Description

Technical Field

[0001] This utility model belongs to the field of slope protection technology, specifically relating to a slope protection structure for fractured rock mass. Background Technology

[0002] Rough rock slopes are common in highway, railway, water conservancy, and mining projects. Because these slopes have a lot of loose rocks on their surface and usually lack a base layer for plant growth, the rock mass is directly exposed to the outside world. As a result, loose rocks are prone to falling off the slope under the influence of the external environment. Protective structures need to be set up to protect the slope in order to reduce or eliminate this safety hazard.

[0003] For slope structures with relatively flat rock surfaces and short slope lengths (often found on both sides of national highways or expressways), barriers and protective nets are usually used to shield and protect the slopes. However, the installation of barriers will cover the original topography, and the transportation and handling of barriers is cumbersome and labor-intensive. Therefore, protective nets, which are easier to transport and handle and do not completely cover the original topography, are usually used to protect and intercept rock slopes.

[0004] Existing protective netting requires anchoring bolts or driving rivets into the slope during installation to reinforce it. For slopes with short lengths, anchor bolts / rivets are generally only needed at the top and bottom ends. Because the protective netting is a flexible structure, a large number of anchor bolts / rivets need to be densely laid out laterally along the slope to effectively tension it. These anchor bolts / rivets must be driven in one by one using tools, resulting in low efficiency and making the installation time-consuming and unfavorable for the netting's laying and installation. Utility Model Content

[0005] The present invention aims to provide a slope protection structure for fractured rock masses that can reduce the amount of anchor bolts / rivets used and improve the efficiency of laying and installing protective netting.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fractured rock slope protection structure, installed on the main body of the slope, including... Protective netting is laid on the main body of the slope; The installation components include an installation plate, a connecting plate, an insert plate, and a limiting bolt. The installation plate is fixed to the upper and lower ends of the slope body, and the connecting plate is installed on the upper and lower sides of the protective net. The insert plate is detachably installed on the side wall of the connecting plate. The adjacent sides of the installation plate are respectively provided with slots and limiting grooves communicating with the slots. The insert plate can be inserted into the slots. The limiting bolt is slidably fitted in the limiting grooves, and the limiting bolt is threaded into the insert plate. The head of the limiting bolt abuts against the surface of the installation plate.

[0007] The principle and effects of this technical solution: 1. The mounting plate can be installed and fixed with a smaller number of anchor bolts / rivets, which reduces the number of anchor bolts / rivets used and saves the time required to drive in the anchor bolts / rivets, thus reducing the installation time of the protective net and improving the efficiency of the laying and installation of the protective net.

[0008] 2. The installation plate connects and limits the connecting plate, and also connects and limits the protective netting. This eliminates the need for anchoring anchors or riveting rivets on the slope during the installation of the protective netting. Only the stability between the connecting plate and the protective netting, the connecting plate and the installation plate, and the installation plate and the main slope structure need to be ensured. This provides a stable protective effect on the main slope structure through the protective netting. The installation plates are located on the upper and lower sides of the main slope structure, making it easier and more convenient for workers to anchor the installation plates to the slope structure without damaging the surface structure of the slope. This method is convenient and highly safe.

[0009] 3. By sliding the insert plate in the slot, cooperating with the limiting bolt and the limiting groove, and limiting the insert plate, the position of the connecting plate can be adjusted relative to the mounting plate, so that the installation position can be adjusted according to the actual situation. Moreover, the limitation of the insert plate by the limiting bolt enables the insert plate to drive the connecting plate to achieve a stable limiting effect on the protective net.

[0010] The present invention is further provided with: multiple connecting plates that are rotatably connected to each other on both sides of the protective net.

[0011] The principle and effect of this technical solution: By setting up multiple rotating and connected connecting plates, the angle between the connecting plates can be changed and adjusted, so that the angle between the connecting plates can be adapted to the actual setting of the protective net, so that the connecting plates will not interfere with the protective net's coverage of the slope.

