Technical Field

[0001] This invention relates to the field of vibration isolation technology, specifically to a foam-filled vibration isolation trench. Background Technology

[0002] With the continuous development and progress of human society, problems caused by vibration are becoming increasingly widespread and numerous. Vibrations generated during our production and daily life constantly affect our lives and even threaten many buildings in our country that have extremely high cultural and historical value and significant humanistic significance. In particular, vibrations caused by construction or road work and traffic are vibrations. Vibration waves are vibrations that propagate in all directions from the vibration source, referring to elastic waves generated from the vibration source and radiating outwards. Existing foam-filled vibration isolation trenches, due to their concrete top cover, are susceptible to rainwater damage during operation, leading to foam material failure and consequently affecting the vibration isolation effect of the trench. Summary of the Invention

[0003] The purpose of this invention is to provide a foam-filled vibration isolation trench, which guides some rainwater through the slope and drain into a water storage tank for temporary storage. The collected rainwater is transported to an external water tank through a water pipe. Rainwater that seeps through the concrete roof is collected through a water collection trough and simultaneously transported to the inside of the water storage tank through a drain pipe, thus preventing rainwater from seeping into the vibration isolation trench assembly from inside the concrete roof and causing damage to the first and second foam layers.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a foam-filled vibration isolation trench, comprising a vibration isolation trench assembly, wherein a gravel layer is provided at the bottom of the vibration isolation trench assembly, a waterproof layer is provided inside the gravel layer, and a vibration isolation mechanism is provided on the vibration isolation trench assembly; The vibration isolation mechanism includes a backfill layer disposed inside the vibration isolation trench assembly. A first foam layer is disposed on both sides of the backfill layer, and a second foam layer is disposed on one side of each of the two sets of first foam layers. A support mechanism is disposed inside the vibration isolation mechanism. The support mechanism includes a concrete top plate installed on top of the vibration isolation trench assembly. Multiple sets of drainage pipes are installed inside the concrete top plate. One end of each set of drainage pipes is connected to a water storage tank. A water supply pipe is connected to one side of the water storage tank. A drain outlet is provided on the water storage tank. One end of the inclined surface of the concrete top plate is inserted into the drain outlet. One side of the water supply pipe is connected to an external water tank. The water supply pipe is installed in the middle of one side of the water storage tank. The movement inside the water storage tank is controlled by a vibration damping mechanism. The vibration damping mechanism includes two sets of drainage plates that move within a water storage tank. Multiple sets of movable sleeves are provided inside the two sets of drainage plates. Each set of movable sleeves contains a spring, and each spring has a movable support column at both ends. A movable plate is provided on one side of each set of drainage plates. The two sets of movable plates are fixedly connected to the support columns. The movable plate moves at the bottom of the concrete top slab, and one end of the movable plate passes through the water storage tank and connects to the drainage plate.

[0005] Preferably, a geotextile is laid on the outside of the vibration isolation trench component, the size of which is adapted to the vibration isolation trench component, and a drainage system is provided inside the gravel layer.

[0006] Preferably, a vibration isolation barrier is provided on the side of the vibration isolation trench assembly near the vibration source, the vibration isolation barrier is equidistant from the vibration isolation trench assembly, and the vibration isolation barrier is installed underground.

[0007] Preferably, the upper end of the concrete roof slab is provided with an inclined surface, the concrete roof slab is designed as a splice, a water collection trough is provided inside the concrete roof slab, and the two ends of the water collection trough are connected to multiple sets of drainage pipes.

[0008] Preferably, each of the two sets of support columns is provided with an extrusion plate on one side, one end of the extrusion plate is fixedly connected to a spring, and one end of the two sets of support columns is provided with a support plate, one end of the support plate is in contact with the outer wall of the vibration isolation trench assembly.

[0009] Preferably, the connection between the first foam layer and the second foam layer is made of flexible sealant.

[0010] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention guides some rainwater through the slope and drain into the water storage tank for temporary storage. The collected rainwater is transported to an external water tank through a water pipe. Rainwater that seeps through the concrete roof is collected through a water collection trough and simultaneously transported to the inside of the water storage tank through a drain pipe. This prevents rainwater from seeping into the vibration isolation ditch assembly from inside the concrete roof, thus avoiding damage to the first and second foam layers.

[0011] 2. This invention reflects the vibration waves through the rigid interface of the vibration isolation barrier, while the vibration waves that pass through the vibration isolation barrier quickly come into contact with the vibration isolation trench component, thereby reflecting and scattering the vibration waves, reducing the damage of the vibration waves to buildings around the vibration source, and improving the safety of buildings around the vibration source by compensating for the obstruction of low-frequency vibrations by the vibration isolation barrier and the vibration isolation trench component.

