Closed water structure of a ship berthing component of a high-pile wharf

Abstract

This utility model discloses a watertight structure for berthing components of a high-pile wharf, including a pre-embedded steel plate and a fender steel base. The rear side of the fender steel base is fixedly connected to the pre-embedded steel plate, and the front side of the pre-embedded steel plate is connected to a split fender body. The front side of the split fender body is fixedly connected to a buffer end plate, and fan-shaped rubber plates are equidistantly embedded and fixed on the front side of the buffer end plate. By setting a front mounting plate and connecting to the fender steel base, radial pressure is applied by the edge expansion bolts that transmit the ship's impact force. The system is pre-embedded in concrete, anchoring the entire system surface with a rubber waterstop strip, filling micro-cracks in the concrete, and blocking capillary seepage paths. The system can quickly assemble and disassemble the first rubber fender connected to the buffer end plate and the second rubber fender connected to the front side of the fender steel base. The double nuts are tightened in opposite directions to generate axial pressure, forcing epoxy mortar to squeeze into micro-defects to achieve nano-level filling, which can perform static pre-sealing.

Description

Technical Field

[0001] This utility model relates to the technical field of watertight structures for berthing components, specifically to watertight structures for berthing components of high-pile wharves. Background Technology

[0002] A berthing structure is a buffer device located at the edge of a wharf. Fenders (such as rubber fenders, steel fenders, or wooden fenders) are typically placed on the edge of the wharf or on the berthing structure itself to mitigate the impact forces between ships and the wharf, or between ships themselves, during berthing or mooring, thus reducing or eliminating damage to the ships and wharf during these processes. Berthing structures are an important component of high-pile beam-slab structures or high-pile pier-type wharf structures. Generally, the bottom elevation of the berthing structure is close to or lower than the design bottom water level, and half of its volume is submerged in seawater. To ensure the construction quality of the berthing structure, a prefabricated berthing structure followed by on-site installation is typically used.

[0003] In the prior art, application number 202022148992.6 discloses a bolt-mounted rubber fender; it includes a protective body, a structural component installed on the hull, a support component supporting the protective body, bolts fixing the protective body, and sealant covering the bolts; the support component is installed on the structural component; the bolts pass through the protective body and the support component respectively; the sealant fills the protective body; the above device only covers the outside of the bolts, only sealing the part of the bolts exposed on the concrete surface, but seawater can seep in through the annular gap between the bolt and the hole wall, and areas where the threads are not tightly engaged; and gaps still exist around the berthing components, concrete wharves, and embedded steel plates, allowing seawater to seep into the gaps, corroding the internal steel bars and embedded parts, leading to structural damage.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In response to the problems in related technologies, this utility model proposes a watertight structure for the berthing components of a high-pile wharf, in order to overcome the aforementioned technical problems existing in the prior art.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] The watertight structure of the berthing components of the high-pile wharf includes a pre-embedded steel plate and a fender steel base. The rear side of the fender steel base is fixedly connected to the pre-embedded steel plate, and the front side of the pre-embedded steel plate is connected to a split fender body. The front side of the split fender body is fixedly connected to a buffer end plate, and the front side of the buffer end plate is equidistantly embedded with fan-shaped rubber plates.

[0008] Preferably, the embedded steel plate includes a front mounting plate and a rear mounting plate, the rear mounting plate is disposed behind the front mounting plate, the front edge of the front mounting plate is provided with expansion bolts at equal intervals, and a rubber gasket ring is sleeved and fixed on the outer side of the rear mounting plate.

[0009] Preferably, the rubber gasket ring has threaded holes equidistantly through its front edge, the expansion bolts are threaded to match the threaded holes, and the outer wall of the rear mounting plate is wrapped with a rubber waterstop.

[0010] Preferably, the split-type fender body includes a first rubber fender and a second rubber fender, the second rubber fender being disposed on the rear side of the first rubber fender and fixedly connected to the front side of the fender steel base.

