市雷区间高压进洞施工方案

Construction Scheme of High Pressure into The Hole Between Municipal Government Station and Leifeng Avenue Station

文章针对市政府站至雷锋大道站暗挖区间隧道左右线往市府站方向末端电压在90 kW的输送泵电动机启动时出现电压降过大的现象,继续往前开挖将因施工用电问题无法保障二衬正常进行的情况,对此高压进洞方案开展了研究。通过研究,解决了具体工程难题。研究成果可为类似工程提供技术参考。

In this paper, according to the municipal government station to Lei Feng Avenue station tunnel line to the city station about the direction of the end voltage at the start of pump motor 90 kW when the voltage drop too much,to continue the excavation will be due to the construction of electricity can not guarantee the normal situation of the two lining,the article had carried out a study on the high pressure hole scheme.Through the research,the engineering problems were solved.The research results could provide technical reference for similar projects.
