Abstract
Description
Technical Field
[0001] This invention relates to the field of water structure technology, specifically to a heavy-duty floating platform, providing a solution for large floating platforms, heavy-duty floating corridors, heavy-duty self-floating wharves, passive anti-collision facilities for bridge piers, etc. Background Technology
[0002] my country has a vast water area, and with the rapid development of the domestic economy, the demand for structures within aquatic environments is increasing. For example, the market for floating bridges, docks, and floating platforms suitable for the tourism industry, as well as passive collision protection facilities for bridge piers used in water protection, is growing. However, these structures within aquatic environments also present some problems:
[0003] (1) Wharf: The structural forms include gravity type, high pile type and sheet pile type. Its disadvantages are that it requires the construction of a fixed building on the foundation, and the construction period is long; the elevation of the wharf road surface is fixed, and the adaptability to water level is poor; it is inconvenient for later maintenance. (2) Floating platform: It is mainly realized by splicing and combining pontoons. Its disadvantages are that it is made of polymer plastic and can only be used for sightseeing, tourism, small ferry and other scenarios. It is not suitable for heavy load-bearing, and the durability of polymer plastic in outdoor environment is poor. (3) Pier protection: It adopts integral molding. Its disadvantages are that the molded components are large in size, and the molding, hoisting and transportation are difficult; the leakage problem of ultra-large box is difficult to solve; the installation process requires diving operation, and the connectors at the joints are very easy to corrode. (4) Prefabricated structure connection method: It mainly adopts flange connection, pin connection, wedge connection, etc. All of the above connection forms have the main connecting load-bearing parts as metal parts, and the corrosion problem in the aquatic environment cannot be fundamentally solved. Large component connectors bear huge shear stress, and the risk of wear and discontinuity of connectors is large.
[0004] Therefore, how to effectively improve the risk resistance of large floating structures and propose a scientific and reasonable heavy-duty floating platform has become a key issue that urgently needs to be addressed in the application of floating structures. Summary of the Invention
[0005] The purpose of this invention is to provide a heavy-duty floating platform to solve the problems of inadequacy in the wharf, floating platform, and bridge pier protection facilities mentioned in the background.
[0006] To achieve the above objectives, the present invention provides a heavy-duty floating platform, comprising a plurality of working cabins arranged in a planar array. Each row and column of working cabins has a connecting cabin at both ends, and each row and column of working cabins is connected to its connecting cabins at both ends via multiple prestressing systems, thereby connecting the plurality of working cabins and connecting cabins into a single unit. The prestressing system includes prestressed clamps, prestressed anchor plates, and prestressed rigging. The prestressed clamps and prestressed anchor plates are disposed on the flange connection surfaces of the connecting cabins. The connecting cabins and the working cabins... The working chambers are all hollow boxes. The connecting chamber has multiple connecting flanges on its sidewall that contacts the working chamber. Each connecting flange includes a connecting hole on the contact sidewall and an anchoring platform located inside the contact sidewall. Multiple prestressed pipes are arranged horizontally and longitudinally inside the working chamber. The prestressed pipes penetrate the sidewall of the working chamber, and each end of the prestressed pipe forms an installation hole with the sidewall of the working chamber. Multiple prestressed shielding systems are provided between two adjacent connecting chambers and between adjacent connecting chambers and the working chamber. In this structural design, the number of prestressed shielding systems between two adjacent boxes is equal to the number of prestressed riggings installed on the contact surfaces of the two boxes. That is, each prestressed rigging has a prestressed shielding system installed between the contact surfaces of every two adjacent boxes. The floating platform is buoyed by sealed working compartments and connecting compartments. Each working compartment can provide buoyancy independently, and adjacent working compartments are connected by a prestressed system. This system prevents the entire floating platform from sinking if a single working compartment (box) is damaged and leaks. A triple shielding system consisting of sealing gaskets, sealing sleeves, and hydrophobic materials is installed within the prestressed system channels to prevent corrosion of the prestressed riggings (metal components).
[0007] Furthermore, the working chamber is equipped with four transverse prestressed ducts and four longitudinal prestressed ducts, which are staggered and independent of each other. Multiple prestressed riggings pass through the transverse and longitudinal prestressed ducts of the working chamber to connect the working chamber body.
