[0025] Compared with the prior art, the advantages of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use;

[0026] 1. Equipped with a load-bearing support structure, this structure, through the cooperation of support seats, connecting blocks, hanging plates, brackets, connecting rods, sliding cylinders, and clamping rods, can construct an elastic and adjustable support and protection structure. This provides stable elastic support to the hangers, achieving permanent support for the pipeline and significantly improving its stability. Furthermore, the corrugated pipe's connecting and guiding function, combined with limit seats, vertical boxes, plug plates, tie rods, and guide pipes, allows for the initial conversion and utilization of pipeline gravity. It automatically adapts to the pipeline diameter, limits and locks the pipeline, and provides ample elastic support, effectively achieving comprehensive support and protection for the pipeline. This significantly improves the effectiveness of the support work and effectively prevents the pipeline from shifting due to external impacts during subsequent use.

[0027] By combining the bottom cavity, connecting seat, strut, round plug, clamp, reinforcing plate, and pile, a pit limiting structure can be constructed, which can further transform and utilize gravity, turning the pipeline's self-weight into elastic support and protection force. It can automatically limit the pipeline's orientation according to the width, depth, and diameter of the pit, greatly improving the flexibility and convenience of pipeline installation. While improving the compatibility and adaptability of the pipeline protection system, it can also enhance the support and protection effect and compact and reinforce the soil on the sidewall of the pit. At the same time, it can use external interference impact force to strengthen the pipeline's support and protection work, so that the support and protection force rises and falls synchronously with the impact load, realizing multiple dispersion and absorption of external impact loads. It can also use external impact loads to further reinforce the sidewall of the pit, improving the pipeline's stability. In addition, the communicating vessel structure formed by the top cavity, strut, linkage piston, sliding cavity, side pipe, and reinforcing sliding rod can offset and compensate for the pipeline's settlement in the pit, further enhancing the pipeline's stability and preventing pipeline misalignment damage.

[0028] 2. Equipped with a protective installation mechanism, the foundation pit reinforcement structure can be constructed through the cooperation of base plate, strip seat, insert pipe, support plug and reinforcing cylinder. In addition, the limiting and adjusting functions of base, guide rod, sliding box, threaded rod and strip plate can quickly limit and reinforce the side wall of the foundation pit during pipeline construction. It can flexibly adapt to different geological environments and construction conditions, and efficiently adapt to different foundation pit widths and depths, realizing rapid support of the foundation pit. While expanding the adaptability and effective application range of the system, it indirectly realizes the temporary protection of the pipeline, effectively ensuring the safety and stability of the pipeline during construction, and equivalently improving the effectiveness of pipeline support and protection. At the same time, the protective installation mechanism can be repeatedly recycled, effectively improving economy and environmental protection.

[0029] By combining ball head seats, column cylinders, support columns, sliders, threaded heads, and threaded cylinders, an auxiliary limiting structure can be constructed. On the one hand, it can achieve double elastic support for the base plate, improving the effectiveness of the foundation pit support work and ensuring the reliability of pipeline construction. On the other hand, it can cooperate with vertical holes, sliding pipes, double connecting pipes, bottom pipes, connecting boxes, and threaded nozzles to form a pneumatic linkage structure. In addition, with the adjustment functions of pressure delivery plates, drive rods, delivery pipes, extraction valves, and pressure delivery valves, the flexibility and convenience of the device's transportation, disassembly, and installation can be ensured, while making the base plates on both sides form a linked whole. This allows for uniform adjustment of the base plates, improving the ease of base plate installation, effectively enhancing the stress uniformity of the side walls of the foundation pit, improving the working balance of the foundation pit side wall reinforcement, and dispersing and dissipating external impact forces during construction to avoid stress concentration, greatly improving the effectiveness of protection.

[0030] In summary, this pipeline protection system can absorb and transform the gravity of the pipeline and external impact loads, providing temporary reinforcement and protection for the foundation pit during pipeline construction and permanent elastic support and protection for the pipeline during subsequent use. It can also disperse and absorb external impact forces, providing elastic locking support to the pipeline while compensating for pipeline settlement, significantly improving pipeline stability and qualitatively enhancing the pipeline's support and protection effect.

The base plate 301 is then engaged with the corresponding number of reinforcing plates 213. The corresponding load-bearing support structure 200 is then sent into the foundation pit through the base plate 301, so that the base plate 301 fits against the pit walls on both sides of the foundation pit. During this process, the base plate 301 can be initially limited and fixed by fixing the base 318 to the corresponding position on the ground outside the foundation pit.

[0062] In the aforementioned process, the installation sequence of the load support structure 200 can be limited according to actual construction habits and construction convenience. After each base plate 301 is put into the foundation pit in sequence, each load support structure 200 can be sent into the foundation pit in sequence. By adjusting the threaded rod 321 accordingly, the reinforcing plates 213 on both sides can be engaged with the base plates 301 on both sides in sequence.

