Problems solved by technology

However, if the laser target is installed on the front shield, the position and orientation of the front shield will be measured during the excavation of the curved tunnel. Due to the influence of the measurement channel, the laser line of the total station is easily blocked, and the laser of the total station cannot reach the laser of the front shield. Therefore, the attitude of the front shield cannot be obtained, which affects the accuracy of the position and attitude data of the front shield and the quality of the tunnel construction.

Abstract

The invention discloses a double-shield position detection device. The device comprises a laser, a light sensing target and a controller; the laser is installed on the front end surface of a tight supporting shield; the light sensing target is installed on the rear end surface of a front shield; a shooting device is arranged in the light sensing target; laser light emitted by the laser comes to the light sensing target; and the laser and the shooting device are connected with the controller. According to the double-shield position detection device, the laser is arranged on the front end surface of the tight supporting shield, and the light sensing target is arranged on the rear end surface of the front shield; and when a double-shield TBM is used for curved tunneling, a light spot image isshot and processed through the shooting device arranged in the light sensing target, and a light spot offset of the rear end of the front shield is obtained, so that horizontal and vertical offsets of the front shield are obtained, and the accuracy of data is improved. In addition, the invention further provides a double-shield position detection method adopting the double-shield position detection device, a double-shield guide system and a double-shield guide method adopting the double-shield guide system.

Description

technical field [0001] The application relates to the technical field of tunnel engineering, in particular to a double shield position detection device, a double shield position detection method using the double shield position detection device, a double shield guidance system and a double shield guidance system The double shield guide method. Background technique [0002] Double-shield TBM (Tunel Boring Machine) is a kind of full-face hard rock tunnel boring machine, which generally consists of cutter head, front shield, telescopic shield, tension shield, tail shield, assembly system, belt conveyor, rear supporting parts, etc. composition. With the rapid development of the urban underground construction and the rail transit industry, the double-shield TBM can increase the excavation speed and apply to a wide range of rock formations, so it has been rapidly promoted and used. [0003] At present, the guidance system used for TBM at home and abroad is mainly composed of fou...
