Abstract
Description
Technical Field
[0001] This invention relates to the field of dynamic compaction construction technology in building engineering, and in particular to a flexible vibration isolation airbag, an injection-type airbag inserter, and their construction process. Background Technology
[0002] Dynamic compaction is a common foundation treatment method in construction engineering. It uses repeated hammering to compact the soil, increasing its bearing capacity. However, the compaction process generates strong vibration waves that propagate to the surrounding soil, potentially causing disturbance, cracking, or even structural damage to the protected area near the construction site. To mitigate the transmission of vibration waves from dynamic compaction, current construction methods commonly employ trench isolation. This involves excavating a vibration isolation trench between the dynamic compaction area and the protected area, using the trench's hollow structure to block the propagation path of the vibration waves, thus achieving vibration isolation and protection.
[0003] Although the existing trenching vibration isolation technology is simple to operate and low in cost, certain problems have been found in actual construction and use. For example, the structure of this type of vibration isolation trench is not stable. The vibration generated by dynamic compaction construction can easily cause local collapse and landslide of the side wall soil of the vibration isolation trench. The collapse phenomenon is more serious in soil layers with poor stability such as soft soil and sandy soil. The collapsed soil fills the cavity of the vibration isolation trench, which greatly weakens the vibration isolation effect.
[0004] For some construction scenarios with high requirements for vibration isolation, rigid vibration isolation structures such as cement-soil mixing piles are also used. Although this improves the stability of the vibration isolation structure, the construction process of this type of structure is complex, the equipment investment is large, the construction period is long, and the vibration isolation effect of the rigid structure is greatly affected by the gaps in the pile connection. In addition, the rigid structure is difficult to recycle after construction, resulting in material waste and significantly increasing construction costs.
[0005] In summary, existing vibration isolation methods for dynamic compaction construction all suffer from contradictions between structural stability, vibration isolation effect, construction efficiency, and construction cost, making it difficult to simultaneously achieve effective vibration isolation and protection while maintaining construction economy and convenience. Therefore, it is necessary to develop a flexible vibration isolation airbag with high structural stability, good vibration isolation effect, convenient construction, and reusability, as well as equipment capable of continuous plate insertion for this flexible vibration isolation airbag, to replace traditional trenching and rigid vibration isolation methods. Summary of the Invention
[0006] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention proposes a flexible vibration-damping airbag, an injectable airbag insertion plate machine, and its construction process.

[0010] Preferably, the bottom of the vibration isolation airbag body is provided with at least one set of connecting ear holes.
[0011] This invention also proposes an intubation airbag inserter, comprising: The traveling equipment is equipped with a vertical truss and a control room for overall machine control, which are fixed on top. The feeding roller is rotatably connected to the top of the traveling equipment, and has several of the above-mentioned flexible vibration isolation airbags wound together end to end inside. The insert plate has an internal cavity, and a high-frequency vibrating hammer is fixedly connected to the top of the insert plate. The high-frequency vibrating hammer is slidably mounted on the side of the truss through a braking assembly and can move vertically along the extension direction of the truss. A through hole communicating with the cavity is opened at the center of the high-frequency vibrating hammer, and a limiting groove for accommodating the limiting inflatable airbag is opened above the through hole. A guiding and conveying assembly, located above the truss, is used to convey the flexible vibration isolation airbag in the feeding roller to the top of the through hole, and guide it through the through hole into the receiving cavity of the insert plate. The bottom end of the flexible vibration isolation airbag passes through the receiving cavity and is detachably connected to a pile tip. Both the first and second telescopic rods are located on the outside of the insert plate. The output end of the first telescopic rod is connected to a peeling plate, which is driven to abut against the protective strip between the two adjacent flexible vibration isolation airbags inside and above the insert plate. The upper and lower flexible vibration isolation airbags are peeled off by the downward force of the insert plate. The output end of the second telescopic rod is connected to a stop rod, which is driven to insert into the second inflation / deflation port of the limiting inflation airbag, so that the limiting inflation airbag inflates and falls into the limiting groove, forming a vertical limit on the main body of the vibration isolation airbag inside the insert plate.
