Description

Technical Field

[0001] The present invention relates to the technical field of slope protection, in particular to a toughness tie device for a slope protection wall. Background Art

[0002] Slope support is an important engineering technology that is used in many construction and infrastructure projects. It is well known that in construction and infrastructure projects, slope stability is crucial. If the slope is unstable, it may cause soil erosion and even cause landslides. Therefore, slope support is needed to improve the stability of the slope. Currently, the commonly used slope support methods include protective net support and protective wall support.

[0003] The main support for the protective wall is to build a wall at the slope, and use the wall to provide stable support for the slope to prevent landslides. However, in most current projects, the slope protective wall is only built alone at the slope, which is prone to deformation and collapse. The root cause of this situation is: when the slope is formed, blasting or excavation is usually required to form a slope, and the slope is prone to faults due to the lack of external support. The connection between the fault and the stable stratum far away from the side of the protective wall is not strong. After the slope protective wall is built, the slope protective wall is in direct contact with the fault. In fact, the slope protective wall is in the active area of ​​the fault. When the fault is active or an earthquake occurs, the fault will exert a certain force on the protective wall. Especially when an earthquake occurs, the earthquake will give the fault an additional external force to make it move. The structure of the protective wall itself will be affected by the movement force of the fault and is prone to deformation and collapse.

[0004] Therefore, people are in urgent need of a slope protection wall toughness tie device that has good protection effect on the protection wall and increases the service life of the protection wall. Summary of the Invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The purpose of the present invention is to provide a tough anchoring device for a slope protection wall to solve the problems existing in the prior art. A buffer structure spanning the fault is set between the protection wall and the stable stratum, which can effectively alleviate the force exerted by the fault on the protection wall, improve the protection effect of the protection wall, and thereby increase the service life of the protection wall.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please refer to Figures 1 to 5 As shown, a toughness tie device for a slope protection wall is provided, comprising a first anchor 1, a second anchor 2 and a first tie spring 3. The first anchor 1 is fixed to a stable stratum by cement pouring or fastening with fasteners such as bolts, and the second anchor 2 is fixed to the slope protection wall by cement pouring or fastening with fasteners such as bolts. A mounting seat 5 is provided on both the first anchor 1 and the second anchor 2. One end of the first tie spring 3 is fixedly connected to the mounting seat 5 on the first anchor 1, and the other end is fixed to the mounting seat 5 on the second anchor 2. connected to form a buffer structure across the fault; in actual use, the first anchor 1 is fixed on the stable stratum, and the second anchor 2 is fixed on the slope protection wall. At this time, the first tie spring 3 can play the role of elastic buffer. When the slope protection wall is deformed due to the force generated by the fault movement or earthquake, the first tie spring 3 can effectively absorb the force that causes the slope protection wall to deform, reduce the deformation of the slope protection wall, protect the slope protection wall, prevent collapse caused by large deformation, and increase the service life of the slope protection wall.

[0029] Since the force generated by fault movement or earthquake is not only the force perpendicular to the slope protection wall, but also includes the force along the extension direction of the slope protection wall, this force may cause misalignment between the first anchor 1 and the second anchor 2. In the case of misalignment, it is easy to cause deformation or fracture at the connection between the first tie spring 3 and the mounting seat 5. For this reason, an elastic seat 6 with elastic self-recovery ability is provided on the mounting seat 5. Specifically, it is a rubber elastic seat 6. The first tie spring 3 is fixedly connected to the mounting seat 5 through the elastic seat 6. Specifically, the first tie spring 3 can be built in the elastic seat 6 by casting. By utilizing the elasticity of the elastic seat 6 itself, the connection between the first tie spring 3 and the mounting seat 5 can be protected to improve its service life. Moreover, the elastic seat 6 itself can also absorb energy when the first tie spring 3 is stretched or shortened, and cooperate with the first tie spring 3 to improve the buffering effect.

[0030] The elastic seat 6 is preferably a truncated cone structure. Compared with a cylindrical structure, its beveled edge can effectively increase its load.

[0031] Four second tie springs 4 are fixedly connected between the mounting seat 5 of the first anchor 1 and the mounting seat 5 of the second anchor 2. The four second tie springs 4 are evenly wound around the first tie spring 3. The second tie springs 4 can be directly welded to the mounting seat 5. The setting of the second tie springs 4 can serve as an auxiliary to improve the buffering effect of the overall device, thereby improving the protection effect of the slope protection wall, and can improve the extension and deformation recovery ability of the tie structure between the two first anchors 1 and the second anchors 2.

