| 摘 要： | 板下压浆是利用压浆设备将水泥、粉煤灰与水等材料按一定比例配制成混合料，用以填充扳下的空隙与孔洞，使之与板下基层粗粒料形成一个不溶解的坚硬块体，起到稳固和封堵怍用。工程实践表明，采用压降技术处理板底脱空的方法经济可行、简便实用、效果明显。

| Abstract: | Under-board mudjacking is indiscerptible hard mass that is formed by useing mudjack equipment to compound concrete, flying ash and water in proportion to commixture filled under-board interspace and cavity and composed to coarse aggregate under slab grass roots to the board bottom. Engineering practice indicates that it is economically feasible, brief and practical, having evident effect to adopt pressure drop technique to deal with bottomboard cavity. |
