[0001] The present invention relates to the technical field of ground collapse reinforcement, and in particular to a ground collapse prevention reinforcement device. Background Art

[0002] In actual use, when some existing ground reinforcement devices are subjected to ground vibration, the overall vibration amplitude of the device is large, which can easily lead to loosening and deformation of the foundation soil, and even foundation settlement. When the device is subjected to lateral force, its supporting structure shows obvious instability, and the supporting structure may not be able to effectively resist the influence of lateral force, thereby causing the structure to shift. This displacement will not only affect the normal operation of the device and make it unable to accurately play a reinforcement role, but may also pose a serious threat to the stability of the ground. Buildings, roads and other infrastructure on the ground may appear tilted, collapsed and other dangerous situations due to the displacement of the ground, posing huge hidden dangers to people's lives and property safety.

DETAILED DESCRIPTION

[0020] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0021] Embodiment 1, refer to Figure 1-Figure 6 A ground anti-collapse reinforcement device comprises a surface layer 10, a foundation pit 2 opened below the surface layer 10, a mounting base 1 is arranged in the foundation pit 2, and further comprises: Support shock absorbing assembly: The support shock absorbing assembly is arranged in the mounting base 1. The support shock absorbing assembly can support the surface layer 10 and perform shock absorbing and buffering treatment at the same time, thereby reducing the influence of ground vibration on the device and the foundation; Reinforcement component: The reinforcement component is arranged at the bottom of the supporting shock absorbing component, and the reinforcement component is used to further fix the mounting base 1; Inductive ejection assembly: The inductive ejection assembly is arranged inside the reinforcement assembly. When the vibration energy is sensed, the inductive ejection assembly can further strengthen the grip between the reinforcement assembly and the soil layer.

[0022] Furthermore, the support shock absorption assembly includes a support 3, a positioning frame 4, a buffer block 5, a shock absorber 51, a rubber seismic isolation pad 6, a limiting anchor rod 7, and two partition plates 11 fixedly connected to the mounting base 1. The two partition plates 11 are symmetrically arranged, and the surface layer 10, the buffer block 5, the rubber seismic isolation pad 6, the support 3, and the limiting anchor rod 7 are distributed in sequence from top to bottom. Through the layered arrangement of different components, force transmission and dispersion are achieved, and the stability and reliability of the device are improved. The top of the buffer block 5 is in contact with the bottom of the surface layer 10, and the buffer block 5 provides preliminary buffering. The rubber seismic isolation pad 6 further reduces shock and reduces 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 limiting anchor rod 7 is provided in the support 3. The lower end of the limiting anchor rod 7 passes through the through hole and then passes through the bottom of the mounting base 1, and extends downward to the soil layer of the lower layer of the foundation pit 2. The top of the limiting anchor rod 7 is against the bottom wall of the grouting area 31.

[0023] A barrier layer 32 is fixedly provided on the top of the support 3, and mounting sleeves 61 are respectively installed on the upper and lower parts of the rubber seismic isolation pad 6. A mounting bolt is arranged in the mounting sleeve 61. The end of the mounting bolt located at the upper part of the rubber seismic isolation pad 6 passes through the bottom wall of the buffer block 5 and extends to the inside of the buffer block 5. The end of the mounting bolt located at the lower part of the rubber seismic isolation pad 6 passes through the barrier layer 32 and the top wall of the support 3 and extends to the inside of the support 3. A steel frame layer 62 is arranged between the two partition plates 11 above the barrier layer 32. The steel frame layer 62 is cross-arranged around the rubber seismic isolation pad 6 to further enhance the supporting effect on the surface layer 10.

[0024] It should be noted that there is a gap between the top of the partition plate 11 and the top of the mounting base 1. This gap ensures that the buffer block 5 can slide in a certain area, and this sliding does not affect the supporting effect on the surface layer 10. A plurality of groups of shock absorbers 51 for buffering both sides of the buffer block 5 are installed on the top of the mounting base 1. The side wall of the buffer block 5 is against the output end of the shock absorber 51. Through the setting of the shock absorber 51, another layer of position limiting can be performed on the buffer block 5. The space enclosed by the bottom of the barrier layer 32 and the two partition plates 11 is the filling area 12. The filling area 12 is paved with filling materials, and a mixed material such as cement, coal gangue, slag, etc. is selected as the filling material. As fillers, these materials have good fluidity and filling properties, can effectively fill the gaps in the collapsed area, and enhance the bearing capacity of the foundation. At the same time, according to the specific conditions of the collapsed area, appropriate additives such as early strength agent, water reducer, etc. can be added to improve the performance of the filling material. A positioning frame 4 is arranged on the mounting base 1, and the positioning frame 4 is fixedly connected to the mounting base 1 through a positioning bolt 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 to absorb sound and reduce vibration transmission. The side walls of the foundation pit 2 are coated with a waterproof layer 21 to reduce the erosion of water vapor on the internal devices of the mounting base 1.

