Detailed Description

An assembled temporary road comprises a steel plate surface layer 1, a honeycomb noise reduction layer 2, a gravel cushion layer 3 and a soil layer 4 which are sequentially arranged from top to bottom as shown in figure 1.

The soil layer 4 is positioned at the bottommost part and is used as a foundation of the whole temporary road; the soil layer 4 is here tamped.

The gravel cushion layer 3 is located on the soil layer 4, waste stones can be directly used on the construction site and serve as secondary support, and the thickness of the gravel cushion layer 3 is 100-300 mm. In the embodiment, the broken stone cushion layer 3 consists of stones, wherein the particle size of the stones is 5-30 mm; the stones with the particle size range are convenient to implement, the road stability is higher, and meanwhile, the effects of noise reduction and drainage can be achieved to a certain extent.

The honeycomb noise reduction layer 2 is used for reducing noise and simultaneously realizing drainage. Wherein, the honeycomb noise reduction layer 2 comprises precast blocks, and the construction period can be shortened by selecting the precast blocks, so that the traffic is opened rapidly. The precast block is also made of steel. An anti-rust layer is arranged on the outer surface of the precast block, so that the service time of the temporary road is prolonged. Evenly distributed has the hole 9 of making an uproar that falls that runs through the setting along prefabricated section thickness direction on the prefabricated section, and the cross section of the hole 9 of making an uproar that falls is personally submitted the hexagon, and the aperture of the hole 9 of making an uproar that falls is 80~100mm, and heavy road surface aperture can set up a little more, and medium-sized road surface is inferior, and light road surface aperture can set up a little to satisfy the intensity requirement. The noise reduction holes 9 can effectively reduce the noise of the automobile and achieve the aim of civilized construction.

And a drainage channel 10 is connected between the adjacent noise reduction holes 9, the drainage channel 10 is arranged in parallel to the precast block, and in addition, the drainage channel 10 is arranged inside the precast block. Size of cross section of the drain passage 10: the width and the height are both 30-50 mm. The size of the drainage channel 10 is limited because the too narrow noise reduction holes 9 are likely to cause clogging of sand and mud during drainage, which affects the drainage effect.
