水撼沙技术及工程试验

Water Sand Technology and Engineering Test

市政管线施工往往会引起道路病害,沟槽回填后引起不均匀沉降是一种常见的病害,也是工程技术人员研究的一个技术难点。由于水撼砂回填密实度高、节能环保等,具有推广应用前景。本文结合鲅鱼圈市政输配水管线工程地层和施工条件,介绍了水撼砂技术,采用该技术进行现场试验,并对试验结果进行深入分析,与施工后测试结果和理论分析结果进行对比验证。试验结果表明,水撼砂技术可为类似工程施工提供借鉴。

Construction of municipal pipeline frequently causes urban road diseases, while the dif- ferential settlement after trench backfill is one of the most common road diseases, and also is a key topic in terms of scientific research. Because of the advantages of high backfill density and en- vironmental care, water sand has promoted application prospect. In this paper, the construction technology of water sand is introduced in terms of the execution conditions and engineering for- mation of Bayuquan municipal pipeline project. Tests are also taken on site with the water sand technology and deep analysis is conducted comparing the test results with the theoretical analysis results. The conclusion suggests that the water sand technology can be used for reference on sim- ilar engineering projects.
