摘要:: 在砂土地区进行建(构)筑物的地基处理时,采用水坠砂技术可使砂土垫层的密实度和承载力达到设计要求。水坠砂工艺就是采用洁净的砂土替换原有砂土及腐质土,然后往基坑内灌水,使砂土借助水下渗的作用力重新排列组合,以达到密实的效果。文章以毛乌素沙漠地带建筑物和储罐基础施工为例,介绍了水坠砂技术的具体施工方法、注意事项和实施效果。
In foundation treatments of buildings or structures in sandy region, the sand compacted by down-seepage water technique is adoptable to enforce the compactness and bearing capacity of sand and soil cushion to meet the design requirements. In this technique, the original sand, soil and humus are replaced by clean sand; then water is poured into the base pit enabling sand rearranged and compacted by means of the water down-seepage force. Taking foundation constructions of buildings and storage tanks in Maowushu desert region as examples, this paper presents the construction method, key matters and implementation effectiveness of the process.
