Description

Technical Field

[0001] This invention belongs to the field of cushioning material technology, and relates to a general-purpose building cushioning structural component, processing device and processing method. Background Technology

[0002] In the field of building engineering, buffer structural components are a type of core component with comprehensive functions of load bearing, buffering, and energy dissipation. Their core function is to absorb adverse effects such as seismic loads, impact loads (such as rockfalls, vehicle collisions, and construction impacts), and structural deformation stresses (such as surrounding rock convergence and temperature deformation) through their own structural or material properties, thereby reducing the transfer of loads to the main building structure, preventing cracking, damage, or failure of the main structure, and ensuring the safety and durability of the building project.

[0003] The application scenarios of such components cover many sub-fields in the construction field: in underground engineering, it is necessary to deal with the damage to the support structure caused by the deformation of the surrounding rock of the tunnel and the impact load; in high-rise buildings, it is necessary to mitigate the relative deformation of the floor slab and the wall under the action of earthquake and reduce the risk of structural cracking; in building curtain wall engineering, it is necessary to buffer the impact of wind load and temperature stress on the connection nodes between the curtain wall and the main structure; in bridge engineering, it is necessary to reduce the wear of bridge bearings caused by the vibration generated by vehicle traffic; in interior decoration and public buildings, it is necessary to achieve buffering needs such as collision protection and noise reduction.

[0004] However, existing buffer components in the construction field have significant limitations:

[0005] 1. Traditional buffer components are mostly designed for specific scenarios, such as PVC secondary lining pipes for tunnels, metal buffer components for building curtain walls, and rubber bearings for bridges. There is a lack of universal products that can be adapted to different scenarios. The highly targeted design of specialized components makes it difficult to meet the differentiated requirements of different building scenarios for buffer strength, size, waterproofing, and durability. This leads to the need to purchase multiple types of components in the project, increasing procurement and construction management costs.

[0006] 2. Traditional rigid cushioning components (such as metal alloy parts, PVC / PE / MPP rigid pipes, and ABS components) have high raw material unit prices, leading to a surge in engineering costs when used on a large scale. Furthermore, rigid components require significant space for transportation and storage and are prone to damage from impacts, further increasing expenses. Meanwhile, while some flexible cushioning components (such as simple rubber pads and ordinary woven bag packaging) are lower in cost, they suffer from insufficient strength, poor waterproofing, and weak tensile strength, making them prone to aging and damage with prolonged use, requiring frequent replacement and maintenance.

[0007] 3. Traditional rigid buffer components are highly rigid but have limited strain capacity. When encountering dynamic loads such as earthquakes or structural deformation, they are unable to absorb energy through their own deformation, easily leading to the direct transfer of load to the main structure. While traditional flexible buffer components have strong deformation capacity, their load-bearing strength is insufficient, and they are prone to excessive deformation or failure under large loads, failing to meet the load-bearing requirements of building structures. In addition, some buffer components have poor compatibility with building materials (such as concrete and mortar), and long-term use can easily lead to interface delamination, affecting the overall support or connection effect.

[0008] Therefore, in response to the core requirements of universal adaptability, low cost, high strength, strong buffering and good durability of buffer components in different scenarios in the construction field, this invention designs a universal buffer structure component, processing device and processing method for buildings to solve the shortcomings of the prior art. Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings of the prior art and provide a general-purpose building buffer structure component, processing device and processing method.

[0010] The technical solution adopted by this invention to solve its technical problem is:

[0011] A general-purpose building buffer structure component, characterized in that it comprises a waterproof woven bag and a foamed concrete core poured and molded inside the waterproof woven bag, wherein the waterproof woven bag includes a nylon bag and a waterproof material disposed on the outside of the nylon bag; the foamed concrete core is a buffer structure component formed by pouring mixed foamed concrete into the waterproof woven bag, and the filling density of the foamed concrete inside the waterproof woven bag is 500 kg / m³. 3 The buffer structure component has the support strength for the building foundation and the characteristics of buffer strain. The yield strength of the buffer structure component is 12.97kN-17.73kN, and the strain corresponding to the yield strength is 1.3%-2.1%.

