Abstract
Description
Technical Field
[0001] This utility model relates to the field of slope protection technology, specifically to a bouncing passive protection net structure suitable for vertical slopes. Background Technology
[0002] Currently, various geological disasters occur frequently in China. For the management of landslides, rockfalls, and other geological disasters on slopes, passive protective nets are commonly used to intercept falling rocks and other debris to prevent and manage these disasters. However, current passive protective net systems have low buffering capacity and complex structures. After an impact, if the passive protective net system needs to be reused, it must be completely replaced. Furthermore, falling rocks and debris onto the passive protective net system are difficult to remove, especially on slopes with a near-vertical gradient, where personnel and equipment have limited access, further increasing the difficulty of removal and making it difficult to restart the passive protective net system. Utility Model Content
[0003] To address the aforementioned issues, this application provides a bouncing passive protective net structure suitable for vertical slopes, which can guide falling rocks and objects to a safe area, reduce the amount of falling rocks and objects remaining on the protective net structure, and eliminate the need for frequent cleaning of the protective net structure.
[0004] The objective of this utility model is achieved through the following technical solution: a bouncing passive protective net structure suitable for vertical slopes, comprising:
[0005] At least two steel columns are fixed to the slope.
[0006] The lower horizontal support rope is connected to the top of all steel columns;
[0007] The upper horizontal support rope is fixed to the slope above the steel column by several anchor rods;
[0008] A protective net is connected between a lower transverse support rope and an upper transverse support rope; the side of the protective net away from the slope is inclined downward so that an obtuse angle α is formed between the protective net and the slope above the upper transverse support rope.
[0009] This invention, by setting the protective net at an angle, allows falling rocks and debris on the slope to roll down along the net to a safe area, preventing them from remaining on the net and becoming difficult to clean. It is especially suitable for vertical slopes where personnel and equipment cannot reach.
[0010] Several longitudinal support ropes are connected between the lower and upper transverse support ropes, and the longitudinal support ropes support the protective net below.
[0011] The column head of the steel column is connected to the upper horizontal support rope by a diagonal support rope. The diagonal support rope extends along the diagonal of the protective net and is supported below the protective net.
[0012] The protective net is composed of several protective net units spliced together, and the longitudinal support rope is supported below the splice of two adjacent protective net units.
[0013] The support provided by the longitudinal and diagonal support ropes enables the protective net to withstand stronger impacts, thus improving the durability of this invention.
[0014] It also includes an upper pull rope; one end of the upper pull rope is connected to the column head of the steel column, and the other end is fixed to the slope above the steel column by an anchor rod.
[0015] With the help of the pull rope, the steel column can be installed more securely on the slope.
[0016] Energy-absorbing rings are provided on the upper pull rope, the upper transverse support rope, and / or the lower transverse support rope. The energy-absorbing rings improve the buffering performance of this invention, enabling it to withstand stronger impact forces.
[0017] The steel column is fixed to the slope by a base; the base is provided with lugs, and the steel column is swayably connected to the lugs by bolts.
[0018] The steel column of this invention can swing, thereby adjusting the angle between the steel column and the slope, and further adjusting the angle between the protective net and the slope, making this invention applicable to different slope terrains and improving its applicability.
[0019] The protective netting can be a ring net, diamond net, grid net, single twisted net, or double twisted hexagonal net.
[0020] Compared with the prior art, this application has the following beneficial effects: By setting the protective net at an angle, the falling rocks and objects on the slope can roll down the protective net to a safe area after falling on it, preventing the falling rocks and objects from staying on the protective net and being difficult to clean. It is especially suitable for vertical slopes where personnel and equipment cannot reach.

These additional features will become apparent to those skilled in the art upon examination of the following description and the accompanying drawings, or upon understanding the production or operation of the embodiments.

Detailed Implementation
[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.
[0028] Example
[0029] like Figure 1 , 2 As shown in the figure, this embodiment discloses a bouncing passive protective net structure suitable for vertical slopes, which includes: at least two steel columns 2, a lower horizontal support rope 7, an upper horizontal support rope 6, and a protective net 1.
[0030] In specific setup, the number of steel columns 2 can be determined according to the length of the slope to be protected. The longer the slope to be protected, the longer the protective net 1 needs to be, and the more steel columns 2 are needed.
