Application of Glass Fiber Reinforced Plastic Bars in Slope Protection

Abstract

Application of a glass fiber bar in slope protection. The glass fiber bar is used in slope protection, and an inclined inner reinforcement layer and a vertical outer reinforcement layer structure are used in slope protection to protect the slope of the slope body. A filler section is provided between the inner reinforcement layer and the outer reinforcement layer. The existence of this filler section enables the inner reinforcement layer to be compacted during slope body protection. Further, the present invention takes into account the problem that the slope inside the inner reinforcement layer protection may deform due to subsequent vibrations or other factors. A cable adjustment device with a dynamic adjustment pulley structure is used to actively compensate for this deformation through the action of the glass fiber cable, thereby improving the stress condition of the slope of the slope body. Although the filler section can compact the inner reinforcement layer, it will inevitably also have the problem of deformation. And this cable adjustment device can actively adjust this deformation, so that the double-layer slope protection structure of the present invention can provide good protection.

Description

Technical Field

[0001] The present invention belongs to the technical field of slope protection, and particularly relates to the application of glass fiber bars in slope protection. Background Art

[0002] With the gradual increase of expressways and the increasing number of large-scale key engineering projects, slope protection becomes particularly important. The existing slope protection is all carried out through anchor structures. However, in the existing slope protection, after the anchor is buried, it cannot adapt to the continuously dynamically changing landslide body, and there is only a single layer of protection for the slope, so the slope protection effect still needs to be improved. In the prior art, such as Patent Document 1, it discloses an environment-friendly slope reinforcement device for municipal engineering, which sets a fixed wall 3 at one end of the landslide body 5, and a fastening bolt 9 is arranged in the stable slope body 7, so that both ends of the fastening bolt 9 are respectively connected to the fixed wall 3 and the stable slope body 7, and the fixed wall 3 is tightened by the fastening bolt 9 to protect the slope. However, in this reinforcement device, it does not consider that the deformations of soil layers at different depths are different. When the landslide body 5 loosens and deforms due to rain or earthquake, it can only deform passively and cannot actively adjust the landslide body to a certain extent; another example is Patent Document 2, which discloses a soil nail wall support structure, which sets a number of resisting plates on the slope surface, and then sets a support device 2 at the bottom of the slope. The support device 2 is connected to the resisting plates through a pulley structure, and the resisting plates are pressed by adjusting the length of the support cross bar. However, these pressing plates act independently and cannot adjust the problem of different stresses at different heights of the slope, and it also belongs to a passive support method for adjusting the slope. Further, glass fiber bars have the advantages of high tensile strength, light self-weight, corrosion resistance and low cost, while the anchor structure used in slope protection mainly bears tensile force to play the role of slope protection.

[0003] [Patent Document 1] CN109930612B;

[0004] [Patent Document 2] CN112323818A.

[0005] In the prior art, for slope protection, glass fiber bars have not been applied thereto. Moreover, for slope protection, only passive protection methods have been mentioned or used, and none of them can make dynamic and active adjustments according to the different forces received at different depths of the slope, so the protection effect needs to be improved. At the same time, there is no slope protection that provides dual protection and the two layers of protection are interlocked with each other. Based on this, the present invention provides an application of glass fiber bars in slope protection. In this application, a double-layer slope protection device is used, and this protection device takes into account the different forces between soil layers at different depths. Based on this, when deformation occurs between soil layers, the stress received between soil layers can be adjusted to a certain extent, and glass fiber bars are used as tension members, which can withstand greater forces and make the slope more stable. Summary of the Invention

[0014] An application of glass fiber bars in slope protection. The slope protection includes a slope body, and the application includes the following steps:

[0015] A. Drive a bolt connected with a glass fiber reinforced plastic tendon rope at the slope of the slope body;

[0016] B. Set an inner reinforcement layer on the surface of the slope;

[0019] E. Wind the glass fiber reinforced plastic tendon rope around the rope adjusting device;

[0020] F. Set a filler section between the outer reinforcement layer and the inner reinforcement layer;

[0021] The rope adjusting device includes a rotating disc, a dynamic adjusting pulley, a protective shell and an adjusting rod. The rotating disc is rotatably arranged on the outer reinforcement layer. The dynamic adjusting pulley is rotatably arranged at both ends of the adjusting rod. The adjusting rod is fixedly arranged inside the two side walls of the protective shell. The outer reinforcement layer is rotatably arranged on the reinforcement layer foundation and can slide a certain distance in the horizontal direction relative to the reinforcement layer foundation. Two glass fiber reinforced plastic tendon ropes are wound around each dynamic adjusting wheel. One end of one glass fiber reinforced plastic tendon rope is fixed to the upper end of the rotating disc, then bypasses the lower side of the dynamic adjusting pulley, and finally is fixedly connected to a bolt. The other end of the other glass fiber reinforced plastic tendon rope is fixed to the lower end of the rotating disc, then bypasses the upper side of the dynamic adjusting pulley, and finally is fixedly connected to another bolt. The other bolt is on the upper side of one bolt. The dynamic adjusting pulley can change the wheel diameter to adjust the tension of the glass fiber reinforced plastic tendon rope. The adjusting rod can adjust the length, so as to adjust the distance of the dynamic adjusting pulley.

