[0004] The inverted arch is one of the main components of the tunnel structure. It is the foundation of the tunnel structure. On the one hand, it must pass the ground pressure on the upper part of the tunnel through the tunnel side wall structure or effectively transfer the load on the road to the ground. Resist the reaction force from the lower part of the tunnel, so the inverted arch is an important building component. In the existing inverted arch, it is still fixed on the side wall of the tunnel through brackets. Due to the need for combined installation of the inverted arch , thereby reducing the pouring efficiency of the tunnel, and there is no inverted arch trestle device for the tunnel at present

The invention provides an invert arch trestle device for a tunnel. The invert arch trestle device comprises an end part arch frame (1) which spans across the inner part of the tunnel, an inverted arch framework (3) which is connected with the end part arch frame (1) and is arranged at a side face part of the end part arch frame (1), an inverted arch template (2) which is arranged on the inverted arch framework (3) and is used for forming a pouring side wall of the tunnel, and a central ditch template (9) which is arranged on the inverted arch framework (3) and is used for forming a tunnel pouring central ditch; the inverted arch template (2) acts on a tunnel side wall through the end part arch frame (1) and the inverted arch framework (3), and the central ditch template (9) acts on the central part of the tunnel through the end part arch frame (1); concrete is poured into the inverted arch template (2) and the central ditch template (9), and tunnel formation is carried out; an invert arch is not fixed on the tunnel side wall through a bracket any more, so that the pouring efficiency of the tunnel is improved.
Description
[0001] 1. Technical field [0002] The invention relates to an inverted arch trestle device, in particular to an inverted arch trestle device used in tunnels. [0003] 2. Background technology [0004] The inverted arch is one of the main components of the tunnel structure. It is the foundation of the tunnel structure. On the one hand, it must pass the ground pressure on the upper part of the tunnel through the tunnel side wall structure or effectively transfer the load on the road to the ground. Resist the reaction force from the lower part of the tunnel, so the inverted arch is an important building component. In the existing inverted arch, it is still fixed on the side wall of the tunnel through brackets. Due to the need for combined installation of the inverted arch , thereby reducing the pouring efficiency of the tunnel, there is not yet a kind of inverted arch trestle device for the tunnel. [0005] Based on the existing technical problems, technical features and technic...
