Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, and in particular to a slope riprap protection structure. Background Technology

[0002] With the continuous increase in infrastructure construction projects in forest areas such as transportation, energy, water conservancy, agriculture, forestry, and mining, the hazards of falling rocks caused by engineering operations such as slope blasting and high embankment construction are becoming increasingly serious. Therefore, during the construction period at the bottom of the slope, it is necessary to set up corresponding slope rockfall protection structures on the slope.

[0003] Currently, most methods of protecting against falling rocks include vertical interception ditches, slag barriers, and soil bags. These structural forms are not very effective in protecting against falling rocks on slopes, and it is inconvenient to dismantle and restore the relevant structures after the project is completed. In addition, it is impossible to obtain materials locally, which means that the trees that have been felled within the land acquisition area have not been effectively utilized. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a slope riprap protection structure to address the above-mentioned problems.

[0005] The technical solution adopted in this utility model is: a slope riprap protection structure, comprising:

[0006] Multiple retaining walls are set among native trees on the slope, and the multiple retaining walls are arranged in an array along the vertical direction;

[0007] The hoop assembly includes a first hoop and a second hoop, which are rotatably connected by a rotating assembly. The first hoop is used to encircle and fix the native trees, and the second hoop is used to connect and fix the ends of the fence posts, so that multiple fence posts between the native trees form a protective structure.

[0008] Using the above-mentioned technical means, the first hoop is used to fix the native trees on the slope, and the second hoop is used to fix the retaining rods. This allows the native trees on the slope to form a protective structure through multiple retaining rods, which can protect and intercept rolling stones on the slope. Furthermore, by using the native trees on the slope as fixing piles, the growth of the native trees can be maintained even after the hoop assembly is disassembled.

[0009] In some embodiments, the first hoop and the second hoop are both detachably assembled. The first hoop and the second hoop each include a thin plate, a pin, and a locking member. A plurality of arc-shaped thin plates are connected by the pin, and the opening and closing port formed by the connection of the plurality of thin plates is closed and fixed by the locking member.

[0010] In some embodiments, the number of the sheet and the pin is determined based on the diameter of the native tree and the diameter of the fence post. The circumference of the first hoop and the second hoop is adjusted by increasing or decreasing the number of the sheet and the pin, so that the first hoop is adapted to the diameter of the native tree and the second hoop is adapted to the diameter of the fence post.

[0011] In some embodiments, the locking member is a rotating bolt and a lock nut. One end of the first hoop and the second hoop are provided with guide grooves that can be adapted to the lock nut. The other end of the first hoop and the second hoop are rotatably connected to the rotating bolt via a rotating shaft. The shank end of the rotating bolt is rotated into the guide groove by the lock nut for fixing.

[0012] In some embodiments, the locking member further includes an anti-twist pin and a fixing rubber. The anti-loosening nut is provided with a pair of insertion holes. The opening and closing ports of the first hoop and the second hoop are provided with through holes corresponding to the insertion holes, so that the anti-twist pin can pass through the insertion holes and the through holes to restrict the rotation of the anti-loosening nut. The end of the anti-twist pin away from the anti-loosening nut is provided with a limiting groove, so that the fixing rubber can be snapped and fixed in the limiting groove.

[0013] In some embodiments, the rotating assembly includes a connecting plate and a rotating shaft. The first hoop and the second hoop are respectively provided with corresponding connecting plates, and a pair of rotating shafts that can rotate relative to each other are embedded between a set of connecting plates. The first hoop and the second hoop achieve relative rotation via the rotating shafts.

[0014] In some embodiments, the hollow cavity of the rotating shaft is provided with the steel cable, one end of which is connected to the outer wall of the first hoop, and the other end of which is connected to the outer wall of the second hoop.

[0015] In some embodiments, a collection assembly is provided between the native trees and located below the retaining posts. The collection assembly is used to collect gravel that can pass through the gaps between the retaining posts. The collection assembly includes a collection box and a wire mesh. The collection box is anchored to the slope below the retaining posts, and the opening of the collection box faces the retaining posts. The collection box contains a wire mesh that can buffer falling gravel.

