Zhang Yushe Our reporter Wang Qian

Chairman-Liu

On March 28th, it was reported that from the second half of 20 1 1, a humble company in Changsha, Hunan Province suddenly welcomed the visits of nearly 20 groups of investigation teams, including the Quality Supervision Bureau of the Ministry of Transport, the Transportation Departments of Hunan and Shanxi provinces, the Quality Supervision Stations of Jiangsu and Henan provinces, the owners, supervisors and construction units of Guangdong, Yunnan and Hubei provinces. What triggered this round after round of research upsurge was the prestressed intelligent construction technology pioneered by this company.

In just two years, the output value of Hunan Lianzhi Bridge and Tunnel Technology Co., Ltd. (hereinafter referred to as "Lianzhi Bridge and Tunnel") has rapidly developed from less than 5 million yuan to several hundred million yuan, and the rapid development of Lianzhi Bridge and Tunnel has become a miracle in the transportation industry of Hunan Province. More importantly, as a start-up, it is a rare phenomenon in the development of small and medium-sized enterprises to develop an engineering system with domestic leading level and successfully promote it. What is the secret of its success with such a rapid development speed? The reporter interviewed Liu, the chairman of the company.

Seeing that some bridges did not reach the design life, they were "retired" in advance because the prestress did not meet the requirements. Liu's mood has not been calm for a long time. How to make the bridge meet the design standards, avoid the phenomenon of "retiring" in advance, and make the bridge in China safer? Liu led the team and Liang Xiaodong, general manager of Lianzhi Bridge and Tunnel, to develop an intelligent tensioning system for bridge prestress, which was successfully put into use. Because of its important role in bridge safety, the products were widely welcomed as soon as they came out.

Service and market expansion

When the reporter first met Liu, his wisdom, frankness, humor and friendliness left a deep impression on the reporter. Liu said that the company's rapid development first benefited from catching up with a good period. On the one hand, there are more and more testing institutions in China, and the competition pressure is increasing, but there is a lack of innovative consciousness and research results that can solve practical difficulties. In this context, Lianzhi Bridge and Tunnel has filled the market gap through scientific and technological innovation. On the other hand, the employees of the company are very young, with an average age of only 29 years old and full of vitality. In addition, 30 years of working experience in the transportation industry has enabled him to accumulate a wealth of knowledge, and his frank attitude has been affirmed by everyone, and his contacts are also very wide. The most important thing is the core cultural concept of the enterprise, that is, service consciousness, which regards rights as responsibility, serves the enterprise and serves the people.

Service awareness has played a vital role in the development of Lianzhi Bridge and Tunnel, which has made the company widely recognized by all sectors of society in a short time, strengthened the cohesion and centripetal force of employees, and reserved strength and space for the company's subsequent development. Want to gain a foothold in the market depends on two factors, one is quality and the other is service. On the basis of ensuring the quality, Lianzhi Bridge and Tunnel strengthens the service consciousness, develops the market and stands firm in the market.

Innovate to solve difficult problems

Like people, bridge structure has its own life cycle, that is, the service life of the bridge. However, many bridges are damaged and collapsed for various reasons far from reaching the designed service life, causing huge economic losses and even life-threatening, leaving endless regrets.

Lianzhi Bridge and Tunnel was originally a small highway engineering test and detection unit. During the inspection, the company found that the frequent occurrence of "short-lived" bridges was due to problems in the two key processes of tensioning and grouting during the prestressed construction, and no effective prestressed system was established. As a result, the company set up a research and development department to attract professionals and develop new technologies to solve problems.

After the bridge prestress intelligent tensioning system independently developed by Lianzhi Bridge and Tunnel was successfully put into production, it began to be popularized on 20 1 1. So far, more than 30 expressways under construction in Hunan Province have fully used this system, and Hubei, Jiangxi, Hebei, Henan, Guizhou, Fujian, Gansu, Xinjiang and other provinces have also begun to introduce this technology to ensure the quality of bridge construction.

