[0002] The secondary lining of a tunnel is an important link in tunnel engineering construction and one of the important measures to ensure the safe operation of tunnel projects. In recent years, with the increase in the operating mileage, serious quality problems have occurred in individual tunnels, endangering the safety of train operation, interfering with the transportation order, and affecting the transportation efficiency.

[0003] During the existing construction process of tunnel secondary lining, manual vibration has a high labor intensity. Moreover, during the concrete pouring process, the concrete feeding is blocked at places where the steel bars are dense or there are reserved holes, and pouring continues upward without vibration; the vibration is insufficient or the vibration time is too long, resulting in air bubbles on the concrete surface and easy formation of cavities in the concrete, presenting a quality hazard. Therefore, the methods and measures to improve the lining quality have always been the research direction and goal in tunnel construction in recent years.

[0004] How to design a circumferential automatic vibrating system for tunnel lining trolleys that is ingeniously designed, easy to operate, reduces the labor intensity of operators, effectively shortens the concrete vibration time during the secondary lining construction of a tunnel, improves work efficiency, enhances the compactness of concrete construction, reduces air holes, improves the quality of tunnel lining concrete, and thus ensures the overall safety of the tunnel structure is an urgent problem to be solved. Summary of the Invention

[0007] As a further optimized solution for the above circumferential automatic vibration system for a tunnel lining trolley, the reel includes a turntable, a rotating shaft sleeve, and a bolt member. The turntable consists of three circular plates arranged vertically. The rotating shaft sleeve is a hollow tubular structure. The three turntables are sequentially sleeved on the rotating shaft sleeve to form a winding disc for respectively winding the external cable of the linear vibrator and the vibration power supply line. A bolt member is provided on the rotating shaft sleeve, and the transmission pipe passes through the inside of the rotating shaft sleeve. The rotating shaft sleeve is connected to the transmission pipe by the bolt member.

[0021] The reel 7 includes a turntable 701, a shaft sleeve 702, and a bolt member 703. The turntable 701 is three circular disks arranged vertically. The shaft sleeve 702 is a hollow tubular structure. The three turntables 701 are sequentially sleeved on the shaft sleeve 702 to form a winding disk for winding the external cable of the linear vibrator 10 and the vibration power cord respectively; a bolt member 703 is provided on the shaft sleeve 702, and the transmission pipe 5 passes through the inside of the shaft sleeve 702, and the shaft sleeve 702 is connected to the transmission pipe 5 through the bolt member 703.
