注浆就是将液体介质压注到地层中,充填土壤的孔隙和岩层的裂隙,作为一种工程实践已有一百年的历史了。浆液被压注到空隙中后固化或形成凝胶体,起到堵水和加固的目的。 通常将水泥和粘土类注浆材料称为“一般注浆材料”,而将其他注浆材料称为“化学注浆材料”。确切地说,应将注浆材料分为颗粒型注浆材料和溶液型注浆材料,因为这样的分类很明显地说明了两类注浆材料的主要区别。
Grouting is the liquid medium pressure injection into the formation, filling the pores of soil and rock fissures, as a project has been a hundred years of history. Slurry is injected into the gap after curing or gel formation, play a blocking water and reinforcement purposes. Cement and clay grouting materials are commonly referred to as “normal grouting materials,” while other grouting materials are referred to as “chemical grouting materials.” Specifically, the grouting material should be divided into granular grouting material and solution grouting material, as such classification clearly shows the main difference between the two grouting materials.
