在水电、矿山、堤坝、码头和其它一些地下工程的建设上,对软基的加固和防渗堵漏,常常采用简易的花管造孔灌浆处理。花管造孔灌浆时,浆液常会沿管周外溢,有时甚至灌浆无法进行,这种现象。称为“冒浆”,不但造成浆液浪费,还影响灌浆质量。为了防止冒浆,目前采用地表浇注混凝土止浆板止浆。例如:广东“五八”围电排站基础防渗固结铬木素化学材料灌浆,河南午阳铁矿井筒开挖铬木素化学材料预注浆,都是采用地表浇注一层0.3~0.5米厚的混凝土止浆板止浆。吉林白山水电站围堰闭气的水泥—水璃玻灌浆,利用冬季的冻土层和洒水冻冰所形成的
In hydropower, mining, dams, piers and other underground construction, the reinforcement of soft ground and seepage control plugging, often using simple flower pipe hole filling grouting. Pipes made of pipe filling, the slurry often spills along the tube, and sometimes grouting can not be carried out, this phenomenon. Known as “fat slurry”, not only caused the slurry waste, but also affect the quality of grouting. In order to prevent the sloughing, the current use of concrete pouring grout stop slurry. For example: Guangdong “May 8” Peripherals base station seepage consolidation chrome lignin chemical grouting, Henan Wuyang iron ore well excavation chrome lignin chemical pre-grouting, are using the ground pouring a layer of 0.3 to 0.5 Thick concrete pulp to stop pulp.
