DETAILED DESCRIPTION

[0024] Anchor rods, as a tensile member that penetrates deep into the stratum, are connected to engineering structures at one end and penetrate deep into the stratum at the other end. It is mainly composed of a rod body, an anchor head, an anchoring agent (used by some anchor rods), etc., and is a rod system structure for rock and soil reinforcement. Through the longitudinal tension of the rod body, the anchor rod overcomes the disadvantage that the tensile capacity of the rock and soil is far lower than the compressive capacity. From a macroscopic point of view, it increases the cohesion of the rock and soil. From a mechanical point of view, it increases the cohesion C and internal friction angle φ of the surrounding rock mass. After the anchor rod is combined with the rock and soil, a new composite is formed. The anchor rod in this composite is the key to solving the low tensile capacity of the surrounding rock mass, thereby significantly enhancing the bearing capacity of the rock and soil itself. There are various types of anchor rods, including but not limited to full-length bonded anchor rods, prestressed anchor rods, friction anchor rods, self-drilling anchor rods, seam pipe anchor rods, flower tube grouting anchor rods, and water expansion anchor rods. These different types of anchor rods have their own unique characteristics and application scenarios according to different engineering requirements and geological conditions.

[0025] In underground mines such as coal mines, anchor rods are the most basic component of tunnel support. It reinforces the surrounding rock of the tunnel so that the surrounding rock supports itself, thereby improving the stability and safety of the tunnel. In mine tunnels, the application of anchor rods not only reduces the consumption of support materials, but also reduces support costs and improves mining efficiency. In engineering construction in mountainous or hilly areas, the stability of the slope is a key issue. By penetrating into the stratum and applying prestress, the anchor rod can effectively reinforce the slope to prevent it from landslide or collapse. Especially in some projects with complex geological conditions and high slope heights, the application of anchor rods is particularly important. In tunnel engineering, anchor rods also play an important role. It can be used not only for the initial support of the tunnel, but also for the permanent support of the tunnel. Through the reinforcement of the anchor rod, the stability and bearing capacity of the tunnel can be improved, and the tunnel can be prevented from deformation or damage during construction or operation. In water conservancy projects, the stability of the dam body is directly related to the safety of the project. Anchor rods can effectively reinforce the dam body and improve its anti-sliding stability and bearing capacity by penetrating deep into the dam body and applying prestress. The application of anchor rods is especially indispensable in some high dams, large dams or dams with complex geological conditions. Anchor rods also play an important role in geotechnical engineering. It can not only be used for the reinforcement and stabilization of rock and soil, but also for the development and utilization of underground space. Through the reinforcement of anchor rods, the bearing capacity and stability of rock and soil can be improved, providing a strong guarantee for the development and utilization of underground space.

[0026] The characteristic of full-length bonded anchor is that the entire length of the anchor hole is filled with bonding materials, such as cement mortar, resin, etc. This type of anchor is suitable for various geological conditions, especially when the deformation of the surrounding rock is not large. Through the action of the bonding material, the full-length bonded anchor can tightly combine the anchor with the surrounding rock to form an integral structure, thereby improving the bearing capacity and stability of the surrounding rock. Prestressed anchors apply prestress before the anchor is installed to improve the support effect. This type of anchor is suitable for the system support of large-span high-side wall tunnels and the local support of large unstable blocks. By applying prestress, the prestressed anchor can actively resist the deformation and destruction of the surrounding rock, thereby improving the stability and safety of the tunnel. The friction type anchor relies on the friction between the anchor body and the hole wall to anchor. This type of anchor is suitable for weak and broken, plastic rheological surrounding rocks and mine tunnel projects that are subjected to blasting vibration. By increasing the friction between the anchor body and the hole wall, the friction type anchor can effectively prevent the loosening and falling of the surrounding rock and improve the stability and safety of the tunnel. The self-drilling anchor rod itself has the function of drilling a hole, combining drilling, grouting and anchoring into one. This type of anchor rod is suitable for occasions that require rapid support, such as tunnel projects such as highways and subways. Through the application of self-drilling anchor rods, the drilling, grouting and anchoring of anchor rods can be completed quickly, thereby improving the support efficiency and quality. The seam-tube anchor rod is a thin-walled steel pipe with a longitudinal seam that is forcibly pushed into a borehole smaller than its outer diameter, and the radial pressure of the steel pipe on the hole wall is used to generate resistance to play an anchoring role. This type of anchor rod is suitable for supporting soft and broken surrounding rocks. Through the application of the seam-tube anchor rod, the soft and broken surrounding rocks can be effectively reinforced to improve their bearing capacity and stability.