[0022] Preferably, the dynamic adjusting pulley includes an inner wheel and a plurality of outer wheel arcs. The outer wheel arcs are fixedly arranged on the outer circumference of the inner wheel through a guide sleeve. A spring is also arranged on the guide sleeve. Both ends of the spring are fixedly arranged on the inner wheel and the outer wheel arc respectively.

[0023] Preferably, the number of the outer wheel arcs is 4, 6, 8 or 12. The number of the springs and the guide sleeves is the same as that of the outer wheel arcs. A linkage mechanism is arranged between the inner wheel and the outer wheel arcs. The linkage mechanism includes a fixed shaft, an arc-shaped rod and an arc-shaped sleeve. The arc-shaped rod is fixedly arranged on the guide sleeve through the fixed shaft. Both ends of the arc-shaped sleeve are sleeved on the outside of the arc-shaped rod respectively, so that a plurality of outer wheel arcs can expand and contract synchronously.

[0024] Preferably, the spring is in a compressed state, so that the glass fiber reinforced plastic tendon rope bypassing the dynamic adjusting pulley can always be in a tightened state. At the same time, the dynamic adjusting pulley can also adjust and balance the slope stress at the two bolts in real time, and improve the stress condition of the slope of the slope body.

[0025] Preferably, a plurality of the guy rope adjusting devices are provided, and the guy rope adjusting devices are located at the same height of the outer reinforcement layer and arranged transversely along the outer reinforcement layer, so as to be able to adjust the stress of the entire slope body, and at the same time ensure that the outer reinforcement layer remains fixed and safe relative to the inner reinforcement layer.

[0026] Preferably, the reinforced layer foundation includes reinforcing bars and triangular bases. A rotating shaft is provided on the triangular bases, and a horizontal chute structure that can be cooperatively connected with the rotating shaft is provided at the bottom of the outer reinforcement layer, so as to ensure that the outer reinforcement layer can rotate around the rotating shaft and can also horizontally slide a certain distance relative to the triangular bases; through the degrees of freedom of rotation and horizontal sliding, the guy rope adjusting device can not only adjust the internal stress of the slope of the slope body through the glass fiber reinforced bar guy rope, but also adjust the stress generated by the filler section on the outer reinforcement layer, so that each stress can be released and adjusted.

[0027] Preferably, there is a certain distance between two adjacent protective shells, so as to enable the filler in the filler section to be smoothly filled into the lower ends of the outer reinforcement layer and the inner reinforcement layer;

[0028] Preferably, in order to actively adjust the tension in the glass fiber reinforced bar guy rope, the guide sleeve is a hydraulic drive cylinder structure, so as to be able to actively adjust the telescopic degree of the outer wheel arc through the hydraulic driving force and adjust the magnitude of the tension between the outer reinforcement layer and the inner reinforcement layer.

[0029] Preferably, a plurality of guy rope adjusting devices are provided, and the rotating discs of adjacent guy rope adjusting devices are fixedly connected. Through the interaction between the plurality of connected and fixed guy rope adjusting devices with pulleys, the stress in the slope body and the filler section is well adjusted, ensuring the safety protection of the slope body.

[0030] The beneficial effects of the present invention are as follows:

[0031] 1), The application of the glass fiber reinforced bar in slope protection realizes the active protection of the slope body. The protection structure includes a double protection structure, and the double protection structures are linked. Through the double protection structure, the slope body can be made safer, further ensuring the safety of slope protection. In the active protection structure, since it is considered that the acting forces of soil layers at different depths in the slope on the protection plate are different, the protection plate can be adjusted adaptively;