[0012] The present invention is further configured such that: the mounting assembly also includes a rotating plate, and rotating grooves are respectively opened on the left and right sides of the connecting plate. A rotating plate is rotatably installed in the two rotating grooves on opposite sides of the two adjacent connecting plates, and the side walls of the two adjacent connecting plates rotate and abut against each other.

[0013] The principle and effect of this technical solution: By connecting two adjacent connecting plates with a rotating plate, the two connecting plates can be rotated to completely overlap, which facilitates folding and storage. The adjustable angle range is large, making it easier to adapt to slope structures with different flatness. The connecting plate will not interfere with the protective net's coverage effect on the slope during use.

[0014] The present invention is further configured such that: the end of the insert plate has an insert rod, the insert rod includes an anti-rotation end and a mating end, the anti-rotation end is connected to the insert plate, the mating end is located on the side of the anti-rotation end away from the insert plate, the side wall of the connecting plate is provided with an anti-rotation groove, the projection of the mating end on the insert plate is located inside the projection of the anti-rotation end on the insert plate, the anti-rotation end is adapted to the anti-rotation groove, and a limit nut is threaded on the mating end, the limit nut abuts against the side of the connecting plate away from the insert plate.

[0015] The principle and effect of this technical solution: By cooperating with the anti-rotation end and the anti-rotation groove, the positional relationship between the insert plate and the connecting plate can be limited. Furthermore, by locking the limit nut, the insert rod can be stably connected to the insert plate. Moreover, by rotating the limit nut, the restriction on the insert rod can be released. Thus, the number of insert plates can be increased or decreased according to the actual situation, making the use more flexible.

[0016] The present invention is further configured such that the length of the anti-rotation end is less than the length of the anti-rotation groove.

[0017] The principle and effect of this technical solution: By making the length of the anti-rotation end less than the length of the anti-rotation groove, a part of the mating end can be located in the anti-rotation groove, thereby allowing the limit nut to be tightly pressed against the surface of the connecting plate.

[0018] The present invention is further configured such that the protective net and the connecting plate are detachably connected.

[0019] The principle and effect of this technical solution: Through the detachable design, protective nets of different lengths can be used with the connecting plate, so that the device does not need to be completely replaced or customized when intercepting and protecting slopes of different lengths, making it more versatile.

[0020] The present invention is further configured such that the mounting plate is anchored to the main body of the slope.

[0021] The principle and effect of this technical solution: Since the mounting plate is located at the upper and lower ends of the main body of the slope, it is more convenient to anchor the mounting plate and easier to construct.

[0022] The present invention is further configured such that: a plurality of limiting holes are spaced apart on the side of the connecting plate away from the limiting groove, and the end of the limiting bolt can extend into the limiting hole.

[0023] The principle and effect of this technical solution: By limiting the end of the limiting bolt through the limiting hole, the position of the limiting bolt can be restricted, so that the position of the limiting bolt does not need to be restricted by the friction between the limiting bolt and the mounting plate alone. This results in greater stability and makes the protective net less likely to slide laterally. Attached Figure Description

Main body of the slope; 210. Protective netting; 310. Mounting plate; 311. Slot; 312. Limiting groove; 313. Limiting hole; 320. Connecting plate; 321. Rotation groove; 322. Anti-rotation groove; 330.

[0026] Example: As attached Figure 1-4 As shown, this utility model discloses a slope protection structure for fractured rock masses, installed on a slope body 110, including a protective net 210 and installation components. The protective net 210 is laid on the slope body 110, and installation components are respectively installed on the upper and lower sides of the protective net 210. The installation components include an installation plate 310, a connecting plate 320, an insert plate 330, a rotating plate 350, and limiting bolts 340. The installation plate 310 is fixed to the upper and lower ends of the slope body 110, respectively. The installation plate 310 is fixed to the upper and lower sides of the slope body 110 by anchoring with anchor bolts, which is safer and more convenient than anchoring on the slope surface of the slope body 110. The upper and lower sides of the protective net 210 are respectively... Multiple connecting plates 320 are arranged in sequence. Each connecting plate 320 has a rotating groove 321 on its left and right sides. A rotating plate 350 is rotatably installed in the two rotating grooves 321 on opposite sides of two adjacent connecting plates 320. The side walls of the two adjacent connecting plates 320 rotate and abut against each other. The two connecting plates 320 are rotatably connected by the rotating plate 350, so that the angle between the connecting plates 320 can be flexibly controlled, so that the flatness of the protective net 210 can be adjusted according to the slope conditions.

