Abstract

The invention belongs to the technical field of tunnel construction equipment, and relates to a shield tunneling machine for a tunnel connecting passageway and a connecting passageway tunneling method of the shield tunneling machine. The shield tunneling machine comprises a start end supporting walking platform and a receiving end supporting walking platform which are respectively arranged on material transportation rails in two main tunnels, a shield tunneling machine main unit, a counterforce supporting frame and a main tunnel supporting assembly which are respectively arranged on the start end supporting walking platform and a corresponding main tunnel duct piece, and a start end socket sealing assembly and a receiving end socket sealing assembly which are respectively arranged at the start end and the receiving end of the connecting passageway, wherein a duct piece hanging assembly is arranged on the start end supporting walking platform; a jacking tunneling assembly is arranged between the counterforce supporting frame and the shield tunneling machine main unit. The shield tunneling machine can realize automatically mechanical excavation; the labor intensity is greatly reduced, the energy consumption is reduced, and the cost is reduced; meanwhile, equipment construction is stable, and the efficiency is high; settling of the ground is effectively controlled, and the construction risk is reduced.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and in particular relates to a shield machine for a tunnel communication passage and a method for driving the communication passage. Background technique [0002] Under normal circumstances, subway tunnels or railway tunnels are double-line tunnels, and the distance between the two tunnels is relatively short. A communication channel needs to be designed at a certain distance between the tunnels to meet multiple needs such as later services and risk avoidance. The traditional communication channel construction is carried out by means of ground reinforcement, water sealing and manual excavation. Due to the complex settlement control, high safety risk, low construction efficiency and high cost, it is urgent to find a safe, reliable and economical mechanized and intelligent equipment to complete the construction of the communication channel. [0003] The shield machine is a hi...
