Embodiment Construction
[0014] The present invention will be further described in conjunction with the accompanying drawings. Firstly, according to the design requirements of the tunnel pipe gallery, the inner corner formwork of the pipe gallery is designed and manufactured. (4) Combine with the flat formwork (1), and use screws to screw the flat formwork from the combination inner corner formwork (4), and then combine with the wall formwork (5), and the pin (3) is inserted into the through hole by the pin piece (2) Insert the flat hole on the head of the pin (3) and lock it, and the surrounding wall formwork (5) and the combined inner corner formwork (4) are combined. After the four flat formworks are combined, the inner corner formwork of the pipe gallery is formed. To be installed in the tunnel, a section of the pipe corridor channel is formed, and the cement is poured until the cement solidifies. Remove the surrounding pins (2), take out the pins (3), take away the wall formwork (5), unscrew the ...

The invention discloses a tunnel pipe gallery inner rotating corner template. The tunnel pipe gallery inner rotating corner template comprises a wall template, a dowel, a pin plate and a flat template, and is characterized in that the combination inner corner template comprises a lower parallel surface and a left vertical surface; the upper portion slants to the lower left and then extends to theupper left along the slanting plane at a right angle until the thickness of the template is reached; the upper combination inner corner template is formed by inverting the lower right combination inner corner template and combining the lower right combination inner corner template with the upper plane wall template; a hole is formed in the middle of the lower parallel surface and is combined withthe wall template; the flat template is connected between the upper and lower combination inner corner template; and the flat template is connected with the combination inner corner templates into oneby screws. Through the four corner connecting structure, the tunnel pipe gallery inner rotating corner template has the advantages that the underground tunnel pipe gallery inner rotating corner templates are positioned in a tunnel to form a pipe gallery by cement pouring section by section, and therefore pipelines, cables and upper and lower heating pipelines can be laid; and road digging is notrequired for installation and maintenance, and vehicles can pass without hindrance.
Description
Technical field: [0001] The invention belongs to an inner corner template used in an underground tunnel pipe gallery in the field of civil engineering. Background technique: [0002] At present, domestic underground pipelines, communication cables, upper and lower heating pipelines, etc. are all dug and laid separately, which is very inconvenient, especially for maintenance, and roads have to be dug, which affects traffic. Invention content: [0003] The present invention provides an inner corner formwork of a tunnel pipe gallery, which overcomes the inconvenience of installation and maintenance of underground pipelines, communication cables, upper and lower heating pipes, etc., and affects traffic, and solves the inner corner formwork in the construction of an underground tunnel pipe gallery. Problems make it a standardized tunnel pipe gallery, so that various pipes, communication cables, etc. are laid uniformly, neatly installed, easy to maintain, there is lighting and v...
