根据城市供水的需要,“八五”期间上海自来水公司专门组织力量,攻克了不断水开梯分支技术,并获得了95年上海科技成果二等奖,目前正进入推广应用阶段。一、不断水开梯技术的特点与原理:所谓不断水开梯分支工艺技术,就是在原通水运行管道上不断水、不降压、不缩流的情况下,进行分支的施工过程。它与传统的断水分支施工工艺相比,具有六大特点:1.避免了由于断水施工给沿线工矿企事业
According to the needs of urban water supply, Shanghai Water Corporation specially organized its forces during the “85” period to overcome the continuous water and water lift branch technology and won the second prize of Shanghai Scientific and Technological Achievement in 1995, which is now entering the promotion and application stage. First, the characteristics and principles of continuous water opening and closing technology: The so-called continuous water opening and closing ladder branch technology, that is, the original water running pipe on the water, no buck, no contraction of the case, the branch of the construction process. Compared with the traditional branch construction process, it has six major characteristics: 1. To avoid the construction of water and sewage to the industrial and mining enterprises along the line
