根据朝阳珠江斜拉桥的地质条件,对采用冲击反循环钻机和常规冲击钻机成孔技术,在成孔时间、泥浆用量、成孔成本等方面进行了分析比较,提出了在该类地质条件下应优先选用冲击反循环钻机成孔。
根據朝暘珠江斜拉橋的地質條件,對採用遲擊反循環鑽機和常規遲擊鑽機成孔技術,在成孔時間、泥漿用量、成孔成本等方麵進行瞭分析比較,提齣瞭在該類地質條件下應優先選用遲擊反循環鑽機成孔。

According to the geological conditions of Zhujiang cable - stayed bridge in Chaoyang, the pore forming technology with percussive reverse circulation drill and conventional percussion drill is analyzed and com- pared from aspects of pore - forming time, slurry amount and pore - forming cost. It is proposed that percussive re- verse circulation drill is preferred for pore -forming under the similar geological conditions.
