Description

Technical Field

[0001] This invention relates to the field of high-pile wharf reinforcement, and in particular to a high-pile wharf reinforcement structure and reinforcement method. Background Technology

[0002] A stilt wharf is a facility used for ship berthing and cargo loading / unloading. It typically consists of a series of stilts vertically driven into the water, anchored to the seabed or riverbed and connected by beams or platforms. The design of stilt wharves can adapt to varying water depths and tidal changes, ensuring the safe berthing of ships and the handling of cargo.

[0003] High-pile wharves, as crucial facilities for ship berthing and cargo loading / unloading, have always played a vital role in ports and estuaries. However, with the development of the shipping industry and the continuous increase in ship size, the original wharf structures are gradually facing the problem of being unable to meet the berthing and mooring needs of large-tonnage vessels. Traditional wharf structures have demonstrated good stability and reliability in berthing operations for small or medium-sized vessels. However, with the emergence of ultra-large vessels, the tonnage and size of these vessels far exceed the capacity of traditional wharf structures, leading to situations where the original high-pile wharf structures cannot meet the berthing and mooring needs of large-tonnage vessels. This has severely limited the use of the original high-pile wharf structures, and the fact that the original high-pile wharf structures occupy prime locations has also resulted in a certain degree of waste of port resources. Therefore, this paper proposes a high-pile wharf reinforcement structure and its reinforcement method to solve the above problems. Summary of the Invention

[0004] The main objective of this invention is to provide a high-pile wharf reinforcement structure and reinforcement method to solve the problem that the original high-pile wharf structure cannot meet the berthing requirements of large-tonnage ships.

The width of the anti-torsion stop is greater than the width between the two anti-torsion limiting steel pipes, and a gap is reserved between the anti-torsion stop and the two anti-torsion limiting steel pipes.

[0015] In the preferred embodiment, the outer diameter of the insertion end of the anti-torsion steel pipe is smaller than the outer diameter of its rear side, forming a limiting step, and the insertion end of the anti-torsion steel pipe is provided with multiple retractable limiting components;

[0016] The anti-torsion stop includes a sleeve with an inner diameter that matches the insertion end of the anti-torsion steel pipe, an anti-torsion baffle plate set on the sleeve insertion end, multiple support stiffening plates set on the back of the anti-torsion baffle plate and between the sleeve, and a limiting groove set on the outside of the sleeve and corresponding to the retractable limiting component.

[0017] The retractable limiting component includes a receiving groove recessed inward and located outside the insertion end of the anti-torsion steel pipe, an end hinged to a stop limiting block in the receiving groove, several tension components located at the bottom of the stop limiting block, a locking plate located at the opening of the receiving groove and above the hinge end, and a locking groove located at the top of the hinge end of the stop limiting block, wherein the receiving groove and the stop limiting block are both compatible right-angled triangles;

[0018] The tension assembly includes a telescopic groove at the bottom of the contact limiting block, a sliding groove on the inner wall of the telescopic groove, a tension spring built into the telescopic groove, a contact rod at the end of the tension spring and extending to the outside of the telescopic groove, and sliders on both sides of the contact rod and slidably connected to the sliding groove, wherein the end of the contact rod is arc-shaped and contacts the bottom wall of the receiving groove.

[0019] In a preferred embodiment, the rubber fender structure includes a mounting base disposed on the outer wall of the steel pipe pile, and a Z-shaped rubber fender that is bolted to the mounting base.

[0020] In a preferred embodiment, a ladder assembly is also provided on the side of the steel platform assembly closest to the front edge of the existing wharf structure. The ladder assembly includes a ladder vertically installed on all the steel platform assemblies, a protective cage covering the outside of the ladder, and a rest platform installed on the side of the ladder and the protective cage.

[0021] The method includes:

[0022] S1. Insert three steel casings into the surface of the moderately weathered slate at the bottom of the river, then insert three steel pipe piles through the three steel casings and embed them into the moderately weathered slate, and then pour concrete into the bottom of the three steel pipe piles and the gap between the steel pipe piles and the steel casings.

[0023] S2. Install the bottom steel platform assembly. First, install the three clamping support components of the bottom steel platform assembly onto the three steel pipe piles in sequence. During installation, first install the arc ring to the predetermined position and ensure that the support plates on the three arc rings are aligned with the center point of the three steel pipe piles. Then, install the locking ring onto the arc ring and clamp the steel pipe piles into it. Then, complete the welding work. Next, weld the protective hoop plate on the outside of the steel pipe piles and complete the steel platform welding and concrete pouring process on the support plate. Ensure that the three steel pipe piles are located in the three semi-circular grooves of the steel platform respectively. Finally, install the three clamping support components located above onto the three steel pipe piles respectively using the above method.

