| 摘 要： | 在北京地区，我们首次成功地采用水平辐射井技术对双榆树热力隧道暗挖段进行地下降水。利用甲方的两处隧道工作竖井和另制作的一口大直径竖井，共施工水平孔３０眼，总长度达１５００ｍ，降水控制条带状隧道长度为３１０ｍ。开挖证实，降水效果显著，在地面以下降低地下水位的该项技术取得了明显的社会和经济效益。

| Abstract: | For the first time in Beijing, the horizontal well is successfully used for water lowering before concealed excavation of heating power tunnel about 310m long below the Shuang yushu district. Within a specially made round shaft, together with two other vertical shafts constructed by the first party, 30 horizontal holes totally about 1500m long were bored. On the one hand, the effect shows ground water has lowered below the site being excavated, and this kind of underground water lowering technology makes great social and economic benefits on the other hand. |
