Abstract
Description
Technical Field
[0001] The present application relates to the fields of geological disaster control and slope control, and particularly relates to a two-way double energy-absorbing anchor rod. Background Technique
[0002] As a tensile member penetrating into the formation, one end of the anchor rod is connected to the engineering structure, and the other end penetrates into the formation. The whole anchor rod is divided into a free section and an anchorage section. The free section refers to the area that transmits the tension at the anchor rod head to the anchor body, and its function is to apply prestress to the anchor rod.
[0003] In the related art, the anchor rod expands and contracts under the influence of thermal expansion and contraction of the formation. During the expansion and contraction process of the anchor rod, it will squeeze the soil wrapped around its circumference. If the soil texture is hard, when the anchor rod squeezes the soil, it will be broken or cracked. Especially when the anchor rod is buried inside the cement, the cement texture is hard, and the anchor rod is easily broken during expansion and contraction, which seriously affects the anchoring effect of the anchor rod and is not conducive to the long-term use of the anchor rod. Utility Model Content
[0004] The present application provides a two-way double energy-absorbing anchor rod, aiming to effectively ensure its own structural strength when the anchor rod undergoes thermal expansion and contraction in the formation, effectively prevent the anchor rod from being squeezed and broken by the surrounding soil, and thus is conducive to ensuring its long-term anchoring effect.
[0005] The present application provides a two-way double energy-absorbing anchor rod, adopting the following technical solution:
[0006] A two-way double energy-absorbing anchor rod includes an anchor rod body and an expansion assembly. The expansion assembly includes an expansion member and an expansion sleeve. The expansion sleeve is sleeved on the periphery of the anchor rod body. The expansion member is sleeved between the anchor rod body and the expansion sleeve, and both the upper and lower ends of the expansion member are connected to the expansion sleeve. The expansion member and the expansion sleeve are used to strengthen the connection strength between the anchor rod body and the soil.
[0007] By adopting the above technical solution, when the anchor rod undergoes thermal expansion and contraction in the formation, the connection between the anchor rod body and the formation soil becomes closer through the expansion member and the expansion sleeve, and thus it can effectively prevent the anchor rod from being squeezed and broken by the surrounding soil, which is conducive to ensuring the long-term anchoring effect of the anchor rod body in the formation.
[0008] Preferably, both the left and right ends of the expansion member are sleeved on the anchor rod body, both the upper and lower ends of the expansion member are connected to the inner wall of the expansion sleeve, both the upper and lower ends of the expansion member are in a "V" shape structure, and both the end of the expansion member connected to the expansion sleeve and the end of the expansion member connected to the anchor rod body are inclined.
[0009] By adopting the above technical solution, in this design method, when the anchor rod body expands and contracts due to the influence of thermal expansion and contraction in the formation, the upper and lower ends of the expansion member can quickly and effectively push the inner walls on both sides of the expansion sleeve away from each other, thereby being able to adjust the diameter of the expansion sleeve, enabling the upper and lower sides of the expansion sleeve to quickly combine with the surrounding soil, and further effectively strengthening the connection strength between the anchor rod body and the soil through the expansion sleeve.
[0010] Compared with the traditional anchor rod anchoring method, in this anchoring method, the anchor rod is set to be in a tightly connected state with the soil in the formation during the expansion and contraction process through the expansion member and the expansion sleeve. By adding force points on the periphery of the anchor rod through the expansion member and the expansion sleeve, the anchor rod can be connected to the surrounding soil through these force points during the expansion and contraction process. At the same time, during the process of effectively strengthening the connection strength between the anchor rod body and the formation soil through the expansion member and the expansion sleeve, the anchor rod body is not directly connected to the soil in the formation, which can effectively avoid the problem that the anchor rod body is in long-term friction with the soil during the long-term burial in the formation, resulting in cracks on the anchor rod body, and further effectively ensure the structural strength of the anchor rod body itself, and further ensure the effect of the long-term anchoring of the anchor rod body in the formation.
[0011] Preferably, a plurality of groups of the expansion assemblies are evenly arranged at intervals along the length direction of the anchor rod body.
