[0002] In slope engineering, traditional cast-in-place concrete retaining walls are widely used in retaining and protective structures. However, with changing engineering needs and technological advancements, traditional cast-in-place retaining walls have gradually revealed a series of problems:
[0003] First, the construction period for cast-in-place concrete structures is relatively long and has high requirements for the construction site, which leads to greater construction difficulty, extended construction period, and thus increased project cost.
[0004] Secondly, the construction damaged the original slope ecology, and traditional retaining walls generally lack ecological design, making it difficult to restore the original ecology. Utility Model Content
[0005] In view of this, the present invention provides a prefabricated ecological permeable concrete retaining wall, which can solve the problems of long construction period, high project cost, insufficient ecological adaptability and environmental damage of traditional retaining walls.
[0006] To achieve the above objectives, the present invention provides a prefabricated ecological permeable concrete retaining wall, comprising a prefabricated base slab and prefabricated vertical slabs detachably connected to the prefabricated base slab. Anchor cables are provided on the back of the prefabricated vertical slabs, and the other end of the anchor cables is connected to an anchor plate. The anchor plate is placed in the backfill behind the retaining wall. Several prefabricated columns are detachably connected to the front of the prefabricated vertical slabs. The prefabricated columns are arranged in a horizontally spaced array along the prefabricated vertical slabs. Several ecological components are also provided on the front of the prefabricated vertical slabs and embedded in the prefabricated columns. The ecological components are arranged vertically along the prefabricated columns.
[0007] Preferably, the precast base plate is provided with a horizontal insertion groove, and the bottom of the precast vertical plate is provided with an insertion plate corresponding to the insertion groove.
[0008] Preferably, the precast column has an I-shaped cross-section and includes a first wing plate, a second wing plate, and a waist plate. The waist plate is disposed between the first wing plate and the second wing plate. The front of the precast column has a vertical embedding groove, and the first wing plate is slidably embedded into the embedding groove of the precast column.
[0009] Preferably, the lateral length of the waist plate is greater than the depth of the embedding groove, the ecological component is embedded between two adjacent precast columns, and one end of the ecological component is embedded between the second wing plate of one of the adjacent precast columns and the front of the precast slab, and the other end of the ecological component is embedded between the second wing plate of the other adjacent precast column and the front of the precast slab.
[0010] Preferably, the ecological component has a groove inside, which is used for planting green plants, filling soil, or providing a microhabitat.
[0011] Preferably, the front side of the precast slab is provided with a plurality of drainage holes penetrating the precast slab, and the drainage holes are located in the gap between two adjacent ecological components.
[0012] Preferably, the drain hole is provided with a drain pipe.
[0013] Preferably, the precast slab and precast column are provided with corresponding through holes penetrating the front and rear, and anchors are provided in the through holes, with one end of the anchor cable fixedly connected to the anchor.
[0014] Preferably, the front side of the anchor is sealed with a concrete sealing cap.
[0015] As can be seen from the above technical solution, compared with the prior art, the prefabricated ecological permeable concrete retaining wall provided by this utility model has the following beneficial effects:
[0016] (1) Improve construction efficiency
[0017] By combining factory prefabrication with on-site rapid assembly, the construction method significantly reduces complex procedures such as on-site concrete pouring and formwork erection and dismantling, thus significantly shortening the construction cycle. The modular components adopt a precise docking design, eliminating the need for complex processing and adjustments. The installation process is efficient and convenient, making it particularly suitable for urgent projects that require rapid completion (such as post-disaster repair) and the rapid advancement of large-scale projects. At the same time, the standardized construction process reduces the requirements for construction technical skills and improves the controllability and consistency of construction quality.
[0018] (2) Reduce project costs
[0019] The adoption of standardized and modular component production not only improves the production efficiency of components but also reduces the cost of personalized customization. During on-site construction, the modular design significantly reduces material loss and construction waste, reduces the use of on-site labor and heavy machinery, and significantly reduces construction costs. In addition, due to the shortened construction period, it also indirectly reduces project management costs and socio-economic losses caused by construction interference.
[0020] (3) Enhance ecological adaptability
[0021] The retaining wall design incorporates ecological components, with reserved space for greening. This space can be used for planting greenery, placing ecological substrates, or introducing microhabitats, forming a "green wall." This ecological design not only combines retaining and greening but also improves the regional microclimate and enhances the diversity of the regional ecosystem. At the same time, the wall effectively guides rainwater infiltration by setting permeable components (drainage holes and drainage pipes), reducing the erosion of the environment by surface runoff and further promoting the restoration of the regional ecosystem.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of an exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0028] Please see the appendix Figure 1-3The prefabricated ecological permeable concrete retaining wall disclosed in this utility model combines factory prefabrication with rapid on-site assembly, which not only significantly shortens the construction cycle but also reduces the special requirements for the construction site, effectively reduces construction disturbance, and lowers the overall project cost. At the same time, the retaining wall incorporates ecological concepts in its design, and improves the adaptability of the wall to the surrounding environment by rationally optimizing structural components, thus meeting the requirements of modern engineering for green environmental protection and sustainable development.
