes a wire hanging rod, which is arranged between the control rod and the terminal rod, and both ends of the wire hanging rod are fixed on the retaining wall through the positioning unit. A guide roller is arranged in the middle of the wire hanging rod, and the wire rope passes through the guide roller.

[0012] In this scheme, a wire hanging rod is set every 10m in each group of fence units to support and guide the wire rope, preventing the gravity of the wire rope from affecting its tension, while also being able to adapt to the curved retaining wall surface.

[0013] Preferably, the middle portion of the wire hanging rod protrudes toward the outside of the retaining wall, and forms a rectangle with the surface of the retaining wall, and the guide roller is arranged in the rectangle.

[0014] In this solution, by setting the guide roller as mentioned above, the wheel wire rope is made as close to the surface of the retaining wall as possible. When the retaining wall is deformed and convex, and the wire rope contacts the surface of the retaining wall, the tension of the wire rope will change, thereby improving the monitoring accuracy and the actual monitoring effective area.

[0015] Preferably, the fence units are staggeredly arranged on the retaining wall.

[0016] In this scheme, the fence units are divided into horizontal and vertical arrangements relative to the surface of the retaining wall. The staggered arrangement of the fence units further increases the effective monitoring area. At the same time, the fence units are arranged vertically, and their control rods and terminal rods are respectively fixed at the top and bottom of the retaining wall. The tightened steel wire ropes can also provide certain protection for the retaining wall.

[0017] Preferably, the fence unit is provided with an inclination sensor electrically connected to the solar terminal part. The inclination change of the retaining wall surface is monitored by the inclination change of the rod in the fence unit. At the same time, combined with the tension change of the wire rope, the posture inclination state of the rod itself in the X, Y and Z directions can be determined, and the deformation displacement amount can be measured.

[0018] Preferably, the positioning unit comprises a fixing buckle and a positioning block, and the fixing buckle is a half-hoop type, clamping the rod structure of the fence unit on the retaining wall.

[0019] Preferably, the positioning block is provided with a groove, the positioning block is fixedly arranged on the retaining wall, and both ends of the rod structure of the fence unit are inserted into the groove, which can effectively prevent displacement between the rod and the positioning unit over a long period of time.

[0020] Preferably, an observation reference point is provided in the fence unit, and a visual monitoring unit is provided on the opposite side of the retaining wall.

[0021] In this solution, the visual monitoring unit performs image recognition on the wall slope, and through observing the position changes of reference points and background difference calculations, it analyzes and judges the changes in real time, and uses big data algorithm models to identify disasters and alarm on the slope.

[0022] Beneficial effects of the utility model:

[0023] The utility model has a simple structure and is easy to install. It can monitor most retaining walls, wherein each group of fence units is responsible for monitoring a certain area of ​​the retaining wall. As long as the retaining wall is deformed, the positions of the control rod and the terminal rod are slightly changed, and the steel wire rope set between the control rod and the terminal rod will be lengthened or shortened. The control rod transmits the change in the tension strength of the steel wire rope it hangs to the tension sub-controller unit for processing, and uploads the data to the cloud platform, so that the supervisor can obtain the data of the retaining wall in real time. When the change in the tension strength of the steel wire rope is greater than the set threshold, the tension sub-controller unit issues an alarm and sends an alarm message to the cloud platform. The retaining wall is monitored separately by multiple fence units, and the position of the deformed retaining wall can be quickly located, which is beneficial to the subsequent inspection and maintenance of the retaining wall.

[0034] In conjunction with the accompanying drawings, the technical solution of the present invention is clearly and completely described through the specific implementation methods of the embodiments of the present invention.

[0035] like Figure 1 and Figure 2 A retaining wall 5 slope deformation monitoring device is shown, comprising a plurality of fence units 1, wherein the fence units 1 comprise control rods 11 and terminal rods 12, wherein the control rods 11 and the terminal rods 12 are fixedly arranged on the retaining wall 5 of the slope of the retaining wall 5 via a positioning unit 2, wherein a taut steel wire rope 13 is arranged between the control rods 11 and the terminal rods 12, wherein the fence units 1 are electrically connected to a solar terminal part 3, wherein the solar terminal part 3 is arranged at the top of the slope of the retaining wall 5, wherein a tension sub-controller unit is arranged in the solar terminal part 3, and the solar terminal part 3 is connected to a cloud platform via a network.

[0036] Specifically, the control rod 11 is a tension control rod 11, which is a prior art and can sense the tension of the steel wire rope 13 arranged thereon and transmit the tension to the tension sub-controller through an electrical signal. Figure 6As described, the tension controller in this embodiment has two structures, a is a single-defense control rod 11, and b is a double-defense control rod 11, which are selected and arranged according to the on-site conditions. As long as the retaining wall 5 is deformed, the positions of the control rod 11 and the terminal rod 12 are slightly changed, and the wire rope 13 set between the control rod 11 and the terminal rod 12 will be lengthened or shortened, and the change in the tension strength of the hanging wire rope 13 can be transmitted to the tension sub-controller unit for processing, and the data is uploaded to the cloud platform, so that the supervisor can obtain the data of the retaining wall in real time. At the same time, the control rod 11 can ensure a static tension value of 50N-450N, avoiding animals or small stones from accidentally touching the wire rope 13 and causing false alarms, and the tension alarm threshold of the control rod 11: 5N-50N, or when the spacing between adjacent wire ropes 13 reaches 30mm, an alarm signal is issued, which fully meets the daily monitoring of the retaining wall 5.

[0037] like Figure 7 As shown, a circumferential groove is provided on the terminal rod 12. Since the wire rope 13 is generally sleeved on the terminal rod 12, the circumferential groove can effectively position the wire rope 13 on the terminal rod 12 to prevent the wire rope 13 from sliding when the tension of the wire rope 13 is insufficient.

