Embodiment Construction

[0043] The following is attached Figure 1-4 The application is described in further detail.

[0044] The embodiment of the present application discloses a hydraulic jacking integral steel end formwork for the second lining of a highway tunnel. refer to figure 1, the hydraulic jacking integral steel end formwork for the secondary lining of the highway tunnel is placed on the ground and is used to block the end face of the secondary lining, including a pedestal 1, a hydraulic component 2 and an end formwork 3, the hydraulic component 2 is connected to the pedestal 1, and the end There are several templates 3, and the several end templates 3 are all connected to the hydraulic assembly 2, and the hydraulic assembly 2 is used to expand or fold the several end templates 3. When in use, the pedestal 1 is transported to the set position, and then several end formworks 3 are unfolded through the hydraulic assembly 2. After the secondary lining is completed, the several end formworks...

Abstract

The invention relates to the field of road tunnel construction, in particular to a road tunnel secondary lining hydraulic jacking integral type steel end mold which is used for blocking a secondary lining end face and comprises a pedestal, a hydraulic assembly and a plurality of fan-ring-shaped end mold plates, a hinge piece is arranged between every two adjacent end mold plates, and the hydraulic assembly is arranged between the pedestal and the hydraulic assembly. The hinging pieces are used for hinging every two adjacent end formworks, the end formworks are matched with the end face of the secondary lining, the sides, close to each other, of every two adjacent end formworks abut against each other, the hydraulic assembly comprises a plurality of first hydraulic cylinders and a hydraulic pump station, the first hydraulic cylinders are connected with the hydraulic pump station, the fixed ends of the first hydraulic cylinders are hinged to the pedestal, and the fixed ends of the first hydraulic cylinders are connected with the hydraulic pump station. The movable ends of the first hydraulic cylinders are connected with the hinge pieces, and one hinge piece is arranged between every two adjacent first hydraulic cylinders. The invention further relates to a construction method of the steel end mold. The secondary lining end formwork has the effect that the secondary lining end formwork is convenient to mount and dismount.

Description

technical field [0001] The present application relates to the field of road tunnel construction, in particular to a hydraulic jacking integral steel end formwork for the secondary lining of a road tunnel and a construction method. Background technique [0002] During the construction of highway tunnels, the excavated tunnel is usually initially supported first, and then the secondary lining is carried out by the lining trolley, and the tunnel is reinforced by the secondary lining. [0003] At present, in the process of secondary lining, wooden formwork is mainly used as the end formwork for lining and pouring concrete. The wooden end formwork is generally made on site, and then the finished wooden end formwork is spliced, and the wooden end formwork after splicing is completed Blocking end formwork as secondary lining. [0004] Since the wooden end formwork blocks the secondary lining by splicing, the end formwork is not easy to install and disassemble, thereby reducing the...
