[0002] Invert filling is a key process in tunnel construction. The smooth construction of the filling surface can ensure vehicle passage and the progress of the excavation surface project. The filling surface is usually 4.4 meters or wider, with high flatness requirements. After the concrete is built, it needs to be vibrated and leveled immediately.

[0003] Because there is a trestle above the filling surface, the construction space is narrow, and it is impossible to build simple working platforms such as wooden boards. Therefore, vibrating and finishing have become the construction difficulties of the filling surface. When relying on manual vibration, a backpack vibrator is used. When vibrating a large area, workers still need to walk around with the vibrator on their backs, which has a high labor intensity and may also miss some areas. Content of the Utility Model

[0015] In this application, 1. When pouring the invert filling, the vibrating rod vibrates the filling concrete in a vertical state.

[0016] 2. When the filling concrete is poured to the designed height, the oil cylinder is retracted to separate the vibrating rod from the concrete.

[0017] 3. Then the screeding frame vibrates and levels within a range of 12 meters of the invert filling;

[0018] The vibrating screeding frame is hung on the longitudinal track beam on the channel formwork. The formwork is driven to travel through a pulley cycloidal hydraulic motor and can travel back and forth;

[0028] 8. After sufficient vibration, withdraw the vibrator from the concrete, and finally use the plastering mechanism to level the concrete. BRIEF DESCRIPTION OF THE DRAWINGS
