Method for curing and improving furnace slag bottom ash roadbed through EICP (Ethylene-Inductively Coupled Plasma)
The invention discloses a method for curing and improving a furnace slag bottom ash roadbed through EICP (Ethylene-Inductively Coupled Plasma), which comprises the following steps: reinforcing furnace slag bottom ash by using a soybean urease induced calcium carbonate deposition technology, and generating calcium carbonate crystals around furnace slag bottom ash particles to fill pores, so that the furnace slag bottom ash particles are mutually cemented; and a layer of compact calcium carbonate hard shell is generated on the surface of the whole furnace slag bottom ash to improve the mechanical property of the furnace slag bottom ash, and the reduction of the porosity of the furnace slag bottom ash also prevents the leaching of internal heavy metals. The method has the advantages of being clean, environmentally friendly, low in energy consumption, small in soil disturbance, uniform in reinforcing effect and the like, and has reference significance in application and popularization of the slag bottom ash roadbed.
本发明公开了一种通过EICP固化改良炉渣底灰路基的方法，本发明选用大豆脲酶诱导碳酸钙沉积技术来加固炉渣底灰，在炉渣底灰颗粒周围生成碳酸钙晶体填充孔隙，使炉渣底灰颗粒相互胶结，并在整个炉渣底灰表面生成一层致密的碳酸钙硬壳以提高炉渣底灰的力学特性，炉渣底灰孔隙率的减小也阻止了内部重金属的浸出。该方法具有清洁环保、低耗能、对土体扰动小、加固效果均匀等优点，对炉渣底灰路基的推广应用具有参考意义。
