The invention relates to a city dense district large-section jacking pipe joint hoisting sling and a hoisting method thereof. The hoisting sling comprises a pair of box bodies and a connecting bolt. Lifting lugs are arranged at the tops of the box bodies, bolt holes are formed in the box bodies, and the pair of box bodies can be attached to the two opposite sides of the pipe joint to be hoisted; and the bolt holes in the box bodies are aligned with a hoisting hole in a pipe joint to be hoisted; The connecting bolt is inserted into the bolt holes of the box bodies, and the box bodies and the pipe joint to be hoisted are connected by penetrating the connecting bolt into the bolt holes and the hoisting hole. The hoisting sling is suitable for lifting large-section jacking pipe joints in urban dense areas, is small in size and convenient to manufacture and machine on site, is attached to the side parts of the pipe joints during use, is beneficial to hoisting in a narrow space, can be used for conveniently hoisting the pipe joints in smaller and shallower working wells as the hoisting sling is small in size and does not occupy space, and is capable of flexibly avoiding a structure and avoiding collisions with the structure.
本发明涉及一种城市密集区大断面顶管管节吊装吊具及其吊装方法,该吊具包括:一对箱体,顶部设有吊耳,所述箱体上设有插销孔,所述的一对箱体可贴设于待吊装的管节的相对两侧,且所述箱体上的插销孔与待吊装的管节上的吊装孔相对齐;供插设于所述箱体的插销孔内的连接插销,通过所述连接插销穿置于所述插销孔和所述吊装孔内以实现连接所述箱体和所述待吊装的管节。本发明提供的吊具适用于城市密集区的大断面顶管管节的吊装,该吊具尺寸小巧,便于现场制作加工,且使用时贴设在管节的侧部,利于狭小空间内的吊装,该吊具由于尺寸小,不会占用场地,能够便于在较小较浅的工作井内吊装管节,可灵活的避开结构避免与结构发生碰撞。
