一、外墻套管式對拉螺桿屋頂防水密封工序：
First, the outer wall casing pipe on the pull screw waterproof sealing process:
1. 擴大對拉螺桿兩端部位混凝土并成漏斗狀，剔除多余套管。
1 expand the concrete at both ends of the pulling screw and funnel shape, remove excess casing.
2. 墻體外側采用聚合物氯丁膠乳水泥砂漿封堵，并養護14d。
2 outside the wall of the use of polymer latex cement mortar block, and maintenance of 14D.
3. 在墻體內側對套管內灌注無壓力聚合物類水泥膠漿或硬質發泡聚氨酯材料(百度SEO優化)，要求嵌填精密，外觀平整。
3 in the inner side of a wall of polymer cement mortar or rigid polyurethane foam material without pressure on casing filling, filling the requirements of tight, smooth surface.
4. 在墻體迎水面一側(河南人事考試網站)，施工螺桿位置涂刷1.5mm厚聚合物水泥屋頂防水涂料附加層，附加層范100 x 100mm。
4 in the wall facing the water side, the construction of the construction of the screw position 1.5mm thick polymer cement waterproof coating of the additional layer, additional layer fan 100 100mm X.
二、外墻嵌固式對拉螺桿屋頂防水密封工序：
Two, the external wall inlay solid type to pull the screw waterproof sealing process:
1. 逐個剔除墻體內、外側對拉螺桿根部混凝土，并形成漏斗狀。
1 to remove the wall, the outer side of the screw root concrete, and form a funnel shape.
2. 清理浮塵碎屑并澆水濕潤。
2 clean dust debris and water.
3. 用聚合物氯丁膠乳水泥砂漿封堵內外側螺桿孔凹槽并壓實抹光。
3 use polymer chloride latex cement mortar to block the internal and external screw hole groove and press the light.
4. 在墻體迎水面一側，施工螺桿位置涂刷1.5mm厚聚合物水泥屋頂防水涂料附加層，附加層范100mm x 100mm。
4 in the wall facing the water side, the construction of the construction of the screw position 1.5mm thick polymer cement waterproof coating of the additional layer, the additional layer fan x 100mm 100mm.
