The bamboo net serves as a reinforced material to be arranged in the earth embankment, under the impact load, the high tensile strength of bamboo and the compression resistance of the soil body are organically combined, the load is effectively transmitted and diffused to the whole earth embankment section through bamboo-soil interface friction, all the soil body materials participate in force bearing, and the utilization rate and integrity of the earth embankment are greatly improved. The system dissipates energy through multiple mechanisms such as elastic deformation of bamboo wood, friction slippage of bamboo ribs and a soil body, plastic compaction of the soil body and the like.

Description

Technical Field

[0001] This invention relates to the field of blasting engineering technology, specifically to a bamboo vibration damping structure and its construction method. Background Technology

[0002] When demolishing high-rise reinforced concrete structures such as power generation towers, chimneys, and tall buildings by blasting, the huge peak impact load generated when the structure hits the ground will not only cause strong ground vibrations, leading to cracks in the foundations of surrounding buildings and damage to pipelines, but also be accompanied by a large number of debris flying around, seriously threatening personnel safety and environmental safety.

[0003] Among existing protective technologies, traditional earthen embankments / sand mound buffer schemes rely on the energy dissipation of soil compaction deformation, which has three major defects: First, the tensile strength of the soil is extremely low, and it is prone to local shear failure under impact, making it difficult to spread the load. Only the surface soil participates in bearing the load, and the material utilization rate is less than 30%. Second, the vibration reduction mechanism is simple, relying solely on the energy dissipation of soil plastic compaction, resulting in low buffering efficiency and difficulty in resisting high-intensity impacts. Third, the overall integrity is poor, and it is prone to collapse after impact, failing to effectively restrain the splashing of debris.

[0004] To address these issues, the industry has attempted to adopt improved solutions such as reinforced earthen embankments with metal mesh and rubber mats, but significant shortcomings remain: metal mesh is expensive (costing over 3,000 yuan per ton of steel) and is prone to rust and breakage under repeated impacts, resulting in insufficient durability; while rubber mats offer better cushioning, their unit price is as high as 80-150 yuan / ㎡, making large-scale application uneconomical, and they are prone to aging and failure after high temperatures or prolonged sun exposure, making them difficult to recycle. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of low buffering efficiency of traditional soil-lift buffer layers and high cost of materials such as rubber pads, and to propose a bamboo vibration reduction structure and construction method.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A bamboo vibration damping structure, comprising: At least two earthen embankments are set up sequentially from the bottom of the structure along the predetermined collapse direction of the structure, and the height of the earthen embankments increases sequentially along the predetermined collapse direction of the structure; the height of the earthen dikes increases in a step-like manner along the collapse direction. A bamboo frame is installed inside the embankment. The bamboo composite frame is built into the embankment and has a multi-layer three-dimensional grid structure, including vertical support bamboo, horizontal main load-bearing bamboo, and horizontal connecting bamboo. The dual protection system includes an inner layer of bamboo woven mesh and a surface layer of HDPE dense mesh protective mesh. The top buffer layer is laid on the top of the outermost embankment.

[0008] As a further aspect of the present invention: the bamboo frame comprises: Vertical support bamboo is used, with one end vertically inserted into the soil layer; the vertical support bamboo is selected from anti-corrosion treated moso bamboo with a diameter of 14-18cm, and is vertically inserted 1.8-2.5m below the foundation, with an insertion spacing of 1.2-1.5m, and the holes are backfilled and compacted with graded crushed stone and cement slurry. The horizontal main load-bearing bamboo is set horizontally on the vertical support bamboo; the horizontal main load-bearing bamboo has a diameter of 11-14cm, is arranged perpendicular to the direction of collapse, and is fixed through the first through hole on the vertical support bamboo, with a layer spacing of 0.6-0.8m, and the nodes are double-tied with bamboo strips and stainless steel wire. Horizontal connecting bamboo is longitudinally arranged on the horizontal main load-bearing bamboo; the horizontal connecting bamboo has a diameter of 8-10cm, is arranged parallel to the collapse direction, and is fixed through the second through hole on the horizontal main load-bearing bamboo to form a horizontal grid of 1.2-1.5m×1.2-1.5m.

