Description

Technical Field

[0001] The utility model relates to the technical field of bank protection, in particular to an assembled prestressed concrete ecological supporting retaining wall. Background Art

[0002] Under the macro background of accelerating urbanization, infrastructure construction is booming. As a common supporting structure widely used in roads, bridges, water conservancy and other engineering fields, retaining walls are increasingly being used. However, traditional retaining walls have exposed many problems in practical applications, such as large footprint, high construction difficulty, and poor ecological and environmental protection effects. In order to effectively solve these problems, prestressed concrete ecological support retaining walls came into being.

[0003] With the continuous increase of urban population and the gradual expansion of urban scale, the demand for infrastructure continues to grow, and the application scenarios of retaining walls are becoming more and more diverse. Traditional retaining walls often cause a certain degree of damage to the ecological environment during the construction process, such as destroying vegetation and affecting soil stability. Therefore, the market urgently needs a new type of retaining wall that can not only meet the support requirements but also effectively protect the environment. The continuous development and innovation of prestressed concrete technology has provided solid technical support for the birth of prestressed concrete ecological support retaining walls.

[0004] By reasonably arranging prestressed steel bars inside the retaining wall, the bearing capacity and stability of the retaining wall can be significantly improved. At the same time, by arranging ecological slope protection structures on the surface of the retaining wall, such as vegetation concrete, ecological bags, etc., the ecological and environmental protection functions of the retaining wall can be realized, and the impact on the surrounding ecological environment can be effectively reduced. In addition, the use of new concrete materials and steel bar materials can further improve the performance and durability of the retaining wall, ensure its safety and reliability during long-term use, and optimize the structural design of the retaining wall to improve the economy and practicality of the retaining wall, reduce the cost of engineering construction, and improve engineering benefits.

[0005] The existing prefabricated prestressed concrete ecological support retaining wall is generally improved to address the technical problem that the existing retaining wall structure cannot meet the construction needs in soft soil areas, and there will be a technical problem that the foundation reliability is reduced and the uneven settlement of the foundation causes the retaining wall to slide. For example, the authorized Chinese patent CN219315623U discloses an assembled prestressed concrete ecological support retaining wall, which can be improved by a cantilever support structure, a first plain concrete cushion layer, a second plain concrete cushion layer, a vegetation slope protection, a guardrail, a hydrophilic trail, a precast block, a first backfill area, a vertical arm, a heel plate, a toe plate, and a retaining platform. , fish nest block retaining wall, vegetation block retaining wall, holes, mortar stone layer, gabion stone cage layer, capping stone, second backfill area, drainage components, support components, double-layer inverted filter geotextile layer, reinforced concrete base plate, plain concrete cushion layer, crushed stone cushion layer, retaining edge, drain pipe, coarse-grained filter material, filter bag geotextile, reinforced concrete support beam, block stone slab and other structures are used in combination to achieve the use of planted plants in the river channel to provide reliable support for the river channel by retaining wall, forming a landscape structure and increasing the beauty. It is particularly suitable for situations where the requirements of high and steep slope support of the river channel and the requirements of ecological and landscape shoreline creation need to be met at the same time.

[0006] However, the prefabricated prestressed concrete ecological support retaining wall in the above-mentioned cited documents has many limitations when used. These problems seriously affect its applicability and effect in different engineering environments. First, the existing prestressed concrete ecological support retaining wall lacks flexibility in design and cannot be effectively adjusted according to the retaining depth and soil pressure. This is determined by the characteristics of its structure and materials. When the retaining depth is shallow or the soil pressure is small, the retaining wall may be too strong, resulting in waste of resources. When the retaining depth is large or the soil pressure is large, the retaining wall may not provide sufficient support, thereby affecting its stability and safety. Secondly, the existing prestressed concrete ecological support retaining wall also has limitations on length setting and cannot be flexibly adjusted according to specific retaining requirements. In some special engineering environments, it is necessary to determine the length of the retaining wall based on factors such as terrain, landform and retaining requirements. However, the existing retaining walls often cannot meet these personalized needs, resulting in great limitations in practical applications.

[0007] In summary, the existing prestressed concrete ecological support retaining walls have many problems in design, production and construction, which seriously affect their applicability and effectiveness in different engineering environments. Therefore, it is necessary to improve and innovate the existing prestressed concrete ecological support retaining walls to improve their performance and applicability and meet the needs of different engineering environments.

[0029] Through the coordination of the lifting holes 2, wing edge ecological retaining wall panels 3, male tenons 4, female tenons 5, plant planting ecological chambers 6, aquatic animal ecological chambers 7, plant planting holes 8, aquatic animal entry and exit holes 9, filter water permeation holes 10, filter water exchange holes 11, and soil-stopping water permeable filter layers 12 on the prestressed retaining wall columns 1, it can be composed of a middle raised prestressed retaining wall column and the left and right wing edge retaining wall panels connected thereto and the female and male tenons arranged on the sides of the wing edge retaining wall panels; the prestressed retaining wall columns serve as support force carriers, the wing edge retaining wall panels are effective retaining parts, and the female and male tenons enable the two adjacent prestressed concrete ecological support retaining walls to be interlocked and connected; plant planting ecological chambers and aquatic animal habitat ecological chambers are arranged on the wing edge retaining wall panels; the prestressed concrete ecological support retaining wall can not only meet the requirements of bank protection and support, but also create a landscape river channel and provide a place for aquatic animals to reproduce and thrive, thus truly achieving concrete ecological support.

