广州华南快速路桥基钻(冲)孔灌注桩施工技术
Construction Technique of Drilling (Wash) Bored Piles in Huanan Highway in Guangzhou City
【摘要】 广州华南快速路工程有若干座桥梁,采用钻(冲)孔灌注桩基础,共112根,桩径 1 0、1 5及1 8m三种,桩长44~51m,由于地质条件变化大,部分地层中有断层夹泥与溶洞等不良地质,主桥桩基位于深约8m的水中,具有一定的施工难度。对其施工方法与技术措施作了介绍。
【Abstract】 The paper introduces Hua’nan Highway engineering in Guangzhou city. The project includes several bridges, in which totally 112 pieces drill (wash) bored piles, with 1.0 m, 1.5 m and 1.8 m in diameter, 44 ~ 51 m in length, were adopted as the foundations. Because geological conditions varies largely, some strata contain mud layer and Karst cave etc. and what’s more, main bridge locating in water at the depth of 8 m, some difficulties were dealt with.
