Eccentric stirring shaft for dry spraying stirring pile
The invention discloses an eccentric stirring shaft for a dry spraying stirring pile, which is characterized by comprising a shaft, a lower stirring blade is arranged at the lower part of the shaft, and an eccentric stirring blade is arranged above the lower stirring blade, namely, the stirring blade is in an asymmetric form with different lengths on the outer side of the shaft. The problem that deep powder cannot be smoothly sprayed upwards is solved, deep cement powder can reach the upper portion through the eccentric spiral stirring blade type exhaust channel, and the depth of a formed powder spraying pile can reach more than 40 meters. Under the action of the stirring blades at the upper part, the powder is further stirred and is prevented from overflowing, so that the technical effects of pollution prevention and environmental protection are realized.
本发明公开了一种干喷搅拌桩用偏心搅拌轴，其特征是：包括轴，轴的下部设置下部搅拌叶，下部搅拌叶上方设置偏心形式的搅拌叶，即搅拌叶片在轴外侧呈长短不同的不对称形式。本发明解决了深部粉不能顺利喷上去的问题，通过偏心螺旋形搅拌叶形式排气通道，使深部水泥粉能到达上部，形成的粉喷桩深度可达40多米。通过上部搅拌叶的作用，既进一步搅拌，又阻止了粉的溢出，实现防止污染、环保的技术效果。
