Steel casing of seawall riprap layer rotary excavating pile machine and embedding construction method
The invention discloses a seawall riprap layer rotary digging pile machine steel casing, and relates to the technical field of steel casing embedding construction.The seawall riprap layer rotary digging pile machine steel casing comprises a rotary digging pile machine drill bit, a steel sleeve and a cast-in-place pile steel casing, a first clamping groove is formed in the lower end of the rotary digging pile machine drill bit, and a first buckle is installed at the upper end of the inner wall of the steel sleeve; a steel sleeve is installed at the lower end of the outer wall of the cast-in-place pile steel casing, a second buckle is installed at the lower end of the outer wall of the steel sleeve, a reinforcing steel hoop is arranged at the upper end of the cast-in-place pile steel casing, a second clamping groove is formed in the upper end of the reinforcing steel hoop, drilling teeth are arranged below the cast-in-place pile steel casing, and the cast-in-place pile steel casing and the drilling teeth are connected through a dismounting and mounting mechanism. By arranging the first clamping groove, the first buckle, the second clamping groove and the second buckle, the process from burying of the cast-in-place pile steel casing to hole forming can be completed only through one rotary excavating pile machine, frequent replacement of construction equipment is avoided, and the construction process is simplified; the detachable cast-in-place pile steel casing has the effect of being capable of being used repeatedly, and the construction cost is saved to a certain degree.
本发明公开了海堤抛石层旋挖桩机钢护筒，涉及钢护筒埋设施工技术领域，包括旋挖桩机钻头、钢套筒和灌注桩钢护筒，所述旋挖桩机钻头的下端开设有第一卡槽，所述钢套筒的内壁上端安装有第一卡扣，且所述钢套筒的外壁下端安装有第二卡扣，所述灌注桩钢护筒的上端设置有加强钢箍，所述加强钢箍的上端开设有第二卡槽，所述灌注桩钢护筒的下方设置有钻齿，且所述灌注桩钢护筒与所述钻齿之间通过拆装机构相连。本发明通过设置第一卡槽、第一卡扣、第二卡槽和第二卡扣，从灌注桩钢护筒埋设到成孔只用一台旋挖桩机就能完成，避免频繁更换施工设备，简化施工流程；可拆卸的灌注桩钢护筒，具有可重复利用的效果，在一定程度上节约了施工成本。