[0008] Furthermore, the prestressed shielding system includes an annular sealing sleeve and a conical sealing sleeve; the mounting hole includes a countersunk portion for installing the annular sealing sleeve and a conical portion for installing the conical sealing sleeve, the small end of the conical portion communicating with the prestressed duct, and the large end of the conical portion communicating with the countersunk portion; a polymer material seal is provided between the connecting surfaces of the chamber to prevent water from the outside of the chamber from entering the prestressed system. The conical section (conical portion) of the prestressed duct is provided with a conical sealing sleeve that fully surrounds the prestressed rigging. After prestressing is completed, the seal deforms under pressure to achieve waterproofing; at the same time, a hydrophobic material is injected into the prestressed duct under pressure, so that when a small amount of water seeps into the duct, the grease can effectively separate the metal parts from the water.
[0009] Furthermore, adjacent working compartments and the working compartment and its contacting connecting compartment are interlocked by mortise and tenon joints; two side walls of the working compartment are provided with tenon structures, and the other two side walls of the working compartment are provided with mortise structures A adapted to the tenon structures; the side wall of the connecting compartment that contacts the working compartment is provided with mortise structures B adapted to the tenon structures. The box connection end faces are set with mortise and tenon joints to withstand the force during the box's misalignment process under service conditions, thereby eliminating the shear force of the prestressed system; the box interior is filled with energy-dissipating elements for impact energy dissipation.
[0010] Furthermore, tenon structures are provided on two adjacent side walls, or on two opposite side walls.
[0011] Furthermore, the connecting compartment is equipped with reinforcing ribs on all four sides of the sidewall that contacts the working compartment.
[0012] Furthermore, the top of the connecting compartment is provided with an inspection hole for personnel to enter the compartment to complete the connection and fastening of the connecting compartment and the working compartment, and the inspection hole is equipped with a sealing cover.
[0013] Furthermore, a prestressed anchor installation position is provided on the flange surface of the connecting cabin, and the prestressed system is tensioned in the connecting cabin to realize the connection of the floating tank on the water.
[0014] Furthermore, the working chamber is configured as a sealed box integrally cast from reinforced concrete.
[0015] Furthermore, the wall thickness of the prestressed duct is greater than the wall thickness of the working chamber.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] (1) The main working units such as the working cabin and connecting cabin of the present invention can be made of high-strength materials such as reinforced concrete and steel structure. The assembled platform can provide greater buoyancy and surface strength, thereby providing a floating box system suitable for heavy load conditions, and providing a solution for docks, large water structure platforms, bridge pier protection systems, etc.
[0018] (2) The modular arrangement of several working cabins adopted in this invention solves the problem of having connecting cabins at each connection point of the prefabricated container to a certain extent, thereby enabling the floating platform to obtain smaller disassembly units. This effectively reduces the difficulty and cost of container forming, hoisting, transportation, and installation, while also reducing the maintenance and replacement costs of the entire platform.
[0019] (3) The multi-waterproof system used in this invention provides a highly reliable connector protection system, which solves the problem of connectors of the water-based prefabricated platform being exposed to a corrosive environment.
[0020] (4) The tenon and mortise connection structure between the boxes used in this invention provides an assembled platform that relies on the strength of the box itself to bear the main force, thus solving the problem that the connecting parts of the assembled structure need to be shear resistant.
[0021] (5) The prestressed connection system in this invention, under the condition of providing sufficient prestress, has a certain degree of toughness due to the inherent toughness of the prestressed steel cable, which enables the floating box platform to have a certain degree of self-adaptability under wave load conditions, reducing the risk of damage caused by rigid collision at the junction of the box.
[0022] In addition to the objectives, features, and advantages described above, the present invention has other objectives, features, and advantages. The invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation
[0036] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.
[0037] Please see Figures 1 to 11This invention discloses a heavy-duty floating platform that can accommodate large buildings for tourism and other applications, as well as engineering equipment such as lifting facilities for engineering applications. The heavy-duty floating platform comprises several working cabins 4 arranged in a planar array. Each row and column of working cabins 4 has a connecting cabin 2 at both ends. Each row and column of working cabins 4 is connected to its two connecting cabins 2 via multiple prestressing systems 1. Prestressed anchors are installed on the flanges of the connecting cabins, and prestress is tensioned within the connecting cabins 2, thereby connecting the several working cabins 4 and the several connecting cabins 2 into a large-area, high-load-bearing heavy-duty floating platform.
