摘要
钢顶管减阻泥浆孔的水压试验是地下管线施工质量的重要保证,传统施工方式效率较低、操作笨重。为了改善这种情况,探讨并介绍了一种更为高效、安全的钢顶管内减阻泥浆孔水压试验装置及使用方法。该设备采用创新的方法,经过多次方案修改讨论及对废料管的模拟试验,具有比传统方法更为突出的优势。该新型设备具备多孔同步试压,数倍提高施工效率,节省了施工时间与成本,保证了施工质量,可供类似工程参考和借鉴。
The hydraulic test of steel pipe-jacking anti-drag slurry hole is the important guarantee of the underground pipeline construction quality. The traditional construction methods are inefficient and cumbersome in operation. In order to improve this situation, the article discusses and introduces a more effective and safe hydraulic test device and a using method of steel pipe-jacking anti-drag slurry hole. This equipment adopts the innovative method. After modification and discussion of the schemes for many times,and the simulative test of waste pipe, it has the more highlighted advantage than the traditional methods. This new equipment has the property of multi-hole synchronized pressure test to improve the construction efficiency for several times, to save the construction time and cost, and guarantee the construction quality,which can be referred for the similar projects.
