云南鲁布革水电站引水隧道工程水泥用量,国内计算机为9.8万吨。而负责施工的日本大成公司的用量仅为5.2万吨,相差约4.6万吨。大成公司大量节约水泥的办法究竟是什么?曾引起我们施工企业的普遍关注。一、严格按设计要求和工艺要求施工大成公司开挖岩石隧洞(断面直径8.8米),采用控制爆破一次成型,把超挖量控制在最低限量,由此减少因超挖量过大而增加的混凝土浇
The amount of cement used for diversion tunnel construction at the Lubuge hydropower station in Yunnan was 98,000 tons of domestic computers. The amount of Japanese Dacheng company responsible for construction was only 52,000 tons, a difference of about 46,000 tons. What exactly is Dacheng’s strategy for substantial savings in cement has caused widespread concern in our construction companies? 1. The Dacheng Company was excavated in strict accordance with design requirements and technological requirements. The excavation of the rock tunnel (diameter of 8.8 meters in section) was controlled by one-shot forming and the amount of over-excavation was controlled to the minimum amount, thereby reducing the increase in over-excavation volume.
