Abstract

The invention belongs to the technical field of tunnel construction equipment. A shield machine for a tunnel communication channel and its excavation method for the communication channel, comprising a supporting walking platform at the starting end and a supporting walking platform at the receiving end respectively arranged on the material transportation rails in two main tunnels, a shield machine host, and The starting end supports the walking platform and the corresponding reaction force support frame and main tunnel support assembly on the main tunnel segment, and the starting end seal assembly and the receiving end end seal assembly are respectively arranged at the starting end and the receiving end of the communication channel As for the sealing component, a segment hoisting component is set on the supporting walking platform at the originating end, and a jacking driving component is set between the reaction support frame and the main body of the shield machine. The invention can realize automatic and mechanized excavation, greatly reduces labor intensity, reduces energy consumption, saves cost, and at the same time, its equipment construction is stable and efficient, effectively controls ground subsidence, and reduces construction risks.

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...
