Device for crushing slag at bottom of large-size pile hole after steel reinforcement cage is placed and slag crushing method
The invention discloses a device and method for crushing slag at the bottom of a large-size pile hole after a steel reinforcement cage is placed. The device comprises the steel reinforcement cage, a grouting guide pipe and a traction rope, and a barrel is suspended on the traction rope; a cross beam is arranged at the top of the barrel and is clamped into a bayonet of a first limiting ring of thegrouting guide pipe; a main motor is arranged in the barrel, and a rotating body is arranged at the lower end of an output shaft of the main motor; and the rotating body comprises an upper rotating disc and a lower rotating disc, and at least three groups of folding knives are circumferentially distributed between the two rotating discs. The method is characterized in that the grouting guide pipeand the slag crushing device descend, after a lower rotary disc cushion block of the device makes contact with the bottom, an upper rotary disc continues to descend, two elastic pieces conduct hard extrusion under the self weight of the grouting guide pipe and the device to cross a second limiting ring, and bent parts of the two elastic pieces are hooked and fixed to the second limiting ring; andat the time, the folding knives are vertically compressed to be transversely expanded, and an impeller-type knife face is formed. When the device and the method are used for constructing the large-size pile hole, large soil blocks at the bottom of the hole can be fully crushed after the steel reinforcement cage is lowered.
本发明公开一种放置钢筋笼后对大尺寸桩孔孔底碎渣的装置及方法，该装置包括钢筋笼、注浆导管和牵引绳，该牵引绳上悬吊有筒体；筒体顶部设有横梁，横梁卡入注浆导管第一限位环的卡口；筒体内设有主电动机，主电动机的输出轴下端设有旋转体；旋转体包括上转盘和下转盘，两个转盘之间周向分布有至少三组组折叠刀；该方法的关键在于：下降注浆导管和碎渣装置，当装置的下转盘垫块触底后，上转盘继续下降，使得两弹片在注浆导管和装置自重下硬挤越过第二限位环，两弹片的弯折部与第二限位环钩挂固定，此时，折叠刀由于竖向被压缩而横向扩开，形成叶轮式刀面。该装置及方法施工大尺寸桩孔时，能在下放钢筋笼后将孔底的大土块破碎充分。