[0038] For ease of explanation, Figures 1 to 4 The exploded structural diagram is used in the middle section to show the specific structure of the prestressing system 1 and the prestressing shielding system 3. The prestressing system 1 includes prestressing wedges 1.1, prestressing anchor plates 1.2, and prestressing rigging 1.3, and there are two of each of the prestressing wedges 1.1 and prestressing anchor plates 1.2. The working chamber 4 and the connecting chamber 2 are both hollow hexahedral boxes, cast in one piece with reinforced concrete, and have the function of floating in the water environment. In the working chamber 4, multiple prestressing pipes 4.1 are arranged horizontally and longitudinally. The prestressing pipes 4.1 penetrate the side wall of the working chamber 4, and each end of the prestressing pipe 4.1 forms an installation hole 4.2 with the side wall of the working chamber 4. Specifically, the prestressed duct 4.1 includes a transverse prestressed duct 4.1a and a longitudinal prestressed duct 4.1b; the working chamber 4 is equipped with four transverse prestressed ducts 4.1a and four longitudinal prestressed ducts 4.1b, which are staggered and independent of each other. Correspondingly, the connecting chamber 2 has four connecting flanges on its side wall that contacts the working chamber 4. The connecting flanges include connecting holes 2.2 on the contact side wall of the connecting chamber 2 and anchoring platforms 2.3 located inside the contact side wall, with the anchoring platforms 2.3 corresponding to the connecting holes 2.2. Prestressed rigging is used to pass through the transverse prestressed ducts 4.1a of the multiple working chambers 4 arranged in a row, connecting these working chambers to form a series box structure; prestressed rigging 1.3 is used to pass through the longitudinal prestressed ducts 4.1b of the multiple series box structures arranged side by side, connecting the series of working chambers into a planar structure. Prestressed anchor plates 1.2 and prestressed wedges 1.1 are installed sequentially on the flange connection surfaces of the two connecting chambers 2 at both ends of each prestressed rigging 1.3. The prestressed tensioning process is used to achieve an effective pre-tight connection between the working chamber 4 and the connecting chamber 2.
[0039] In one specific embodiment, the prestressing rigging 1.3 in the prestressing system 1 is made of high-strength metal, which is prone to corrosion in aquatic conditions. To prevent damage to the prestressing system, a prestressing shielding system 3 is provided between the connection surfaces of two adjacent boxes (between two adjacent working chambers 4 or between adjacent working chambers 4 and connecting chamber 2). The prestressing shielding system 3 includes an annular sealing sleeve 3.1, a conical sealing sleeve 3.2, and a hydrophobic material. The conical sealing sleeve 3.2 is a conical structure with diameters at both ends smaller than the diameter in the middle. A conical sealing structure 2.6 is provided on the connection hole 2.2 (on the contact surface side), which is used to install the conical sealing sleeve 3.2. The mounting hole 4.2 of the working chamber 4 includes a countersunk hole 4.2a and a tapered hole 4.2b. The small end of the tapered hole 4.2b is connected to the prestressed duct 4.1, and the large end of the tapered hole 4.2b is connected to the countersunk hole 4.2a. The countersunk hole 4.2a is used to install the annular sealing sleeve 3.1, and the tapered hole 4.2b is used to install the tapered sealing sleeve 3.2. During the installation of the prestressed system, a hydrophobic material is first injected into the prestressed duct under pressure. Then, an annular sealing sleeve 3.1 is pre-installed on the countersunk section of the prestressed duct. Next, the prestressed rigging 1.3 is passed through the prestressed duct, and a conical sealing sleeve 3.2 is inserted into the rigging 1.3. The conical sealing sleeve 3.2 is placed at the conical structure of the prestressed duct. Under the prestressing tension, the connecting box compresses against each other, causing the annular sealing sleeve 3.1 to deform under pressure and fit tightly against the countersunk platform of the box's annular sealing device, thus achieving the first layer of shielding. Simultaneously, the tension force of the box compresses the conical sealing sleeve 3.2, causing the inner part of the conical sleeve to be compressed and fit tightly against the prestressed rigging 1.3, while the outer part deforms under pressure and fits tightly against the conical structure of the prestressed duct, achieving the second layer of shielding. The interior of the prestressed duct is filled with a hydrophobic material, and when a small amount of water enters the duct, the hydrophobic grease isolates the rigging from the water, achieving the third layer of shielding.
