Problems solved by technology
[0003] The maintenance of existing shield segments is mostly similar to that of other prefabricated concrete parts. The curing is completed by soaking in the curing solution. However, since the application scenarios of shield tunneling segments are more special than those of conventional The environment has higher requirements, and the conventional concrete prefabricated parts maintenance method is not suitable for the maintenance of the shield segment. The water quality deteriorates rapidly, and the impurity in the curing solution cannot be removed in time, which makes the overall pH easy to fluctuate, which makes the shield tunnel after curing The color of the segment is different, and the excessive proliferation of fungi and algae in the curing solution is likely to affect the mechanical properties of the shield segment

The invention relates to the technical field of shield segment maintenance, in particular to a shield segment maintenance method. Through circulation of maintenance liquid, impurities, fungi and algae in the maintenance liquid can be removed in time after the maintenance liquid is subjected to precipitation, filtration and sterilization treatment, so that the whole maintenance liquid can be dynamically balanced, the pH values and the temperature in curing units tend to be consistent, the curing quality is ensured, and the problems that the curing mode of a shield segment is mostly similar to that of other concrete prefabricated parts, the curing is completed by soaking the shield segment in the curing liquid, the application scene of the shield segment is more special than that of the concrete prefabricated parts, the shield segment has higher requirements on the curing environment, a conventional concrete prefabricated part curing mode is not suitable for curing the shield segment, the water quality degradation speed of the conventional concrete prefabricated part curing mode is high, the impurities in the curing liquid cannot be removed in time, consequently, the overall pH is prone to fluctuation, the color of the cured shield segment is different, meanwhile, excessive proliferation of the fungi, the algae and the like in the maintenance liquid easily affects the mechanical performance of the shield segment are solved.
Description
technical field [0001] The invention relates to the technical field of shield tunneling segment maintenance, in particular to a shield tunneling segment maintenance method. Background technique [0002] The shield segment is the main assembly component of shield construction and the innermost barrier of the tunnel, which bears the role of resisting soil pressure, groundwater pressure and some special loads. The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel. The existing production of shield segments mainly includes steel skeleton forming, concrete pouring and vibration, outer arc surface water collection, steam curing and water curing. After the shield segment is processed, it needs to be soaked in a curing pool for a period of time by an overhead crane to improve the durability an...