[0012] By adopting the above technical solution, using these expansion assemblies can enable the anchor rod body to be tightly connected to the soil in the formation at multiple different positions on the anchor rod body during the expansion and contraction process of the formation. Thus, when the anchor rod body expands and contracts, the connection between the anchor rod body and the soil can be more uniform, and there will be no problem that the connection effect between some positions of the anchor rod body and the soil is good while that of some positions is poor, and further the connection effect between the anchor rod body and the formation soil can be increased.
[0013] Preferably, a telescopic spring is sleeved on the periphery of the anchor rod body, and the telescopic spring is located between the expansion sleeve and the anchor rod body.
[0014] By adopting the above technical solution, when the anchor rod body expands and contracts in the formation due to the influence of thermal expansion and contraction, the telescopic spring can effectively buffer and reset the anchor rod body during the expansion and contraction process of the anchor rod body. Using the telescopic spring to buffer the expansion of the anchor rod body can effectively avoid damage to the structure of the anchor rod body caused by overheating and excessive expansion. At the same time, during the cold retraction process of the anchor rod body, it can drive the anchor rod body to retract, and further effectively accelerate the retraction efficiency of the anchoring body.
[0015] Preferably, a reinforcing member is integrally added to the outer periphery of the expansion sleeve.
[0016] By adopting the above technical solution, when the anchor rod body expands and contracts due to the influence of thermal expansion and contraction of the formation, the expansion sleeve is tightly connected to the soil of the formation through the driving of the expansion member. During the expansion process of the expansion sleeve, the reinforcing member is affected by the expansion of the expansion sleeve and generates extrusion with the soil of the formation. By utilizing the extrusion of the reinforcing member on the soil, the soil is broken open, so that the circumferential side of the expansion sleeve can smoothly enter the soil. Furthermore, by means of the reinforcing member, the connection between the expansion sleeve and the formation soil can be made more rapid and effective. Thus, when the anchor rod body expands and contracts, the reinforcing member can quickly and tightly connect the expansion sleeve and the soil, so that the anchor rod body can be quickly and tightly connected to the soil. Rapidly and effectively connecting the anchor rod body to the formation soil can reduce the damage to the structure of the anchor rod body itself during the expansion and contraction process, and further ensure the long-term anchoring effect of the anchor rod body.
[0017] Preferably, a plurality of the reinforcing members are provided, and the plurality of reinforcing members are evenly distributed at intervals along the length direction of the expansion sleeve.
[0018] By adopting the above technical solution, these reinforcing members can effectively ensure that different positions of the anchor rod body are quickly and effectively combined with the soil, making the anchoring effect of the anchor rod body better.
[0019] Preferably, a conical member is integrally formed at one end of the reinforcing member away from the expansion sleeve, and the end of the conical member away from the reinforcing member is a tip.
[0020] By adopting the above technical solution, when the anchor rod body expands and contracts due to the influence of thermal expansion and contraction in the formation, the expansion sleeve expands outward under the drive of the expansion member, thereby strengthening the connection strength between the anchor rod body and the formation soil through the expansion sleeve. The connection between the expansion sleeve and the formation soil is made rapid and effective through the reinforcing members on the circumferential side of the expansion sleeve. A conical member is added to the top of the reinforcing member, and the tip of the conical member faces the direction of the formation soil. The tip of the conical member can break open the soil surface more quickly, enabling the reinforcing member to quickly enter the soil. After the reinforcing member enters the soil interior, it acts on the soil together with the conical member at its top.
[0021] Specifically, during the expansion process of the expansion sleeve, the tip of the conical member penetrates deeper into the soil as the expansion sleeve gradually expands. After the reinforcing member enters the soil along with the conical member, it squeezes the surrounding soil, thereby expanding the space inside the soil. Furthermore, under the combined action of the conical member and the reinforcing member, the space inside the soil can be quickly and effectively expanded to allow the periphery of the expansion sleeve to enter. Moreover, through the conical member and the reinforcing member, not only can the expansion sleeve be quickly and effectively combined with the deep soil, but also the combination between the expansion sleeve and the surrounding soil can be strengthened during the continuous combination process. This is conducive to further enhancing the tightness of the connection between the expansion sleeve and the formation soil, thereby effectively ensuring the stability of the anchor rod body during long-term anchoring in the formation.