[0063] After fixing the base 318, rotate the threaded rod 321 to drive the strip 327 to move, forcing the sliding box 320 to drag the strip seat 302 to one side of the sliding box 320 under the push of the strip 327. This allows the base plate 301 to press against the pit sidewall with greater force under the drive of the strip seat 302. The position of the base plate 301 is then further adjusted and fixed. It should be noted that if the base plate 301 is installed first and then the load support structure 200 is installed, the position of the base plate 301 should be further adjusted and fixed after the reinforcing plates 213 on both sides are engaged with the base plates 301 on both sides. During the installation of the load support structure 200, the position of the base plate 301 can be adjusted by rotating the threaded rod 321 in the opposite direction to provide sufficient installation space for the reinforcing plates 213.

[0064] During the process of further adjusting and fixing the orientation of the substrate 301, the strip seats 302 on both sides of the pit should be aligned as much as possible. The strip seats 302 on both sides of the pit should be connected end to end in sequence through the threaded tube 32 and threaded joint 33. The built-in switches of the threaded tube 32 and threaded joint 33 except for the two ends should be opened so that the inner cavities of the strip seats 302 on both sides are connected through the threaded tube 32 and threaded joint 33 respectively.

[0065] Next, rotate the threaded cylinder 312 and install the corresponding threaded head 311 on the threaded cylinder 312 through the threaded head 311 and the threaded cylinder 312. Then, connect the corresponding number of column cylinders 308 and column supports 309 to the ball head seats 307 on both sides in sequence through the threaded head 311 and the threaded head 317 on the corresponding connecting box 316 through the double pipe 314. This connects the space inside the column cylinder 308 between the two sliders 310 and the space inside the reinforcing cylinder 305 at the bottom of the support 304, and further enables the inner cavity of each seat 302 on both sides of the pit to be connected.

[0066] In the initial state, under the action of the top air pressure, the torpedo 304 will drag the insertion tube 303, so that the insertion tube 303 is completely retracted into the reinforcing cylinder 305. After the installation of each cylinder 308 is completed, a steel pipe can be sleeved at the end of the drive rod 323 and the drive rod 323 can be manually moved back and forth, or the drive rod 323 can be moved back and forth by external machinery to drive the pressure plate 322 to move back and forth inside the sliding box 320. Under the flow restriction action of the extraction valve 325 and the pressure valve 326, the external air is drawn into the sliding box 320 through the extraction valve 325.

[0067] Subsequently, the airflow is pressed into the strip seat 302 through the delivery pipe 324 and the pressure valve 326. Then, under the guidance of the insertion pipe 303 and the vertical hole 306, the airflow flows into the space inside the reinforcing cylinder 305 located at the bottom of the support plug 304, providing elastic support to the bottom of the support plug 304, offsetting the air pressure on the top of the support plug 304, and forcing the support plug 304 to rise relative to the reinforcing cylinder 305. Furthermore, the reinforcing cylinder 305 will drag the base plate 301, forcing the base plate 301 to press down along the pit, adjusting the height of the base plate 301 relative to the pit. Further, under the action of the reinforcing plate 213, the position of each support seat 201 can be initially adjusted and limited to achieve the initial adjustment of the installation orientation of the subsequent pipeline.

[0068] During this process, with the bottom tube 315 connected, the airflow will flow into the connecting box 316, and then through the threaded nozzle 317 and the double pipe 314 connected, it will flow into the space between the two sliders 310 inside each cylinder 308 via the slide pipe 313, forcing the sliders 310 to push the pillars 309 on both sides to move away under the action of air pressure, and providing elastic support to the base plates 301 on both sides through the ball head seat 307, thus achieving double support for the base plates 301 on both sides.

[0069] During this process, since the strip seats 302, reinforcing cylinders 305 and column cylinders 308 on both sides are in a conductive state, all the base plates 301 on both sides of the foundation pit can be adjusted synchronously by moving the drive rod 323 on any one of the sliding boxes 320. In order to speed up the construction progress, the drive rods 323 on multiple sliding boxes 320 can be moved synchronously to shorten the required adjustment time and complete the final adjustment and fixing of each base plate 301 on both sides of the foundation pit.

[0070] Similarly, since the strip seats 302, reinforcing cylinders 305 and column cylinders 308 on both sides are in a conductive state, during the subsequent construction process, the impact pressure on each base plate 301 will be converted into airflow pressure, and with the flow of airflow, it will be dispersed and act on the sliders 310 in each column cylinder 308, which will become each support column 309 to provide elastic support force to each base plate 301, and further applied to each side wall of the foundation pit through each base plate 301. Finally, the impact force will be dispersed, absorbed and resolved through the side wall of the foundation pit, ensuring the stability of each base plate 301 and the foundation pit structure.

