Embodiment 1

[0033] like figure 1 It shows, a double -shield shell separation full section advanced pre -cracking tunnel excavator is divided into pre -cracking mode and excavation mode, including main engine connecting knife plate 1, separated inner shield case 4 and outer shield case. 2. Human cabin 5 and slide plates connected to the inner shield case 3, the expansion oil cylinder connected to the inner shield case 4 and the ring frame 96, the sliding support support 7 and the full section advance pre -cracking with the shield shell 2 Institutions 9. Track transport aircraft 10 of slag stones 10.

[0034] The inner shield case 4 and the outer shield case 2 are separated from each other. The shield shell 2 is used as the protective main body and protects the cabin room. The inner shield case 4 is used as the main body of the mobile module. Drives the knife plate 1 and the main engine 6 when the mode is switched.

[0035] The sliding support 7 is connected to the shield case 2, and the suppor...

Embodiment 2

[0042] A method of excavation method of a double -shield -separated full -section advanced pre -fissure tunnel excavator. The steps include:

[0043] (1) Check whether the telescopic oil cylinder Ⅰ8 and the telescopic oil cylinder II 92 can work normally, the drilling arm 91 and the supercritical mixed fluid storage room pipeline connection normally, the inner shield case 4 and the knife plate 1 angle; it needs to be guaranteed The telescopic cylinder Ⅰ8 and telescopic oil cylinder II 92 normal work, diamond arm 91 and supercritical mixed fluid storage room pipelines are connected normally, inner shield shells 4, and knife plate 1 angle is not tilted;

[0044] (2) By controlling the contraction of the telescopic cylinder Ⅰ8, the excavation machine is adjusted to a pre -fissure mode, that is, the mobile module containing knife tray 1. main engine 6 and the inner shield case 4 from the telescopic cylinder I8 move to the ring frame 96 until the four connections are connected until fo...

Abstract

The invention discloses a double-shield-shell separation type full-section advanced presplitting tunnel boring machine. The main engine (6) is connected with a cutter head (1), the inner shield shell (4) and the outer shield shell (2) are separated, the telescopic oil cylinder I (8) is connected with the inner shield shell (4) and an annular frame (96), the sliding support (7) is connected with the outer shield shell (2) and located between the outer shield shell (2) and the inner shield shell (4), the full-section advanced presplitting mechanism (9) is located on the annular frame (96), and the annular frame (96) is connected with the outer shield shell (2) and located behind the cutter head (1) in parallel. And the inner shield shell (4) is connected with a main engine (6). The invention further discloses a tunneling method of the double-shield-shell separation type full-section advanced presplitting tunnel boring machine. The problems that an existing tunnel boring machine is high in hob loss speed and hard rock tunneling is difficult are effectively solved.

Description

Technical field [0001] The present invention belongs to the field of underground engineering construction machinery and construction method, which involves a two -shield shell separation full section advanced pre -cracking tunnel excavator and its excavation method, especially involving a scalable double -shield shell separation full section ahead of advance Crack tunnel excavator and process method. Background technique [0002] The tunnel excavator is a mechanical for tunnel digging. The main means is to use roller knife to break the hard rocks. However, with the continuous development of tunnel digging technology, it is difficult to meet people's needs by simply using rolling rocks. Especially the high -hard rock tunnel, the wear of the rolling knife is greatly changed, which requires frequent swords, increasing economic costs, time costs, and danger. [0003] Although the current technology, although a variety of auxiliary methods are proposed to help the excavation machine f...
