Abstract

The invention discloses a pressurizing balance device for starting of a shield tunneling machine. The device comprises a sleeve, the shield tunneling machine is arranged in the sleeve, two sliding rods are symmetrically fixedly connected in the sleeve, each sliding rod is sleeved with a box body and slidingly connected with the box body, a driving mechanism is arranged in each box body, and a mounting block is fixedly connected with the end, away from the corresponding sliding rod, of each box body; two cavities are symmetrically formed in the sleeve, each cavity is internally provided with apushing mechanism, and two placing grooves are symmetrically formed in the sidewall of the sleeve; a fixing plate is arranged in each placing groove, and the end, away from the shield tunneling machine, of the sleeve is fixedly connected with a fixing base. The device is stable in structure, easy to operate, scientific and reasonable in design, short in production cycle, low in manufacturing costand easy to install and operate, and the shield tunneling machine is supported firmly and can be pressurized more stably so that the shield tunneling machine can move and work more smoothly.

Description

technical field [0001] The invention relates to the technical field of starting of a shield machine, in particular to a pressure balance device used for starting of a shield machine. Background technique [0002] A shield machine is a tunnel boring machine that uses the shield method. The construction method of shield tunneling is the "shield" (referring to the supporting segment) of the tunnel constructed (laid) by the tunnel boring machine at the same time as the excavation. It is different from the open construction method. Internationally, the generalized shield machine can also be used in rock formations , It is only different from the open (non-shield method) tunnel boring machine. In our country, it is customary to call the tunnel boring machine used in soft soil stratum (narrow sense) shield machine, and the one used in rock stratum is called (narrow sense) TBM. Shield, extrusion shield, semi-mechanical shield (local pressure, global pressure), mechanical shield (o...
