青城子铅矿榛子沟坑副竖井,春季涌水量每小时1.6m~3,雨季达每小时11m~3,不仅淋湿乘罐人员的衣服,同时恶化井口作业条件。每到冬季结冰期,由于钢绳带水,常常使天轮槽内结满冰,而不得不停下罐笼进行处理,给安全和生产造成严重威胁。为此,我们采用风筒布形成隔离层的办法,较好地解决了这个问题。隔离层的结构如附图所示。在每架钢梁 Qingchengzi lead mine hazelnut furrow pit shaft, spring influx of water per hour 1.6m ~ 3, the rainy season up to 11m ~ 3 per hour, not only wet the canning staff clothes, while deteriorating wellhead operating conditions. Every ice season in winter, due to the rope with water, often make day round groove full of ice, and had to stop the cage for handling, posing a serious threat to safety and production. For this reason, we adopt the method of forming the isolation layer with the wind tube cloth, have solved this question well. The structure of the isolation layer is shown in the attached figure. On each steel beam
