大断面顶管掘进机特殊供电方案设计与研究

Design and Research of Special Low Voltage Power Supply Scheme for Large Section Pipe Jacking Machine

顶管掘进机使整个设备装机容量的大幅提高,同时由于顶管施工工法的特殊性,对于总的供电电缆每节都需要进行一次拆、装工作,增加了相应的施工安全风险,并降低了施工的效率。提出了几种适用于大直径顶管供电系统的设计方案,并分析在不同方案施工过程中的安全措施。

Pipe jacking drifting machine improves the installation capacity of the whole equipment. At the same time,the total power supply is supplied to the total power supply due to the particularity of the construction method of the pipe jacking. Each section of the cable needs to be demolished and installed. It increases the risk of construction safety and reduces the efficiency of construction. This paper presents several design schemes for the power supply system for large diameter pipe jacking,and analyses the safety measures in the construction process of different schemes.
