Flap gate float control method

Abstract

The invention discloses a flap gate float control method. The method mainly includes steps: opening a tide compartment valve and a fixed water compartment valve, filling water into a water pool, and stopping water filling when a water inlet of a tide compartment and a water inlet of a fixed water compartment are submerged; filling the fixed water compartment with compressed air, and stopping filling and closing the fixed water compartment valve when the internal air pressure of the fixed water compartment reaches 1.1-1.2 times of barometric pressure; continuing injecting water into the water pool, and stopping water injection when a dock gate starts to leave the ground on one side of the fixed water compartment; charging compressed air into the tide compartment, and when the top surface ofthe dock gate is kept horizontal, stopping air charging and closing the tide compartment valve. By adoption of the method, dock gate floating can be realized without hole sealing of the bottom of thedock gate, and accordingly convenience in consigning is achieved.

Description

technical field [0001] The present invention relates to a dock door, in particular to a floating control method for a lying dock door. Background technique [0002] The horizontal dock door is a P-shaped structure dock door, which needs to be floated smoothly after fabrication, and finally dragged to the designated location for installation. Due to the large size and heavy weight, large equipment is used for transportation, and the conditions are limited. The traditional method is to block all the holes at the bottom of the dock door to make it float, and to adjust the top surface to the level by injecting water from the top into the dock door. This method has high stability, but due to the large amount of sealing at the bottom , and the requirements are strict, no water leakage, otherwise the dock door will not be able to float, and all the bottom sealing plates need to be opened during the installation process, because all are underwater operations, and the workload is he...

The traditional method is to block all the holes at the bottom of the dock door to make it float, and to adjust the top surface to the level by injecting water from the top into the dock door. This method has high stability, but due to the large amount of sealing at the bottom , and the requirements are strict, no water leakage, otherwise the dock door will not be able to float, and all the plates that are blocked at the bottom need to be opened during the installation process, because all are underwater operations, and the workload is heavy, the risk is high, and the construction period is long
