Description

Technical Field

[0001] This invention relates to the field of mortar anchor technology, and in particular to a mortar anchor for environmental engineering support and its construction method. Background Technology

[0002] In the support construction of environmental protection projects such as slope ecological restoration and abandoned mine management, it is often necessary to use mortar anchors for environmental engineering support to control the anchoring strength, environmental compatibility and durability, so as to avoid slope instability due to insufficient anchoring force, ecological pollution caused by improper selection of environmental protection materials, or support failure caused by corrosion and aging after long-term use, which will affect the safety of engineering construction, the effect of ecological restoration and the service life of support structure.

[0003] Existing mortar anchors used in environmental engineering support have significant deficiencies in support strength, ease of construction, and corrosion resistance. Their insertion process is typically a single insertion method, lacking multi-directional anchoring or segmented interlocking structures. This results in insufficient bonding strength between the anchor and the mortar and surrounding rock, leading to poor overall support stability and difficulty in effectively resisting lateral pressure from the soil and rock. Furthermore, the exposed portions of the anchors must be mechanically cut off, increasing construction steps and equipment investment. The cutting process also easily disturbs the already anchored mortar, affecting the integrity of the support structure. In addition, the outer ends of the anchors lack effective anti-corrosion protection, making them prone to corrosion when exposed to high humidity, leading to reduced cross-sectional strength, shortened anchor lifespan, and even the risk of support failure. This design not only reduces support reliability and increases construction costs but also threatens the safety of environmental engineering projects due to corrosion risks. The lack of functionality in anchor structure optimization, ease of construction, and corrosion protection limits the application effectiveness and durability of mortar anchors in environmental engineering support.

[0013] As a preferred embodiment of the mortar anchor rod for environmental engineering support described in this invention, wherein: the first drive rod is movably connected to the inner wall of the fixed plate via a rotating shaft; a sliding bearing is sleeved on the surface of the first drive rod; a guide block is fixed to the inner wall of the sliding bearing; a sliding groove that mates with the guide block is opened on the surface of the first drive rod; a guide rod is fixed to the inner wall of the sliding groove; the surface of the first drive rod is slidably connected to the inner wall of the guide block; a second spring is sleeved on the surface of the guide rod; a connecting buckle plate is fixed to the surface of the sliding bearing; a fixing socket that mates with the connecting buckle plate is fixed to the top of the outer shell; and a fixing socket that mates with the connecting buckle plate is fixed to the top of the first drive rod.

It enhances the overall support stability to resist the lateral pressure of the soil and rock mass. At the same time, it eliminates the mechanical cutting process and uses a one-button press to easily remove the extended section, avoiding disturbance to the anchored mortar during the cutting process, ensuring the integrity of the support structure, isolating it from high humidity air erosion to prevent corrosion, and avoiding a decrease in cross-sectional strength and a shortened service life.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1, referring to Figure 1 and Figure 2This is the first embodiment of the present invention, which provides a mortar anchor for environmental protection engineering support, the mortar anchor for environmental protection engineering support includes an anchor assembly 1 and a drive assembly 2.

[0039] Through the synergistic optimization of anchor bolt assembly 1 and drive assembly 2, significant defects such as insufficient anchoring strength of single insertion, cumbersome cutting of the extended section causing structural disturbance, and easy corrosion of the outer end are effectively solved. This enhances the overall support stability to resist the lateral pressure of the soil and rock mass. At the same time, it eliminates the mechanical cutting process and adopts a one-button press-type method to easily remove the extended section, avoiding disturbance to the anchored mortar during the cutting process, ensuring the integrity of the support structure, isolating it from high humidity air erosion to prevent corrosion, and avoiding reduction in cross-sectional strength and shortened service life.

[0040] Specifically, the anchor bolt assembly 1 includes a support anchor bolt 11, the inner wall of the support anchor bolt 11 is provided with a contact transmission component 14, the surface of the support anchor bolt 11 is provided with a through hole 13, and the inner wall of the through hole 13 is provided with a barbed reinforcement component 12.

[0041] Specifically, the drive assembly 2 is located on the top of the anchor bolt assembly 1, including a drive component 22 fixed to the top of the contact transmission component 14, a fixing component 21 is provided on the top of the anchor bolt 11, and an anti-corrosion component 23 is fixed on the top of the fixing component 21.

[0042] A connecting bearing is fitted onto the surface of the driving component 22, and a sliding block is fixed onto the surface of the connecting bearing. A groove that mates with the sliding block is provided on the inner wall of the fixing component 21. The two work together to ensure that the direction of movement remains stable during relative movement and that deviation is not likely to occur.

[0043] Specifically, the anti-corrosion component 23 includes an outer protective shell 231 fixed to the top of the fixed plate 211, a moisture-absorbing and pressurizing ring 233 is provided on the top of the outer protective shell 231, and a transmission rod 234 is fixed to the bottom of the moisture-absorbing and pressurizing ring 233.

