Composite well sealing method for ultra-deep foundation pit drainage well
The invention relates to the field of keeping an underground foundation section or other areas dry by lowering the underground water level, in particular to a composite well sealing method for an ultra-deep foundation pit drainage well. The composite well sealing method for the ultra-deep foundation pit drainage well is implemented according to the following steps that firstly, an overall underground structure cushion layer is constructed; 2, acrylic acid waterproof construction of the drainage well; thirdly, a drainage well waterproof protection layer is constructed; fourthly, the drainage well is filled with graded gravel; fifthly, concrete with the same mark number as the raft plate is poured in a layered mode; sixthly, the opening of the steel sleeve is filled with water stopping glue which swells slowly when meeting water; 7, covering the opening part of the steel sleeve with a steel cover plate, and performing angle welding; 8, acrylic acid is laid for waterproofing; and ninthly, raft plate construction is conducted. The manufacturing cost is reduced, and the waterproof performance is improved.
本发明涉及通过降低地下水位保持地下基础地段或其他面积的干燥领域，具体为一种超深基坑疏干井复合封井方法。一种超深基坑疏干井复合封井方法，按如下步骤依次实施：步骤一、整体地下结构垫层施工；步骤二、疏干井丙烯酸防水施工；步骤三、疏干井防水保护层施工；步骤四、疏干井填充级配砂石；步骤五、分层浇筑与筏板标号相同的混凝土；步骤六、在钢套管口部填充遇水缓膨胀止水胶；步骤七、将钢盖板盖到钢套筒口部并进行角焊；步骤八、铺贴丙烯酸防水；步骤九、筏板施工。本发明降低造价，提高防水性能。