[0027] The end of the insert plate 330 has an insert rod, which includes an anti-rotation end 410 and a mating end 420. The anti-rotation end 410 is connected to the insert plate 330, and the mating end 420 is located on the side of the anti-rotation end 410 away from the insert plate 330. The side wall of the connecting plate 320 has an anti-rotation groove 322. The projection of the mating end 420 on the insert plate 330 is located inside the projection of the anti-rotation end 410 on the insert plate 330. The anti-rotation end 410 is adapted to the anti-rotation groove 322. A limit nut 430 is threaded onto the mating end 420, and the limit nut 430 abuts against the side of the connecting plate 320 away from the insert plate 330. The insertion plate 330 can be adjusted according to actual conditions without installing all the connecting plates 320. The detachable design facilitates separate folding and storage, allowing the connecting plates 320 to be folded and stored individually without interference from the insertion plates 330. The length of the anti-rotation end 410 is less than the length of the anti-rotation groove 322.

[0028] The mounting plate 310 has slots 311 and limiting grooves 312 connected to the slots 311 on its adjacent sides. The insert plate 330 can be inserted into the slot 311. The limiting bolt 340 is slidably fitted into the limiting groove 312 and threaded into the insert plate 330. The head of the limiting bolt 340 abuts against the surface of the mounting plate 310. The connecting plate 320 has multiple limiting holes 313 spaced apart on the side away from the limiting groove 312. The end of the limiting bolt 340 can extend into the limiting hole 313.

[0029] The protective net 210 is detachably connected to the connecting plate 320. A hook can be fixed on the connecting plate 320, and a hanging ring is provided on the protective net 210. The protective net 210 and the connecting plate 320 can be detachably connected by hanging the hanging ring on the hook, or the protective net 210 can be installed on the connecting plate 320 by bolts or other means. The rotation between the connecting plates 320 and the connecting plate 320 ensures that the connecting plate 320 will not affect the protective effect of the protective net 210.

[0030] In practical use, rivets can be riveted to the protective netting 210 located on the upper and lower sides. By riveting the rivets to the upper and lower sides of the slope body 110, the protective netting 210 is reinforced, making it more stable and allowing it to be more stably installed on the slope body 110 without relying solely on installation components. This results in more even and reliable stress distribution. Furthermore, the method of riveting on the upper and lower sides prevents workers from being completely on the slope surface, thus reducing safety and making the operation more convenient.

[0031] Because the anchoring force direction of the mounting plate 310 to the slope body 110 is not parallel to the direction of the tensile force exerted by the protective net 210 on the mounting plate 310, the anchoring stability and reliability are strong. Furthermore, the upper and lower sides of the slope body 110 are leveled (usually with a walkway or pressure beam on the upper side, and a smooth cement surface on the lower side to prevent large-scale collapse), allowing the mounting plate 310 to abut against both sides of the slope body 110. Multiple mounting plates 310 are arranged transversely along the slope body 110.

[0032] The parts of the device not covered herein are the same as or can be implemented using existing technologies.

[0033] Among them, insert and sliding insert are mating bodies with holes, the cross section of the shaft or rod matches the hole, and the shaft or rod can slide relative to the hole. Threaded insert is a hole with threads, the shaft or rod is threaded, and the shaft or rod is connected to the mating body by screwing. Detachable installation can be by bolt thread connection or bolt and nut connection, etc., depending on what can be actually achieved.
