High polymer composite grouting material for bridgehead water-rich roadbed void and double-liquid grouting method thereof
The invention discloses a high polymer composite grouting material for bridgehead water-rich roadbed void and a double-liquid grouting method thereof. The composite grouting material is prepared from polymethylene polyphenyl polyisocyanate, toluene diisocynate, polyether polyol 2000LM, kitchen waste oil, industrial triethanolamine, propylene glycol, n-pentane, cement, steel slag micropowder, slag, water and the like. The double-liquid grouting method comprises the steps that firstly, the specific area and depth of a bridgehead water-rich roadbed disease are detected by means of a ground penetrating radar and a high-density electrical method, the deepest position of a void or water-rich area serves as the depth of a grouting hole, and two kinds of liquid are poured into the disease position at the same time through a cement grouting pump and a polyurethane high-pressure grouting pump. The grouting material has excellent elasticity, durability and compressive strength and ultra-low permeability coefficient, and the double-liquid grouting method can realize non-excavation type rapid repair of bridgehead water-rich roadbed void and can rapidly detect a roadbed water-rich or void area, so that a bridge operates safely and stably for a long time, and the service life of the bridge is prolonged.
本发明公开了一种桥头富水路基脱空用高聚物复合灌浆材料及其双液灌浆方法。该复合灌浆材料由多亚甲基多苯基多异氰酸酯、甲苯二异氰酸酯、聚醚多元醇2000LM、餐厨废弃油、工业三乙醇胺、丙二醇、正戊烷、水泥、钢渣微粉、矿渣、水等组成。所述的双液灌浆方法为：首先借助探地雷达和高密度电法探测得到桥头富水路基病害的具体区域和深度，以脱空或富水区域最深处为注浆孔深度，通过水泥注浆泵和聚氨酯高压灌浆泵同时将两种液体灌入病害处。该灌浆材料具有优异的弹性、耐久性和抗压强度、超低的渗透系数，该双液灌浆方法可实现桥头富水路基脱空的非开挖式快速修复并可快速探测路基富水或脱空区域，使桥梁长期安全稳定的运营，延长桥梁的使用寿命。
