钢筋砼预制桩,在施打沉桩过程中,常见的有预制桩被打坏、打斜、沉桩达不到设计要求、桩顶位移、邻桩隆起、接桩处松脱开裂等现象。而这些问题的出现,主要是由于预制桩的质量、地基土层的变化和施工技术等原因造成的。因此,这些现象的出现,是随机的、复杂的,应根据具体情况作具体分析,并及时处理。 Reinforced concrete prefabricated piles, in the process of sinking piles, prefabricated piles are often broken, beaten oblique, piled up less than the design requirements, pile top displacement, adjacent piles bulge, then the pile at the Department of loosening and cracking and so on. The emergence of these problems is mainly due to the quality of prefabricated piles, changes in foundation soil and construction technology and other causes. Therefore, the appearance of these phenomena is random and complicated and should be analyzed concretely and dealt with in time.
