形式多样的检查井(包括圆形、矩形和异形检查井)是城市道路、密集生活小区地下排水系统、电力电信系统、城市光缆通信系统等地下管线系统必需的基础设施之一。在现有的地下管线规划模式下,每一种管线都需要单独修建自己的检查井。据行业统计显示像武汉市,道路地面检查井总数超过了一百万个;贵阳市城区道路上的各类检查井总数达四万三千多个,全国的各类检查井的市场需求量十分巨大。
Various types of inspection wells (including circular, rectangular and special-shaped inspection wells) are one of the necessary infrastructures for underground pipeline systems, such as urban roads, underground drainage systems in densely populated residential areas, power and telecommunication systems, and urban optical fiber communication systems. In the existing underground pipeline planning mode, each kind of pipeline needs to build its own inspection well. According to industry statistics, there are more than one million road surface inspection wells in Wuhan; There are more than 43000 inspection wells on the urban roads of Guiyang City, and the market demand of all kinds of inspection wells in China is very huge.