[0011] Preferably, connecting plates are fixedly connected to the front outer wall of the first rubber fender and the front outer wall of the second rubber fender, respectively. Reinforcing ribs are fixedly connected to the bottom of both sides of the connecting plates, and the reinforcing ribs are fixedly connected to the outer walls of the first rubber fender and the second rubber fender.

[0012] Preferably, a hexagonal prism is fixedly connected to the rear side of the first rubber fender, and a hexagonal groove is cut out on the front side of the second rubber fender, wherein the hexagonal groove and the hexagonal prism are matched and engaged for fixation.

[0013] Preferably, each of the connecting plates has a through threaded hole on its front side, and the connecting plates are connected by a bolted water-tight assembly through the through threaded holes.

[0014] Preferably, the bolt water-tight assembly includes a threaded post and a locking nut. The locking nut is threaded to the front and rear ends of the threaded post, and a waterproof sleeve is fitted on the outer wall of the threaded post. The waterproof sleeve is specifically an internally threaded tubular structure, and its inner wall is coated with epoxy mortar, just like the inner wall of the locking nut. The waterproof sleeve is threadedly connected to the threaded post.

[0015] The beneficial effects of this utility model are as follows: By setting a front mounting plate, connecting the fender steel base, and applying radial pressure with the edge expansion bolts to transmit the ship's impact force, the rubber gasket ring is squeezed to achieve the first interface seal. Pre-embedded in concrete, the entire system surface is anchored with a rubber waterstop strip, filling micro-cracks in the concrete and blocking capillary seepage paths. This allows for the rapid assembly and disassembly of the first rubber fender connected to the buffer end plate and the second rubber fender connected to the front side of the fender steel base. Epoxy mortar is injected into the inner wall of the waterproof sleeve and the inner wall of the locking nut. During the screwing of the threaded post and the waterproof sleeve… Uncured epoxy mortar flows and fills the thread gaps. The double nuts tightening in opposite directions generate axial pressure, forcing the epoxy mortar to squeeze into microscopic defects, achieving nanoscale gap filling. Static pre-sealing can be performed. When the fender is under pressure, the threaded column is under tension, and the internal thread of the waterproof sleeve tends to separate from the threaded column. The epoxy mortar is subjected to shear force. Due to its high bonding strength, it inhibits the opening of the thread gap and keeps the sealing interface intact. Similarly, with reverse vibration, the fender resets, the threaded column is under pressure, and the locking nut further compresses the epoxy mortar layer, increasing the pressure on the sealing interface. Moreover, the epoxy mortar softens at 150℃, enabling non-destructive bolt disassembly. Attached Figure Description

The rear side of the fender steel base 2 is fixedly connected to the pre-embedded steel plate 1. A split-type fender body 3 is connected to the front side of the pre-embedded steel plate 1. A buffer end plate 4 is fixedly connected to the front side of the split-type fender body 3. A fan-shaped rubber plate 5 is embedded and fixed at equal intervals on the front side of the buffer end plate 4. The pre-embedded steel plate 1 includes a front mounting plate 6 and a rear mounting plate 7. The rear mounting plate 7 is located behind the front mounting plate 6. Expansion bolts 8 are provided at equal intervals through the front edge of the front mounting plate 6. A rubber gasket ring 9 is sleeved and fixed on the outer side of the rear mounting plate 7. Threaded holes 10 are provided at equal intervals through the front edge of the rubber gasket ring 9. Bolt 8 is threaded to match threaded hole 10. Rubber waterstop 11 is wrapped around the outer wall of rear mounting plate 7. By setting front mounting plate 6, connecting fender steel base 2, the radial pressure is applied by edge expansion bolt 8 to transmit ship impact force, and the rubber gasket 9 is squeezed to achieve the first interface seal. It is embedded in concrete and anchors the entire system surface. The rubber waterstop 11 is wrapped around the surface, fills the concrete micro-cracks, and blocks the capillary seepage path. By setting rubber gasket 9, it is compressed and deformed by expansion bolt 8 and compressed by bolt preload to form an interface watertight barrier to resist hydrostatic pressure. Fan-shaped rubber plates 5 are set at equal intervals on the front side of buffer end plate 4 to disperse ship impact force and guide water flow away from the groove between plates.

