Abstract

The invention discloses a cable installation connection structure of a shield tunneling machine power system and a connection method thereof. The shield tunneling machine power system comprises a ground power supply system, a shield power distribution system and a cable, wherein a relay box is arranged on an annular pushing iron or a pushing system, the cable is divided into a fixed part cable anda movable part cable, one end of the fixed part cable is connected with the ground power supply system, the other end of the fixed part cable is connected with the wire inlet end of the relay box, one end of the movable part cable is connected with the wire outlet end of the relay box, and the other end of the movable part cable is connected with the shield power distribution system. According tothe structure and the method, through the addition of the relay box, on the basis of meeting the safety power utilization specification, the whole original cable is broken into two parts, so that after a section of pipe joint is finished in the tunneling construction, only the cable in the finished pipe joint of a tunnel needs to be disconnected with the wire outlet end of the relay box, the installation and positioning of a next pipe joint can be met, the connection of the construction process is improved, and the smooth tunneling of a rectangular shield tunneling machine is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a cable installation and connection structure and a connection method for an earth pressure balance rectangular shield top excavator power system mainly aimed at sand and pebble formations. Background technique [0002] With the rapid development of urban construction, the demand and requirements for the construction of urban underground space are also constantly increasing. The traditional underground engineering construction technology can no longer meet the needs of the construction of the central urban area. It is replaced by the rapid development of trenchless technology, including Rectangular shield top digging technology. [0003] The earth pressure balance rectangular shield top excavation method is a new construction technology with earth pressure balance top excavation as the core, combined with the characteristics of shield construction and pi...
