摘 要:通过对套筒灌浆连接用灌浆料九种不同龄期(1、2、3、4、5、7、14、21、28 d)试件进行抗压强度试验,得到了灌浆料强度与龄期之间的关系,建立了灌浆料强度的预测增长曲线。结合GT16、GT18、GT20三种规格的套筒灌浆连接用灌浆料强度预测增长曲线,研究了套筒灌浆连接接头抗拉强度与灌浆料强度之间的关系,得到了GT16、GT18、GT20三种规格的套筒灌浆连接接头满足抗拉强度条件下的灌浆料最小抗压强度值。可为相关工程套筒灌浆连接用灌浆料强度偏低的质量缺陷处理提供参考。
Abstract: The compressive strength of the grouted specimens in the sleeve grouted joints at different ages (1, 2, 3, 4, 5, 7, 14, 21, 28 d) was tested, the relationship between grout strength and age was obtained, and the predicted growth curve of grout strength was established. The relationship between the tensile strength of sleeve grouting joint and the strength of grouting material was studied by combining the predicted growth curve of the strength of grouting material in the sleeve grouting joint of GT16, GT18 and GT20, three specifications of sleeve grouting joints meeting the tensile strength of the minimum compressive strength of grouting materials (the strength threshold of grouting materials) was analyzed. The research results provide a basis for the treatment of the quality defect of low strength grouting material for sleeve grouting connection joints in related engineering.
