| Abstract: | Because of the advantages and application fields,curved pipe jacking technology is paid more and more attention.The application of curved pipe jacking techniques all over the world is reviewed.Based on the two examples of "SS MOLE" and "Ultimate Method" curved pipe jacking techniques,the author introduces the suitable soil conditions,reasonable pipe diameter can be installed,application field and the minimum curved radius for curved pipe jacking technology.In order to solve the key and difficult problem of jacking loads calculating,an equation for the jacking loads calculation during curved section driving is given,as well there is an example shows the application of this equation. |
