Description

TECHNICAL FIELD

[0001] The present application belongs to the field of concrete retaining walls, and particularly relates to an ecological retaining structure based on prestressed high-strength concrete corner piles. BACKGROUND

[0002] With the acceleration of urbanization and the continuous expansion of infrastructure construction, the contradiction between slope support and ecological protection is increasingly prominent. Traditional retaining structures mostly adopt the forms of concrete gravity retaining walls, masonry retaining walls or precast pile row piles, which have certain structural stability, but generally have poor ecological performance, monotonous visual landscape, insufficient water and soil conservation capacity and other problems, forming so-called "gray barriers". In addition, the interstitial gaps of traditional precast piles are difficult to effectively close during construction, which easily leads to soil erosion, and additional filter layers or subsequent reinforcement measures need to be taken, increasing the complexity and cost of the project.

[0003] In recent years, in response to the engineering construction concept of "green, ecological and sustainable development", ecological retaining structures have gradually become a research hotspot. In the prior art, attempts are made to improve the ecological performance of the structure by means of pile body opening, net hanging and green planting, and post-filling soil planting, but there are still problems such as difficulty in balancing structural strength and ecological function, complex construction process, and insufficient long-term stability. Especially, opening in prestressed concrete piles often weakens their mechanical properties, limiting their application range.

[0004] Therefore, there is an urgent need for a new retaining structure that can achieve integrated design of ecological function and structural function under the premise of ensuring structural strength and stability, simplify the construction process, and improve the overall sustainability of the project.

The liquid guiding component is inserted into the insertion hole. The liquid guiding component is needle-shaped or closed, and has a through-flow groove inside.

[0007] According to an advantageous embodiment, it also includes a plurality of rectangular positioning plates, which are inserted together into the snap-fit ​​slots of two adjacent support piles, and through slots are provided on the rectangular positioning plates at positions corresponding to the stepped holes.

[0008] According to an advantageous embodiment, the lowermost end of the liquid guide hole is detachably provided with a sealing plug.

[0010] According to an advantageous embodiment, the rectangular through hole is selectively provided with a baffle or a sealing member, and the sealing member is provided with a through hole for inserting a reinforcing bar.

[0011] According to an advantageous embodiment, the partition is snapped into place inside the slot, and the partition and the rear step of the stepped hole together form a structure to prevent soil loss from the roots of the green plants.

[0012] According to an advantageous embodiment, the lower end of the support plate has a triangular pointed structure.

[0013] Compared with the prior art, the ecological retaining structure based on the prestressed high-strength concrete corner pile has the following beneficial effects: 1. The present application realizes seamless butt joint and closure between piles by arranging the male and female tenons and the buckling groove in the wing edge section of the high-strength concrete supporting pile, effectively controls water and soil loss, reduces the setting of the inverse filter layer, and simplifies the construction process. At the same time, the stepped hole arranged in the pile body can be used as a green planting space and a steel bar through channel, realizing the organic combination of structure reinforcement and ecological greening. Through the synergistic effect of the rectangular positioning plate, the inverted U-shaped clamping piece and the transversely arranged steel bar, the overall rigidity and stability of the retaining structure are significantly improved, overcoming the defects of insufficient strength of the traditional ecological retaining structure.

[0014] 2. The present application realizes precise drip irrigation and nutrient supply for green plants through the liquid guiding system (L-shaped plate, liquid guiding piece, liquid guiding hole, etc.), without the need for external complex equipment to maintain the environment required for plant growth, improving the sustainability of ecological function. The flexible configuration of the blocking piece and the plugging piece can select planting areas and non-planting areas according to actual needs, ensuring the beauty of the structure and avoiding soil loss.

[0025] It should be noted that the reinforcement of the support pile 1 in the application can adopt mixed reinforcement, or can adopt pure prestressed steel bar reinforcement. On the basis of the original prestressed steel bar, glass fiber reinforcement is added, and the corrosion resistance and the reinforcing performance of the glass fiber reinforcement at the wing segment can realize the opening on the centrifugally formed support pile 1 product, and ensure that the mechanical performance is not lost, without the need for other auxiliary measures, so that a very effective ecological effect is achieved, and the multifunctionality, corrosion resistance of the prefabricated pile are greatly improved, and the engineering safety and stability are improved.

[0026] Referring to Figure 2 and Figure 3 A plurality of support piles 1 are arranged to form a support structure, the male tenon 11 and the female tenon 12 of the adjacent two support piles 1 in the formed support structure are inserted in abutment, the inter-pile gap is closed, and the rectangular positioning plate 5 is inserted in the buckling slot 13 of the adjacent two support piles 1.

[0027] When the piles are arranged to form a support structure, the male tenon 11 and the female tenon 12 of the support pile 1 are arranged at both side wing segments, and the male tenon 11 and the female tenon 12 are inserted in abutment during pile sinking, so that the inter-pile gap can be effectively closed, the water and soil loss can be strictly controlled, and the process of setting up a gravel inverse filter layer on the rear side of the original prefabricated pile is reduced; meanwhile, the rectangular positioning plate 5 is inserted at the abutment position of the male tenon 11 and the female tenon 12, so that the adjacent two support piles 1 are clamped together as a whole, the support strength of the support structure is improved, and the abutment joint position of the male tenon 11 and the female tenon 12 is further compressed by the rectangular positioning plate 5, so that the tightness of the abutment joint is improved.
