塑性混凝土防渗墙是一种塑性墙体结构,具有一定的抗压强度和抗渗能力,有较低的弹性模量,并可人为地控制,抑制渗漏、管涌等。塑性混凝土防渗墙不仅能有效截断坝(土)体的渗透水流和降低坝(土)体中渗透坡降,还能承受一定的垂直和水平荷载,能适应周围坝(土)体变形、地基变形,大大减小墙体内应力,避免墙体开裂,且可节约水泥,降低工程防渗造价,效果显著。
Plastic concrete cutoff wall is a plastic wall structure, with a certain degree of compressive strength and impermeability, low modulus of elasticity, and can be artificially controlled to suppress leakage, piping and so on. Plastic concrete cutoff wall can not only effectively cut off seepage water flow of dam (earth) body and reduce seepage gradient in dam (earth) body, but also can bear certain vertical and horizontal loads and can adapt to the deformation of surrounding dam (soil) body. The foundation Deformation, greatly reduce the stress in the wall, to avoid cracking the wall, and can save the cement, reduce the seepage prevention cost, the effect is remarkable.