[0024] S3. Install the anti-torsion limiting components corresponding to step S2. Weld the three sets of anti-torsion limiting steel pipes to the corresponding positions at the top or bottom of the steel platform and complete the concrete pouring process. Then, install the anti-torsion components on the three steel pipe piles in sequence. The specific installation method is as follows: First, weld the first reinforcing plate to the outlet of the through hole. Then, insert the insertion end of the anti-torsion steel pipe from the inlet of the through hole until the second reinforcing plate is attached to the outside of the steel pipe pile. Complete the welding work between the anti-torsion steel pipe and the first reinforcing plate, and the second reinforcing plate and the steel pipe pile. Then, fit the anti-torsion stop piece onto the insertion end of the anti-torsion steel pipe until the anti-torsion stop piece abuts against the limiting step of the anti-torsion steel pipe and the retractable limiting component is engaged with the limiting groove. Finally, complete the welding work between the anti-torsion stop piece and the anti-torsion steel pipe.

Detailed Implementation

[0048] Example 1

[0049] like Figure 1-16 As shown, the high-pile wharf reinforcement structure includes the existing wharf structure 1. Multiple separate reinforcement piers 2 are installed along the front line of the existing wharf structure 1. The specific dimensions, spacing, and number of the separate reinforcement piers 2 are determined based on the plan layout and structural form of the existing wharf structure 1. Each separate reinforcement pier 2 includes three steel pipe piles 3 with their bottom ends embedded in the riverbed. The connecting line between the centers of the three steel pipe piles 3 forms an equilateral triangle. Two of the steel pipe piles 3 are located on the front line side of the existing wharf structure 1. Multiple steel platform components 4 and anti-torsion limiting components 5 are vertically distributed between the three steel pipe piles 3. The steel platform components 4 and anti-torsion limiting components 5 correspond one-to-one. The multiple steel platform components 4 can be adapted to different water levels during different flood seasons. The anti-torsion limiting components 5 are used to enhance the anti-torsion effect between the separate reinforcement piers 2, thereby enhancing the overall stability. Multiple rubber fender structures 6 are vertically installed on the outer side of the steel pipe piles 3 away from the front line of the existing wharf structure 1 to buffer the impact force when ships berth.

[0050] It should be noted that expansion joints and settlement joints are set between the separated reinforced pier 2 and the existing wharf structure 1. The joint width can be determined according to the structural deformation conditions. Flexible materials should be used to fill the expansion joints. This is a common technical means in this field, so it will not be described in detail here.

[0051] In a preferred embodiment, the steel platform assembly 4 includes a steel platform support 41 horizontally disposed outside each steel pipe pile 3, and a steel platform 42 disposed between the three steel platform supports 41, wherein the steel platform 42 is placed between the three steel pipe piles 3 via the steel platform supports 41.

[0052] The steel platform 42 includes a hollow frame 421. Multiple supporting ribs 423 are welded into the internal cavity of the hollow frame 421, which is then filled with concrete. The supporting ribs 423 provide good support for the steel platform 42.

[0053] In addition, the hollow frame 421 is a hexagon, and three of its sides are provided with semicircular grooves 422 that are compatible with the steel pipe piles 3. The line connecting the center points of the three semicircular grooves 422 forms an equilateral triangle. During installation, the three steel pipe piles 3 are embedded in the three semicircular grooves 422 respectively. The equilateral triangle formed by the center points can effectively improve the overall stability.

[0054] The steel platform support 41 consists of two clamping support components set outside the steel pipe pile 3. The two clamping support components clamp the steel platform 42 in it and provide support force to the steel platform 42.

[0055] In a preferred embodiment, the clamping support component includes an arc-shaped ring 411 that can form a circular ring to surround the steel pipe pile 3 and a locking ring 415. Multiple support plates 412 are welded to the outer edge of the arc-shaped ring 411 near the edge of the steel platform 42. In this embodiment, there are three support plates 412, and the angle between the three support plates 412 is 70.8°. An arc-shaped pad 414 is welded to one side of the support plate 412 near the steel platform 42 to support the steel platform 42, and two stiffening plates 413 connected to the arc-shaped ring 411 are welded to the other side to improve the support of the support plate 412.

[0056] The connection points of the arc-shaped ring 411 and the locking ring 415 are respectively provided with matching T-shaped slots 416 and T-shaped plugs 417. The top of the T-shaped slot 416 is open and the bottom is closed, which facilitates the quick docking of the arc-shaped ring 411 and the locking ring 415 by inserting the T-shaped slot 416 and the T-shaped plug 417.

