Stirring grouting head, cement-soil stirring pile device and construction method of cement-soil stirring pile device
The invention belongs to the field of cement-soil mixing pile devices, and particularly relates to a mixing grouting head, a cement-soil mixing pile device and a construction method of the cement-soil mixing pile device, and the mixing grouting head comprises a rod body, a drill bit, a mixing assembly and a grouting structure; the drill bit is arranged at one end of the rod body; the rod body is provided with a forward-rotation paddle conveying channel and a reverse-rotation conveying channel; the stirring assembly comprises grouting stirring blades arranged in an annular array along the axis of the rod body, and the forward grouting structure comprises a forward grouting channel formed in the lower end face of one grouting stirring blade and a forward side wall grouting hole formed in the side wall of the rod body. The reverse grouting structure comprises a reverse grouting channel formed in the lower end face of one grouting stirring blade and a reverse side wall grouting hole formed in the side wall of the rod body. The construction efficiency is improved, the construction time is shortened, and the grouting channel and the grouting hole of the stirring grouting head cannot be blocked by pressure while the lifting burden of the piling drilling machine is reduced.
本发明属于水泥土搅拌桩装置领域，具体是涉及到一种搅拌注浆头、水泥土搅拌桩装置及其施工方法，其中搅拌注浆头，包括杆体、钻头、搅拌组件和注浆结构；所述钻头设置在杆体的一端；所述杆体设置有正转输桨通道和反转输送通道；所述搅拌组件包括沿杆体轴线呈环形阵列设置的注浆搅拌叶，所述正转注浆结构包括设置在一个注浆搅拌叶下端面的正转注浆通道以及设置在杆体侧壁的正转侧壁注浆孔，所述反转注浆结构包括设置在一个注浆搅拌叶下端面的反转注浆通道以及设置在杆体侧壁的一个反转侧壁注浆孔。本发明提高施工了效率，缩短了施工时间，在降低对打桩钻机升降负担的同时，使得搅拌注浆头其注浆通道和注浆孔都不会受到压力造成堵塞。
