Appreciation towards Architecture School of Tianjin University for providing the following description:
The 2020 Chengdu Park City International Garden Festival and the third Beijing Forestry University International Garden Construction Festival has been open to the public at Chengdu Guixi Ecological Park from October 24th to November 24th. The “Picture Scroll Of Bamboo Curtain” from Tianjin University won the first prize of Chengdu Park City International Garden Festival and the third Beijing Forestry University International Garden Construction Festival in 2020.

“Picture Scroll Of Bamboo Curtainl”is a bamboo garden with a sense of rhythm and mystery, which took three and a half days to complete. The bamboo structure was all built with bamboo pieces, which perfectly shows that the bamboo pieces are not only the supporting structure, but also the skin, and the integrated form of the rhythmic space. The weaving operation maximizes the advantages of the flexibility and bending resistance of the bamboo pieces.

The theme of this garden construction is “secret garden”. The design team believed that mystery is not only a occlusion of the line of sight, but also a variety of spatial experience. The project was designed according to the concept of “bead curtain roll”, hoping that the flowers and bamboo will blend together and the curtain will be rolled up.The bamboo pieces were interwoven to form a bamboo curtain, which rotates to create a curtain roll, and the curtains were superimposed to form a picture scroll. The bamboo structure was constructed with a pure weaving form, from simple to complex, both real and virtual, and the environment melts into the bamboo, forming a “Picture Scroll of Bamboo Curtain” secret garden that is also dreamy and fantasy.

Bamboo is a structural material with high strength and toughness. Compared with wood, it has the characteristics of being extremely light and easy to bend into a curved contour. “Picture Scroll of Bamboo Curtain” always pays attention to reflecting the characteristics of bamboo and structural aesthetics. The five groups of bamboo pieces were bent, twisted, rotated and interwoven to form the basic frame, so that the originally lightweight and easily deformable soft structure can form a stable structure through mutual force. At the same time, while ensuring the original formal logic, special two-strand bamboo pieces were added to increase the intersection of bamboo pieces and the overall structure is not easy to deform. Strive to integrate the structure, skin, space, and form of the structure on the basis of conforming to the mechanics logic and aesthetic principles, while ensuring that the bamboo texture is rich in rhythm and the nodes are artfully connected. Grasshopper and Rhino were used to refine the model. After several adjustments, the final plan was determined.

In order to explore the possible problems in the on-site construction process, before construction, the Tianjin University team used bamboo pieces and other materials to pre-build the bamboo structure in the Tianjin University Water Conservancy Pavilion at a ratio of 1:1.

During the construction process, considering that there are many knitting nodes on the top part which may have a greater impact on the overall shape, the team decided to weave the top first to ensure the aesthetic appearance. In order to facilitate the erection, a suitable supporting structure was designed and removed after the basic weaving of bamboo pieces is completed. In the treatment of the bottom part , the bamboo pieces were collected on the bottom ring which was landed on the ground in a staggered manner to ensure the feasibility of construction. In the nodes connection, bamboo rings of the same specification were added between the bamboo pieces to ensure the equal spacing of each group of bamboo chips, and the structure was fixed with long screws and nuts to achieve the effect of sparse and dense rhythm.

The entire construction process includes material classification, bamboo pieces connection, main structure construction, and node fixing, etc. On the first day, the materials were sorted, the bamboo pieces were connected and the top was weaved and supported by bamboo poles. On the second day, the structure was strengthened, and the weaving of bamboo and the fixing of the nodes were carried out simultaneously. On the third day, the supporting bamboo poles were removed, and the position of the bamboo pieces was adjusted to optimize the overall appearance.

In the process of on-site construction, according to the pre-built experience, the height of bamboo structure was increased by 10%, which ensured the perfect shape effect after removing the support structure and deformation of bamboo structure. At the same time, the number of nodes at the bottom was increased to make the bamboo structure more stable. Without any round bamboo support, through the interaction between bamboo pieces, the integration of structure, skin, space and shape of the structure was truly realized, making the bamboo structure achieve the harmonious unity of softness and tenacity.

Flower border construction
The artistic conception of the garden echoes the clean and tidy form of the bamboo structure. The flower border design adopts curve form, and uses leafy plants such as Ageratum conyzoides L.、Salvia leucantha、Sedum lineare Thunb.、Liriope muscari ‘Variegata’、Rosmarinus officinalis etc. to build an artistic conception.At the entrance of the garden, colorful flowers such as Lantana camara L.、 Asclepias curassavica L.、Helianthus annuus、Calibrchoa Million Bells、Dianthus magic charms F1 Hybrid Dwarf. were used to embellish the layering and mysteriousness of the entrance. At the same time, the space was further enclosed by ornamental grasses such as Muhlenbergia capillaris (Lam.) Trin.、Miscanthussinensis ‘Adagio’，creating a mysterious space experience. When people shuttle among them, the hem of the clothes will gently swept the inflorescence, the natural wild interest will be felt. The overall height of the flower border is uneven, and the spatial sense is rich.

The ground of the garden is paved with pebbles and gravel, combined with curved round bamboos to form a natural path, which is unified with the bamboo structure, creating a secret garden that attracts people to enter and explore.