[0057] Both ends of the arc-shaped ring 411 and the locking ring 415 are provided with integrally formed and outwardly extending connecting plates 418. A fixing bolt 419 is provided between the two corresponding connecting plates 418. The connecting plates 418 are provided with holes for the fixing bolt 419 to pass through, so that the arc-shaped ring 411 and the locking ring 415 are locked together by the fixing bolt 419.

[0058] In use, by setting the support plate 412 on an arc-shaped ring 411, it is easy to install three support plates 412 at the same time and ensure that the three support plates 412 are on the same horizontal plane. In addition, by installing the locking ring 415, the arc-shaped ring 411 can be quickly locked in the installation position, which also facilitates the completion of subsequent welding work.

[0059] In this embodiment, the steel platform 42 is placed on the clamping support component located below, and a gap is reserved between it and the clamping support component above and the steel pipe pile 3 on the side. The steel pipe pile 3 is welded with a protective hoop plate 302 corresponding to the side of the steel platform 42. The upper and lower sides of the steel platform 42 are provided with a reinforcing pad plate 410 at the junction with the arc-shaped pad block 414, so that the steel platform 42 has a certain amount of room for movement, and avoids the expansion, contraction and deformation of the structure from affecting the overall stability.

[0060] In a preferred embodiment, the anti-torsion limiting component 5 is disposed at the top or bottom of the steel platform component 4. The overall anti-torsion effect can be improved by arranging the anti-torsion limiting components 5 of different steel platform components 4 in an alternating manner. In this embodiment, except for the topmost anti-torsion limiting component 5 which is disposed below the steel platform component 4, the other anti-torsion limiting components 5 are disposed above the steel platform component 4, which can effectively make the top steel platform component 4 more open.

[0061] In the preferred embodiment, the anti-torsion limiting component 5 includes three sets of anti-torsion limiting steel pipes 51 set at the top or bottom of the steel platform 42, and anti-torsion components 52 that pass through the three steel pipe piles 3 respectively. The three anti-torsion components 52 form a limiting structure with the three sets of anti-torsion limiting steel pipes 51 respectively.

[0062] Three sets of anti-torsion limiting steel pipes 51 are respectively close to three semi-circular grooves 422. There are two anti-torsion limiting steel pipes 51 in each set, and they are all filled with concrete.

[0063] In the preferred embodiment, the anti-torsion component 52 includes a through hole 301 on the steel pipe pile 3, a first reinforcing guard plate 523 welded to the outlet of the through hole 301, an anti-torsion steel pipe 521 passing through the through hole 301, a second reinforcing guard plate 522 welded to the outside of the anti-torsion steel pipe 521 and located at the inlet of the through hole 301, and an anti-torsion stop 524 fixed to the front end of the anti-torsion steel pipe 521. Each set of two anti-torsion limiting steel pipes 51 are located on both sides of the anti-torsion steel pipe 521 and close to the anti-torsion stop 524. The width of the anti-torsion stop 524 is greater than the width between the two anti-torsion limiting steel pipes 51. A gap is reserved between the anti-torsion stop 524 and the two anti-torsion limiting steel pipes 51. The anti-torsion effect is achieved through the abutment relationship formed between the anti-torsion stop 524 and the two anti-torsion limiting steel pipes 51.

[0064] Among them, the first reinforcing plate 523 and the second reinforcing plate 522 are both arc-shaped and adapted to the steel pipe pile 3.

[0065] In a preferred embodiment, the outer diameter of the insertion end of the anti-torsion steel pipe 521 is smaller than the outer diameter of its rear side, forming a limiting step, and the insertion end of the anti-torsion steel pipe 521 is provided with a plurality of retractable limiting components 525.

[0066] The anti-torsion stop 524 includes a sleeve 5241 with an inner diameter adapted to the insertion end of the anti-torsion steel pipe 521, an anti-torsion baffle 5242 welded to the insertion end of the sleeve 5241, multiple support stiffening plates 5243 welded to the back of the anti-torsion baffle 5242 and between the sleeve 5241, and a limiting groove 5244 disposed outside the sleeve 5241 and corresponding to the retractable limiting component 525. The support stiffening plates 5243 and the limiting groove 5244 are staggered. When the anti-torsion stop 524 is inserted into the insertion end of the anti-torsion steel pipe 521, its installation depth can be quickly positioned by the limiting step, and the initial fixation of the anti-torsion stop 524 is achieved by the snap-fit ​​relationship between the retractable limiting component 525 and the limiting groove 5244, which facilitates the subsequent welding work.

