Description

Technical Field

[0001] The present invention relates to the technical field of ground collapse reinforcement, and more particularly, to a ground anti-collapse reinforcement device. Background Art

[0002] In actual use, some existing ground reinforcement devices have a large overall vibration amplitude when subjected to ground vibrations, which easily leads to problems such as loosening and deformation of the foundation soil, and even foundation settlement. When the device is subjected to lateral forces, its support structure shows obvious instability, and the support structure may not be able to effectively resist the influence of lateral forces, resulting in structural displacement. Such displacement not only affects the normal operation of the device and makes it unable to accurately play the reinforcement role, but also may pose a serious threat to the ground stability. Infrastructure such as buildings and roads on the ground may tilt or collapse due to ground displacement, bringing huge hidden dangers to people's lives and property safety.

[0003] How to invent a ground anti-collapse reinforcement device to solve these problems has become an urgent problem for those skilled in the art. Summary of the Invention

[0011] Preferably, the support and shock absorption assembly includes a support, a positioning frame, a buffer block, a shock absorber, a rubber isolation pad, a limit anchor rod, and two partition plates fixedly connected to the installation base. The two partition plates are symmetrically arranged. The surface layer, the buffer block, the rubber isolation pad, the support, and the limit anchor rod are distributed from top to bottom in sequence. The top of the buffer block fits against the bottom of the surface layer. A grouting area is provided at the bottom of the support. A through hole matching the limit anchor rod is provided in the support. The lower end of the limit anchor rod passes through the through hole and then penetrates the bottom of the installation base, and extends downward into the soil layer of the lower layer of the foundation pit. The top of the limit anchor rod abuts against the bottom wall of the grouting area.

[0012] Preferably, a blocking layer is fixedly provided at the top of the support. Installation sleeves are respectively installed on the upper and lower parts of the rubber isolation pad. Installation bolts are provided in the installation sleeves. The end of the installation bolt located in the upper part of the rubber isolation pad penetrates the bottom wall of the buffer block and extends into the buffer block. The end of the installation bolt located in the lower part of the rubber isolation pad penetrates the blocking layer and the top wall of the support, and extends into the support. A steel bar frame layer is provided between the two partition plates above the blocking layer. The steel bar frame layer is arranged around the rubber isolation pad in a cross manner.

[0013] Preferably, there is a gap between the top of the partition plate and the top of the installation base. Multiple shock absorbers for buffering both sides of the buffer block are installed on the top of the installation base. The side wall of the buffer block abuts against the output end of the shock absorber. The space enclosed by the bottom of the blocking layer and the two partition plates is a filling area. Filling materials are laid in the filling area. A positioning frame is provided on the installation base. The positioning frame is fixedly connected to the installation base through positioning bolts. A sound-absorbing layer is filled between the positioning frame and the partition plate.

[0014] Preferably, the reinforcement assembly includes an injection channel provided in the limit anchor rod and a slurry outlet communicated with the bottom of the injection channel. The end of the slurry outlet penetrates the side wall of the limit anchor rod. A first limit cavity and multiple second limit cavities are also provided in the limit anchor rod below the injection channel. The multiple second limit cavities are annularly and equidistantly distributed around the first limit cavity. The first limit cavity is communicated with the second limit cavities. A bent blocking plate for blocking the slurry outlet is fixedly installed on the top wall of the slurry outlet. A frustum-shaped column is slidably connected in the first limit cavity. The upper end of the frustum-shaped column is fixedly connected to a sliding rod. The end of the sliding rod penetrates the bottom of the injection channel and extends into the injection channel. The end of the sliding rod located in the injection channel is fixedly connected to a pressing plate.

[0015] Preferably, the top of the frustum column is elastically connected to the top of the first limiting cavity through a first spring. The pressing plate is arranged to match the injection channel and the slurry outlet. The end of the pressing plate abuts against the side wall of the bent baffle.

[0016] Preferably, a through hole matching the top of the electric push rod is provided through the side wall of the limiting anchor rod. The cross section of the electric push rod is arranged in a T shape. In the initial state, the ball is located inside the first limiting cavity. When the bottom wall of the pressing plate is attached to the bottom wall of the injection channel, the column surface of the frustum column abuts against the spherical surface of the ball, and the top of the electric push rod extends to the outside of the limiting anchor rod.