[0012] 3. This invention first consumes the vibration wave through a vibration isolation barrier, then consumes the transmitted vibration wave a second time through a first foam layer, then weakens the vibration wave again through a second foam layer, and finally consumes the vibration wave a last time through a hollow channel. By weakening the vibration wave multiple times, the impact of the vibration wave on the buildings around the vibration source is reduced.

[0013] 4. In this invention, rainwater in the water storage tank is discharged through the drain outlet when the drainage plate moves, and discharged onto the surface of the concrete roof slab to cool the surface of the concrete roof slab. At the same time, the discharged water re-enters the water storage tank through the slope of the concrete roof slab and the drain outlet for recycling. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] See Figures 1 to 9 As shown, the present invention provides a foam material-filled vibration isolation trench, including a vibration isolation trench assembly 1, a gravel layer 11 at the bottom of the vibration isolation trench assembly 1, a waterproof layer 12 inside the gravel layer 11, and a vibration isolation mechanism 2 on the vibration isolation trench assembly 1. The vibration isolation mechanism 2 includes a backfill layer 22 disposed inside the vibration isolation trench assembly 1, a first foam layer 23 disposed on both sides of the backfill layer 22, a second foam layer 24 disposed on one side of each of the two sets of first foam layers 23, and a support mechanism 3 disposed inside the vibration isolation mechanism 2. The support mechanism 3 includes a concrete top plate 31 installed on the top of the vibration isolation trench assembly 1. Multiple sets of drainage pipes 32 are installed inside the concrete top plate 31. One end of the multiple sets of drainage pipes 32 is connected to a water storage tank 33. A water supply pipe 34 is connected to one side of the water storage tank 33. The movement inside the water storage tank 33 is controlled by the vibration damping mechanism 4. The vibration damping mechanism 4 includes two sets of drainage plates 42 that move within the water storage tank 33. Multiple sets of movable sleeves 43 are provided inside the two sets of drainage plates 42. Each set of movable sleeves 43 is equipped with a spring 45, and each spring 45 has a movable support column 44 at both ends.

[0018] Workers used an excavator to dig vibration isolation trench component 1 at the required location. After digging, the inner walls on both sides of vibration isolation trench component 1 were compacted. After compaction, geotextile was laid on the inner side of vibration isolation trench component 1. After laying, gravel layer 11 was installed at the bottom of vibration isolation trench component 1. The gravel layer 11 was laid flat and the drainage system was installed inside the gravel layer 11. After installation, backfill layer 22, first foam layer 23, and second foam layer 24 were installed inside in sequence. In use, the vibration isolation barrier 21 is installed on the side close to the vibration source. The vibration waves generated at the vibration source first encounter the vibration isolation barrier 21. According to Newton's second law, it takes a very large force to make a massy object vibrate. Therefore, the vibration isolation barrier 21 can reflect a considerable portion of the vibration energy, especially low-frequency vibrations, by virtue of its inertia. The vibration waves are reflected by the rigid interface of the vibration isolation barrier 21, and some of the vibration waves that pass through the vibration isolation barrier 21 quickly come into contact with the vibration isolation trench component 1, thereby reflecting and scattering the vibration waves and reducing the damage of the vibration waves to buildings around the vibration source. The vibration isolation barrier 21 compensates for the obstruction of low-frequency vibrations by the vibration isolation trench component 1, thereby improving the safety of buildings around the vibration source.

[0019] Meanwhile, during rainy weather, the slope of the concrete roof slab 31 guides the rainwater falling on it. Some of the rainwater enters the water storage tank 33 through the slope and the drain outlet 36 for temporary storage. As the amount of rainwater entering the water storage tank 33 increases with rainfall, when the rainwater in the water storage tank 33 overflows one end of the water supply pipe 34, the collected rainwater is transported to an external water tank through the water supply pipe 34 for collection and utilization. At the same time, since the concrete roof slab 31 is made of concrete, some rainwater may easily enter the vibration isolation trench component 1 through the concrete during operation. The water collection trough 35 collects the rainwater that seeps through the concrete roof slab 31 and transports it to the inside of the water storage tank 33 through the drain pipe 32, preventing rainwater from seeping into the vibration isolation trench component 1 from inside the concrete roof slab 31 and causing damage to the first foam layer 23 and the second foam layer 24.

