Description

Technical Field

[0001] This utility model belongs to the field of bridge pile foundation anti-corrosion technology, and specifically relates to a fiberglass cladding structure for bridge pile foundations. Background Technology

[0002] Bridge pile foundations are critical infrastructure in bridge construction, and their corrosion resistance and fatigue resistance are essential to the overall safety and service life of the bridge. Traditional pile foundation protection methods, such as concrete encapsulation or metal shells, suffer from problems such as complex construction, high cost, and susceptibility to environmental impacts during long-term use. In recent years, fiberglass reinforced plastic (FRP) materials have gradually become an ideal alternative material due to their advantages such as lightweight, high strength, corrosion resistance, and UV resistance.

[0003] However, existing bridge pile foundation fiberglass cladding structures are mostly monolithic structures, which are difficult to construct, inconvenient to transport, and have insufficient adaptability to the environment. In harsh environments such as high salt spray and high humidity, traditional fiberglass materials still have certain durability problems. Summary of the Invention

[0004] This utility model provides a fiberglass cladding structure for bridge pile foundations, which can solve the problems pointed out in the background art.

[0005] A fiberglass cladding structure for bridge pile foundations includes, from the outside to the inside, an outer shell, a sealing filling layer, and an anti-corrosion buffer layer. The outer shell is formed by connecting and enclosing several arc-shaped shells in sequence, and an adaptive adjustment restraint ring is arrayed along the length direction on the outer side of the outer shell.

[0006] Preferably, the outer shell is made of fiberglass.

[0007] Preferably, the fiberglass shell is made of FRP material.

[0008] Preferably, adjacent arc-shaped shells are connected by a number of riveting fastener assemblies.

[0009] Preferably, the adaptive adjustment restraint ring is an elastic adaptive adjustment restraint ring.

[0010] Preferably, the elastic adaptive adjustment restraint ring is an elastic rubber restraint ring.

[0011] Preferably, the sealing filler layer is a polyurethane foam layer.

[0012] Preferably, the anti-corrosion buffer layer includes an inner anti-corrosion paste layer and an outer anti-corrosion rubber layer.

[0013] Preferably, the outer shell has an array of anti-corrosion reinforcing rings along its length, and the array of anti-corrosion reinforcing rings is connected in multiple segments and fixed by bolt assemblies.

[0014] Preferably, the corrosion-resistant reinforcing ring is a polyethylene corrosion-resistant reinforcing ring.

[0015] Beneficial effects: This utility model provides a fiberglass cladding structure for bridge pile foundations. By connecting segmented arc-shaped shells, the construction process is simplified and the adaptability and stability of the structure are improved. By optimizing the structural composition, the corrosion resistance and service life of bridge pile foundations can be effectively improved, making it particularly suitable for use in harsh environmental conditions.

Detailed Implementation

[0017] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0018] Example: Figure 1-4 As shown in the figure, the fiberglass cladding structure for bridge pile foundation provided by this utility model includes, from the outside to the inside, an outer shell 1, a sealing filling layer 2, and an anti-corrosion buffer layer 3. The outer shell 1 is formed by connecting and enclosing several arc-shaped shells 11 in sequence, and the outer side of the outer shell 1 has an array of adaptive adjustment restraint rings 4 along the length direction.

[0019] Specifically, the outer shell 1 is made of fiberglass, preferably FRP (fiberglass reinforced plastic). The material can be a mixed fiber reinforced woven fabric, which combines glass fiber with carbon fiber and basalt fiber to improve tensile strength and fatigue resistance, making it suitable for high salt spray and high humidity environments. Simultaneously, a vacuum injection molding process is used, resulting in a smooth and flat outer surface that reduces the adhesion of microorganisms in the water, preventing damage to the shell structure. A nano-titanium dioxide coating is applied to the outer layer to delay UV aging and extend service life. The inner surface is relatively rough; this roughened inner wall enhances the adhesion of the inner surface of the shell, preventing slippage.

[0020] Specifically, adjacent arc-shaped shells 11 are connected by several riveting fasteners 12. Several arc-shaped shells 11 are connected in sequence and then connected by riveting fasteners 12 to facilitate transportation and quick installation, solving the problem of difficult construction of traditional integral wrapping. The riveting fasteners 12 have stepped overlapping edges on both sides, and riveting connection holes are reserved on the overlapping edges. The overlapping edges can be covered with an anti-corrosion rubber layer to increase friction, ensure sealing, and also relieve energy absorption.

[0021] Specifically, the adaptive adjustment restraint ring 4 is an elastic adaptive adjustment restraint ring, which can be an elastic rubber restraint ring to adapt to the deformation caused by pile settlement or temperature changes, and to avoid the bridge deformation leading to cracking of the cladding layer.

[0022] Specifically, the sealing filling layer 2 is a polyurethane foam layer, which is used for filling and further bonding and supporting the outer shell 1.

[0023] Specifically, the anti-corrosion buffer layer 3 includes an inner anti-corrosion paste layer and an outer anti-corrosion rubber layer. The anti-corrosion paste layer has the function of preventing corrosion, and the anti-corrosion rubber layer plays a role in mitigating energy absorption.

[0024] Specifically, the outer shell 1 has an array of anti-corrosion reinforcing rings 5 ​​along its length. The array of anti-corrosion reinforcing rings 5 ​​is connected in multiple segments and fixed by bolt assembly 51. The anti-corrosion reinforcing rings 5 ​​are polyethylene anti-corrosion reinforcing rings.

[0025] The installation method of this utility model is as follows: First, the anti-corrosion paste layer is evenly applied to the surface of the bridge pile foundation 6. Then, the anti-corrosion rubber layer is wrapped and fixed. Subsequently, the arc-shaped shells 11 are installed in sections from the bottom of the bridge pile foundation 6 upwards. After the installation of one section of the arc-shaped shell 11 is completed, polyurethane foam material is injected into the reserved space, so that the foam fills half of the shell. Then, all the arc-shaped shells 11 are installed upwards repeatedly, and the polyurethane foam material completely fills the entire reserved space. Finally, the anti-corrosion reinforcement rings 5 ​​are installed in sections.

[0026] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
