特大直径雨水干管顶进关键施工技术

Key Construction Technology for Top Entry of Rain Water Main Pipe with Large Diameter

以太原市水西关道路改造工程(解放路至滨河东路)雨水干管为背景,对DN3500mm特大直径雨水干管顶进施工关键施工技术进行了论述,探讨了特大直径雨水干管穿越主干道顶进施工采取的技术措施,工程施工后满足了施工要求,保证了城市道路顶进施工顺利进行。

Based on the rain water main pipe of Shuixiguan Road Reconstruction Project （Jiefanglu to Binhe East Road） in Taiyuan City, this paper discusses the key construction technology of the top entry construction of the DN3500 mmextra-large rain water main pipe. This paper probes into the technical measures adopted in the construction ofmin water trunk pipe with extra large diameter passing through the top of the main road. The project meets the construction requirements after construction and ensures the smooth construction of the urban road jacking.
