T/CHES 38-2020 Hydraulic gate system manufacturing, installation and acceptance specifications
Basic Information
Scope
Main technical content: This specification stipulates the manufacture of the gate leaves, pre-embedded parts, and bottom shaft hinge seats of the hydraulic gate system; the manufacture of support rods and locking devices; the manufacture and testing of hydraulic and electronic control systems; packaging and transportation; installation and commissioning; and acceptance. This specification is applicable to medium- and small-scale water conservancy projects, in which the gate system is opened and closed by hydraulic cylinders, supported during closing, and the gate leaves rotate around the bottom shaft. The water-retaining height is ≤5m, and the width of a single gate leaf is ≤12m. For gate systems with a water-retaining height >5m or a single gate leaf width >12m, special technical demonstrations and model test studies should be conducted before using this specification as a reference. The support rods and locking devices mentioned in this specification can be selected according to the needs of the project.
