| Abstract: | The hole excavation of the excavated belled piles of bridge works has such features as small cross-section, narrow working space, difficult blasting and high safety risks. Taking the construction of the excavated belled piles of No. 3 Zhanjia extra-large bridge on No. 6 contract section on Sansui - Kaili highway, the paper presents the drilling and blasting design of the excavation of the excavated belled piles, as well as the safety and quality control points of the excavated belled piles. |