[0012] Preferably, the braking assembly includes a guide rod disposed on the outside of the truss and a guide rail fixedly connected to the inside of the high-frequency vibratory hammer, the guide rail being slidably disposed along the guide rod; it also includes a winch disposed on the traveling equipment, the other end of the traction cable in the winch being connected to the high-frequency vibratory hammer through a guide wheel unit disposed on the truss.
[0013] Preferably, the guiding and conveying assembly includes a top frame fixed above the truss, on which two main conveying rollers are arranged adjacent to each other, and the two main conveying rollers convey the flexible vibration isolation airbag between them through a drive motor; the top frame is also provided with an inclined conveying roller for supporting the flexible vibration isolation airbag.
[0014] Preferably, the guiding and conveying assembly further includes a sliding frame that is slidably disposed along the top frame, and the guide rod is fixed below the sliding frame; the sliding frame has a cavity, and an auxiliary conveying roller is disposed in the cavity, and the flexible vibration isolation airbag falls into the insert plate after being lifted by the auxiliary conveying roller.
[0015] Preferably, an insert shell is fixed above the pile tip, and the insert shell has at least one set of limiting holes; when the bottom end of the flexible vibration isolation airbag is placed inside the insert shell, a bolt is used to pass through the limiting holes and the connecting ear hole and is threaded with a nut to connect the pile tip to the flexible vibration isolation airbag.
[0016] This invention also proposes a construction process for an intubation airbag plate insertion machine, which uses any of the above-mentioned intubation airbag plate insertion machines and includes the following steps: S1. Based on the design drawings, measure and lay out the lines at the construction site to determine the insertion position of the flexible vibration isolation airbags; S2, after deflating several flexible vibration isolation airbags, connect them end to end and wind them into the feeding roller; install the feeding roller onto the traveling equipment, drive the traveling equipment to move to the area to be constructed, so that the insert plate is perpendicular to the area to be inserted, and complete the equipment positioning; S3, the first set of flexible vibration isolation airbags is pulled through the main conveyor roller, and after the attitude is adjusted by the inclined conveyor roller and the auxiliary conveyor roller, it is aligned with the entrance of the insert plate receiving cavity; the drive motor is started, and the airbags are lowered into the insert plate through the main conveyor roller until the limit inflated airbags are close to the limit groove, and the conveying is stopped. S4, activate the second telescopic rod, causing the stop rod to insert into the second inflation / deflation port and open the valve core. The limiting expansion airbag expands under the action of the spring, and then the second telescopic rod retracts, closing the valve core. Activate the first telescopic rod, causing the peeling plate to abut against the protective strip between the airbag inside the insert plate and the adjacent airbag above. Lower the insert plate through the winch, and the insert plate drives the internal airbag to move down synchronously. With the help of the peeling plate, the protective strip is separated from the upper airbag, allowing the expanded limiting expansion airbag to fall into the limiting groove, thus achieving vertical limiting of the vibration isolation airbag body. S5, when the bottom of the insert plate moves to above the soil surface of the area to be inserted, fix the pile tip to the bottom of the airbag; continue to lower the insert plate, and when the pile tip is close to the soil, start the high-frequency vibratory hammer to drive the insert plate to vibrate and move down, so that the pile tip is inserted to the designed depth below the soil surface of the area to be inserted; after the high-frequency vibratory hammer is placed at a set distance above the soil surface, stop vibrating. S6, insert the push rod into the second inflation / deflation port, squeeze the limiting expansion airbag to contract and expel the air, remove the push rod and close the valve core; use a winch to lift the insert plate to the initial high position; S7, drive the traveling equipment to the next insertion area, start the main conveyor roller to convey the subsequent flexible vibration isolation airbags, repeat steps S4 to S6 to complete the insertion of all flexible vibration isolation airbags; After the flexible vibration isolation airbags are installed, mark the compaction points and carry out dynamic compaction. After the dynamic compaction is completed, backfill the vertical grooves formed to restore the site to flatness.
[0017] Compared with existing technologies, the above technical solution has the following advantages or beneficial effects: 1. This invention proposes a flexible vibration isolation airbag. This airbag is inserted between two areas to form a continuous barrier, which can significantly shorten the construction cycle and reduce construction costs, while solving problems such as easy collapse and filling failure in traditional vibration isolation trenches. Furthermore, due to its flexible characteristics, it can be rolled up entirely into a feeding roller, greatly improving the overall storage integrity and portability during transportation.