[0009] As a further aspect of the present invention: the horizontal main load-bearing bamboo is perpendicular to the predetermined collapse direction of the structure.

[0010] As a further aspect of the present invention: the horizontal connecting bamboo is parallel to the predetermined collapse direction of the structure.

[0011] As a further aspect of the present invention: a first through hole is provided on the vertical support bamboo corresponding to the horizontal main load-bearing bamboo, and the end of the horizontal main load-bearing bamboo passes through the first through hole through the vertical support bamboo.

[0012] As a further aspect of the present invention: a second through hole is provided on the horizontal main load-bearing bamboo corresponding to the horizontal connecting bamboo, and the end of the horizontal connecting bamboo passes through the second through hole through the horizontal main load-bearing bamboo.

[0013] As a further embodiment of the present invention: the bamboo vibration damping structure further includes a surface protective net, wherein the horizontal connecting bamboo and the horizontal main load-bearing bamboo are fixed to form a horizontal grid, the surface protective net is laid on the horizontal grid, the inner bamboo woven mesh has a mesh size of 5-8cm and is laid on each layer of the horizontal grid; the surface HDPE dense mesh protective net has a mesh size of ≤2cm, covers the slope and edge of the earthen embankment, and is embedded 0.3m into the earthen embankment.

[0014] As a further aspect of the present invention: a buffer layer is also laid on the top of the soil embankment, the buffer layer being composed of a polymer buffer material; the thickness of the top buffer layer is 0.3-0.5m, and it is made of alternating layers of waste tire pieces and polymer buffer foam, with the tire pieces filled with rubber particles and fixed to the bamboo frame.

[0015] As a further aspect of the present invention: the diameter of the vertical support bamboo is greater than the diameter of the horizontal main load-bearing bamboo.

[0016] A construction method for a bamboo vibration damping structure includes the following steps: Step 1: Foundation treatment and vertical support bamboo positioning The construction site was leveled, and then the locations of the vertical support bamboo insertion points were determined according to the design spacing. Step 2: Install the vertical support frame Vertical support bamboo is vertically implanted at the implantation point determined in step 1, and the implantation depth of the vertical support bamboo meets the vertical bearing requirements; the holes after the vertical support bamboo is implanted are backfilled with graded crushed stone or concrete and the backfill material is fully compacted to enhance the embedding effect of the roots of the vertical support bamboo and ensure its vertical stability. Step 3: Construct a layered bamboo mesh frame with built-in space On the vertical support bamboo, horizontal main load-bearing bamboo is fixed in layers according to the design elevation; the horizontal main load-bearing bamboo is set to be parallel to the ground and perpendicular to the collapse direction; the horizontal main load-bearing bamboo is firmly tied to the vertical support bamboo at the binding and fixing points using binding devices; On the fixed horizontal main load-bearing bamboo, installation holes are made at the designed intervals, and horizontal connecting bamboo is passed through the installation holes to form a horizontal grid; the horizontal connecting bamboo is set in a direction parallel to the collapse direction; Step 4: Laying the surface protective netting and filling the slope A protective net is laid on the bottom surface of each layer of bamboo mesh frame constructed in step 3, and the edges of the protective net are tied and fixed to the bamboo mesh frame; The soil slope material is backfilled in layers. When each layer of soil slope material is backfilled to the height of the corresponding bamboo mesh frame, the backfilled soil slope material is compacted to ensure that the soil is in close contact with the bamboo mesh frame. The above backfilling and compaction steps are repeated until the soil slope material is filled to the design elevation, so that each layer of bamboo mesh reinforcement is completely embedded in the soil slope. Step 5: Lay the buffer layer The remaining soil was backfilled and compacted to the design elevation, and then a buffer layer was laid on the top surface of the slope. The buffer layer was composed of materials with vibration damping and buffering functions. Finally, the entire slope was compacted to form a complete bamboo vibration damping structure.