[0012] Furthermore, the nylon bag is woven from nylon yarn, and crisscrossing reinforcing lines are also woven into the nylon bag. These reinforcing lines form the reinforcing ribs of the nylon bag. The strength of the nylon bag is 60-80KN, the deformation degree is 15%, and the permeability is 2%-3%.

[0013] Furthermore, the waterproof material is PE material, which is coated onto the outer surface of the nylon bag by thermal bonding.

[0014] A processing device for a general-purpose building buffer structure component includes a construction platform, a waterproof woven bag fixing mechanism, and a mobile grouting mechanism. The construction platform is erected on the ground by columns, the waterproof woven bag fixing mechanism is laid on the platform, and the mobile grouting mechanism is movably installed on the upper end of the waterproof woven bag fixing mechanism.

[0015] Furthermore, the waterproof woven bag fixing mechanism includes a base plate, a bag-supporting tube, an annular platform, and a bag-locking assembly. Perforations are evenly distributed on the surface of the construction platform. A base plate is laid on the construction platform, and bag-supporting tubes corresponding to the perforations are set on the base plate. Each bag-supporting tube is inserted into a perforation. An annular platform is provided at the upper outer edge of the bag-supporting tube, and a bag-locking assembly fitted onto the bag-supporting tube is provided at the upper end of the annular platform.

[0016] Furthermore, the locking bag assembly includes a locking band, a locking screw, a locking nut, and a connecting post. The locking band is rolled into a circular structure, and both ends of the locking band are bent outward vertically to form connecting ears. Connecting holes are provided on the connecting ears, and the locking screw is inserted into the connecting holes. The locking force of the locking band is adjusted by the locking nut. A connecting post is provided on the locking band at one end opposite to the connecting ears, and the connecting post is fixed to the base plate.

[0017] Furthermore, the mobile grouting mechanism includes an electric linear slide, a grouting plate, a cylinder, and grouting holes. Electric linear slides driven by servo motors are provided at both ends of the base plate along its length direction in the width direction. A cylinder is slidably mounted on the electric linear slide via a slider. A grouting plate is driven and mounted on the cylinder rod. A grouting hole is provided on the grouting plate at the position corresponding to the support tube.

[0018] Furthermore, the mobile grouting mechanism also includes support rods, with support rods evenly distributed circumferentially on the bottom surface of each grouting hole, and the outer diameter of the support ring formed by each support rod is smaller than the inner diameter of the support tube.

[0019] A method for fabricating a general-purpose building buffer structure component includes the following steps:

[0020] (1) Pretreatment of waterproof woven bags: Select any end of the waterproof woven bag, flatten the bag opening at the end, fold the flattened bag opening upward twice, then fold it downward twice, and finally sew two sealing lines horizontally to seal the end, so that a maze structure is formed inside the end.

[0021] (2) Bag installation: Insert one sealed end of the waterproof woven bag into the support tube and let it hang down naturally at the bottom of the construction platform. Fold the other end of the bag outward and put it on the opening of the support tube. The workers use the bag locking assembly to fix the waterproof woven bag on the support tube. In this way, the installation of all the waterproof woven bags on the support tube is completed.

[0022] (3) Grouting operation: Connect the grouting hole to the grouting machine through the grouting pipe, start the cylinder, the cylinder drives the grouting plate to descend, so that the support rod is inserted into the waterproof woven bag and the waterproof woven bag is opened; start the grouting machine, the grouting machine performs grouting operation on each waterproof woven bag according to the preset parameters. After a row of waterproof woven bags is grouted, the cylinder drives the grouting plate to rise, and the grouting plate automatically moves to the next station to perform grouting operation.

[0023] (3) Material feeding: After the grouting is completed and solidified, the staff loosens the locking bolts on the lock bag assembly, removes the grouting waterproof woven bag, and then seals the other unsealed end of it. The sealing method is the same as in step (1), thus obtaining the general building buffer structure component.

