“类刚性大直径高强水泥土桩”是广东省土木建筑学会地下工程专业委会2008年学术会议中五项推荐技术之一的“大直径(旋喷)搅拌桩”通过多年的工程实践研究及发展的延伸,近年已发展起“类刚性大直径水泥土桩+砼桩”组合的新桩型。其由新桩型构成的“砼加劲桩”基坑支护形式,具有抗侧刚度大、高强度、强穿透力、节省施工空间等特点已在广东多项基坑支护工程中得到成功验证,并取得良好的社会经济效益。
“Rigid Large Diameter High Strength Cement Piles ” is one of the five recommended technologies in the 2008 academic conference of Guangdong Civil Engineering Institute Underground Engineering Professional Committee “Large diameter (rotary jet) mixing pile ” Through years of Engineering practice and development of the extension of the development in recent years has developed “type of rigid large diameter cement pile + concrete pile ” combination of new pile type. It consists of a new pile-type “concrete stiffened pile ” foundation pit support form, with anti-side stiffness, high strength, strong penetration, saving construction space and other characteristics of a number of foundation pit in Guangdong support project Successfully verified, and achieved good social and economic benefits.
