Riverside Police.

At two o'clock in the afternoon, the colorful flags of the Changlong Dockyard construction site were waving, and the gongs and drums were loud!

As early as last year at the inaugural meeting of Linghai Economic and Technological Development Zone, Secretary Ye asked the cadres of the development zone and the heads of enterprises to race against time to learn "Shenzheng Speed" and "Pudong Speed".

After a year of intensive construction, the main project of Changlong Dock was completed one and a half months ahead of schedule.

Not only Secretary Ye, Mayor Qian and other leaders of Linghai City came to participate in the completion ceremony of the main body, but even Deputy Mayor Qin of Binjiang City who was in charge of the industry came.

Leaders from the Harbor Supervision Bureau, Binjiang City Planning Commission, Binjiang Customs, Binjiang Entry-Exit Border Inspection Station, Health Quarantine, Commodity Inspection and other departments were also invited to attend the completion ceremony.

As a cadre of the development zone who contacts so many law enforcement units on the river and is in charge of the Changlong Dock project, Han Yu can't be lazy or dodge leisurely. He has to help receive leaders from various units on the river, and he is as busy as Tang Wentao, the deputy director of the management committee. .

Boss Wang of Changyu Shipyard, Boss Wu of Linghai Shipyard, and Lao Ding, Vice President of Changlong Dock (Wharf) Co., Ltd. were the most excited. They still wore suits and leather shoes on their chests like a bridegroom in such a cold day. Dahonghua is busy introducing the construction of the dock to the leaders.

The Chief Engineer of Navigation Engineering Bureau, who is responsible for the design and construction of the dock, is being interviewed by Binjiang TV Station, Linghai TV Station and other media.

The gray-haired old engineer was not at all stage-frightened when facing the camera, and said happily: "The dock is a drainage and pressure-reducing dock built directly on the clay foundation. It is the first dock wall built in Jiangnan Province without considering its own anti-skid Stable, [-]-ton dock with large buttress walls.

The effective length of the dock is 300 meters, the width is 82 meters, and the depth is 14.3 meters. It can be used to carry the hull of more than [-] tons, or to close up large ships built in sections.If the resources in the dock are tight, a separation wall can be made and used as two docks or even three docks.

When Deputy Mayor Qin, Secretary Ye and other leaders, accompanied by Deputy Mayor Shen, Boss Wang, Boss Wu, Yuju and others walked from the embankment where the ceremony was held to the gate of the floating box dock, they looked at the dock from the ruler. The water is already forty centimeters deep.

Boss Wang and Boss Wu complained more than once. If they knew it was so simple and built it themselves, they could save at least millions.

Just when Guo Weitao thought to himself what kind of shipyard this was, and it didn't even look like a shipyard, Secretary Ye, under the humility of Deputy Mayor Qin and Bureau Tang of the Harbor Supervision Bureau, announced to fill the shipyard with water amidst a burst of warm applause.

It has been two and a half months since Guo Weitao was transferred to the No. [-] Squadron of the Marine Police as an assistant instructor. Everything feels so unreal.

In other words, if someone who knows water firefighting commanded the rescue, the fire would definitely be extinguished and the passenger ship would not sink.However, the fire officers and soldiers on the shore did not know how to spray water to put out the fire, which caused the passenger ship to lose its balance and capsize due to too much water injection.

But they were just complaining behind their backs. After all, they had never built or even seen a floating box-type dock door before, and they dared not take such a large investment and directly related to safety as a trifling matter.

Under the command of Han Xiangning, director of the Linghai Port Supervision Department who guaranteed the water injection test, the tugboat anchored in the waters about one kilometer away from the dock gate.

Han Yu looked at the dock gate with his head, and said in a low voice: "This is a water injection test. Anything can happen. Safety is more important than anything else. Don't worry about it if you don't stay here and watch."

The water content of this dock is close to the flow limit, and the void ratio is large. It is the first time in China to build a dock directly on the clay foundation.Because we have taken a series of measures in structural design and construction, the dock structure is lighter and more economical.

There was an offshore passenger ship owned by the Maritime Bureau. The cabin caught fire when it was in port. The crew transferred the passengers ashore in time.

The old engineer of the Navigation Engineering Bureau smiled and explained: "The side of the dock facing the river is 82 meters wide, but the pontoon-type dock door is only 66 meters long. In the dock wall, although we have confidence in our design and construction, just like Director Xiao Han said, we must consider safety when doing water injection tests."

All in all, this expensive pontoon-type dock door has all the inherent characteristics of a ship. It is a [-]-ton ship with a strange appearance.

There are only dozens of bollards on the east, west, and north sides of the dock. There are no tall gantry cranes like those in large shipyards, or crane cranes like those in Binjiang Port’s cargo terminals. There are not even a few houses, and the surroundings are empty. It was barren.

In the major water fire accidents that occurred in the past ten years, almost all firefighters died.

"Just stay here, you can't get on the boat now, and you can't leave people here."

I saw six huge culverts on both sides of the "threshold" of the dock began to pour river water into the dock, and the speed became smaller and larger at a speed visible to the naked eye, and the flow rate changed from slow to fast.

The fire broke out in [-], but until today, many crew members of the Maritime Bureau believe that the passenger ship would not have sunk if it hadn't been for the help of the fire brigade on shore.

"Can't leave people?"

The leaders were all gone, and Guo Weitao, who was in charge of security, didn't have the same scruples as before. He went up to meet him and asked, "Yuju, it's cold outside. Why don't you invite some engineers, Boss Wang, and Boss Wu to 001? There is an air conditioner in 001."

The Fish Bureau said it would take three and a half hours to fill the dock with water.

Fish Bureau also talked about a very controversial case.