[0024] The advantages and positive effects of this invention are as follows:

[0025] 1. This invention has a simple structure, is easy to process and manufacture, has low raw material costs, requires no parts for assembly, and has low transportation costs, further reducing material expenditures and significantly alleviating the cost of tunnel engineering. The comprehensive mechanical properties of this invention are superior to traditional rigid pipes. Its yield strength is 12.97kN, basically the same as PVC rigid pipe (12.96kN), and close to PE rigid pipe (12.96kN); the maximum strength reaches 17.73kN, not only higher than PVC rigid pipe (16.36kN), but also exceeding MPP rigid pipe (17.49kN). Its yield strength corresponds to a strain of 2.1%, greater than traditional materials such as PVC rigid pipe (1.7%) and PE rigid pipe (1.5%), proving that it can achieve a "buffering-energy dissipation" effect through greater deformation when subjected to surrounding rock deformation, earthquakes, or impact loads. This ensures the safety of the main tunnel structure while avoiding local damage caused by excessive rigidity, perfectly balancing support strength and buffering characteristics.

[0026] 2. The general-purpose buffer structure components of this building adopt a composite structure of "foamed concrete core + waterproof woven bag". The waterproof woven bag is further composed of nylon cloth and waterproof material, which are bonded together to form a tight whole, greatly improving the structural stability. The waterproof material plays a waterproof role, preventing water seepage during the grouting process. The waterproof woven bag has good compatibility with foamed concrete, with no chemical reaction between the materials, and can adapt to the complex environment of the tunnel, which is humid and has many corrosive media. The reinforcement enhances the tensile strength of the components, which can resist the expansion force during the grouting of foamed concrete and the lateral compression of the tunnel surrounding rock, preventing pipe cracking and making it less prone to aging or damage during long-term use.

[0027] 3. The "labyrinth seal technology" adopted during the sealing process of the general building buffer structure components significantly improves the sealing performance compared to traditional sealing methods (such as simple bundling or heat melting). This structure forms multiple physical barriers at the end of the components, effectively preventing leakage during the pouring and consolidation of foamed concrete, ensuring that the foamed concrete fills the entire interior of the waterproof woven bag, and avoiding local voids or defects. At the same time, the sealing line and the folding structure work together, maintaining the tightness of the sealed area even during the expansion or contraction of the foamed concrete after curing, reducing rework caused by seal failure, and improving the qualified rate of finished products.

[0028] 4. The processing device配套 to this invention achieves automation and precision during the pouring process through modular design. The annular platform can expand the waterproof woven bag for convenient filling; the electric linear slide table enables the pouring plate to move along the construction platform, realizing continuous pouring of multiple rows of waterproof woven bags and reducing equipment adjustment time; the cylinder can flexibly adjust the height of the pouring plate to ensure accurate docking of the pouring hole and the bag-supporting tube, avoiding material splashing; after the bag-supporting rod is inserted into the interior of the waterproof woven bag, it can further expand the waterproof woven bag and guide the flow of foamed concrete, reducing the problem of uneven pouring; the bag-locking component can fix the waterproof woven bag to prevent it from falling off due to vibration or gravity during pouring. The overall device improves the pouring efficiency per batch and stabilizes the pouring quality, reducing manual operation errors.

[0029] 5. The components of this invention can be widely applied to the secondary lining of tunnels with different geological conditions. In soft rock tunnels, its large strain capacity can adapt to the continuous deformation of the surrounding rock; in tunnels in earthquake-prone areas, its excellent energy dissipation characteristics can reduce the impact of seismic loads on the main structure; in tunnel sections where rockfalls or vehicle impacts may occur, the multi-layer buffer structure can absorb impact energy and protect the tunnel safety. In addition, its low-cost advantage enables small and medium-sized tunnel projects to afford the construction of the buffer secondary lining and improve the overall safety of the tunnel structure.

Detailed Implementation

[0053] The present invention will be further described below with reference to the embodiments. The following embodiments are descriptive and not limiting, and should not be used to limit the scope of protection of the present invention.

[0054] The various experimental operations involved in the specific embodiments are all conventional techniques in the field. For parts not specifically annotated in this document, those skilled in the art can refer to various commonly used reference books, scientific and technological documents or related instructions and manuals prior to the filing date of this invention to carry out the operations.

