浅谈顶管施工工艺

顶管施工技术近年来在我国发展迅猛。顶管施工采用油压驱动，施工时噪音远远小于开槽式敷设管道，几乎没有地面沉降的现象；将作业面移人地下，从而避免了对地面交通的影响；而且在较深的埋深情况下施工成本要小于开槽式敷设管道。该文结合九江市龙开隧道整治工程施工实际情况，对顶管施工工艺以及在污水处理工程中的应用作了简要阐述。

Elementary Discussion on Pipe Jacking Construction Technology

The pipe jacking technology has been quickly developed in China in recent years. The pipe jacking construction uses the hydraulic driving. The noise during the construction is far lower than the channeling paving pipe almost without the appearance of the ground settlement. The construction is removed into the underground so as to avoid the influence on the ground traffic. And the construction cost under the condition of the deeper embedment will be less than the channeling paving pipe. According to the prac...