[0027] Example 2

[0028] like Figure 1-4 As shown, the watertight structure of the berthing component of the high-pile wharf according to an embodiment of this utility model includes a pre-embedded steel plate 1 and a fender steel base 2. The rear side of the fender steel base 2 is fixedly connected to the pre-embedded steel plate 1. A split-type fender body 3 is connected to the front side of the pre-embedded steel plate 1. A buffer end plate 4 is fixedly connected to the front side of the split-type fender body 3. Fan-shaped rubber plates 5 are equidistantly embedded and fixed to the front side of the buffer end plate 4. The split-type fender body 3 includes a first rubber fender 12 and a second rubber fender 13. The second rubber fender 13 is located behind the first rubber fender 12 and is fixedly connected to the front side of the fender steel base 2. Connecting plates 14 are fixedly connected to the front outer wall of the first rubber fender 12 and the front outer wall of the second rubber fender 13, respectively. Reinforcing ribs 15 are fixedly connected to the bottom of both sides of the connecting plates 14. The reinforcing ribs 15 are fixedly connected to the outer walls of the first rubber fender 12 and the second rubber fender 13. A hexagonal prism 23 is fixedly connected to the rear side of the first rubber fender 12. The front side of the second rubber fender 13 has a hexagonal groove 16, which is matched and engaged with the hexagonal prism 23. The front side of the connecting plate 14 is provided with threaded through holes 17, and the connecting plates 14 are connected to each other through the threaded through holes 17 by bolt water-tight assembly 18. The first rubber fender 12 of the split fender body 3 is matched and engaged with the hexagonal groove 16 on the front side of the second rubber fender 13 by the hexagonal prism 23. Then, the connecting plates 14 on the first rubber fender 12 and the second rubber fender 13 are connected and fixed by bolt water-tight assembly 18. The first rubber fender 12 connected to the buffer end plate 4 and the second rubber fender 13 connected to the front side of the fender steel base 2 can be quickly assembled and disassembled. When the front face of the berthing structure is damaged by impact, it can be flexibly disassembled and replaced, avoiding direct disassembly from the concrete of the dock and then re-construction and drilling, which greatly improves the disassembly and replacement effect.

[0029] Example 3

[0030] like Figure 1-4As shown, the watertight structure of the berthing component of the high-pile wharf according to an embodiment of the present invention includes a pre-embedded steel plate 1 and a fender steel base 2. The rear side of the fender steel base 2 is fixedly connected to the pre-embedded steel plate 1. A split-type fender body 3 is connected to the front side of the pre-embedded steel plate 1. A buffer end plate 4 is fixedly connected to the front side of the split-type fender body 3. Fan-shaped rubber plates 5 are equidistantly embedded and fixed on the front side of the buffer end plate 4. The bolt watertight assembly 18 includes a threaded post 19 and a locking nut 20. The locking nut 20 is threadedly connected to the front and rear ends of the threaded post 19, and a locking nut 20 is sleeved on the outer wall of the threaded post 19. The waterproof sleeve 21 is specifically a threaded tubular structure, with its inner wall coated with epoxy mortar 22, similar to that of the locking nut 20. The waterproof sleeve 21 is threadedly connected to the threaded post 19. After splicing the first rubber fender 12 and the second rubber fender 13, and aligning the positions of the connecting plates 14, the threaded post 19 can be screwed into the threaded through hole 17 of the connecting plate 14 on the first rubber fender 12, and the waterproof sleeve 21 can be screwed in. Then, the rear end of the threaded post 19 is screwed through the connecting plate 14 on the second rubber fender 13. The threaded through hole 17 is then screwed onto the outside of the threaded post 19, and then the locking nuts 20 are screwed onto the front and rear ends of the threaded post 19. This allows for the quick assembly and positioning of the first rubber fender 12 and the second rubber fender 13. The outer wall of the threaded post 19 and its front and rear ends are covered by waterproof sleeves 21 and locking nuts 20, respectively. The spiral thread path extends the seawater penetration distance. Epoxy mortar 22 is injected into the inner wall of the waterproof sleeve 21 and the inner wall of the locking nut 20. During the screwing process of the threaded post 19 and the waterproof sleeve 21, the uncured epoxy mortar flows and fills the thread gaps. Tightening the nuts in opposite directions generates axial pressure, forcing the epoxy mortar to squeeze into microscopic defects, achieving nanoscale gap filling, which can perform static pre-sealing. The fender is under pressure, the threaded post 19 is under tension, and the internal thread of the waterproof sleeve 21 tends to separate from the threaded post 19. The epoxy mortar 22 is subjected to shear force, and its high bonding strength inhibits the opening of the thread gap, keeping the sealing interface intact. Similarly, with reverse vibration, the fender resets, the threaded post 19 is under pressure, and the locking nut 20 further compresses the epoxy mortar layer, increasing the pressure on the sealing interface. Moreover, the epoxy mortar softens at 150℃, enabling non-destructive bolt disassembly.

