Embodiment Construction

[0008] The figure includes a tunnel boring machine head 1, which is characterized in that there is a connecting end 2 on the rear end surface of the tunnel boring machine head 1, and a jacked pipe joint socket device 3 or a shield assembly device 4 connected with the connecting end 2. The pipe joint socket device 3 is a pipe joint socket ring 5 . The shield assembly device 4 is composed of an oil cylinder jacking mechanism 10, an assembling mechanism 6 and a shield tail sealing mechanism 7. The above three mechanisms are installed in a housing 8, and the jacking cylinder 9 of the oil cylinder jacking mechanism 10 is located at the bottom of the housing 8. At the front, the assembly mechanism 6 is located in the middle of the housing 8, and the shield tail grouting sealing mechanism 7 is located at the rear of the housing 8. The front end of the housing 8 is connected to the connecting end 2 at the rear end of the tunnel boring machine head 1. The housing The rear end of the 8 ...

Abstract

The present invention relates to a top shield integrated tunnel borer which is characterized in that the back end of a tunnel borer head is provided with a connecting end face; and the connecting end face is connected with a top pipe joint socket and spigot device or a shield assembling device. The top pipe joint socket and spigot device is a pipe socket and spigot ring. The shield assembling device consists of an oil cylinder jacking mechanism, an assembling mechanism and a shield tail sealing mechanism, and the three mechanisms are installed in a casing. A jacking oil cylinder is arranged at the front part of the casing. The assembling mechanism is arranged at the middle part of the casing. The shield tail grouting sealing mechanism is arranged at the back part of the casing. The front end of the casing is connected with the back end of the tunnel borer head. The back end of the casing is connected with a tunnel liner. The top shield integrated tunnel borer has the advantages of being capable of realizing two purposes of one tunnel boring equipment and reducing the cost for purchasing the equipment of a tunnel construction unit greatly.

Description

technical field [0001] The invention relates to a tunnel boring machine, in particular to a top-shield integrated tunnel boring machine. Background technique [0002] At present, the mining method, shield tunneling method and pipe jacking method are usually used in the excavation construction of large underground tunnels in the world. The mining method is generally used in rocky geological conditions, and the cave is excavated by blasting, and then the inner wall is built in the cave. tunnel. The shield tunneling method or pipe jacking method is more suitable for the excavation construction of urban underground tunnels with soft ground conditions. The shield tunneling method construction is to use the tunneling head with a cutting cutter head to excavate, and use the assembly machine at the back of the tunneling head. The segmented lining is assembled into a ring-shaped lining circle, while the tunnel lining does not move after installation. In the front of pipe jacking co...
