电力隧道断面选型与机械化施工

A Study on the Model Selection of the Section for the Power Tunnel and the Mechanized Construction

随着我国城市的不断发展,城市供电主网和配网的敷设方式发生了巨大的变化。传统的以架空线路电能输送方式正快速向地下电缆的敷设方式转变。相对于公路隧道、铁路隧道等,目前的电力隧道截面选型通常按敷设电缆的规模和运检方式来确定,截面型式多样,很少从机械化施工的角度来确定断面尺寸。本文提出从两方面扩大电力隧道机械化施工:一种方式是通过改变隧道断面形式,减少断面尺寸种类,结合现有机械设备尺寸归并出几个适用范围广的隧道断面尺寸;另一种方式是鼓励设备厂家研发出适用于电力隧道特点的机械设备。

With the development of cities in China,the ways of laying main and distribution networks in cities have changed a lot. Traditional overhead lines are being rapidly replaced by underground cables. Compared to the model selection of the section for vehicular and railway tunnels,that of the power tunnel is usually decided by the scale of the cable and the ways of operation and maintenance. Although there are various section models,the size of the section is seldom decided from the perspective of mechanized construction. This paper poses the expansion of the mechanized construction of the power tunnel in two aspects: one is to summarize some sizes of the section of the tunnel with a wide range of application by changing the form of the section and reducing the sizes of the section based on the size of the current mechanical equipment;the other is to encourage the manufacturer of the equipment to develop mechanical equipment suitable for the features of the power tunnel.
