Problems solved by technology
[0002] With the progress of society, the country's bridge industry is also developing rapidly. There are also various types of bridges on the market. There are many normal maintenance tasks for bridges. Due to the consideration of the service life of the bridge, the heat insulation and heat dissipation of the bridge during use is very important. It is particularly important. At present, the heat dissipation method of bridges is generally to pour water on it. The heat dissipation work is relatively heavy, and the effect of heat dissipation and heat insulation is not good.

The invention relates to the technical field of bridges, in particular to a bridge thermal insulation roadbed. The bridge thermal insulation roadbed comprises a bridge support, a bridge roadbed and abituminous pavement. A water absorption layer is arranged between the bridge roadbed and the bituminous pavement. Floor drains are evenly arranged on the bituminous pavement and connected with the water absorption layer. Water collection grooves are evenly formed in the bridge roadbed. The bridge roadbed is provided with drainage hole channels communicating with the water collection grooves and the upper end of the bridge roadbed. The other ends of the drainage hole channels obliquely penetrate through the two sides of the bridge roadbed. The water collection grooves are formed in the bridge roadbed, rainwater is stored in the water collection grooves through the floor drains, thermal dissipation and insulation work of a bridge is conducted through the thermal evaporation principle, certain moisture can be stored through arrangement of an asbestos net layer and used for conducting thermal evaporation, the service life of the bridge is greatly prolonged, and maintenance work of the bridge is reduced.

technical field [0001] The invention relates to the technical field of bridges, in particular to a bridge thermal insulation subgrade. Background technique [0002] With the progress of society, the country's bridge industry is also developing rapidly. There are also various types of bridges on the market. There are many normal maintenance tasks for bridges. Due to the consideration of the service life of the bridge, the heat insulation and heat dissipation of the bridge during use is very important. It is particularly important. The heat dissipation method of the bridge is generally to water it at present, and the heat dissipation work is relatively heavy, and the effect of heat dissipation and heat insulation is not good. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a bridge thermal insulation subgrade. [0004] In order to achieve the above object, the present invention adopts the fol...
