Description

Technical Field

[0001] This invention belongs to the field of geological fissure reinforcement technology, specifically a high-liquefaction geological fissure reinforcement structure. Background Technology

[0002] Soil liquefaction refers to the mechanical process by which saturated silty sand or light clay loses its strength instantaneously under earthquake action, changing from a solid to a liquid state. It is a type of earthquake-induced geological hazard. Essentially, it is caused by an increase in pore water pressure leading to the loss of shear strength in the sand. It is often accompanied by water jetting and sand eruption. High permeability is a key physical characteristic of liquefaction. Reinforcement typically employs structural reinforcement methods such as anchor bolts and supports.

[0003] Meanwhile, application number CN115125873B describes a bridge crack reinforcement structure, belonging to the field of bridge construction technology. The bridge crack reinforcement structure includes a reinforcement plate for bolted connection to the crack. The reinforcement plate has pouring holes. An installation block is slidably disposed within the reinforcement plate, with the sliding direction of the installation block parallel to the length direction of the crack. A rotating rod is rotatably disposed on the installation block, with the rotation axis of the rotating rod perpendicular to the plane of the reinforcement plate. The rotating rod extends beyond the reinforcement plate into the crack. An eccentric wheel is sleeved on one end of the rotating rod located within the crack. A vibrating rod is rotatably sleeved on the rotating rod, with the eccentric wheel located within the vibrating rod. A sliding assembly for driving the installation block to move is disposed within the reinforcement plate, and a rotating component for driving the rotating rod to rotate is disposed on the reinforcement plate. During use, the aforementioned crack reinforcement structure relies solely on anchor bolts for rigid fixation. However, due to liquefaction issues, crack slopes in highly liquefiable geological conditions experience soil erosion and surface crack expansion. After the anchor bolts are fixed, the reinforcement plate settles, causing the fixing position of the crack slope to shift and thus failing to effectively reinforce the crack slope.

[0004] Therefore, a reinforcement structure for high-liquefaction geological fractures is proposed to address the above problems. Summary of the Invention

[0005] To address the issue of displacement mentioned in the background section, this invention provides a high-liquefaction geological fissure reinforcement structure. This structure has the advantage of being able to utilize the elastic deformation effect of flexible rubber rods to hold the soil on the fissure slope firmly in the event of soil erosion on the fissure slope, thus preventing significant displacement of the reinforcement plate.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-liquefaction geological fissure reinforcement structure, including a reinforcement plate, side frames fixedly provided on both the left and right sides of the reinforcement plate, and a vertical beam support assembly provided on the outer side of the reinforcement plate; The vertical beam support assembly includes vertical beams fixed to the reinforcing plate, and a pre-tightening assembly is provided between adjacent vertical beams; The pretensioning assembly includes a support rod, a pretensioning steel bar is slidably provided inside the support rod, anti-detachment frames are fixed at both ends of the pretensioning steel bar, a positioning seat that fits against the vertical beam is provided on the outside of the anti-detachment frame, and an anchoring assembly is provided through the inside of the side frame; The anchoring assembly includes anchor rods that pass through the four corners of the side frame, with a screw screw screwed inside one end of each anchor rod, a flexible rubber rod passing through the middle of the side frame, and an anti-settlement assembly passing through the middle of the reinforcing plate. The anti-settlement component includes a square column that penetrates the reinforcing plate and is fixed thereto. The square column has a screw rod three spirally arranged inside. The bottom of the screw rod three is rotatably provided with a rotating column. The other end of the rotating column is fixedly provided with a base, and the base is in contact with the reinforcing plate.

[0007] The above technical solution serves as the core load-bearing foundation, absorbing the forces of each component, directly fitting into the crack area, preventing crack expansion, and providing a stable installation benchmark for the overall reinforced structure. The side frame connects the reinforcement plate and the anchoring components, widening the stress range, enhancing the lateral support of the structure, and preventing unilateral stress imbalance of the reinforcement plate.

