Connection channel tunnel boring machine and connection channel construction method

Abstract

The invention discloses a connection channel tunnel boring machine and a connection channel construction method. The connection channel tunnel boring machine comprises a tunnel boring machine body, a tunneling tool, a cutting tool, a rotation driving device and a sliding driving device; the rotation driving device is connected with the cutting tool so as to drive the tunneling tool to rotate around the axis of the tunnel boring machine body; and the sliding driving device is connected with the tunneling tool so as to drive the tunneling tool to move in the axial direction of the tunnel boring machine body. By applying the tunnel boring machine, segment cutting and soil body tunneling are conducted through the cutting tool and the tunneling tool respectively, segments at the starting end can be directly smashed and broken through the tunneling tool at the starting end, and manual assistance is not needed for removing the broken segments; the reinforced concrete segments are cut through the cutting tool at the receiving end, so that the problem that the segments are difficult to break and remove quickly due to the fact that the main tunnel segments at the receiving end are in reverse arc contact with a cutter head is solved; the tunneling tool is driven by the sliding driving device to move and crush in a small range in the tunneling direction; and the tunneling range of the tunneling tool is increased.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, and more specifically, relates to a tunnel boring machine for a communication channel, and also relates to a construction method for the communication channel. Background technique [0002] The communication channel is usually set between the two-line tunnels and connects the two main tunnels to meet multiple needs such as post-service, risk avoidance, and rescue. The construction methods used in the traditional communication channel construction mainly include freezing method construction and grouting reinforcement method construction. The above methods all need to reinforce the ground, stop water, and then use manual excavation. The settlement control is complicated and the construction efficiency is low. , high cost, long construction period, and low safety of construction personnel. [0003] For this reason, the prior art has occurred the communication channel shield / pipe jacking...
