Problems solved by technology

[0003] At present, the general method at home and abroad to deal with the steel mold trolley passing through the conventional section of the tunnel is to reduce the overall volume of the steel mold trolley, then pass through the conventional section, and then restore it to the normal working state; this method is to disassemble the steel mold trolley The outer formwork of the mold trolley and the reduction of the span of the gantry mainly have the disadvantages of heavy disassembly and assembly workload, inconvenient construction, low efficiency, high labor intensity, and high safety risks of disassembly and assembly.

Embodiment 1

[0043] In the prior art, the method of passing the conventional section of the steel mold trolley is to disassemble and assemble the template and reduce the span of the gantry, so as to reduce the volume of the entire steel mold trolley and make it match the conventional section. This method has the advantages of low efficiency, high labor intensity and safety. Defects such as high risk. In order to overcome the defects of the prior art, this embodiment provides a steel mold trolley whose main structure can pass through a conventional section as a whole, such as Figures 1 to 4 As shown, the difference between this design and the prior art is that the main structure of the steel mold trolley is basically unchanged, such as dismantling, and the main structure of the steel mold trolley is used as a whole to pass through a conventional section. Specifically, the steel formwork trolley mainly includes a main structure and a working traveling device 4; wherein, the main structure s...

Embodiment 2

[0071] The difference between this embodiment and Embodiment 1 is that when the conventional section that the steel mold trolley needs to pass through is relatively large, the enlarged section is basically equivalent to the conventional section. Therefore, only part of the steel mold trolley needs to be adjusted. The specific method is: the height difference between the main structure of the trolley and the ground can be adjusted through the height adjustment column, and then supplemented by the removal of part of the formwork, such as the bottom mold and / or side mold, the steel mold trolley can be realized. Through the purpose of regular section, the construction efficiency is greatly improved.

Abstract

The invention discloses a steel form jumbo with main structure capable of passing conventional sections, and an implementation method thereof and mainly solves the problems such as low production efficiency, high labor intensity and high safety risk caused by the fact that the existing steel form jumbo needs removal of a form mechanism and narrowing of gantry span before passing a conventional section. The steel form jumbo comprises a jumbo main structure and an operating travelling device. The jumbo main structure is composed of a gantry, a sill disposed on the lower portion of the gantry, and a form mechanism disposed outside the gantry. The operating travelling device is mounted below the sill through height adjusting posts which are demountable height adjustment posts. The gantry is further provided with a rotating transport mechanism, and the rotating transport mechanism connected with the gantry is used for lifting, rotating and transporting the jumbo. The steel form jumbo can pass the conventional section just by removing the height adjustment posts, the operating travelling device and a lower bottom form, reserving the main structure and using the main structure as a body. The application of the steel form jumbo ensures safety, convenience and high construction efficiency. Therefore, the steel form jumbo is suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of traffic tunnel engineering construction, and in particular relates to a steel mold trolley whose main structure as a whole can pass through a conventional (small) section and a realization method thereof. Background technique [0002] Steel formwork trolley is a kind of special construction equipment used for tunnel concrete lining with steel formwork mounted on mobile trolley. Although there are various types of steel formwork trolleys, their structures are basically the same, and they are all composed of formwork parts, gantry body parts, and working walking parts. For the steel formwork trolley, the width of the steel formwork trolley is the same as that of the enlarged section tunnel in the working state. After a section of the enlarged section tunnel project is completed, the steel formwork trolley needs to go through the conventional section smaller than the enlarged section to the next enlarged se...
