等能量、等变形夯扩挤密矸石桩在处理煤田塌陷区地基中的应用

Application of Equal Energy,Equal Deformation Tamping and Expansion Gangue Pile Treating Foundation in Coal Mining Collapse Area

等能量、等变形夯扩挤密矸石桩是一种地基加固新技术。该方法既有挤密作用,又能加固杂填土,桩身材料采用矿区生产的垃圾废物煤矸石,成本低廉,施工速度快,施工工艺简单,振动及噪声影响小,对环境无污染,经济效益和社会效益显著。工程实践证明,该技术十分适合软土地基加固处理。

Equal energy, equal deformation tamping and expansion gangue pile is a new strengthening method, which not only has the effect of tamping and expansion, but also strengthens complex earth-fill. The material of pile body is a water coal gangue, which has many characteristic, including low cost, high efficiency, easy construction technique, low vibration and noise, non-pollution for environment, and conspicuous economic benefit and social benefit. Practical construction shows that equal energy, equal deformation tamping and expansion gangue pile is very suited for strengthening soft foundation.
