Shield tail grease is very important to the tightness and durability of shield tail structure, and the consumption is very large as well as the construction has been accelerated. At present the related indexes of shield tail seal grease has no uniform standards, in the actual construction process for shield tail seal grease selection and testing still has certain blindness and subjectivity, is not conducive to the application of shield construction, contrary to the concept of energy saving and environmental protection. This study combined with the actual situation of domestic construction, the main technical indexes of the shield tail seal grease are summarized and elaborated the corresponding test methods, test speed and accuracy of the test of shield tail seal grease can effectively improve, to avoid unnecessary waste.