[0067] The retractable limiting component 525 includes a receiving groove 5251 recessed inward from the outside of the insertion end of the anti-torsion steel tube 521, an abutting limiting block 5253 hinged at the end in the receiving groove 5251, several tension components disposed at the bottom of the abutting limiting block 5253, a locking plate 5252 integrally disposed at the opening of the receiving groove 5251 and located above the hinge end, and a locking groove 5259 disposed at the top of the hinge end of the abutting limiting block 5253. The receiving groove 5251 and the abutting limiting block 5253 are both compatible right-angled triangles. The locking groove 5259 can abut against the locking plate 5252 while also preventing the abutting limiting block 5253 from being interfered with by the locking plate 5252 when it rotates.

[0068] In this embodiment, there are three tension components. The lengths of the three tension components are stepped and arranged at the bottom of the contact limiting block 5253. The tension components include a telescopic groove 5254 arranged at the bottom of the contact limiting block 5253, a sliding groove 5255 arranged on the inner wall surface of the telescopic groove 5254, a tension spring 5256 built into the telescopic groove 5254, an abutting rod 5257 arranged at the end of the tension spring 5256 and extending to the outside of the telescopic groove 5254, and a slider 5258 fixed on both sides of the abutting rod 5257 and slidably connected to the sliding groove 5255 respectively. The end of the abutting rod 5257 is arc-shaped and contacts the bottom wall of the receiving groove 5251.

[0069] In use, the abutting rod 5257 maintains contact with the bottom wall of the receiving groove 5251 through the tension of the tension spring 5256, keeping the abutting limit block 5253 in an open position under the restriction of the locking plate 5252, thereby fixing the anti-torsion stop 524. Simultaneously, during the insertion of the anti-torsion stop 524 and the passage of the anti-torsion steel pipe 521 through the through hole 301, the slope of the abutting limit block 5253 is subjected to abutment, compressing the tension assembly and retracting it into the receiving groove 5251. Figure 12-13 As shown.

[0070] In the preferred embodiment, the rubber fender structure 6 includes a mounting seat 601 disposed on the outer wall of the steel pipe pile 3. The mounting seat 601 is U-shaped to avoid the protruding anti-torsion steel pipe 521, and a Z-shaped rubber fender 602 that is bolted to the mounting seat 601, thereby mitigating the impact force when the ship docks.

[0071] In a preferred embodiment, a ladder assembly 7 is also provided on the side of the steel platform assembly 4 near the front edge of the existing wharf structure 1. The ladder assembly 7 includes a ladder 701 vertically arranged on all steel platform assemblies 4, a protective cage 702 covering the outside of the ladder 701, and a rest platform 703 arranged on the side of the ladder 701 and the protective cage 702.

Then concrete is poured into the bottom of the three steel pipe piles 3 and the gap between the steel pipe piles 3 and the steel casings.

[0074] S2. Install the bottom steel platform component 4. First, install the three clamping support components of the bottom steel platform component 4 on the three steel pipe piles 3 in sequence. During installation, first install the arc ring 411 to the predetermined position and ensure that the support plate 412 on the three arc rings 411 is aligned with the center point of the three steel pipe piles 3. Then, install the locking ring 415 on the arc ring 411 and clamp the steel pipe pile 3 in it. Then, complete the welding work. Then, weld the protective hoop plate 302 on the outside of the steel pipe pile 3. Complete the welding and concrete pouring process of the steel platform 42 on the support plate 412 and ensure that the three steel pipe piles 3 are respectively located in the three semi-circular grooves 422 of the steel platform 42. Finally, install the three clamping support components on the top of the steel pipe piles 3 respectively using the above method.

[0075] S3. Install the anti-torsion limiting component 5 corresponding to step S2. Weld the three sets of anti-torsion limiting steel pipes 51 to the corresponding positions at the top or bottom of the steel platform 42, and complete the concrete pouring process. Then, install the anti-torsion component 52 on the three steel pipe piles 3 in sequence. The specific installation method is as follows: First, weld the first reinforcing plate 523 to the outlet of the through hole 301. Then, insert the insertion end of the anti-torsion steel pipe 521 from the inlet of the through hole 301 until the second... The reinforcing plate 522 is attached to the outside of the steel pipe pile 3, and the welding work of the anti-torsion steel pipe 521 to the first reinforcing plate 523 and the second reinforcing plate 522 to the steel pipe pile 3 is completed. Then, the anti-torsion stop 524 is fitted to the insertion end of the anti-torsion steel pipe 521 until the anti-torsion stop 524 abuts against the limiting step of the anti-torsion steel pipe 521, and the retractable limiting component 525 is engaged with the limiting groove 5244. Finally, the welding work of the anti-torsion stop 524 and the anti-torsion steel pipe 521 is completed.