[0017] In soft soil foundation conditions, the spacing of vertical support bamboo planting is increased to 0.8-1.0m, and the planting depth is increased to 2.0-2.5m. The foundation is reinforced with graded crushed stone (depth 0.5-1.0m) + geogrid.

[0018] The beneficial effects of this invention are: 1. Created a highly efficient "bamboo-soil composite load-bearing body": This invention incorporates bamboo mesh as a reinforcing material into the earthen embankment. Under impact loads, the high tensile strength of bamboo and the compressive strength of the soil are organically combined. Through the friction of the bamboo-soil interface, the load is effectively transferred and diffused to the entire cross-section of the earthen embankment, so that all soil materials participate in load bearing, which greatly improves the utilization rate and integrity of the earthen embankment.

[0019] 2. Achieves graded and efficient energy dissipation: The system dissipates energy through multiple mechanisms, including the elastic deformation of bamboo itself, frictional slippage between bamboo reinforcements and soil, and plastic compaction of the soil. The excellent toughness of bamboo ensures that the reinforcement layer remains continuous after undergoing large deformations, thus continuously playing a role in tying and load diffusion, preventing the brittle collapse of the embankment.

[0020] 3. Outstanding comprehensive protective performance: The built-in bamboo net and the dense mesh protective net together form a dual protection system, which effectively restrains the disintegration and splashing of the earthen embankment under impact, and improves safety and environmental friendliness.

[0021] 4. Economic efficiency and sustainability: This solution makes full use of the characteristics of bamboo as a renewable, low-cost, and excellent mechanical material. The structure is reasonable and the construction is convenient, providing an excellent solution for similar projects in bamboo-rich areas. Attached Figure Description

[0022] The invention will now be further described with reference to the accompanying drawings.

[0023] Figure 1 This is a schematic diagram showing the positions of the soil embankment and the blasted debris during the implementation of this invention; Figure 2 This is the front view of the bamboo frame; Figure 3 This is a top view of the bamboo frame.

Horizontal main load-bearing bamboo; 7. Horizontal connecting bamboo; 8. Surface protective netting; 9. Binding and fixing points; 10. Buffer layer; Detailed Implementation The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Compared to existing technologies, bamboo, as a natural, high-performance bio-based material, possesses unique mechanical advantages and environmentally friendly properties, and its application potential in engineering protection has not yet been fully explored. Bamboo has an extremely high strength-to-weight ratio; its tensile strength can reach over 250 MPa, surpassing many ordinary steels. Simultaneously, it exhibits excellent toughness and bending properties, high failure strain, and can withstand large deformations without brittle fracture, making it an ideal energy-absorbing material. Under impact loads, bamboo fibers effectively dissipate a large amount of energy through self-stretching, slippage, and rearrangement. Furthermore, bamboo has a short growth cycle and is a renewable green resource, aligning with the concept of sustainable development. Therefore, this application uses bamboo as the main framework, pre-embedded within the soil layer to enhance its buffering effect.

