Description

Technical Field

[0001] The invention belongs to the field of water conservancy projects and bridge protection, and in particular relates to a multi-layer protection frame anti-tidal surge scouring device and a construction method. Background Art

[0002] Scour protection for structures such as bridge piers has always been a key technical issue in the fields of hydraulic engineering and bridge protection. Long-term scouring of bridge piers by water can lead to erosion of their foundations, compromising their stability and safety. Scour is particularly severe in areas with fast-flowing rivers and variable currents, potentially causing localized damage or even complete instability, severely impacting the lifespan and operational safety of the bridge.

[0003] Traditional scour protection measures typically employ concrete slope protection, riprap, or reinforced concrete structures. However, these methods have several drawbacks. For example, concrete slope protection and riprap are prone to displacement or damage under scour, requiring frequent maintenance. While reinforced concrete structures offer good scour resistance, their construction is complex and costly, and they can still sustain some damage under high-velocity water flows.

[0004] Furthermore, some existing scour protection devices lack design flexibility, making them difficult to adapt to varying pier sizes and flow conditions. During construction, these devices are difficult to install and remove, increasing both construction difficulty and maintenance costs. Therefore, there is an urgent need for a new scour protection device and construction method that effectively resists scour, is highly adaptable, convenient to install, and cost-effective, to enhance the protective performance and durability of structures such as piers.

[0022] The beneficial effects of the present invention are:

[0023] 1) Through the multi-level diversion ring design, the present invention effectively guides the water flow to the upper and lower sides for diversion, changing the direction and speed of the water flow; the setting of the V-shaped diversion plate causes the water flow to form vortices in a specific area. This process can consume a large amount of kinetic energy of the water flow, significantly reducing the scouring energy of the water flow on structures such as bridge piers; at the same time, the arc structure of the ear-shaped diversion connector further reduces the water flow velocity, realizes multi-level energy dissipation, effectively protects the bridge piers from the strong impact of the water flow, and extends the service life of the structure.

[0024] 2) The structural design of the hollow first diverter ring and the hollow diverter fixing ring of the present invention enables the device to maintain a stable fixed state under the action of water scouring; the close fit between the inner arc-shaped fixing lock and the ear-shaped diverter connector, as well as the mutual fit between the groove and the protrusion, ensure the firm connection between the components; this stable structural design effectively prevents the device from loosening or shifting due to water scouring, thereby enhancing the anti-scouring performance of the entire anti-scouring device and providing reliable protection for important structures such as bridge piers.

[0025] 3) The present invention adopts a detachable design concept, including a first diversion anti-scour ring, a diversion fixing ring and other components; this design makes the installation and disassembly process of the device extremely convenient. During the construction process, it can be flexibly assembled and adjusted according to the specific size of the pier and site conditions. When the device needs maintenance or replacement of parts, it can also be quickly disassembled and replaced, which greatly improves construction efficiency, reduces maintenance costs, and also reduces the impact on the normal operation of the bridge.

[0026] 4) The multi-level adjustable protective frame structure of the present invention can be flexibly adjusted according to different bridge pier sizes and water flow conditions; by changing parameters such as the spacing of the diverter rings on each layer, the height of the ear-type diverter connectors and the V-type diverter plates, it can adapt to bridge piers of different sizes and water flow environments with different flow rates and flow rates. This good adaptability enables the device to be widely used in various bridge projects, whether it is a large bridge or a small bridge, whether it is a river with turbulent water flow or an area with relatively gentle water flow, it can play an excellent anti-scouring role and has a wide range of applications.

[0027] 5) The present invention ensures the accuracy of the device during installation by precisely designing the vertical bayonet rails, adjustable anti-friction fixing devices, and the sizes and positions of the diverter rings on each layer. This high-precision construction method helps to improve the quality of the entire anti-scour device, enabling it to better perform its designed functions. At the same time, standardized prefabricated components and assembly construction processes reduce errors and uncertainties in on-site construction, further ensuring construction quality and device reliability.
