Building pile foundation immersed tube bottom-expanding soil sampling device and bottom-expanding soil sampling method
The invention belongs to the technical field of pile hole construction, and particularly discloses a building pile foundation immersed tube bottom-expanding soil sampling device and a bottom-expanding soil sampling method. A drilling cylinder of the device is connected with a mounting cylinder through a connecting mechanism; arc-shaped hollow columns and a bottom plate are arranged at the lower end of the drill barrel, scrapers are arranged between the adjacent arc-shaped hollow columns, one ends of the scrapers are rotationally connected through rotating shafts I, and a plurality of scraping teeth are arranged at the other ends of the scrapers. A driving rod of a bottom expanding driving device arranged in a cavity I of the drill barrel is hinged to the scrapers. A mounting opening is formed in the end face of an arc-shaped hollow column of the removing mechanism, a moving plate is arranged in the arc-shaped hollow column and fixed to an arc plate, the other end of the moving plate penetrates through the mounting opening and extends to the position between scraping teeth, a crankshaft is rotationally arranged between the top wall of the arc-shaped hollow column and a bottom plate, and a crankshaft guide column penetrates through an arc plate guide groove in a sliding mode. And a gear pair is connected between a rotating shaft I connected with the scraper and the crankshaft. The method comprises the steps of device installation, expanded-base unfolding, expanded-base soil taking and folding and cleaning. The device has the characteristics of simple and reliable structure, high efficiency, convenience in adjustment and easiness in recovery.
本发明属于桩孔施工技术领域，具体公开一种建筑桩基沉管扩底取土装置及扩底取土方法。该装置的钻筒通过连接机构与安装筒连接；钻筒下端设有弧形空心柱及底板，相邻弧形空心柱间设有刮板，刮板一端通过转轴Ⅰ转动连接、另一端设有若干刮齿，钻筒空腔Ⅰ内设置的扩底驱动装置的驱动杆与刮板铰接；剔除机构的弧形空心柱端面开设有安装口，运动板设于弧形空心柱内且与圆弧板固定，运动板另一端穿过安装口延伸至刮齿间，弧形空心柱顶壁与底板间转动设有曲轴，曲轴导柱滑动贯穿圆弧板导槽，刮板连接的转轴Ⅰ与曲轴间连接有齿轮副。所述方法包括装置安装、扩底展开、扩底取土、收拢清理步骤。本发明具有结构简单可靠、效率高、调整便捷、易回收的特点。
