1. Installation and Commissioning Method for Pump Station Gate

The installation accuracy of the embedded gate components is crucial for the gate to operate freely and effectively prevent water leakage. Moreover, adjustments cannot be made after the second-phase concrete pouring. Therefore, it is essential to strictly ensure that the installation accuracy meets the requirements of hydraulic specifications SLJ201-81 and PLJ201-80.

① Pre-construction preparation: a. Coordinate with civil construction to embed prefabricated iron in the reserved闸槽 of the concrete.

b. Prior to the installation of the gate embedment, all templates and debris in the reserved gate groove must be thoroughly cleared. C. Verify that the specifications and design requirements of the gate embedment are correct. D. Inspect the manufacturing quality of each component according to the manufacturing drawing for the embedment, and the allowable deviation should comply with the standard specifications. E. Correct any non-compliant gate embedments; those that cannot be corrected should be replaced. Non-compliant gate embedments must not be installed, as they cannot be adjusted after concrete pouring. F. Custom measuring tools. The gate embedment is the track for the gate's up and down movement, as well as the gate's water stop, requiring high precision. The embedment height is around 9 meters, and even a standard plumb bob is not sufficient. Therefore, custom templates and a 5kg plumb bob are necessary measures to ensure precision.