[0025] In this embodiment, first, the sound absorbing layer 42 is placed in a suitable position, and then the positioning frame 4 is fixed by the positioning bolt 41 to realize the positioning of the sound absorbing layer 42, and the waterproof layer 21 is coated on the side wall of the foundation pit 2, and then the mounting base 1 is placed in the foundation pit 2, and the support 3 is placed, and the limiting anchor rod 7 is passed through the through hole of the support 3, and it is ensured that its top is against the bottom wall of the grouting area 31, and then the support 3 is installed on the mounting base 1. At this time, the mounting base 1 can be fixed by the limiting anchor rod 7, and then the filling material is laid in the filling area 12. The laying of the filling material can fill the gaps in the foundation and improve the stability of the foundation. After laying, the installation base 1 is installed. The retaining layer 32 and the rubber isolation pad 6 can reduce the transmission of vibration and protect the upper structure. At the same time, it can transmit the vibration force to the buffer block 5 to achieve force unloading and prevent this part of the vibration force from being transmitted to the surface layer 10. Then, a steel frame layer 62 is welded around the rubber isolation pad 6. The steel frame layer 62 further enhances the stability of the rubber isolation pad 6 to ensure its reliability during operation. Then, the buffer block 5 and the shock absorber 51 are installed. The buffer block 5 provides preliminary buffering for the surface layer 10, and the shock absorber 51 further absorbs the shock of the buffer block 5, thereby jointly reducing the impact of ground vibration on the device. Finally, the surface layer 10 is covered on the mounting base 1.

[0026] The upper and lower parts of the rubber seismic isolation pad 6 are respectively connected to the upper buffer block 5 and the lower barrier layer 32 through the mounting sleeve 61 and the mounting bolt to ensure the stability of its installation. At the same time, the steel frame layer 62 arranged between the two partition plates 11 above the barrier layer 32 is cross-arranged around the rubber seismic isolation pad 6, further enhancing the stability of the rubber seismic 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 mounting base 1, which allows the buffer block 5 to slide in a certain area without affecting the support for the surface layer 10. The multiple groups of shock absorbers 51 on the top of the mounting base 1 buffer the two sides of the buffer block 5, thereby limiting the excessive shaking of the buffer block 5.

[0027] Through the synergistic effect of the rubber seismic isolation pad 6, the shock absorber 51 and the buffer block 5, multiple shock absorption of ground vibration is achieved. The rubber seismic isolation pad 6 reduces the transmission of vibration, the shock absorber 51 further absorbs the shock of the buffer block 5, and the buffer block 5 provides preliminary buffering for the surface layer 10, which together reduce the impact of ground vibration on the device and protect the safety of the upper structure; the rubber seismic isolation pad 6 transmits the vibration force to the buffer block 5, thereby achieving effective force unloading of the vibration force, avoiding 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; filling material is laid in the filling area 12 to fill the gaps in the foundation, thereby improving the density and stability of the foundation, enhancing the bearing capacity of the foundation, and providing a solid foundation for preventing ground collapse.

[0028] Example 2, refer to Figure 6-Figure 8 The reinforcement component includes an injection channel 71 provided in the limiting anchor rod 7 and a slurry outlet 72 connected to the bottom of the injection channel 71. The end of the slurry outlet 72 passes through the side wall of the limiting anchor rod 7. A limiting cavity 1 73 and a plurality of limiting cavities 2 74 are also provided in the limiting anchor rod 7 located at the lower side of the injection channel 71. The plurality of limiting cavities 2 74 are equidistantly distributed in an annular manner around the limiting cavity 1 73. The limiting cavity 1 73 is connected to the limiting cavity 2 74. A folding device for blocking the slurry outlet 72 is fixedly installed on the top wall of the slurry outlet 72. The setting of the bent plugging plate 721 and the folded plugging plate 721 prevents the external soil layer from entering the injection channel 71. A conical column 82 is slidably connected in the limiting cavity 73. The upper end of the conical column 82 is fixedly connected to a slide rod 8. The end of the slide rod 8 passes through the bottom of the injection channel 71 and extends to the inside of the injection channel 71. The end of the slide rod 8 located inside the injection channel 71 is fixedly connected to a pressure plate 81. When the reinforcement material is injected, the pressure causes the pressure plate 81 to move downward, driving the slide rod 8 and the conical column 82 to descend.

[0029] The injection channel 71 is a channel for injecting reinforcement materials. The reinforcement materials are injected into the injection channel 71 through an external high-pressure pump. At this time, under the extrusion of the reinforcement materials, the bending plugging plate 721 will be folded outward to open the slurry outlet 72, and the reinforcement materials will be sprayed into the soil layer at the bottom of the foundation pit 2 through the slurry outlet 72, thereby achieving reinforcement of the soil layer.

