Problems solved by technology
[0004] However, most of the current aluminum foam materials are used as electromagnetic shielding materials for electronic equipment, or as sound insulation materials for road engineering, or as heat exchange materials for aerospace applications, and have not been used for tunnel fire prevention. Therefore, there is a lack of further research on related construction methods in the industry

The invention discloses a tunnel foamed aluminum plate and secondary lining concrete integral pouring construction method, and relates to using of a specially-made connecting piece. The connecting piece comprises a first component and a second component, wherein the first component is of a columnar structure, a threaded hole is formed inside the first component, external threads are arranged outside the first component, the second component is of a panel structure and is vertically connected with the end of the first component, and a first through hole and a second through hole corresponding to the threaded hole are formed in the second component. The method comprises the following steps that S1, one face of a foamed aluminum plate is attached to the face, away from the first component, of the second component, and the foamed aluminum plate is fixedly connected with the connecting piece through cooperation of a screw and the first through hole; S2, the other face of the foamed aluminum plate is attached to a trolley panel, and the trolley panel, the foamed aluminum plate and the connecting piece are fixedly connected through cooperation of bolts and the threaded hole in the first component; S3, a trolley is in place, and secondary lining construction is conducted; and S4, the bolts are dismounted, and surface treatment is conducted. The construction method improves the operation efficiency while guaranteeing the installation strength of the foamed aluminum plate.
Description
technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a construction method for integral pouring of a foam aluminum plate and secondary lining concrete for a tunnel. Background technique [0002] Once a fire breaks out in the tunnel, in addition to causing great damage to vehicles and personnel, the high temperature will also cause concrete bursting and deterioration of mechanical properties, causing varying degrees of damage to the lining structure, greatly reducing the bearing capacity and safety of the tunnel itself. Therefore, it is necessary to take certain protective measures to maintain the integrity and stability of the reinforced concrete structure in the event of a fire, so as to achieve the purpose of fire prevention of the tunnel structure. At present, the fire protection of tunnels mainly adopts simple methods such as spraying non-intumescent fireproof paint on the tunnel lining and laying fireproof boards, a...