[0020] Simultaneously, when vibration occurs, the vibration is transmitted to the inside of the vibration isolation trench assembly 1, causing the support plate 46 to vibrate. The vibration of the support plate 46 drives the support column 44 to move, which in turn drives the movable plate 41 to move. The movable plate 41 then drives the drainage plate 42 to move. At the same time, the movement of the support column 44 drives the extrusion plate 47 to move, which in turn compresses the spring 45. The spring 45 then retracts and retracts to reset the vibration of the extrusion plate 47. By installing the water supply pipe 34 in the middle of the water storage tank 33, half of the rainwater inside the water storage tank 33 is prevented from being discharged through the water supply pipe 34. Meanwhile, when the drainage plate 42 moves, it discharges the rainwater in the water storage tank 33 through the drainage outlet 36 onto the surface of the concrete roof slab 31 to cool the surface of the concrete roof slab 31. The discharged water then returns to the water storage tank 33 through the slope of the concrete roof slab 31 and the drainage outlet 36 for recycling.

[0021] Simultaneously, during the transmission of vibration waves, the vibration waves are first attenuated by the vibration isolation barrier 21. After passing through the vibration isolation barrier 21, the vibration waves are secondally attenuated by the first foam layer 23. The vibration waves entering the first foam layer 23 have a lower wave resistance than the ground, thus weakening the vibration waves transmitted into the first foam layer 23. The vibration waves passing through the first foam layer 23 then enter the second foam layer 24, where the wave resistance is lower than that of the first foam layer 23, further weakening the vibration waves. Finally, the vibration waves are transmitted to the empty trench inside the vibration isolation trench component 1, where they are attenuated for the last time. Through multiple weakening processes, the vibration waves are reduced, thus mitigating their impact on buildings surrounding the vibration source.

[0022] In an optional embodiment, a geotextile is laid on the outside of the vibration isolation trench assembly 1, the size of which is adapted to the vibration isolation trench assembly 1, and a drainage system is provided inside the gravel layer 11.

[0023] It should be noted that during the operation, the geotextile guides the water seeping into the soil outside the vibration isolation trench component 1, allowing the seeping water to pass through the geotextile while being isolated by the waterproof layer 12. The water then enters the gravel layer 11, where it is discharged through the drainage system, preventing water from accumulating on the outside of the waterproof layer 12. Over a long period of operation, the increased accumulation of water increases the pressure on the waterproof layer 12, causing damage to it and consequently affecting the first foam layer 23, thus reducing its ability to block vibration waves.

[0024] In an optional embodiment, a vibration isolation barrier 21 is provided on the side of the vibration isolation trench assembly 1 near the vibration source. The vibration isolation barrier 21 is equidistant from the vibration isolation trench assembly 1 and is installed underground.

[0025] It should be noted that by installing the vibration isolation barrier 21 on the side close to the vibration source, the vibration waves generated at the vibration source first encounter the vibration isolation barrier 21. The vibration isolation barrier 21, due to its inertia and mass, first reflects away a considerable portion of the vibration energy, especially low-frequency vibrations. Furthermore, some of the vibration waves are reflected through the rigid interface of the vibration isolation barrier 21. At the same time, some of the vibration waves that pass through the vibration isolation barrier 21 quickly come into contact with the vibration isolation trench component 1, thereby reflecting and scattering the vibration waves, reducing the damage of the vibration waves to buildings around the vibration source. The vibration isolation barrier 21 compensates for the obstruction of low-frequency vibrations by the vibration isolation trench component 1, thereby improving the safety of buildings around the vibration source.

[0026] In an optional embodiment, the upper end of the concrete roof slab 31 is provided with a slope, the concrete roof slab 31 is designed to be spliced, and a water collection trough 35 is provided inside the concrete roof slab 31. The two ends of the water collection trough 35 are connected to multiple sets of drainage pipes 32.

[0027] It should be noted that, since the concrete roof slab 31 is made of concrete, some rainwater may easily enter the vibration isolation ditch assembly 1 through the concrete during operation. The rainwater that seeps through the concrete roof slab 31 is collected by the water collection trough 35 and transported to the water storage tank 33 through the drainage pipe 32. This prevents rainwater from seeping into the vibration isolation ditch assembly 1 through the concrete roof slab 31 and causing damage to the first foam layer 23 and the second foam layer 24.

[0028] In an optional embodiment, the water storage tank 33 is provided with a drain outlet 36, one end of the inclined surface of the concrete top slab 31 is inserted into the drain outlet 36, and one side of the water supply pipe 34 is connected to an external water tank. The water supply pipe 34 is installed in the middle of one side of the water storage tank 33.

[0029] It should be noted that during rainy days, the slope of the concrete roof slab 31 guides the rainwater falling on the concrete roof slab 31. Some of the rainwater enters the water storage tank 33 through the slope and the drain outlet 36 for temporary storage. At the same time, the amount of rainwater entering the water storage tank 33 increases with the rainfall. When the rainwater in the water storage tank 33 overflows one end of the water supply pipe 34, the collected rainwater is transported to an external water tank through the water supply pipe 34 for collection and utilization.

