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。
In order to select the best Yellow River diversion project for diversion through the Qinhe River through the Qinhe River project, through analyzing the construction conditions of crossing the Qinhe River, crossing the building selection factor and the main crossing type, it is put forward that the water diversion canal crossing the Qinhe River is technically feasible Digging method, pipe jacking method and directional drilling method through three programs; through further comparative analysis to determine the directional drilling program is the best through the Qin River program. The results of this study not only provide reference for the design of river channel crossing which the integrity of the section does not allow to be destroyed, but also provide reference for the similar crossing engineering design of the lower reaches of the Qinhe River.
