【摘要】 “超流态混凝土灌注桩工艺”是在我国长螺旋钻机不断改型换代的基础上,利用现代钻机所能提供的良好机械性能,将一般长螺旋钻机只能进行干作业拓展到进行湿作业的施工新技术。而混凝土的制备和灌注,在施工中起到关键的作用。根据超流态混凝土灌注桩对混凝土的特殊要求,对组成超流态混凝土所需要的各种原材料的质量、级配以及配合比的设计进行了详细的论述。更多还原

【Abstract】 “Technology of Superfluid concrete pouring pile”is a new construction technique,which,on the basis of continuous modifying spiral jumper,has utilized modern drill to provide fine machinery performance,developing only from dry operation completed by original jumper to wet one completed by modern drill.Concrete preparation and pouring play a key role in construction.In terms of particular requirements of superfluid concrete pouring pile for concrete,the paper has a minute discussions on quality,grading and proportioning design of various raw and processed materials,which were required for composing the superfluid concrete.更多还原
