Flow state filling material of collapsible loess and sandy gravel aggregate
The invention discloses a collapsible loess and sandy gravel aggregate filling material which is formed by jointly mixing aggregate composed of collapsible loess and sandy gravel, a curing agent, an additive and water, and the aggregate is composed of fine aggregate and coarse aggregate. The mixed filling material with the collapsible loess and the sandy cobbles as the main body is provided by combining raw materials such as the collapsible loess and the sandy cobbles which are common in northwest regions, wherein the collapsible loess and the sandy cobbles are weak in shrinkage performance, low in consolidation settlement, free of collapsibility, low in permeability and low in price, and the bearing capacity of the mixed filling material meets the requirements in the backfilling process.
本发明公开了一种湿陷性黄土与砂卵石集料填筑材料，由湿陷性黄土和砂卵石构成的集料、固化剂、外加剂、水共同混合组成，所述集料由细集料和粗集料组成。本发明结合西北地区较为常见的湿陷性黄土、砂卵石等原材料，提出了一种在回填过程中收缩性能弱、固结沉降低、无湿陷性、渗透性能低、承载能力满足要求且价格低廉的以湿陷性黄土和砂卵石为主体的混合填筑材料。
