High polymer cement composite grouting material for water-rich loess roadbed void and high-pressure jet grouting method thereof
The invention belongs to the technical field of roadbed engineering, and particularly discloses a high polymer cement composite grouting material for water-rich loess roadbed void and a high-pressure rotary jet grouting method of the high polymer cement composite grouting material. The high polymer cement composite grouting material for water-rich loess roadbed void is mainly composed of toluene diisocynate, sorbitol-based polyether polyol, castor oil polyoxyethylene ether, triethanolamine, glycerin, cement, red mud and water. The high-pressure jet grouting method of the high polymer cement composite grouting material for water-rich loess roadbed void comprises the following steps: firstly, detecting by a ground penetrating radar to obtain the specific position, depth and width of a water-rich roadbed void disease; and then the high polymer cement composite grouting material is rapidly poured into the disease position of the water-rich loess roadbed at high pressure through a grouting pump of a high-pressure jet grouting machine. The high polymer cement composite grouting material has the characteristics of rapid hardening, high elasticity, low permeability and the like, and rapid pile forming and loess roadbed void repairing can be realized through high-pressure rotary jet grouting.
本发明属于路基工程技术领域，具体公开了一种富水黄土路基脱空用高聚物水泥复合注浆材料及其高压旋喷注浆方法。该富水黄土路基脱空用高聚物水泥复合注浆材料主要由甲苯二异氰酸酯、山梨醇基聚醚多元醇、蓖麻油聚氧乙烯醚、三乙醇胺、甘油、水泥、赤泥和水组成。所述的富水黄土路基脱空用高聚物水泥复合注浆材料的高压旋喷注浆方法为：首先由探地雷达探测得到富水路基脱空病害的具体位置以及深度和宽度，然后通过高压旋喷机灌浆泵将高聚物水泥复合注浆材料高压快速灌入富水黄土路基病害处。该高聚物水泥复合注浆材料具有快硬性、高弹性、低渗透性等特点，通过高压旋喷注浆可实现快速成桩并修复黄土路基脱空。
