Problems solved by technology

When the construction period is tight, there are also situations where the shield tunnel and the communication channel are excavated at the same time. The soil inside the tunnel communication channel needs to be manually transferred to the outside of the tunnel communication channel opening. The transfer rate is low, which seriously affects the excavation of the tunnel communication channel. efficiency

Abstract

The embodiment of the invention provides a soil body transfer method for a tunnel connection channel. A belt conveyor is adopted for operation, and the belt conveyor comprises a first belt conveyor. the soil body transfer method for the tunnel connection channel comprises the following steps that an upper step of the tunnel connection channel is excavated; the first belt conveyor is placed on theupper step formed by the tunnel connection channel; the soil body of the upper step is placed on the first belt conveyor; and the first belt conveyor is started, and newly excavated soil of the upperstep is conveyed out of an opening of the tunnel connection channel. A constructor places the soil body generated by excavating the upper step on the first belt conveyor, and conveys the soil body outof the opening of the tunnel connection channel by operating the first belt conveyor. Along with excavation of the upper step of the tunnel connection channel, the generated soil body is directly transported out of the opening of the tunnel connection channel, the soil body cannot remain in the tunnel connection channel, the transfer speed is high, and thus the excavation efficiency of the tunnelconnection channel is improved.

Description

technical field [0001] The invention relates to a tunnel excavation method, in particular to a soil transfer method for a tunnel connecting passage. Background technique [0002] At present, with the rapid development of urban rail transit, shield construction has gradually become the main construction method of urban subway construction. In order to meet the requirements of emergency evacuation and water collection and drainage in the section, tunnel communication passages are set between the left and right lines of the section, and pump rooms are installed inside some tunnel communication passages. The connecting channel of the shield tunnel is set in the middle of the two tunnels. After the construction is completed, it will become a channel between the two tunnels, which will play the roles of communication, drainage and fire prevention. If there is a problem in one tunnel as a whole, pedestrians can transfer to another tunnel through the connecting passage, and the saf...
