Large racing track soft soil foundation filling foam light soil material, preparation method and application
The invention discloses a large racing track soft soil foundation filling foam light soil material as well as a preparation method and application thereof. The foam light soil material is prepared from the following raw materials in parts by weight: 30-40 parts of cement, 30-40 parts of mineral powder, 30-50 parts of fly ash, 0.1-0.5 part of an instant mixing type composite reinforced foaming agent, 0-0.03 part of a foam toughening agent and 60-70 parts of water. The use amount of the cement is small, the internal hydration heat is low, and cracking of the foam light soil caused by hydration temperature rise is avoided; a small amount of cement reduces the shrinkage rate of the foam light soil, increases the volume stability, and is beneficial to improving the durability of the foam light soil; by using a large amount of mineral powder and fly ash, the volume stability and the later strength of the foam light soil can be improved. A vehicle-mounted mobile intelligent control system is adopted, so that the construction quality of the foam light soil is guaranteed; the method is suitable for large-volume and large-area rapid construction; by means of early-stage modeling refinement and layered and partitioned pouring, multi-point construction and ordered pouring are facilitated.
本发明公开了大型赛道软土地基填充泡沫轻质土材料、制备方法及应用，泡沫轻质土材料包括以下重量份的原料制成：水泥：30~40份，矿粉：30~40份，粉煤灰：30~50份，即混型复合增强发泡剂0.1~0.5份，泡沫增韧剂0~0.03份，水60~70份。本发明水泥的用量少，内部水化热低，避免因水化温升而导致泡沫轻质土开裂；少水泥用量降低了泡沫轻质土的收缩率，增加了体积稳定性，有利于提高泡沫轻质土的耐久性；大量使用矿粉和粉煤灰，还有利于提高泡沫轻质土的体积稳定性和后期强度。采用车载移动式智能控制系统，有利于保证泡沫轻质土施工质量；适应于大体积、大面积的快速施工；通过前期建模细化，采用分层分区浇注，便于多点施工和有序浇筑。
