Seen the movie "Cool Mouse Adventures" who, in addition to never forget that a few small mice, the dense spider web on the London underground sewer system must also impressive. In this ancient city, the sewer is not the birth of a smooth start.

However, serious pollution in London 150 years ago, garbage everywhere, the city is full of feces breath, stink to high heaven. The whole of the Thames in the fermentation, the liquid flowing brown.

    The end of 1849 cholera epidemic, the number of cholera deaths in London more than 14,000 people, but the cause of cholera is still not clear. London at the time, the cemetery is always inadequate, and in some places, the dead corpse on the streets can only be exposed. In order to avoid body odor, was popular with Londoners wrapped the bodies to cover up the smell of onions.

    In 1853, cholera comeback. An infectious disease doctors John - History of the onset of labor cases one by one on the map marked in London and eventually concluded that cholera is caused by the water.

    Therefore, some people worry that the hollowing out of the London Underground would collapse. To solve this problem, engineering a new type of specially developed high-strength cement. To ensure the quality of cement, Base Jie invented a testing method, a modern pioneer in quality inspection of various commodities. With this new high-strength cement, creating a total of 300 000 000 8 10 million concrete blocks to form a solid sewer.

    Many times during the construction accident, such as digging of bad gas pipeline, and the subway opened up, landslides and so on. However, because of Base Jie strict management measures, the entire construction process, due to the number of deaths caused by the accident of not more than 10 people.

    1865, project was finally completed. Works longer than the actual design length of 2,000 km. Completion of the year, London-wide

大概是这样，自己在修改就行了……