[0030] In an optional embodiment, each of the two sets of drainage boards 42 is provided with a movable plate 41 on one side. The two sets of movable plates 41 are fixedly connected to the support column 44 respectively. The movable plate 41 moves at the bottom of the concrete top slab 31. One end of the movable plate 41 passes through the water storage tank 33 and is connected to the drainage board 42.

[0031] It should be noted that the movement of the support column 44 causes the movable plate 41 to move, and the movement of the movable plate 41 causes the drainage plate 42 to move. When the drainage plate 42 moves, the rainwater in the water storage tank 33 is discharged through the drainage outlet 36 and discharged onto the surface of the concrete roof slab 31 to cool the surface of the concrete roof slab 31. At the same time, the discharged water is recycled back into the water storage tank 33 through the slope of the concrete roof slab 31 and the drainage outlet 36.

[0032] In an optional embodiment, each of the two sets of support columns 44 is provided with a pressing plate 47 on one side, one end of the pressing plate 47 is fixedly connected to the spring 45, and one end of each of the two sets of support columns 44 is provided with a support plate 46, one end of the support plate 46 is in contact with the outer wall of the vibration isolation trench assembly 1.

[0033] It should be noted that the vibration is transmitted to the inside of the vibration isolation trench assembly 1, causing the support plate 46 to vibrate. The vibration of the support plate 46 drives the support column 44 to move. At the same time, the movement of the support column 44 drives the extrusion plate 47 to move. The movement of the extrusion plate 47 compresses the spring 45. The vibration of the extrusion plate 47 is reset by the extension and retraction of the spring 45.

[0034] In an optional embodiment, the connection between the first foam layer 23 and the second foam layer 24 is made of flexible sealant.

[0035] It should be noted that the connection between the first foam layer 23 and the second foam layer 24 is sealed with flexible sealant to prevent the formation of sound bridges due to gaps at the connection between the first foam layer 23 and the second foam layer 24 during operation, which would allow vibration waves to pass through quickly and reduce the effectiveness of the device.

[0036] Working principle: When in use, the vibration isolation barrier 21 is installed on the side close to the vibration source. The vibration wave generated at the vibration source first encounters the vibration isolation barrier 21. A portion of the vibration energy is reflected by the vibration isolation barrier 21, and part of the vibration wave is reflected by the rigid interface of the vibration isolation barrier 21. At the same time, part of the vibration wave that passes through the vibration isolation barrier 21 quickly comes into contact with the vibration isolation groove component 1, thereby reflecting and scattering the vibration wave.

[0037] Meanwhile, during rainy weather, the slope of the concrete roof slab 31 guides the rainwater falling on it. Some of the rainwater enters the water storage tank 33 through the slope and the drain outlet 36 for temporary storage. As the amount of rainwater entering the water storage tank 33 increases with rainfall, when the rainwater in the water storage tank 33 overflows one end of the water supply pipe 34, the collected rainwater is transported to an external water tank through the water supply pipe 34. At the same time, since the concrete roof slab 31 is made of concrete, some rainwater may easily enter the vibration isolation ditch assembly 1 through the concrete during operation. The rainwater passing through the concrete roof slab 31 is collected by the water collection trough 35 and transported to the inside of the water storage tank 33 through the drain pipe 32.

[0038] Simultaneously, when vibration occurs, the vibration is transmitted to the inside of the vibration isolation trench assembly 1, causing the support plate 46 to vibrate. The vibration of the support plate 46 drives the support column 44 to move, the movement of the support column 44 drives the movable plate 41 to move, the movement of the movable plate 41 drives the drainage plate 42 to move, and at the same time, the movement of the support column 44 drives the extrusion plate 47 to move. The movement of the extrusion plate 47 extrudes the spring 45. By installing the water supply pipe 34 in the middle of the water storage tank 33, it is ensured that half of the rainwater inside the water storage tank 33 will not be discharged through the water supply pipe 34. At the same time, when the drainage plate 42 moves, it discharges the rainwater in the water storage tank 33 through the drainage outlet 36 and discharges it onto the surface of the concrete roof slab 31.

[0039] Simultaneously, during the transmission of vibration waves, the vibration waves are first attenuated by the vibration isolation barrier 21. After passing through the vibration isolation barrier 21, the vibration waves are secondally attenuated by the first foam layer 23. The vibration waves entering the first foam layer 23 have a lower wave resistance than the soil, thus weakening the vibration waves transmitted into the first foam layer 23. The vibration waves passing through the first foam layer 23 then enter the second foam layer 24. The wave resistance of the second foam layer 24 is lower than that of the first foam layer 23, further weakening the vibration waves. Finally, the vibration waves are transmitted into the empty trench inside the vibration isolation trench assembly 1.
