Sludge in-situ curing method and in-situ curing stirring device
The invention provides a sludge in-situ curing method and an in-situ curing stirring device, and the method comprises the following steps: draining: draining water in a whole construction area; the whole construction area is divided into a plurality of areas, and the surface layer of a part of the areas is dredged so that the surface elevation of the part of the areas can be reduced; adding a curing agent into the sludge in each area and stirring to realize in-situ curing of the sludge; the ground of each area is solidified to the set elevation, and if the elevation is insufficient, backfilling slag is used for filling to the set elevation; in-situ solidification construction of the sludge is completed through the steps. T-shaped spiral blades are arranged on the outer wall of the stirring rotary drum and comprise blades perpendicular to the stirring rotary drum, transverse blades are arranged at the top ends of the perpendicular blades, arc-shaped spiral blades are arranged at the connecting position of the stirring rotary drum and the stirring head, and a plurality of overturning spiral blades are arranged at the free end of the stirring rotary drum. The structure can improve the mixing effect of the curing agent.
本发明提供一种淤泥原位固化方法及原位固化搅拌装置，包括以下步骤：排水，将整个施工区域的水排干；将整个施工区域划分为多个区域，将其中部分区域的表层清淤，以使该部分区域的表面高程降低；在各个区域的淤泥中添加固化剂并搅拌，实现淤泥原位固化；将各个区域的地面固化至设定标高，标高不足的，以回填渣填充至设定标高；通过以上步骤完成淤泥原位固化施工。在搅拌转筒的外壁设有T型螺旋叶片，T型螺旋叶片包括与搅拌转筒垂直的叶片，在垂直叶片的顶端设有横向叶片，在搅拌转筒与搅拌头连接的位置设有弧形螺旋叶片，在搅拌转筒的自由端设有多个翻转螺旋叶片。该结构能够提高固化剂的混合效果。