[0022] Preferably, clamping plates are integrally formed on both the left and right sides of the conical member, and the clamping plates are used to clamp the conical member into the soil.
[0023] By adopting the above technical solution, the clamping plates can firmly clamp the conical member in the soil after the conical member penetrates into the soil, thereby effectively avoiding the problem that the conical member falls out of the soil after penetrating into the soil. Furthermore, through the clamping plates, the stability of the connection between the conical member and the formation soil can be effectively strengthened, thereby effectively ensuring the long-term anchoring effect of the anchor rod body in the formation.
[0024] Preferably, the clamping plate includes a first plate body and a second plate body. One end of the first plate body is connected to the conical member, and the other end of the first plate body is connected to the second plate body. The first plate body is integrally inclined, and the second plate body is also inclined. The end of the second plate body away from the first plate body is inclined in a direction away from the conical member.
[0025] By adopting the above technical solution, the first plate body and the second plate body are arranged in an inclined connection manner. After the first plate body and the second plate body penetrate into the soil, they can not only expand the space inside the soil, but also, when the expansion sleeve expands to the maximum value, at this time, the conical member stops further extending into the soil. In this state, the bottoms of the first plate body and the second plate body will be clamped in the soil, and due to the certain included angle between the first plate body and the second plate body, it is very difficult for the first plate body and the second plate body to fall out of the soil, thereby effectively ensuring that the conical member is firmly clamped in the soil, and thus effectively ensuring the long-term anchoring effect of the anchor rod body in the formation.
[0026] In summary, the present application includes at least one of the following beneficial technical effects:
[0027] 1. When the anchor rod undergoes thermal expansion and contraction in the formation, the connection between the anchor rod body and the formation soil is made tighter through the expansion member and the spray expansion sleeve. As a result, it can effectively prevent the anchor rod from being crushed by the surrounding soil, which is conducive to ensuring the long-term anchoring effect of the anchor rod body in the formation. When the anchor rod body expands and contracts due to thermal expansion and contraction in the formation, the upper and lower ends of the expansion member can quickly and effectively push the inner walls on both sides of the expansion sleeve away from each other, thereby adjusting the diameter of the expansion sleeve and enabling the two sides of the expansion sleeve to quickly combine with the surrounding soil. Then, the connection strength between the anchor rod body and the soil is effectively enhanced through the expansion sleeve.
[0028] Compared with the traditional anchor rod anchoring method, in this anchoring method, the anchor rod is set to be closely connected to the formation soil during the expansion and contraction process through the expansion member and the expansion sleeve. By adding stress points on the periphery of the anchor rod through the expansion member and the expansion sleeve, the anchor rod can be connected to the surrounding soil through these stress points during the expansion and contraction process. At the same time, during the process of effectively enhancing the connection strength between the anchor rod body and the formation soil through the expansion member and the expansion sleeve, the anchor rod body is not directly connected to the formation soil. This can effectively avoid the problem that the anchor rod body is in long-term friction with the soil during the process of being buried in the formation for a long time, resulting in cracks on the anchor rod body. Thus, the structural strength of the anchor rod body itself can be effectively guaranteed, and further the long-term anchoring effect of the anchor rod body in the formation can be ensured.
[0029] 2. When the anchor rod body expands and contracts due to thermal expansion and contraction in the formation, the expansion sleeve is tightly connected to the formation soil under the drive of the expansion member. During the expansion process of the expansion sleeve, the reinforcing member is affected by the expansion of the expansion sleeve and generates extrusion with the formation soil. By using the extrusion of the reinforcing member on the soil, the soil is broken open, so that the periphery of the expansion sleeve can smoothly enter the soil. Then, the connection between the expansion sleeve and the formation soil can be made more rapid and effective by using the reinforcing member. Therefore, when the anchor rod body expands and contracts, the reinforcing member can quickly connect the expansion sleeve and the soil tightly, so that the anchor rod body can be quickly and tightly connected to the soil. Quickly and effectively connecting the anchor rod body and the formation soil tightly can reduce the damage to the structure of the anchor rod body itself during the expansion and contraction process, and further ensure the long-term anchoring effect of the anchor rod body.
