Double-hinge reversible tunnel lining trolley steel end formwork and tunnel lining trolley

Abstract

The invention provides a double-hinge reversible tunnel lining trolley steel end formwork and a tunnel lining trolley. The formwork comprises an end formwork body, which is of a sector structure having an inner cambered surface and an outer cambered surface; a stress-bearing mechanism, comprising auxiliary stress-bearing steel channels extending along the camber direction of the end formwork body and stress-bearing steel channels extending along the width direction of the end formwork body, wherein the auxiliary stress-bearing steel channels are disposed between the end formwork body and the stress-bearing steel channels, and an end of each stress-bearing steel channel close to the inner cambered surface is connected with a first connecting plate and the other end close to the outer cambered surface is fitted with a telescopic fixing rod; a telescoping mechanism, comprising auxiliary stress-bearing steel angles extending along the length direction of the end formwork body, wherein the auxiliary stress-bearing steel angles are connected with the auxiliary stress-bearing steel channels and are movably connected with the end formwork body through adjusting components. During usage, a displacement of the end formwork body along the width direction is adjusted through the adjusting components. The above-mentioned forged steel formwork is used to solve the technical problem that a tunnel construction process experiences severe delay and construction cost is greatly increased due to poor service performance of a trolley end formwork in the prior art.

Description

technical field [0001] The invention relates to the technical field of tunnel arch wall lining end formwork construction, in particular to a double hinged reversible steel end formwork of a tunnel lining trolley and a tunnel lining trolley. Background technique [0002] The development of modern science and technology has accelerated the pace of modernization construction. Infrastructure projects such as urban rail transit are a type of modernization construction. The progress of science and technology has promoted the increasing number of projects. For the tunnel construction, the roadheader is the core of the tunnel construction process. equipment, its application in my country shows a linear upward trend; at the same time, the geographical application scope of the synchronous lining construction technology of cast-in-place concrete side and roof arches matched with roadheaders is also expanding. In the process of secondary lining construction of existing tunnels, large hydr...
