The root of placing boom section I is hinged to the upper slewing section by shaft I, and the end of placing boom section I is hinged to the root of placing boom section II by shaft II. One end of piston cylinder I is hinged to placing boom section I (or placing boom section II), and the other end is connected to placing boom section I and placing boom section II respectively through a linkage mechanism I. Concrete conveying pipe I and concrete conveying pipe II are respectively installed on placing boom section I and placing boom section II along their respective boom length directions by brackets.
