Yan Mian (1774-1840), who was born in Renhe, Zhejiang Province, was an official of the Qing Dynasty. Jiaqingzhong, into the money to pass judgment, hair Nanhe, tired of Xuzhou Road, Ding Mu worry.

brief introduction

In the first year of Daoguang, he was granted the North Road of the South River. Looking for life, the governor of Hedong river course was appointed by the top of Sanpin. Sanxun Anlan was the real teaching. Wenshui was blocked when it was overflowing. It was said: "the most important opportunity for the North Canal Road is to store wendiwei. The Wenshui layer must be raised, and then the wendiwei water can be stored. Please increase the investment of linqingkou brick gate. " Follow it. In the early days, Li Shixu used gravel to control the Nanhe river. He asked Chidong River to follow his example. According to his theory, he asked him to build a dam on the North Bank of Maying and cast gravel in imitation of the Nanhe river. It was estimated that the work would cost 100000 liang of silver. Cheng Hanzhang, the political envoy, and Yao Zutong, the governor, successively said that it was inconvenient. However, since Maying had silted up, the water potential in front of the dam had slowed down. Therefore, we still need to cast the gravel at the end of the dam.

Four years

Gaojiayan burst in Nanhe River, and it was transferred to Jiangnan river. In the fifth year, he cooperated with Wen Fu and Wang Tingzhen: "storing the enemy Yellow River in Qing Dynasty is the first key to river affairs. When the dike breaks, the clear water will be drained away, and the heavy transportation will be temporary, so there is no floating transportation. According to the law of the ancients, we should borrow Huang Jiyun. The canal is narrow and the Yellow current is turbulent. If it is too small, it will not be able to accommodate it. If it is too small, it will be shallow. It is suggested that three dams should be built outside the Yuhuang dam to restrain the flow of the Yellow River. In addition, a fiber channel was built to tie water and fiber. In the long rivers of Li and Yang, dredging and silting were carried out to help cultivate the dyke body, store materials and materials, build dams at any time, and force sliding and brushing siltation. If the Yuhuang dam is not opened, the weir will be raised to lead the water into the river; if it is opened, the water will be strictly blocked and the water will flow into the lake. When it comes to repairing the lake embankment, it is necessary to take advantage of the cold weather and dry water, so it is easy to get soil. It is planned to collect materials nearby and build ten storeys high before the flood season to prepare the lake water for growing. It will cost three million dollars. " He also discussed the issue of the Shangnan River in reply to the Minister Zhu Shiyan. The main idea is: "to demolish and repair the Gaojia weir dam, first build the dam for work, and then throw gravel outside the stone dike to make a flat slope, so that it will never collapse. In addition, a fascine dam was built on the Salt River in the Wangjiaba dam, and a stone rolling dam was built at the old dam sites of Renyi and Lixi to prevent abnormal inflation. " And if it is discussed. So I will join sun Yuting and others in the heavy transport. After the Yuhuang dam was put into operation in May, the river was still shallow and the water vessels could not pass through. The nearby dam was difficult to carry on the stripping and transportation. Yuting was reprimanded and he was also kept in his post. Qi Shan, the governor of the two rivers, said that he was afraid to leave without permission because of the economic situation. Qi Shan, the governor of the two rivers, ordered him to carry out the investigation and still ordered him to store enough water for the next year's plan of fighting against Huang Jiyun. He said: "in the past, the bottom of the Yellow River was deep, and when the lake water was collected to several feet, it could be poured out. The dike body was not very heavy. Now, the lake water must be stored up to two feet before it can be built and painted yellow. With 400 miles of vast lake water, relying on a single levee for protection, the westerly impact is bound to burst. It is proposed to imitate the method, and build a gravel flat slope outside the dike. Since the dike is solid, the lake water can be stored. " He also accompanied Qi Shan to play Chen: "to brush the Yellow River, the lake water must be collected to two Zhang. Last year, the lake was more than seven inches in length, causing the crash. It is difficult to store enough clear water, but the two methods of storing clear water and reducing yellow water are in parallel. Gravel dike, so storage clear; moved to Haikou, so reduce yellow The imperial edict is ready. "From Wangying to guanhekou, the Yellow River can be channeled into the sea. The beach outside the mouth of ChaGuan river is too high to turn. However, if the gravel is thrown on the flat slope, the benefit of clearing away and brushing the yellow will be gradually collected. It will cost more than 6 million yuan and should be handled annually. "

Six years

After the completion of the stonework in Honghu, we knew that the work was not solid enough to rely on. So we decided to take charge of the gravel work. We threw 300000 cubic meters of stone every year, and it was only eight years before it was completed. Xuanzong angrily denounced: "since he was transferred, he has nothing to do. The yuhuangba dam has not been opened up to now and has not been handled properly. If you want to build a guard in Donghe, you will have to lower your grade three to wear it. " He was the governor of Hedong river course. In the seventh year, he was awarded the title of second grade official. Taking the northwest of chaiba in Lanyang as an example, we have achieved good results by throwing gravel forward. In case of autumn flood, we are still heavy. Please widen the slope. Eight years later, please continue to throw down the gravel in the North Hall and Lanyi hall, and store the stone in the dangerous works of Zhonghe River and Xianghe river for protection. In the 11th year, zhong chang, his servant, was ordered to spot check Donghe stockade. Xianghe and Cao Kao stockade were loose and decayed, and they were not observed. They were demoted to three grades and kept in office. If you are sick, please open the vacancy.

Thirteen years

When he recovered, he went to Beijing to talk about Zhejiang seawall. In the fourteenth year, Zhao Shengkui and his servant Zhao Shengkui were ordered to go to the exploration site. Please take the time to repair the fascine to protect the root of the pond. Fifty thousand silver was allocated for the repair. There is no need to supervise the work. He begged to return with illness. In the 15th year, Wu Bangqing, the governor of Hedong River, impeached him to throw stones and received the red seal fee to transport and reduce the cost. Twenty years, death.
