Problems solved by technology
However, the construction method of pouring on-site tunnel inverted arch structure not only requires multiple construction steps, but also has a low degree of mechanization, which makes it take a long time for the tunnel inverted arch structure to harden and form and can bear force. Deformation and settlement often cannot be controlled in a timely and effective manner

The invention relates to the technical field of tunnel structures, in particular to a tunnel inverted arch structure. A second inverted arch prefabricated part is detachably connected with two first inverted arch prefabricated parts; first mounting grooves are formed in the tops of the first inverted arch prefabricated parts, and two second mounting grooves are formed in the top of the second inverted arch prefabricated part; a first prefabricated filling component comprises a first support plate, first bearing plates and second bearing plates which are integrally formed; the first bearing plates and the second bearing plates are perpendicular to the bottom surface of the first support plate; the two second bearing plates are correspondingly and detachably inserted into the first mounting grooves, and the two first bearing plates are correspondingly and detachably inserted into the second mounting grooves; a second prefabricated filling component comprises a second support plate and two third bearing plates which are integrally formed, and the third bearing plates are perpendicular to the bottom surface of the second support plate; and the two third bearing plates are correspondingly and detachably inserted into the second mounting grooves. The invention aims to provide the tunnel inverted arch structure which can be quickly assembled so as to timely and effectively control deformation and settlement of an excavated road section.
Description
technical field [0001] The invention relates to the technical field of tunnel structures, in particular to a tunnel inverted arch structure. Background technique [0002] The traditional tunnel inverted arch structure construction is to use on-site operations, that is, artificial binding of steel bars and formwork cast-in-place concrete at the construction site. However, the construction method of pouring on-site tunnel inverted arch structure not only requires multiple construction steps, but also has a low degree of mechanization, which makes it take a long time for the tunnel inverted arch structure to harden and form and can bear force. Deformation and settlement often cannot be controlled in a timely and effective manner. Therefore, it is necessary for the tunnel construction to construct the inverted arch structure of the tunnel quickly so that the tunnel structure can be closed into a ring as soon as possible and form a stressed whole.