[0030] 3. During the expansion process of the expansion sleeve, the tip of the conical part penetrates deeper into the soil as the expansion sleeve gradually expands. After the reinforcement enters the soil with the conical part, it squeezes the surrounding soil, thereby expanding the space inside the soil. Furthermore, under the combined action of the conical part and the reinforcement, the space inside the soil can be quickly and effectively expanded for the periphery of the expansion sleeve to enter. Thus, through the conical part and the reinforcement, not only can the expansion sleeve be quickly and effectively combined with the deep soil, but also the connection between the expansion sleeve and the surrounding soil can be strengthened while continuously combining. This is conducive to further enhancing the tightness of the connection between the expansion sleeve and the formation soil, thereby effectively ensuring the stability of the anchor rod body during long-term anchoring in the formation.

[0035] The following is a further detailed description of the present application in conjunction with the attached Figure 1 - attached Figure 3 drawings to further illustrate the present application.
[0036] Embodiment:
[0037] The embodiment of the present application discloses a two-way and double energy-absorbing anchor rod. Referring to Figure 1 and Figure 2 , it includes an anchor rod body 1 and an expansion assembly 2. The expansion assembly 2 includes an expansion part 21 and an expansion sleeve 22. The expansion sleeve 22 is sleeved on the periphery of the anchor rod body 1, and the expansion part 21 is sleeved between the anchor rod body 1 and the expansion sleeve 22, and both the upper and lower ends of the expansion part 21 are connected to the expansion sleeve 22. The expansion part 21 and the expansion sleeve 22 are used to enhance the connection strength between the anchor rod body 1 and the soil. When the anchor rod undergoes thermal expansion and contraction in the formation, through the expansion part 21 and the expansion sleeve 22, the connection between the anchor rod body 1 and the formation soil becomes tighter, thereby effectively preventing the anchor rod from being squeezed and broken by the surrounding soil, and thus being conducive to ensuring the long-term anchoring effect of the anchor rod body 1 in the formation.
[0038] Reference Figure 1 and Figure 2 In this embodiment, multiple sets of expansion components 2 are evenly arranged at intervals along the length direction of the anchor rod body 1. Through these expansion components 2, when the anchor rod body 1 expands and contracts in the formation, multiple different positions on the anchor rod body 1 can be closely connected to the soil of the formation. Thus, when the anchor rod body 1 expands and contracts, the connection between the anchor rod body 1 and the soil can be more uniform, and there will be no problem that the connection effect of some positions of the anchor rod body 1 with the soil is good while that of some positions is poor. Furthermore, the connection effect between the anchor rod body 1 and the formation soil can be further enhanced.
[0039] Specifically, referring to Figure 1 and Figure 2 the overall shape of the expansion member 21 is hexagonal. Both the left and right ends of the expansion member 21 are sleeved on the anchor rod body 1. At the same time, both the upper and lower ends of the expansion member 21 are connected to the inner wall of the expansion sleeve 22, and both the upper and lower ends of the expansion member 21 are in a "V"-shaped structure. This design makes both the left and right sides of the upper and lower ends of the expansion member 21 inclined, that is, both the end where the expansion member 21 is connected to the expansion sleeve 22 and the end where the expansion member 21 is connected to the anchor rod body 1 are inclined. With this design, when the anchor rod body 1 expands and contracts due to thermal expansion and contraction in the formation, the upper and lower ends of the expansion member 21 can quickly and effectively push the inner walls of the upper and lower sides of the expansion sleeve 22 away from each other, thereby adjusting the diameter of the expansion sleeve 22, enabling the upper and lower sides of the expansion sleeve 22 to quickly combine with the surrounding soil, and further effectively strengthening the connection strength between the anchor rod body 1 and the soil through the expansion sleeve 22.
