the body of the telescopic driving device 900 is fixedly connected with one of the stepping supporting seats 700, and the telescopic end of the telescopic driving device 900 extends along the direction of the other stepping supporting seat 700 and is fixedly connected with the side die assembly 200.

When the trolley is in the supporting state, as shown in fig. 1, at this time, the top die assembly 100 and the side die assembly 200 respectively abut against the top wall and the side wall of the tunnel 000, and both ends of the brace 500 are respectively and fixedly connected to the first brace fixing point 310 and the second brace fixing point 320. The brace bar 500 can support and position the top die assembly 100 and the side die assembly 200.

As shown in fig. 2, when the mold is to be removed, the brace 500 is removed, and the horizontal traveling devices 610 at the bottom of the two sideform assemblies 200 move in opposite directions to drive the sideform assemblies 200 to rotate around the hinge 400, so that the two sideform assemblies 200 are separated from the side wall of the tunnel wall 000. In the walking process of the horizontal walking device 610, the telescopic supporting device 620 extends to adapt to the demolding process, the horizontal walking device 620 keeps in contact with the ground, after the side formwork assembly 200 is inclined, the total height of the support becomes lower, the top formwork assembly 100 erected on the two side formwork assemblies 200 descends, the top formwork assembly 100 is demolded with the top of the tunnel wall 000, and then the demolding work of the whole tunnel is completed, the demolding efficiency is high, the construction period is shortened, and the construction cost is reduced.

At this time, as shown in fig. 3, the traveling system of the mobile cart is supported by the extension support devices 620 provided on both sides of the sideform assembly 200 in an extended state, and the horizontal traveling device 610 receives the weight of the entire apparatus.

When the cart is moved, the retractable support unit 620 is first lowered, and as the retractable support unit 620 is continuously lowered, the horizontal traveling unit 610 at the bottom of the retractable support unit 620 is finally separated from the supporting relationship with the ground, and is supported by the stepping support base 700 in contact with the ground, and the state shown in fig. 4 is entered. At this time, the two stepping support bases 700 are in a supporting state with the ground, and the walking device 610 is not stressed.

The weight of the entire sideform assembly 200 is borne by the stepping support base 700. The stepping support base 700 is fixed relative to the ground. Some auxiliary means may be provided to fix the stepping support base 700.

Subsequently, the extension driving unit 900 starts to extend, because the stepping support 700 is fixed relative to the ground, and the extension driving unit 900 drives the side form assembly 200 to slide on the two stepping supports 700 along the extension direction of the extension driving unit 900 along with the extension of the extension driving unit 900.

When the telescopic driving device 900 reaches the limit extension length, the telescopic supporting device 620 starts to lift, the horizontal walking device 610 contacts with the ground for supporting, and the state of fig. 3 is entered again. At this time, the stepping support 700 is separated from the ground, and the horizontal traveling device 610 is fixed relative to the ground. Then the telescopic driving device 900 starts to contract because the extending end of the telescopic driving device 900 is fixedly connected with the side form assembly 200, and the base of the telescopic driving device 900 is fixedly connected with the horizontal running device 610. In the process of shrinking, the retractable driving device 900 pulls the two stepping supporting bases 700 to slide forward under the side die assembly 200 until the retractable driving device 7 and 500 reaches the shrinking limit, thereby completing a stepping action.

Because the distance of advance per stepping action is limited. The above-mentioned stepping operation needs to be repeated for many times until the whole trolley is sent to the next station.

After the trolley enters the next station, the telescopic supporting device 620 starts to extend, the horizontal walking devices 610 provide support, then the two horizontal walking devices 610 move backwards until the side form assembly 200 is driven to contact with the top of the inner wall of the tunnel 000, the supporting state in the figure 1 is achieved again, and then the upper supporting rods 500 are connected and installed. And then concrete pouring and the like are performed.
