Description

Technical Field

[0001] This utility model relates to the field of foundation reinforcement equipment technology, specifically a foundation reinforcement mechanism. Background Technology

[0002] Foundation reinforcement mechanisms are the core mechanical equipment or working devices used to perform specific reinforcement methods, such as the grouting system of high-pressure jet grouting piles, the mixing drill bit system of deep mixing piles, or the hydraulic pile driving system of static pressure piles. Their function is to drill holes, inject grout, mix soil layers, or apply pressure to form piles or structures that reinforce the foundation.

[0003] Currently, self-built houses or low-rise buildings in villages often experience foundation subsidence after residents have lived there for a considerable period, leading to house collapses and tilting due to geological reasons and construction errors. This poses a significant safety hazard to residents and threatens their lives. Therefore, there is an urgent need for inventors to develop a device that can provide secondary reinforcement for building structures. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a foundation reinforcement mechanism to solve the technical problem of inconvenience in secondary foundation reinforcement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foundation reinforcement mechanism, comprising a foundation structure body and a connecting device. The surface of the foundation structure body is provided with several fixing holes. A first connecting plate and a second connecting plate are provided on the upper side of the foundation structure body. One side of the first connecting plate is provided with two sets of grooves, and the surfaces of the two sets of grooves are provided with several through holes. One side of the second connecting plate is fixedly connected with two sets of protrusions, and the surfaces of the two sets of protrusions are provided with several connecting holes. The first connecting plate and the second connecting plate are inserted and fixed to the outside of the foundation structure body. The several connecting holes correspond to the several through holes and the several fixing holes and are connected by bolts. One end of the connecting device is movably connected to the first connecting plate and the second connecting plate, and the other end of the connecting device is embedded below the concrete.

[0006] By adopting the above-mentioned technical solution, a two-way force transmission system between above-ground and underground is constructed through the core load-bearing structure of the main foundation structure and the collaborative mechanism of multiple components. The fixing holes on the surface of the main body can be directly anchored to the prefabricated foundation components, which significantly improves the anti-settlement capacity.

[0007] Furthermore, the fixing holes are arranged in a circular, uniform, and equidistant pattern for further fixing of the main body of the foundation structure.

[0008] By adopting the above technical solution, the circular and equidistantly arranged holes on the surface of the main body of the foundation structure disperse the anchor bolt fastening force along the circumferential direction, avoiding structural cracking or deformation caused by local stress concentration.

[0009] Furthermore, the two sets of protrusions cooperate with the two sets of grooves, and through the connection with the bolts, the position of the main body of the foundation structure and the first connecting plate and the second connecting plate is defined.

[0010] By adopting the above technical solution, the geometric engagement of the protrusion and the groove forms the physical positioning core. During installation, the protrusion is embedded in the groove to form a pre-constraint, eliminating human alignment errors. After the bolt passes through, a double locking effect is generated.

[0011] Furthermore, the connecting device is provided in four sets, evenly distributed at the four corners of the first connecting plate and the second connecting plate.

[0012] By adopting the above technical solution, the four sets of connecting devices form a spatial tetrahedral anchoring system at the four corners of the connecting plate, realizing full-domain degree of freedom constraint, and the four anchoring points synchronously suppress the horizontal displacement and overturning moment of the structure.

[0013] Furthermore, the connecting device includes a first rotating rod, a connecting rod, and a second rotating rod; the connecting rod is coaxially connected to the first rotating rod and the second rotating rod, and the outer wall of the connecting rod is threadedly engaged with the inner walls of the first rotating rod and the second rotating rod. The overall length of the connecting device can be adjusted by rotating the connecting rod to adapt to the underground fixing requirements at different depths.

[0014] By adopting the above technical solution, when rotating the connecting rod, the external thread of the connecting rod and the internal threads of the first rotating rod and the second rotating rod can achieve stepless adjustment of the total length, and different anchoring depths can be matched without replacing the parts.

[0015] Furthermore, the connecting device includes a fixing plate, and the fixing plate is rotatably connected to a rotating plate via a rotating shaft.

[0016] By adopting the above technical solution, the hinge chain from the fixed plate to the rotating shaft and then to the rotating plate constitutes the underground displacement relief hub: when the frost-susceptible soil or quicksand layer undergoes horizontal creep, the rotating shaft allows the rotating plate to deflect adaptively, releasing the tearing stress of the soil displacement on the superstructure.

[0017] Furthermore, a first rotating rod is rotatably connected to the outer wall of the rotating plate, a connecting rod is threadedly connected to the outer wall of the first rotating rod, and a second rotating rod is threadedly connected to the end of the connecting rod.