[0044] The fastener 21 includes a fixing plate 211 set on the top of the supporting anchor rod 11. The outer shell 231 covers the core component on the top of the fixing plate 211 to isolate rainwater and dust and prevent corrosion. The moisture-absorbing and pressurizing ring 233 is made of moisture-absorbing material to absorb moisture from the outside air. After absorbing moisture and expanding, it transmits pressure downward through the transmission rod 234 to trigger subsequent anti-corrosion actions, and slowly releases internal moisture in sunny weather to complete its own drying.

[0045] Specifically, a pressing plate 237 is fixed to the bottom of the transmission rod 234, and a third spring 235 is sleeved on the surface of the transmission rod 234. The third spring 235 is fixed to the inner wall of the outer shell 231 and the top of the pressing plate 237 respectively. An elastic liquid bladder 236 is provided at the bottom of the pressing plate 237. The elastic liquid bladder 236 is fixed to the top of the fixing plate 211, and a feeding tube 232 is fixed to one side of the elastic liquid bladder 236.

[0046] The transmission rod 234 drives the pressing plate 237 to squeeze the elastic liquid bladder 236, and the third spring 235 buffers the pressure to prevent damage to the liquid bladder; the inner wall of the elastic liquid bladder 236 is provided with several one-way valve holes, and the anti-corrosion liquid inside is evenly coated on the surface of the fixed plate 211 and the inner wall of the outer shell 231 after being pressurized to form an anti-corrosion coating; the replenishment pipe 232 can replenish the anti-corrosion liquid regularly to ensure the continuous anti-corrosion effect.

[0047] Example 2, refer to Figures 2 to 12 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0048] Specifically, the barbed reinforcement 12 includes a movable shaft 122 fixed to the inner wall of the through hole 13, with irregular barbs 121 sleeved on the surface of the movable shaft 122, and a reset torsion spring 123 sleeved on the movable shaft 122.

[0049] The through hole 13 provides installation space for the barbed reinforcement 12, and the movable shaft 122 supports the irregular barb 121 to rotate around the shaft; the reset torsion spring 123 initially retracts the irregular barb 121 into the through hole 13 to avoid obstruction when the support anchor 11 is inserted into the soil; when the anchor is inserted into the soil, the soil pressure pushes the irregular barb 121 to unfold and penetrate the soil, which greatly improves the pull-out resistance and anchoring stability of the support anchor 11 and prevents loosening.

[0050] Specifically, the contact transmission component 14 includes a contact pressing seat 141 that is slidably connected to the inner wall of the support anchor rod 11. A fixing plug buckle 143 is fixed on the top of the contact pressing seat 141, and a fixing plug block 142 that cooperates with the fixing plug buckle 143 is fixed on the inner wall of the support anchor rod 11.

[0051] After the fixed plug-in buckle 143 rotates, it engages with the fixed plug-in block 142 to position the contact pressing seat 141, while providing stable power transmission support for the driving component 22 and preventing component displacement during the driving process.

[0052] Specifically, a positioning threaded cylinder 212 is embedded in the top of the fixing plate 211, a support rod 215 is fixed in the bottom of the fixing plate 211, a sliding sleeve 217 is fixed in the bottom of the support rod 215, a fixing post 219 is slidably connected to the inner wall of the sliding sleeve 217, a first spring 218 is sleeved on the surface of the fixing post 219, the fixing post 219 is fixed to the top of the support anchor rod 11, and a limit block 216 is fixed in the top of the fixing post 219.

[0053] The fixing plate 211 is the core load-bearing component at the top of the anchor rod. The positioning threaded cylinder 212 is connected to the external structure by bolts to achieve overall fixation of the anchor rod. The limiting block 216 restricts the stroke of the sliding sleeve 217 to prevent it from falling off.

[0054] Specifically, the fixing component 21 also includes a fixed pulley 214 fixed to the top of the supporting anchor rod 11. A transmission steel cable 213 is sleeved on the surface of the fixed pulley 214. The transmission steel cable 213 is fixed to the surface of the fixing plate 211 and the driving component 22 respectively.

[0055] In the initial state, the positioning threaded cylinder 212 does not contact the threaded hole, and there is a certain gap between them. It is impossible to directly feed the threaded cylinder 212 into the inner wall of the threaded hole by rotating it. Therefore, the fixed pulley 214 and the transmission cable 213 are used. Under the upward pulling action of the support anchor 11, the fixed plate 211 is quickly driven to move downward, so that the positioning threaded cylinder 212 fits into the corresponding threaded hole. This ensures the ease of use of the main body and the continuity of user experience, and avoids the need for workers to press the fixed plate 211 separately to adjust the position of the main body. The fixed pulley 214 changes the force direction of the transmission cable 213, so that the power of the driving component 22 can be transmitted to the fixed plate 211. When the driving component 22 moves, it pulls the transmission cable 213, which drives the fixed plate 211 to make fine adjustments to its position, so as to quickly position it.

