Have you ever thought that the permeable bricks on the pavement of the community, the park where the aunts dance square dance every day, and the sculptures several kilometers away can all come from the demolished waste bricks and old tiles.
With the comprehensive renovation of the demolition and relocation of Zhengzhou's urban villages, Chenzhai, known as "Little Hong Kong" in the past, is also facing demolition. A large number of urban villages such as Liuzhuang, Liulin, and Shifo are already in the wave of demolition. Follow along. How to avoid the situation of "garbage siege"? In Zhengzhou High-tech Zone, a new way of recycling construction waste is being quietly carried out.
Recently, at a project site in the high-tech zone, forklifts stacked various construction wastes such as concrete bricks and muck of different sizes near the mobile crushing station for on-site disposal.
In the sound of roaring machines, the construction waste of the old house was crushed and screened layer by layer and turned into reclaimed sand and recycled aggregates of different particle sizes. Manager Zhu, the person in charge of the project, smiled, and the stone that had been on his mind for a long time finally fell, "In this way, we have found a solution to the construction waste generated by the demolition of villages in the city."
What can the separated recycled aggregate be used for?
According to Manager Zhu, this construction waste mobile crushing station can crush 500 tons of construction waste per hour. The crushed and screened aggregate can be used as backfill materials for road base construction and pipeline construction in municipal engineering, which can replace sand and gravel and reduce costs. . According to preliminary estimates, if all the construction waste generated from the renovation of urban villages in the high-tech zone is treated, more than 80 million yuan can be saved in transportation costs alone.
According to data, every 10,000 square meters of new buildings will generate 400 to 600 tons of construction waste, and every 10,000 square meters of buildings will be demolished, and about 7,000 tons of construction waste will be produced.
At present, except for a small amount of construction waste used for engineering backfill in my country every year, the rest are handled in a simple and extensive way, which has caused huge pressure on limited land resources. Construction waste has become a major problem facing the city.
Combined with the actual market situation, Bellian Machinery has launched a mobile crushing station that "eats" construction waste. What is swallowed is annoying construction waste, and what is spit out is precious building materials, but what is saved is real money. The cost of construction waste disposal and material costs.