[0018] 2. In this invention, the protective belt of the flexible vibration isolation airbag enables a detachable connection between the ends of adjacent airbags, allowing the airbags to be rolled up and placed on the feeding roller of the inserter, thus meeting the continuous conveying and insertion requirements of the inserter. At the same time, after the flexible vibration isolation airbag is inserted, the free end of the protective belt can be folded over and glued to the upper part of the airbag body to form a closed protective barrier around the limiting expansion airbag and the inflation / deflation port.
[0019] 3. The airbag inserting machine proposed in this invention integrates multiple functions such as material feeding, conveying, positioning, insertion, and resetting. During continuous construction, the inserting machine drives the peeling plate to abut against the protective belt joint of the adjacent airbag through the first telescopic rod. With the help of the downward force of the inserting plate, the adjacent flexible vibration isolation airbags are automatically peeled off. In conjunction with the second telescopic rod driving the abutment rod to insert and inflate, a single set of airbags is quickly positioned and limited, solving the problem of segmented insertion of continuously wound airbags.
[0020] 4. In this invention, the insert plate in the airbag inserting machine is provided with a receiving cavity to ensure that the airbag is vertically extended. It is matched with the limiting groove and the limiting expansion airbag after inflation to ensure that the flexible vibration isolation airbag will not fall out when it is driven in with the vibration of the insert plate. Moreover, the insert plate can be easily pulled out and recycled after the flexible vibration isolation airbag is put into the soil, leaving only the flexible vibration isolation airbag to form a vibration isolation barrier.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0039] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0040] like Figures 1 to 4 As shown in the figure, this embodiment proposes a flexible vibration isolation airbag a. This airbag is mainly used in the field of dynamic compaction construction in building engineering. It is inserted between the dynamic compaction construction area and the protected area where no construction is required. The flexible vibration isolation characteristics of the airbag weaken the transmission of vibration waves generated by dynamic compaction construction, and avoid construction vibration causing disturbance and damage to surrounding buildings, pipelines and the soil in the protected area. Preferably, the flexible vibration isolation airbag a is integrally molded from EPDM rubber and reinforced with polyester fiber as an internal reinforcing layer. This material has excellent anti-aging, UV resistance and high and low temperature resistance properties, making it suitable for the open-air working conditions of dynamic compaction construction and preventing the airbag from aging rapidly due to sun and rain. At the same time, EPDM rubber has excellent elasticity and tear resistance, which can resist the repeated compression of dynamic compaction vibration and the friction and scraping of the soil, while ensuring the sealing performance of the airbag after inflation and preventing air leakage.
[0041] Specifically, the flexible vibration isolation airbag a includes a vibration isolation airbag body a1, which is a vertically extending columnar structure. Its overall size can be adjusted according to the vibration wave influence range, construction area and protection area of the dynamic compaction construction to adapt to the vibration isolation requirements of different construction scenarios. The upper side of the vibration isolation airbag body a1 is integrally connected to a first inflation / deflation port a2, which is equipped with a sealing cap. Operators can fill the vibration isolation airbag body a1 with gas through the first inflation / deflation port a2 and adjust the expansion degree of the vibration isolation airbag body a1 according to the vibration isolation requirements. Gas can also be discharged through this port, which facilitates the storage and transportation of the airbag.
[0042] A limiting expansion airbag a3 is fixedly connected to the top of the vibration isolation airbag body a1. The limiting expansion airbag a3 adopts a corrugated columnar structure. This structural design can improve its structural stability after inflation and avoid deformation under the pressure of external construction forces. The side of the limiting expansion airbag a3 is connected to a second inflation / deflation port a4. After inflation, the radial dimension of the limiting expansion airbag a3 is larger than that of the vibration isolation airbag body a1, forming a T-shaped three-dimensional structure with the vibration isolation airbag body a1. This T-shaped structure design can limit the top of the vibration isolation airbag body a1 inserted into the insertion plate 4, preventing the vibration isolation airbag body a1 from sliding down and falling out of the insertion plate 4 during the insertion process, ensuring that the vibration isolation airbag body a1 always maintains a vertically extended working state, and ensuring the stability of the vibration isolation effect after being inserted into the soil.
