水工建筑物加固与修复中 ,经常要在老混凝土上浇筑新混凝土。新的方法是在老混凝土上打孔植筋 ,用高强结构胶代替水泥砂浆固结 ,可大大减少植筋深度 ,对原混凝土损失小 ,粘结可靠性高。用WSJ结构胶进行试验表明 :植筋深度较浅 ,混凝土锥面破坏 ;植筋深度较深 ,钢筋拔出 ;植筋更深 ,钢筋破坏 ;说明固结效果良好。 Of hydraulic structures reinforcement and repair, often in the old concrete pouring new concrete. The new method is to drill holes in the old concrete planting bar, with high-strength structural adhesive instead of cement mortar consolidation, can greatly reduce the planting depth, the original concrete loss, high bonding reliability. Experiments with WSJ structural adhesive showed that: the depth of planting bar was shallow and the conical surface of concrete was damaged; the depth of planting bar was deeper and the bar was pulled out; the planting bar was deeper and the bar was damaged;
