Grouting material for reinforcing underground rectifying tower well wall protecting pipe and grouting method
The invention belongs to the technical field of reinforcing of wall protecting pipes of rectifying tower wells, and discloses a grouting material for reinforcing wall protecting pipes of underground rectifying tower wells and a grouting method. The invention provides a grouting material for reinforcing a wall protection pipe of an underground rectifying tower well. The grouting material is prepared from cement, silica fume, fly ash, gravel, ceramic waste, sulfonated asphalt powder, rubber powder, a defoaming agent, an exciting agent, a dispersing agent and water. The grouting material disclosed by the invention is relatively high in strength, the compressive strength of 7d can reach 14.8 to 15.6 MPa, and the compressive strength of 28d can reach 25.4 to 26.8 MPa. And the grouting material has certain impact toughness and can resist the influence of thermal expansion and cold contraction on the volume. The invention further provides a grouting method of the grouting material, special grouting pipe arrangement and a pressure grouting method are combined for grouting, and the fixing effect of the rectifying tower is further improved by adjusting grouting parameters.
本发明属于精馏塔井护壁管加固技术领域，本发明公开了一种地底精馏塔井护壁管加固用注浆材料及注浆方法。本发明提供了一种地底精馏塔井护壁管加固用注浆材料，包括水泥、硅灰、粉煤灰、碎石、陶瓷废料、磺化沥青粉、橡胶粉、消泡剂、激发剂、分散剂和水。本发明所述注浆材料的强度较高，7d的抗压强度可达14.8～15.6MPa，28d抗压强度25.4～26.8MPa。且注浆材料具有一定的冲击韧性，可以抵抗热胀冷缩对体积的影响。本发明还提供了所述注浆材料的注浆方法，将特殊的注浆管设置和压力注浆法结合进行注浆，通过调节注浆参数，进一步提高了精馏塔的固定效果。