[0038] At the same time, the solar terminal part 3 arranges a PVC pipe 31 and connects wires in the PVC pipe 31 so that the control rod 11 of each fence unit 1 can be connected to the solar terminal part 3.

[0039] It should be noted that since the power required to monitor the tension of the wire rope 13 is very small, a lithium battery can be built into each pole and a small solar panel can be set up to power itself. There is no need to specially set up a unified solar terminal 3. At this time, other devices such as the tension sub-controller unit can be set in a position that is convenient for operation according to actual conditions.

[0040] like Figure 3 The positioning unit 2 includes a fixing buckle 21 and a positioning block 22. The fixing buckle 21 is a half-hoop type, which clamps the rod structure of the fence unit 1 on the retaining wall 5. The positioning block 22 is provided with a groove, and the positioning block 22 is fixedly arranged on the retaining wall 5, and the two ends of the rod structure of the fence unit 1 are inserted into the groove. It can effectively prevent the displacement between the rod and the positioning unit 2 over a long period of time.

[0041] The steel wire rope 13 is preferably made of stainless steel SUS304 with a multi-strand structure, and is rust-proof and corrosion-resistant.

[0042] Embodiment 1:

[0043] The length direction of the control rod 11 and the terminal rod 12 is parallel to the surface of the retaining wall 5, that is, the length direction of each rod in the fence unit 1 is perpendicular to the length direction of the retaining wall 5, the direction of the steel wire 13 is the same as the length direction of the retaining wall 5, and the control rod 11 and the terminal rod 12 are arranged on the surface of the retaining wall 5. Multiple groups of steel wires 13 are arranged at equal intervals between the control rod 11 and the terminal rod 12, and multiple steel wires 13 are arranged on the entire rod.

[0044] In this embodiment, the rod is provided with a plurality of steel wire ropes 13, which improves the monitoring range and can also monitor the posture inclination of the rod in the X, Y, and Z directions in real time according to the tension changes between each section of the steel wire rope 13, in conjunction with the inclination sensor, and then measure the relative displacement of the monitoring point.

[0045] Each group of fence units 1 is responsible for monitoring a certain area of ​​the retaining wall 5. When the tension strength change of the wire rope 13 is greater than the set threshold, the tension sub-controller unit sounds an alarm and sends an alarm message to the cloud platform. The retaining wall 5 is monitored by multiple fence units 1 respectively, and the position of the deformed retaining wall 5 can be quickly located, which is beneficial to the subsequent inspection and maintenance of the retaining wall 5.

[0046] Further, such as Figures 3 to 5 As shown, the fence unit 1 also includes a wire hanging rod 14, and a wire hanging rod 14 is arranged every 10m between the control rod 11 and the terminal rod 12, and the wire hanging rod 14 is arranged between the control rod 11 and the terminal rod 12. Both ends of the wire hanging rod 14 are fixed on the retaining wall 5 through the positioning unit 2. A guide roller 15 is arranged in the middle of the wire hanging rod 14, and the wire rope 13 passes through the guide roller 15. The wire hanging rod 14 supports and guides the wire rope 13 to prevent the gravity of the wire rope 13 itself from affecting its tension.

[0047] Specifically, the middle part of the wire hanging rod 14 protrudes toward the outside of the retaining wall 5, and forms a rectangle with the surface of the retaining wall 5, and the guide roller 15 is arranged in the rectangle. The roller 152 structure includes a frame 151 fixedly set on the wire hanging rod 14, and two rollers 152 are rotatably arranged in the frame 151, and the wire rope 13 passes in front of the two rollers 152. The wire rope 13 is supported by the rollers 152. When the wall surface of the retaining wall 5 has an arc or a corner, the wire rope 13 does not lose tension, thereby ensuring the accuracy of the tension monitoring by the control rod 11. At the same time, the wire rope 13 is also made as close to the surface of the retaining wall 5 as possible. When the retaining wall 5 is deformed and protrudes, and contacts the wire rope 13 on the surface of the retaining wall 5, the tension of the wire rope 13 will change, thereby improving the accuracy of monitoring and the effective area of ​​actual monitoring.

[0048] Furthermore, when the terrain is "V"-shaped and retaining wall 5 slope structures are set on both sides of the road, a visual monitoring unit 4 can be set on the retaining wall 5, and an observation reference point can be set in the fence unit 1 of the retaining wall 5 on the opposite side. The visual monitoring unit 4 performs image recognition on the wall slope, and analyzes and judges the changes in real time through the position changes of the observation reference points and background difference calculations, and performs disaster identification and alarm on the slope through the big data algorithm model.

[0049] It should be noted that when the retaining wall 5 is provided on only one side, a visual monitoring unit 4 with built-in solar power generation can be provided at any symmetrical position of the retaining wall, preferably at a high position, to perform retaining wall image recognition.

[0050] Embodiment 2:

[0051] On the basis of implementing column 1, Figure 1 The fence units 1 are arranged in a staggered manner on the retaining wall 5 .

[0052] The length direction of the steel wire rope 13 of the fence unit 1 in Example 1 is the same as the length direction of the retaining wall 5. In this embodiment, the fence unit 1 arranged perpendicular to each other in Example 1, its control rod 11 and terminal rod 12 are respectively fixed at the top and bottom of the retaining wall 5, and its tightened steel wire rope 13 can also play a certain protective role on the slope of the retaining wall 5.

[0053] It should be noted that the grass-covered area of ​​the retaining wall 5 is a weak area, and the fence units 1 are arranged more densely to improve the protection capability of the retaining wall 5 .

[0054] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
