摘要
大面积厚地坪采用软缝,可一次浇筑不留施工缝;使用内燃式振动梁找平混凝土,通过埋设振动梁轨道控制地坪标高表面平整度;接槎处设凹槽控制平整度和表面质量;采用严格控制坍落度和二次振捣工艺,控制和减少沉陷量;采用机械抹光工艺,提高抹面速度及质量;及时切割诱导缝,减少了裂缝发生的可能性。
Super sized fiat ground in which soft joint is adopted can be concreted by one time without reserving construction joints. Internal combustion vibrating beam is used to level the concrete, and the top smoothness of the flat ground is controlled by embedded vibrating beam rail while the smoothness and face quality of the connecting joint is controlled by arranging indent. By strictly controlling concrete slump and second vibration technique, settlement amount is reduced, and by mechanical troweling technique, troweling speed and quality are improved. Through cutting inductive seams timely, cracking possibility is reduced.