[0008] Preferably, a gasket is fitted on the outer side of the screw, and the gasket fits against the side frame.

[0009] Through the above technical solution, the anchor rod and screw, together with the washer, achieve rigid anchoring, while the flexible rubber rod, together with the anti-detachment block, wire coil, and hole-expanding rod, form a flexible and adaptable anchoring. The combination of rigidity and flexibility not only improves pull-out resistance but also adapts to ground deformation and prevents structural displacement. Preferably, an anti-detachment block is fixedly provided on the outer side of the flexible rubber rod, and the anti-detachment block is triangular in shape. An insertion hole is opened on the surface of the flexible rubber rod, and an iron wire coil is inserted into the interior of the adjacent insertion hole.

[0010] The above technical solution facilitates the rapid positioning and retraction of the flexible rubber rod.

[0011] Preferably, one end of the flexible rubber rod is rounded, and the other end of the flexible rubber rod has an extrusion hole, into which an expansion rod is inserted.

[0012] Preferably, the top end of the screw three is abutted against the screw two, which is spirally arranged with the square column, and the top end of the screw three is provided with a cross-shaped groove.

[0013] Through the above technical solution, the spiral linkage of the square column, screw two and screw three can flexibly adjust the unfolding state of the base, expand the contact area with the stratum, disperse the load, and alleviate the uneven settlement of highly liquefied geology.

[0014] Preferably, the vertical beam is shaped like a frustum and has slots on both sides, with buckles inside the slots for fixing to the positioning seat.

[0015] Through the above technical solution, the frustum-shaped vertical beam, combined with the interlocking structure of slots and buckles, quickly forms a longitudinal support frame, disperses the lateral pressure of liquefied strata, and improves the structure's resistance to deformation.

[0016] Preferably, the positioning seat has a slot inside, and the anti-dislodgement bracket is located inside the slot.

[0017] Preferably, a support slider is slidably provided inside the vertical groove of the support rod, and the support slider is attached to the bottom of the prestressed steel bar, and a corresponding arc groove is provided at the top. The prestressed steel bar is a telescopic steel sleeve. A damping rod is rotatably provided at the bottom end of the support slider. A spring is fixedly provided on the outside of the damping rod, and a spring sleeved with the damping rod is attached to the surface of the spring.

[0018] Through the above technical solutions, the telescopic prestressed steel bars, together with the support slider, damping rod and spring, apply continuous prestress, eliminate component gaps, buffer ground vibration, enhance the structural synergistic stress effect, and improve long-term stability; the guide frame and limit block ensure smooth component operation and reliable positioning.

[0019] Preferably, a positioning plate is fixedly provided at the bottom end of the support rod, a positioning pin is provided through the end of the positioning plate, a slot is provided on the surface of the positioning pin, and a limiting block is provided inside the slot of the positioning pin to be fixed to the damping rod, and one corner of the limiting block is rounded.

[0020] Preferably, a guide frame is fixedly provided on the outer side of the support slider, and two guide grooves are provided on the inner wall, with the guide frame slidingly disposed inside the guide groove of the support rod.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention utilizes a flexible rubber rod design to fix a reinforcing plate to a slope crack in conjunction with anchor rods, providing a flexible fixing structure. In cases of soil erosion on cracked slopes, the elastic deformation of the flexible rubber rod helps to hold the soil firmly, preventing significant displacement of the reinforcing plate. In highly liquefiable geological conditions, this component, through its anchor body, penetrates deep into stable strata. Combined with the locking structure of the anti-detachment block, it establishes a reliable connection between the reinforcing structure and the deep strata, significantly improving overall pull-out resistance and anti-slip capability. This solves the problem of liquefaction layers easily causing the reinforcing structure to float and shift. Furthermore, the design of the insertion hole and pin facilitates rapid on-site installation and positioning, adapting to the emergency operation requirements of crack reinforcement, while also enhancing the shear strength of the anchoring node, further ensuring the reliability of the connection between the structure and the strata.

