Foaming low-carbon cement composite grouting material for loess roadbed and pavement subsidence and application of foaming low-carbon cement composite grouting material
The invention discloses a foaming low-carbon cement composite grouting material for loess roadbed and pavement subsidence and application of the foaming low-carbon cement composite grouting material. The grouting material comprises the following components in parts by mass: 10-20 parts of circulating fluidized bed fly ash, 10-20 parts of circulating fluidized bed furnace bottom slag, 50-60 parts of low-carbon cement, 10 parts of high-calcium bauxite and 5-10 parts of oily polyurethane. The prepared foaming low-carbon cement composite grouting material for loess roadbed and pavement subsidence has the advantages of micro-expansion (foaming) characteristic, excellent mechanical property, ultralow permeability coefficient, excellent durability, environmental protection and the like. When the grouting agent is applied to grouting treatment of loess subgrade pavement subsidence, the loess subgrade pavement subsidence can be rapidly repaired, the grouting construction period is shortened, water in a loess slope sinkhole is prevented from permeating into the loess subgrade, a waterway channel between the sinkhole and the loess subgrade is blocked, and the loess subgrade pavement can operate safely and stably for a long time; and the service life of the expressway in the loess area is prolonged.
本发明公开了一种黄土路基路面沉陷用发泡低碳水泥复合注浆材料及其应用。该注浆材料的组成包括10‑20质量份的循环流化床粉煤灰、10‑20质量份的循环流化床炉底渣、50‑60质量份的低碳水泥、10质量份的高钙铝矾土、5‑10质量份的油性聚氨酯。本发明制备的黄土路基路面沉陷用发泡低碳水泥复合注浆材料具有微膨胀(发泡)特性、优异的力学特性、超低的渗透系数、优异的耐久性及绿色环保等优点。将其应用于黄土路基路面沉陷的注浆处治，可快速修复黄土路基路面沉陷病害，缩短注浆的施工周期，防止黄土边坡落水洞水分渗入黄土路基，阻隔落水洞与黄土路基的水路通道，使黄土地区路基路面长期安全稳定的运营，延长黄土地区高速公路的使用寿命。
