In July 21st, the first tunnel intelligent grouting equipment in China was successfully developed in the railway construction heavy industry. The equipment has six functions such as automatic planning, automatic grouting, automatic grouting, automatic measurement, automatic cleaning and data interaction. The equipment has high intelligence, high work efficiency and good construction quality in the construction. Potential.
For a long time, there is a lack of professional grouting equipment in the field of tunnel construction in our country. There is no mature grouting technology, and the supervision of grouting process is not in place. There is a phenomenon of "blind injection" in the tunnel construction. The grouting effect is not obvious, and the effect of grouting is not obvious. The phenomenon of roof and collapse often occurs when the face is excavated. Self stabilizing ability directly affects construction period and operation safety.
"And the intelligent grouting equipment is the star of the soft surrounding rock and water gushing water rich tunnel. Through the high-pressure grouting pump, the slurry is injected into the rock layer to complete the water stop and reinforcement of the tunnel surrounding rock, so that the tunnel is more solid and let the water stay outside the tunnel." Zou Liyong, director of the Institute of tunnel equipment Research Institute of the special equipment Research Institute of iron construction heavy industry, introduced that the intelligent grouting equipment has been used in many projects abroad and has achieved good practical results.
It is understood that intelligent grouting equipment is a kind of equipment of tunnel intelligent equipment system being built by railway construction heavy industry. The company has developed the tunnel intelligent equipment since 2012. The autonomous development of the tunnel intelligent equipment has been successfully applied in the tunnel engineering, such as Zheng Wangao iron, jade mill railway, national defense engineering and so on.
The grouting equipment developed by the iron construction heavy industry has the intelligent characteristics of "automation, visualization and information". The equipment not only has the self perception, self decision and self executing functions of the grouting process, but also makes the grouting process, the grouting result visualized, and also realizes the data auto acquisition, storage, transmission, analysis and interaction. Big data information management.
Reporters at the scene saw that the intelligent grouting equipment was more than 30 meters long, consisting of three parts, namely, the chassis, powder unit and grouting unit. In the demonstration test, according to the geological data of the intelligent rock drilling platform, the grouting plan is completed automatically. The grouting is automatically made according to the proportioning. The grouting is automatically injected according to the planning data. The grouting log is automatically measured and the grouting can be automatically cleaned after the grouting is completed.
With the deep development of the western development in China, the number of bad geological tunnel projects, such as soft rock and karst development, is increasing. The development of intelligent grouting equipment provides new support for improving the efficiency of tunnel construction, ensuring the safety of the construction and protecting the natural environment.
"In fact, the intelligent grouting equipment is like a general practitioner. It can prescribe different prescriptions for different geological conditions, automatically match the grouting parameters based on large geological data, control the grouting process accurately, realize the grouting data, and the grouting quality is controllable." Zou Liyong told reporters that the intelligent grouting equipment can produce 65 liters of liquid every minute, and has reached the advanced level of international similar products.
Liu Feixiang, the party secretary and chairman of the Party committee of the construction of railway construction, and the leader of the technology leader of the tunnel intelligent equipment system revealed that at present, iron construction heavy industry is building the intelligent equipment system of the whole process tunnel, which covers the series of processes such as advanced operation, excavation, ballast, initial support, inverted arch and side wall, two lining, groove application and inspection maintenance. The tunnel construction equipment will eventually achieve artificial intelligence, and promote the green intelligent construction of tunnel with no lights, no lights and oxygen free operation.
