Foamed cement soil slurry for backfilling of fat building trough and construction process
The invention relates to foamed cement soil slurry for backfilling of a fat building trough. The foamed cement soil slurry comprises the following components in parts by weight: 20-80 parts of clay or silt, 20-80 parts of brick slag or concrete slag, 30-70 parts of sandy soil, 10-20 parts of cement, 0.05-0.2 part of a powdery foaming agent, 50-90 parts of water and 0-0.2 part of an additive (namely a foam stabilizer). All the components are put into a stirrer according to the above parts by weight and are uniformly stirred to obtain a mixture, then a discharge port baffle is opened, and the mixture is conveyed by a conveying pump and poured into a fat building trough for backfilling. According to the invention, the effect of increasing a volume can be achieved by adding the proper foaming agent, the workability of the slurry is good, the strength, permeability, subsidence prevention and other properties of the slurry can meet requirements for filling of the fat trough, cost is reduced exponentially, efficiency is improved exponentially, and a construction period is shortened exponentially.
一种建筑肥槽回填用发泡水泥土浆液，包括的成分及其重量份数为：黏土或粉土20~80份，砖渣或砼渣20~80份，砂类土30~70份，水泥10~20份，粉状发泡剂0.05~0.2份，水50~90份，外加剂（即稳泡剂）0~0.2份；按照上述重量份数将上述所有成分放入搅拌机搅拌均匀获得拌合料，然后打开卸料口挡板，用输送泵将该拌合料输送并浇筑到欲回填的建筑肥槽内。本发明通过加入合适的发泡剂均能实现体积增大的效果，其和易性好，无论强度、渗透性、防沉陷等性能同样能满足填筑肥槽的需要，成本成倍降低，效率成倍提高，工期也成倍缩短。
