Exploration and Study on Construction on Sandy Riverbed Using Hydraulic Impact and Digging Method |
| |
| Abstract: | By analyzing the common errors and consequences caused in the process of construction when using hydraulic impact and digging method, the corresponding advices are given. The operation management of segment refers to the principle of ＂short, quick, maintenance＂. Molding of cross-section adheres to the principle of ＂top-down, secondary molding＂. Using of high-pressure water gun applies the rules of ＂downstream, down slope＂. Determination of position where mud pumps stay applies ＂good to stabilization＂ rules. |
