摘要
沉井依靠自重消除刃脚阻力和外壁摩擦力下沉,本文对该项工艺的下沉、纠偏、挖土、封底主要技术问题进行介绍。
Sunk well depends on the gravity which eliminates the resising force at its bottom blade and the friction force of its external wall. In this artcle, the author states main technological problems of sinking, viation rectifying, soil diging and bottom seal.
