The invention discloses a method for improving a roadbed by using coal gangue, and relates to the technical field of roadbed improvement, and the method is technically characterized by comprising the following steps: crushing collected coal gangue through crushing equipment, cleaning, screening and removing impurities to obtain a coal gangue raw material with uniform particles, and taking 10-30 parts of the coal gangue raw material; the preparation method comprises the following steps: mixing 30-60 parts of cement, 60-120 parts of sand and 120-240 parts of gravel to obtain a concrete raw material; taking 5-15 parts of silicate to obtain a filling material; 5-45 parts of a noise reduction material is taken and smashed; taking 10-60 parts of an insect-inhibiting material for later use; the coal gangue raw material, the concrete raw material, the filling material, the insect-inhibiting material and the noise-reducing material are mixed according to a corresponding proportion, and the technical effects are that calcium silicate and coal gangue react to form silicate gel, and the gel can fill pores in the coal gangue and improve the compactness and hardness of the coal gangue, so that the strength and durability of the concrete are improved, and the service life of the concrete is prolonged. And the purpose of improving the roadbed strength is achieved.
本发明公开了一种利用煤矸石改良路基的方法，涉及路基改良技术领域，其技术要点包括以下步骤，将收集煤矸石通过粉碎设备进行粉碎，经过清洗和筛选，去除杂质，得到颗粒均匀的煤矸石原料，取10‑30份的煤矸石原料；取混30‑60份的水泥，60‑120份砂子、120‑240份碎石进行混合，获得混凝土原料；取5‑15份的硅酸盐，获得填充材料；取5‑45份的降噪材料，并进行粉碎；取10‑60份的抑虫材料备用；将所述煤矸石原料、混凝土原料、填充材料、抑虫材料以及降噪材料按对应比例进行混合，技术效果是通过硅酸钙和煤矸石反应，形成硅酸盐凝胶，这种凝胶可以填充煤矸石中的孔隙，提高其致密性和硬度，从而增加混凝土的强度和耐久性，进而达到提高路基强度的目的。
