Embodiment Construction

[0019] see Figure 1 to Figure 2 , the snow-melting and ice-melting system of highway bridge pavement based on energy piles includes heating pipeline 8, heat exchange pipe 2 and ground source heat pump equipment 5, which can be implemented according to the following steps:

[0020] 1. Install the heat exchange tube 2 in the prefabricated reinforcement cage of the bridge pile foundation 10 under the ground surface 1, then lower the reinforcement cage and pour concrete;

[0021] 2. Connect the inlet and outlet of the heat exchange tubes 2 in each pile foundation 10 with the first water outlet main pipe 3 and the first water inlet main pipe 4 in parallel and in the same way, and connect with the heat extraction end of the ground source heat pump equipment 5 to form a heat extraction In the loop, the hot end of the ground source heat pump equipment 5 is provided with a transfer switch 9;

[0022] 3. After the installation of the prefabricated beam 15 is completed, a concrete leve...

Abstract

The invention discloses a highway bridge pavement deicing and snow melting system based on energy pile and a running mode. The system comprises a heating pipeline, a heat extraction pipeline and an earth source heat pump device, wherein an earth source heat pump heat exchanger is connected with the heating pipeline and a heat extraction port of the earth source heat pump device respectively so as to form a heat storage loop and a heat extraction loop respectively; and the heating pipeline is connected with the heating port of the earth source heat pump device so as to form a heating loop. The system can thoroughly solve the problem of snow and ice on a highway bridge pavement, and can save more than 70% of energy compared with the traditional electric heating deicing and snow melting technology. Solar energy in summer is stored in underground soil for heating in winter, so that the ground temperature of rock and soil body around a pile foundation caused by unbalance of cooling and heating load is prevented from decreasing year by year.

Description

technical field [0001] The invention relates to a system for melting snow and ice, in particular to an energy pile-based system for melting snow and ice on road surfaces of highways and bridges. Background technique [0002] In my country, the weather is cold in winter, and the road and bridge decks are easy to freeze. The icing period in the south is nearly one month, and the time in the north is longer. Traffic accidents caused by snow on roads and bridges account for about 35% of the total number of traffic accidents in winter. Traffic accidents and expressway closures caused by snow and ice on bridges have brought huge social impact and economic losses. At present, there are mainly two types of methods for removing ice and snow from the bridge deck, mechanical removal method and melting method. The mechanical method is suitable for large-scale mechanized clearing operations, but it often needs to be carried out after snowfall, which hinders traffic; when the road surface...