[0043] A protective belt a5 is connected to the outer wall of the vibration isolation airbag body a1. One end of the protective belt a5 is a fixed end, which is fixedly connected to the upper side of the vibration isolation airbag body a1 by means of heat pressing or other methods. The other end of the protective belt a5 is a free end, which can be detachably connected to the side of the vibration isolation airbag body a1 away from the fixed end, or to the bottom side of the adjacent vibration isolation airbag body a1 above.
[0044] The design of the protective belt a5 has dual practical value. First, during the storage and transportation of the airbags, several flexible vibration isolation airbags a can be connected to each other through the protective belt a5, and then rolled up and placed into the discharge roller 3 as a whole, preventing the airbags from scattering or tangling, greatly improving the neatness of storage and the convenience of transportation. At the same time, the rolled placement of the discharge roller 3 also facilitates rapid unfolding and laying during construction. Second, after the flexible vibration isolation airbags a are inserted between the construction area and the protected area, the free end of the protective belt a5 can be wrapped around the limiting expansion airbag a3, the first inflation / deflation port a2, and the second inflation / deflation port a4 to form a protective barrier. This can, to a certain extent, prevent the impact of sand, gravel, and soil splashed during the dynamic compaction construction on the above-mentioned components, avoid damage to the inflation / deflation port, failure of the seal, or damage to the limiting expansion airbag a3, and extend the service life of the airbags.
[0045] refer to Figure 4 Furthermore, in order to adapt to the winding and storage requirements of the flexible vibration isolation airbag a and to achieve the rapid expansion of the limiting expansion airbag a3, a spring a9 is connected between the two side walls of the limiting expansion airbag a3 along its length direction. A valve core is fixedly installed in the second inflation / deflation port a4. The valve core is a one-way sealing structure and remains closed under normal conditions to effectively prevent gas leakage.
[0046] The limiting expansion airbag a3 is in a compressed state during initial storage and transportation. The spring a9 is compressed synchronously with the limiting expansion airbag a3. At this time, the overall volume of several flexible vibration isolation airbags a is greatly reduced, making it easier to wind onto the unloading roller 3 and saving storage and transportation space. When the flexible vibration isolation airbag a needs to be put into construction, the external abutment rod 12 is inserted into the valve core. The external force pushes open the sealing structure of the valve core, and the limiting expansion airbag a3 automatically expands outward under the elastic reset action of the spring a9, quickly drawing in external gas to complete the expansion. This causes the flexible vibration isolation airbag a to quickly form a T-shaped structure. Then, the abutment rod 12 is removed from the valve core, and the valve core automatically resets and closes. The limiting expansion airbag a3 can then maintain its expanded state, achieving the top limiting effect on the vibration isolation airbag body a1. The entire expansion operation does not require additional inflation equipment, which can greatly improve the efficiency of construction and laying.
[0047] Conversely, when the flexible vibration isolation airbag a needs to be recycled and stored after construction is completed, the push rod 12 is inserted into the valve core again to open the sealing structure. The two side walls of the limiting expansion airbag a3 are squeezed by external force, and the gas inside is completely emptied from the second inflation / deflation port a4. The spring a9 is compressed again along with the limiting expansion airbag a3. Then the push rod 12 is pulled out to restore the valve core to the closed state, so that the limiting expansion airbag a3 can be kept in the current compressed state, which is convenient for subsequent winding, storage and reuse.
[0048] In this embodiment, to facilitate the easy disassembly and connection of the free end of the protective belt a5, a hook and loop fastener surface a6 is fixedly connected to the outer surface of the end of the protective belt a5 away from the fixed end. The length of the hook and loop fastener surface a6 is adapted to the width of the protective belt a5. The outer side wall of the vibration isolation airbag body a1 away from the fixed end of the protective belt a5, and the outer side wall of the bottom side of the vibration isolation airbag body a1 corresponding to the fixed end of the protective belt a5, are both fixedly connected to a hook and loop fastener surface a7. The length of the hook and loop fastener surface a7 is 2-3 times that of the hook and loop fastener surface a6, leaving sufficient adhesive adjustment margin. The hook and loop fastener surface a6 and the hook and loop fastener surface a7 can be tightly fitted and bonded.
