1前言目前水泥土桩一般分为三类:搅拌水泥土桩(喷浆、喷粉),旋喷水泥土桩(含定喷、摆喷),夯实水泥土桩。我们发明了一种新型的水泥土桩,它克服了搅拌水泥桩和旋喷水泥土桩依赖原地土的特点,也克服了夯实水泥土桩受地下水和深度的限制,尤其用于泥炭土等有机质含量高空隙比大含水量高的土层,有其独特的优越性。广泛适用于止水帷幕桩、复合地基桩(及母桩)、护坡桩(及母桩)、抗拔抗浮桩母桩等。2技术领域本发明属于建筑地基基础施工中的成桩,特别涉及一种新型水泥土桩及其成桩方法。用于止水帷幕桩、复合地
1 Foreword At present, soil-cement piles are generally divided into three categories: mixing cement-soil piles (shotcrete, dusting), spin-spray cement-soil piles (including fixed spray, swing spray), compacted cement soil pile. We invented a new type of cement-soil pile that overcomes the characteristics of the original cement-soil-pile and rotary-grouted cement-soil pile and overcomes the limitation of groundwater and depth of the compacted cement-soil pile, especially for peat soil Soil with high organic matter content and high water content has its unique advantages. Widely used in waterproof curtain curtain, composite foundation pile (and mother pile), slope protection pile (and mother pile), anti-floating anti-floating pile pile. 2 Technical Field The present invention belongs to the construction foundation pile foundation, in particular to a new type of cement pile and pile method. For water-stop curtain pile, composite ground
