A tunnel cement concrete pavement structure and laying method

Abstract

The invention discloses a tunnel cement concrete pavement structure and a laying method. A prefabricated box structure is formed by using a reinforced concrete cover plate, a reinforced concrete U-shaped groove, a central connecting plate and a drainage pipe below the central connecting plate. A prefabricated box structure is set at the position of the wheel tracks, and there are through holes on the reinforced concrete cover plate of the road surface, which can effectively reduce the friction sound between the tires and the ground. The sound-absorbing material of the box structure and the inner wall can effectively reduce the noise in the tunnel. The drainage efficiency of the pavement can be improved by using the pavement penetrating hole and the box structure. The present invention has a simple structure, belongs to a prefabricated assembled structure, can be disassembled and assembled, has a small building area, is convenient for construction, and has a short construction period. When the pavement reinforced concrete cover is damaged or the surface anti-slip is missing, it is convenient and quick to remove and replace to restore traffic.

Description

technical field [0001] The invention belongs to a reinforced concrete composite box structure, and in particular relates to a tunnel cement concrete pavement structure and a laying method. Background technique [0002] In recent years, with the development of road traffic and urban construction, mountain tunnels and urban underground passages have emerged in large numbers. The side walls of the existing tunnels are mostly lined with cement walls, which are rigid acoustic materials, which can easily form sound reflections. The problem of traffic noise disturbing the residents is becoming more and more serious. In addition, the noise in the tunnels also easily increases the psychological pressure of passers-by and irritability. At present, there are mainly OGFC pavement structures, which can drain and reduce noise and improve the anti-skid performance of the pavement; there are also sound-absorbing material structures installed on the side walls of the tunnel to improve the t...

Problems solved by technology

Moreover, water is easy to accumulate in the tunnel, and the cement pavement of the tunnel is anti-skid attenuation. How to quickly remove the water in the tunnel and improve the anti-skid performance of the pavement is also a serious problem.