[0026] A bamboo vibration damping structure, comprising: At least two earthen mounds are set up sequentially along the predetermined collapse direction of the structure, starting from the bottom of the structure, and the height of the earthen mounds increases sequentially along the predetermined collapse direction of the structure; The height of the earthen embankment increases in a stepped manner (the height difference between adjacent earthen embankments is 0.8-1.5m), the slope of the earthen embankment is 1:1.5-1:2.0, and it is filled with graded sand and gravel soil (containing 20%-30% gravel) to ensure that the compaction density of the soil is ≥1.8g / cm³. exist Figure 1 There are 3 earthen slopes in total: the near-tower section earthen slope 2, the middle section earthen slope 3, and the far section earthen slope 4. The 3 earthen slopes are set up in sequence along the collapse direction of the blasted collapse object 1. A bamboo frame is installed inside the earthen embankment; Figure 2 and Figure 3 These are all demonstrations of bamboo frame structures, which include: One end of the vertical support bamboo 5 is vertically inserted into the soil layer. Because a frame needs to be built, the number of vertical support bamboo 5 should not be less than 4. Vertical support bamboo: Select three-year-old or older moso bamboo with a diameter of 14-18cm. One end is vertically inserted into the ground 1.8-2.5m below the foundation (the insertion depth is not less than 1 / 3 of the height of the embankment). The insertion spacing is 1.2-1.5m. The surface of the bamboo is coated with environmentally friendly anti-corrosion coating (containing a composite coating of bamboo charcoal powder and tung oil) to enhance its corrosion resistance. The horizontal main load-bearing bamboo 6 is horizontally arranged on the vertical support bamboo 5, and there shall be at least 2 horizontal main load-bearing bamboo 6. The horizontal connecting bamboo 7 is set longitudinally on the horizontal main load-bearing bamboo 6. There must be at least two horizontal connecting bamboo 7s to build a frame. The horizontal main load-bearing bamboo 6, the vertical support bamboo 5 and the horizontal connecting bamboo 7 are all made of bamboo, and the three can be fixed together by binding with straps. The horizontal main load-bearing bamboo 6 is made of moso bamboo with a diameter of 11-14cm. It is laid horizontally perpendicular to the intended collapse direction of the structure and fixed through the first through hole opened on the vertical support bamboo (the hole diameter is 5-8mm larger than the diameter of the horizontal main load-bearing bamboo). The layer spacing is 0.6-0.8m. The connection with the vertical support bamboo is fixed by double binding with bamboo strips and stainless steel wire.

[0027] After the horizontal connecting bamboo 7 is fixed to the horizontal main load-bearing bamboo 6, a horizontal grid similar to a platform will be formed. Then, by sequentially building the horizontal connecting bamboo 7 from bottom to top, multiple horizontal grids will be formed. Horizontal connecting bamboo: Bamboo with a diameter of 8-10cm is selected and laid longitudinally parallel to the intended collapse direction of the structure. It is fixed by passing through the second through hole opened on the horizontal main load-bearing bamboo. The hole diameter is 3-5mm larger than the diameter of the horizontal connecting bamboo, forming a horizontal grid of 1.2m×1.2m-1.5m×1.5m. The nodes are double-fixed using bamboo glue. For better buffering effect, protective netting 8 can be laid on the horizontal grid of each layer. This can separate the soil in the soil embankment into layers and prevent collapse after the soil layers are piled up too high. High-density polyethylene (HDPE) dense mesh protective netting (aperture ≤2cm) is used to cover the top surface of each layer of bamboo woven netting and is firmly tied to the bamboo frame to prevent debris from flying and soil loss.

[0028] Finally, a buffer layer 10 can be laid on top of the embankment. The buffer layer 10 can be made of polymer buffer material, specifically waste tires. The buffer layer 10 is laid on the top of the outermost embankment, with a thickness of 0.3-0.5m. It is made by alternately laying waste tire pieces with a size of 20cm×20cm×10cm and polymer buffer foam, with rubber particles filling the spaces between the tire pieces to improve the impact buffering effect.

[0029] A construction method for a bamboo vibration damping structure includes the following steps: Taking the construction of a 5-meter-high earthen embankment during the demolition of a power generation tower as an example, the invention will be described in detail below: 1. Foundation treatment and vertical support bamboo positioning: Level the site and determine the planting points of the vertical support bamboo according to the design spacing.

[0030] 2. Install vertical support frame: Vertically insert bamboo poles with a diameter of 14-16cm at the insertion point as vertical support bamboo, with an insertion depth of ≥1.8 meters. Backfill the hole with graded crushed stone or concrete and tamp it thoroughly to enhance the root embedment conditions and ensure vertical stability.