[0055] Example 1: Buffer component for secondary lining of tunnel (underground engineering scenario)

[0056] In tunnel engineering, the buffer structure component of this invention is used as the core component of the secondary lining, replacing the traditional rigid PVC secondary lining pipe. During construction, the processed buffer component is stacked inside the initial support of the tunnel to form a continuous buffer lining layer.

[0057] In this application scenario, the composite structure of the foamed concrete core and the waterproof woven bag in the component can play multiple roles: the lightweight properties of the foamed concrete reduce the overall self-weight of the tunnel support; the PE waterproof layer of the waterproof woven bag can isolate water seepage from the surrounding rock of the tunnel, preventing the concrete core from softening; the reinforcing rib structure of the nylon bag enhances the tensile and compressive strength of the component, effectively resisting the lateral pressure generated by the convergence of the surrounding rock and the expansion force during the grouting process; the yield strength (12.97kN) is basically the same as that of traditional PVC rigid pipes, and the maximum strength (17.73kN) is better than that of traditional rigid pipes. Moreover, the 2.1% yield strain can absorb dynamic loads such as earthquakes and rockfall impacts through deformation, realizing buffering and energy dissipation functions, protecting the safety of the main tunnel structure, while the low cost advantage significantly reduces the material and transportation expenses of tunnel engineering. The specific technical solution is as follows:

[0058] A general-purpose building buffer structure component, such as Figure 7 and Figure 8 As shown, the device includes a waterproof woven bag 12-2 and a foamed concrete core 12-1 poured and molded inside the waterproof woven bag 12-2. The waterproof woven bag 12-2 includes a nylon bag 12-3 and a waterproof material 12-4 disposed on the outside of the nylon bag. The foamed concrete core is a buffer structure formed by pouring mixed foamed concrete into the waterproof woven bag. The filling density of the foamed concrete inside the waterproof woven bag is 500 kg / m³. 3 500kg / m 3 The high filling density results in a component with a significantly lower self-weight than traditional rigid pipes (PVC / PE / MPP), drastically reducing construction loads and transportation costs in scenarios such as tunnels and high-rise buildings. It is suitable for lightweight support requirements in soft rock tunnels and high-rise buildings on soft soil foundations. Furthermore, at this density, the foamed concrete adheres optimally to the waterproof woven bag after pouring, fully utilizing the reinforcing structure of the nylon bag to form a composite load-bearing system. This avoids the woven bag from expanding and bursting during pouring due to excessive density, or internal voids and load-bearing capacity failure due to excessively low density. At the same time, this density minimizes the amount of foamed concrete used while ensuring performance. Combined with the low-cost characteristics of the waterproof woven bag, the overall cost of the component is reduced by more than 90% compared to traditional rigid pipes, solving the industry problem of "high performance equals high cost" for traditional buffer components.

[0059] The aforementioned buffer structure component possesses both support strength for the building foundation and buffer strain characteristics. The yield strength of this buffer structure component is 12.97kN-17.73kN, and the corresponding strain is 1.3%-2.1%. This strain is significantly higher than that of traditional rigid pipes (PVC 1.7%, PE 1.5%, MPP 1.7%), allowing the component to absorb energy through greater elastic deformation before reaching its yield strength. This achieves the core function of "buffering and energy dissipation," avoiding the problem of traditional rigid pipes directly entering the rigid failure stage due to insufficient strain, and the load being directly transferred to the main building structure. Simultaneously, the strain upper limit of 2.1% is not excessively increased, preventing excessive deformation of the component under conventional loads and ensuring the stability of the building structure.

