位于上海中心城区东北部的新江湾城社区有着极佳的自然地理环境，植被丰茂，水体环绕，改造的对象就是位于新江湾城社区邻里中心旁的两座便民步行桥。

Located in the northeast of the Shanghai central urban area, New Jiangwan Neighborhood has its excellent natural geographical environment with lush forests and surrounding rivers. The two pedestrian bridges for reconstruction are located next to the neighborhood center of New Jiangwan Neighborhood.

▼满船清梦压星河

设计以一叶扁舟为概念，改造后的便民桥犹如一只小船飘荡在河面，让人联想起“满船清梦压星河”的浪漫诗句。

The bridge is like a leaf floating on the river, as the romantic poem saying "Tiny boat is full of dreams and stars”.

▼顶视

原始的桥梁设计已解决功能性使用需求，但因为裸露的市政水管从桥体两侧穿过，捆绑着桥身，因此业主想以最小的代价包裹水管，提升视觉形象，同时还需灵活拆卸，方便检修。设计面临的最大挑战可能还是来自于造价，单座桥体十多万的总预算决定了“每一分钱都得花在刀刃上”。

The original bridge has already met the functional requirements. However, the exposed municipal water pipes affect the beauty. The design needs to hide the water pipes for local image at the minimum cost, and also be flexible disassemble and facilitate maintenance. The biggest challenge for design is the cost. The budget of about 100 thousand yuan for one single bridge requires.

▼改造前

留

Remain

设计首先拆除了和景观水面互动性不佳的原始栏杆，几乎没有犹豫，桥面的铺装被保留了下来。因为便民桥虽小，但 3.9 米宽、28 米长的体量也有将近 110㎡的桥面铺装面积，即使用性价比最高的材料，也会花掉近 20%的预算。除了新替换的栏杆和包裹水管的装饰构件，我们留意到周边居民对桥体夜间照明的真实而迫切的需求，设计将原本有限的预算也预留一部分在夜间照明上。

The original railings are removed and the pavements are retained. Although the convenient bridge is small, its 3.9-meter wide and 28-meter long volume also has a deck area of nearly 110 square meters. Even if we use the material with highest cost performance, the pavements will also cost nearly 20% of budget.In addition to new railings and decorative components, we also reserve part of the limited budget for night lighting, for the real and urgent demand by people in this neighborhood.

包裹水管的外观形式需和谐融入场地周边的自然环境又方便拆卸检修，木格栅顺理成章的成为了第一候选。

The decorative components need to be harmonious with the natural environment and convenient for disassembly and maintenance. The wooden grid naturally becomes our first choice.

▼改造整体策略

设计以两条柔和的曲线控制桥身线条，中间高而宽、两端低而窄，勾勒出修长而富有张力的体量，像水鸟起飞时张开的翅膀，充满瞬时的美。而底部向下、向内侧收缩的趋势也很好的削弱了因为包裹水管而带来的厚重感，使得桥体在每个不同的视角下都充满变化。

The design uses soft curves to control, the middle is high and wide, and the ends are low and narrow. It outlines a slender and tensile volume, like the wings of a water bird when it takes off,full of instantaneous beauty. The downward and inward contraction of the bottom also greatly weakens the sense of heaviness caused by the wrapped water pipe, making the bridge body full of changes in every different perspective.

▼融入野趣环境

木格栅以单一自然材料的模数化阵列实现变化的造型，格栅之间的间隙既节约了材料，也使得桥身在近看时拥有细腻的肌理变化。每当下雨的时候，雨水从格栅中穿过流向河面，桥身仿佛穿上了一层朦胧的“雨纱”。被木格栅包裹的水管实现了日常中视觉上的消失，但在需要检修时又可以方便上人并快速查找定位。

The modular array is used to realize the changing shape of the wooden grid. The gap between the grids not only reduce the cost, but also brings delicate texture change. When it rains, the rainflows through the wooden grid to the river, and the bridge body seems to wear a layer of rain gauze. The water pipes wrapped by the wooden grid disappear in daily life. However, they are easy to find during maintenance.

▼桥的细节

▼节点

栏杆设计选择了向内倾斜的双夹片扁钢形式，超薄的单片扁钢实现了在景观视野上最小化的构件可视面，双夹片的构造既增加了组合强度，又在底部集合了泛光照明灯具，一举两得。夹片之间的柔性金属网最大程度减小了材料本身对视线的遮挡，远处的自然和近处的木格栅渐次而来，使人在不觉中忘记了这道银色的阻隔。

The railings are designed in the form of double-clip flat steel, which is inclined inwards. The ultrathin single-clip flat steel achieves the minimum visible surface of the components in the landscape view. The double-clip structure not only increases the combination strength, but also integrates the floodlighting lamps at the bottom, killing two birds with one stone. The flexible metal mesh between the clips minimizes the obstruction of the material itself to the sight. The nature in the distance and the wooden grid in the near gradually come to us, making people forget the silver barrier unconsciously.

这一系列的细节设计使得便民桥除了整体飘逸的造型之外，还有精致挺拔的构造细节，代表自然的木头和代表科技的金属在此碰撞，又一同融入周边野趣的自然。

The series of detail design makes the convenient bridge not only elegant in shape, but also exquisite in detail. The wood representing nature and the metal representing technology collide here, and merge into the surrounding wild nature together.