[0017] Preferably, the injection channel is a channel for injecting reinforcing materials. The reinforcing materials are injected into the injection channel through an external high-pressure pump, and the reinforcing materials will be sprayed into the soil layer at the bottom of the foundation pit through the slurry outlet.

[0018] Preferably, the induction ejection assembly includes an induction sensor arranged inside a rubber isolation pad. The induction sensor is used to sense the fluctuation range of the rubber isolation pad. The induction sensor is electrically connected to the corresponding electric push rod. When the induction sensor senses that the fluctuation range of the rubber isolation pad exceeds the threshold, it will send a signal to control the electric push rod to extend the piston push rod. At this time, the piston push rod will deeply penetrate into the soil layer through the pointed cone part.

[0019] The beneficial effects of the present invention are as follows:

[0020] Through the hierarchical setting and coordinated operation of the support shock absorption assembly, the reinforcement assembly and the induction ejection assembly, the effective transmission and dispersion of force are realized. The loads on the surface layer are sequentially transmitted to the soil layer through the buffer block, the rubber isolation pad, the support and the limiting anchor rod, ensuring the stable transmission of force and improving the overall stability of the device; the rubber isolation pad, the shock absorber and the buffer block cooperate with each other to form a multiple shock absorption system, reducing the influence of ground vibration on the device and the foundation. At the same time, components such as the limiting anchor rod, the support and the filling material work together to enhance the bearing capacity and anti-deformation ability of the foundation, providing a solid foundation for ground anti-collapse.

[0021] Through the synergistic effect of the reinforcement material and the electric push rod, not only can the reinforcement material fully fill the soil layer pores, but also the electric push rod destroys the soil layer structure, increasing the bonding force between the reinforcement material and the soil layer, and improving the integrity and reliability of the reinforcement effect; the cooperation of the reinforcement component and the induction ejection component enables the reinforcement process to be automatically adjusted according to the actual situation of the foundation. When the sensed vibration exceeds the threshold, the induction ejection component promptly extends the electric push rod to further enhance the reinforcement effect, realizing real-time monitoring and dynamic reinforcement of the foundation, and improving the reliability of the device.

Specific implementation manner

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Example 1, referring to Figures 1-6 , a ground anti-collapse reinforcement device, including a surface layer 10 and a foundation pit 2 opened below the surface layer 10. An installation base 1 is arranged in the foundation pit 2, and further includes:

[0035] Support and shock absorption assembly: The support and shock absorption assembly is arranged in the installation base 1. While supporting the surface layer 10, the support and shock absorption assembly can also perform shock absorption and buffering treatment to reduce the impact of ground vibration on the device and the foundation.

[0036] Reinforcement assembly: The reinforcement assembly is arranged at the bottom of the support and shock absorption assembly, and the reinforcement assembly is used to further fix the installation base 1.

[0037] Inductive ejection assembly: The inductive ejection assembly is arranged inside the reinforcement assembly. When sensing the vibration energy, the inductive ejection assembly can further strengthen the grasping force between the reinforcement assembly and the soil layer.

[0038] Furthermore, the support and shock-absorbing assembly includes a support 3, a positioning frame 4, a buffer block 5, a shock absorber 51, a rubber isolation pad 6, a limit anchor rod 7, and two partition plates 11 fixedly connected to the installation base 1. The two partition plates 11 are symmetrically arranged. The surface layer 10, the buffer block 5, the rubber isolation pad 6, the support 3, and the limit anchor rod 7 are distributed from top to bottom. Through the hierarchical arrangement of different components, the transmission and dispersion of force are realized, improving the stability and reliability of the device. The top of the buffer block 5 is in contact with the bottom of the surface layer 10. The buffer block 5 provides preliminary buffering, and the rubber isolation pad 6 further reduces vibration and decreases vibration transmission. A grouting area 31 is provided at the bottom of the support 3 to facilitate the injection of reinforcement materials. A through hole matching the limit anchor rod 7 is provided inside the support 3. The lower end of the limit anchor rod 7 passes through this through hole and then penetrates the bottom of the installation base 1 and extends downward into the soil layer of the lower layer of the foundation pit 2. The top of the limit anchor rod 7 abuts against the bottom wall of the grouting area 31.