[0031] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, by setting the front mounting plate 6, connecting the fender steel base 2, and transmitting the ship's impact force, the edge expansion bolts 8 apply radial pressure, squeezing the rubber gasket ring 9 to achieve the first interface seal, which is pre-embedded in concrete, anchoring the entire system surface, and wrapping the rubber waterstop 11 to fill the micro-cracks in the concrete and block the capillary seepage path. By setting the rubber gasket ring 9, it is compressed and deformed by the expansion bolts 8 and compressed by the bolt preload, forming an interface watertight barrier to resist hydrostatic pressure. The first rubber fender 12 of the split fender body 3 The hexagonal prism 23 is matched and engaged with the hexagonal groove 16 excavated on the front side of the second rubber fender 13. Then, the connecting plates 14 on the first rubber fender 12 and the second rubber fender 13 are connected and fixed by bolt water-tight assembly 18. This allows for the rapid assembly and disassembly of the first rubber fender 12 connected to the buffer end plate 4 and the second rubber fender 13 connected to the front side of the fender steel base 2. In the event of damage to the front face of the berthing structure due to impact, it can be flexibly disassembled and replaced. After splicing the first rubber fender 12 and the second rubber fender 13, it can be... After aligning the connecting plate 14, the threaded post 19 can be screwed into the threaded through hole 17 of the connecting plate 14 on the first rubber fender 12, and the waterproof sleeve 21 can be screwed in. Then, the rear end of the threaded post 19 is screwed through the outside of the threaded through hole 17 of the connecting plate 14 on the second rubber fender 13. Then, the locking nuts 20 are screwed in at both ends of the threaded post 19. The first rubber fender 12 and the second rubber fender 13 can be quickly assembled and positioned. The outer wall of the threaded post 19 and its front and rear ends are covered by the waterproof sleeve 21 and the locking nuts 20, respectively. During the screwing process of 9 and the waterproof sleeve 21, the uncured epoxy mortar flows and fills the thread gap. The double nuts tighten in opposite directions, generating axial pressure, which forces the epoxy mortar to squeeze into the micro-defects, achieving nano-level gap filling. Static pre-sealing can be performed. The fender is under pressure, the threaded column 19 is under tension, and the internal thread of the waterproof sleeve 21 and the threaded column 19 tend to separate. The epoxy mortar 22 is subjected to shear force. Due to its high bonding strength, it inhibits the opening of the thread gap and keeps the sealing interface intact. Similarly, with reverse vibration, the fender resets, the threaded column 19 is under pressure, and the locking nut 20 further compresses the epoxy mortar layer, increasing the pressure on the sealing interface.