[0022] 2. This invention, through the design of the screw three and base structure in the anti-settlement component, allows for adjustment of the base height. Supporting the bottom of the crack, it supports the upper reinforcement plate. Even after settlement occurs, the screw three can be rotated to push the base structure outward, maintaining a stable support effect. Addressing the risk of uneven settlement in highly liquefied geological formations, this component expands the contact area with the stratum using the base, evenly distributing the upper load to the liquefied layer, reducing localized stress disturbance to the stratum, and mitigating settlement differences. Simultaneously, its structure adapts to the rheological characteristics of the liquefied layer, absorbing ground displacement through its own minor deformation in the early stages of settlement, preventing cracking of the reinforcement structure due to differential settlement, maintaining long-term vertical stability in the crack area, and reducing later maintenance costs.

[0023] 3. This invention, through its vertical beam support component, addresses the issue of easily expanding fractures in highly liquefiable geological formations. This component, combined with a reinforcing plate, forms a longitudinal support system that effectively disperses the lateral compressive stress of the liquefiable strata, directly acting on weak points in the fracture area and limiting the lateral and longitudinal expansion of the fractures. Simultaneously, its structure adapts to the rheological characteristics of highly liquefiable geology, adaptively adjusting the distribution of support force with minor formation deformations, avoiding reinforcement failure caused by localized stress concentration, and improving the short-term support stability of the fracture area. 4. This invention, through its pre-tightening components, applies pre-tightening force to each reinforced component, eliminating assembly gaps between components and creating a synergistic force-bearing system for the vertical beams, anchors, and other components. This prevents components from loosening due to vibration loads in highly liquefied geological conditions. Simultaneously, the adjustable pre-tightening force can adapt to the reinforcement needs of geological conditions with varying degrees of liquefaction, forming a continuous constrained stress field in the crack area, inhibiting secondary crack propagation, improving the overall stiffness and fatigue resistance of the reinforced structure, and ensuring the stability of the long-term reinforcement effect.

[0031] The top of screw 3 53 is fitted with screw 2 52, which is spirally arranged with square column 51. The top of screw 3 53 has a cross-shaped groove. Tightening screw 2 52 fixes screw 3 53. Rotating screw 3 53 through the cross-shaped groove drives rotating column 54 to make base 55 fit against reinforcing plate 1, expanding the contact area with the ground and completing the anti-sinking structure arrangement.

[0032] The vertical beam 31 is shaped like a frustum, and slots 32 are provided on both sides of the vertical beam 31.

The guide frame 66 slides to support the reinforcing bar, and the damping rod 64 works with the spring 67 to buffer the ground vibration; the positioning pin 63 is inserted into the positioning plate 62, and the limiting block 68 is inserted into the slot of the positioning pin 63, and a pre-tightening force is applied to make the components fit tightly together.

