Push sliding type disk lock support heavy lining trolley and method for constructing lining form

Abstract

The invention discloses a push sliding type disk lock support heavy lining trolley. The trolley comprises a lining form system, a disk lock type full framing, a trolley chassis and stand columns, wherein a screw jack is installed at the top end of each stand column, and all the screw jacks can jointly jack or lower the lining form system through a longitudinal through beam, a plurality of horizontal pushing oil cylinders are arranged on the rear portion of the trolley chassis in a left-right spaced mode, the rear end of each horizontal pushing oil cylinder abuts against a transversely-extendedoil cylinder support, and at least two pieces of threaded steel are adopted at the rear portion of each oil cylinder support to be inserted into tunnel bottom plate concrete as counter force supports. Meanwhile, the invention also discloses a method for constructing a lining form by utilizing the above-mentioned push sliding type disk lock support heavy lining trolley. The lining trolley specially used for ultra-large-span tunnel lining construction can be recycled and reused, so that the time-consuming and cost-consuming caused by the fact that the trolley is built again after being dismantled are avoided, and the trolley is safe, reliable and 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