[0071] After completing the above installation and adjustment work, the pipeline installation work can be carried out. Using an external hoisting device, the pipeline is sent into the foundation pit and aligned with the hanger 209. The pipeline is placed on the hanger 209. Under the gravity of the pipeline, the hanger 209 will sink accordingly. Under the linkage of the sliding cylinder 206 and the clamping rod 207, the connecting block 202 is driven to slide down the support seat 201, forcing the hanging plate 203 and the support plate 204 to slide down synchronously relative to the support seat 201 under the drive of the connecting rod 205.

[0072] During this process, when the hanging plate 203 slides down relative to the support seat 201, the non-Newtonian fluid inside the top cavity 215 will flow into the sliding cavity 219 through the side pipe 220 under the conduction of the side pipe 220. This forces the linkage piston 218 to rise along the sliding cavity 219 under the compression of the non-Newtonian fluid. Then, under the drag of the support rod 217, the clamp 212 will drive the support seat 1 to rise through the support rod 210, which will compensate for the distance of the descent of the support seat 201, offset the actual sinking of the pipeline, and keep the support seat 201 at the initial set height.

[0073] Meanwhile, under the conduction of the bellows 208, the non-Newtonian fluid inside the top cavity 215 will flow into the slide cylinder 206 through the bellows 208, forcing the two hangers 209 to move closer to each other along the reinforcing slide rod 226 under the push of the clamping rod 207. With the connection of the conduit 225, the non-Newtonian fluid inside the top cavity 215 will flow into the vertical box 222 through the conduit 225, forcing the plug plate 223 to slide upward relative to the vertical box 222. Then, under the pull of the pull rod 224, the limiting seat 221 will move closer to the hanger 209, and finally the hanger 209 and the limiting seat 221 will simultaneously lock the pipe, using the weight of the pipe to lock and fix the pipe relatively, which is equivalent to providing the pipe with all-round support and protection.

[0074] During the process of the support plate 204 sliding down relative to the support seat 201, it will press the non-Newtonian fluid inside the bottom cavity 216 into the gap between the two round plugs 211 of the support seat 1 through the connecting seat 214, forcing the support rods 210 on both sides to move away from each other under the push of the round plugs 211 on both sides. Then, under the limit of the locking strip 212, each reinforcing plate 213 on both sides of the pit will be pushed towards the pit sidewall with greater force, so that the pile 227 is more stably locked into the pit sidewall, and the reinforcing plate 213 is locked and limited by the gravity of the pipeline, and the pit sidewall is further compacted.

[0075] Similarly, during the subsequent use of the pipeline, since the hanger 209 and the limit seat 221 simultaneously hold the pipeline in place, the impact force acting on the pipeline will combine with the pipeline's gravity to form a resultant force, which is synchronously transmitted to the hanger 209 and acts on the non-Newtonian fluid. The non-Newtonian fluid can initially buffer the impact force and can disperse the impact force to the side walls of the pit on both sides during the flow process. While compacting the side walls of the pit on both sides, it makes the pile 227 more stably engaged with the side walls of the pit, thus doubly absorbing and dispersing the impact force. In addition, the communicating vessel structure formed by the linkage piston 218, sliding cavity 219, side pipe 220, top cavity 215 and hanging plate 203 can offset and compensate for the pipeline's settlement in the pit, ensuring the stability of the pipeline.

[0076] After the pipeline is stably suspended and locked on the support 201, the threaded ring 24 is rotated to drive the screw 25 to move away, so that the bottom plate 26 moves away from the threaded ring 24 and finally comes into contact with the ground at the bottom of the pit. Then the threaded ring 24 is rotated to increase the extension of the screw 25. The top plate 23 will squeeze the non-Newtonian fluid at the top of the regulating box 21 under the action of the vertical cylinder 22, giving the support 1 elastic support and distributing the pressure given to it by the pipeline.

[0077] Since the pipeline is already in a balanced state during the aforementioned installation and adjustment process, the top plate 23 can easily break this balance state through the disturbance force of the support 1 provided by the non-Newtonian fluid, driving the pipeline to rise and further fine-tuning and compensating for the suspension height of the pipeline. The top plate 23 also distributes part of the pipeline's weight to achieve a new balance state, allowing the pipeline to be stably suspended at the specified height. At the same time, since the non-Newtonian fluid inside the regulating box 21 can flow into the gap between the two round plugs 211 in the support 1, it compensates for the non-Newtonian fluid in the gap between the two round plugs 211 and transmits the pressure to the side walls on both sides of the pit without affecting the support effect of the load support structure 200, thus achieving permanent support for the pipeline.

[0078] After installing and fixing each pipe in sequence using the aforementioned method, open the pressure relief valve 31 to allow the high-pressure gas inside the strip seat 302 to be discharged, thereby releasing the high-pressure limiting support of the hanging seat 209 at the slider 310. By rotating the threaded rod 321 in the opposite direction, the base plates 301 on both sides of the pit can be driven to move closer to each other. Finally, the limiting on the base 318 can be released, and the base plate 301 can be removed from the pit. The protective installation mechanism 300 can then be recycled and reused. Finally, the backfilling of the pit is completed, thus completing the construction work.
