Plugging construction method for deep foundation pit self-waterproof bottom-plate-penetrating steel pipe downcast pipe well
The invention relates to a plugging construction method for a deep foundation pit self-waterproof bottom-plate-penetrating steel pipe downcast pipe well, and belongs to the field of building construction. The construction method comprises the following steps that (1) a self-waterproof bottom-plate-penetrating steel pipe downcast pipe well embedded part is prepared; (2) a back cover self-waterproofsupporting plate embedded part is prepared; (3) a wellhead enclosure steel sleeve is prepared; (4) a well sealing bottom support mounting tool is prepared; (5) field dewatering well inspection is carried out; (6) a tube well embedded component is installed; (7) bottom plate steel bars, formworks and the embedded parts are checked and accepted; (8) an enclosure steel sleeve is mounted; (9) bottomplate concrete is poured; (10) heavy precipitation of the tube well before well plugging is carried out; (11) mounting, aligning and pressing are carried out on a supporting plate embedded part; (12)quick-setting micro-expansion high-grade concrete is poured for the first time; and (13) quick-setting micro-expansion high-grade concrete is poured for the second time, and the surface layer is compacted, subjected to roughing and maintained. The construction method has the advantages of being high in self-waterproof function, simple in structure, environmentally friendly, capable of utilizing waste, low in construction cost and the like.
本发明涉及一种深基坑自防水穿底板钢管降水管井封堵施工方法，属于建筑施工领域。所述的施工方法包括以下步骤：（1）制备自防水穿底板钢管降水管井预埋构件；（2）制备封底自防水托板埋件；（3）制备井口围护钢套筒；（4）制备封井底托安装工具；（5）现场降水井检查；（6）安装管井预埋构件；（7）底板钢筋、模板、预埋件验收；（8）安装围护钢套筒；（9）浇筑底板混凝土；（10）封井前管井强降水；（11）安装调准施压托板埋件；（12）第一次浇筑快凝微膨胀高标号混凝土；（13）第二次浇筑快凝微膨胀高标号混凝土、面层压实收光养护。本发明提供的施工方法具有自防水功能强、结构简易、绿色环保、废料利用、施工成本低等特点。
