Lab D+H：砂厂处于郑州老城核心区，它曾经是亚洲最大的砂轮厂，为全国各地输送“重工业牙齿”砂轮磨具，也是中国一五计划时期东德援建的重要项目。其具有先锋风格包豪斯特征的厂房建筑结构体系，当年是在德国生产、中国组装，体现着“超豪华”的建设规格，也承载着中德友谊以及新中国的工业梦想。但随着城市发展与工业类型的变革，厂区生产任务的外迁，已完全空置化，成为中国国家级历史保护建筑。
Lab D+H: The 2nd Grinding Wheel Plant locates in the core area of the old city of Zhengzhou. It was once the largest grinding wheel factory in Asia, delivering grinding wheels and abrasive tools, “heavy industry teeth,” to all parts of the country. It is also an important project aided by East Germany during China’s First Five-Year Plan. At that time, the factory building structure system with the characteristics of the avant-garde Bauhaus was produced in Germany and assembled in China, reflecting the “super luxurious” construction specifications and carrying the Sino-German friendship and the industrial dream of the new China. However, with the change of urban development and industrial types, the relocation of production tasks in the factory area has been entirely vacant. It has become a National Historic Preservation Building.
本次景观设计理念是“开放融合与多元重生”，对这座工业遗址改造的文创园公共空间进行梳理，通过历史文脉研究，保留场地内的工业器械、以现代的设计手法合理利用，将工业记忆转化为不同类型的公共活动场所。我们希望框架性的景观系统能够让二砂厂以新的姿态重新融入城市文化之中，面向各种类型的人群开放。郑州二砂厂文创园建成后成为郑州老城区核心的城市活力新地标，提升了原本萧条的旧工业区的公共空间品质，同时建立更为积极的周边社区关系。
Transform industrial memory into different types of public activity spaces. The concept of landscape design is “open integration and diverse rebirth.” The public space of the cultural and creative park transformed from this industrial site is sorted out. Through the study of historical context, the industrial equipment in the area is preserved, and the modern design methods are used rationally. We hope that the framed landscape system will allow the 2nd Grinding Wheel Plant to reintegrate into the urban culture with a new attitude, welcoming various types of people. After the completion of Zhengzhou 2nd Grinding Wheel Plant Cultural and Creative Park, it has become a new landmark of urban vitality in the core of the old city of Zhengzhou. It improves the quality of public space in the originally depressed old industrial zone and establishes a more positive relationship with surrounding communities at the same time.

现状分析 SITE ANALYSIS
新中国成立初期工业基础薄弱，在苏联派遣援建的东德工程师帮助下，中国建设了全国最大的砂轮厂——郑州二砂厂。厂房具有典型的包豪斯建筑风格特征，也成为了当时郑州的重要支柱产业，是每个郑州人心中的时代记忆。在这亚洲最大的包豪斯建筑群中，混凝土板制的老式苏联建筑占据主导，建筑之间巨大雪松和梧桐生长繁茂，错综复杂的管道系统，无处不在的砂轮模具，废弃的工业生产工具，厚重的历史气息，深刻的工业痕迹，强烈的视觉冲击让我们感受到了历史的使命感和责任感。
In the early days of the founding of New China, the industrial foundation was weak. With the help of East German engineers dispatched by the Soviet Union, China built the largest grinding wheel factory, the Zhengzhou No.2 Grinding Wheel plant. The factory building has the typical Bauhaus architectural style, and it also became an important pillar industry in Zhengzhou at that moment. It is the memory of the times in the hearts of every Zhengzhou people. In the largest Bauhaus complex in Asia, old-fashioned Soviet buildings made of concrete slabs dominate, with giant cedars and plane trees growing between the buildings, intricate piping systems, ubiquitous grinding wheel molds, and abandoned industrial production tools. The heavy historical atmosphere, profound industrial traces, and strong visual impact make us feel the sense of mission and responsibility of history.

是传承，还是摒弃？要利用，如何利用？想重生，以何种形式重生？如何让二砂带着今天的时代使命重回郑州人的日常生活？如何有效利用老厂区的历史遗存，在保护的同时赋予它们新的时代意义与功能成为本次项目首先需要解决的现实问题。
Inheritance or Abandonment? To utilize, and how to use? Want to be reborn, and in what form? How to make the 2nd grinding wheel plant return to the daily life of Zhengzhou people with today’s mission of the times? The priority issue in this project is how to effectively use the historical relics of the old factory area and give them new era significance and functions while protecting them.
设计策略 DESIGN STRATEGY
二砂厂历史的重生体现在厂区历史遗迹的保留重塑，以及景观生态环境的打造。以“记忆重生”为设计愿景，景观设计尊重老厂区原有空间格局，重新梳理场地公共空间布局，还原厂区包豪斯现代主义建筑风貌，通过改造赋予老物新生。
We take “Rebirth of memory” as the design vision. The preservation and reconstruction of the historical relics reflect the rebirth of the No.2 grind wheel plant and the ecological landscape environment. The landscape design respects the original spatial pattern of the old factory area, reorganizes the public space layout of the site, restores the Bauhaus modernist architectural style of the factory area, and gives new life to the old things through renovation.

