上海白龙港8座预应力混凝土蛋形消化池,单池容积12400m3,总体规模目前位居亚洲第1。为满足工期要求,8座池的闭水闭气试验基本同步实施。工程体量大,监测任务重。对闭水、闭气试验的验收标准,工序安排、试验要点、试验期间的池体沉降及应力监测技术等问题进行了探讨。可为预应力消化池功能性验收方面的规范编制提供参考。
Shanghai Bailonggang 8 prestressed concrete egg-shaped digesters, single-cell volume of 12400m3, the overall size of the current Asia’s No. 1. In order to meet the requirements of the construction period, the closed-water and closed-air test of 8 pools was basically implemented synchronously. Engineering volume, monitoring tasks heavy. The acceptance criteria of closed water and gas closed test, process arrangement, key points of test, settlement of cell body during the test and stress monitoring technology are discussed. For pre-stressed digesters functional acceptance of the preparation of norms provide a reference.