[0040] In one specific embodiment, the top of the connecting compartment 2 is provided with a waist-shaped inspection hole 2.1, with dimensions of 650mm × 450mm, allowing personnel to enter the compartment to connect and secure the connecting compartment 2 to the working compartment 4; the inspection hole 2.1 is equipped with a sealing cover. Adjacent working compartments 4 and the working compartment 4 and the connecting compartment 2 in contact with it are interlocked by mortise and tenon structures; two side walls of the working compartment 4 are provided with tenon structures 4.3, and the other two side walls of the working compartment 4 are provided with mortise structures A4.4 adapted to the tenon structures 4.3; the side wall of the connecting compartment 2 in contact with the working compartment 4 is provided with mortise structures B2.4 adapted to the tenon structures 4.3. The tenon or mortise structure is integrally formed with the compartment it is attached to, and prestressing tension completes the interlocking of the mortise and tenon structures of the adjacent connecting compartments 2 and the mortise structure of the connecting compartment 2 with the tenon structure 4.3 of the working compartment 4. Tenon structures 4.3 are provided on two adjacent side walls, or on two opposite side walls. Under service conditions with water waves, the tenon and mortise structures can effectively eliminate misalignment between the boxes, thereby preventing shear failure of the prestressed system due to box misalignment. Reinforcing rib structures 2.5 are provided around the side wall of the connecting compartment 2, specifically on the side in contact with the working compartment 4, to ensure sufficient strength of the box under service conditions. It is understood that tenon structures can also be provided in the connecting compartment 2 as needed. Furthermore, by appropriately adjusting the positions of the riveting holes and tenon structures, the invention's objective can also be achieved.
[0041] In one specific implementation, the concrete thickness at the prestressed duct 4.1 is appropriately increased compared to the thickness at the working chamber 4 wall panel; this structural arrangement can better meet the connection strength requirements of the floating platform and improve the platform's load-bearing capacity.
[0042] In one specific implementation, the prestressed sling 1.3 is also replaced by a high-strength bolt or prestressed steel bar; the three-layer prestressed protective structure of the prestressed system shielding system can be increased, decreased, or slightly adjusted as needed.
[0043] The heavy-duty floating platform of this invention provides a purely prefabricated floating platform for water structures through modular structural design. In application scenarios, this invention minimizes the impact of unit boxes on the overall structure, ensuring that localized damage under operating conditions does not affect the overall structural usability.
[0044] When the heavy-duty floating platform of the present invention is arranged in a two-way planar array, it can be used as a large-scale floating work platform or a heavy-duty floating load-bearing platform; when arranged in a one-way series, it can be applied to heavy-duty load-bearing wharves or floating bridge systems; when arranged in a one-way ring series, flexible buffer material is added to the inside of the box and high energy-absorbing material is filled inside the box, making it suitable for bridge and wharf protection systems.
[0045] This invention features a well-standardized structure. It employs a modular, box-type enclosure and assembled combination structure. All enclosures can be designed and manufactured in a serialized, standardized, and modular manner according to the usage scenario. Different combinations and pairings can meet various application needs. Therefore, it has good prospects for factory-scale, mass production, and standardized manufacturing.
[0046] This invention offers good ease of construction and cost-effectiveness. The modular structure of this invention allows for relatively small individual unit sizes, simplifying the forming, transportation, and installation processes of the components, thereby reducing production costs and improving production efficiency.
[0047] This invention exhibits good durability. The invention relates to a multi-layered water shielding system and a tenon-and-mortise joint structure design for the enclosure connection, which reduces the corrosion rate of metal connectors in aquatic environments and simultaneously reduces shear stress on metal components, significantly improving the service life of the connectors.
[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
