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

Embodiment Construction
[0021] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0022] Such as figure 1 Shown is a three-dimensional view of the lying dock door. It can be seen from the figure that there are openings on the top and bottom of the dock door. Some openings on the top will be the exhaust ports mentioned later, and some openings on the bottom will be the exhaust ports mentioned later. water inlet. In the prior art, generally the opening at the bottom, i.e. the water inlet, is blocked, but not in the present invention.
[0023] Such as figure 2 Shown is a cross-sectional view of a lying dock door, figure 2 4 compartments are shown in the figure, respectively tidal compartment 1, fixed floating compartment 3, fixed water compartment 2 and operating compartment 4, which are the basic structures of the recumbent dock doors (they are all in the use process of the dock doors have a role, and will not be ex...

The invention discloses a method for controlling the floating of a recumbent dock door. The method mainly includes the following steps: opening the valve of the tidal chamber and the valve of the fixed water tank, and injecting water into the pool; When the nozzles are all submerged, stop water injection; fill the fixed water tank with compressed air, and when the air pressure in the fixed water tank reaches 1.1 to 1.2 times the atmospheric pressure, stop inflating and close the valve of the fixed water tank; continue to inject water into the pool, when the docking When the door starts to leave the ground on the side of the fixed water tank, stop the water injection; fill the tidal tank with compressed air, and when the top surface of the dock door remains horizontal, stop the inflation and close the valve of the tidal tank; When the bottom of the door is sealed, the floating of the dock door is realized, which is convenient for consignment.
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...