[0049] The Velcro connection method is simple to operate and requires no tools. During the storage and transportation stage, the operator can attach the Velcro side a6 of the free end of the protective tape a5 to the Velcro side a7 of the bottom side of the adjacent vibration isolation airbag body a1, quickly realizing the series connection of several flexible vibration isolation airbags a, which is convenient for winding onto the unloading roller 3. During the construction and use stage, the Velcro side a6 of the free end of the protective tape a5 can be attached to the Velcro side a7 of the vibration isolation airbag body a1 on the side away from the fixed end, so that the protective tape a5 forms a closed protective ring around the limiting expansion airbag a3, protecting the inflation and deflation port and the limiting expansion airbag a3. When disassembly is required, the Velcro can be directly torn off to separate them, making the operation convenient and efficient.
[0050] Furthermore, the bottom of the vibration isolation airbag body a1 is provided with at least one set of connecting ear holes a8. The connecting ear holes a8 are through-hole structures made of thickened rubber, and a metal protective ring is fixed on their outer ring. In actual dynamic compaction construction, the vibration isolation airbag body a1 can be connected to the pile tip 8 by means of the connecting ear holes a8, and the vibration isolation airbag body a1 can be pushed to the designated vibration isolation position by inserting the pile tip 8.
[0051] refer to Figures 5 to 14 This invention also proposes an infeed airbag inserting machine, which is mainly used in the field of dynamic compaction construction in building engineering. It is used in conjunction with the aforementioned flexible vibration isolation airbag a to achieve continuous and rapid insertion of the flexible vibration isolation airbag a between the dynamic compaction construction area and areas requiring no construction protection, thereby significantly improving construction efficiency and ensuring the stability of the vibration isolation effect. The inserting machine is based on the traveling device 1 and integrates multiple functions such as material feeding, conveying, positioning, insertion, and resetting. All components work together in a coordinated manner, adapting to complex outdoor dynamic compaction construction conditions. The entire machine uses high-strength steel for its main frame, combining structural stability with operational flexibility.
[0052] Specifically, the airbag insertion machine includes a traveling device 1, which uses a tracked chassis. A vertical truss 2 is fixedly installed on the top of the traveling device 1 by welding, which can withstand the vibration load of the high-frequency vibratory hammer 5 during operation. A control room for overall machine control is also fixedly installed on one side of the traveling device 1. The control room integrates an operating console, display screen, control buttons and various sensor display modules. Operators can complete all operations such as moving, conveying and inserting the machine in the control room, realizing remote control to improve construction safety.
[0053] On the upper right of the traveling device 1, on the right side of the vertical truss 2, a feeding roller 3 is rotatably connected. Several flexible vibration isolation airbags a are wound inside the feeding roller 3, and the flexible vibration isolation airbags a are connected end to end by a protective belt a5. The whole after winding is cylindrical, which is adapted to the structure of the feeding roller 3 to ensure the controllability of the conveying of the flexible vibration isolation airbags a.
[0054] A plate 4 and a high-frequency vibrating hammer 5 are fitted on the side of the vertical truss 2. The plate 4 is a hollow square tube structure with a through cavity running vertically inside. This ensures that the flexible vibration isolation airbag a remains fully extended after being inserted vertically, without bending or compression. The top of the plate 4 is connected to the bottom of the high-frequency vibrating hammer 5. The high-frequency vibrating hammer 5 is slidably mounted on the side of the truss 2 via a braking assembly and can move freely along the vertical extension direction of the truss 2, enabling the vertical lifting and lowering of the plate 4. A through hole 6 is provided at the center of the high-frequency vibrating hammer 5, which communicates with the cavity of the plate 4. The diameter of the through hole 6 is larger than the outer diameter of the flexible vibration isolation airbag a, ensuring that the airbag passes through smoothly. Above the through hole 6, a limiting groove 7 is provided to accommodate the limiting inflated airbag a3, providing support and accommodating space for the expansion of the limiting inflated airbag a3. At the same time, it can vertically limit the expansion of the limiting inflated airbag a3, preventing it from falling out of the plate 4.
