DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0015] The vertical shaft air supply channel transverse partition plate and main hole secondary lining construction device refers to a device for supporting and fixing the air supply channel transverse partition plate and the main hole secondary lining. In order to ensure the stability and safety of the vertical shaft air supply channel transverse partition plate and the main hole secondary lining during construction, the secondary lining usually needs to be supported, that is, a certain support structure is arranged around the air supply channel transverse partition plate and the main hole to fix and reinforce the air supply channel transverse partition plate and the main hole.

[0016] Based on the technical defects of complex construction process and long construction period of the prior art, please refer to Figures 1-2The utility model provides a device for constructing a secondary lining of a shaft air duct diaphragm and a main hole. Compared with the existing technology, the entire construction device has the advantages of convenient construction, fast construction speed, and saved construction costs. The device includes two sets of walking rails 1 installed on the ground. The two sets of walking rails 1 are hydraulically connected to a secondary lining trolley 2. Multiple sets of hydraulic jacks 3 are installed on both sides of the secondary lining trolley 2. The telescopic shaft of the hydraulic jack 3 is fixed with a side template 4. Multiple transverse distribution beams 5 are installed on the top of the secondary lining trolley 2. Multiple wooden beams 6 are installed on the transverse distribution beams 5. A bottom formwork 7 is installed, an air duct partition 8 is cast on the bottom formwork 7, a socket and disc type bracket 9 is set on the air duct partition 8, and a plurality of arc-shaped top formworks 10 are installed on the top of the socket and disc type bracket 9; the secondary lining trolley 2 is modified, the arc-shaped formwork on the top of the trolley is removed and the secondary lining trolley 2 part is retained, and the transverse distribution beam 5, wooden beam 6 and bottom formwork 7 are set up in sequence on the secondary lining trolley 2, and then the air duct partition 8 is cast and formed on the bottom formwork 7, and finally the socket and disc type bracket 9 is set on the air duct partition 8, and the top formwork 10 of the remaining arc section of the main hole arch is installed.