[0018] By adopting the above technical solution, the linkage system from the rotating plate to the second rotating rod innovatively integrates multi-degree-of-freedom adjustment functions. The deflection of the rotating plate drives the first rotating rod to change the pitch angle, while the threaded connecting rod converts it into axial extension and retraction motion, so that the end second rotating rod can find the optimal anchoring posture in deep soil.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model establishes an anti-settlement foundation through the anchoring design of the main body of the foundation structure and the fixing hole. It uses the protrusion-groove interlocking structure of the first connecting plate and the second connecting plate to form a physical interlock. Then, the bolts pass through the connecting hole, through hole and fixing hole to achieve triple mechanical locking, which efficiently converts the external load into axial pressure and significantly suppresses the lateral displacement and shear deformation of the structure.

[0021] 2. This utility model constructs a spatial stability system through four sets of connecting devices distributed at the four corners of the connecting plate. The hinged design of its rotating shaft and rotating plate can release the creep stress of the soil. At the same time, the connecting rod drives the first rotating rod and the second rotating rod to adjust the anchoring depth through threaded extension and retraction. Finally, an adaptive force transmission chain is formed from hinged buffer to threaded self-locking and then to deep anchoring, ensuring the overall structural stability in complex geological conditions such as soft soil and frost heave.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In this embodiment:

[0029] A foundation reinforcement mechanism, such as Figure 1-4 As shown, the structure includes a foundation structure body 1 and a connecting device 10. The surface of the foundation structure body 1 has several fixing holes 2. A first connecting plate 3 and a second connecting plate 4 are provided on the upper side of the foundation structure body 1. Two sets of grooves 7 are provided on one side of the first connecting plate 3, and several through holes 8 are provided on the surface of the two sets of grooves 7. Two sets of protrusions 5 are fixedly connected to one side of the second connecting plate 4, and several connecting holes 6 are provided on the surface of the two sets of protrusions 5. The first connecting plate 3 and the second connecting plate 4 are inserted and fixed to the outside of the foundation structure body 1. The several connecting holes 6 correspond to the several through holes 8 and the several fixing holes 2 and are connected by bolts 9. Then, one end of the connecting device 10 is movably connected to the first connecting plate 3 and the second connecting plate 4, and the other end of the connecting device 10 is buried under the concrete. Through the core bearing structure of the foundation structure 1 and the multi-component collaborative mechanism, a two-way force transmission system between the ground and the underground is constructed. The fixing holes 2 on the surface of the main body can be directly anchored to the foundation prefabricated parts, which significantly improves the anti-settlement ability. The first connecting plate 3 and the second connecting plate 4 are interlocked by the protrusion 5 and the groove 7 to wrap the main body. Then, the bolts 9 pass through the connecting hole 6, the through hole 8 and the fixing hole 2 to form a triple mechanical lock, which efficiently converts the external load into axial pressure and avoids shear failure caused by lateral displacement.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The fixing holes 2 are arranged in a circular, uniform, and equidistant pattern to further fix the main body 1 of the foundation structure. The circular and equidistant arrangement of the fixing holes 2 on the surface of the main body 1 of the foundation structure disperses the anchor bolt tightening force along the circumference. The standardized hole spacing provides a precise positioning benchmark for construction, and multiple bolts can be locked synchronously quickly without on-site measurement, which significantly shortens the construction cycle. This design can also adapt to multi-directional foundation reaction forces. When the soil undergoes non-uniform compression, the annular hole group absorbs differential settlement through the coordinated deformation of each anchor point, ensuring that the structure always maintains horizontal stability in complex geological conditions such as soft soil and backfill soil.

