Problems solved by technology

Spraying a layer of white coating on the road surface has been proven to be effective in protecting the permafrost below the road surface. However, the white coating is easy to get dirty and will produce a serious "dazzling effect", resulting in the white coating roadbed not being effectively treated. use

Embodiment

[0031]Please refer tofigure 1 Embodiments of the present application provide a thermal reflective piece of gravel housing, including: Sub-base main body 2, slope 4;

[0032]The slope 4 is disposed on both sides of the street base main body 2, and the upper surface of the street base body 2 is coated with a dark near influenza reflective coating 3.

[0033]Among them, slope 4 is coated with a gray epoxy resin coating 5.

[0034]During the construction, dark near-infrared thermal reflective coating is coated on the upper surface of the street base main body 2;

[0035]A piece of gravel having a gray epoxy resin coating is laid on both sides of the street base main body 2 to form a slope 4.

[0036]Specifically, in the present embodiment, the cross section of the street base main body 2 is in a ladder, and the slope 4 is disposed on the waist of the street base main body 2, and the top surface of the slope 4 is flush with the top surface of the Sub-base main body 2.

[0037]In detail, the moisture 4 has...

Abstract

The invention provides a heat reflection type block gravel slope protection roadbed and a construction method, and relates to the technical field of infrastructure construction. According to the method, heat reflection type coatings of different colors are sprayed on a road surface and a side slope block gravel protection slope respectively so as to achieve the effect of protecting permafrost under an asphalt road surface in a permafrost region; a deep-color near-infrared heat reflection type coating is uniformly sprayed on the road surface; block gravels with gray epoxy resin coatings are laid on the two sides of the roadbed body. According to the roadbed, the reflection characteristic of the heat reflection type coating is utilized, under the condition that the road surface is kept in a dark color, absorption of the road surface and the rubble protection slope to solar radiation is reduced from the source, and the cooling capacity of rubble is further enhanced; and meanwhile, the weathering resistance of the heat reflection type coating is utilized to reduce the weathering effect of the block gravels under extremely complex conditions, so that the durable cooling of the permafrost under the asphalt pavement is realized, the stability of the subgrade (such as Qinghai-Tibet Plateau and arctic region) in the permafrost region is improved, and the smoothness of the road is ensured.

Description

Technical field[0001]In particular, the present invention relates to the technical field of infrastructure, and in particular, there is a thermal reflective block gravel housing slope and construction method.Background technique[0002]my country's multi-year frozen earth regions account for approximately 22.4% of the land area, ranking third in the world. In these multi-year frozen earth regions, there is an important infrastructure, such as Qinghai-Tibet Highway, Qinghai-Tibet and Harbin high-speed rail, etc. With the gradual implementation of my country's National Expressway Network Plan, and the development of the cold area, high-grade wide range The construction of the road is also indispensable. Taking the high-speed speed of planning and construction of the Qinghai-Tibet high speed, its dark asphalt road has significant heat absorption, polyelectric heat and heat storage characteristics, and the warming of global climate will inevitably cause great threats in the roadbed. Long-...
