Hole wall treatment device and method for cast-in-place pile
The invention relates to the technical field of cast-in-place piles, in particular to a cast-in-place pile hole wall processing device and method.The cast-in-place pile hole wall processing device comprises a drill rod, a steel casing, a patch mechanism and a feeding mechanism; when a drill rod drills a hole, the multiple hole wall protection pieces are sequentially laid on the inner wall of a pile hole below the steel pile casing layer by layer from shallow to deep by the piece pasting mechanism to form the protection layer, and according to the laying depth of the protection layer, the hole wall protection pieces are pasted on the inner wall of the pile hole. The multiple spring pieces are sequentially arranged on the inner sides of the hole wall protection pieces from top to bottom through the feeding mechanism and used for limiting the hole wall protection pieces at the same height on the inner wall of a pile hole. The protection layer formed by the multiple hole wall protection pieces can play a role in supporting the soil layer structure and preventing the soil layer from collapsing on the inner side of the hole wall so as to keep the stability of the pile hole structure, and compared with an existing slurry wall protection mode, the wall protection structure is higher in forming speed, stable in wall protection effect, capable of aiming at pile holes such as soft sandy soil layers and wider in application range.
本发明涉及灌注桩技术领域,具体而言涉及灌注桩的孔壁处理装置及方法,包括:钻杆、钢护筒、贴片机构和送料机构;在钻杆钻孔的同时,多个所述孔壁护片被所述贴片机构由浅至深逐层的依次铺设在所述钢护筒下方的桩孔内壁上形成所述防护层,并依据所述防护层的铺设深度,多个所述弹簧片由上至下依次被所述送料机构设置在所述孔壁护片的内侧,用于对桩孔内壁上同一高度的所述孔壁护片进行限位;多个孔壁护片形成防护层的可以在孔壁内侧起到支撑土层结构,防止土层塌落作用,以保持桩孔结构的稳定,相对于现有的泥浆护壁方式,护壁结构成型速度更快,且护壁效果稳定,能够针对松软的砂质土层等桩孔,用途更广。
