振动沉管灌注桩,可应用于各种土层中,尤其是下卧土层起伏多变的地基。振动沉管灌注桩按作用分为挤密桩、摩擦桩和端承桩,实际建筑的灌注桩三者综合利用的较多,施工设备比较简单,其成孔、混凝土的关注、成桩都处于隐藏状态。由于施工控制不利,会造成桩身质量缺陷,承载能力低于设计要求。因此,对桩的质量检测和质量通病
Vibration sinking pipe filling pile, can be applied to all kinds of soil, especially the fluctuating foundation soil. The vibrating pipe sinking piles are divided into the compaction piles, the friction piles and the end bearing piles according to their functions. The actual construction of the piles is comprehensively utilized, and the construction equipment is relatively simple. Hidden state Due to the construction control is unfavorable, it will cause the quality defect of the pile, the carrying capacity is lower than the design requirements. Therefore, the pile quality inspection and quality of common problems
