Abstract:
Disclosed are a construction ship for an underwater tunnel and a construction method therefor. The construction ship is composed of a rear section (1), a middle section (2) and a front section (3), the upper part of the construction ship being higher than water level, wherein the rear section (1) is both a sealing and water-blocking section of the construction ship and a tunnel and also a concrete casting section, when blocking water, for preventing water from entering the middle section (2) from a tunnel and a rear part seam, such that concrete fills a space between a base slab and two side slabs of a tunnel and rock and earth, and the cross section of a tail end opening is the same as the cross section of a tunnel tube section; the middle section (2) is a tunnel construction section, for performing tube section construction at a rear part cabin of the middle section (2), and connecting to an originally constructed tube section; a jacking apparatus (2-1) is mounted at a front part of the middle section (2); and the front section (3) is a rock and earth excavating section. The amount of earthwork excavation of the construction ship is low, since the front section of the construction ship excavates the rock and earth in a half-open U-shaped cabin (3-1), construction is convenient, and since two side walls of the U-shaped cabin (3-1) act to support the foundation; pit, the amount of earthwork excavation is low; construction is fast and safe and all construction operations are completed in the construction ship.