[0031] See Figure 1 , Figure 4 Two sets of protrusions 5 and two sets of grooves 7 cooperate to define the position of the main body 1 of the foundation structure, the first connecting plate 3 and the second connecting plate 4 through the connection with bolts 9. The geometric engagement of protrusions 5 and grooves 7 constitutes the physical positioning core. During installation, the protrusions are embedded in the grooves to form a pre-constraint, eliminating manual alignment errors. After the bolts 9 pass through, a double locking effect is generated. First, it restricts the longitudinal tendency of the protrusions to come out in the grooves. Second, the bolt pre-tightening force squeezes the interlocking surface to generate static friction. Even if strong earthquakes or mechanical vibrations occur, the connecting plate and the main body still maintain a zero gap state.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The connecting device 10 is provided in four sets, evenly distributed at the four corners of the first connecting plate 3 and the second connecting plate 4. The four sets of connecting devices 10 form a spatial tetrahedral anchoring system at the four corners of the connecting plate, realizing full-domain degree of freedom constraint. The four anchoring points synchronously suppress the horizontal displacement and overturning moment of the structure. When the foundation softens in a certain area, the independent connecting device can dynamically adjust the expansion and contraction of each anchoring point and maintain the overall levelness through adaptive leveling. This distributed support solves the limitations of single-point anchoring and is particularly suitable for easily deformable scenarios such as river embankments and slope protection.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The connecting device 10 includes a first rotating rod 1004, a connecting rod 1005, and a second rotating rod 1006. The connecting rod 1005 is coaxially connected to the first rotating rod 1004 and the second rotating rod 1006, and the outer wall of the connecting rod 1005 is threadedly engaged with the inner walls of the first rotating rod 1004 and the second rotating rod 1006. The overall length of the connecting device 10 can be adjusted by rotating the connecting rod 1005 to adapt to the underground fixing requirements at different depths. When rotating the connecting rod 1005, the engagement of its external thread with the internal threads of the first rotating rod 1004 and the second rotating rod 1006 achieves stepless adjustment of the total length, matching different anchoring depths without replacing parts. The optimized thread helix angle design ensures that the rotational torque is efficiently converted into axial thrust, and the thread pair is self-locking and anti-loosening after the force is stopped, completely eliminating the device's shrinkage failure caused by vibration in seepage soil layers. This design frees construction from dependence on precast deep piles and significantly reduces geotechnical engineering costs.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The connecting device 10 includes a fixed plate 1001, which is rotatably connected to a rotating plate 1003 via a rotating shaft 1002. The hinge chain from the fixed plate 1001 to the rotating shaft 1002 and then to the rotating plate 1003 constitutes an underground displacement relief hub. When the frost-susceptible soil or quicksand layer undergoes horizontal creep, the rotating shaft allows the rotating plate 1003 to adaptively deflect, releasing the tearing stress of the soil displacement on the superstructure. This rotating mechanism serves as a load transition interface, smoothly transmitting the vertical pressure borne by the fixed plate 1001 to the telescopic rod system at the rear end of the rotating plate 1003, thus avoiding component fracture caused by stress mutation.

[0035] See Figure 1 , Figure 2 , Figure 3 , Figure 4The outer wall of the rotating plate 1003 is rotatably connected to the first rotating rod 1004, and the outer wall of the first rotating rod 1004 is threadedly connected to the connecting rod 1005. The end of the connecting rod 1005 is threadedly connected to the second rotating rod 1006. The linkage system from the rotating plate 1003 to the second rotating rod 1006 innovatively integrates multi-degree-of-freedom adjustment functions. The deflection of the rotating plate drives the first rotating rod to change the pitch angle, and the threaded connecting rod 1005 converts it into axial extension and contraction motion, so that the end second rotating rod 1006 can find the optimal anchoring posture in deep soil. The coaxial design ensures that the force transmission path is strictly distributed along the axis, eliminating the risk of bending. This compact structure can still be efficiently deployed in narrow spaces such as pipe corridors and tunnels. Complex working conditions can be adapted simply by rotating the connecting rod with a wrench.

[0036] The implementation principle of this embodiment is as follows: Using the main body 1 of the foundation structure as the core load-bearing structure, the evenly spaced fixing holes 2 on its surface can enhance the fixation to the ground using bolts or anchors. First, the first connecting plate 3 and the second connecting plate 4 are installed on the outside of the main body 1 of the foundation structure via a plug-in connection. Specifically, the protrusion 5 of the second connecting plate 4 is embedded into the groove 7 of the first connecting plate 3 for initial positioning. Then, bolts 9 are used to pass through the connecting hole 6 of the protrusion 5 and the through hole 8 of the groove 7 to complete the tight connection, thereby forming a surrounding fixation of the main body 1 of the foundation structure. Four sets... The connecting devices 10 are distributed at the four corners of the first connecting plate 3 and the second connecting plate 4 and extend into the ground. Each set of connecting devices 10 starts from the fixed plate 1001 and is hinged to the rotating plate 1003 through the rotating shaft 1002 to adapt to the displacement of the underground soil. The rotating plate 1003 drives the first rotating rod 1004 to rotate, which drives the connecting rod 1005 that is threaded with it to extend and retract. The second rotating rod 1006 at the end of the connecting rod 1005 is further screwed into the deep soil layer. The overall length of the device can be flexibly adjusted by rotating the connecting rod 1005 to meet the anchoring requirements of different depths.
