Embodiment

[0012] Figure 1 shows that a specific embodiment of the present invention is a tunneling guide device for a model shield machine, which consists of: a mirror 1 with a rearward mirror surface fixed on the body of the model shield machine, and the mirror 1 The mirror surface is perpendicular to the axis of the model shield machine; the laser source 2 is fixed behind the tunnel excavated by the model shield machine, and a whiteboard 3 is fixed between the laser source 2 and the reflector 1. There is an alignment hole 4 on the whiteboard 3, and the laser source 2 and the line connecting the center of the alignment hole 4 is perpendicular to the mirror surface of the mirror 1.

[0013] In this example, the reflector 1 is specifically installed on the earth bin partition 5 of the model shield machine. Because the central axis of the model shield machine is the central axis of the bearing of the cutter head 6, and the partition plate 5 of the soil bin is perpendicular to the bearing ...

Abstract

The invention relates to a tunneling guidance device of a model shield machine, which comprises a reflector (1) which is fixed on in the model shield machine body and is provided with a backward mirror surface, and the mirror surface of the reflector (1) is vertical to the axle of the model shield machine; a laser source (2) is fixed behind a tunnel (7) dug by the model shield machine, a white board (3) is arranged on the tunnel between the laser source (2) and the reflector (1), and the white board (3) is provided with a counterpoint hole (4). The connecting line between the laser source (2) and the counterpoint hole (4) is vertical to the mirror surface of the reflector (1). The convenient and real-time observation of the advancing direction of the model shield machine can be carried out through the device, thus providing a basis for the adjustment along the tunneling direction; the tunneling guidance device of a model shield machine also has the advantages of simple structure and convenient use.

Description

technical field [0001] The invention relates to a part of a model shield machine, in particular to a driving guide device of the model shield machine. Background technique [0002] Using model shield machine to carry out indoor model test is an important means to study the adaptability or influence of shield machine to formation. Some shield models are tested for the purpose of simulating the prototype part, such as the half-section model shield machine made by Japanese scholar Morin (1984), the muddy water model shield machine made by Kurihara Kazuo et al. (1989), Nomoto et al. (1999) The miniature shield machine device manufactured by Tongji University (2006) and the double-shell single-screw model shield machine, etc., these model shield machines do not use special guide devices due to their small size and short propulsion distance. The real shield machine has a special guidance system during the construction process, which is composed of laser total station, signal tran...
