摘 要:分析了低负温型管道压浆料的技术原理,研究了水灰比、浆体温度、风速、搅拌时间以及储浆罐容积等对凝结时间及流动度经时损失的影响。通过制定合理的压浆施工工艺,以及预应力混凝土梁模拟灌浆后降温试验,验证了管道压浆冬季施工的可行性。
Abstract: The technical principle of low negative temperature pipeline slurry was analyzed, the effects of water cement ratio, slurry temperature, wind speed, stirring time and storage tank volume on the setting time and the loss of fluidity over time were studied. The reasonable process on pressure grouting construction and the test of the prestressed concrete beam to simulate the cooling after grouting were carried out to verify the feasibility of pipeline grouting winter construction.
