切な要件となっている。2. Description of the Related Art In recent years, as the demand for advanced utilization of underground space has increased, expectations for construction of tunnels by a shield excavation method have been increasing. Is strongly required.
As is well known, in tunnel construction, including the shield method, it is technically essential to lay a tunnel along the planned alignment, and in particular, mechanical excavation In the shield method, accurate measurement of the position of the shield machine is an extremely important requirement.

角儀やジャイロコンパスを用いる方法がある。In the measurement of the position of the shield machine and the construction for construction along the tunnel planning line in such a shield method, there are conventionally known a manual survey method and an automatic survey method. ing. Of these methods, center surveying (traverse surveying) and offset surveying are the mainstream methods of manual surveying, and methods of automatic surveying that use laser ranging or a gyrocompass are alternatives to manual surveying. is there.

点がある。[0004] This latter automatic surveying method is much more rational than manual surveying. In contrast to manual surveying performed between shield excavations, surveying can be carried out constantly even during excavation, and surveying accuracy can be improved. Due to the small variation, it is gradually spreading. However, although it is an automatic surveying method that has such an excellent advantage, in the case of a method using a laser rangefinder, when the tunnel alignment is curved,
There is a disadvantage that the number of times of changing the laser distance measuring angle gauge is increased. Also, in the case of using the gyrocompass, when the shield machine moves horizontally at the same angle in the horizontal direction, the gyrocompass guides the same direction before and after moving, so it is as if in the same direction. There is a drawback in that the measurement is performed as if it were proceeding to the next step, and this appears as an error.

した距離計で測定する。More specifically, the present invention relates to a shield construction in which a tunnel is constructed by assembling segments behind a shield excavator in a horizontal and vertical direction behind a rear bogie towed by the shield excavator. A truck equipped with a self-tracking rangefinder with a drive mechanism and an inclinometer is connected by a wire etc. so that it can run and stop freely, or a self-propelled type that self-propelled and stopped by an external signal Put the traveling cart. The trolley equipped with this self-tracking rangefinder and angler irradiates a target such as a reflective prism installed at the reference point on the standing side while stopping, even when excavating with a shield excavator, and performs triangulation. With this capacity, the position of this auto-tracking rangefinder is automatically detected. Next, this automatic tracking type distance measuring goniometer, whose three-dimensional coordinate position is required at the time of shield excavation, automatically tracks a target such as a reflective prism attached to the shield excavating machine and performs a distance measuring goniometer to perform shield excavation. The position of the machine is continuously detected. Further, the bogie follows the rear bogie with the rear bogie or automatically by locking and releasing the connecting means such as a wire to the rear bogie side in a timely manner by a control signal. The distance between the rear bogie and the bogie equipped with the automatic tracking rangefinder is measured by a distance meter installed on the bogie equipped with the automatic tracking rangefinder.

When there is an obstacle and cannot be seen, the automatic tracking distance measuring goniometer can be moved horizontally or up and down to a position where the reflecting prism can be seen. Through the above series of processes, the position of the shield machine can be automatically measured from the reference point located behind the rear bogie. This surveying method increases the line-of-sight distance, and eliminates the need to change the automatic tracking distance measuring angle while measuring in real time. It is also possible to measure a new reference point position from the most appropriate point and set it at that position.
