Abstract:
The present application discloses a final joint of an immersed tunnel, a prefabrication method and an installation method, wherein the final joint includes two end surfaces connected with installed adjacent tube sections; the two end surfaces are both tilted surfaces, so that the longitudinal profile of the final joint along an installation direction is of an inverted trapezoid structure; and the final joint further may be of a structure with a tube section I and a tube section II which are connected with each other. The final joint of the immersed tunnel is simple in structure, convenient to control and relatively high in precision, thereby reducing lots of open sea diving work and lowering a risk of installation quality defects; as prefabrication procedures are simple, the final joint may be prefabricated in a land factory and then transported to the site, thereby reducing influence of weather conditions on construction; a body structure of the final joint is prefabricated in the factory, and then the overall final joint is transported to the site for installation; water stop systems realize quick water stop, thus forming a dry construction environment; and therefore, the influence of weather and tidal current conditions on a project may be reduced, and a quality risk may be lowered.

Claim (Index 20):
The prefabrication method of the final joint of the immersed tunnel according to  claim 19 , wherein when the final joint includes a tube section I and a tube section II, the prefabrication method comprises:\n respectively forming a shell body of the tube section I and a shell body of the tube section II according to to-be-prefabricated shapes of the tube section I and the tube section II; installing the plurality of transverse diaphragms and longitudinal diaphragms in the shell body of the tube section I and the shell body of the tube section II to form the plurality of compartments; connecting the shell body of the tube section I with the shell body of the tube section II, and performing tensioning and compression through the prestressed tendons; pouring the concrete through the pouring holes in the shell body of the tube section I and the shell body of the tube section II, thus forming the tube section I and the tube section II, installing water stop systems on he connection surfaces respectively connected with installed adjacent tube sections of the shell body of the tube section I and the tube section II, thus completing prefabrication of the final joint of the immersed tunnel.
