Longitudinal stress transfer test platform for disassembly and assembly of shield segment

Номер: CN116660040A
Принадлежит:

The invention provides a longitudinal stress transfer test platform for disassembly and assembly of shield segments. Comprising a front baffle plate, a rear baffle plate, a bottom base, four threaded connecting rods, an overlying structure, a loading heavy block, a first rubber gasket, a second rubber gasket, a loading device, a first movable force transmission baffle plate, a second movable force transmission baffle plate, a first extractable duct piece baffle plate and a second extractable duct piece baffle plate, a first overlying structure baffle and a second overlying structure baffle. The test platform is mainly used for obtaining the longitudinal mechanical behavior characteristics in the shield segment assembling and disassembling process. The research on the mechanical behavior characteristics of the duct piece is beneficial to optimization of the structural design of the duct piece tunnel, and has important guiding significance on shield assembly control.
