    • A plurality of agitation spindles are disposed, and an agitation vane is attached to the lower portion of each agitation spindle. A mixing and kneading zone for mixing and kneading soft soil with a hardener is formed so that the hardener is supplied near these agitation vanes. The agitation spindles are supported by reinforcing members and connecting members to construct a multiple spindle kneading apparatus for improving ground. In one embodiment, blade-like excavating cutters are mounted on the agitation spindles. In another embodiment, hollow agitation spindles are used and the hollow portions are used as hardener passages. In still another embodiment, a tube for injecting the hardener into the mixing and kneading zone is disposed so that it can be moved up and down. A method for hardening soft ground by using this multiple spindle kneading apparatus in which the hardener feed position can be changed is provided.
    • 设置多个搅拌轴,在搅拌轴的下部安装搅拌叶片。 形成用于将软土与硬化剂混​​合和捏合的混合和捏合区域,使得硬化剂在这些搅拌叶片附近供应。 搅拌轴由加强构件和连接构件支撑,构成用于改善地面的多主轴捏合装置。 在一个实施例中,叶片式挖掘刀具安装在搅拌轴上。 在另一个实施方案中,使用中空搅拌锭子,并且将中空部分用作固化剂通道。 在另一个实施例中,将用于将固化剂注入混合和捏合区域的管设置成使其能够上下移动。 提供了一种通过使用其中可以改变固化剂进给位置的该多轴捏合装置来硬化软土的方法。
