Description

Technical Field

[0001] The utility model belongs to the technical field of shield segment maintenance, and in particular relates to a shield segment pool maintenance device. Background Art

[0002] Shield segments are assembly components used in shield tunnel construction. They are used to construct the tunnel lining structure and are the innermost barrier of the tunnel. They are responsible for resisting soil pressure, groundwater pressure, and some special loads. Concrete needs to be fully moisturized in the early hardening stage to prevent excessive water loss and insufficient concrete strength. After production, shield segments need to be cured in a pool to provide a stable humidity environment and keep the concrete fully moist, thereby ensuring the strength and durability of the concrete and preventing cracking or insufficient strength of the concrete at an early age. Due to the large size of shield segments, only a small number of segments can be placed in the existing curing pool. If multiple segments need to be cured at the same time, a larger curing pool needs to be built, resulting in a larger occupied area. For example, patent number: CN201920953288.2 discloses a shield segment maintenance device. In this application, multiple maintenance devices are evenly placed inside the curing pool. The maintenance device consists of a curing platform, a supporting column, a shield segment annular placement rack, an elastic rubber sheet, and a pad. The segments can only be placed on the placement rack in a flat manner, and the space in the curing pool cannot be fully utilized, which leads to the problem of low shield segment maintenance efficiency.