[0016] In some embodiments, the retaining wall is further provided with an early warning component, which includes a steel wire rope, a fixing member, a tension sensor, an alarm, and a controller. The steel wire rope runs along the retaining wall through the entire slope riprap protection structure. The end of the steel wire rope is fixed to the native tree via the fixing member. The tension sensor is provided at the end of the steel wire rope. The tension sensor and the alarm are both communicatively connected to the controller. The tension sensor can detect changes in tension on the steel wire rope. If the controller receives tension information from the tension sensor that does not meet an internal preset threshold, the controller controls the alarm to sound an alarm.

[0017] In some embodiments, the fence posts are made of round logs, which are made from trees that have been felled within the land acquisition area after the crowns and roots have been removed, and the length of the round logs is the spacing between the original trees.

[0018] The beneficial effects of this utility model are:

[0019] 1. The first hoop secures the native trees on the slope, while the second hoop fixes multiple retaining posts accordingly. This creates a protective structure between the native trees to prevent rockfalls from the slope, without affecting the growth of the native trees. Using native trees as anchor piles and the retaining posts made from felled timber within the acquired land area, the main body of the protective structure is formed by combining native and felled timber. This method utilizes locally sourced materials, resulting in lower costs and higher environmental value. Furthermore, compared to other protective structures that require transporting building materials to the site, this structure significantly reduces transportation costs.

[0020] 2. The hoop assembly adopts a detachable connection, which is convenient for disassembly and assembly, reusable, and has a short turnover cycle. The hoop assembly can also be spliced ​​during the logging season without occupying construction time. In this protective structure, the first and second hoops are locked using a locking device formed by rotating bolts and anti-loosening nuts. The bolt connection is convenient and quick, effectively improving construction efficiency. The anti-torsion pin and fixing rubber are used to further secure the anti-loosening nuts while facilitating operation, preventing the connection structure from loosening significantly under the impact of rolling stones, thus improving the stability of the opening and closing ports of the first and second hoops.

[0021] 3. This protective structure, by adding a collection component, uses the protective structure to block and protect large falling rocks from the slope, and uses the collection component to block and collect some small gravel that has broken out and can pass through the gaps in the retaining bars, so as to reduce the risk of small gravel falling further to the bottom of the slope for construction, and ensure the safety of the bottom of the slope.

[0022] 4. This protective structure incorporates early warning components on the retaining walls. After repeated impacts from rolling stones, localized damage may occur, significantly reducing the structure's safety. Failure to repair in time would pose a substantial safety hazard. The early warning components provide timely alerts when the impact reaches a certain threshold, notifying construction personnel to promptly repair the structure and ensuring its effectiveness as well as the safety of construction at the bottom of the slope.

Specific features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure.

[0032] The term "comprising" is open-ended. As used in the appended claims, it does not exclude additional structures or steps.

[0033] "First," "second," etc. As used in this article, these terms serve as labels for the nouns preceding them and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). Detailed Implementation

[0034] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0035] Combination Figures 1 to 6 As shown, this embodiment is a slope riprap protection structure, including multiple retaining bars 9 and hoop assembly 7. The hoop assembly 7 includes a first hoop 3 and a second hoop 6. Multiple retaining bars 9 are arranged between native trees 8 on the slope, and the multiple retaining bars 9 are arranged in a vertical array. The ends of the retaining bars 9 are connected to the native trees 8 via the hoop assembly 7. Specifically, the first hoop 3 and the second hoop 6 are rotatably connected via a rotating assembly. The first hoop 3 is used to wrap around and fix the native trees 8, and the second hoop 6 is used to connect and fix the ends of the retaining bars 9. With the native trees 8 as fixing piles, the multiple retaining bars 9 between the native trees 8 form a protective structure.

[0036] Furthermore, the fence poles 9 are made of round logs, which are made from trees that have been felled within the land acquisition area after the crowns and roots have been removed. The length of the logs is the same as the spacing between the original trees 8.

[0037] In some embodiments, the rotating assembly includes a connecting plate 13 and a rotating shaft 5. The first hoop 3 and the second hoop 6 are respectively provided with corresponding connecting plates 13. A pair of rotating shafts 5 that can rotate relative to each other are embedded between a set of connecting plates 13. The first hoop 3 and the second hoop 6 achieve relative rotation via the rotating shafts 5.

[0038] Furthermore, a steel cable is provided in the hollow cavity of the rotating shaft 5, with one end of the steel cable connected to the outer wall of the first hoop 3 and the other end of the steel cable connected to the outer wall of the second hoop 6.

