灰砂桩即生石灰和粗砂为填充料的混合桩体,在处理软弱地基提高地基承载能力方面,具有开挖土方少,施工速度快,造价低并能大幅提高地基土承载力等特点,使得它与其它挤密桩逐步推广使用。用灰砂桩处理建筑物下局部或整片软弱土层效果显著。灰砂桩施工方法较简单,成孔机具可?
Lime and sand piles are mixed piles of quicklime and coarse sand as fillers. They have the characteristics of less excavation earthwork, faster construction speed, lower construction cost, and can greatly increase the bearing capacity of foundation soil in terms of handling weak foundations to improve the bearing capacity of foundations. It is gradually used in conjunction with other compaction piles. The use of lime sand piles to treat the local or entire sheet of soft soil under the building is significant. Lime sand pile construction method is relatively simple, drilling equipment can be?
