由于桩基础的施工在地底下,在施工过程中存在着很多不可预见的因素。同时,钻孔灌注桩的施工工艺复杂,施工环节较多,如果稍有不慎就会造成桩身承载力下降,甚至导致断桩的质量事故发生。因此,必须严格桩基施工过程的质量控制,确保成桩达到质量标准。通过探讨高速公路桥梁桩基施工技术要点,从中提出了相应的质量保证措施,以确保桥梁工程的顺利实施。
Due to the construction of pile foundation under the ground, there are many unforeseen factors in the construction process. At the same time, the construction process of bored piles is complex and there are many construction links. If a little carelessness is caused, the bearing capacity of the piles will be reduced and even lead to the quality accident of broken piles. Therefore, the quality control of pile foundation construction process must be strictly ensured to ensure that the pile reaches the quality standard. By discussing the key points of construction technology of highway bridge pile foundation, corresponding quality assurance measures are put forward to ensure the smooth implementation of bridge engineering.
