郑州金水路改造更新中地下交通设施设计

Design of Underground Transportation Facilities in Reconstruction and Renewal of Jinshui Road in Zhengzhou

郑州金水路是城市中心东西向联系的交通要道,该路上高架桥的建设虽然缓解机动车通行问题,却使该路失去了原有人文景观。该路改造更新涉及较多方面,分别阐述该路机动车地下通道设计、绿地与地下车库的结合设计以及非开挖人非地下通道设计;给出高架桥梁拆除和隧道挖掘过程中的保通方案;为确保地铁与地面道路不间断运营,采用管幕顶进法施工人非地道矩形箱涵;结合建筑前区或新增公共绿地设计地下停车库,有效解决该路机动车停放难题。该设计为在适当满足机动车通行和停放需求下城市中心核心区道路改造更新提供有益的探索和借鉴。

Jinshui Road in Zhengzhou is the traffic thoroughfare connecting the city center from east to west. The construction of the elevated bridge on this road can ease the traffic congestion, but will make this road lose its original human landscape. The reconstruction and renewal of this road will involve many aspects. The design of underground channel for the motored vehicles of this road, the combined design of the greenbelt and underground parking, and the design of trenchless underground channel for the pedestrians and non-motored vehicles are set forth respectively. The traffic guarantee schemes for the demolition of elevated bridge and the tunneling process of tunnel are given. In order to ensure the continuous operation of metro and ground road, the rectangle box culvert of pedestrian and non-motored vehicle is constructed by the pipe curtain jacking method. Combined with the building proparea or the newly added public green space, the underground parking is designed effectively to solve the parking difficulties of the motored vehicles in this road. This design provides the beneficial exploration and reference for the reconstruction and renewal of the roads in the urban central core area under the demand of properly satisfying the traffic and parking of the motored vehicles.
