Solid waste foundation grouting material suitable for reinforcing bearing capacity of existing pile foundation and preparation method
The invention discloses a solid waste foundation grouting material suitable for reinforcing the bearing capacity of an existing pile foundation and a preparation method of the solid waste foundation grouting material. Red mud is adopted as a main material and cooperates with other multi-source solid waste, potassium hydroxide, carbide slag and quick lime are adopted as excitants, and the multi-source solid waste foundation grouting material suitable for reinforcing the bearing capacity of an existing pile foundation of reconstruction and extension engineering is prepared. The preparation method is simple, and the prepared grouting material is short in setting time, high in early strength, large in expansion coefficient, high in pile-soil interface cementing strength, suitable for reinforcing the bearing capacity of an existing pile foundation, capable of guaranteeing safety construction of highway reconstruction and extension projects, relieving solid waste stacking pressure and solving the problem of environmental pollution caused by red mud and suitable for large-scale popularization and application. And high-added-value comprehensive utilization of solid waste is promoted.
本发明公开了一种适用于既有桩基承载力加固的固废基注浆材料及其制备方法。采用赤泥为主体材料，并协同其他多源固废，以氢氧化钾、电石渣、生石灰为激发剂，制备适用于改扩建工程既有桩基承载力加固的多源固废基注浆材料。本发明的制备方法简单，所制备的注浆材料凝结时间短、早期强度高、膨胀系数大、桩土界面胶结强度高，适用于既有桩基承载力加固，可保证高速公路改扩建工程的安全建设，并且缓解固废堆存压力，解决赤泥对环境造成的污染问题，推动固废高附加值综合利用。
