Cast-in-place pile construction pile casing, construction method and cast-in-place pile formed through method
The invention discloses a cast-in-place pile construction pile casing, a construction method and a cast-in-place pile formed through the method, the pile casing comprises two arc-shaped steel plates and two V-shaped steel plates, the straight edges of the arc-shaped steel plates are welded to the bottom edges of the corresponding corners of the two V-shaped steel plates respectively, and the two V-shaped steel plates are oppositely located on the outer sides of the arc surfaces of the two arc-shaped steel plates to define a barrel wing-shaped steel pile casing; when the pile casing is erected, horizontal projections of the two arc-shaped steel plates are concyclic, the radius of the two arc-shaped steel plates is the same as that of a designed cast-in-place pile body, and the arc-shaped steel plates and the V-shaped steel plates are symmetrically arranged. Triangular steel plates are hinged to the side edges of the two corners of the lower end of the V-shaped steel plate correspondingly, can be rotationally closed to form a pointed end when the pile casing is pressed into soil and can be rotationally opened when the pile casing is pulled out of pile body concrete; and during closing, the arc-shaped edge of each triangular steel plate and the horizontal projection of the two arc-shaped steel plates form a circle with the same radius as the body. The pile casing is similar to a conventional cylindrical steel pile casing and can be repeatedly used, wing plates are conveniently formed on the two sides of the upper portion of the body, and therefore the horizontal bearing capacity of the cast-in-place pile is improved.
本发明公开了灌注桩施工护筒、施工方法及采用该方法成型的灌注桩，该护筒包括两片弧形钢板和两片V型钢板，弧形钢板的直边分别与两片V型钢板相应角底边焊接、且两片V型钢板相对位于两片弧形钢板的弧面外侧，围成筒翼状钢护筒；护筒竖立时，两片弧形钢板水平投影共圆且半径与设计的灌注桩本体半径相同，弧形钢板、V型钢板均对称布置；V型钢板下端两条角侧边分别铰接三角形钢板，其在护筒压入土中时可转动闭合成尖头，在护筒拔出桩体混凝土时可转动张开；且闭合时各三角形钢板的弧形边及两片弧形钢板的水平投影呈与本体半径相同的圆形。本护筒实施与常规圆筒型钢护筒类似并可重复使用，方便在本体上部两侧形成翼板，从而提高灌注桩水平承载力。
