Embodiment Construction

[0023] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0024] A tunnel lining trolley with a push-pull end form, including a lining trolley, a number of adjacent guide steel frames 1 are sequentially welded in the peripheral direction of the rear end of the lining trolley, and each guide steel frame 1 is provided with a Relatively its sliding also can block steel formwork 6 relative to its fixed end.

[0025] The upper side of the end-blocking steel formwork 6 is provided with a wave-shaped tooth structure 8, and the upper frame surface of the guide steel frame 1 is pierced with a compression bolt 3 perpendicular to the end-blocking steel formwork 6, and the guide steel frame 1 A reverse check device is installed at the bottom of the upper frame. The reverse backstop device includes a backstop steel plate 10 hinged on the bottom of the upper frame surface of the guide steel frame 1, the lower end of t...

Abstract

The invention belongs to the technical field of lining trolleys for tunnel engineering construction processes, and particularly relates to a tunnel lining trolley with a push-pull end die and a secondary tunnel lining pouring method implemented by the same. The problems that the quality is difficultly ensured and the construction time is difficultly ensured in the conventional secondary tunnel lining construction are solved. A plurality of adjacent guide steel frames are sequentially welded in the circumferential direction of the periphery of the rear end of the lining trolley, and an end blocking steel template capable of sliding and being fixed relative to each guide steel frame is arranged in each guide steel frame. The secondary tunnel lining pouring method comprises the following steps of: continuously pushing the end blocking steel templates after the lining trolley is in place, screwing down compression bolts, clamping a reverse check device, and casting concrete to form a secondary tunnel lining. The invention has the advantages of effectively solving the problem of additionally erecting a die by manpower, ensuring the construction quality of the secondary lining, saving the die erecting time of the secondary lining, greatly improving the effect of the secondary lining construction and achieving remarkable effect of shortening the construction period of the whole tunnel building engineering.

Description

technical field [0001] The invention belongs to the technical field of a lining trolley in the tunnel engineering construction process, and in particular relates to a tunnel lining trolley with a push-pull end form and a completed tunnel secondary lining pouring method. Background technique [0002] With the development of the economy and the increase of the population, the shortage of transportation resources has become a restrictive factor. At present and for a long time in the future, my country and even the world must concentrate on the construction of transportation, among which tunnels are currently one of the most important ways to solve the problem of transportation. First, the construction of tunnels is inseparable from the construction of urban transportation, current passenger dedicated lines and high-speed railways. At present, the tunnel construction process is mainly divided into the following four process steps: (1) Excavation, (2) Initial temporary support, (3...