[0060] Preferably, the nylon bag 12-3 is woven from nylon yarn, and crisscrossing reinforcing lines are also woven into the nylon bag, forming reinforcing ribs. The strength of the nylon bag is 60-80KN. This strength can prevent the bag from rupturing during injection, and also prevent excessive strength from increasing rigidity and reducing deformation capacity, thus matching the buffering requirement of the component's 2.1% high strain, achieving a balance between strong load-bearing capacity and deformability. The deformation degree is 15%, which gives the nylon bag sufficient flexible deformation capacity to match the deformation characteristics of foamed concrete. The component achieves a yield strain of 2.1%, ensuring sufficient energy absorption through the coordinated deformation of the bag body and inner core under earthquake and impact loads. With a permeability of 2%-3%, this permeability effectively prevents cement slurry from seeping out from the gaps in the nylon bag during the pouring and consolidation of foamed concrete, ensuring the stability of the foamed concrete mix ratio and avoiding strength reduction and internal defects caused by slurry loss. It forms a double waterproof guarantee with the outer PE waterproof material. The low permeability of the nylon bag, combined with the fully sealed waterproof of the PE layer, enables the waterproof performance of the component to reach the level of traditional rigid pipes, while retaining the flexibility of woven bags.

[0061] Preferably, the waterproof material 12-4 is PE material, which is thermally bonded to the outer surface of the nylon bag. This prevents water seepage from the tunnel into the concrete inside the pipe, thus preventing the pipe material from softening.

[0062] A processing device for processing a general-purpose building buffer structure component as described above, such as... Figures 1 to 6 As shown, it includes a construction platform 1, a waterproof woven bag fixing mechanism and a mobile grouting mechanism. The construction platform is erected on the ground by columns. The waterproof woven bag fixing mechanism is laid on the platform. The mobile grouting mechanism is movably installed on the upper end of the waterproof woven bag fixing mechanism.

[0063] like Figure 1As shown, a waterproof woven bag fixing mechanism is installed on the construction platform 1. The waterproof woven bag fixing mechanism can hold the opened waterproof woven bag 12-2. The movable grouting mechanism can pour foamed concrete into the opened waterproof woven bag 12-2. The construction platform 1 is surrounded by columns, which can raise and support the construction platform 1 as a whole. A staircase is set on one side of the construction platform 1 to facilitate workers to go up and down the construction platform 1. A railing is set on the top of the construction platform 1 to prevent workers from falling.

[0064] like Figures 1 to 2 As shown, the waterproof woven bag fixing mechanism includes a base plate 2, bag-supporting tubes 3, annular platform 4, and a bag-locking assembly 14. Perforations are evenly distributed on the surface of the construction platform 1. The base plate 2 is laid on the construction platform 1, and bag-supporting tubes 3 corresponding to the perforations are installed on the base plate 2. Each bag-supporting tube 3 passes through a perforation. An annular platform 4 is provided at the upper outer edge of the bag-supporting tube 3, and a bag-locking assembly fitted onto the bag-supporting tube 3 is located at the upper end of the annular platform 4. This facilitates the subsequent pouring of foamed concrete into the waterproof woven bag 12-2.

[0065] like Figures 5 to 6 The locking bag assembly 14 includes a locking band, a locking screw, a locking nut, and a connecting post 15. The locking band is rolled into a circular structure, and both ends of the locking band are bent outwards vertically to form connecting ears. Connecting holes are provided on the connecting ears, and the locking screw passes through the connecting holes. The locking force of the locking band is adjusted by the locking nut. A connecting post 15 is provided on the locking band at the end opposite to the connecting ears, and the connecting post 15 is fixed to the base plate 2. The locking bag assembly 14 can securely lock the waterproof woven bag 12-2 fitted on the annular platform 4, preventing it from falling off and ensuring the stability of the pouring process.

[0066] like Figures 3 to 4 As shown, in this embodiment, the mobile grouting mechanism includes an electric linear slide 5, a grouting plate 10, a cylinder 8, and grouting holes 11. Electric linear slides 5, driven by servo motors, are arranged at both ends of the base plate 2 along its length. Cylinders 8 are slidably mounted on the electric linear slides 5 via sliders. The grouting plate 10 is driven and mounted on the cylinder rod of the cylinder 8. Grouting holes 11 are provided on the grouting plate 10 corresponding to the positions of the bag-supporting tubes 3. Workers can adjust the position of the grouting plate 10 by manipulating the electric linear slide 5 to align and grout each row of waterproof woven bags. Simultaneously, workers can adjust the vertical position of the grouting plate 10 by manipulating the cylinder 8 to ensure the stability of the grouting process, prevent concrete accumulation that could cause pipe blockage, and ensure the fluidity of the concrete grouting through dynamic distance adjustment, avoiding uneven and insufficient grouting within the pipe. The grouting platform can also be controlled by an external electrical control system to achieve automated grouting and reduce workload.