[0032] The pitch of the second tie spring 4 is set to be smaller than the pitch of the first tie spring 3, the cross-sectional circular diameter of the second tie spring 4 is smaller than the cross-sectional circular diameter of the first tie spring 3, the number of turns of the second tie spring 4 is greater than the number of turns of the first tie spring 3, and the elastic coefficient of the second tie spring 4 is greater than the elastic coefficient of the first tie spring 3. When the first anchor 1 and the second anchor 2 are misaligned, the deformation of the second tie spring 4 is smaller than that of the first tie spring 3. When the misalignment movement is more intense, multiple second tie springs 4 can still ensure the normal use of the device.

[0033] A fixing seat 7 is provided on the side of the first anchor 1 away from the second anchor 2, and a reset spring 8 is provided between the fixing seat 7 and the first anchor 1. The fixing seat 7 can increase the contact area between the first anchor 1 and the installation position, improve the connection effect, and thereby improve the stability of the device and the installation position. The elastic coefficient and strength of the reset spring 8 are set to be greater than those of the first tie spring 3 and the second tie spring 4, which can be used to further enhance the ability of the device to adjust and relieve the tension on the protective wall during fault activity or earthquake. Moreover, the elastic coefficient is set in a stepped manner. When the spring is damaged, it will first cause local damage instead of large-scale damage, which is convenient for maintenance by the staff.

[0034] The fixed seat 7 or the end face of the first anchor 1 close to the second anchor 2 is provided with a plurality of sliding grooves 9, and the sliding grooves 9 are arranged along the radial direction of the first tension spring 3. In this embodiment, the sliding grooves 9 are arranged on the fixed seat 7, and four sliding grooves 9 are arranged. The four sliding grooves 9 are uniformly divergent outward with the first tension spring 3 as the center. Four connecting components are evenly arranged around the mounting seat 5, and the connecting components include a supporting main rod 10, a supporting auxiliary rod 11 and a movable rod 12. One end of the supporting main rod 10 is hinged to the second anchor 2, and the other end is hinged to the supporting auxiliary rod 11. The supporting auxiliary rod 11 is slidingly arranged in the sliding groove 9 at one end away from the supporting main rod 10. The supporting auxiliary rod 11 mainly provides movable support for the supporting main rod 10. A movable rod 12 is hinged on the first anchor 1, and the movable rod 12 is located at the supporting auxiliary rod 1 1, a strip hole 17 matching the width of the movable rod 12 is provided on the inner side of the supporting main rod 10, and the end of the movable rod 12 away from the first anchor 1 passes through the strip hole 17 and is connected with the anti-detachment part 13 that prevents the movable rod 12 from escaping from the strip hole 17. The movable rod 12 is slidably arranged in the strip hole 17. The movable rod 12 has friction when moving in the strip hole 17. When movement occurs, friction consumes energy. The articulated motion planes between the supporting main rod 10 and the second anchor 2, between the supporting main rod 10 and the supporting auxiliary rod 11, and between the movable rod 12 and the first anchor 1 are arranged along the radial direction of the first tension spring 3. The arrangement of the connecting component can be used to enhance the structural strength of the device while ensuring the normal use of the device, so that the overall structure of the device is more stable and not prone to damage when in use.

[0035] The anti-slip portion 13 is cylindrical and perpendicular to the movable rod 12 . The anti-slip portion 13 can be integrally formed or welded with the movable rod 12 . The axial length of the anti-slip portion 13 is greater than the width of the strip hole 17 .

[0036] The end of the supporting auxiliary rod 11 close to the sliding groove 9 is spherical, and the cross-section of the sliding groove 9 is an arc shape with a central angle greater than 180° that matches the spherical shape of the end of the supporting auxiliary rod 11. A return spring 14 is arranged in the sliding groove 9. One end of the return spring 14 is connected to the supporting auxiliary rod 11, and the other end is connected to the inner wall of the sliding groove 9 away from the first tie spring 3. Through the setting of the return spring 14, the supporting auxiliary rod 11 can support and buffer the end of the supporting main rod 10 during fault activity and earthquakes.

[0037] Four buffer platforms 15 with elastic self-recovery capabilities are arranged around the mounting seat 5 of the first anchor 1 and the mounting seat 5 of the second anchor 2. The buffer platform 15 is a rubber buffer platform 15. A U-shaped connecting seat 16 is provided on the buffer platform 15. The supporting main rod 10 and the movable rod 12 are respectively hinged to the U-shaped connecting seat 16. The buffer platform 15 can support and buffer the movable rod 12.
