Cement concrete pavement structure of tunnel

Abstract

The invention discloses a cement concrete pavement structure of a tunnel. An assembling-type cement concrete lower surface plate, a pre-fabricated coarse skid-resistant surface layer, multiple throughholes which are installed in a whole cement concrete pavement layer, and a hollow box below the through holes are used for forming the structure for a pre-fabricated cement concrete pavement. The pre-fabricated structure is installed at a vehicle canalization wheelmark position. A cement concrete surface plate is provided with the through holes, so that a friction sound between tires and the ground can be effectively reduced. A box structure and a sound absorption material on the inner wall can be used for effectively reducing a noise in the tunnel. The pavement through holes and the box structure, and a horizontal drainage pipe at the bottom of the hollow box can be used for improving the drainage efficiency of the pavement. The cement concrete pavement structure of the tunnel is simplein structure, belongs to the pre-fabricated assembling structure, and is detachable, small in building area, convenient to construct, short in construction period, and suitable for newly constructingand reconstructing the pavement. The assembling-type pavement structure is connected by a bulge and a groove, and a gap at a joint place can be filled with a joint sealing material, such as bitumen, the installation and disassembly is convenient.

Description

technical field [0001] The invention belongs to a special pavement structure for drainage and noise reduction, in particular to a tunnel cement concrete pavement structure. Background technique [0002] In recent years, with the development of road traffic and urban construction, a large number of mountain tunnels and urban underground passages have emerged, followed by various traffic problems. On tunnel roads, the side walls of existing tunnels are mostly lined with cement walls. , is a rigid acoustic material, which is easy to form sound reflection, and the problem of traffic noise nuisance is becoming more and more serious. In addition, the noise in the tunnel is also easy to increase the psychological pressure and irritability of passers-by. At present, there are mainly OGFC pavement structures, which can drain water, reduce noise and improve the anti-skid performance of the pavement. However, due to the impact of the structure, there are defects in noise reduction and ...

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.
