Rope-Plug Linkage Landscape Anchors for Falling Dangerous Rock Prevention

Abstract

The invention discloses a net-rope-and-plug-linked-type landscape anchoring device used for preventing falling type dangerous rock. The net-rope-and-plug-linked-type landscape anchoring device is characterized by comprising a plurality of anchoring units distributed on the periphery of the dangerous rock, a protective net for covering the surface of the dangerous rock and landscape objects attached to the protective net; each anchoring unit comprises a plug and a reverse-pulling cylinder, wherein the plug is inserted and clamped into the reverse-pulling cylinder to achieve connection of the plug and the reverse-pulling cylinder; the reverse-pulling cylinders and a parent rock mass are connected in an anchored mode through mortar; each plug comprises a pencil-shaped body, and each body is provided with a plurality of barb grooves and a plurality of barbs at intervals; the barb grooves of the plugs are cuboid grooves, and the length of the barb grooves is coincident with the length of the barbs; the barbs are hinged to the sides of the barb grooves through studs and meanwhile elastically supported by stretchable devices; the reverse-pulling cylinders of the plugs are rectangular columns, a plurality of barb clamping grooves are evenly formed in each reverse-pulling cylinder, four penetrating reinforcing steel bar holes are preserved in each reversing-pulling cylinder, four penetrating reinforcing steel bars are arranged in each reversing-pulling cylinder, and the barb clamping grooves are wedge-shaped grooves. According to the net-rope-and-plug-linked-type landscape anchoring device, the rock mass of the dangerous rock is not damaged, and construction is rapid and convenient; the net-rope-and-plug-linked-type landscape anchoring device has the advantage of achieving landscape repairing.

Description

technical field [0001] The invention belongs to the technical field of dangerous rock protection. Background technique [0002] my country has a vast land area, among which mountains, plateaus and other areas account for 78% of the total area, and the rest are plain areas. In Tibet, Gansu, Xinjiang, Yunnan, Chongqing and other western regions of China, there are hundreds of millions of dangerous rock masses with serious safety hazards along highways, mines and urban areas. Dangerous rock mass has the characteristics of sudden instability and collapse, unpredictable fissure development, and poor connection stability with the parent rock mass, which is an important cause of major geological disasters and has a huge impact on society. For example, in October 2002, the Laogou River in Paomuyuan Village, Gaoleshan Township, Xianfeng County, Hubei Province was about 100m long, 120m high, and 25,000m in volume. 3 On June 5, 2009, a rock mass collapse occurred in Jiwei Mountain, W...

Problems solved by technology

These methods are permanent treatment techniques, which require prior survey, feasibility analysis, preliminary design, construction drawing design and other construction procedures. The treatment time takes more than 3 months, and the construction even takes more than 1 year, making the treatment project difficult and long. , cannot meet the needs of emergency relief

Moreover, the above control measures need to go through steps such as drilling the dangerous rock itself, and there is no treatment method for landscape restoration, so there are few rope-plug linkage landscape anchoring devices for dangerous rocks that prevent falling of dangerous rocks Methods

[0004] Chinese patent CN202577323U has a large-volume dangerous rock surface crack tie reinforcement structure, which adopts the first reinforcement column that penetrates into the parent rock body and the second reinforcement column that penetrates into the dangerous rock body, and the first reinforcement column and the second reinforcement column pass through the tie beam. The method of connecting together is used to reinforce the dangerous rock, but this method needs to be reinforced after drilling the dangerous rock during construction, which destroys the stability of the dangerous rock itself and has the risk of causing the collapse of the dangerous rock

[0005] Chinese patent CN101725143A dangerous rock emergency reinforcement bolts and its production and installation method, this method needs to perforate the dangerous rock, which destroys the stability of the dangerous rock, and is only applicable to the dangerous rock whose thickness is not more than 3m, and the scope of application is not Second, the bolts are susceptible to moisture and corrosion, and their service life is limited

[0006] Chinese patent CN1884718 dangerous rock support-anchor combined support treatment method requires steps such as determining the reinforcement position and finding the main control surface in operation. The design and survey process is cumbersome and requires a long preparation time.

At the same time, it is necessary to implement super-long drilling in dangerous rocks, which will cause artificial damage to dangerous rocks. Improper construction may lead to geological disasters.