[0056] Specifically, the driving component 22 includes a first driving rod 221 movably connected to the inner wall of the supporting anchor rod 11, a second driving rod 223 at the bottom of the first driving rod 221, the second driving rod 223 fixed to the top of the contact pressing seat 141, a plug-in spline 225 fixed at the bottom of the first driving rod 221, a rotary spline groove 224 that mates with the plug-in spline 225 opened at the top of the second driving rod 223, a positioning pin 2212 fixed at the bottom of the first driving rod 221, and a transmission steel cable 213 sleeved on the surface of the positioning pin 2212.

[0057] The first drive rod 221 is a power input component, and the second drive rod 223 is connected to the transmission component 14. The insert spline 225 cooperates with the rotary spline groove 224, which can ensure the connection between the first drive rod 221 and the second drive rod 223 by rotational limiting. This ensures that the rotational power of the first drive rod 221 is synchronously transmitted to the second drive rod 223, while allowing slight axial movement of both to accommodate installation errors or soil deformation and prevent transmission jamming. The transmission cable 213 is sleeved on the surface of the positioning pin 2212. When it is necessary to disassemble the drive component 22, the two transmission cables 213 can be moved in opposite directions to separate them from the positioning pin 2212.

[0058] Specifically, the first drive rod 221 is movably connected to the inner wall of the fixed plate 211 via a rotating shaft. A sliding bearing 226 is sleeved on the surface of the first drive rod 221. A guide block 2211 is fixed on the inner wall of the sliding bearing 226. A sliding groove 222 that cooperates with the guide block 2211 is opened on the surface of the first drive rod 221. A guide rod 227 is fixed on the inner wall of the sliding groove 222. The surface of the first drive rod 221 is slidably connected to the inner wall of the guide block 2211. A second spring 228 is sleeved on the surface of the guide rod 227. A connecting buckle plate 2210 is fixed on the surface of the sliding bearing 226. A fixed socket 229 that cooperates with the connecting buckle plate 2210 is fixed on the top of the outer shell 231.

[0059] Example 3, referring to Figures 2 to 12 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0060] Specifically, the following construction method is also included: When using it, the user first drills a hole at the location where the anchor rod needs to be installed through the drilling mechanism, then inserts the support anchor rod 11 of the anchor rod assembly 1 into the drilled hole, and then pulls the first drive rod 221 of the drive member 22 upward. The first drive rod 221 cooperates with the rotary spline groove 224 of the second drive rod 223 through the bottom insertion spline 225, driving the second drive rod 223 and the contact pressing seat 141 of the contact transmission member 14 to move upward. The contact pressing seat 141 presses the irregular barb 121 of the barb reinforcement member 12, so that the irregular barb 121 rotates around the movable shaft 122 and fully extends. The overall stability of the support anchor rod 11 is improved by multi-directional insertion.

[0061] The user then rotates the first drive rod 221 clockwise, which in turn drives the contact pressing seat 141 to rotate synchronously via the second drive rod 223. This causes the fixed insertion buckle 143 on the top of the contact pressing seat 141 to engage with the fixed insertion block 142 on the inner wall of the support anchor rod 11, thus fixing the position of the contact pressing seat 141 and preventing it from moving downwards.

[0062] During the upward pulling of the first drive rod 221, the first drive rod 221 drives the fixing plate 211 of the fixing member 21 to fit against the contact surface via the transmission steel cable 213 and the fixed pulley 214. The support rod 215 at the bottom of the fixing plate 211 drives the sliding sleeve 217 to slide along the fixing column 219. The first spring 218 assists in buffering. At the same time, the positioning threaded cylinder 212 at the top of the fixing plate 211 is inserted into the preset threaded hole to achieve quick positioning. Then, the bolt is screwed into the positioning threaded cylinder 212 to complete the installation of the fixing member 21.

[0063] If disassembly is required, manually press down on the sliding bearing 226. The sliding bearing 226 moves down along the sliding groove 222 of the first drive rod 221. The guide block 2211 slides along the guide rod 227 and compresses the second spring 228. At the same time, the connecting buckle 2210 on the surface of the sliding bearing 226 disengages from the fixed socket 229 at the top of the first drive rod 221. After releasing the buckle, continue to rotate the first drive rod 221 clockwise so that the insert spline 225 and the rotary spline groove 224 no longer rotate and lock. Then, gently pull the first drive rod 221 upward to complete the disassembly. Afterward, attach the sealing cover to the top of the second drive rod 223 to achieve a sealed seal.

[0064] When rainy weather arrives and air humidity increases, the moisture-absorbing and pressure-increasing ring 233 of the anti-corrosion component 23 absorbs moisture and quickly increases in weight, pressing down on the transmission rod 234. The transmission rod 234 drives the pressing plate 237 to squeeze the elastic liquid bladder 236. The anti-rust and anti-corrosion protective liquid inside the elastic liquid bladder 236 is squeezed out and seals and protects each connection point by slowly seeping out. If the protective liquid is insufficient, it can be replenished through the replenishment pipe 232.

[0065] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
