Abstract

The invention discloses a shield machine guiding system, in particular a shield machine double laser target guiding system, said guiding system comprising: a moving laser target is fixedly connected to a middle shield of a shield machine, and a fixed laser target is fixedly connected to a tunnel segment , The laser total station is fixedly connected with the back of the shield, and the computer contains coordinate calculation software. Adopting the technical scheme of the patent of the present invention, based on the earth coordinates of the fixed laser target, the earth coordinates of the laser total station are calculated with the help of a computer, and then the earth coordinates of the laser total station and the computer are used to calculate the earth coordinates of the moving laser target Coordinates, because the moving laser target and the cutter head are fixedly connected, thus effectively judging the consistency between the tunneling curve of the shield machine and the design axis; in addition, through this technical solution, the laser total station is located between the moving laser target and the fixed laser target. The station instrument rotates to emit laser signals, which can ensure that the distance of the laser wire can be increased during the turning process, so as to effectively reduce the number of station moves and improve the technical effect of construction efficiency.

Description

technical field [0001] The invention relates to a shield tunnel construction system, in particular a double laser target guiding system for a shield machine. Background technique [0002] At present, tunnel shield excavation has gradually become the main means of urban underground construction by virtue of its own advantages. During the advancing process of the shield machine, especially during the turning process, the coordinates of the shield machine must be constantly monitored through the guidance system to determine the position of the shield machine. The tunneling axis, by adjusting the tunneling posture of the shield machine, ensures that the tunneling axis matches the designed theoretical axis as much as possible. The laser guidance system in the prior art includes a laser total station and a laser target. The laser total station is fixedly connected to the tunnel segment, and the laser target is fixedly connected to the middle shield of the shield machine. During th...
