煤制天然气装置复杂成分填料填方地基强夯处理
|
摘要
煤制天然气装置对地基的变形、稳定性要求严格。针对场地实际情况,采取了相应的整平和夯实方案,并对分层碾压法和强夯法进行了比较。通过试验,确定了强夯的总体方案,并对特殊部位和冬季施工采取了相应的处理措施。检测结果表明,各项指标及沉降量均满足规范和设计要求。
Coal gas device has very strict requirement on the deformation and stability of its foundation.Corresponding leveling and tamping methods were selected according to the site condition,and comparison was made between lateral rolling method and dynamic compaction method.The general scheme of dynamic compaction was determined based on test results.Treatment measures were adopted for special locations and winter construction.Detection results show that all indexes and the settlement can meet the design requirements.