[0032] 2) In the protection structure of the present invention, glass fiber bars are used as the cable structure, making full use of the advantage that glass fiber bars have strong tensile capacity. The double protection structure includes an inner reinforcement layer and an outer reinforcement layer. The glass fiber bars are connected between the inner reinforcement layer and the outer reinforcement layer through a cable adjustment device. Through the filler section arranged between the inner reinforcement layer and the outer reinforcement layer, as well as the vertically arranged outer reinforcement layer and the inclined inner reinforcement layer, the filler section can compact the slope surface of the slope body 1, preventing the collapse of the slope body 1. At the same time, the collapse of the slope body 1 can also be transmitted to the outer reinforcement layer through the glass fiber bars and the cable adjustment device. The outer reinforcement layer, the glass fiber bars and the cable adjustment device can dynamically adjust the compaction or relaxation of the filler section, so as to actively feedback and adjust a certain collapse deformation of the slope body 1;

[0033] 3) At the same time, the cable adjustment device includes a dynamic adjustment pulley that can radially contract and deform. The dynamic adjustment pulley can deform according to the tightness of the cable, so that the cable can always be in a tightened state. Even if the inclined surface of the slope body 1 becomes loose, the dynamic adjustment pulley can collide, so that the cable can compensate for the loosening amount. At the same time, the tightened cable can drive the outer reinforcement layer 5 to approach the inner reinforcement layer 3, squeezing the internal filler section 7, and the squeezed filler section 7 can compact the inner reinforcement layer 3, so as to relieve the loosening of the inclined surface of the slope body 1, and thus achieve an effect of dynamic balance and action, so that the protection of the slope body 1 can achieve the purpose of active protection;

[0034] 4) Further, considering that the filler section located in the outer reinforcement layer and the inner reinforcement layer may also have problems such as collapse or uneven stress distribution, the glass fiber cable 4 passes through the dynamic adjustment pulley and is wound and fixed on the slope body 1 at a higher position, while another glass fiber cable passes through the dynamic adjustment pulley and is wound and fixed on the slope body 1 at a lower position. Moreover, the outer reinforcement layer 5 is arranged on the triangular base through a rotating shaft. When the filler section deforms, it will drive the outer reinforcement layer 5 to rotate, and the outer reinforcement layer 5 can have a certain lateral displacement space in the horizontal direction. At this time, if the internal stress of the upper section of the filler section becomes larger, the outer reinforcement layer 5 makes a certain counterclockwise deflection around the axis of the turntable 9. At this time, the counterclockwise rotating turntable 9 drives the glass fiber cable 4 located below the dynamic adjustment pulley to tighten, and the other glass fiber cable 4 is in a relaxed state. At this time, it also makes the outer reinforcement layer 5 tend to rotate clockwise, so as to dynamically adjust the internal stress of the filler section and achieve the purpose of automatically adjusting the internal stress;

[0035] 5) Further, in order to ensure the effect of slope protection, a number of cable adjustment devices are horizontally distributed along the same height of the outer reinforcement layer 5. Considering that the stress on the slope body 1 is different at different heights and the force is uneven at different positions at the same height, in view of this situation, at least two dynamic adjustment pulleys are arranged vertically on the cable adjustment device, and an adjustment rod is also arranged between the dynamic adjustment pulleys. Each glass fiber tendon cable is fixedly arranged on the same rotating disk. Through the cable adjustment device arranged in this way, the internal stress on the slope surface of the slope body 1 can be released, making the internal stress balanced everywhere, reducing the risk of slope collapse. At the same time, when the internal stress is different in the filling section and the outer reinforcement layer 5 rotates counterclockwise, the adjustment rod 21 elongates, so that the glass fiber tendon is in a taut state, and the outer reinforcement layer 5 is adjusted back to its original position, thereby ensuring the safe operation of the internal reinforcement layer and the outer reinforcement layer.

[0060] As Figure 3, which is the second embodiment of the present invention. The slope protection includes a slope body 1, and the application includes the following steps:

[0061] A. Drive a bolt 2 connected with a glass fiber reinforced plastic tendon rope 4 into the slope of the slope body 1;

[0062] B. Set an inner reinforcement layer 3 on the surface of the slope;

[0063] C. Set an outer reinforcement layer 5 at a certain distance away from the slope;

[0064] D. Set a rope adjusting device 8 between the inner reinforcement layer 3 and the outer reinforcement layer 5;

[0065] E. Wind the glass fiber reinforced plastic tendon rope 4 around the rope adjusting device 8;

[0066] F. Set a filler section 7 between the outer reinforcement layer 5 and the inner reinforcement layer 3;

