            ① 砼剛澆筑完成,未初凝就被踩踏,或被水沖刷。 

            ② 砼強度未達要求(1.2MPa)就上人作業、過早堆載等,使砼表面損壞、開裂。 

            ③ 拆模過早或被撞擊,導致砼破損、開裂。


            防治措施:

            ① 施工中,不得用重物沖擊模板,不準在模板和支撐上搭腳手架,以保證模板牢固、不變形。 

            ② 側模板應在砼強度能保證其邊角和表面不受損傷時,方可拆模。 

            ③ 砼澆筑完成后,待其強度達到 1.2MPa 以上,方可在上面進行下道工序施工。 

            ④ 預留的管線、螺栓及插筋,在澆砼時不得碰撞,或使之產生位移。按設計要求預留孔洞或預埋件,不得以后鑿洞埋設。
