Embodiment 4

[0048] Embodiment 4: a kind of construction method of novel TBM as described in embodiment 3, the steps are as follows:

[0049] S1: During the excavation process of the cutter head 2, the anchor drill splitting device 1 is retracted into the cutter head 2, and the opening and closing sealing device 3 is closed; that is, when the drilling machine is in the initial position, the anchor drill splitting device is installed in the axial direction of the cutter head inside the hole, such as Figure 7 shown;

[0050] S2: When the TBM is shutting down for support and segment assembly, the opening and closing sealing device 3 is opened, and the anchor drill splitting device 1 is driven forward by the sliding drive device 103 from the axial installation hole 202 of the cutter head 2 ;Such as Figure 8 shown;

[0051] S3: The anchor-drill device 101 of the anchor-drill splitting device 1 drills a hole on the face. After the drilling is completed, the splitting device 102 of the ancho...

Abstract

The invention discloses a novel TBM and a construction method thereof, and solves the problems of low driving efficiency and serious wear of a cutter head when the TBM excavates hard rock in the prior art. The present invention includes a driving machine and a supporting system. The driving machine includes a cutterhead connected to the main drive provided in the driving machine. Anchor drill splitting device for assisting rock breaking. The present invention integrates the functions of the anchor drilling rig and the hydraulic splitting rod. The anchor drilling device is used to drill holes on the face, and the splitting device expands and splits the drilled holes. Carry out hard rock drilling, and then the cutter head excavates the drilled face to reduce the wear of the excavation tool and improve the excavation efficiency.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a novel TBM and a construction method thereof. Background technique [0002] Rock tunnel boring machine (TBM) is a large-scale tunnel excavation equipment integrating mechanical, electronic, hydraulic, laser and other technologies. It plays an important role in the construction of mountain tunnels and urban subway projects. However, when encountering high-strength rocks, such as granite, marble, etc., the efficiency of TBM excavation decreases significantly, and the loss of tools is huge, and the construction cost increases. And existing excavation equipment such as application number is a kind of excavation anchor drill integrated hard rock roadheader of CN201410760991.3 and application number is a kind of composite splitting machine of CN201711130728.6 and can be used for the excavation of hard rock, but with existing The integration of TBM is poor. How to use anch...
