2、设一个深井井点。每栋楼为一个施工工段。4.降水材料：抽水机具为7.5KW深井深井抽水泵。5、降水期间，必须注意观测降水对周围建、构筑物、管线等沉降情况有无变化，以便及时调整抽水量，确保周围建筑物或管理等的安全。6.深井井点降水施工程序为：井位放样打井机就位打井安装抽水控制电路试抽降水井正常工作。7.为保证降水和砼施工的连续性，施工期间电源不得停断，故施工现场必须配置一台负载相符的发电机作为施工备用电源。8.抽水：井点降水管全部安装完毕后进行试抽。当抽水设备运文档编码:CZ6D9I4N7G2 HY1C8Y10T8C8 ZC8V8T1V5W3文档编码:CZ6D9I4N7G2 HY1C8Y10T8C
