Construction method of inverted siphon pipeline
The inverted siphon pipeline construction method comprises the following steps that a first inverted siphon well is excavated on one side of an obstacle, and a second inverted siphon well is excavated on the other side of the obstacle; a drill bit of the drilling machine drills into the ground from the upstream of the first inverted siphon well, penetrates through the first inverted siphon well, penetrates through the lower portion of the obstacle, penetrates through the second inverted siphon well and drills out of the ground from the downstream of the second inverted siphon well; a drill bit of the drilling machine is replaced with a reamer, the reamer moves along the track of the drill bit, and a channel used for laying a first pipeline, a second pipeline and a third pipeline is formed underground; the second pipeline is pulled into the channel, and the two ends of the second pipeline are made to communicate with the first inverted siphon well and the second inverted siphon well correspondingly; the first pipeline is connected to the upstream of the first inverted siphon well, the water outlet end of the first pipeline is communicated with the first inverted siphon well, the third pipeline is connected to the downstream end of the second inverted siphon well, the water inlet end of the third pipeline is communicated with the second inverted siphon well, and according to the inverted siphon pipeline construction method, obstacles do not need to be damaged, and the construction influence is small.
本申请公开了一种倒虹吸管道施工方法，其包括如下步骤：在障碍物的一侧开挖第一倒虹井，在障碍物的另一侧开挖第二倒虹井；钻机的钻头从第一倒虹井的上游钻入地下，穿过第一倒虹井，从障碍物的下方穿过，穿过第二倒虹井，从第二倒虹井的下游钻出地面；将钻机的钻头更换为扩孔器，扩孔器沿着钻头的轨迹运动，在地下形成用于敷设第一管道、第二管道和第三管道的通道；将第二管道牵引至通道中，使第二管道的两端分别于第一倒虹井和第二倒虹井相连通；在第一倒虹井的上游接入第一管道，第一管道的出水端与第一倒虹井相连通，在第二倒虹井的下游端接入第三管道，第三管道的入水端与第二倒虹井连通，该倒虹吸管道施工方法无需破坏障碍物，施工影响少。
