Between be provided with cushion；And two box beam end drawing pedestals are positioned and fastened by drawing bolt.
Preferably, reserved drawing bolt hole on described box beam end drawing pedestal.
Preferably, described rubber fastening band is arranged on the inner side of reserved drawing bolt hole.
Preferably, the cross-sectional area of described submerged tunnel box-beam structure is more than or equal to 12 square metres.
Preferably, the bottom of described box beam end drawing pedestal cooperates with the bottom；The described water surface is under water
, there is a certain distance at the top of tunnel box-beam structure between submerged tunnel box-beam structure and the water surface.
During present invention operation, tunnel line plane, vertical line type are fitted according to underwater topography and line requirements；According to
Circuit is flat, vertical line type, and tunnel box-beam structure is divided into some sections, and every section of box beam length can be not less than 120m；Box beam is indirect
Head nearby arranges pile foundation and supporting plate, and supporting plate top surface absolute altitude is identical with tunnel structure floor level；In construction pile foundation and supporting plate simultaneously,
Prefabricated tunnel box beam；End drawing pedestal is simultaneously prefabricated with box beam, form overall；Waterstop is arranged on the outside of drawing pedestal；
After box beam is lifted on underwater pile foundation, by drawing bolt prefabricated case beam drawing is connected to form tunnel.
After said structure, the present invention has the beneficial effect that：A kind of joint connection machine of submerged tunnel of the present invention
Structure, difficulty of construction is little, process is simple, speed of application are fast, low cost, it is to avoid problems of the prior art, is conducive to water
The operation of lower engineering.