[0055] The top of the vertical truss 2 is equipped with a guide conveying assembly. The core function of this assembly is to convey the flexible vibration isolation airbag a wound in the feeding roller 3 to the through hole 6 of the high-frequency vibrating hammer 5, and guide it into the receiving cavity of the insert plate 4 through the through hole 6, so as to ensure that the airbag remains vertically extended during the conveying process. After the bottom end of the flexible vibration isolation airbag a passes through the receiving cavity of the insert plate 4, it is detachably connected to the pile tip 8. The pile tip 8 has the ability to break the soil and can effectively transmit the vibration force of the high-frequency vibrating hammer 5 to the soil, driving the flexible vibration isolation airbag a to be driven down to the preset depth simultaneously.
[0056] A first telescopic rod 9 and a second telescopic rod 11 are fixedly installed on the outer wall of the insert plate 4, and a monitoring camera is installed in this area to achieve individual or linkage control in conjunction with the control room; the output end of the first telescopic rod 9 is set towards the receiving cavity of the insert plate 4, and a peeling plate 10 is fixedly connected to the output end. The peeling plate 10 has a wedge-shaped structure and can abut against the protective strip a5 between the two adjacent flexible vibration isolation airbags a inside the insert plate 4 and above it under the drive of the first telescopic rod 9. Then, with the downward force of the insert plate 4 moving down, the adhesive joint of the protective strip a5 of the upper and lower flexible vibration isolation airbags a is peeled off, realizing the separation of a single airbag and preparing for the subsequent insertion of a single airbag; the output of the second telescopic rod 11... The end is also set towards the direction of the insert plate 4, and the output end is fixedly connected to the abutment rod 12. The diameter of the abutment rod 12 is adapted to the valve core inside the second inflation / deflation port a4 of the flexible vibration isolation airbag a limiting inflation airbag a3. It can be accurately inserted into the second inflation / deflation port a4 of the limiting inflation airbag a3 under the drive of the second telescopic rod 11. The valve core is pushed open so that the limiting inflation airbag a3 is automatically inflated under the elastic action of the internal spring a9. After inflation, the limiting inflation airbag a3 falls into the limiting groove 7 of the high-frequency vibration hammer 5, forming a vertical limit on the vibration isolation airbag body a1 contained in the insert plate 4, preventing the airbag from sliding upward with the vibration of the insert plate 4, and ensuring that the airbag can be driven downward synchronously with the insert plate 4.
[0057] The infeeding airbag inserting machine achieves flexible movement and positioning of the entire machine through the traveling device 1. After the material release roller 3 with the flexible vibration isolation airbag a wound on it is mounted, the airbag is smoothly transported by the guiding and conveying component. Then, through the linkage of the first telescopic rod 9 and the second telescopic rod 11, the single set of airbags is peeled off and the inflation limit is achieved. Then, it is connected to the pile tip 8. With the vibration force of the high-frequency vibrating hammer 5, the inserting plate 4 and the flexible vibration isolation airbag a inside are simultaneously driven into the soil between the construction area and the protection area. After the airbag is driven into the preset depth, the inflatable limiting airbag a3 is deflated and compressed by utilizing its retractable characteristic. Then, the inserting plate 4 is lifted upward by the braking component, leaving only the flexible vibration isolation airbag a and the pile tip 8 between the soil, forming a continuous vibration isolation protection barrier.
[0058] Further reference Figure 10 To ensure the stability and accuracy of the vertical movement of the high-frequency vibratory hammer 5 and the insert plate 4, the braking assembly includes a guide rod 13 set on the outer wall of the vertical truss 2 and a guide rail 14 fixedly connected to the inner wall of the high-frequency vibratory hammer 5. The guide rail 14 is a sliding sleeve structure adapted to the guide rod 13. The guide rail 14 is vertically slidable along the guide rod 13. The cooperation between the guide rod 13 and the guide rail 14 forms a linear guide, constraining the movement direction of the high-frequency vibratory hammer 5 and the insert plate 4, ensuring that they always move vertically, avoiding deviation due to vibration, and ensuring the verticality of the airbag insertion. The braking assembly also includes a winch 15 set on the traveling device 1. The winch 15 is a hydraulic winch 15 with a self-locking function. The traction cable in the winch 15 is a high-strength steel cable. The other end of the steel cable is guided by the guide wheel unit set on the top of the vertical truss 2 and fixedly connected to the top of the high-frequency vibratory hammer 5. The guide wheel unit can change the lifting direction of the steel cable to achieve the lifting of the high-frequency vibratory hammer 5.
