Problems solved by technology

The common disadvantage of this kind of lining construction equipment and the traditional formwork trolley is that during the lining construction, the lining construction equipment installed in the tunnel cannot pass the transport vehicles, so that the excavation of the tunnel cannot be carried out in parallel with the lining construction. The operation of other processes also interferes seriously, resulting in low efficiency and long construction period, which cannot meet the construction requirements of long railway tunnels

Embodiment Construction

[0009] As shown in Figures 1 and 2, the structure of this tunnel full-loop integrally molded lining formwork trolley includes a frame beam with a retractable front support 3, a rear support 11, a front anti-floating platform 5, and a rear anti-floating platform 10 9. The frame 7 installed on the frame beam 9, the upper template cylinders 14, 15 installed on the frame 7, the side template cylinder 16 and the corresponding upper template 6 connected to each cylinder, the side template 13 and the frame The guide wheel guide rail structure 8 between the beam 9 and the frame 7, the structural relationship among the above-mentioned components, the bottom mold 18, the winch 4 that makes the frame and the frame beam alternately move, the pump station 19 and other components can all follow the existing structure. Technical composition. The upper template oil cylinder can be used together with a widening telescopic oil cylinder 14 and a jacking oil cylinder 15 to facilitate the lining to me...

Abstract

A shuttering trolley for asting the whole ring lining in tunnel is composed of the telescopic front and back supporters, the front and back frame beams for anti-floating platform, main frame installed on said frame beams, various shuttering cylinders installed on said main frame, various shutterings connected to relative cylinders, and the rollers and guide tracks between said frame beams and main frame. Its advantages are high quality of lining without longitudinal seam, and high casting speed.

Description

Technical field [0001] The invention relates to a device for pouring tunnel linings. In particular, it relates to a formwork trolley for pouring tunnel linings. Background technique [0002] The traditional formwork trolley is mainly composed of a lining trolley, various formwork cylinders installed on the frame of the trolley, and each formwork connected to the formwork cylinder. The construction process is: invert or paving → low side wall → side wall and Top arch. One of its shortcomings is that the lining cast by this formwork trolley will leave multiple construction longitudinal joints between the side wall and the low side wall, the bottom and the low side wall, and this construction longitudinal joint will greatly weaken the tunnel bottom. The structural strength, under the rolling pressure of vehicles, will become a passage for underground water turning, which will cause the bottom of the tunnel to sink or drum up, mud on the track bed, and cracks in the wide concrete sle...
