Abstract: During the construction of tunnel lining by conventional lining trolley, many problems exist, i.e. hollows, cracks and falling blocks of secondary lining, easy damage of joint part, lowefficiency of pouring condition and insufficient vibration of crown. A new intelligent lining trolley construction automatic control system integrating functions of trolley pouring condition, trolley concrete distribution system, trolley vibration system, top pressure monitoring, joint monitoring system, trolley hydraulic system, lateral pressure monitoring, walking control system and lining data reports is developed based on functional design scheme of new intelligent lining trolley, traditional construction technology, and informational and intelligent design concepts. The system was applied to Bid No.1 of Jishou Tunnel on ZhangjiajieJishouHuaihua Railway. The applicable results show that by adopting the new intelligent lining trolley construction automatic control system, the automatic, informatized and intelligent lining construction can be realized, the automation level of lining construction can be greatly improved, the labor intensity of workers can be reduced, the hollow quantities behind lining can be effectively reduced, and the lining construction quality can be improved.