[0040] Compared with the traditional anchor rod anchoring method, this anchoring method makes the anchor rod closely connected to the soil of the formation during the expansion and contraction process through the expansion member 21 and the expansion sleeve 22, and increases the stress points on the periphery of the anchor rod through the expansion member 21 and the expansion sleeve 22, enabling the anchor rod to be connected to the surrounding soil through these stress points during the expansion and contraction process. At the same time, during the process of effectively strengthening the connection strength between the anchor rod body 1 and the formation soil through the expansion member 21 and the expansion sleeve 22, the anchor rod body 1 is not directly connected to the soil of the formation. This can effectively avoid the problem that the anchor rod body 1 has cracks due to long-term friction with the soil during the process of being buried in the formation for a long time, thereby effectively ensuring the structural strength of the anchor rod body 1 itself and further ensuring the effect of the anchor rod body 1 being anchored in the formation for a long time.
[0041] Furthermore, referring to Figure 1 and Figure 2, a telescopic spring 3 is sleeved on the periphery of the anchor rod body 1, and the telescopic spring 3 is located between the expansion sleeve 22 and the anchor rod body 1. When the anchor rod body 1 expands and contracts due to thermal expansion and contraction in the formation, the telescopic spring 3 can effectively buffer and reset the anchor rod body 1 during the expansion and contraction process of the anchor rod body 1. By using the telescopic spring 3 to buffer the expansion of the anchor rod body 1, it can effectively prevent the anchor rod body 1 from being damaged structurally due to excessive thermal expansion. At the same time, during the cold contraction process of the anchor rod body 1, it can drive the anchor rod body 1 to contract, thereby effectively accelerating the contraction efficiency of the anchoring body.
[0042] Furthermore, referring to Figure 1 and Figure 2 , a reinforcing member 4 is integrally added to the outer periphery of the expansion sleeve 22. The reinforcing member 4 is annular. When the anchor rod body 1 expands and contracts due to thermal expansion and contraction in the formation, the expansion sleeve 22 is tightly connected to the soil of the formation through the drive of the expansion member 21. During the expansion process of the expansion sleeve 22, the reinforcing member 4 is affected by the expansion of the expansion sleeve 22 and generates extrusion with the soil of the formation. By using the extrusion of the reinforcing member 4 on the soil, the soil is broken, so that the periphery of the expansion sleeve 22 can smoothly enter the soil. Furthermore, by using the reinforcing member 4, the connection between the expansion sleeve 22 and the formation soil can be made faster and more effective. Therefore, when the anchor rod body 1 expands and contracts, the reinforcing member 4 can quickly connect the expansion sleeve 22 tightly with the soil, so that the anchor rod body 1 can be quickly and tightly connected to the soil. Quickly and effectively connecting the anchor rod body 1 tightly to the formation soil can reduce the damage to its own structure during the expansion and contraction process of the anchor rod body 1, and further ensure the long-term anchoring effect of the anchor rod body 1.
[0043] In this embodiment, multiple reinforcing members 4 are provided, and the multiple reinforcing members 4 are evenly distributed at intervals along the length direction of the expansion sleeve 22. By using these reinforcing members 4, it can effectively ensure that different positions of the anchor rod body 1 are quickly and effectively combined with the soil, making the anchoring effect of the anchor rod body 1 better.
[0044] Furthermore, referring to Figure 2 and Figure 3, a conical part 5 is integrally formed at one end of the reinforcing member 4 away from the expansion sleeve 22. The conical part 5 is in a conical shape as a whole, and the end of the conical part 5 away from the reinforcing member 4 is a tip. When the anchor rod body 1 expands and contracts under the influence of thermal expansion and contraction in the formation, the expansion sleeve 22 expands outward under the drive of the expansion part 21, so as to strengthen the connection strength between the anchor rod body 1 and the formation soil through the expansion sleeve 22. The connection between the expansion sleeve 22 and the formation soil enables the connection between the expansion sleeve 22 and the formation soil to be rapid and effective through the reinforcing member 4 on the circumferential side of the expansion sleeve 22. A conical part 5 is added on the top of the reinforcing member 4, and the tip of the conical part 5 faces the direction of the formation soil. The tip part of the conical part 5 can break open the soil surface more quickly, so that the reinforcing member 4 can quickly enter the soil. After the reinforcing member 4 enters the soil, it acts on the soil together with the conical part 5 on its top.
