- 摘要:
- 结合管道穿越工程实例，阐述了无土围堰技术的原理和做法。具体从确定围堰位置、做围堰骨架、铺设支撑板及采取的防渗水措施等方面进行了详细介绍。实际应用表明，该技术具有操作简单、施工方便、劳动强度低、施工成本低、不破坏环境、无需进行后期清理工作等优点，具有一定的推广应用价值。同时还指出了施工中应注意的问题及适应范围。
By taking the pipeline crossing as a practice example,the writer expounded the principle method of earthless cofferdam technique and introduced the determination method of cofferdam location,skeleton structure of cofferdam,lay down of support board waterproofing measure etc.in detail.It has been proved by practice application that the method has many advantages such as simple convenient operation,low labour strength,less cost,no-damage to the environment no-need latter clearance and is worth being used widely.Also,the writer pointed out the cautions application limits.2001,5(5): 19-20,23 收稿日期：2001-3-27作者简介：罗志强，工程师。1995年毕业于西安石油学院机械系焊接工艺与设备专业，一直在管道储运介司工程公司从事技犬工作。负责了多座人型油罐的修理及加热炉、锅炉的修理和安装技术工作。通讯地址：江苏省徐州市，邮编：221008
