Description

Technical Field

[0001] The invention relates to a retaining wall, in particular to a landscape ecological river retaining wall constructed by using 3D printing technology, and a construction process of the retaining wall. Background Art

[0002] In order to prevent the collapse of soil on both sides of the river and cause blockage of the river, retaining walls are generally set up on both sides of the river.

[0003] At present, the retaining walls on both sides of the river channel basically adopt gravity or arm retaining walls. Although this type of retaining wall can effectively prevent the blockage of the river channel caused by soil collapse, since this type of retaining wall is not permeable, under the protection of this type of retaining wall, the river channel is like wearing "armor", blocking the connection between river water and groundwater, and destroying the river ecosystem.

[0004] In addition, although the traditional retaining wall has a protective function, it is just a bare wall and lacks ornamental value. Summary of the invention

[0005] In view of the above problems, the present invention provides a building landscape ecological river retaining wall, which is not only permeable, but also capable of planting plants in the leaky area, and has both practical value and ornamental value.

[0006] At the same time, the present invention also provides a construction process for the architectural landscape ecological river retaining wall, which combines 3D printing construction technology with reinforced concrete structure, which not only ensures the overall structural strength of the retaining wall, but also makes the construction simple and easy to operate.

[0007] The technical solution adopted by the present invention to solve the technical problem is:

[0008] A building landscape ecological river retaining wall comprises a foundation bottom plate, wherein at least two pier walls are arranged on the foundation bottom plate, and multiple layers of connected arch walls are arranged between adjacent pier walls. The multiple layers of connected arch walls are distributed in a step-like manner from bottom to top, and there is a gap area between two adjacent layers of connected arch walls.

[0009] Furthermore, the water-facing surface of the pier wall is stepped and corresponds one-to-one with the continuous arch wall.

[0010] Furthermore, the water-facing surface of the continuous arch wall is arched.

[0011] Furthermore, the vertical portion of the water-facing surface of the pier wall is in an arc shape and is smoothly connected to the water-facing surface of the corresponding layer of the connected arch wall.

[0012] Furthermore, the back-to-water surface of the multi-arch wall is arched, and the rise-to-span ratio of the back-to-water surface is smaller than the rise-to-span ratio of the front-to-water surface of the multi-arch wall.

[0013] Furthermore, the back surface of the pier wall facing the water is a vertical plane.

[0014] Furthermore, the pier wall includes a pier wall outer formwork wall, the connected arch wall includes a connected arch wall outer formwork wall, and the pier wall outer formwork wall and the connected arch wall outer formwork wall together form a stepped outer formwork wall frame, concrete is poured in the outer formwork wall frame, and a steel mesh is arranged in each layer of the outer formwork wall frame.

[0015] Furthermore, the foundation slab comprises a foundation slab outer formwork wall, concrete is poured in the foundation slab outer formwork wall, and a steel mesh is arranged in the foundation slab outer formwork wall.

[0016] Furthermore, connecting steel bars are tied to the steel mesh, and the connecting steel bars extend into the adjacent upper concrete layer.

[0017] A construction process for a building landscape ecological river retaining wall includes the following construction steps:

[0018] First, level the land and lay the cushion layer;

[0019] Second, foundation slab construction

[0020] 2.1 Print the outer formwork wall of the foundation slab on the cushion layer using 3D printing technology;

[0021] 2.2 Set up a steel mesh inside the outer formwork wall of the foundation slab, and tie connecting steel bars on the steel mesh, with the upper end of the connecting steel bars at least 50cm higher than the upper end of the outer formwork wall of the foundation slab;

[0022] 2.3 Pour concrete inside the outer formwork wall of the foundation slab to complete the construction of the foundation slab;

[0023] Third, wall construction

[0024] 3.1 Print the first layer of outer formwork wall frame on the base plate using 3D printing technology;

[0025] 3.2 A steel mesh is installed inside the first layer of the outer formwork wall frame, and connecting steel bars are tied to the steel mesh, and the upper end of the connecting steel bars is at least 50cm higher than the upper end surface of the first layer of the outer formwork wall frame;

[0026] 3.3 Pour concrete in the first layer of outer formwork wall frame to complete the construction of the first layer of wall;

[0027] 3.4 Backfill soil on the backwater side of the first layer of wall, and the upper surface of the backfill soil is flush with the upper surface of the first layer of wall, and the compaction degree of the backfill soil is above 85%;

[0028] 3.5 Repeat steps 3.1-3.4 to complete the construction of the middle layer wall;

[0029] 3.6 Print the top outer formwork wall frame on the completed top wall using 3D printing technology;

[0030] 3.7 Set up steel mesh inside the top outer formwork wall frame;

[0031] 3.8 Pour concrete in the top-floor external formwork wall frame to complete the construction of the top-floor wall;

[0032] 3.9 Backfill soil on the backwater side of the top wall, and the upper surface of the backfill soil is flush with the upper surface of the top wall, and the compaction degree of the backfill soil is above 85%.

