近年来,随着经济的快速发展、科技的进步,公路桥梁建设也得到突飞猛进的发展。其中钻孔灌注桩是公路桥梁下部工程中常用的技术,它具有适应性强、成本低、施工便利等特点,因而广泛应用于公路桥梁等工程中。但是钻孔灌注桩属于隐蔽工程,应控制其施工质量,保证公路运输安全。
In recent years, along with the rapid economic development and the advancement of science and technology, the construction of highway bridges and bridges has also been making rapid progress by leaps and bounds. Among them, bored pile is a commonly used technique in the lower part of highway bridges. It has the characteristics of strong adaptability, low cost and convenient construction. Therefore, it is widely used in the engineering of highway bridges and so on. However, cast-in-place bored pile belongs to the concealed project, and its construction quality should be controlled to ensure the safety of road transport.
