| 曲家屯特大橋旋挖鉆機(jī)施工及鉆具的改進(jìn)(51 卷) |
| 英文標(biāo)題 |
| Construction of Qujiatun super-large bridge by using rotating-drill boring machine and improved drill bit |
| 摘要 |
| 隨著旋挖鉆機(jī)的應(yīng)用范圍增大，成孔過程中鉆遇的地質(zhì)狀況更加復(fù)雜，高效成功施工鉆孔灌注樁對(duì)鉆具的選取要求也就更加嚴(yán)格。根據(jù)曲家屯特大橋所在區(qū)域凍土特性，結(jié)合摩擦樁施工量大，工期緊，環(huán)保和成本控制等要求，介紹鉆具的選擇和改進(jìn)。 |
