Compared with traditional galvanized fences, the fence is 100 kilograms per ton of coal and reduced emissions of 250 kg.

Use of waste materials circulation

The small encyclopedia is called "black pollution" and belongs to the internationally recognized harmful industrial solid waste. Due to the strong heat resistance, aging resistance, and difficulty of degradation of the attributes of high -molecular elastic material attributes, it has occupied a large amount of land when landfilling and accumulating. Come seriously. How to use waste tires to turn waste into treasure? How to solve it? Let ’s take a look at ↓ 8 The Research and Application of Poly -Source Waste Glores Powder Modeling Technology Research and Application of Poly -Source Waste Plastic Pluffal Fresh Powder can realize the use of passenger cars and truck poly source tires. The two -way two -way two -way 25 kilometers of waste tire powder modified asphalt mixture is about 57,800 tons, which can effectively improve the performance of the pavement. The local standard of Henan Province has been compiled "Technical Specifications for the Construction of Dry and Waste Tire Plime Modern Asphalt Penalties", and created the Henan Provincial Provincial Provincial Work Law -Dry -mixed Direct Direct Development of Waste Tire Powder File Punish Construction Method. Comprehensive summary and refinement of the monograph on the "Application Technology of Road Plusal Powder Reform Aspiring Application Technology", it has been published by People's Transportation Press Co., Ltd. 9 Research and application of waste plastic regeneration modified asphalt technology clarify the technical requirements of waste plastic composite modifiers, adding processes and other technical requirements. Two -kilometer application. The local standard of Henan Province "Technical Specifications for the Construction of Waste Plastic Composite Reform Asphalt Pathway Construction" was compiled. 10 asphalt mixing and station waste powder waste circulation use technology research and application to form asphalt mixing and station waste powder through special curing agents to form composite gel materials, replacing cement for water stabilization gravel, waste materials can replace the sand and gravel material in cement stabilized gravel The realization of asphalt mixing and station waste powder and waste materials were achieved, and construction application technology guidelines were established. 11 Recycling of recyclable materials for the promotion and application of color separation walls to prevent noise disturbance is an important issue to solve the construction of highway projects. The recyclable materials are used for color -proof walls for the environmental sensitive sections such as residential areas and schools along the road. The sound barrier wall is used on the 18 -kilometer -sensitive section throughout the line, while the sound insulation and noise reduction effect and solid waste pollution are solved. In the field of engineering and service quality improvement

The number of cement concrete bridges in my country Encyclopedia is huge. It is mainly based on urban bridges and small -span highway bridges. With the increasingly loading transportation in recent years, the heavy type of vehicle load has been compared at the waterproof adhesion layer of the concrete bridge deck. Large shear stress leads to early ruts, pushing and supporting diseases such as the paving layer of the bridge deck. For cement concrete large -middle bridges, bridge paving is an important structure to ensure the performance of bridge. At present, my country's most uses asphalt mixture as paving materials. How to improve the life expectancy of the pavement and reduce the cost of maintenance? How to solve it? Let's take a look at the research and application of high -stick continuous waterproofing and adhesive function layers of high -stick waterproofing function layers of cement concrete bridge high -stick continuous waterproofing function layer.
