Slurry for quicksand stratum underground diaphragm wall
The invention relates to slurry for a quicksand stratum underground diaphragm wall. The slurry comprises the following components: 90-140 g/L of bentonite, 3.5-8.0 g/L of a slurry treating agent, 0.02-0.8 g/L of polyacrylamide, and the balance of water. Specifically, the bentonite is preferably calcium bentonite, and the slurry treatment agent comprises sodium carbonate and carboxymethyl cellulose. The slurry provided by the invention comprises the following components: bentonite, a slurry treating agent, polyacrylamide and water, wherein the bentonite is used as a main slurry preparation material of the slurry, so that the density and viscosity of the slurry can be effectively improved, a compact mud cake with low permeability can be formed, the water loss of the slurry can be reduced, and the stability of a tank wall can be effectively improved by using the slurry in a construction process.
本发明涉及一种用于流砂地层地下连续墙的泥浆，该泥浆中各组分及含量如下：膨润土90g/L～140g/L、泥浆处理剂3.5g/L～8.0g/L及聚丙烯酰胺0.02g/L～0.8g/L，余量为水。具体地，该膨润土优选为钙基膨润土，泥浆处理剂包括：纯碱及羧甲基纤维素。本发明所提供的泥浆是其组分包括：膨润土、泥浆处理剂、聚丙烯酰胺及水，膨润土作为泥浆的主要配浆材料，能够有效提高泥浆密度和粘度，能够形成低渗透率的致密泥饼，降低泥浆失水量，在施工过程中使用该泥浆可有效改善槽壁的稳定性。
