Abstract

The invention discloses a shielding tunneling machine drive box and a production method thereof. The shielding tunneling machine drive box is composed of a big flange 1, first rib plates 14, second rib plates 16, third rib plates 18, small flanges A 3, a ring A 4, a front cover plate 9, a ring B 10, cover plate supports 6, small flanges B 13, small flanges C 20, a cover plate 5, a ring C 2, a ring D 12 and fourth rib plates 7. The production method of the shielding tunneling machine drive box experiences repetitive tests to acquire optimal welding production orders, welding internal stress is reduced to the utmost and the purpose of controlling weld deformation through symmetrical welding mode of simultaneous operations by two welders and reasonable welding process rules on multiple welding positions easy to deform is achieved. By the production method, the problems that welding joints of massive forge pieces are exploded to crack during welding and the drive box suffers welding deformation during production are effectively solved.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a shield machine driving box and a manufacturing method thereof. Background technique [0002] The shield machine is a special construction machine for tunneling. According to the working principle, the shield machine is generally divided into hand-excavated shield, extrusion shield, semi-mechanical shield (local air pressure, global air pressure), mechanical shield (open chest cutting shield, pneumatic shield , Slurry pressurized shield, earth pressure balance shield, hybrid shield, shaped shield). [0003] The earth pressure balance shield machine uses the soil material (if necessary, add foam to improve the soil) as the medium to stabilize the excavation surface. A soil chamber is formed between the rear partition of the cutterhead and the excavation surface, and the cutterhead rotates to excavate. The soil material is increased, and then the soil material is tran...
