一级轻型井点配合局部深井在深基坑降水中的应用

Application of the coorperation of first class light well with local deep well in the foundation pit drainage

针对基坑降水在 5～ 6m时 ,一级轻型井点实际效果不太理想的情况 ,设计采用一级轻型井点配合局部深井降水 ,通过在实际工程中的应用取得了较好的降水效果 .在施工中采取回灌井点等技术措施 。

When the first-degree light well point has no good practical results in view of the base pit precipitation at five to six meters,the first-degree light well point coordinated with the partial deep well precipitation which has been designed and applied to the practical projects has achieved better precipitation results.By taking technical measures like return irrigation well point under construction,it can also effectivelly control the negative influence on the surroundings from precipitation.