[0039] A pair of rotating shafts 5 between the first hoop 3 and the second hoop 6 allow the first hoop 3 and the second hoop 6 to flexibly adjust their rotation angle according to the angle between the retaining pole 9 and the native tree 8. At the same time, steel cables are installed inside the rotating shafts 5, with the first hoop 3 and the second hoop 6 connected at both ends. This ensures that even if the first hoop 3 and the second hoop 6 break due to the impact of a large rolling stone, they can still be connected by the steel cables, preventing the sudden breakage of the first hoop 3 and the second hoop 6 from causing the falling stones to continue impacting the bottom of the slope, thus ensuring the stability of the connection structure between the retaining pole 9 and the native tree 8.

[0040] In some implementation schemes, such as Figure 2 and Figure 3As shown, both the first hoop 3 and the second hoop 6 are detachable and assembleable. Each hoop 3 and the second hoop 6 includes a thin plate 1, a pin 2, and a locking element. Multiple arc-shaped thin plates 1 are connected by the pin 2, and the opening / closing port formed by the connection of the multiple thin plates 1 is closed and fixed by the locking element. Specifically, in this embodiment, the locking element uses a rotating bolt 4 and a lock nut 10. One end of both the first hoop 3 and the second hoop 6 is provided with a guide groove that can be adapted to the lock nut 10. The other end of the first hoop 3 and the second hoop 6 is rotatably connected to the rotating bolt 4 via a rotating shaft. The rod end of the rotating bolt 4 is fixed by rotating the lock nut 10 into the guide groove.

[0041] Furthermore, the number of thin plates 1 and pins 2 is determined based on the diameter of the native tree 8 and the diameter of the fence post 9. The circumference of the first hoop 3 and the second hoop 6 is adjusted by increasing or decreasing the number of thin plates 1 and pins 2, so that the diameter of the first hoop 3 is adapted to the diameter of the native tree 8 and the diameter of the second hoop 6 is adapted to the diameter of the fence post 9.

[0042] Furthermore, such as Figure 4 and Figure 5 As shown, the locking component also includes an anti-twist pin 11 and a fixing rubber 12. The anti-loosening nut 10 has a pair of insertion holes, and the opening and closing ports of the first hoop 3 and the second hoop 6 have through holes corresponding to the insertion holes, so that the anti-twist pin 11 can pass through the insertion holes and through holes to restrict the rotation of the anti-loosening nut 10. The end of the anti-twist pin 11 away from the anti-loosening nut 10 has a limiting groove, so that the fixing rubber 12 can be snapped and fixed in the limiting groove. Specifically, in this embodiment, the anti-twist pin 11 is U-shaped, and the opening and closing ports of the hoop assembly 7 can also be provided with multiple pairs of through holes according to the actual situation, so that the anti-loosening nut 10 can be adjusted to various tightnesses of the hoop assembly 7, and the insertion holes on the anti-loosening nut 10 can correspond to the through holes on the hoop assembly 7, so that the anti-twist pin 11 can pass through the insertion holes and through holes.

[0043] The first hoop 3 and the second hoop 6 are composed of a thin sheet 1, a pin 2, and a locking component. Since the diameters of the native trees 8 vary on-site, the number of thin sheets 1 and pins 2 can be flexibly adjusted using a detachable design, ensuring that the first hoop 3 matches the diameter of the native tree 8 and the second hoop 6 matches the diameter of the retaining wall 9. When it is necessary to close the opening / closing port on the first hoop 3 or the second hoop 6, the rotating bolt 4 is rotated so that its end is engaged in the guide groove. Then, the anti-loosening nut 10 is threadedly connected to the rotating bolt 4, and rotated into the guide groove to fix the rotating bolt 4, thus locking the opening / closing port of the first hoop 3 or the second hoop 6. When the anti-loosening nut 10 is rotated to the bottom of the guide groove, the insertion hole on the anti-loosening nut 10 is adjusted so that it corresponds to the through hole on the hoop. The anti-torsion pin 11 is passed through the insertion hole and the through hole, and then secured in the limiting groove at the end of the anti-torsion pin 11 using a fixing rubber 12 to prevent the anti-torsion pin 11 from dislodging from the rotating bolt 4. Meanwhile, all parts of the locking components can be quickly installed and disassembled, improving assembly efficiency. After the construction work at the bottom of the slope is completed, the relevant rolling stone protection structure on the slope can also be removed in a short period of time.

