摘要
南水北调中线京石段临时通水过程中,个别渠道倒虹吸进出口扭坡渐变段发生沉降和后仰,造成止水拉裂,局部出现渗水现象。通过对沉降及伸缩缝止水等问题的进一步处理,提高了结构的抗渗性和耐久性。
In the progress of Beijing-shijiazhuang section midline South-to-North Water Transfer temporary through water,settlement and extension are found in individual inverted siphon export slope transition section,causing the water stopping and tension crack,local has the water seepage.Via the further treatment to the problems of settlement and the expansion joint,improving the anti-permeability and durability of the structure.
