The rock and soil layer below the original record of the ground surface has turned into a hard rock layer, and it is clearly separated from the coal shaft excavated by the coal mine under the former Municipal Bureau of Geology and Mineral Resources into two layers, and the rock layer is not a whole, but there are many coherent cavities.

According to the analysis of the drill out of the rock sample, the stone density is extremely high, the stone body is extremely hard, and the drill bits are worn and scrapped when taking stone samples, which makes the planning and design department involved in geological exploration very surprised, and immediately rolled out multi-point drilling work, and found that the ground is densely packed with boulder cavities, which can be extended in all directions.

After a round of heated discussions, the original subway theory remained popular, but because the current situation showed that the underground rock formation was too hard and the construction was too difficult, it was finally covered by the light rail theory.

Lao Lan, who was the director of the city's planning bureau at the time, was a die-hard supporter of the light rail theory, and he believed that following the whole country to get on the subway was not in line with the actual situation of the city.

He said that from the topography of our city, it is a basin trend, the underground is densely covered with the original abandoned coal mines, and there are many inferior coal mine resources that have not yet been mined.

On the basis of in-depth study of the latest geological data, Lao Lan put forward a jaw-dropping planning project proposal: we can make use of the underground coherent hole resources and abandoned coal mine tunnels to make a double-layer three-dimensional sewer project to fill the gap in China.

Unexpectedly, this suggestion reached the ears of a certain vice governor in charge of urban construction in the province, who had just been promoted from the main hall of the capital to serve as a vice provincial minister in this province, and was still a member of the standing committee of the provincial party committee, and had a relatively heavy voice in the province.

He has been engaged in urban construction management for a long time, and worked in Qingdao, Shandong Province in his early years, and is full of praise and admiration for the sewer project left by Lao De a hundred years ago.

In the following decades of his working life, he always wanted to find a city to do this kind of three-dimensional sewer project pilot, but the domestic system of liuguan has always made him unable to achieve his wish.

Now, in this medium-sized city that is very remote from the center, there are people who have such courage to dare to make such a suggestion, and he can't help but appreciate and support it.

Although the three-dimensional sewer project is only on the agenda, it is still necessary to consider the urban light rail project first, after all, the funds are limited, and the water and sewer project, which does not show political achievements and takes too long to take too long projects, still has a lot of resistance from planning to implementation, but it does not prevent the vice governor of the Standing Committee from appreciating and promoting Lan Xinbo.

Therefore, under the strength of this duke, there are already two Lao Lan, who is in the process and has enough qualifications for a total of three years, and he ascended to the high position of the deputy department and the deputy mayor in charge of urban construction who did not have much hope in his official career.

In fact, the original intention of Lao Lan's three-dimensional sewer project was made by Lao Mai intentionally or unintentionally.

In order to prevent collapse, he exerted his peerless soil system skills to tamp all the rock and soil layers above the abandoned coal mine to make it a stone formation with a strength comparable to that of a 10,000-year-old stubborn stone.

At that time, Lao Mai had a flash of inspiration, and he also had the same idea as Lao Lan, seeing that the roads in the city were all year round, digging roads every day in order to bury water pipes and lay cables, and the whole city was like a mole's nest, with a pile in the east and a pile in the west full of temporary road repair projects.

At that time, he thought to himself that he could make a sewer mold first, and in the future, Lao Lan would have the opportunity to come up, so he would let him do this, not only to reap the merits and achievements, but also to benefit the country and the people.

For this matter, Lao Mai really took a lot of effort at the beginning, and also made full use of the abandoned air-raid shelter resources during the original "deep digging" period, when he was in the beginning of Jindan, his strength increased greatly, and the excitement in his heart was indescribable, and he happily became the founder of the foundation of the city's sewer project.

For a time, the city's underground ravines are vertical and horizontal, the stone caves are dense, and the tunnel-like caves extend in all directions, and the soft soil is filled in the holes one by one, as long as the soil is removed, it is a huge all-natural underground drainage system channel.

Lao Mai later learned that there was a motion for this project, and under the impetus of Lao Lan, he was starting to do the preliminary work of the project.

Because Lao Lan came to Lao Mai for a difficult matter before the change of the municipal government, he said this by the way, and Lao Mai smiled bitterly in his heart, he seemed to be quite naïve at first, but he never thought that to this day, it is really Lao Lan to promote this matter.

Lao Lan's intention was not to do the sewer project, but to ask for help financially, because Lao Mai had agreed to it.

One day, a section chief of a certain department in the Organization Department of the Provincial Party Committee called Lao Lan, saying that the provincial leaders recommended and recommended the procedures, and if they wanted to stay in the city and be elected, the price would be 200,000 yuan, and said that this was the rule in the provincial organization department.