[0039] A blocking layer 32 is fixedly provided at the top of the support 3. Installation sleeves 61 are respectively installed on the upper and lower parts of the rubber isolation pad 6. Installation bolts are provided inside the installation sleeves 61. The end of the installation bolt located in the upper part of the rubber isolation pad 6 penetrates the bottom wall of the buffer block 5 and extends into the buffer block 5. The end of the installation bolt located in the lower part of the rubber isolation pad 6 penetrates the blocking layer 32 and the top wall of the support 3 and extends into the support 3. A steel bar frame layer 62 is provided between the two partition plates 11 above the blocking layer 32. The steel bar frame layer 62 is arranged around the rubber isolation pad 6 in a cross manner to further enhance the support effect on the surface layer 10.

[0040] It should be noted that there is a gap between the top of the partition plate 11 and the top of the installation base 1. This gap ensures that the buffer block 5 can slide within a certain area, and this sliding does not affect the support effect on the surface layer 10. Multiple groups of shock absorbers 51 for buffering both sides of the buffer block 5 are installed on the top of the installation base 1. The side wall of the buffer block 5 abuts against the output end of the shock absorber 51. Through the setting of the shock absorber 51, another layer of limit can be applied to the buffer block 5. The space enclosed by the bottom of the blocking layer 32 and the two partition plates 11 is a filling area 12. Filling materials are laid in the filling area 12. Cement, coal gangue, slag and other mixed materials are selected as the filling materials. These materials have good fluidity and filling properties and can effectively fill the voids in the subsided area, enhancing the bearing capacity of the foundation. At the same time, appropriate additives, such as early strength agents and water reducers, can be added according to the specific situation of the subsided area to improve the performance of the filling materials. A positioning frame 4 is provided on the installation base 1. The positioning frame 4 is fixedly connected to the installation base 1 through positioning bolts 41. A sound-absorbing layer 42 is filled between the positioning frame 4 and the partition plate 11. The sound-absorbing layer 42 can be made of porous rock wool, which plays a role in sound absorption and reducing vibration transmission. The side wall of the foundation pit 2 is coated with a waterproof layer 21, reducing the erosion of water vapor on the devices inside the installation base 1.

[0041] In this embodiment, first, place the sound-absorbing layer 42 in a suitable position, and then fix the positioning frame 4 through the positioning bolts 41 to achieve the positioning of the sound-absorbing layer 42. Coat the waterproof layer 21 on the side wall of the foundation pit 2, then place the installation base 1 into the foundation pit 2, place the support 3, pass the limit anchor rod 7 through the through hole of the support 3, and ensure that its top abuts against the bottom wall of the grouting area 31. Then install the support 3 on the installation base 1. At this time, the installation base 1 can be fixed by the limit anchor rod 7. Then, lay the filling material in the filling area 12. The laying of the filling material can fill the voids in the foundation and improve the stability of the foundation. After laying, install the blocking layer 32 and the rubber isolation pad 6. The rubber isolation pad 6 can reduce the vibration transmission, protect the upper structure, and at the same time transmit the vibration force to the buffer block 5 to achieve force unloading and avoid the transmission of this part of the vibration force to the surface layer 10. Then weld the steel bar frame layer 62 around the rubber isolation pad 6. The steel bar frame layer 62 further enhances the stability of the rubber isolation pad 6 and ensures its reliability during operation. Then install the buffer block 5 and the shock absorber 51. The buffer block 5 provides preliminary buffering for the surface layer 10, and the shock absorber 51 further dampens the buffer block 5, jointly reducing the impact of ground vibration on the device. Finally, cover the surface layer 10 on the installation base 1.

[0042] The upper and lower parts of the rubber isolation pad 6 are respectively connected to the upper buffer block 5 and the lower blocking layer 32 through the installation sleeve 61 and the installation bolt to ensure its installation stability. At the same time, the steel bar frame layer 62 arranged between the two partition plates 11 above the blocking layer 32 is cross-arranged around the rubber isolation pad 6, further enhancing the stability of the rubber isolation pad 6 and the supporting effect on the surface layer 10; there is a gap between the top of the partition plate 11 and the top of the installation base 1, which enables the buffer block 5 to slide within a certain area without affecting the support for the surface layer 10. Multiple groups of shock absorbers 51 on the top of the installation base 1 buffer both sides of the buffer block 5, restricting the excessive sway of the buffer block 5.