[0059] The core function of the winch 15 is to lift and reset the high-frequency vibratory hammer 5 and the insert plate 4. After the airbag is driven to the preset depth, the winch 15 winds up the steel cable, which can quickly lift the high-frequency vibratory hammer 5 and the insert plate 4 upwards and remove them from the soil. It is worth noting that during the driving operation of the high-frequency vibratory hammer 5, the control room can control the winch 15 to appropriately loosen the steel cable, so that the steel cable is in a slightly loose state, to avoid the steel cable breaking due to the tensile stress generated by the high-frequency vibration, and at the same time to prevent the steel cable from interfering with the vertical vibration of the high-frequency vibratory hammer 5, thus ensuring the smooth progress of the driving operation.
[0060] Continue to refer to Figure 10In this embodiment, the guiding and conveying assembly includes a top frame 16 fixed to the top of the vertical truss 2. The top frame 16 is a steel structure frame that is welded and fixed to the vertical truss 2, providing strong structural stability. Two main conveying rollers 17 are rotatably mounted on the top frame 16, with their axes parallel to each other and their surfaces treated with anti-slip material. Both main conveying rollers 17 are driven to rotate by a drive motor, and their rotation directions are opposite, enabling lateral conveying of the flexible vibration isolation airbag a held between them. The top frame 16 is also equipped with several inclined conveying rollers for supporting the flexible vibration isolation airbag a, which can continuously support the airbag released from the discharge roller 3, preventing the airbag from sagging due to its own weight and ensuring that the bottom of the airbag can fall into the through hole 6.
[0061] The clamping gap between the two main conveying rollers 17 can be adjusted according to the thickness of the flexible vibration isolation airbag a. The roller surface of the main conveying rollers 17 is made of rubber, which has a certain elasticity. During the conveying process, it will not apply too much squeezing force to the flexible vibration isolation airbag a. It only plays the role of conveying and guiding the direction, effectively preventing the airbag from being damaged or leaking due to squeezing, and ensuring the integrity of the airbag.
[0062] Furthermore, the guiding and conveying assembly also includes a sliding frame 18 that slides laterally along the top frame 16. The top frame 16 has a transverse groove that matches the sliding frame 18. The sliding frame 18 can be moved laterally along the top frame 16 by means of a slider cooperating with the groove. The top end of the aforementioned guide rod 13 is fixed below the sliding frame 18 and moves synchronously with the sliding frame 18. The sliding frame 18 has a cavity inside, and several auxiliary conveying rollers are rotatably arranged in the cavity. After the flexible vibration isolation airbag a is conveyed by the main conveying roller 17 and the inclined conveying roller, it is then lifted and guided by the auxiliary conveying rollers and falls vertically into the through hole 6 of the high-frequency vibrating hammer 5, and finally enters the receiving cavity of the insert plate 4. The setting of the auxiliary conveying rollers further ensures the vertical attitude of the airbag during the falling process.
[0063] A hydraulic telescopic rod is connected between the vertical truss 2 and the sliding frame 18. The telescopic direction of the hydraulic telescopic rod is the same as the sliding direction of the sliding frame 18. It can drive the sliding frame 18 to move laterally along the top frame 16, thereby driving the guide rod 13, the high-frequency vibrating hammer 5 and the insert plate 4 to make lateral fine adjustments simultaneously. As an auxiliary adjustment measure during construction, it can achieve adjustment and alignment when there is a slight deviation between the insert plate 4 and the area to be inserted, without moving the entire traveling equipment 1, which greatly improves the efficiency of construction positioning. At the same time, a connecting plate is fixedly connected to the outer wall of the sliding frame 18. The first telescopic rod 9 and the second telescopic rod 11 are fixed from top to bottom, so that the first telescopic rod 9 and the second telescopic rod 11 move synchronously with the sliding frame 18, ensuring that they always correspond to the position of the insert plate 4, and ensuring the accuracy of the action of the peeling plate 10 and the abutment rod 12.
