实际上、公用设施——如供水、雨水排泄、供电及供煤气等设施—设在地下已有多年历史了。自古以来、设置地下设施的优点即已非常明显——然而,以下所举的古今公用设施项目却反映出这些系统常常没有利用综合规划来进行设计。在许多实例中,地下开发工程沿用了地面建设的摸式:管道、电缆和沟渠基本上都沿着街道布置。如果说对都市隧道的要求在不断增加的话——例如,区域供热与电信——那就需要有一条灵活的、创新的途径来避免地下空间“拥挤””。目前、第一个开发者几乎可以完全由地决
In fact, utilities such as water supply, rainwater drainage, electricity supply and gas supply facilities have been underground for many years. The advantages of setting up underground facilities have been obvious since ancient times. However, the following ancient and modern public facilities projects reflect that these systems often do not use comprehensive plans for design. In many instances, underground development projects follow the pattern of ground construction: pipes, cables, and canals are basically laid along streets. If the demand for urban tunnels continues to increase - for example, district heating and telecommunications - then there needs to be a flexible and innovative approach to avoid “congestion” of underground space. At present, the first developer is almost It can be completely determined