[0033] The beneficial effects of the present invention are:

[0034] 1. By adopting the staggered design, a leaky area is formed between adjacent arch walls, and soil is backfilled on the back of the retaining wall. In this way, on the one hand, the permeability of the retaining wall can be guaranteed, and the water system in the river channel can be connected with the groundwater system, which is conducive to the maintenance of the river channel ecosystem; on the other hand, water plants, water-drought plants and drought-tolerant plants can be planted in the leaky area between adjacent arch walls according to the water level of the river channel. By planting different kinds of plants, on the one hand, the water quality can be purified, and on the other hand, it can have an ornamental effect, making the retaining wall both practical and ornamental.

[0035] 2. By designing the retaining wall into a continuous arch structure, on the one hand, the arch structure is more beautiful and can be combined with modern beautification methods such as colored light strips to create a more beautiful visual effect; on the other hand, the arch structure can improve impact resistance and be more solid and durable.

[0036] 3. This construction process combines 3D printing construction technology with reinforced concrete structure, changing the problem that traditional buildings built with 3D printing technology alone are more beautiful than structural stability. This process not only ensures the beauty of the retaining wall, but also ensures the structural strength, stability and durability. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] like Figure 1 As shown, a building landscape ecological river retaining wall includes a foundation slab 1, and at least two pier walls are arranged on the foundation slab 1. As a specific implementation method, five pier walls are arranged on the foundation slab 1 described in this embodiment.

[0058] Multiple layers of arched walls that are recessed outward (the side away from the river channel is the outer side) are arranged between adjacent pier walls from bottom to top. As a specific implementation, four layers of arched walls are arranged between adjacent pier walls in this embodiment. For the convenience of description, the arched walls are defined as the first arched wall 22, the second arched wall 32, the third arched wall 42 and the fourth arched wall 52 from bottom to top. The four layers of arched walls are staggered in sequence along the horizontal direction (the direction of the river channel is the longitudinal direction), forming a step shape together, and as shown in FIG. Figure 2 and Figure 3 As shown in FIG. 1 , there is a gap between two adjacent layers of arch walls, and the back surface of the retaining wall is backfilled with soil. Figure 3 As shown, water in the river channel can infiltrate into the groundwater system through the leakage areas between adjacent arch walls, and different types of plants can be planted in the leakage areas between adjacent arch walls according to the water depth.

[0059] Furthermore, in order to improve the structural strength of the retaining wall, Figure 2 As shown, the water-facing surface and the back-facing surface of the arched wall are both arched, and the rise-span ratio of the back-facing surface of the arched wall is smaller than the rise-span ratio of the water-facing surface of the arched wall. Preferably, the rise-span ratio of the back-facing surface of the arched wall is 1 / 4, and the rise-span ratio of the water-facing surface of the arched wall is 1 / 3. In this way, the arched wall will form an effect of being thin in the middle and thick at both ends, which can enhance the structural strength of the arched wall on the one hand, and on the other hand, when the slope of the water-facing surface of the retaining wall is constant, the area of ​​the leaking area can be increased, the planting area can be increased, and the beautification effect can be enhanced.

The vertical part of the water-facing surface of the pier wall is in an arc shape, and the two ends of the water-facing surface of the continuous arch wall are respectively connected to the vertical part of the water-facing surface of the pier wall in a smooth transition. In this way, the pier wall and the continuous arch wall together form a wave-shaped step.

[0061] For the convenience of description, the pier wall is divided into a first-layer pier wall 21, a second-layer pier wall 31, a third-layer pier wall 41 and a fourth-layer pier wall 51 from bottom to top, and the first-layer pier wall 21 and the first-layer connected arch wall 22 form a continuous first-layer wall body 2, the second-layer pier wall 31 and the second-layer connected arch wall 32 form a continuous second-layer wall body 3, the third-layer pier wall 41 and the third-layer connected arch wall 42 form a continuous third-layer wall body 4, and the fourth-layer pier wall 51 and the fourth-layer connected arch wall 52 form a continuous fourth-layer wall body 5.
