Double-pile-casing structure for vertical shaft
The invention relates to the technical field of tubular pile construction, and particularly discloses a vertical shaft double-pile-casing structure which comprises an outer pile casing, an inner pile casing is arranged in the outer pile casing and comprises a first connector cylinder and a second connector cylinder, an inserting block is installed at the lower end of the first connector cylinder, and an inserting groove is formed in the inner side of the upper end of the second connector cylinder; a guide roller is arranged in the roller support, a ground breaking block is installed on the portion, located on the outer side of the second connector cylinder, below the guide roller, a lining rib is installed on the inner side wall of the outer protection cylinder, and a guide groove is formed in the lining rib. When the conical soil breaking block moves towards the interior of a soil body, the soil body in the lining ribs can be impacted and pushed, the perpendicularity of the inner pile casing is guaranteed under the guiding effect that the lining ribs and the guiding grooves are matched with the guiding rollers after the outer pile casing sinks, and the perpendicularity of the inner pile casing is guaranteed under the guiding effect that the lining ribs and the guiding grooves are matched with the guiding rollers after the outer pile casing sinks. And the perpendicularity of the inner pile casing can be effectively ensured.
本发明涉及管桩施工技术领域，具体公开了一种竖井双护筒结构，包括外护筒，外护筒的内部设置有内护筒，内护筒包括：第一接头筒、第二接头筒，第一接头筒的下端安装有插接块，第二接头筒的上端内侧开设有插接槽，滚轮支架的内部设置有导向滚轮，导向滚轮的下方位于第二接头筒的外侧安装有破土块，外护筒的内侧壁安装有内衬筋，内衬筋的内部开设有导向槽。锥形的破土块在向土体的内部移动时，可以实现对内衬筋内部的土体进行冲击推动，外护筒的下沉后利用内衬筋和导向槽配合导向滚轮的导向作用下，保证内护筒垂直度，外护筒的下沉后利用内衬筋和导向槽配合导向滚轮的导向作用下，可以有效的保证内护筒垂直度。