[0043] Through the synergistic effect of the rubber isolation pad 6, the shock absorber 51 and the buffer block 5, multiple dampings of ground vibration are achieved. The rubber isolation pad 6 reduces the vibration transmission, the shock absorber 51 further dampens the buffer block 5, and the buffer block 5 provides preliminary buffering for the surface layer 10, jointly reducing the impact of ground vibration on the device and protecting the safety of the upper structure; the rubber isolation pad 6 transmits the vibration force to the buffer block 5 to achieve effective force unloading of the vibration force, avoiding the direct transmission of the vibration force to the surface layer 10, reducing the vibration amplitude of the surface layer 10, and reducing the risk of ground collapse; laying the filling material in the filling area 12 fills the voids in the foundation, improves the density and stability of the foundation, enhances the bearing capacity of the foundation, and provides a solid foundation for ground anti-collapse.

[0044] Embodiment 2, refer toFigures 6-8 The reinforcement component includes an injection channel 71 provided in the limit anchor rod 7 and a slurry outlet 72 connected to the bottom of the injection channel 71. The end of the slurry outlet 72 penetrates through the side wall of the limit anchor rod 7. A first limit cavity 73 and a plurality of second limit cavities 74 are also provided in the limit anchor rod 7 below the injection channel 71. The plurality of second limit cavities 74 are annularly and equidistantly distributed around the first limit cavity 73. The first limit cavity 73 is connected to the second limit cavities 74. A bent blocking plate 721 for blocking the slurry outlet 72 is fixedly installed on the top wall of the slurry outlet 72. The setting of the bent blocking plate 721 prevents the outside soil layer from entering the injection channel 71. A frustum column 82 is slidably connected in the first limit cavity 73. The upper end of the frustum column 82 is fixedly connected to a sliding rod 8. The end of the sliding rod 8 penetrates through the bottom of the injection channel 71 and extends into the injection channel 71. A pressing plate 81 is fixedly connected to the end of the sliding rod 8 inside the injection channel 71. When the reinforcement material is injected, the pressure causes the pressing plate 81 to move downward, driving the sliding rod 8 and the frustum column 82 to descend.

[0045] The injection channel 71 is a channel for injecting the reinforcement material. The reinforcement material is injected into the injection channel 71 through an external high-pressure pump. At this time, under the extrusion of the reinforcement material, the bent blocking plate 721 will turn outwards to open the slurry outlet 72, and the reinforcement material will be sprayed into the soil layer at the bottom of the foundation pit 2 through the slurry outlet 72, thereby realizing the reinforcement of the soil layer.

[0046] Further, the top of the frustum column 82 and the top of the first limit cavity 73 are elastically connected by a first spring 83. When the frustum column 82 descends, the first spring 83 will be stretched. The pressing plate 81 is matched with the injection channel 71 and the slurry outlet 72 to ensure that the reinforcement material can directly act on the pressing plate 81. The end of the pressing plate 81 abuts against the side wall of the bent blocking plate 721, which can effectively support the bent blocking plate 721 and prevent the bent blocking plate 721 from turning inwards under the pressure of the outside soil layer. An electric push rod 9 is slidably arranged inside the second limit cavity 74. A piston push rod 91 is arranged inside the electric push rod 9. A pointed cone part 911 is provided at the end of the piston push rod 91. The electric push rod 9 and the second limit cavity 74 are elastically connected by a second spring 93. A ball 92 is rotatably clamped at the end of the electric push rod 9 close to the first limit cavity 73. When the frustum column 82 descends, its inclined surface will act on the electric push rod 9 through the ball 92.

[0047] It should be noted that a through hole matching the top of the electric push rod 9 is provided through the side wall of the limit anchor rod 7 to ensure that the electric push rod 9 can normally extend under the pressure of the frustum column 82. The cross section of the electric push rod 9 is T-shaped. In the initial state, the ball 92 is located inside the first limit cavity 73. When the bottom wall of the pressing plate 81 is attached to the bottom wall of the injection channel 71, the column surface of the frustum column 82 abuts against the spherical surface of the ball 92, and the top of the electric push rod 9 extends to the outside of the limit anchor rod 7. The extension of the electric push rod 9 can enhance the grip of the limit anchor rod 7.

[0048] In this embodiment, an external high-pressure pump injects a reinforcing material into the injection channel 71 of the limit anchor rod 7 (this step is carried out before laying the filling material in the first embodiment). The reinforcing material can be selected as epoxy resin, which has the advantages of high strength, strong bonding force, good chemical stability, etc. It can be used to reinforce geological materials such as soil and rock, improving their bearing capacity and anti-deformation ability. For example, when dealing with a karst collapse area, epoxy resin can be used to grout and reinforce the collapse area, fill the karst caves, and improve the stability of the foundation.

