Precast concrete square pile damage repairing method
The invention relates to a precast concrete square pile damage repairing method. The method comprises the following steps that the damaged position of a precast concrete square pile is cleaned; filling materials are placed at the damaged parts; filling the damaged part with an adhesive; shaping the adhesive at the damaged part; pressing on the adhesive by using a shaping template; and the shaping template is removed after maintenance. According to the precast concrete square pile damage repairing method, the metal fibers are embedded, the buckles with the steel bars are formed, and the repairing strength is higher than that of cement mortar and grouting materials; after the paper is coated with the separant, mold erecting and demolding are convenient, other hoops are not needed, turnover is convenient, and mass use is achieved; repair and maintenance are convenient; and as the epoxy resin is black, whether the position where the reinforcement is exposed fractures or not in the piling process can be clearly judged.
本发明涉及一种预制混凝土方桩破损修补方法，包括如下步骤：清理预制混凝土方桩的破损处；在破损处放置填料；在破损处填充粘合剂；对破损处的粘合剂进行整形；用定型模板压在粘合剂上；养护后去掉定型模板。本发明提供的预制混凝土方桩破损修补方法，嵌入金属纤维,并形成与钢筋的卡扣,比水泥砂浆和灌浆料修补强度高；纸张涂隔离剂后支模脱模方便,无需其他箍件,周转方便,大量使用；修补养护方便；因为环氧树脂呈黑色,可以清晰的判断出露筋的位置在打桩过程中是否断裂。
