玉环县温门三期围垦工程目鱼屿排涝闸混凝土裂缝成因分析及处理

摘要

Concrete cracks are common defects in hydraulic structures which can affect their appearance, durabih＇ty and structural safety. Through causal analysis of corm.fete cracks in sluices of Xuarmaen Reclamation Project （Phase Ⅲ ）, the study put forward principles of chemical pouting and surface water proofing treatment for concrete cracks. Quality sampling tests suggest that chemical grouting achieved the desired objectives of seepage control and reinforcement.%混凝土裂缝是水工建筑物常见的缺陷之一，往往会影响到水工混凝土建筑物的外观、耐久性以及结构安全。通过对玉环县漩门三期围垦工程水闸混凝土裂缝的成因分析，确定了混凝土裂缝化学灌浆和表面防水的处理原则。质量抽样检验表明，混凝土裂缝化学灌浆达到了防渗、补强的预期目的，取得了较为理想的工程处理效果。