[0067] In this embodiment, the mobile grouting mechanism further includes support rods 13. Support rods are evenly distributed circumferentially on the bottom surface of each grouting hole 11, and the outer diameter of the support ring formed by the support rods is smaller than the inner diameter of the support tube 3. The bottom end of the support rod 13 is semi-elliptic or hemispherical. The support rod 13 can enter the waterproof woven bag 12-2 as the grouting plate 10 falls, and fit against the inner wall of the waterproof woven bag 12-2, while simultaneously opening the waterproof woven bag 12-2 to facilitate subsequent grouting of foamed concrete and reduce the problem of insufficient or uneven grouting. The bottom end of the support rod is set to a semi-elliptic or hemispherical shape to prevent damage to the inner wall of the waterproof woven bag 12-2.

[0068] The accompanying processing device of this invention achieves automation and precision in the grouting process through modular design, enabling continuous grouting of multiple support tubes 3 and reducing equipment adjustment time. After the support rod is inserted into the tube, it further expands the tube and guides the flow of foamed concrete, reducing uneven grouting. The locking assembly secures the tube, preventing it from falling off due to vibration or pressure during grouting. The overall device improves the efficiency of single-batch grouting and ensures stable grouting quality, reducing human error.

[0069] The processing method for a general-purpose building buffer structure component as described above includes the following steps:

[0070] (1) Pretreatment of waterproof woven bags: Select any end of the waterproof woven bag 12-2, flatten the bag opening at that end, fold the flattened bag opening upwards twice, then fold it downwards twice, and finally sew two sealing lines 12-5 horizontally to seal the end, so that a maze structure is formed inside the end, such as Figure 9 and Figure 10 As shown;

[0071] (2) Bag installation: Insert one sealed end of the waterproof woven bag 12-2 into the support tube 3 and let it hang down naturally at the lower end of the construction platform 1. Fold the other end of the bag outward and put it on the opening of the support tube 3. The workers use the bag locking assembly to fix the waterproof woven bag 12-2 on the support tube 3. In this way, the installation of all the waterproof woven bags 12-2 on the support tube 3 is completed.

[0072] (3) Grouting operation: Connect the grouting hole to the grouting machine through the grouting pipe, start the cylinder 8, the cylinder 8 drives the grouting plate to descend, so that the support rod is inserted into the waterproof woven bag 12-2 and the waterproof woven bag 12-2 is opened; start the grouting machine, the grouting machine performs grouting operation on each waterproof woven bag 12-2 according to the preset parameters. After the grouting of one row of waterproof woven bags 12-2 is completed, the cylinder 8 drives the grouting plate to rise, and the grouting plate 10 automatically moves to the next station to perform grouting operation;

[0073] (3) Material feeding: After the injection is completed and solidified, the staff loosens the locking bolts on the lock bag assembly, removes the injected waterproof woven bag 12-2, and then seals the other unsealed end. The sealing method is the same as in step (1), thus obtaining the general building buffer structure component 12.

[0074] This method is easy to operate, requiring no complex equipment or high-precision operation, and can be mastered by ordinary construction personnel after simple training. The folding and sewing operations in the sealing process can be completed manually or with semi-automatic equipment, adapting to the temporary processing needs of tunnel construction sites, or can be mass-produced in the factory and transported to the site. Compared with traditional sealing methods (such as simple binding or heat fusion), this sealing method significantly improves sealing performance. This structure creates multiple physical barriers at the pipe ends, effectively preventing leakage during the pouring and solidification of foamed concrete, ensuring that the foamed concrete fills the entire interior of the pipe, and avoiding local voids or defects. Simultaneously, the sealing line and folding structure work together to maintain the tightness of the seal even during the expansion or contraction of the solidified foamed concrete, reducing rework due to seal failure and improving the finished product qualification rate.