[0027] Anchor rod recycling has significant significance in geotechnical engineering and underground space development, mainly reflected in resource conservation, environmental protection, economic benefits and engineering safety. Resource conservation: Anchor rods are usually made of metal materials such as steel and are recyclable resources. By recycling anchor rods, the demand for raw materials can be reduced, thereby reducing the pressure on the exploitation of natural resources. With the increasing shortage of global resources, recycling and reusing waste materials has become an important way to alleviate the problem of resource shortage. Anchor rod recycling is in line with this trend and helps to achieve sustainable utilization of resources. Environmental protection: Anchor rods are widely used in underground projects. If they are not recycled in time, they will remain underground for a long time, which may cause pollution to the soil and groundwater. Recycling anchor rods can reduce this potential environmental risk. In the process of anchor rod recycling, through reasonable treatment processes, waste emissions can also be reduced and negative impacts on the environment can be reduced. Economic benefits: Anchor rod recycling can reduce engineering costs. After testing and processing, the recycled anchor rods can be reused in other projects, thus saving the cost of purchasing new anchor rods. In addition, anchor rod recycling can also promote the development of related industries, such as anchor rod recycling, processing and reuse, etc., bringing new growth points to the economy. Project safety: In some specific projects, such as foundation pit support and tunnel excavation, anchor rods play a key supporting role. However, as the project progresses, anchor rods may no longer be needed. At this time, timely recovery of anchor rods can prevent them from becoming a safety hazard. Recovering anchor rods can also reduce the occupation of underground space and facilitate the construction of other projects or facilities.

[0028] Mechanical extraction is one of the most common methods of anchor recovery. It uses mechanical devices such as jacks and clamps to pull the anchor out of the ground. This method is suitable for situations where the anchor is shallowly buried and the geological conditions are good. Before extraction, the anchor needs to be pre-tightened to ensure that it can be pulled out smoothly. The advantages of mechanical extraction are simple operation and low cost; the disadvantage is that it may cause certain damage to the underground structure.

[0029] The grouting dissolution method is suitable for anchors that use anchoring agents. By injecting a special dissolving agent into the anchor hole, the anchoring agent is dissolved, thereby releasing the anchor. This method causes less damage to underground structures, but it is necessary to ensure that the dissolving agent does not pollute the environment. The advantages of the grouting dissolution method are high recovery efficiency and little damage to underground structures; the disadvantages are high cost and complex operation.

[0030] The cutting recovery method is suitable for situations where the anchor is buried deep and the geological conditions are complex. The anchor is cut off at a certain depth below the surface by cutting equipment, and then the cut anchor part is pulled out by mechanical devices. This method can reduce the damage to the underground structure, but the safety and efficiency of the cutting process must be ensured. The advantages of the cutting recovery method are wide application range and little damage to the underground structure; the disadvantages are complex operation and high cost.

[0031] The comprehensive recovery method combines the advantages of mechanical extraction, grouting dissolution and cutting recovery methods. The most appropriate recovery method is selected according to the specific situation. Under some complex geological conditions, it may be necessary to use a combination of multiple recovery methods to recover anchor bolts. The advantages of the comprehensive recovery method are strong flexibility and high recovery efficiency; the disadvantages are complex operation and high cost.

[0032] Before recycling anchor rods, it is necessary to conduct a safety assessment of the underground structure to ensure that the recycling process will not cause damage to the underground structure or cause safety hazards. At the recycling site, operations should be carried out strictly in accordance with the recycling plan. Pay attention to safety issues during the operation, such as wearing protective equipment and avoiding misoperation. During the recycling process, close attention should be paid to the changes in the underground structure. If there is any abnormality, the recycling should be stopped immediately and measures should be taken to deal with it. The recycled anchor rods should be treated in an environmentally friendly manner, such as cleaning and rust removal. Ensure that the anchor rods meet relevant environmental protection standards before reuse. For the parts of the anchor rods that cannot be reused, they should be properly handled to avoid pollution to the environment. During the recycling process, data such as the recycling method, recycling quantity, and recycling cost should be recorded in detail. These data help evaluate the recycling effect and provide a reference for future recycling work. After the recycling is completed, the recycling process should be summarized and analyzed, and lessons learned should be summarized and improvement measures should be proposed.
