With the passage of time, the news of the occupation of Dayuan by a certain force will continue to spread, and the communication between the people and the outside world will become more and more frequent - in 1628, some medium and large ships will inevitably come to Dayuan, and at this time, the Dayuan channel and the dredging project including the entire Taijiang River will become more and more urgent.

"How efficient is this ship? How long does it take to clear the waterway? Xia Xianze, who had been watching Haidilao for a long time, put down the telescope in his hand and began to ask questions.

"The grab doesn't have a lot of capacity, so it's not going to be very efficient." Yao Zhesheng, the designer of the dredger, came out to explain at this time.

Considering the counterweight of the metal boom and the bucket, the top-heavy wooden raft did not dare to use the large grab, so the amount of sediment excavated each time was only 0.6 cubic meters. Coupled with the rudimentary operating system and the difficulty of moving the wooden raft itself, it is certainly not very efficient.

Of course, when it comes to efficiency, compared with some frenzied island-building ships in later generations, this submarine fishing boat is naturally weak, but in the 17th century, the efficiency of this ship was the first in the world.

"If the main channel is dug to an average depth of two meters, it should take less than a month." At this time, Chen Dong of the Ministry of Infrastructure on the side opened his mouth and added.

The main channel in Chen Dong's mouth is actually the "South Waterway" where ships enter and exit on a daily basis. The "North Waterway", which is separated from the South Waterway by a small Changsha island, was almost connected to the North Line Island due to serious silting in the early years.

"If it's two meters, this kind of ship doesn't need to be transported anymore, right?" After listening to this, Xia Xianze pointed his finger at the Xing'anping, which was heading to the other side of the Taijiang River.

"No, the steeple-bottomed Fu boat under 800 materials can pass."

"It's still not enough, half a year, it will take half a year to thoroughly deepen and widen the waterway, and it is better to dig up the sandbar and connect the north and south waterways into one. It is necessary to prepare the channel according to the draft of gunboats of more than 1,000 tons. Xia Xianze made a final decision at this time.

The people next to him have no opinions, and it will take half a year to dredge the most important waterway first, which is the right thing, and as for other places in Taijiang, you can bear with it for the time being. After finishing speaking, Xia Xianze raised the telescope again: "Where has the sand gone?" ”

"Deer Ear Gate." Liu Zhe, who was wearing a blue Type 07 naval uniform, replied, Liu Zhe, who is currently the commander of the coastal garrison force.

Luermen is a waterway at the northern end of Ojima Island on the northern route. The waterway is so narrow that only small boats can pass through it, and the water is turbulent and steep, and it is often subject to change. Due to the tide, earthquakes, and the diversion of Zeng Wenxi on the other side of the Taijiang River, Luermen is often in siltation and diversion, and it is unpredictable.

Originally, in history, thirty-three years later, the fleet led by the national surname, under the leadership of He Bin, the translator of the inner ghost, took advantage of the astronomical tide to rush into the Taijiang River from Luermen and burst the chrysanthemums of the Dutch.

The crossing does not need such uncertainties, even if there is a blockade by artillery fire and radar irradiation: the army instinctively wants to control all kinds of management loopholes. So Liu Zhe asked the barge to transport all the sediment to Luermen and completely fill in the waterway.

Not only the waterway is landfilled, but many places on the northern line of Ojima will be submerged at high tide, and all these places will need to be landfilled and raised in the future.

In the army's plan, the top of the northern line of Tail Island and the southern end of Dayuan Island will be filled with sea sand produced by dredgers in the future to fill in a sand bank connecting the main island of Taiwan. In this way, not only will the two islands have direct access to the land, but they will also be easy to defend.

The closed defense scheme in the shape of "mouth" blocked the possibility of the fleet rushing into the Taijiang River from other places, and only the main channel set aside in the middle of the left could enter and exit. Of course, if someone uses a small boat to shuttle people back and forth, and intends to form a team to rush from the sand bank into the big island, then the philosophical question of how many people can be penetrated by a 12.7mm machine gun bullet can get the correct answer......

...... After listening to Liu Zhe's defense plan for the entire Taijiang Inland Sea, Xia Xianze glanced around and saw that no one raised objections, so he nodded and said that the plan was feasible. The next thing is to go back to their respective homes - Haidilao has passed the acceptance, the on-site meeting has also been opened, and more than 10 people have scattered as birds and beasts.

......

Most of the people went back to the merchant hall to work, but Professor Luo hurried to the dock after coming down from the fort: now he was in charge of the business activities in this part of the Ming people, so he had to go to receive the Xing'an Ping and the Lin brothers.

Professor Luo actually just came back from Madou Club a few days ago. In the days when he was in charge of Madou, Professor Luo Lading Laling, beating the elders, abducting children, robbing people's daughters, in short, doing all kinds of evil.

After returning to the senior office, the large office promoted Professor Luo to the newly established director of the port authority, and to be in charge of domestic trade specifically for Ming merchants, in view of the outstanding achievements of Professor Luo in providing many young students, students and women of childbearing age to the kiln district, Chihkan Primary School and the new district during his time in Madou.

When Professor Luo arrived at Chihkan Wharf on a small sampan, the Xing'an Ping had already entered the berth and anchored...... The Lin brothers were directing the unloading at the bow of the ship at the moment.

Until now, the brothers have not been able to wake up from the shock brought to them by the big man. The difference is that Lin Baoan is a little younger, and his attention is still focused on the fishing boat at the moment, standing at the bow of the boat and still looking back.

And Lin Baoquan is well-informed and steady, but what makes him more concerned at the moment is the Chihkan New District behind the wharf.

The east bank of the Taijiang River has now been planned. The Chihkan City/Chihkan District Government Affairs Grid, which is under construction, is located in the middle of the Taijiang River, facing the Dayuan Commercial Hall on the other side. Bounded by the Chikan square, there are several high-end sea-view residential blocks to the north, and further north to the corner of the Taijiang River, where the shipyard and the shipyard dormitory area are planned.

To the south of Chikan City is the wharf and storage area. The Xing'anping is parked in the newly built dock area in the lower right corner of the Taijiang River, where other planned wood-gas cold storage has already begun, and the storage block, including various large warehouses, will continue to the south.

As a high-end sea-view residential area with a priority after Chihkan Primary School, the first square has been completed: long red brick walls, beautiful black basalt paths, and tropical camphor wood huts, which look messy but are in fact just right to block the eyes of neighbors......

This is not a rigid staff dormitory, these huts for the crossers to live in, are the standard configuration of the seaside tourist area in later generations, with exquisite materials and complete equipment. The owner can not only sit on the verandah and watch the sea view and drink iced tea, but also eat kebabs at the back of the house, and the interest can also come to a hair with the girl in various dark corners, it can be said that the design is reasonable, the style is coquettish, and there is no formaldehyde...... There is a shortage of girls.

The girl is not far away - after the completion of the community, the fleet carrying a lot of raw and mature girls began to rush to the big man as soon as possible. Mature girls haven't seen their master for half a year, and the raw sister doesn't know who her master is. But it doesn't matter, the purchasing agent has already sent the selfie back to the big guy, so the old man knows who is who.
