Problems solved by technology

[0003] Due to the large size and weight of the horizontal dock door, large-scale handling 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 similar to a ship. Inject water into the dock door to level it. This method is convenient to adjust the balance of the dock door and has high stability. However, due to the large amount of bottom sealing and strict requirements, no water leakage is allowed, otherwise the dock door cannot float. During the process, it is necessary to open all the plates that are blocked at the bottom. Since all are underwater operations, the workload is heavy, the risk is high, and the construction period is long

Embodiment Construction

[0018] Below in conjunction with specific embodiment the present invention is described in further detail:

[0019] 1. After the dock door is manufactured on the tire frame, put the relevant equipment prepared for the dock door towing in advance, design a set of busbars according to the dock door to be towed, use seawater to seal the bottom hole of the dock door, and Partially modify the upper plane of the dock door, and at the same time seal all the exhaust holes of the tidal chamber on the top of the dock door, install the quick joint of the air pipe on the blocking plate, so that the air enters the tidal chamber from the air pipe, and cover the upper surface of the fixed water tank with a flange Install two sets of air pipe quick joints on the top, so that the air enters the fixed water tank from the air pipes. After completion, connect the air pipes to the quick joints, and connect the other end to the air busbar to form a sealed structure, and make the cables and the ball ...

Abstract

The invention discloses a flap gate floating control method; a flap gate is a P-shaped structural gate; before installation, the whole gate needs to be floated horizontally, and the gate is installed by being dragged to a specified position; floating conditions can be met through a certain adjustment method, all the holes on the upper surface of the gate need to be plugged and air inlets need to be added; a certain air is exhausted from a lower part by pumping different cabins of the gate, so that a certain air is left in the cabins of the gate, buoyancy is generated, the buoyancy which is generated by the gate is more than the self-weight of the gate; and the buoyancy of all the cabins is adjusted by controlling an air inlet valve, so that the balance is adjusted, and the gate meets floating requirements as expected.

Description

technical field [0001] The invention relates to a process method for installing a horizontal dock door. Specifically, the invention relates to a floating method for a horizontal dock door. By adjusting the gas in each cabin of the horizontal dock door, the dock door floats smoothly. Background technique [0002] The lying dock door is a P-shaped structure dock door, such as figure 1 As shown, it is 70 meters long, 6.6 meters wide, 14.6 meters high, and has a total weight of 1,400 tons. After the production is completed, it needs to be floated smoothly, and finally dragged to the designated location for installation. [0003] Due to the large size and weight of the horizontal dock door, large-scale handling 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 similar to a ship. Inject water into the dock door to level it. This method is convenient to adjust the balance...
