Method for repairing outer wall of concrete circular silo
The invention provides a method for repairing the outer wall of a concrete circular silo, which belongs to the technical field of concrete construction and comprises the following steps: scanning and analyzing a concrete cylinder wall to be constructed, detecting and positioning loose concrete areas, then shoveling concrete in the areas, and shaving and chiseling existing staggered stubbles; manual steel brush rust removal is conducted on the surfaces, exposed out of the cylinder wall, of the steel bars, and a rust remover is brushed; after the steel bars are treated, L-shaped anchor bars are planted in the direction perpendicular to the cylinder wall, the distance is 300 mm, and the depth is not smaller than 100 mm; epoxy resin mortar is sprayed on the outer side surfaces of the steel bars for repairing and leveling, alkali-resistant fiber gridding cloth is pressed into the middles, and the L-shaped anchor bars are exposed; newly-added horizontal vertical reinforcing meshes are welded to the vertical L-shaped anchor bars; high-ductility concrete surface layers are pressed and plastered on the outer side of the reinforcing mesh in a layered mode, the later layer needs to be plastered in the previous layer within 4 hours, and the surface of the last layer does not need to be shiny; and carrying out surface flatness scanning detection on the high-ductility concrete surface layer, and if the surface flatness is qualified, carrying out moisturizing maintenance after final setting.
本发明提供了一种混凝土圆形筒仓外壁修复方法，属于混凝土施工技术领域，包括：对待施工的混凝土筒壁进行扫描分析,检测并定位松散混凝土区域,然后铲除这些区域的混凝土,并对存在的错茬进行剃凿；对筒壁露出的钢筋表面进行人工钢刷除锈,并刷除锈剂；在钢筋处理后,沿垂直筒壁方向种植L型锚筋,间距300mm,深度不小于100mm；在钢筋外侧表面喷涂环氧树脂砂浆修补找平,中间压入耐碱纤维网格布,露出L型锚筋；在竖向L型锚筋处,焊接新增水平竖向钢筋网；在钢筋网外侧分层压抹高延性混凝土面层,后一层应在前一层4小时内完成,最后一层表面不应收光；对高延性混凝土面层进行表面平整度扫描检测,若合格在终凝后进行保湿养护。
