超效缓凝砂浆包裹于预应力钢筋上形成一种新颖独特的缓粘结预应力混凝土,它省去了施工过程中需成孔、穿索和压浆等工序,并达到有粘结预应力混凝土的效果。此技术属国内首创。1994年经上海市成都路高架桥梁工程使用,证明能大大提高施工效率,缩短工期,降低造价。1996年获甘肃省教委科技进步二等奖。
The super-effective retarding mortar is wrapped on the prestressed steel bar to form a novel and unique slow-bonding prestressed concrete, which eliminates the need to form holes, threading, and grouting in the construction process, and achieves a bonded prestressing force. The effect of concrete. This technology is a domestic initiative. In 1994, the use of the Chengdu Road elevated bridge project in Shanghai proved that it can greatly increase the construction efficiency, shorten the construction period, and reduce the cost. In 1996, he was awarded the second prize for scientific and technological progress by the Education Commission of Gansu Province.