Following the successful research and development of intelligent prestressed tensioning system, they led the R&D team of the company to overcome another difficulty of prestressed technology, successfully developed a long-period intelligent grouting system, and made a subversive innovation in traditional grouting from concept to technology, forming a set of intelligent prestressed tensioning grouting technology, which completely solved the problem that has been bothering builders in bridge construction.

Intelligence promotes standardization

With the continuous occurrence of bridge accidents, people pay more and more attention to the safety and quality of bridges, and the prestressed intelligent tensioning system independently developed by Lianzhi Bridge and Tunnel fundamentally solves the hidden dangers of safety and quality.

The traditional prestressed tensioning equipment has some shortcomings, such as the accuracy can not be guaranteed, the effective prestress can not meet the design requirements, the technical data can not be controlled manually, and it is time-consuming and laborious. The intelligent prestress tensiometer developed by Lianzhi Bridge and Tunnel is controlled by computer from equipment installation, data input, tensioning implementation and result generation. It has high intelligence, high speed and simple operation, which greatly improves the accuracy and construction quality of bridge prestress and completely eliminates the influence of artificial tensioning on the construction quality of bridge prestress.

Large-circulation intelligent grouting can completely exhaust the air in the pipeline and bring out the residual impurities in the channel, accurately adjust and maintain the grouting pressure, monitor the flow in real time, automatically monitor the slurry quantity in the pipeline, and inject two holes at a time to improve the work efficiency.

"The intelligent tensioning system controls the whole process through computer programs. Only two people need to work in the tensioning process, one is to operate the computer, and the other is to observe the tensioning progress at the other end. Owners, supervisors, construction and testing units can break through geographical restrictions on the same Internet platform, control the construction situation in time, and realize real-time tracking, intelligent control and timely error correction. " Liu said:

The reporter then went to the production base and saw that the upper and lower holes at one end of the beam were connected with two pipes, and the two holes at the other end of the beam were also connected with pipes, forming a closed circulation loop. The whole grouting process is completed automatically by instruments, which excludes the influence of human factors. The grouting site is clean, environmentally friendly and economical, and the slurry is not wasted at all.

The real-time data on the laptop screen near the operation console caught the reporter's attention. These data are transmitted to the computer control terminal through the wireless sensor, and the construction personnel can know the data such as pressure, flow rate and water-binder ratio at the inlet and outlet of the pipeline at any time.

Culture shapes brand.

Excellent products can not be separated from the high standards required by production enterprises, and the quality requirements of Lianzhi Bridge and Tunnel meet the needs of the construction environment.

Regarding the future market space of Lianzhi Bridge and Tunnel, Liu confidently said: "Last year, more than 260 people from1kloc-0/province (city) visited and studied in our company. This year, we received 8 teams from Guangdong, Jiangsu, Fujian, Tianjin, Ningbo and other places, and strived to promote them nationwide. "

"Take testing and testing as the traditional industry, take technology research and development as the core, pay attention to the research and development of series products, expand the market, and achieve' both hands must be grasped and both hands must be hard'." When talking about the future development direction of the company, Liu described the grand blueprint like this.

In the future, Lianzhi Bridge and Tunnel will focus on brand building and talent building, establish a corporate culture with quality service as the core, strengthen enterprise system construction, strengthen talent training and strengthen the implementation of execution. Using modern technology to make bridges in China safer.

Liang Xiaodong: Read a good book (1)

Source: General Manager of the Company Author: Liang Xiaodong Release time: 2009- 10-28 hits: 8 14.

Reading a good book benefits a lot. In the meantime, I suggest and encourage you to use your precious time to read a good book that is generally considered valuable and savor its ups and downs. With two brand-new communication platforms, company briefing and website, I will gradually share some of my reading experiences with you to encourage you. From the first sentence of Cher, the beginning of The Analects of Confucius.

Confucius said, "It's better to keep pace with the times, isn't it? Is it not delightful to have friends coming from distant quarters? Ignorance and dissatisfaction are not gentlemen? "

General idea: Confucius said, "isn't it pleasant to learn knowledge and truth, and to study continuously every day, and to improve your knowledge and cultivation day by day?" Aren't you happy that my good friend came to meet me in Wan Li not far away? Even if others don't understand, don't understand, and don't understand themselves, they can not be angry, don't be angry, and they can face it calmly. Isn't it also a gentleman's move? "

This is a well-known masterpiece, and everyone must have a general understanding of its meaning, which has been gradually realized since childhood or youth. With the passage of time and repeated chanting, I can understand the profound significance of these three rhetorical questions more and more.

