【摘要】 冬期滑模施工 ,应对混凝土配合比进行严格试配 ,并选取最佳混凝土配合比方案。必须严格控制好混凝土坍落度 ,严格控制混凝土的出罐及入模温度 ,并根据混凝土贯入阻力试验及所对应砂浆强度来控制混凝土的提升时间和滑升速度 ,同时 ,对施工中出现的技术问题应及时解决 ,从而保证滑模施工在冬季的顺利进行更多还原

【Abstract】 Slip form construction in winter,we should test strictly on concrete mix proportion,and elect the best precept.We must control strictly the slump of mix,and the temperature of the mix machine out and mold in,we should control the time and velocity of slip form according to the peretration resistance and the mortar strength of the concrete.At the same time,we should slove the problem in time in order that assure the construction go on smoothly in winter.更多还原