[0075] The universal building buffer structure component of the present invention is compared with commercially available pipe materials.

[0076] A market cost survey was conducted on rigid pipes and flexible pipes available on the market, and the results are shown in Table 1 below.

[0077] Table 1. Price list of rigid pipes and flexible pipes and different materials from various manufacturers.

[0078]

[0079] As shown in Table 1, the price of PE rigid pipe is 10.9-11.9 yuan / meter, the price of end caps is 2.9-5 yuan / meter, and the total price is 16.7-21.9 yuan / meter; the price of PVC rigid pipe is 9.4-15.07 yuan / meter, the price of PP rigid pipe is 12-13.5 yuan / meter, the price of ABS rigid pipe is 35 yuan / meter, the price of PE soft water pipe is 4.41 yuan / meter, the price of PE composite water pipe is 2.44 yuan / meter, the price of PVC steel wire flexible hose is 41 yuan / meter, and the price of polyester woven bag is 1.2 yuan / meter. The price of the nylon cloth of this invention is 1.1 yuan / meter, and the price of the waterproof material is 0.05 yuan / meter. Therefore, compared with the aforementioned materials, the manufacturing cost of the product of this invention is significantly reduced. Adding transportation costs, the overall cost can be reduced by more than 90%.

[0080] Using rigid PE pipes, rigid PVC pipes, rigid MPP pipes, polyester sewn bags, PE soft bags, and PE woven bags, and filling them with foamed concrete, the resulting pipes are as follows: Figure 11As shown. Strength comparison tests were conducted on the pipes obtained after grouting, and the test methods were in accordance with the "Technical Specification for Design and Construction of Buffer Layer of Support Structure for Underground Engineering".

[0081] like Figure 12 As shown in the figure, strength tests were conducted on different batches of rigid PE pipes. The results are shown in the figure. The yield strength of the rigid PE pipe after being filled with foamed concrete was 9.64 kN, the maximum strength was 14.81 kN, the strain at the yield strength value was 1.5%, and there was no rebound after the yield strength.

[0082] like Figure 13 As shown in the figure, strength tests were conducted on different batches of rigid PVC pipes. The results are shown in the figure. The yield strength of the rigid PVC pipes after being filled with foamed concrete was 12.96 kN, the maximum strength was 16.36 kN, the strain at the yield strength value was 1.7%, and there was no rebound after the yield strength.

[0083] like Figure 14 As shown in the figure, strength tests were conducted on different batches of MPP rigid pipes. The results are shown in the figure. The yield strength of the MPP rigid pipe after being filled with foamed concrete was 11.91 kN, the maximum strength was 17.49 kN, the strain at the yield strength value was 1.7%, and there was no rebound after the yield strength.

[0084] like Figure 15 As shown in the figure, strength tests were conducted on different batches of polyester sewn bags. The results are shown in the figure. The yield strength of the pipe material obtained by injecting foamed concrete into the polyester hose is 16.68kN, the maximum strength is 17.56kN, the strain at the yield strength value is 1.3%, and there is no rebound after the yield strength.

[0085] like Figure 16 As shown in the figure, strength tests were conducted on different batches of PE soft bags. The results are shown in the figure. The yield strength of the pipe obtained after the PE hose was filled with foamed concrete was 10.05kN, the maximum strength was 10.96kN, the strain at the yield strength value was 1.3%, and there was no rebound after the yield strength.

[0086] like Figure 17 As shown, for different batches of P E The woven bag (in this invention) was subjected to a strength test, and the results are shown in the figure. The yield strength of the pipe obtained after the PE woven bag was filled with foamed concrete was 12.97kN, the maximum strength was 17.73kN, the strain at the yield strength value was 2.1%, and there was no rebound after the yield strength.

[0087] Then, a comprehensive compression test was conducted on the above six materials using rigid and flexible foamed concrete, and the results are as follows: Figures 18 to 20 As shown. PE- is the secondary lining pipe material of this invention.

