Construction method of heavy-duty lining trolley and lining formwork of push-pull type buckle support

Abstract

The invention discloses a heavy-duty lining trolley of push-pull and slide-type disc buckle support, which includes a lining formwork system, a disc buckle-type full hall support, a chassis of the trolley, and a column. A screw jack is installed on the top of each column, and all the screw jacks can The lining formwork system is jointly lifted or lowered through the longitudinal beams; a number of horizontal jacking cylinders are arranged at intervals on the left and right behind the chassis of the trolley, and the rear end of each horizontal jacking cylinder is against the horizontally extending cylinder support, and the rear of the cylinder support At least two rebars are inserted into the concrete of the tunnel floor as reaction support. At the same time, the invention also discloses a lining template construction method using the above-mentioned heavy-duty lining trolley of the pushing and sliding buckle bracket. The lining trolley specially used for super-long-span tunnel lining construction can be recycled and reused to avoid time-consuming and costly re-installation after dismantling. It is safe, reliable and has a high bearing capacity.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, and in particular relates to a heavy-duty lining trolley of a push-and-slide type buckle bracket suitable for super-large-span tunnels, and a construction method of a lining formwork using the heavy-duty lining trolley. Background technique [0002] As far as we know, the span of the tunnel that needs to be lined is no more than 40 meters. The span of the general road and railway tunnel is more than ten meters. The lining trolley adopts the hydraulic trolley processed by section steel and steel plate. Big. [0003] Large-span cast-in-place concrete bridges and other similar projects are generally constructed with full-wall brackets or Bailey beam brackets. After each bracket is erected and poured, it cannot be moved. It can only be dismantled and transferred to a new location. ; Especially for tunnels with tight construction schedules, a large number of trolleys need to be inves...

Problems solved by technology

[0002] As far as we know, the span of the tunnel that needs to be lined is no more than 40 meters. The span of the general road and railway tunnel is more than ten meters. The lining trolley adopts the hydraulic trolley processed by section steel and steel plate. Big

[0003] Large-span cast-in-place concrete bridges and other similar projects are generally constructed with full-wall brackets or Bailey beam brackets. After each bracket is erected and poured, it cannot be moved. It can only be dismantled and transferred to a new location. ; Especially for tunnels with tight construction schedules, a large number of trolleys need to be invested, and the cost is very high. In addition, the assembly in the tunnel is difficult, and the risk factor of hoisting large formwork in the tunnel is high and the assembly of the trolleys takes a long time
