近年来我国桥梁建设的迅猛发展,桥梁建设的规模、跨径、结构形式以及荷载等级的逐渐加大,灌注桩基础由于具有适应于各类土层且具有较高的承载能力,广泛应用于桥梁工程建设当中,但由于灌注桩具有上层土层软弱,适宜的持力层较深,桩基础埋置深度大属于隐蔽工程,施工包括多个环节,工艺复杂等特点,因此灌注桩的施工质量也不容易控制,是影响桥梁施工质量的关键环节,因此保证灌注桩的施工质量是关系整个桥梁结构安全和质量的主要问题之一,对于一些常见的施工质量问题如果采取一定合理的措施很多问题是可以避免的,本文对灌注桩施工常见的质量问题及防治方法做以探讨。
In recent years, with the rapid development of bridge construction in China, the scale, span, structure and load level of bridge construction gradually increase. Because of its adaptability to various soil layers and its high carrying capacity, the pile foundation is widely used in bridges However, due to the fact that the bored piles have the characteristics of weak upper soil layer, suitable deep holding layer and deep embedment of the pile foundation which are concealed projects, the construction includes many aspects and the process is complex. Therefore, the construction quality of the bored pile Not easy to control, it is the key link that affects the quality of bridge construction. Therefore, to ensure the construction quality of cast-in-place piles is one of the main problems that affect the safety and quality of bridge structure. For some common construction quality problems, some reasonable measures are taken if Can be avoided, this article on the common quality problems of cast-in-place pile construction and prevention methods to do to explore.
