Description

Technical Field

[0001] This application belongs to the field of sheet pile construction technology, specifically relating to an ecological composite sheet pile structure and construction method. Background Technology

[0002] In the field of construction engineering, sheet piles play a crucial role in everything from foundation pit excavation to riverbank protection construction, ensuring construction safety and preventing soil collapse. Traditional sheet piles, such as steel sheet piles and concrete sheet piles, mostly focus on mechanical properties to meet the engineering requirements for support strength and stability. However, with increasing emphasis on the ecological environment, the shortcomings of traditional sheet piles in terms of environmental protection are becoming increasingly apparent.

[0003] In recent years, fiber-reinforced polymer (FRP) sheet piles have been increasingly used in engineering due to their lightweight, high strength, and corrosion resistance. However, conventional FRP sheet piles still primarily serve a single structural function, lacking consideration for ecological functions. While there have been attempts to improve the ecological environment through methods such as vegetation slope protection and artificial reefs in ecological restoration technology, a mature solution that organically integrates these methods with the support structure has yet to be developed. Therefore, developing a new type of sheet pile structure that balances support strength and ecological restoration functions, meeting engineering safety requirements while reducing damage to the ecological environment and alleviating seepage pressure, has become a pressing technical challenge in the field of coastal and river management engineering. Summary of the Invention

[0004] This application provides an ecological composite support sheet pile structure and construction method. Combining structural mechanics and ecological restoration requirements, it achieves the unity of "structural bearing" and "ecological restoration" functions by setting regularly distributed ecological holes in the main body of the sheet pile and embedding permeable materials or planting substrates, thereby reducing the negative impact of traditional sheet piles on the tidal flat ecology and enhancing the sustainability of the project.

[0005] To achieve the above-mentioned objectives, this application provides the following technical solution:

[0006] This application provides an ecological composite sheet pile support structure, which includes:

[0007] A fiberboard assembly comprising multiple fiberboards joined together in sequence, wherein a limiting groove is provided on the upper part of the fiberboards and a flower basket is provided at the limiting groove;

[0008] A front support assembly includes multiple front support units, each front support unit including a support rod, one end of which is provided with a bracket and the other end is movably provided with a support leg, and the two ends of the bracket are respectively movably provided with a left positioning block and a right positioning block that are adapted to the two sides of the limiting groove;

[0009] The rear support assembly includes a horizontal plate and a plurality of wooden stakes evenly inserted into the horizontal plate;

[0010] Wherein: the horizontal plate of the rear support assembly abuts against and supports the rear side of each fiberboard of the fiberboard assembly, and each front support unit abuts against and supports the limiting groove of each fiberboard through the left positioning block and the right positioning block.

[0011] Furthermore, the fiberboard has a trapezoidal cross-section with an opening at the front, and matching protrusions and grooves are provided on both sides. The limiting groove has the bottom of the trapezoidal structure, and adjacent fiberboards are spliced ​​together through the protrusions and grooves.

[0012] Furthermore, the fiberboard has a micro-channel inside the limiting groove, a bird's nest is provided above the micro-channel, the flower basket is located at the upper part of the limiting groove, and several drainage holes are provided on the front side of the flower basket.

[0013] Furthermore, a biodegradable mesh bag is provided inside the micro-channel.

[0014] Furthermore, the fiberboard is made of fiber-reinforced composite material.

[0015] Furthermore, the horizontal plate of the rear support assembly can be adjusted up and down on the wooden stake.

[0016] This application discloses a construction method for an ecological composite support sheet pile structure based on the above technical solution, the steps of which are as follows:

[0017] S1: Assemble multiple fiberboards in sequence to form a fiberboard assembly, bury the lower end of each fiberboard in the soil, fix the support rod of each front support unit on the bracket, rotate and install the left positioning block and the right positioning block at both ends of the bracket, embed the left positioning block and the right positioning block of each front support unit into the limiting groove of the corresponding fiberboard and support each fiberboard, install the other end of the support rod on the support foot, and drive the support foot into the soil;

[0018] S2. Drive each wooden stake of the rear support assembly through the horizontal plate and into the soil, and support the rear side of each fiberboard through the side of the horizontal plate.

[0019] S3. Planting substrate is placed in the flower baskets on the upper part of each fiberboard and flowers and grasses are planted.

[0020] Compared with existing technologies, this application presents an ecological composite support sheet pile structure and construction method. First, it designs FRP (fiber reinforced plastic) sheet piles with ecological pores, which are lightweight, high-strength, and corrosion-resistant. The pre-reserved pores in the pile body are filled with planting substrate, balancing support strength and ecological restoration function. Second, the horizontal plate behind the sheet pile can be adjusted up and down, making installation convenient and suitable for water surfaces of different heights. The front support unit can be adjusted 90 degrees, making installation and fixing convenient. This can effectively reduce the damage to tidal flat biological habitats caused by traditional support. The permeable pores in the fiberboard material can alleviate seepage pressure under high water levels and prevent piping. Attached Figure Description