考虑到低成本和简易工艺水平的要求，景观设计中采用梧桐树压印混凝土的办法，增加混凝土的细节。当年由东德、捷克、苏联捐赠的工业机械如今已经废弃，我们将其回收，改造成游乐设施、景观构筑物，错综复杂的管道和仪表盘也被重新利用，融入标识系统。
We salvaged the industrial machinery donated by East Germany, the Czech Republic, and the Soviet Union and transformed them into amusement facilities, landscape structures. Considering the requirements of limited budget and simple craftsmanship, we used the method of embossing concrete with plane trees to increase the details of the concrete. We also reused and integrated the intricate pipes and instrument panels into the signage system.

二砂厂内原有的近 2000 棵古树也被全部被保留，同时适当增加当地树种，与城市的各个方向的绿色通道相联系，成为该区域生态系统的重要支撑。
The original nearly 2,000 trees in the 2nd grinding wheel plant have also been preserved. Local tree species have been appropriately increased to connect with the green passages in all city directions and become essential support for the regional ecosystem.

节点设计 NODE DESIGN
从二砂厂原本的工业文化基因与历史记忆出发，场地空间划分为有层次的三部分：钻石广场、砂轮乐园以及二砂绿廊，并通过枫香树阵、中央大道、梧桐大道串联。以“天圆地方”的概念梳理场地肌理，方正的直线主轴线，重要的空间节点处穿插圆形的砂轮，形成不同尺度和功能的空间，激发不同层次的公共活动。
Starting from the original industrial, cultural genes, and historical memory of the 2nd grinding wheel plant, the site is divided into three parts: the diamond plaza, the grinding wheel park, and the ersha green corridor, which are connected in series through the sweet gum woods, central avenue, and Wutong avenue. The texture of the site is sorted out with the concept of “round sky and square earth.” The straight axis of the Main Square and circular grinding wheels are interspersed at important space nodes, forming different scales and functions and stimulating public activities at different levels.

前广场的上空以记忆之环承载着“革命友谊”，直径40.2米，上刻曾为二砂建设付出努力的170位东德工程师和劳模名字，作为见证革命友谊的地标。记忆之环由四个钢柱悬索牵制，与地面上的320个象征无名英雄的星光灯遥相呼应。保留的雪松、场地的右侧的一系列混凝土柱与管道形成了强烈的视觉与动线引导。
The sky above the front square carries the “Revolutionary Friendship” with a 40.2-meter memorial ring. The names of 170 East German engineers and model workers who have worked hard to construct the 2nd grinding wheel plant are engraved on it as a landmark to witness the revolutionary friendship. The Ring of Memory is restrained by four steel pillar suspension cables, echoing the 320-star lights on the ground that symbolize unsung heroes. The retained cedar, a series of concrete columns, and pipes on the right side of the site form a solid visual and moving line guidance.

砂轮乐园是将厂区原有生产工具重新利用而成的运动公园，以“砂轮”为设计母题，废弃的机器被改造成攀爬网、滑梯、座椅等儿童游乐互动设施。这些工业遗迹虽然没了生产价值，却在重生后被赋予新的功能与意义，以另一种形式为城市发光发热。
The grinding wheel park is a sports park that reuses the original production tools in the factory. Although these industrial relics have lost their production value, they have been given new functions and meanings after being reborn, and they have served the city in another form. With the theme of the “grinding wheel,” the abandoned machines are transformed into interactive facilities for children such as climbing nets, slides, and seats.

体验园以“微更新”的手法设计了一个与厂房建筑高度融合的体验空间，最大化地保留了二砂的特色和记忆：保留场地内原有树木，如雪松和梧桐；将原有混凝土铺装块砸碎，融入铺装；将曾经的报亭变成城市休息空间；重新利用废弃绿地，改造为游乐公园；废弃的鼓风机化身景观雕塑；砂轮的磨具垒成植物绿墙，重新激活着小空间。
The experience garden has designed a space that is highly integrated with the factory building with the method of “micro-renewal,” which maximizes the preservation of the characteristics and memory of The 2nd grinding wheel plant: the original trees in the site, such as cedar and sycamore, are preserved; the original concrete blocks are smashed and integrated into the pavement; the former newsstand is turned into an urban rest space; the abandoned green space is reused and transformed into an amusement park; the abandoned blower is transformed into a landscape sculpture; the grinding wheel is built into a green wall of plants, reactivating the small space.

▽在时间的维度上进行“新”的叠加，同时依然需要保留下“旧”的部分，最终实现“新”与“旧”的碰撞。 Urban renewal is the superposition of “new” in the dimension of time, and at the same time, it is still necessary to retain the “old” part, and finally realize the collision of “new” and “old”.
