Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy engineering, and in particular to a combined structure of ecological piles and ecological panel walls. Background Technology

[0002] In traditional water conservancy engineering, conventional support structures often employ construction techniques such as cast-in-place concrete or masonry. These techniques suffer from problems such as long construction cycles, low work efficiency, high construction costs, and difficulty in quality control. In particular, masonry and dry-laid stone support structures are prone to interface failure between the stones and concrete under temperature stress, typically resulting in structural instability within 2-3 years, indicating insufficient durability and reliability.

[0003] Furthermore, existing sheet pile structures, such as steel sheet piles, while offering good bending resistance, are expensive and susceptible to corrosion; while traditional concrete sheet piles suffer from unstable installation and lower bending resistance. More importantly, traditional support structures create a rigid interface, isolating water exchange and ecological connections, which does not align with current green and ecological development requirements.

[0004] Therefore, there is an urgent need for a new type of support structure that combines high structural strength, convenient construction, economical cost, and the ability to promote ecological restoration. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a combination structure of ecological piles and ecological wall panels that is structurally stable, quick to construct, easy to maintain, durable and can realize ecological functions.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an ecological pile and ecological wall combination structure, including at least one prefabricated ecological pile and at least one prefabricated ecological wall; the ecological pile and the ecological wall are detachably connected by a mortise and tenon structure; the mortise and tenon structure includes a convex round part and a groove part adapted to the convex round part at the end of the ecological pile and / or the ecological wall; the ecological wall is provided with ecological holes for guiding water flow and allowing plant roots to pass through.

[0007] To be further specific, both ends of the ecological pile are provided with convex round portions, and both ends of the ecological wall panel are provided with groove portions; or, both ends of the ecological pile are provided with groove portions, and both ends of the ecological wall panel are provided with convex round portions.

[0008] To be further specified, the bottom of the ecological pile is a wedge-shaped structure to facilitate soil breaking, and the wedge-shaped structure is connected to the pile body by a transitional arc.

[0009] To be further specified, the ecological pile is a precast concrete sheet pile using the pre-tensioning method, which has a composite reinforcement structure inside. The composite reinforcement structure includes longitudinally parallel prestressed steel strands and HRB400 grade steel bars, as well as transverse stirrups, which are fixed around the prestressed steel strands and HRB400 grade steel bars.

[0010] The beneficial effects of this utility model are:

[0011] I. Modular Design and Convenience of Construction: Through the factory prefabrication of ecological piles and ecological wall panels, and the mortise and tenon joints between the convex and concave sections, rapid assembly construction of the structure is achieved. Specifically, the factory-pre-tensioned prefabrication process shortens the on-site construction cycle of traditional cast-in-place support structures from 7-10 days to completing single-pile production within 24 hours, thus significantly reducing the overall construction period. On-site assembly only requires pile driving and slab insertion, reducing the time and cost of cast-in-place operations, while also reducing construction noise and dust pollution, meeting green construction standards. The modular design allows for individual component replacement in case of localized damage, eliminating the need for complete dismantling and significantly reducing subsequent maintenance costs.

[0012] II. Superior Structural Performance and Controllable Quality: The ecological piles are prefabricated using the pre-tensioning method and incorporate a composite reinforcement system consisting of prestressed steel strands, HRB400 grade steel bars, and stirrups. This system, through the synergistic mechanical properties of the prestressed steel strands and steel bars, significantly enhances the structure's ultimate tensile bearing capacity while simultaneously strengthening flexural stiffness and crack toughness. Furthermore, the complementary mechanism of material mechanical properties optimizes section efficiency, reducing component section height by 15%-20% under the same bearing capacity conditions, effectively achieving the goal of lightweight structural design. Factory prefabrication fundamentally solves common quality problems in cast-in-place structures, such as insufficient compaction and reinforcement displacement, ensuring stable component quality and structural durability. The pre-construction of ecological piles allows for precise control of pile position and verticality, providing a stable benchmark for the insertion of the ecological slab wall, creating a collaborative force-bearing system between the piles and the slab: the piles bear vertical and horizontal loads, while the slab effectively transmits earth pressure, thus significantly improving the overall structure's resistance to deformation, making it particularly suitable for complex conditions such as soft soil foundations and high slopes.

[0013] III. Significant Ecological Benefits: The ecological holes in the ecological wall effectively drain water seepage from the soil behind the wall, reducing pore water pressure. In the construction sequence of piles before slabs, the perforated structure of the wall remains intact. This not only provides channels for water flow but also provides ample space for plant root growth and microbial attachment, enabling rapid slope greening and soil and water conservation, and contributing to biodiversity restoration. The anchoring effect of the root system further enhances soil stability, achieving an organic combination of engineering protection and ecological restoration, fundamentally breaking the problem of rigid ecological isolation caused by traditional support structures.

