抽芯检测在长兴县虹溪中学综合楼水泥搅拌桩测试中的应用

Application of core-pulling detection in cement mixing pile test in Changxing County Rainbow Creek Middle School

抽芯检测是利用小口径岩芯回转钻机在桩体中抽芯取水泥土样,检查桩体均匀性和连续性,并进行抗压强度试验,以检验搅拌桩的桩身质量情况,并进行复合地基承载力估算的一种桩基检测方法。

Core pulling detection is a method of pile foundation detection,which use small diameter core rotary drilling rig in the pile body core pulling cement soil samples,checking the uniformity and continuity of piles,Through the compressive strength test measuring the pile body quality,estimating the composite foundation bearing capacity.