[0029] The prefabricated ecological permeable concrete retaining wall provided by this utility model includes an anchor plate 1, an anchor cable 2, a prefabricated base plate 3, a prefabricated vertical plate 4, a prefabricated column 5, an ecological component 6, a drainage hole 7, and an anchor 9.
[0030] Anchor plate 1 is installed in the backfill behind the retaining wall and connected to the retaining wall by anchor cable 2. Anchor cable 2 is composed of steel bars and serves as both horizontal bracing and horizontal tensile resistance, significantly improving the retaining wall's anti-slip capacity and structural stability. Anchor cable 2 passes through precast vertical plate 4 and precast column 5 from behind the retaining wall and connects to anchor 9 in precast column 5 to form an anchoring system that provides horizontal tensile force to the retaining wall.
[0031] The precast base slab 3 features a modular design with precisely positioned interlocking slots for mounting the precast vertical slabs 4. The design of the precast base slab 3 fully considers the load-bearing capacity of the wall and the foundation conditions. The dimensions and material thickness of the precast base slab 3 can be adjusted according to different project requirements, thus adapting to various construction environments.
[0032] The precast slab 4 serves as the main load-bearing unit of the wall, primarily functioning as a retaining wall. It is designed with an embedding groove that matches the precast column 5, providing positional guidance and support for the stable installation of the precast column 5. The precast slab 4 is equipped with multiple rows of drainage holes 7 penetrating the wall.
[0033] The precast column 5 is a modular vertical load-bearing unit with an I-shaped cross-section, including a first wing plate, a second wing plate, and a waist plate. The waist plate is located between the first and second wing plates. The first wing plate matches the embedded groove on the precast column 4, and the lateral length of the waist plate is greater than the depth of the embedded groove. The pre-installed anchors 9 in the precast column 5 can be used to connect with the anchor cables 2. After the anchor cables 2 are installed, the holes are sealed with concrete caps 10.
[0034] The ecological component 6 is shaped like a dog bone and has grooves inside for planting greenery, filling soil, or providing microhabitats to achieve a positive interaction between the wall and the natural environment. The ecological component 6 is embedded between two adjacent precast columns 5, with one end of the ecological component 6 embedded between the second wing plate of one of the adjacent precast columns 5 and the front of the precast slab 4, and the other end of the ecological component 6 embedded between the second wing plate of the other adjacent precast column 5 and the front of the precast slab 4.
[0035] Drainage holes 7 are used to install drainage pipes 8. Drainage holes 7 are pre-installed on the prefabricated vertical slab 4, in the gap between two adjacent ecological components 6, at an inclined angle to facilitate water drainage. They also provide water to the ecological components 6. Drainage pipes 8 are installed in the drainage holes 7 and are typically made of PVC.
[0036] The anchor 9 is made of steel and can fix the anchor cable 2 in the precast column 5. The cast-in-place concrete sealing cover 10 serves to seal the hole, isolate it from the outside air, and prevent rainwater and other factors from corroding the anchor 9 and other components inside the precast column 5.
[0037] The specific construction steps of the prefabricated ecological permeable concrete retaining wall disclosed in this utility model are as follows:
[0038] (1) Excavation of earthwork and leveling of the site;
[0039] (2) Lay the precast base plate 3 on the leveled foundation;
[0040] (3) Use a crane to lift the precast vertical slab 4 and fix the bottom of the precast vertical slab 4 into the insertion groove on the precast base plate 3;
[0041] (4) Hoist the precast columns 5 and install them so that the precast columns 5 correspond one-to-one with the embedded grooves on the precast slabs 4;
[0042] (5) Place the ecological component 6 in the gap between two adjacent precast columns 5, and start backfilling after installation;
[0043] (6) The earthwork backfilling method adopts a layered backfilling and compaction construction process;
[0044] (7) When the earthwork is backfilled to the design elevation, the anchor cable groove and anchor plate pit are excavated in the soil layer. The anchor plate 1 is installed in the anchor plate pit. Then, the drilling construction is started at the design position after the precast slab 4 using drilling rigs and other tools, penetrating the precast slab 4 and the precast column 5. The anchor cable 2 is inserted from the anchor cable groove into the hole and connected to the anchor 9 in the precast column 5, and anchored together with the anchor plate 1 at the other end.
[0045] (8) Continue to backfill the soil in layers and compact it to the top of the retaining wall. When the soil compaction reaches the design requirements, tension the anchor cable 2, and then fill the hole of the precast column 5 with the cast-in-place concrete sealing cap 10 to seal the hole.
[0046] (9) Insert the drainage pipe 8 obliquely into the drainage hole 7 on the precast vertical plate 4, and the construction of the retaining wall is completed.