[0088] Therefore, the yield strength of the PE woven bag foam concrete of this invention is 12.97 kN, which is almost the same as that of traditional PVC rigid pipe (12.96 kN), slightly higher than that of PE rigid pipe (9.64 kN), and close to that of MPP rigid pipe (11.91 kN). This result shows that the load-bearing capacity of PE woven bags from the initial yield stage to the initial yield stage is fully comparable to that of traditional rigid pipes, meeting the requirements of "foundation support strength" for tunnel secondary lining and ensuring that premature yield failure does not occur under normal surrounding rock pressure. The maximum strength of the PE woven bag foam concrete of this invention reaches 17.73 kN, which is not only higher than that of PVC rigid pipe (16.36 kN) and PE rigid pipe (14.81 kN), but also exceeds that of MPP rigid pipe (17.49 kN). This indicates that under extreme loads, the resistance to damage of PE woven bags is superior to that of most traditional rigid pipes, providing higher safety redundancy for tunnel structures and reducing the risk of structural damage due to excessive loads. The PE woven bag foam concrete of this invention exhibits a strain of 2.1% at yield strength, significantly higher than that of PVC rigid pipes (1.7%), PE rigid pipes (1.5%), and MPP rigid pipes (1.7%), and only slightly lower than that of PE soft bags (1.3%) and polyester sewn bags (1.3%). This indicates that PE woven bags can absorb energy through greater deformation before reaching yield strength, resulting in a more thorough "buffering-energy dissipation" process. In contrast, traditional rigid pipes (such as PVC and PE rigid pipes) have smaller strains and are prone to direct rigid failure under load, making it difficult to provide a buffering effect. This suggests that PE woven pipes are better suited to the "flexible support" requirements in tunnel engineering, especially in scenarios such as earthquakes and large deformations of surrounding rock, effectively reducing the impact of loads on the main structure.

[0089] In summary, the general-purpose building buffer structure component of this invention has similar yield strengths to PVC and PE rigid pipes, which are 13.04, 12.96, and 12.97, respectively. From the perspective of yield strength and strain, PE braided hose has similar performance to PE rigid pipe, but its price is much lower than that of PE rigid pipe. It has good performance and low cost. Its yield strength corresponds to a strain of 2.1%, which is greater than that of traditional materials such as PVC rigid pipe (1.7%) and PE rigid pipe (1.5%). This indicates that when subjected to surrounding rock deformation, earthquake or impact loads, it can achieve buffering and energy dissipation through greater deformation, which not only ensures the safety of the main tunnel structure, but also avoids local damage caused by excessive rigidity, thus taking into account both support strength and buffering characteristics.

[0090] Example 2: Buffer connection between floor slab and wall in high-rise buildings (seismic scenario for high-rise buildings)

[0091] In the construction of high-rise buildings, especially in earthquake-prone areas or areas with soft soil foundations, the buffer structure component of this invention is used as a buffer connector at the junction of the floor slab and the load-bearing wall. According to the building structural design requirements, the length of the component (500-1000mm) and the density of the foamed concrete are adjusted. After processing and molding, a groove is pre-reserved at the top of the wall. The buffer component is horizontally embedded into the groove, and then the floor slab concrete is poured, forming a firm connection between the component and the floor slab and wall.

[0092] In this application scenario, the advantages of the components fully meet the seismic requirements of high-rise buildings: First, the waterproof woven bags have good compatibility with concrete, with no interface peeling issues, and can adapt to the humid environment inside the building for a long time; Second, the high strain capacity of 2.1% can absorb the relative deformation stress between the floor slab and the wall under seismic loads, preventing the wall from cracking due to rigid collisions; Third, the modular processing method allows for the mass production of components of different sizes to adapt to different building designs with different floor heights and apartment layouts, and the raw material cost is only less than 1 / 10 of that of traditional metal buffer connectors, significantly reducing the cost of seismic engineering for high-rise buildings; Fourth, the labyrinth-style sealing process ensures the sealing of the component ends, preventing grout leakage during concrete pouring, ensuring the component is fully filled, and improving the stability of seismic buffering.

Therefore, the scope of the invention is not limited to the contents disclosed in the embodiments.
