毛石混凝土扩底墩基础,就是用毛石混凝土灌注、基础底面扩大的墩式基础,其埋置深度随荷载大小、土质情况以及地下有无防空洞或障碍物而定,一般可达2.5～15m。中心间距为2.4～3.9m,一般为一个房间的开间。它适用于公共建筑和居住建筑。一、扩底墩基础的特点 1.技术简易、施工方便。可用人工施工,不需复杂的施工机械。 2.安全可靠、确保质量。开挖土方呈
The foundation of the rubble concrete expansion base is the pier foundation filled with rubble concrete and the base of the foundation is enlarged. The depth of the pier is determined by the size of the load, the soil conditions, and whether there is an underground shelter or obstacles in the ground, generally up to 2.5 to 15m. . The center spacing is 2.4-3.9m, which is generally a room opening. It applies to public buildings and residential buildings. First, the characteristics of base expansion base 1. Simple technology, easy construction. Artificial construction can be used without complicated construction machinery. 2. Safe and reliable, ensure quality. Excavated earthwork