Two firefighters were killed and many more were injured during the fight.

Wait for the water level and water pressure in the dock to balance with the water level and pressure outside the dock, and then open the water pump in the pontoon type dock door to discharge the ballast water.

In addition to the potential for explosions, firefighting systems on larger ships can also overwhelm firefighters because of the carbon dioxide firefighting systems on board.If you don’t understand which valve you accidentally touch, or the carbon dioxide gas tank in the cabin leaks due to a fire, firefighters who don’t have oxygen masks or the replacement oxygen masks are of poor quality will suffocate to death due to lack of oxygen.

Moreover, fire fighting on water is completely different from fire fighting on shore. It is not that high-pressure water cannons are turned on to spray water wherever there is a fire.

A lot of concrete was saved, a lot of steel bars were saved, and conditions were created to ensure the quality of the dock and shorten the construction period, and it can provide certain experience for the design of our country's future docks and locks..."

The so-called dock gate is not a gate, but a huge steel floating tank, or a ship that can be flooded and sunk!
This floating box type dock door has three decks, below the lower deck is a fixed ballast tank, above is a water pump motor cabin, and on the side of the water pump motor cabin is a water tank.Above the middle deck is the overflow cabin, and there are two ladders on both sides of the overflow cabin. The two sides of the two ladders are also overflow cabins, and the top is the pedestrian passage.

When the dock needs to be drained, the [-]-ton dock gate is dragged by tugboats, flooded and sunk to the side facing the river, and the east and west ends are close to the "door frame" of the dock and the "threshold" under the dock .

When it sinks to the designated position and is reinforced, turn on several super-power pumps in the buoyant dock door to drain the water in the dock into the river until the water in the dock is emptied.

After interviewing the chief engineer of the Navigation Engineering Bureau, the reporter then interviewed the person in charge of the dock gate design and construction unit.

If the ship built in the dock is going out of the dock, several water injection valves on both sides of the "door frame" of the dock are opened to let the river water flow into the dock.

The passenger ship eventually capsized and sank to the bottom of the river, and was later salvaged by the largest salvage ship in China.

The wind was blowing, and the riverside was so cold, so the leaders naturally wouldn't wait here for so long. After visiting the floating box-style dock gate, they went back home one after another.

The immediate superior attaches great importance to safety. For example, a few days ago when the dam outside the pontoon-style dock gate was dismantled, he was worried that the pontoon-type dock gate and the ten-meter dock walls at both ends would not be able to withstand it, so he formulated several sets of measures similar to flood control and rescue Contingency plans, and guarded here for a day and a night, hardly sleep a wink.

The floating box type dock door rises when the tide rises, and it is towed away by a tugboat, and the ships that have completed construction or overhaul in the dock can enter the Yangtze River with the help of the tugboat.

If you don't participate in the training or listen to his lectures, you really don't know how dangerous water fire fighting is.

At this time, the azimuth tugboat hired from the Port Authority, which cost a lot of money, arrived.

He pays more attention to fire safety.

Another example is that if the engine room catches fire, you can't rush in with a water gun, otherwise no one will survive in the event of an explosion.

As for the few houses in the northwest corner, they were public toilets that were suddenly built for the completion ceremony of the main body, otherwise the leaders who attended the ceremony would have nowhere to go to relieve themselves.

Guo Weitao came to his senses and didn't dare to say anything more.

There are rubber pads on the dock door and the "door frame" of the dock, which can be tightly pressed together to stop the water.

The three engineers from COSCO did not leave, but watched the water injection together with Fish Bureau, Director Tang, Boss Wang, Boss Wu and the person in charge of the construction unit.

"This pontoon-type dock gate has a novel structure, which has the dual functions of water retaining and pump room. The top of the dock gate doubles as a pedestrian bridge. It is similar to the port gate in the hydraulic structure, but it is different. Water-stopping Well, it is easy to operate and maintain, and has certain promotional value..."

The enterprise fire brigade at the port was fully mobilized, and the fire brigade on the shore also went to hundreds of people and dozens of fire engines. However, due to the poor sealing of the cabin door, the fire in the engine room was not extinguished due to the release of carbon dioxide, so all water cannons and water cannons were used. Spray water into the cabin.

When an oil tanker or a ship transporting chemicals catches fire, it cannot be extinguished with water.

The so-called dock is a huge, deep, rectangular "pit".

The interlacing is like a mountain, and the professionalism of water fire fighting is very strong.

Therefore, at the symposium after the establishment of the Water Fire Fighting Association, the heads of various enterprises and institutions along the river and the heads of firefighters in several companies clearly stated that in the event of a water fire, laymen cannot command experts!
No matter the leader of the Changhang branch or the water branch, even if Director Chen of the Municipal Bureau came in person, he could not give orders to the firefighters.

At the meeting, a list of commanders for water fire fighting was drawn up. Fish Bureau was the first on the list of commanders. Fang Guoya, fire chief of Binjiang Port Enterprise, and Chen Zikun, acting director of Bailonggang Police Station of Changhang Branch, were also on the list. Ma Jintao, Captain of the Fifth Marine Police Squadron of the Water Sub-bureau, and others.

It is worth mentioning that the port supervision barge quickly changed back to the public security barge, to be precise, it turned back to "the first sentinel on the Yangtze River for thousands of miles"!
The Shuishang Sub-bureau and Linghai Public Security Bureau arranged special personnel to re-arrange. The inscriptions of the provincial leaders were hung in the command and dispatch room. The small meeting on the second floor almost became the honor room. Photo and text presentation.

Also in his twenties, he has done so many achievements and is so professional in water law enforcement and rescue, especially water firefighting. Guo Weitao admires his immediate boss from the bottom of his heart.