[0049] When the reinforcing material reaches near the slurry outlet 72, due to the pressure, the bending baffle 721 turns outwards, opening the slurry outlet 72, enabling the reinforcing material to be sprayed into the soil layer at the bottom of the foundation pit 2. This process can ensure that the reinforcing material fully fills the pores and defects in the soil layer, reducing the porosity of the soil layer and increasing the density of the soil layer, thereby improving the strength and stability of the soil layer. At the same time, the injected reinforcing material will press down on the pressing plate 81, and the pressure causes the pressing plate 81 to move downwards, driving the sliding rod 8 and the frustum column 82 to descend. When the frustum column 82 descends, its inclined surface contacts the ball 92, and the force is transmitted to the electric push rod 9 through the ball 92, causing the electric push rod 9 to slide in the second limiting cavity 74. A piston push rod 91 is arranged in the electric push rod 9, and a pointed cone portion 911 is provided at the end of the piston push rod 91. After the electric push rod 9 penetrates into the soil layer, the pointed cone portion 911 can further damage the soil layer structure, enabling the reinforcing material to better combine with the soil layer, thereby enhancing the reinforcement effect.

[0050] Under the dual actions of the extrusion and ejection of the reinforcing material and the electric push rod 9 by the frustum column 82, the pressure can be more evenly transmitted in the soil layer, avoiding the situation of excessive or too small local pressure. This helps to reduce the uneven deformation and damage of the soil layer during the reinforcement process, and improves the integrity and reliability of the reinforcement effect. In addition, after the electric push rod 9 is extruded and ejected by the frustum column 82, it can extend into the soil layer. On the one hand, it destroys the original pore structure and the arrangement of soil particles in the soil layer, which provides more favorable conditions for the entry and filling of the reinforcing material, enabling the reinforcing material to better combine with the soil layer and improving the reinforcement effect. On the other hand, due to the increased contact area with the soil layer, its frictional force and bonding force will also increase, thereby enhancing the grasping force of the limit anchor rod 7 and preventing the foundation from shifting and settling when subjected to external forces. The synergistic effect of the two makes the reinforced foundation more firm and reliable.

[0051] Embodiment Three, refer to Figures 6-9, the induction ejection assembly includes an induction sensor disposed inside the rubber isolation pad 6. The induction sensor is used to sense the fluctuation range of the rubber isolation pad 6. The induction sensor is electrically connected to the corresponding electric push rod 9. When the induction sensor senses that the fluctuation range of the rubber isolation pad 6 exceeds the threshold, it will send a signal to control the electric push rod 9 to extend the piston push rod 91. At this time, the piston push rod 91 will deeply penetrate into the soil layer through the tapered portion 911.

[0052] In this embodiment, the induction sensor disposed inside the rubber isolation pad 6 can sense the fluctuation range of the rubber isolation pad 6 in real time. These fluctuations may be caused by factors such as ground vibration and foundation settlement. When the induction sensor senses that the fluctuation range of the rubber isolation pad 6 exceeds the threshold, it will quickly send a signal. After receiving the signal, the electric push rod 9 will extend the piston push rod 91. The tapered portion 911 at the end of the piston push rod 91 can penetrate into the soil layer, increasing the contact area and friction between the electric push rod 9 and the soil layer, so as to better play the reinforcement role.

[0053] The induction ejection assembly can monitor the fluctuation of the rubber isolation pad 6 in real time. When the fluctuation exceeds the threshold, it can quickly respond and extend the electric push rod 9 in time to reinforce the foundation. This rapid response mechanism can effectively reduce the impact of ground vibration on the foundation and prevent further settlement or deformation of the foundation. The electric push rod 9 deeply penetrates into the soil layer through the tapered portion 911, which can increase the bearing capacity and anti-deformation ability of the foundation. In the case of vibration, the foundation can better bear the load of the upper structure, reducing the risk of structural damage and settlement; at the same time, it can cooperate with other reinforcement components (such as injection of reinforcement materials, fixing of limit anchor bolts 7, etc.) to achieve all-round reinforcement of the foundation. Through timely reinforcement measures, the deterioration of foundation problems can be avoided, and the cost of later maintenance and reinforcement can be reduced.

[0054] It should be noted that the specific model specifications of the induction sensor and the electric push rod 9 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0055] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