[0014] IV. High adaptability and economy: The wedge-shaped structure and transition arc design at the bottom of the ecological pile enable it to better adapt to complex geological conditions, facilitate construction, and avoid damage to the pile body caused by stress concentration.

[0015] In summary, this utility model combines the advantages of prefabricated components, such as stable quality, quick construction, and convenient maintenance, with the long-term benefits of ecological restoration (such as reducing the cost of soil erosion control). This results in a significantly lower overall cost over the entire life cycle compared to traditional processes, making it highly valuable for widespread application. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Example 1

[0030] See Figure 1 , Figure 4 and Figure 5 This utility model discloses a combined structure of ecological piles and ecological wall panels, comprising three ecological piles and two ecological wall panels. The ecological piles and ecological wall panels are detachably connected via mortise and tenon joints, with a connection angle of 0° between them. The ecological piles are 600-800mm long and 250-350mm thick; the ecological wall panels are 600-1000mm long and 180-250mm thick, with specific dimensions designed according to actual project conditions. The ecological piles and ecological wall panels can be freely combined, and their modular design allows for individual component replacement in case of partial damage, eliminating the need for complete dismantling and reducing subsequent maintenance costs. The mortise and tenon joints connecting the ecological piles and ecological wall panels create a self-locking effect, ensuring the continuity and integrity of the connection. This connection method requires no additional welding or bolt fixing, making construction convenient.

[0031] Ecological holes are provided in the ecological wall to guide water flow and allow plant roots to pass through. Specifically, the ecological holes in the ecological wall can guide water seepage from the soil behind the wall, reduce pore water pressure, and improve the long-term stability of the slope support; in addition, plant roots can penetrate deep into the soil through the holes, which can further anchor the slope and enhance the soil's anti-sliding ability.

[0032] The bottom of the ecological pile features a wedge-shaped structure to facilitate soil breaking, and the wedge-shaped structure is connected to the pile body by a transitional arc. Specifically, the ecological pile adopts a wedge-shaped design at the bottom, providing a certain soil-breaking structure. At the same time, the transitional arc design between the wedge-shaped bottom and the pile body avoids concrete cracking caused by stress concentration, ensuring the integrity and stability of the ecological pile under complex geological conditions.

[0033] Ecological piles are precast concrete sheet piles using the pre-tensioning method, featuring a composite reinforcement structure. This structure includes longitudinally parallel prestressed steel strands and HRB400 grade steel bars, as well as stirrups that transversely wrap around the prestressed steel strands and HRB400 grade steel bars. The diameter of the prestressed steel strands is 12.5mm-13.0mm, and the diameter of the stirrups is 7mm-9mm. The reinforcement and dimensions of the pile body can be selected according to actual needs, and are not limited to these dimensions. Ecological piles utilize a composite reinforcement design combining prestressed steel strands, HRB400 grade steel bars, and stirrups. The high-strength prestressed steel strands bear the main tensile stress of the structure, effectively improving the ultimate tensile bearing capacity of the sheet pile. The HRB400 grade steel bars optimize the stress distribution of the cross-section, enhancing the ductility and shear resistance of the structure. The stirrups, by confining the core concrete, improve the torsional and shear resistance of the sheet pile, offering significant advantages compared to traditional reinforcement structures. Ecological piles are precast sheet piles produced using the pre-tensioning method. As precast components, they avoid the problem of unstable quality in on-site casting, ensuring the quality of sheet pile construction, reducing later maintenance costs, and significantly shortening the construction cycle.

[0034] Among them, the ecological pile is A pile 1, with convex rounded ends, and the ecological wall is B wall 4, with grooved ends. The convex rounded ends of A pile 1 are matched with the grooved ends of B wall 4.

[0035] During construction, the prefabricated pile A1 is first driven into the soil at the designed position and angle to form a support frame; then the groove of the prefabricated B-plate wall 4 is aligned with the convex part of the already positioned pile A1 and inserted, thereby quickly assembling a complete pile-plate wall support system.

[0039] During construction, the prefabricated B piles 2 are first driven into the soil at the designed position and angle to form a support frame; then the convex part of the prefabricated A plate wall 3 is aligned with the groove of the B pile 2 and inserted, thereby quickly assembling a complete pile-plate wall support system.
