Splicing rotary drilling type steel casing
The invention relates to the technical field of rotary drilling pile machine construction, in particular to a splicable rotary drilling type steel casing which is characterized in that a steel casing rotating joint is connected to a spliced steel casing in a sliding manner, and the spliced steel casing is connected between the steel casing rotating joint and a bottom section steel casing in a sliding manner; a drill rod of the rotary drilling machine is inserted into the upper end of the steel casing rotary joint; the steel casing rotating joint comprises a trapezoidal steel plate, a circular steel plate, an upper steel casing and a connecting square groove, the trapezoidal steel plate is fixed on the circular steel plate, and the circular steel plate is fixed on the upper steel casing; a plurality of tenons are uniformly fixed on the outer wall of the upper steel casing; the steel casing has the beneficial effects that the tenon structure is adopted, so that the steel casing can be quickly assembled, transported and joined, and the construction efficiency and convenience are improved.
本发明涉及旋挖桩机施工技术领域，更具体的说涉及一种可拼接的回转钻进式钢护筒，包括钢护筒旋转接头通过滑动连接在拼接钢护筒上，拼接钢护筒通过滑动连接在钢护筒旋转接头和底节钢护筒之间；钢护筒旋转接头的上端插接旋挖机的钻杆；所述的钢护筒旋转接头包括梯形钢板、圆形钢板、上钢护筒和连接方槽，梯形钢板固定在圆形钢板上，圆形钢板固定在上钢护筒上；上钢护筒的外壁均匀固定有多个榫头；本发明的有益效果为采用卡榫结构能够快速进行钢护筒的组装、运输和衔接，以提高施工效率和便捷性。