First, "always study, don't you?"

Study hard and make progress every day. I believe everyone knows the reason. Maybe I took learning as a task when I was a child. There is a joke that "there are seven people in the family and six people are farming, and the task of reading is the hardest." Nowadays, children, reading has surpassed the task and has risen to an arduous and glorious mission. The heavy schoolbag carries too many expectations, which makes the tender shoulders overwhelmed. In our generation, reading has almost become a means of making a living, because of endless entrance examinations, textual research, evaluation of professional titles and examinations. What time and mood do you have to savor a good book and swim in the sea of books with a pleasant mood?

In fact, no matter how high your position is or how busy your work is, you always have the conditions and time to study. In addition to completing task-based reading, in fact, we urgently need to read some good books to recharge our batteries, deliver oxygen and avoid spiritual desolation. In recent years, we have taken many detours, experienced many lessons, and caused great losses and wasted a lot of time. Why? Read more books and understand the truth. In fact, it is entirely because my knowledge is too shallow, my understanding of the truth of dealing with people is still superficial, and I have not learned enough. So Fang sighed, "Standing at thirty, not confused at forty." The testing business we are engaged in is a very demanding business. On the one hand, it needs high professional knowledge, on the other hand, it also needs high personal accomplishment. So I suggest you read two more books: one is a professional knowledge book, and our knowledge needs to be accumulated day by day to improve our experimental detection level; Another book is about life and morality. Only by absorbing the essence of traditional culture and constantly understanding the truth of being a man and doing things can we have good professional ethics and integrity and avoid bringing losses or even disasters to ourselves.

I have to admire the insights of the ancients. Learning is always a major event in life. Learning is endless, learning from time to time is beneficial, and the essence of learning is enjoyment.

2. Isn't it a pleasure to have friends coming from afar?

How happy it is to have like-minded friends together. One can't live without friends. If learning is like the food we need for three meals, then friends are around us like air, so that we can live without feeling lonely. When a friend came, the sincere joy was beyond words. This pure emotion reflects a person's sincerity and his cooperative attitude. We need to exchange knowledge and technology so that we can make rapid progress in a short time. Sharing is also a psychological need of people, and sharing is happy. People eat incense around the table, as the old people often say.

The test involves construction, supervision, owner, government supervision and a large number of related personnel. In our hearts, they should all be our friends. Whether we get praise or criticism from them, we should regard them as communication between friends. They are good to us, and we should be good to our friends. Honesty, sincerity and making friends are extremely happy things!

Simple emotion makes me win friends, which is the source of happiness.

Third, people don't know and don't care, aren't they gentlemen?

If others can't master a certain knowledge and technology and have problems in their work, we should try our best to help him, improve others and ourselves. Especially as company leaders, middle-level management cadres and project leaders, we must be strict with ourselves at this point. With less criticism and more help and care, you can win the hearts of team members, and you can become a qualified cadre and a mainstay of the company.

Sometimes, do you get angry because your talents can't be discovered or your good wishes are misinterpreted? If you answer "no", you will become Confucius, but there is only one Confucius. The most reasonable answer is "yes". But don't be angry for more than ten seconds, then you are still a gentleman. Learn to control your emotions and adjust your mentality in a short time. Your merits, achievements and contributions can't escape the eyes of the masses and leaders in the end. Gold always shines. Don't feel sorry for yourself because one person can't see it for a while, ignoring that your light is being appreciated by 99 other people. Understand and appreciate everyone around you, no matter how he treats you temporarily.

Good for evil, tolerance is great.

Reading a good book benefits a lot. A passage in Learn to Learn, just three sentences, can make people realize so many truths. Knowledge, technology and literacy are also constantly drawn from this good book. Thereby making life more colorful. Gentlemen * * * encourage!
