Taper spring sleeve-clamping sleeve connecting and assembling device for prefabricated parts of underground comprehensive pipe gallery

The invention provides a taper spring sleeve-clamping sleeve connecting and assembling device for prefabricated parts of an underground comprehensive pipe gallery, solving the problem that the space of the comprehensive pipe gallery is narrow, construction quality and construction efficiency are difficult to guarantee. A bottom plate (17), a top plate (15) and left and right wallboards (16) are connected to form the pipe gallery. The top plate and the bottom plate are of the same structure and symmetrical in the up-down direction. The top plate and the bottom plate are each formed by sequentially connecting a first prefabricated part, a second prefabricated part and third-n prefabricated part, wherein the structures of the third-(n-1) prefabricated parts are the same as the structure of the second prefabricated parts, and the n prefabricated part and the first prefabricated part are of the same structure and symmetrical in the left-right direction. The left wallboard and the right wallboard are each composed
