本文在总结倒虹吸设计和施工经验的基础上,提出加长管节长度,减少接头;增加垂直渗迳长度,以减少土壤渗透变形和增设盲沟以利排除渗水等三项建议,用以改进倒虹吸设计。 文中介绍了倒虹吸的纵向受力计算、水力计算等问题,还提出了一种经济合理的新型倒虹吸即断面为内圆“外城门”型(内圆外马蹄型)倒虹吸;并附倒虹吸水力计算和倒虹吸纵向受力计算算倒。
Based on the summarization of the design and construction experience of inverted siphon, this paper proposes three suggestions: to increase the length of pipe joints and reduce the joints; to increase the length of vertical infiltration so as to reduce soil infiltration and deformation and to create blind ditches to eliminate water seepage; Siphon design. In this paper, the problems of longitudinal force calculation and hydraulic calculation of inverted siphon are introduced, and a new type of inverted siphon which is economical and reasonable is proposed, ie, the inner circle “outer gate” type (inner and outer horseshoe) inverted siphon is adopted. Inverted siphon hydraulic calculation and inverse siphon longitudinal force calculations count down.
