Study on Long Distance Pipe Jacking Construction Technology of Municipal Water Supply and Drainage

With the continuous acceleration of urbanization, municipal engineering has made remarkable achievements.Municipal water supply and drainage engineering is an important infrastructure to ensure the normal operation of the city. How to improve the construction quality has become the focus of attention. Restricted by factors such as underground pipelines and above-ground buildings, the current underground construction is often used in the construction of underground excavation methods, such as pipe jacking construction technology.. Compared with other processes,pipe jacking method can save land, reduce earthwork volume, and do not need to interrupt traffic, with little impact on the environment and traffic. Combined with a specific project case, this paper puts forward the construction technology of reinforced concrete long-distance pipe jacking, expounds its advantages, and on this basis, discusses the key points of construction technology, in order to effectively improve the construction quality.