[0031] 3. Layered construction of the built-in spatial bamboo mesh frame On the vertical support bamboo, fix the horizontal main load-bearing bamboo in layers according to the design elevation. The horizontal main load-bearing bamboo should be made of bamboo poles with a diameter of 11-13cm, parallel to the ground and perpendicular to the direction of collapse. Use high-strength ropes or bamboo strips to securely tie them to the vertical support bamboo at the binding points.

[0032] Drill holes at predetermined intervals on the fixed horizontal main load-bearing bamboo, and pass horizontal connecting bamboo with a diameter of 8-10cm through the holes to form a horizontal grid. The direction of the horizontal connecting bamboo is parallel to the direction of collapse.

[0033] 4. Laying surface protective netting and constructing earthen embankments A dense protective net is laid on the bottom of each layer of bamboo netting, and its edges are tied and fixed to the bamboo netting.

[0034] The soil embankment material is backfilled in layers. Each layer is fully compacted when it reaches the height of the bamboo mesh to ensure that the soil and the bamboo mesh are in close contact. This process is repeated until the design elevation is reached, so that the bamboo mesh reinforcement layer is completely embedded in the soil embankment.

[0035] 5. Lay a buffer layer The remaining soil is backfilled and compacted to the design elevation. Then, a buffer layer, mainly composed of waste tires or high-performance engineering foam, is laid on the top surface. Finally, the entire embankment is filled and compacted to form a complete vibration reduction structure.

[0036] For special working conditions such as ponds and swamps with low bearing capacity and difficult construction, this invention provides a simplified bamboo-soil vibration reduction structure implementation scheme: 1. Densified deployment of vertical hollow vibration damping bamboo: In the backfilled embankment area, vertical support bamboo is driven vertically and densely into the soft soil foundation at intervals of 0.2 to 0.5 meters to form a group of "hollow vibration damping holes". The implantation depth needs to be significantly increased to ensure anchorage in the deep stable layer.

[0037] 2. Construct segmented earthen embankments: In this hollow vibration-damping bamboo grove, construct segmented gradient earthen embankments as normal.

[0038] In this scheme, the dense vertical support bamboo grove creatively utilizes the natural hollow tubular structure of bamboo as vibration damping holes through its energy dissipation during breakage and the effect of pile foundation. This effectively attenuates the impact force and improves the foundation conditions. The structure is simple and suitable for soft soil areas where large machinery cannot easily access.

[0039] Another method for constructing bamboo vibration damping structures includes the following steps: 1. Foundation treatment and positioning: Clear debris from the construction site and replace the soft soil foundation with graded crushed stone (replacement depth 0.5-1.0m) to ensure the foundation bearing capacity is ≥120kPa; Use a total station to locate the planting points of the vertically supporting bamboo according to the designed spacing. At the planting points, dig guide holes with a diameter of 20-25cm, and the hole depth is 0.1m deeper than the planting depth.

[0040] 2. Installation of vertical support bamboo: After applying the anti-corrosion coating, vertically insert the bamboo support into the guide hole, with the top exposed at the designed height. Backfill the hole with graded crushed stone and cement slurry (water-cement ratio 1:0.5), and compact it in layers (each layer ≤0.3m thick) to ensure that the verticality deviation of the bamboo support is ≤3‰ and the top elevation error is ≤±5cm.

[0041] 3. Bamboo composite frame construction: According to the design elevation, make the first through hole on the vertical support bamboo, pass the horizontal main load-bearing bamboo through the through hole, wrap it with bamboo strips (2-3cm wide) 3-4 times, and then tie it with stainless steel wire (1.2mm in diameter) for fixation. The spacing between the binding points should be ≤0.3m. Make a second through hole at the designed interval on the horizontal main load-bearing bamboo, insert the horizontal connecting bamboo, apply bamboo glue to the node and tie it to fix it to form a horizontal grid, thus completing the construction of a single-layer frame. Repeat the above steps according to the layer spacing until the framework of all layers is completed.

