摘　　要：随着城市发展程度的提高,施工场地越发紧缩,城市中深基坑施工更是困难,而采用全逆作法施工技术能良好解决这一问题。逆作施工过程中配电线路如何敷设,临时用气、用水管道如何架设,是当前的一个重难点。为解决在深基坑全逆作法施工过程中,地下室临时用水、电、气等配套设施的布设问题,提高施工效率,针对全逆作法楼板先行施工的特点,将临时用气、用水管道悬挂在楼板底部,将配电线路以桥架敷设的方式悬挂于梁下,有效解决了工程实际问题,具有明显的社会效益和经济效益。With the improvement of the degree of urban development,the construction site is becoming more and more compact,the construction of medium and deep foundation pit in the city is more difficult,and the reverse construction technology can solve this problem well.How to lay distribution lines during reverse construction and how to set up temporary gas and water pipelines is an important and difficult point at present.In order to solve the problem of the layout of temporary water,electricity,gas and other supporting facilities in the basement during the reverse construction of the deep foundation pit,and to improve the construction efficiency,Hunan Construction Engineering Group Co.,Ltd.According to the characteristics of the construction of the floor slab in advance,the temporary gas and water pipes are suspended at the bottom of the floor,and the distribution lines are suspended under the beam by the way of bridge laying,which effectively solves the practical problems of the project and has obvious social and economic benefits.