[0031] The lower transverse support ropes 7 are connected in series and fixed to the column heads of all steel columns 2, that is, the column heads of all steel columns 2 are connected in series by the lower transverse support ropes 7. The upper transverse support ropes 6 are fixed to the slope above the steel columns 2 by several anchor rods 3.
[0032] One end of the protective net 1 is connected to the lower transverse support rope 7 via a shackle, and the other end is connected to the upper transverse support rope 6 via a shackle. Since the upper transverse support rope 6 is higher than the lower transverse support rope 7, the side of the protective net 1 furthest from the slope tilts downwards, thus forming an obtuse angle α between the protective net 1 and the slope above the upper transverse support rope 6. Specifically, the obtuse angle α can be set to 120°–160°; in this embodiment, it is set to 135°.
[0033] In specific installations, the length of the steel column 2 can be set according to the specific terrain, and its length must allow the lower end of the protective netting 1 to extend to a safe area. For example, when this embodiment is installed on a slope above a highway, the lower end of the protective netting 1 needs to extend to the outside of the highway, so that falling rocks and debris from the slope can roll down along the protective netting 1 to a safe area outside the highway. Figure 1 As shown.
[0034] In this embodiment, by setting the protective net 1 at an angle, rocks and objects falling from the slope onto the protective net 1 can roll down to a safe area, preventing them from remaining on the protective net 1 and becoming difficult to clean. This is especially suitable for vertical slopes where personnel and equipment cannot reach.
[0035] Among them, the protective net 1 can be one of the following: ring net, diamond net, grid net, single twisted net, and double twisted hexagonal net.
[0036] In addition, several longitudinal support ropes 8 are connected between the lower transverse support rope 7 and the upper transverse support rope 6, and the longitudinal support ropes 8 support the protective net 1 below. Specifically, the longitudinal support ropes 8 can be connected to the lower transverse support rope 7 and the upper transverse support rope 6 via shackles. The longitudinal support ropes 8 are spaced apart, and adjacent longitudinal support ropes 8 are parallel to each other. Through the support of the longitudinal support ropes 8, the protective net 1 can withstand stronger impact forces.
[0037] As another optional implementation of this embodiment, the column head of the steel column 2 is also connected to the upper transverse support rope 6 by a shackle with a diagonal support rope 9. The diagonal support rope 9 extends along the diagonal of the protective net 1 and is also supported below the protective net 1.
[0038] The support of the inclined support rope 9 further improves the impact resistance of the protective net 1, making this utility model more durable.
[0039] When the slope to be protected is long, the protective net 1 can be spliced together from several protective net units, that is, the protective net 2 is spliced together from multiple protective net units by shackles. At this time, the longitudinal support rope 8 mentioned above is supported below the splicing point of two adjacent protective net units to improve the strength of the splicing point.
[0040] In addition, the steel column 2 can also be secured using the pull rope 4. Specifically, one end of the pull rope 4 is connected to the head of the steel column 2 via a shackle, and the other end is fixed to the slope above the steel column 2 via an anchor rod 3. The pull of the pull rope 4 ensures that the steel column 2 is more firmly installed on the slope.
[0041] Furthermore, energy-absorbing rings 5 are provided on the upper pull rope 4, the upper horizontal support rope 6, and / or the lower horizontal support rope 7. The energy-absorbing rings 5 can absorb the impact force of falling rocks on the protective net 1, improve the buffering performance of this utility model, and enable this utility model to withstand stronger impact forces.
[0042] As another optional implementation of this embodiment, such as Figure 3 As shown, the steel column 2 is fixed to the slope by the base 10; the base 10 is provided with two lugs, and an installation cavity is formed between the two lugs. The installation end of the steel column 2 is installed in the installation cavity, and then the installation end of the steel column 2 is connected to the lugs by bolts, so that the steel column 2 can swing with the bolts as the fulcrum.
[0043] In this embodiment, the steel column 2 can swing, thereby adjusting the angle between the steel column 2 and the slope, and further adjusting the angle between the protective net 1 and the slope, making this utility model applicable to different slope terrains and improving its applicability.
[0044] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.
[0045] Furthermore, the specific embodiments described above are exemplary. Those skilled in the art can devise various solutions inspired by the disclosure of this utility model, and these solutions all fall within the scope of this utility model and its protection. Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims.