[0042] 4. Installation of protective netting and construction of earthen embankments: Lay an inner layer of bamboo mesh on each horizontal grid, then lay the edge of each layer of HDPE close-mesh protective netting and tie it to the bamboo frame (tying point spacing ≤ 0.5m). Then backfill with graded sand and gravel in layers, each layer with a thickness of 0.3-0.4m. Use a small vibratory roller (weight 1.5-2.0t) to compact it, with a compaction degree ≥ 95%, to ensure that the soil is in close contact with the bamboo frame. After the earthen embankment slope is formed, a surface layer of HDPE dense mesh protective netting is laid, with the edges embedded 0.3m into the earthen embankment. The spacing between the binding points on the slope is ≤0.8m to ensure that the protective netting is flat and not loose.

[0043] 5. Laying and finishing the top buffer layer: Backfill the remaining soil to the design elevation, compact it, and then lay the top buffer layer. First, lay a layer of polymer buffer foam, then place the waste tire pieces, fill the spaces between the tire pieces with rubber granules, and finally use stainless steel wire to fix the tire pieces to the bamboo frame. The entire earthen embankment was finally compacted (compaction degree ≥96%), the integrity of the bamboo frame and the fixation of the protective net were checked, and the construction was completed.

[0044] Example 1: Vibration reduction project for the demolition of a power generation tower (conventional foundation) 1. Engineering parameters: The power generation tower is 80m high and weighs about 1200t. The planned collapse direction is 30m long. The design includes a three-level earthen embankment (2m high near the tower, 3.5m high in the middle section, and 5m high in the far section). The total length of the earthen embankment is 25m and the width is 15m.

[0045] 2. Material selection: Vertical support bamboo: 16cm diameter moso bamboo, planted at a depth of 2.2m and a spacing of 1.3m; Horizontal main load-bearing bamboo: 12cm diameter moso bamboo, with a layer spacing of 0.7m; Horizontal connecting bamboo: 9cm diameter moso bamboo, grid size 1.3m × 1.3m; Buffer layer: Cut pieces of waste tires (20cm×20cm×10cm) are laid on top of EVA cushioning foam.

[0046] 3. Key points of construction: The foundation was replaced with 0.8m of graded crushed stone, achieving a bearing capacity of 130kPa; The backfill for vertical support bamboo uses graded crushed stone + cement grout, with a compaction density ≥1.9g / cm³; After each layer of earthen embankment filling is compacted, the compaction degree is tested using the ring cutter method to ensure ≥95%; The distance between the binding points of the protective netting and the bamboo frame is 0.6m to prevent loosening.

[0047] Example 2: Vibration reduction project for chimney blasting on soft soil foundation (special working conditions) 1. Project parameters: The chimney is 60m high and weighs about 800t. The construction site is a soft soil foundation backfilled from a pond (bearing capacity 80kPa). The design includes a Class 2 earthen embankment (2.5m high in the near section and 4m high in the far section), with a total length of 20m and a width of 12m.

[0048] 2. Structural adjustment: Vertical support bamboo is densely arranged with a spacing of 0.8m, a diameter of 18cm, and an implantation depth of 2.5m (anchored to a deep stable soil layer). The horizontal grid size was reduced to 1.0m × 1.0m; The foundation was replaced with 1.0m of graded crushed stone, and geogrid (tensile strength ≥50kN / m) was laid to enhance the overall integrity.

[0049] 3. Key points of construction: The vertical support bamboo was planted using a static pressure method to avoid disturbing the soft soil foundation; The earthen embankment was constructed using a light roller (weighing 1.5t) for layered compaction, with each layer being 0.3m thick. The top buffer layer is thickened to 0.5m, and the tire block density is increased by 30%.

[0050] 4. Vibration reduction effect: The peak impact load of the chimney upon ground contact is reduced to 1800kN, the ground vibration velocity is 0.6cm / s, the embankment has no lateral displacement, and the foundation settlement is ≤3cm, meeting the construction requirements for soft soil foundations.
