【摘要】：为选择最佳的引黄入焦引水干渠工程穿越沁河方案,通过分析穿越沁河的工程建设条件、穿越建筑物选型因素及主要穿越型式,提出了引水干渠穿越沁河技术上可行的明挖法、顶管法和定向钻法三种穿越方案;通过进一步比较分析,确定定向钻方案为最佳穿越沁河方案。研究结果不仅为断面完整性不允许破坏的河渠道穿越设计提供借鉴,也为沁河下游河段类似穿越工程设计提供借鉴。
[Abstract]:In order to select the best scheme for crossing the Qinhe River in the main channel project of diversion from the Yellow River into the coke, through the analysis of the construction conditions of the crossing of the Qinhe River, the factors of type selection of the crossing buildings and the main traversing patterns, this paper puts forward the technically feasible open excavation method for the diversion of the main canal through the Qinhe River. Pipe-jacking method and directional drilling method; Through further comparison and analysis, it is determined that the directional drilling scheme is the best scheme for crossing the Qinhe River. The results not only provide a reference for the design of river channel crossing which the integrity of section is not allowed to destroy, but also provide reference for the design of similar crossing engineering in the lower reaches of Qinhe River.
