Treatment system and method for building waste directly used as roadbed fillers

Abstract

The invention discloses a treatment system and method for building waste directly used as roadbed fillers. The treatment system comprises a vibrating feeding machine, a jaw crusher, a heavy type sieving machine, a small sieving machine which is connected with a 0-25mm discharging outlet of the heavy type sieving machine, a washing machine which is connected with a 25-50mm discharging outlet of theheavy type sieving machine, an impact crusher which is connected with a more than 50mm discharging outlet of the heavy type sieving machine, and a finished product sieving machine, wherein an discharging outlet of the finished product sieving machine is connected with an discharging outlet of the impact crusher. A discharging outlet of the washing machine is connected with a feeding inlet of theimpact crusher. The vibrating feeding machine, the jaw crusher, the heavy type sieving machine, the small sieving machine, the washing machine, the impact crusher and the finished product sieving machine all are connected with a control chamber. The treatment system and method for the building waste directly used as the roadbed fillers has reasonable structure design and high automation degree, and has the advantages of noise reduction, dust removal and cleaning of sundries, the recycled fillers after treatment can replace lime soil and gravelly soil for roadbed filling, low carbon and environmental protection are achieved, and the recycling utilization rate is high.

Description

technical field [0001] The invention relates to the field of construction waste treatment, in particular to a treatment system and a treatment method in which construction waste is directly used as roadbed filler. Background technique [0002] For a long time, lime soil and gravel soil are widely available and cheap, and are widely used as subgrade fillers. With the development of social economy, the demand for lime soil and gravel soil is increasing. At present, my country is in an unprecedented upsurge in infrastructure construction. The construction of a large number of projects requires a huge amount of lime and gravel. Long-term mining has led to serious resource depletion, ecological environment damage, soil erosion and other problems. The contradiction of shortage of raw material resources has become increasingly prominent. [0003] On the other hand, with the continuous development of the city, the demolition of the old city produces a large amount of construction w...

Problems solved by technology

At present, my country's construction waste treatment methods are generally divided into two categories: one is to bury or dump construction waste in a fixed place, which will occupy a large amount of land resources, and some heavy metals in construction waste will penetrate into the soil or groundwater, causing serious damage. environmental pollution

The second is the recycling of construction waste. However, due to the poor cleaning of light waste in the prior art, the treatment effect is poor, and it cannot meet the requirements of being directly used as roadbed filler.