[0034] The working principle of the technical solution provided by this invention: First, the slope of the high-liquefaction geological fissure is flushed and cleaned. The reinforcement plate 1 is then firmly attached to the slope of the fissure. The anchor rods 41 from the anchoring assembly 4 are then inserted into the side frame 2, extending deep into the crack slope. The gasket 43 is removed and placed at the hole. The screw 42 is passed through the gasket 43 and tightened to the end of the anchor rod 41 to complete the positioning. After positioning, the flexible rubber rod 44 is inserted into the crack slope, and secured with the anti-detachment block 45 on the outside of the flexible rubber rod 44. The wire coil 48 is then passed through the insertion hole 46 of the flexible rubber rod 44 and tightened. The deformation effect of the flexible rubber rod 44 helps prevent soil erosion on the liquefied fissure slope. The reinforcement plate 1 remains taut and positioned on the slope. In the event of ground subsidence, the second screw 52 on the square column 51 of the anti-settlement component 5 can be unscrewed. Using a tool, the third screw 53 can be rotated, pushing the bottom rotating column 54 and base 55 down to press firmly against the ground, thus preventing the risk of subsidence of the reinforcement plate 1. Pre-construction preparations include: cleaning loose soil and rock in the cracked area, marking the bonding position of the reinforcement plate 1 (perpendicular to the crack direction), preparing tools such as screw wrenches, Phillips screwdrivers, and wire, and checking the integrity of each component (vertical beam 31, anchor rod 41, flexible rubber rod 44, etc.). The vertical beam 31 (frustum-shaped) is then bonded to the preset position on the outside of the reinforcement plate 1 and fixed. The slots 32 on both sides of beam 31 engage with the buckles 33 of positioning seat 34, forming a longitudinal support frame between adjacent vertical beams 31. The slots 35 of positioning seat 34 need to be aligned to reserve installation space for the anti-detachment bracket 610 of pretensioning assembly 6. The pretensioning steel bar 69 (telescopic steel sleeve) is placed into the vertical slot of support rod 61, so that the support slider 65 slides along guide frame 66, and its top arc groove fits and supports the bottom of pretensioning steel bar 69. Then, the damping rod 64 is put into spring 67, and the support slider 65 is rotatably connected to the damping rod 64 to complete the initial assembly of pretensioning assembly 6. The anchor rod 41 is inserted into the four corner reserved holes of side frame 2, screw in screw 42 and put on washer 43, and tighten screw 42 with wrench so that washer 43 is tightened. 43. Tightly fit the side frame 2 to achieve initial rigid anchoring of the reinforced structure and the stratum. Insert the flexible rubber rod 44 (round end facing forward) into the middle hole of the side frame 2 and use the triangular anti-detachment block 45 to prevent the rubber rod from coming out. Pass the wire coil 48 through the adjacent insertion hole 46 on the surface of the rubber rod and tighten it to enhance the structural stability of the rubber rod. Finally, insert the hole-expanding rod 49 into the extrusion hole 47 to open the end of the rubber rod and make it fit tightly against the stratum hole wall to complete the flexible adaptation anchoring and adapt to the deformation characteristics of the liquefied stratum. Insert the square column 51 through the middle hole of the reinforcing plate 1 and fix it. Screw the second screw 52 into the square column 51. Then screw the third screw 53 into the square column 51 so that the top of the third screw 53 abuts against the second screw 52.Insert a Phillips screwdriver into the Phillips head slot at the top of screw 53, rotate screw 53 to rotate the bottom rotating column 54, causing the base 55 to gradually unfold and fit against the reinforcing plate 1. Observe the fit between the base 55 and the reinforcing plate 1, ensuring that the base 55 is fully unfolded to increase the contact area with the ground, distribute the upper load, and complete the arrangement of the anti-settlement structure. Place the pre-installed pre-tightening assembly 6 (support rod 61 + pre-tightening steel bar 69) between adjacent vertical beams 31, so that the anti-detachment brackets 610 at both ends of the pre-tightening steel bar 69 are inserted into the slots 35 of the positioning seat 34; fit the positioning plate 62 at the bottom of the support rod 61 against the ground surface, insert the positioning nail 63 into the end hole of the positioning plate 62, so that the limiting block 68 of the damping rod 64... (With the rounded corner facing forward) Insert the rod into the slot of the positioning nail 63 to complete the positioning. Press down on the support rod 61 to make the support slider 65 slide along the guide groove. The spring 67 is compressed and drives the damping rod 64 to deform, applying pre-tightening force to the pre-tightening steel bar 69. At the same time, check the fit of each component (vertical beam 31 and positioning seat 34, anchor rod 41 and side frame 2, etc.) to ensure that the reinforced structure forms a cooperative force-bearing system. After the reinforcement is completed, regularly check the expansion and contraction of the pre-tightening steel bar 69, the fit of the flexible rubber rod 44, and the settlement of the base 55. If ground vibration occurs, the support force of the base 55 can be finely adjusted by adjusting the screw 3 53, or the tightness of the wire coil 48 can be supplemented to ensure the long-term stability of the reinforced structure in a highly liquefied geological environment.
