问题1简单举例说明结构物基础工程的施工方法及其所使用的机械.在施工注意事项中,您认为哪些事项比较重要,简单叙述之.解答:结构物的基础可分为直接基础、桩基础和沉箱基础三种.直接基础也称底座基础,该基础一般用于几乎不需埋置深度的基础,如山区地带岩基接近地表,挤紧的砂层、浅砂砾层和预先开掘量较小的地基.桩基础用于平原建筑结构物,使用十分广泛,有预制桩和现场桩两种.使用预制桩,根据不同材料,分为木桩、RC 桩、PC 桩和钢桩等施工方法,根据不同打进方法,又可分为利用打击力的打入施工法、射水沉桩施工法、压入式施工法和振动打击施工法.利用打击力的打击施工法,有使用落锤
Problem 1 briefly illustrates the construction method of the foundation project of the structure and the machinery used. What do you think are more important in the construction precautions, and simply describe it? Solution: The foundation of the structure can be divided into direct foundation and pile foundation. Three types of caissons are based. The direct foundation is also called the base foundation. This foundation is generally used for foundations that do not need to be buried in depth. For example, in the mountainous area, the rock foundation is close to the surface, the compacted sand layer, shallow gravel layer and pre-dig volume are small. The foundation of the pile is used in the construction of plain buildings and is widely used. There are two kinds of prefabricated piles and field piles. Using prefabricated piles, according to different materials, it is divided into construction methods such as wooden piles, RC piles, PC piles and steel piles. According to different methods, they can be divided into hitting construction method using impact force, jetting water-sinking construction method, press-in construction method and vibration-suppressing construction method.
