Curtain grouting for vertical antifouling barrier
The invention specifically discloses curtain grouting for a vertical antifouling barrier, which comprises the following raw materials: kaolin, a composite curing agent and water, and the weight ratio of water to (kaolin+composite curing agent) is 1.28-1.33. By selecting the raw materials and optimizing the mixing ratio, the fluidity and density of the prepared grouting meet the grouting construction requirements, the grouting technology is adjusted in a targeted mode, grouting is conducted through a point injection method, the grouting hole structure and the grouting sequence are optimized, the formed anti-seepage wall has the excellent anti-seepage effect, the permeability coefficient can reach 6.0 E-08 cm/s, in addition, through corresponding cooperation of the raw materials and the technology, the application range of the curtain grouting pressure is large, application limitation is effectively reduced, the comprehensive practicability is high, large-scale application and popularization can be achieved, and economic benefits are remarkably improved.
本发明具体公开一种垂直防污屏障用帷幕灌浆，帷幕灌浆包括以下原料：高岭土、复合固化剂、水，其中，按重量比计，水/(高岭土+复合固化剂)＝1.28～1.33。本发明通过对原料选取和配合比优化，制得的灌浆流动度、密度满足灌浆施工要求，并针对性调整灌浆工艺，以点喷射法灌浆，优化灌浆孔结构和灌浆顺序，形成的防渗墙具有优异的防渗效果，渗透系数可达6.0E－08cm/s，另外，通过原料与工艺对应协配，帷幕灌浆压力适用范围大，有效减低了应用限制，综合实用性强，可大范围推广应用，经济效益显著提高。
