Hole collapse prevention construction method for large-diameter pile foundation in full sand layer
The invention belongs to the technical field of building construction, and particularly relates to a full-sand-layer large-diameter pile foundation hole collapse prevention construction method which comprises the steps that S4, after reinforcement is completed, a rotating shaft is driven to drive a static pressure detection mechanism to move downwards by a certain distance, and the static pressure detection mechanism is driven to move downwards by a certain distance; the open water cleaning mechanism is located on the previous layer of the static pressure detection mechanism, so that the open water cleaning mechanism can absorb and scrape off the open water on the side wall of the hole under the rotation of the rotating shaft. According to the hole collapse prevention construction method for the full-sand-layer large-diameter pile foundation, through the arrangement of the open water cleaning mechanism, open water generated in the drilling process of the side wall of the hole is conveniently scraped off and absorbed, the guniting efficiency is improved, then the side wall of the hole is reinforced, and hole collapse is prevented; and meanwhile, the threaded sleeve is in threaded connection with the concave sleeve and the threaded telescopic sleeve to drive the elastic clamping pipe to clamp the connecting column, so that the concave scraping plate and the water absorption sponge are conveniently installed on the sleeve through the threaded sleeve, and disassembly and replacement are convenient.
本发明属于建筑施工技术领域，尤其是一种全砂层大直径桩基防塌孔施工方法，所述全砂层大直径桩基防塌孔的施工方法包括：S4、加固完成后，驱动旋转轴带动检测静压机构向下移动一段距离，使得明水清理机构位于检测静压机构此前在的那一层，便于明水清理机构在旋转轴的转动下将孔洞侧壁上的明水进行吸收和刮掉。该全砂层大直径桩基防塌孔施工方法，通过设置明水清理机构，便于将孔洞侧壁在钻孔过程中产生的明水刮掉和吸收掉，提高喷浆效率，进而加固孔洞侧壁，防止孔洞塌方，同时通过螺纹套与凹形套和螺纹伸缩套的螺纹连接带动弹力夹管夹持连接柱，从而便于通过螺纹套使得凹形刮板和吸水海绵安装在套管上，且便于拆卸更换。
