摘 要:介绍了预应力简支T形梁混凝土施工中常见的几种质量缺陷,结合工程实际,分析了产生缺陷的原因;提出了相应的预防措施和处理措施。针对预应力混凝土简支T形梁危害较大的质量缺陷—孔洞做了重点论述,并结合试验与现场施工验证,将补偿收缩混凝土应用于混凝土孔洞修补中,结果表明,补偿收缩混凝土用于修补混凝土孔洞是可行的。
Abstract: The common quality defects in the concrete construction of prestressed simple branch T-shape beams are introduced. Combining with project practices, the reasons for the defects are analyzed and the relevant preventive and treatment measures are proposed. The more harmful quality defect—holes in the prestressed concrete simple branch T-shape beams is significantly discussed, and the shrinkage-compensating concrete is applied in the concrete holes repairing combined with the test and field construction verification. The results show that the shrinkage-compensating concrete applied in the concrete holes repairing is feasible.
