Stirring pile construction equipment with novel stirring blades
The invention provides stirring pile construction equipment with novel stirring blades. A drill rod is arranged on a pile frame, drill rod blades are arranged on the lower portion of the drill rod, and the stirring blades are arranged between the drill rod blades and connected with the drill rod through a rotatable shaft sleeve. During construction, the drill rod drills downwards, after being inserted into soil, the stirring blades do not rotate under the action of resistance, the drill rod blades continue to rotate under driving of the drill rod, the stirring blades and the drill rod blades move relatively to generate a cutting effect, and undisturbed soil is stirred into fine particles to be fully mixed with a curing agent; and when bonding soil blocks are bonded to the drill rod blades and the roots of the drill rod blades, the stirring blades and the drill rod blades move mutually, the bonding soil blocks of the drill rod blades can be removed, and the phenomenon that the blades are wrapped by the soil blocks is eradicated.
本发明提供一种带有新型搅拌叶片的搅拌桩施工设备，桩架上设置有钻杆，钻杆下部设有钻杆叶片，钻杆叶片之间设置有搅拌叶片，搅拌叶片通过可旋转轴套连接钻杆。施工时，钻杆下钻，搅拌叶片插入土体后，受到阻力作用不转动，而钻杆叶片在钻杆的带动下继续转动，搅拌叶片与钻杆叶片相对运动，产生切削作用，使的原状土搅碎成细颗粒与固化剂充分混合；当钻杆叶片上及其根部黏结有黏结土块时，搅拌叶片与钻杆叶片相互运动，可以清理掉钻杆叶片黏结土块，杜绝土块包裹叶片的现象。
