东三环亮马桥改建展宽工程,桥梁下部结构为混凝土钻孔桩,两侧展宽共16根桩,为配合亮马河冬灌后断水,春灌前放水,故钻孔桩施工在严冬季节,为保证钻孔桩接桩的质量,决定采用蒸气养护,以提高混凝土强度,蒸养设备是一台14吨火碾供气。因桩位分散施工中供气量不能满足两根桩的同时施工,需另增加一台14吨火碾。我们根据水分子运动和水位差的原理,利用现有设备,
East Third Ring Liangma Bridge reconstruction widening project, the lower part of the bridge structure for the concrete bored pile, both sides of the extension of a total of 16 piles, in order to tie with the Liangma winter flood irrigation, drainage before spring irrigation, so the construction of bored piles in the winter season, in order to ensure drilling The quality of the post-pile piles, decided to use steam curing, in order to improve the strength of concrete, steam curing equipment is a 14 tons of fire grind gas supply. Due to the pile of scattered construction gas supply can not meet the simultaneous construction of two piles, need to add another 14 tons of fire grind. We based on the principle of water movement and water level difference, the use of existing equipment,