Lao Mai scolded with a smile when he heard this: "What's the matter, the market price is long, and the price of this official is also long, didn't you say that it was only 100,000 a few years ago?"

Lao Lan scratched his head and said: "It can be regarded as keeping pace with the times, but I don't want to pay for it, and I have to get the position of deputy mayor of this city, otherwise, I will go to other small cities, and I have to do the three-dimensional sewer project, I can no longer stand digging roads, burying pipes, and laying lines in the city every day." ”

He then said very seriously: "Lao Mai, you said you would help me, I listened to your words, in the past few years, it has really been a breeze on both sleeves and a body of alcohol, except for salary, I dare not touch any other money, oh, this is my salary card, you call 200,000 yuan," he took out a bank card from his wallet and put it on the coffee table and pushed it towards Lao Mai.

They were sitting in the bridge building of the secular headquarters of the Jinshi Group, in a suite reserved for Lao Lan, drinking tea and talking cordially.

Lao Mai smiled and pushed the bank card back, and said: "There is no problem with the money, just don't punch in, it will leave traces that have not been checked, you leave a channel to send money down, I will let people send it there in your name, and you touch the cash by yourself," On the eve of his early retirement, he was told by the villain because he was still ignorant about speculating in stocks after being promoted to the deputy department, and he still remembers it vividly.

Lao Lan was surprised: "Find someone to help you deliver, there won't be a problem, right?"

"Don't worry, the person sent must be someone close to me," Lao Mai patted Lao Lan on the shoulder and comforted, "In case something goes wrong, I will do the murder and burial, and it will definitely not involve your brother." ”

At this point, he can still have full assurance that the world's masters are not vegetarians.

"Old classmate, thank you for your kindness, I'll tell you the details. ”

Lao Lan gave Lao Mai all the time, place, characters and joint codes, and left in a hurry with his bag, and Lao Mai handed over the matter to a capable outer disciple under Ah Guang to handle it, and he believed that this matter would be done properly.

In August of that year, the end of the municipal government's re-election work, Lao Lan was successfully elected as the deputy mayor, and at the first government executive meeting, it was determined that he was in charge of urban construction and other work, and also began to vigorously promote the work of the urban double-layer three-dimensional sewer project.

After seeking investment from the central government, loans from the China Development Bank and financial appropriations from the city, the project started on a small scale in the dry season of 2008 and was listed as a practical project for the private sector in 2009.

When there was a problem in the early stage of the project, Lao Mai gave him a trick, which was just two words: "dredging".

It means that he uses small machinery to dig mud like coal miners in the past, without touching rocks, and he also introduces the feng shui Taoist Xuankong Taoist who he saw at Boss Luo's banquet in the past to Lao Lan as a private feng shui consultant, secretly as his own mouthpiece.

In less than a few months, the original one-year construction time was greatly reduced, and more than 100,000 square meters of excavation area were displayed to the world through television and newspapers.

When the main leaders of the city wore engineering hats and led a large group of relevant department personnel to appear at the construction site, there was a feeling of being in a foreign three-dimensional sewer project.

For a long time, there have been many mixed opinions about the launch of the three-dimensional sewer project.

The word "praise" mainly comes from ordinary cadres and ordinary citizens of the working family, and the word "depreciation" mainly comes from the mysterious leaders and departments concerned.

After all, in such a large basin city underground, excavate a criss-cross three-dimensional sewer system, the difficulty of construction and time is too great, just like the domestic to do any major things, to pilot to give people confidence and experience, now the results of the small range of construction, so that the main leaders of the city are amazed, but also give him full confidence.

Wearing an orange engineering hat, he asked Lao Lan Dao beside him as he walked: "Vice Mayor Lan, do you confirm that you can complete this project on time, quality and quantity according to the planned construction period, within the two terms of office of the municipal party committee and the government for ten years?"

Based on the astonishing results of the small-scale construction and the promise given by the chief of the Xuankong Dao Detective, Lao Lan said with confidence: "If the construction in other areas is this kind of mud and stone structure, instead of two five-year terms, one term is about the same, we can dig out the tunnel in two years and carry out the construction of internal buildings in two years." ”

The main leaders of the city listened to the eyes of the bright eyes, this is a real political achievement, a practical project for the people that can fill the gap in the country, if it can be successfully completed in his first term of office, it is more than enough to send him to the Standing Committee of the Provincial Party Committee.

The director of the city's urban and rural planning, who walked on the other side of him, added: "According to the results of geological exploration at various fixed points, the underground geotechnical structure in other areas is similar to this one, and the situation and estimated time reported by Vice Mayor Lan just now are based on facts." ”