[0045] Specifically, referring to Figure 2 and Figure 3 , when the expansion sleeve 22 expands, the tip of the conical part 5 breaks into the soil deeper with the gradual expansion of the expansion sleeve 22. After the reinforcing member 4 enters the soil with the conical part 5, it squeezes the circumferential side of the soil, thereby expanding the space inside the soil. Furthermore, under the combined action of the conical part 5 and the reinforcing member 4, the space inside the soil can be quickly and effectively expanded for the circumferential side of the expansion sleeve 22 to enter. Furthermore, through the conical part 5 and the reinforcing member 4, not only can the expansion sleeve 22 be quickly and effectively combined with the deep soil, but also the combination between the expansion sleeve 22 and the circumferential side of the soil can be strengthened while continuously combining, which is beneficial to further strengthening the tightness of the connection between the expansion sleeve 22 and the formation soil, thereby effectively ensuring the stability of the long-term anchoring of the anchor rod body 1 in the formation.
[0046] Furthermore, referring to Figure 2 and Figure 3 , clamping plates 6 are integrally formed on both the left and right sides of the conical part 5. The clamping plates 6 can firmly clamp the conical part 5 in the soil after the conical part 5 breaks into the soil, thereby effectively avoiding the problem that the conical part 5 falls out of the soil after breaking into the soil. Furthermore, through the clamping plates 6, the stability of the connection between the conical part 5 and the formation soil can be effectively strengthened, thereby effectively ensuring the effect of the long-term anchoring of the anchor rod body 1 in the formation.
[0047] Specifically, referring to Figure 2 and Figure 3 , the clamping plate 6 includes a first plate body 61 and a second plate body 62. One end of the first plate body 61 is connected to the conical part 5, and the other end of the first plate body 61 is connected to the second plate body 62. The first plate body 61 is in an inclined shape as a whole, and the second plate body 62 is also in an inclined shape. The end of the second plate body 62 away from the first plate body 61 is inclined away from the conical part 5.
[0048] The first plate body 61 and the second plate body 62 are arranged in an inclined connection mode. After the first plate body 61 and the second plate body 62 penetrate into the soil, not only can the space inside the soil be enlarged, but also when the expansion sleeve 22 expands to the maximum value, at this time, the conical member 5 stops extending further into the soil. In this state, the bottoms of the first plate body 61 and the second plate body 62 will be stuck inside the soil, and due to the certain included angle between the first plate body 61 and the second plate body 62, it is very difficult for the first plate body 61 and the second plate body 62 to fall out of the soil, thereby effectively ensuring that the conical member 5 is firmly stuck inside the soil, and thus effectively ensuring the long-term anchoring effect of the anchor rod body 1 in the formation.
[0049] The implementation principle of a two-way and double energy-absorbing anchor rod in an embodiment of the present application is as follows:
[0050] When the anchor rod undergoes thermal expansion and contraction in the formation, the connection between the anchor rod body 1 and the formation soil is made closer through the expansion member 21 and the spray expansion sleeve 22, thereby effectively preventing the anchor rod from being squeezed and broken by the surrounding soil, and thus being beneficial to ensuring the long-term anchoring effect of the anchor rod body 1 in the formation.
[0051] Compared with the traditional anchor rod anchoring method, in this anchoring method, the anchor rod is set in a tightly connected state with the formation soil during the expansion and contraction process through the expansion member 21 and the expansion sleeve 22. By the expansion member 21 and the expansion sleeve 22, the stress points on the periphery of the anchor rod are increased, so that the anchor rod can be connected to the surrounding soil through these stress points during the expansion and contraction process. At the same time, in the process of effectively strengthening the connection strength between the anchor rod body 1 and the formation soil through the expansion member 21 and the expansion sleeve 22, the anchor rod body 1 is not directly connected to the formation soil, which can effectively avoid the problem that the anchor rod body 1 has cracks due to long-term friction with the soil during the long-term embedding process in the formation, and thus can effectively guarantee the structural strength of the anchor rod body 1 itself, and further guarantee the long-term anchoring effect of the anchor rod body 1 in the formation.
[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
