[0044] Reference Figure 1-10 The present invention provides a technical solution: a toughness tie device for preventing the dislocation of anti-slide piles for slope reinforcement under earthquake action, comprising: a cross cylinder section 2, which is placed in the anti-slide pile 1 and fixed by integral casting;

[0045] The reinforcing seat 3 is arranged on one end of the cross cylinder section 2 of the anti-sliding pile 1 away from the side of the slope;

[0046] The tensioning mechanism 4 includes an embedded end 7 for embedding in the sliding bed for tensioning, a straight pulling system 6 for straight pulling and tensioning the anti-slip pile 1, a side pulling system 8 for side pulling and tensioning the anti-slip pile 1, and a tough joint 5. One end of the tough joint 5 is used to tension the embedded end 7, and the other end is used to tension the straight pulling system 6 and the side pulling system 8. The tough joint is arranged in the sliding body; wherein, the tough joint, the embedded end and the anti-slip pile are relatively located on the same vertical plane, ensuring that the anti-slip pile can obtain a certain strength of tensioning and tightening strength, and the adjacent anti-slip piles are tensioned and connected by the side pulling system, and the side pulling system acts on the tough joint, so that the tension between the anti-slip piles and the vibration between the anti-slip piles and the sliding body can be transmitted to each other, and the tough joint is used to tension and absorb energy, thereby absorbing the instantaneous energy of the strong earthquake, avoiding excessive lateral tensioning stiffness of the anti-slip piles, and causing shear damage of the anti-slip piles.

[0047] In this embodiment, the tough joint 5 includes: a retaining tube 51, in which a first column cavity 511, a second column cavity 512, and a third column cavity 513 are sequentially provided from left to right. The outer periphery of the second column cavity 512 is further provided with a cutting cavity 5121 communicating therewith.

[0048] The energy absorbing component 9 is assembled in the cut cavity 5121 and the second column cavity 512;

[0049] The sliding column 83 slides in the column cavity 1 511, and one end thereof is connected to the bottom of the column cavity 1 via the energy absorbing spring 2 84;

[0050] The telescopic column 73 is connected to the second column cavity 512, and one end thereof is connected to the bottom of the second column cavity via an energy absorbing spring 1 74;

[0051] The energy absorbing assembly 9 includes: a hole plate 91 fixed in the column cavity 1 511 and used to connect the energy absorbing spring 2 84;

[0052] The disc 1 92 is fixed in the middle of the column cavity 2 512, and the left side of the disc is provided with a rotating shaft seat 1 921 corresponding to the cutting cavity;

[0053] The second disc 93 is fixed to the right side of the second column cavity 512, and the left side of the disc is provided with a second shaft seat 931 corresponding to the cutting cavity;

[0054] The conducting block 94 is rotatably mounted in the cutting cavity via a shaft 95. Its inner end is connected to one end of a tie rope 97, the other end of which passes around a first rotating shaft seat 921 and is connected to the tie slide 83. Furthermore, a clamping cavity is provided on the outer end of the conducting block 94. The clamping cavity is hingedly connected to one end of a connecting rod 96, the other end of which is hingedly connected to a second rotating shaft seat 931. In other words, the conducting block can be displaced with the retaining cylinder and can also be rotated by the action of the fourth tie rope and the connecting rod.

[0055] The straight-pull system 6 includes: a locking seat 61 fixed on the pulling seat 3 and arranged in a centrally symmetrical manner;

[0056] A pull rope 62, one end of which is connected to the left end of the tie-retaining cylinder 51 and the other end is connected to the tie-locking seat 61;

[0057] The side pulling system 8 includes: a second locking seat 81, fixed on the pulling seat 3, and arranged in a central symmetrical manner;

[0058] A pull rod 85, one end of which is connected to the second pull-locking seat 81 and the other end of which is fixed with a collar 86;

[0059] The fixed plate 21 is fixed on the side opening of the cross cylinder section 2;

[0060] A third pull rope 82, one end of which is connected to the tie-down slide 83, and the other end of which passes through the collar 86 and the fixed disk 21 on the same side of the collar and is connected to the fixed disk at the barrel opening of the adjacent cross barrel section on the same side of the tie-down collar;

[0061] Among them, the setting orientation of the locking seat 1 is mainly symmetrically distributed in the upper and lower directions, that is, the straight-pull system is a vertical tensioning anti-slip pile and a retaining cylinder in the toughness joint. Among them, if the tensioning mechanism is subjected to the force caused by a strong earthquake, and the intensity of the force transmitted to the conduction block is greater than the intensity of the force transmitted to the sliding column and / or the telescopic column, at this time, taking a momentary strong earthquake as an example, it will push the conduction block to rotate to the left and at the same time have a tendency to move to the left, which can cause the length of the pull rope 4 at the end of the axial area to increase instantaneously, and the sliding column and the pull rope 3 will have a tendency to retract to the left instantaneously, which can make the tensioning stiffness between adjacent anti-slip piles release energy instantaneously, thereby reducing the lateral tensioning stiffness of the anti-slip piles while still ensuring that they have a certain safety tensioning stiffness. degree, avoiding the anti-slip pile from suffering greater shear damage; wherein, as the conductive block performs the above-mentioned movement, it will prompt the pull rod to tighten the telescopic column, so that there is still a strong vertical surface between the pull rope 1 and the pull rope 2 to cope with the instantaneous energy of the strong earthquake. Therefore, it can ensure that when an instantaneous strong earthquake occurs, the lateral tie stiffness of the anti-slip pile is instantly reduced and the vertical tie stiffness is instantly enhanced. Moreover, with the repetitive fluctuations of the strong earthquake, the lateral and vertical tie stiffness can be effectively adapted and reset with the frequency of the strong earthquake, thereby ensuring that the toughness joint has a safe, reliable high-strength tie stiffness and toughness strength. At the same time, it can well cope with the instantaneous adjustment of the lateral tie stiffness of the anti-slip pile under the action of a strong earthquake, ensuring that the anti-slip pile can safely and effectively resist the sliding tendency of the sliding body.

[0062] In this embodiment, a rotating shaft is installed at the inner end of the conductive block 94, and the rotating shaft is connected and tied with the pull rope 4 97 to reduce the friction effect between the pull rope 4 and the conductive block.

[0063] In this embodiment, the conductive block 94 can be rotated clockwise to be tangent to the outer surface of the retaining tube, and the conductive block 94 can be rotated counterclockwise to protrude from the outer surface of the retaining tube; so as to facilitate the installation of the toughness joint and ensure the embedding strength of the sliding body.

[0064] In this embodiment, the embedded end 7 includes an embedded body 72 embedded in the interior of the slide bed, and the other end of the embedded body 72 is connected to the telescopic column 73 through a second pull rope 71.

[0065] In this embodiment, the outside of the left retaining cylinder and the outside of the right retaining cylinder of the conductive block 94 are respectively covered with telescopic cylinders 53 to prevent particles from falling into the cutting cavity when the conductive block moves, thereby ensuring the normal conductive activity of the conductive block.

[0066] In this embodiment, a telescopic cylinder 52 is respectively sleeved between the sliding column 83 and the left end of the retaining cylinder 51, and between the telescopic column 73 and the right end of the retaining cylinder to prevent the two ends of the tough joint from being stuck during telescoping.

Any technician familiar with this technical field, within the technical scope disclosed by the invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
