[0021] To make the technical problems, technical solutions and advantages to be solved by the present utility model clearer, the following will be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without creative work belong to the protection scope of the present utility model. In addition, the technical features involved in different implementation manners of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a locking connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] Such as Figure 1As shown in the figure, an embodiment of the present utility model provides a slow landslide protection device for slopes, which includes a bottom plate 1 for overall support of the device, a vertical plate 2 for blocking the damage of slope landslides, a support plate 3 for supporting the vertical plate 2, and a connecting plate 4 that can connect multiple bottom plates 1. Among them, the bottom plate 1 and the vertical plate 2 are connected through a first mortise and tenon structure 5, the bottom plate 1 and the support plate 3 are connected through a second mortise and tenon structure 6, and the bottom plate 1 and the connecting plate 4 are connected through a third mortise and tenon structure 7. Based on the setting of the mortise and tenon structure, installation and disassembly can be conveniently carried out. Multiple threaded holes 8 are also provided on the connecting plate 4, and multiple connecting plates 4 are connected through the threaded holes and bolts, so that the part composed of the bottom plate, the vertical plate, and the support plate is horizontally connected as a whole to protect the slope, and can be connected according to the actual slope and landslide situation on site.

[0025] As a preferred implementation manner, in this embodiment, the bottom plate 1, the vertical plate 2, and the support plate 3 are made of polyamide material through a mold into a hollow structure, and the connecting plate 4 is made of polyamide material through a mold into a solid structure. Polyamide material has good tensile, bending, and impact resistance properties, and can effectively resist landslide disasters while ensuring a small weight.

[0026] As a preferred implementation manner, in this embodiment, multiple mortise grooves are provided on the bottom plate 1, and tenons corresponding to the mortise grooves are provided on the vertical plate 2, the support plate 3, and the connecting plate 4. The cooperation of the tenons and the mortise grooves enables the vertical plate 2, the support plate 3, and the connecting plate 4 to form a stable connection with the bottom plate 1, and at the same time facilitates the installation of the vertical plate 2, the support plate 3, and the connecting plate 4 after the bottom plate 1 is laid flat.

[0027] As a preferred implementation manner, in this embodiment, multiple support plates 3 connected to the same bottom plate 1 are provided, and their cross-sections are all triangular to form a stable support for the vertical plate 2, and can maintain a high strength when blocking and resisting the landslide body 9 and will not fail. The inner side surface of the vertical plate 2 serves as the direct stress surface. When a landslide occurs on the slope, when the landslide body 9 slides to the device, the vertical plate 2 blocks the landslide body 9 to prevent it from rushing to buildings such as roads and civilian houses, and can also prevent secondary landslides, effectively protecting lives and avoiding economic losses.

[0028] It should be noted that in this embodiment, the connecting plate 4 and the bottom plate 1 both extend to the inner side of the vertical plate 2. When the vertical plate 2 blocks the landslide body 9, the bottom plate 1 will also be subjected to the pressure of the landslide body 9. Therefore, the overall device can be further stabilized and the resistance ability can be improved. Conduct a physical analysis of the device under ideal conditions. Assume that the total mass of the landslide body 9 is M, the weight of the landslide body 9 located above the device is m1, the total weight of the device (including objects such as sandbags or other fixing devices) is m2, the ground friction is μ, and the overall acceleration of the landslide body 9 is a. When the condition is met, the device will move, and the calculation formula is as follows:

[0029] Ma > μ(m1 + m2)g

[0030] Therefore, the resistance of the device (an object containing sandbags or other fixing devices) can be initially calculated.

[0031] As a preferred embodiment, in this embodiment, the thickness of the bottom plate 1 is 0.2 m, the length is 4 m, and the width is 4 m; the cross-section of the bottom plate 1 is set as a right trapezoid, with a slope on the side close to the landslide body 9, which can guide the landslide body 9. The upper base is 3.2 m, and the lower base is 4 m. The thickness of the vertical plate 2 is 0.2 m, the length is 4 m, and the height is 2.1 m. The length of the bottom right-angled side of the support plate 3 is 1 m, and the length of the other right-angled side is 2 m. The thickness of the connecting plate 4 is 0.1 m, the length is 2 m, and the height is 0.2 m. Of course, the dimensions can also be adjusted to be applied to multiple scenarios. The use of the device in two scenarios is described below.

[0032] Scenario 1: When the monitoring system alarms or it is predicted through data analysis that there may be a landslide danger on the slope in the future, this device can be used for prevention. The specific steps are as follows:

[0033] Step 1: Determine the number of devices and sandbags required by referring to the on-site survey data, calculations, and predicting the danger level of the slope.

[0034] Step 2: Transport the required devices and sandbags to the slope by freight truck.

[0035] Step 3: The construction workers assemble the devices according to the steps and arrange them at the locations where landslides may occur.

[0036] Step 4: Place the sandbags on the bottom plate to prevent the device from moving.

[0037] Step 5: The construction workers and transport vehicles withdraw.

[0038] Scenario 2: When disasters such as slow landslides occur on the slope in extreme weather conditions such as heavy rainfall and typhoons, this device can be used for blocking. The specific steps are as follows:

[0039] Step 1: Determine the number of devices and sandbags required by on-site survey, calculation, etc.

[0040] Step 2: Transport the required devices and sandbags to the landslide area of the slope by freight truck.

[0041] Step 3: The construction workers assemble the devices according to the steps and arrange them at the landslide location and the locations where landslides may occur.

[0042] Step 4: Push the device into the landslide by large machinery to protect key roads or buildings such as blocked roads and railways.

[0043] Step 5, the construction workers, transport vehicles and large machinery are withdrawn.

[0044] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0045] The above embodiments only express several implementation manners of the present application, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
