Coal gangue filler and construction method for filling railroad bed with coal gangue filler
The invention relates to coal gangue filler and a construction method for filling a railroad bed with the coal gangue filler. In order to make up the blank, the method comprises the following steps: preparing raw materials to enter a field for detection; treating the foundation; crushing and screening the coal gangue; mixing slaked lime, water glass and a flame retardant, and adding coal gangue to obtain coal gangue filler; material distribution and paving are carried out on the foundation, secondary mixing is carried out, and compaction is carried out after the uniformity is detected; the compactness and the cross slope flatness are detected, and the side slope is trimmed; the coal gangue is subjected to grading type selection by detecting the saturated uniaxial compressive strength, ignition loss, water absorption, softening coefficient and grading of the coal gangue. According to the invention, not only can the coal gangue be ensured to meet the pavement performance of the roadbed filler, but also the utilization limitation of the coal gangue in different producing areas can be broken, the problem of filler shortage in railway construction is effectively solved, meanwhile, the railway construction cost is reduced, and remarkable social benefits and economic benefits can be brought from the aspects of carbon reduction, disaster reduction, environmental protection and economy.
本发明涉及一种煤矸石填料及其填筑铁路路基的施工方法。利用煤矸石作为铁路路基填料目前未有先例，本方法为弥补该空白，提出：准备原材料进场检测；处理地基；破碎筛分煤矸石；拌合熟石灰、水玻璃和阻燃剂，加入煤矸石，获得煤矸石填料；在地基上布料、摊铺，进行二次拌和，检测均匀度后压实；检测压实度、横坡平整度，修整边坡；煤矸石通过检测其饱和单轴抗压强度、烧失量、吸水率、软化系数和级配进行分级选型。本发明不仅能保证煤矸石满足作为路基填料的路用性能，也能打破不同产地煤矸石利用的局限性，有效解决铁路建设中填料短缺的难题，同时降低铁路建设成本，从降碳、减灾、环保、绿色、经济的角度都能带来显著的社会效益和经济效益。