[0030] The core component of the retaining wall is the prestressed support retaining wall column 1, which is prefabricated with high-strength concrete. The raised design in the middle not only increases the stability of the structure, but also provides convenience for subsequent assembly. On both sides of the prestressed support retaining wall column 1, the wing-side ecological retaining wall panels 3 are fixed by reliable connection methods. These retaining wall panels not only play a supporting role, but also provide space for the creation of an ecological environment. In order to achieve rapid assembly and precise positioning, a male tenon 4 is cleverly designed on one of the wing-side ecological retaining wall panels 3, while a female tenon 5 is correspondingly provided on the other wing-side ecological retaining wall panel 3. During the assembly process, the male tenon 4 can fit tightly into the female tenon 5, ensuring the integrity and stability of the retaining wall. In order to facilitate construction and transportation, the prestressed support retaining wall column 1 is also provided with lifting holes 2. Through these lifting holes 2, the retaining wall column can be easily lifted and installed in place using equipment such as a crane. The plant planting ecological chamber 6 and the aquatic animal ecological chamber 7 on the wing-side ecological retaining wall panel 3 are a major feature of the retaining wall. The chamber 6 is located at the upper part of the retaining wall. By opening plant planting holes 8, various plants suitable for the local environment can be planted. These plants can not only beautify the environment, but also play a role in consolidating soil and protecting slopes. The aquatic animal ecological chamber 7 is located below the plant planting ecological chamber 6. By opening aquatic animal entry and exit holes 9, a place for aquatic animals to live and reproduce can be provided. At the same time, the activities of aquatic animals can also promote the circulation and purification of water bodies and improve water quality. In order to ensure the growth environment of plants and aquatic animals, the plant planting ecological chamber 6 is also provided with anti-filtration water permeable holes 10, and the aquatic animal ecological chamber 7 is provided with anti-filtration water exchange holes 11. These holes are fixedly installed with soil-stopping and water-permeable anti-filtration layers 12, which can effectively prevent soil loss and ensure the exchange and circulation of water bodies. In summary, this assembled prestressed concrete ecological support retaining wall has the advantages of stable structure, convenient construction, and ecological environmental protection. It can not only provide reliable support for the project, but also create a beautiful ecological environment and realize the harmonious coexistence of man and nature.

[0031] It should be noted that the upper and lower ends of the prestressed support retaining wall column 1 are respectively provided with lifting holes 2. The upper and lower ends of the prestressed support retaining wall column 1 are specially provided with lifting holes 2. The existence of these lifting holes 2 makes it possible to use equipment such as cranes to easily and conveniently lift the retaining wall column during the construction process, and accurately install it in the predetermined position. This design greatly improves the construction efficiency and reduces the consumption of manpower and time. At the same time, since the position of the lifting holes 2 has been carefully designed, the balance and stability of the retaining wall column during the lifting and installation process are ensured, and the safety and quality of the construction are further guaranteed. When cooperating with other structures, the role of the lifting holes 2 is more prominent. For example, in the connection with the wing edge ecological retaining wall panel 3, the prestressed support retaining wall column 1 is accurately placed at the predetermined position by a crane, and then the wing edge ecological retaining wall panel 3 is tightly connected to the retaining wall column using connecting parts to form a stable whole.

[0032] It can be understood that the upper and lower ends of the prestressed support retaining wall column 1 are provided with interconnected lifting holes 2. The upper and lower ends of the prestressed support retaining wall column 1 are carefully provided with interconnected lifting holes 2. This design brings great convenience to the construction. In actual applications, through these lifting holes 2, the retaining wall column can be easily lifted by equipment such as a crane and accurately installed in the designated position. For example, in the connection with the wing edge ecological retaining wall panel 3, the prestressed support retaining wall column 1 is lifted by a crane and placed in a predetermined position, and then the wing edge ecological retaining wall panel 3 is tightly connected to the retaining wall column using connecting parts to form a stable whole.

[0033] In addition, the shapes and sizes of the male tenon 4 and the female tenon 5 are adapted to each other, and the two can fit perfectly. This mutually adapted design allows them to fit closely when combined to form a stable connection. In actual applications, after all structures are matched with each other, the adaptability of the male tenon 4 and the female tenon 5 is crucial. Their shapes and sizes must be precisely matched to ensure the firmness and stability of the connection. This adaptability can not only provide a reliable connection, but also reduce the risk of looseness and wear, and extend the service life of the structure. In addition, the mutually adapted male tenon 4 and female tenon 5 can also provide better mechanical properties. They can evenly distribute the load and reduce stress concentration, thereby improving the overall strength and stiffness of the structure. This is especially important for structures that bear heavy loads or complex mechanical environments. In short, the mutual adaptation of the shapes and sizes of the male tenon 4 and the female tenon 5 is the key to achieving reliable connection and good mechanical properties. During the design and manufacturing process, their shapes and sizes must be strictly controlled to ensure that all structures can cooperate with each other and perform at their best.

[0034] In this embodiment, the engagement of the male tenon 4 and the female tenon 5 forms a supporting member. In actual applications, after all structures cooperate with each other, the engagement of the male tenon 4 and the female tenon 5 plays a vital role. Their close combination not only provides a strong supporting force, but also can effectively disperse and withstand external pressure, ensuring the stability and reliability of the supporting member. The design of this engagement structure has many advantages. First, it can increase the overall strength and rigidity of the supporting member, so that it can withstand a larger load. Secondly, the engagement structure can effectively prevent the relative displacement between the members, thereby improving the integrity and stability of the support system. In addition, the engagement of the male tenon 4 and the female tenon 5 can also reduce the gap between the members, prevent the intrusion of external substances such as dust and moisture, and extend the service life of the supporting member. In short, the engagement of the male tenon 4 and the female tenon 5 forms a solid supporting member. This structure is of great significance in practical applications. It can provide a strong supporting force, ensure the stability and reliability of the support system, and at the same time extend the service life of the supporting member.