[0030] Furthermore, the top of the truncated cone 82 is elastically connected to the top of the limiting cavity 1 73 by a first spring 83. When the truncated cone 82 descends, the first spring 83 will be stretched. The pressure 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 pressure plate 81. The end of the pressure plate 81 is against the side wall of the bending plugging plate 721, which can effectively support the bending plugging plate 721 to prevent the bending plugging plate 721 from folding inward under the pressure of the external soil layer. An electric push rod 9 is slidingly arranged inside the limiting cavity 2 74, and a piston push rod 91 is arranged in the electric push rod 9. The end of the piston push rod 91 is provided with a pointed cone portion 911. The electric push rod 9 and the limiting cavity 2 74 are elastically connected by a second spring 93. The end of the electric push rod 9 close to the limiting cavity 1 73 is rotatably clamped with a ball 92. When the truncated cone 82 descends, its inclined surface will act on the electric push rod 9 through the ball 92.

[0031] It should be noted that the side wall of the limiting anchor rod 7 is penetrated by a through hole matching the top of the electric push rod 9 to ensure that the electric push rod 9 can be normally extended under the pressure of the truncated cone 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 limiting cavity 73. When the bottom wall of the pressure plate 81 is in contact with the bottom wall of the injection channel 71, the cylindrical surface of the truncated cone column 82 is against the spherical surface of the ball 92, and the top of the electric push rod 9 extends to the outside of the limiting anchor rod 7. The extension of the electric push rod 9 can enhance the grip of the limiting anchor rod 7.

[0032] In this embodiment, an external high-pressure pump injects the reinforcement material into the injection channel 71 of the limiting anchor rod 7 (this step is performed before laying the filling material in Example 1). The reinforcement material can be selected from epoxy resin, which has the advantages of high strength, strong adhesion, and good chemical stability. It can be used to reinforce geological materials such as soil and rock to improve their bearing capacity and deformation resistance. For example, when dealing with karst collapse areas, epoxy resin can be used to grout the collapse area to fill karst caves and improve the stability of the foundation.

[0033] When the reinforcing material reaches the vicinity of the slurry outlet 72, due to the pressure, the bending plugging plate 721 is folded outward, opening the slurry outlet 72, so that the reinforcing material can be sprayed into the soil layer at the bottom of the foundation pit 2. This process can ensure that the reinforcing material is fully filled into the pores and defects of the soil layer, reduce the porosity of the soil layer, and increase 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 the pressing plate 81 downward, and the pressure will cause the pressing plate 81 to move downward, and drive 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, so that the electric push rod 9 slides in the limit cavity 74. A piston push rod 91 is arranged in the electric push rod 9, and a pointed cone portion 911 is arranged 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 destroy the soil layer structure, so that the reinforcing material can be better combined with the soil layer, thereby enhancing the reinforcement effect.

[0034] Under the double-layer action of the reinforcement material and the electric push rod 9 squeezed out by the truncated cone column 82, the pressure can be transmitted more evenly in the soil layer, avoiding the situation where the local pressure is too large or too small, which helps to reduce the uneven deformation and damage of the soil layer during the reinforcement process and improve the integrity and reliability of the reinforcement effect; in addition, after the electric push rod 9 is squeezed out by the truncated cone 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 reinforcement material, so that the reinforcement material can better combine with the soil layer and improve the reinforcement effect. On the other hand, due to the increase in the contact area with the soil layer, its friction and adhesion will also increase, thereby enhancing the grip of the limit anchor 7 and preventing the foundation from displacement and settlement when subjected to external force. The synergistic effect of the two makes the reinforced foundation more solid and reliable.

[0035] Example 3, refer to Figure 6-Figure 9The inductive ejection assembly includes an inductive sensor arranged inside the rubber isolation pad 6. The inductive sensor is used to sense the fluctuation range of the rubber isolation pad 6. The inductive sensor is electrically connected to the corresponding electric push rod 9. When the inductive 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 penetrate deeply into the soil layer through the pointed cone portion 911.

[0036] In this embodiment, the inductive sensor arranged inside the rubber seismic isolation pad 6 can sense the fluctuation range of the rubber seismic isolation pad 6 in real time. These fluctuations may be caused by factors such as ground vibration and foundation settlement. When the inductive sensor senses that the fluctuation range of the rubber seismic 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 pointed cone 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, thereby better playing a reinforcing role.

[0037] The inductive ejection component can monitor the fluctuation of the rubber seismic isolation pad 6 in real time. When the fluctuation exceeds the threshold, it can respond quickly 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 the foundation from further settling or deformation. The electric push rod 9 is deeply embedded in the soil layer through the pointed cone portion 911, which can increase the bearing capacity and anti-deformation ability of the foundation. Under vibration conditions, the foundation can better withstand the load of the superstructure and reduce the risk of structural damage and settlement. At the same time, it can cooperate with other reinforcement components (such as injection of reinforcement materials, fixation of limit anchor rods 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 subsequent maintenance and reinforcement can be reduced.

[0038] It should be noted that the specific model specifications of the inductive sensor and the electric push rod 9 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

For those skilled in the art, the present invention may have various modifications and variations. 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.