[0044] In some implementation schemes, such as Figure 6 As shown, a collection assembly is provided between the native trees 8, located below the retaining pole 9. The collection assembly is used to collect gravel that can pass through the gaps between the retaining poles 9. The collection assembly includes a collection box 14 and a wire mesh 15. The collection box 14 is anchored to the slope below the retaining pole 9, and the opening of the collection box 14 faces the retaining pole 9. The collection box 14 is provided with a wire mesh 15 that can buffer the falling gravel.

[0045] The retaining bars 9 can block some large falling rocks, but as these rocks fall down the slope, they may break off or drag existing loose rocks along with them. These loose rocks may pass through the gaps between the retaining bars 9. The collection box 14 can collect this loose rock. The wire mesh 15 inside the collection box 14 cushions the falling rocks, reducing their direct impact. This also facilitates the removal and cleanup of the loose rocks from the collection box 14 by construction workers.

[0046] In some implementation schemes, the retaining wall 9 is also equipped with an early warning component, which includes a steel wire rope, a fixing device, a tension sensor, an alarm, and a controller. The steel wire rope runs along the retaining wall 9 through the entire slope riprap protection structure, and the end of the steel wire rope is fixed to the native tree 8 by the fixing device. A tension sensor is installed at the end of the steel wire rope. Both the tension sensor and the alarm are communicatively connected to the controller. The tension sensor can detect changes in tension on the steel wire rope. If the controller receives tension information from the tension sensor that does not meet an internal preset threshold, the controller will activate the alarm. Specifically, in this embodiment, the alarm can be an audible and visual alarm to promptly alert construction personnel.

[0047] When the protective structure is subjected to repeated impacts from the rolling rocks on the slope, local structural breaks may occur. A steel wire rope is run through the entire protective structure along the circumferential direction of the retaining rod 9. The steel wire rope serves as the tension transmission medium for the entire protective structure, transmitting the impact force of the rolling rocks to the tension sensor. The tension sensor can continuously monitor the tension changes on the steel wire rope. If the tension information detected by the tension sensor exceeds the preset range inside the controller, the controller will activate the alarm, thereby facilitating construction personnel to promptly inspect the rolling rock protection structure, repair any breaks, reduce the risk of accidents, and improve the construction safety of the slope bottom project.

[0048] The implementation principle of a slope riprap protection structure is as follows:

[0049] By adjusting the number of thin plates 1 and pins 2, the diameter of the first hoop 3 is made consistent with that of the native tree 8, and the diameter of the second hoop 6 is made consistent with that of the log, ensuring a tight connection between the two. Loosen the locking nut 10, rotate the rotating bolt 4 to open the first hoop 3, wrap the first hoop 3 around the native tree 8, then rotate the rotating bolt 4 in the opposite direction and tighten the locking nut 10 to fix the first hoop 3 to the native tree 8. Place the log horizontally and arrange it neatly along the growth direction of the native tree 8. Rotate the rotating bolt placed on the second hoop 6 and tighten the locking nut 10 to fix the log to the native tree 8 via the hoop assembly 7. The log load is transferred to the native tree 8 through the hoop assembly 7. The arranged logs form a dense protective structure to block large boulders from falling from the slope.

[0050] The protective structure is constructed using native trees 8 and felled timber within the acquired land area, making full use of available materials, resulting in lower costs and higher environmental value. The native trees 8 are connected to the logs via hoop components 7, without affecting the growth of the native trees 8. Furthermore, the hoop components 7 are easy to assemble and disassemble, reusable, and can be used during the logging period without taking up time during construction.

[0051] Multiple collection boxes 14 are then anchored to the slope below the retaining pole 9. The wire mesh 15 inside the collection boxes 14 is used to mitigate the impact of falling rocks, and the collection boxes 14 collect the rocks. A portion of the wire rope is wound around the retaining pole 9, with the entire wire rope arranged laterally along the retaining pole 9. The ends of the wire rope are fixed to native trees 8 using fasteners. When the wire rope is fixed using fasteners, it is kept under a certain tension. Tension sensors installed at one or both ends of the wire rope detect the tension information, allowing the controller to issue timely warnings based on the tension information transmitted by the wire rope. This facilitates timely maintenance of the protective structure by construction personnel, thereby reducing the risks associated with construction at the bottom of the slope and improving the safety of rockfall protection.

[0052] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
