Embodiment 1

[0056] like Figure 5 , Image 6 and Figure 7 As shown in the figure, a motorized TBM in this embodiment is used in a tunnel with a tunnel length of 1 to 2 km and relatively broken surrounding rock. According to this application environment, the corresponding integrated modules corresponding to the selected rear supporting trolleys are hydraulic power modules. 201 , support module 202 , dust removal equipment module 203 , electrical system module 204 , main control room lounge module 205 , secondary fan and water and electricity reel module 206 , tail slag removal module 207 . The optional hydraulic power module 201 is mainly to provide power for the propulsion of the excavation system of the main engine 10; the selection of the support module 202 is mainly to adapt to the situation that the surrounding rock of the tunnel is relatively broken, and to carry out initial support for the tunnel to ensure construction safety; to choose the dust removal equipment module 203 The m...

Embodiment 2

[0058] In this embodiment, as Figure 8 and Figure 9 As shown in the figure, a mobile TBM in this embodiment is used in a tunnel with a tunnel length of 1 to 2 km and a relatively complete surrounding rock. According to this application environment, the difference from Embodiment 1 is that the corresponding selected The integrated modules corresponding to the rear supporting trolleys are hydraulic power module 201 , dust removal equipment module 203 , electrical system module 204 , main control room lounge module 205 , secondary fan and hydropower reel module 206 , and tail slag removal module 207 . Since the surrounding rock is relatively complete, no support operation is required, so the support module 202 is canceled.

Embodiment 3

[0060] In this embodiment, as Figure 10 and Figure 11 As shown in the figure, a motorized TBM in this embodiment is used in a tunnel with a length of 100 to 300 m and a relatively broken surrounding rock. According to this application environment, the difference from Embodiment 1 is that the corresponding selected The integrated modules corresponding to the rear supporting trolleys are the hydraulic power module 201 , the support module 202 , the electrical system module 204 , and the tail slag removal module 207 . Due to the short length of the tunnel, the natural wind at the entrance of the tunnel can blow into the tunnel, and the air circulation in the tunnel is relatively good, so the dust removal equipment module 203 is cancelled; due to the short distance required for signal transmission, the optical fiber or wireless signal is stable without delay, TBM Remote operation and monitoring can be used, and the main control room can be placed directly outside the cave, so t...

Abstract

The invention relates to a TBM, in particular to a motorized TBM and a TBM construction method. The motorized TBM comprises a main machine and a rear matching system arranged behind the main machine, the rear matching system comprises a rear matching trolley, auxiliary equipment and a rear matching belt conveyor, the auxiliary equipment is arranged on the corresponding rear matching trolley in the form of an equipment module, and the corresponding rear matching trolley forms a modularized trolley; the modularized trolley is provided with a connector for connecting auxiliary equipment on the modularized trolley with external equipment so as to realize conduction of a circuit and / or a liquid path; each modular trolley is provided with an independent single-section belt conveyor, and the rear matched belt conveyor is formed by sequentially connecting the single-section belt conveyors arranged on the modular trolleys. The problems that in the prior art, a TBM is low in disassembly and assembly efficiency and poor in universality under the scene that the tunneling distance is short and the transition frequency is frequent can be solved.

Description

technical field [0001] The present invention relates to TBM, in particular to a mobile TBM and a TBM construction method. Background technique [0002] TBM (Tunnel Boring Machine, full-section boring machine) is a boring machine suitable for rock tunnels, widely used in municipal construction, transportation construction and other fields. TBM generally includes main engine and rear supporting system in structure. The main engine is mainly composed of cutter head, shield, propulsion system, main beam, main machine belt conveyor, etc. The rear supporting system mainly consists of the rear supporting trolley and is arranged on the rear supporting trolley. of auxiliary equipment. The rear supporting trolley is generally connected in sequence by the ear seat and the connecting rod, and is pulled by the main engine and moves forward with the main engine; auxiliary equipment includes hydraulic power station, power distribution equipment, cable reel, water pipe reel, dust removal a...
