Return water beam leakage maintenance construction method
The invention discloses a water return beam leakage maintenance construction method. The method comprises the following steps of S1, on-site cleaning and investigation, S2, grouting hole drilling, S3, grouting and S4, surface closing-up. The step S2 comprises the substeps: S21, determining hole positions: selecting the hole positions in a crossed mode along two sides of the crack, wherein the separation distance between the hole positions and the crack is 2-3 cm, and the separation distance between every two adjacent hole positions on the same side of the crack is 25-50 cm; S22, drilling: conducting drilling operation on the selected hole positions in sequence, making drilled holes penetrate through cracks during drilling, but not punch a structural plate through, wherein the drilling angle is not larger than 85 degrees; S23, nozzle burying: mounting a water stop needle head in a grouting hole and screwing the same tightly, wherein no gap exists between the outer wall of the water stop needle head and the hole wall; and S24, hole site verification: injecting clean water into the water stop needle head, and observing whether the clean water can overflow from an adjacent hole or not; if the overflow can be carried out, carrying out next operation, and if the overflow cannot be carried out, checking the hole. The method can effectively solve the problem of leakage of cracks of the return water beam, so that the waterproof effect of the return water beam is improved, and durability is good.
本发明公开了一种反水梁渗漏维修施工方法，包括如下步骤：S1、现场清理勘验，S2、钻灌浆孔，S3、灌浆，S4、表面收口；S2包括：S21、孔位确定：沿裂缝两侧交叉选取孔位，并使孔位距离裂缝2‑3cm,裂缝同一侧的相邻两孔位间距为25‑50cm；S22、钻孔：对选取的孔位依次进行钻取操作，钻取时需使钻孔穿过裂缝，但不得打穿结构板，且钻孔角度不大于85°；S23、埋嘴：在灌浆孔内安装止水针头，将其拧紧，使止水针头外壁与孔壁之间无间隙；S24、孔位校验：向止水针头内注入洁净水，观察洁净水是否能从邻近的孔内溢出；若能溢出，则进入下一步操作，若不能溢出，需对孔进行检查。本发明能够有效解决反水梁裂缝的渗漏问题，提高反水梁防水效果，而且耐久性好。
