Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, inside the tunnel 1,
A concrete pavement 2 is provided, and members 4 constituting a circular waterway 3 are provided on both sides thereof.

In this case, the member 4 constituting the circular channel 3 is hit first, and then the concrete of the concrete pavement 2 is hit. The construction of such concrete is carried out by a slip-form method in which a concrete structure is continuously constructed while compacting and molding concrete into a predetermined shape using a self-propelled construction device equipped with a compacting device and a molding device. 5 indicates the position of the caterpillar of the self-propelled construction machine, which is installed at a lateral margin 6 lateral to the plate edge.

A self-propelled construction machine is provided with a guide sensor for detecting a reference plane in a construction direction and a grade sensor for detecting a reference plane for construction height, based on detection signals from both sensors. And a control device for controlling the construction direction and construction height of the self-propelled construction machine.

The method for controlling the construction direction and construction height of a self-propelled construction machine according to the present invention has the following features. That is, in view of the difficulty in securing a lateral margin for setting a reference plane in the construction direction by the guide sensor and a reference plane in the construction height by the grade sensor, the construction width in the tunnel 1 is difficult. The present invention is characterized in that predetermined portions of the member 4A constituting the circular water channel 3 installed on both sides of the above are used as a reference plane in the construction direction and a reference plane for the construction height.

A control device that specifically executes the above method is configured as follows. That is, in FIG. 2, the guide sensor 7 is configured such that its sensor portion 7A detects the inner surface of the groove 3A communicating with the water channel 3 formed on the upper surface of the member 4 constituting the circular water channel 3 as a reference surface in the construction direction. , Groove 3A
And is vertically inserted into the water channel 3 to be in contact with the inner surface of one groove.

In FIG. 3, the grade sensor 8 is
The sensor portion 8A is vertically arranged so that the upper surface of the member 4 constituting the circular waterway 3 is detected as a reference surface of the construction height, and the tip thereof contacts the upper surface of the member 4 forming the circular waterway 3. Is done.

As shown in FIG. 4, a ski-shaped guide member 9 is rotatably connected to the tip of the sensor portion 8A of the grade sensor 8, so that the sensor portion 8A forms a circular waterway 3. It is preferable to make it so that it moves smoothly along the upper surface of 4.

According to the control method and the control device, the predetermined locations of the members 4 constituting the circular water channel 3 installed on both sides of the construction width in the tunnel 1 are used as the reference plane in the construction direction and the reference plane for the construction height. Since the construction direction and the construction height of the self-propelled construction device are controlled, the side margin for setting the construction direction reference plane and the construction height reference plane in the tunnel 1 is set. Even if it is difficult to secure the width,
It is easy to set a reference plane in the construction direction by the guide sensor 7 and a reference plane in the construction height by the grade sensor 8, and stable control is possible.

In particular, when the road has two lanes or three lanes, a larger self-propelled construction machine is used. Therefore, the reference surface in the construction direction by the guide sensor 7 and the construction height by the grade sensor 8 are used. This is extremely effective when it is particularly difficult to secure a lateral margin for setting the reference plane and the reference plane.

Further, unlike the related art, there is no need to adopt a method of attaching a support base to the inner wall of the tunnel and attaching a sensor rope to the same, so that the inner wall of the tunnel is not damaged and, in particular, no manpower and time are required.
