There are many problems in steel sleeve launching and receiving of shield without end soil consolidation; and the safety and economy of shield launching and receiving should be guaranteed. As a result, the performances of steel sleeve, i. e. stiffness, tightness, leakproofness and pressure holding capacity, and key technologies are analyzed and studied by comparative analysis, simulation calculation and engineering test. The steel sleeve equipment is improved and the antiforce adjusting device and the threeway pipe device are adopted. [JP2]The engineering practice shows that the improved steel sleeve can ensure the safety and efficiency of shield launching and receiving without end soil consolidation.