[0067] The rope adjusting device 8 includes a rotating disc 24, a dynamic adjusting pulley 10, a protective housing 11 and an adjusting rod 21. The rotating disc 24 is rotatably arranged on the outer reinforcement layer 5. The dynamic adjusting pulley 10 is rotatably arranged at both ends of the adjusting rod 21. The adjusting rod 21 is fixedly arranged inside the two side walls of the protective housing 11 (not shown in the figure). The outer reinforcement layer 5 is rotatably arranged on the reinforcement layer foundation 6 and can slide a certain distance in the horizontal direction relative to the reinforcement layer foundation 6. Two glass fiber reinforced plastic tendon ropes 4 are wound around each dynamic adjusting wheel. One end of one glass fiber reinforced plastic tendon rope 4 is fixed to the upper end of the rotating disc 24, then passes around the lower side of the dynamic adjusting pulley 10, and finally is fixedly connected to a bolt 2. The other end of the other glass fiber reinforced plastic tendon rope 4 is fixed to the lower end of the rotating disc 24, then passes around the upper side of the dynamic adjusting pulley 10, and finally is fixedly connected to another bolt 2. The other bolt 2 is on the upper side of the one bolt 2. The dynamic adjusting pulley 10 can change the wheel diameter to adjust the tension of the glass fiber reinforced plastic tendon rope 4. The adjusting rod 21 can adjust the length, so as to adjust the distance of the dynamic adjusting pulley 10.

[0068] Preferably, a plurality of rope adjusting devices 8 are provided. The rotating discs 24 of adjacent rope adjusting devices 8 are fixedly connected. Through the interaction between the plurality of connected and fixed rope adjusting devices 8 with pulleys, the stress in the slope body and the filler section can be well adjusted to ensure the correct protection of the slope body.

[0069] Preferably, the adjusting rod 21 is of a hydraulic telescopic cylinder structure;

[0070] Preferably, the dynamic adjustment pulley 10 and the adjustment rod 21 in the drawstring adjustment device 8 are reusable structures. When the outer reinforcement layer 5 needs to be replaced due to long service time, the dynamic adjustment pulley 10 and the adjustment rod 21 are reusable structures, which can reduce the use cost and improve the economic benefits.

[0071] Preferably, the protective shell 11 is fixedly arranged between the outer reinforcement layer 5 and the inner reinforcement layer 3. For example, it can be fixedly arranged on the inner reinforcement layer 3. The protective shell 11 forms a relatively enclosed space, which can ensure that the glass fiber tendon drawstring 4 is in a relatively independent working space, not interfered by the external filler or soil, and at the same time, it can also make the glass fiber tendon drawstring in a free movement state, making the slope protection effect better.

[0072] In order to enable those skilled in the art to understand the present application in detail, the application of the glass fiber tendon in slope protection is described as follows: When using the glass fiber tendon for slope protection in the present application, first, the anchor rod 2 connected with the glass fiber tendon drawstring 4 is inserted into the slope 1, then the inner reinforcement layer 3 is set on the slope of the slope 1, and at the same time, an outer reinforcement layer 5 that can rotate and make a certain lateral sliding movement is set at a certain distance from the inner reinforcement layer 3. Then the glass fiber tendon drawstring 4 is set between the outer reinforcement layer 5 and the inner reinforcement layer 3, and at the same time, a filler is added between the outer reinforcement layer 5 and the inner reinforcement layer 3 to form a filler section 7. At the same time, the glass fiber tendon drawstring 4 is fixed between the outer reinforcement layer 5 and the inner reinforcement layer 3 through the drawstring adjustment device. Due to the existence of the outer reinforcement layer and the filler section 7, it can compact the inner reinforcement layer 3 and prevent the slope 1 from collapsing. At the same time, since the glass fiber tendon drawstring 4 is wound through the dynamic adjustment pulley, when the internal stresses or deformations at different anchor rods 2 in the slope 1 are different, the glass fiber tendon drawstring 4 can automatically adapt to the change and be adjusted through the dynamic adjustment pulley, so as to adapt to the complex stress changes on the slope of the slope 1. At the same time, when the filler in the filler section 7 slips or deforms, the outer reinforcement layer 5 will feel the change and rotate counterclockwise, and the glass fiber tendon drawstring 4 wound under the dynamic adjustment pulley 10 will be tightened, and the glass fiber tendon drawstring 4 wound above the dynamic adjustment pulley 10 will be loosened. As a whole, the tension of the glass fiber tendon drawstring 4 received by the filler in the lower end of the filler section 7 is less than that in the upper end, so that the outer reinforcement layer 5 forms a clockwise movement trend, so as to automatically perform dynamic adjustment to adapt to the filler section 7. Further, if the spring 14 of the dynamic adjustment pulley 10 still cannot be adjusted well, at this time, start the elongation adjustment of the guide sleeve 13 or the adjustment rod 21 to actively adjust the stress in the slope 1 and the filler section 7.

[0073] Although the present invention has been disclosed above in preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes, without departing from the scope of the technical solution of the present invention. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the technical solution of the present invention.