[0064] refer to Figure 14In this embodiment, to achieve a detachable connection between the pile tip 8 and the flexible vibration isolation airbag a, a plug shell 19 is welded and fixed to the top of the pile tip 8. The plug shell 19 is a hollow cylindrical structure with an open top, and its inner diameter is adapted to the bottom outer diameter of the flexible vibration isolation airbag a body for insertion. At least one set of limiting holes 20 are opened on the side wall of the plug shell 19, and their positions correspond to the positions of the connecting ear holes a8 at the bottom of the flexible vibration isolation airbag a body. After the bottom end of the flexible vibration isolation airbag a is inserted into the plug shell 19, the bolt 21 is passed through the limiting holes 20 on the plug shell 19 and the connecting ear holes a8 on the airbag in sequence, and then a nut is threaded to the end of the bolt 21. Through the locking fit of the bolt 21 and the nut, the pile tip 8 and the flexible vibration isolation airbag a are connected as one unit.
[0065] This connection method allows the vibration force of the high-frequency vibratory hammer 5 to be transmitted to the pile tip 8 through the insert plate 4. Simultaneously, the vibration force is evenly transmitted to the soil through the pile tip 8, enabling the airbag to be driven into the soil. Disassembly is also convenient; when the airbag needs to be retrieved after construction, simply loosen the nut and pull out the bolt 21 to separate the pile tip 8 from the airbag, facilitating the reuse of the pile tip 8. During the driving process, the upper part of the flexible vibration isolation airbag a, through the cooperation of the inflated limiting airbag a3 and the limiting groove 7, forms a vertical limit. The lower part, through the gravity of the pile tip 8, forms a downward tensile force, ensuring that the airbag remains fully expanded during driving, guaranteeing that the airbag can fully exert its vibration isolation effect after being driven into the soil.
[0066] This invention also proposes a construction process for an intubation airbag plate insertion machine, which includes the following steps: S1. Based on the design drawings, measure and lay out the lines at the construction site to determine the insertion position of the flexible vibration isolation airbag a. S2, after deflating several flexible vibration isolation airbags a, connect them end to end and wind them into the feeding roller 3; install the feeding roller 3 onto the traveling device 1, drive the traveling device 1 to move to the area to be constructed, so that the insertion plate 4 is perpendicular to the area to be inserted, and complete the equipment positioning. S3, the first set of flexible vibration isolation airbags a is pulled through the main conveyor roller 17, and after the attitude is adjusted by the inclined conveyor roller and the auxiliary conveyor roller, it is aligned with the entrance of the cavity of the insert plate 4; the drive motor is started, and the airbags are lowered into the insert plate 4 through the main conveyor roller 17 until the limiting inflated airbag a3 approaches the limiting groove 7, and the conveying is stopped. S4, activate the second telescopic rod 11, causing the stop rod 12 to insert into the second inflation / deflation port a4 and open the valve core. The limiting expansion airbag a3 expands under the action of the spring a9. Then the second telescopic rod 11 retracts and the valve core closes. Activate the first telescopic rod 9, causing the peeling plate 10 to abut against the protective strip a5 between the airbag inside the insert plate 4 and the adjacent airbag above. Lower the insert plate 4 through the winch 15. The insert plate 4 drives the internal airbag to move down synchronously. With the help of the peeling plate 10, the protective strip a5 is peeled off from the airbag above, so that the expanded limiting expansion airbag a3 falls into the limiting groove 7, thereby achieving vertical limiting of the vibration isolation airbag body a1. S5, when the bottom of the insert plate 4 moves to above the soil surface of the area to be inserted, fix the pile tip 8 to the bottom of the airbag; continue to lower the insert plate 4, and when the pile tip 8 is close to the soil, start the high-frequency vibrating hammer 5 to drive the insert plate 4 to vibrate and move down, so that the pile tip 8 is inserted to the designed depth below the soil surface of the area to be inserted; after the high-frequency vibrating hammer 5 is placed at a set distance above the soil surface, stop vibrating. S6, insert the push rod into the second inflation / deflation port a4, squeeze the limiting expansion airbag a3 to contract and vent, remove the push rod and close the valve core; use the winch 15 to lift the insert plate 4 to the initial high position; S7, drive the traveling device 1 to the next insertion area, start the main conveying roller 17 to convey the subsequent flexible vibration isolation airbags a, repeat steps S4 to S6 to complete the insertion of all flexible vibration isolation airbags a; After the flexible vibration isolation airbags (S8) are installed, the compaction points are marked and dynamic compaction is carried out. After the dynamic compaction is completed, the vertical grooves formed are backfilled to restore the site to a flat state.
