preface

Since the founding of the People’s Republic of China, the construction of railway tunnels in China has made remarkable progress, and its number and total extension have ranked first in the world. From the “jam neck” to the people without me, people have my advantage, the construction of the tunnel has improved the travel time of vehicles, make people’s life more convenient, improve the living standard, and the biggest hero of the tunnel construction is the shield machine.

With the development of urban construction, innovation and technology are playing an increasingly important role. Innovative technologies and applications represented by GIS, BIM, artificial intelligence, big data and 5G are also providing technical support for urban and industrial construction. The development of engineering construction also takes scientific and technological innovation as the breakthrough point to form a new ecological circle of innovation, synergy and interaction. Today, HT for Web products of Hightopo will be used to construct a lightweight 3D visualization scene, the construction process of digital twin shield machine, and clearly and intuitively show the components of the equipment, dynamic operation effect, equipment splitting, assembly and construction process.

Interface introduction and effect preview

We used the 2D/3D engine independently developed by HT for Web to create the visualization of the construction process of the shield machine after setting up the lightweight scene, matching the data panel and animation driver:

 

The scene consists of the 3D shield machine in the center and the data panel at the bottom. The scene supports conventional rotation, translation and viewing Angle scaling. Some relevant information about the construction process of the shield machine is simulated through the data panel.

Combined with HT data visualization panel real-time monitoring, real-time display of the construction process of various data indicators. Intelligent analysis and collection of background data, truly reflect the real-time dynamics of each module, so that managers understand the situation of each plate, rapid maintenance management.

Realize the value of

Traditional construction often adopts BIM model, but BIM modeling model data is often too large and bloated and the modeling model is not beautiful enough. Through the case, we can feel that compared with the traditional way of project construction, HT three-dimensional display has a more flexible form of expression and intuitive and vivid effect. For enterprises, vivid demonstration animation can enable customers to understand the working principle and advantages of the product faster, and compared with ordinary industrial animation, the visual system on the Web display content is richer, more freedom, subsequent requirements change is more flexible, and the cost is lower.

The application of 3D visualization technology can not only improve the work efficiency of the construction site, but also monitor the progress of the project in real time. The project also broadens the application space and application value of the visual model:

I. Reducibility: Digital Twin breaks the traditional mode of integrating construction information through plane drawings, and simulates the construction site of shield tunneling machine, as well as the internal system and state information of shield tunneling machine through three-dimensional visualization technology.

II. Informationization: HT visualization improves the drawbacks of information storage in the design, construction, operation and maintenance stages of the traditional mode, enables the information integration from construction to operation and maintenance stages, and ensures the timeliness of data. Through timely information feedback, possible problems encountered in the construction stage can be analyzed and learned, thus reducing the maintenance cost.

3. Greening: Follow the concept of green development, replace traditional manual work with emerging technologies, and increase green industrial development. As shield tunneling machine is applied in more fields such as subway, electric power, telecommunications, underground tunnels, undersea tunnels, rock tunnels and so on, the requirements for shield tunneling machine technology are getting higher and higher. Therefore, new structures, new forms and new concepts of shield tunneling machine will be introduced continuously.

System analysis

The basic working principle of the shield machine is that a cylindrical steel assembly is pushed along the axis of the tunnel to excavate the soil. The shell of the cylinder assembly, the shield, acts as a temporary support for the excavated, unlined section of the tunnel, bearing the pressure of the surrounding soil and, in some cases, the underground water pressure and keeping it out. Excavation, drainage, lining and other operations are carried out under the cover of shields. Shield tunneling machine can be divided into four structures:

Shield shell

The shield shell is composed of cut ring, support ring, horizontal and vertical baffles and shell steel plate. At the beginning of the project construction, the shield machine is first installed to the designated position through excavation of foundation pit for debugging.

 

Propulsion system

The propulsion system of the shield machine is mainly composed of shield jacks and hydraulic equipment, which are distributed in a circular shape along the support ring. By applying pressure to the segment, the shield machine is pushed back to advance.

 

The unearthed system

After cutting the soil with the cutter, it is transported to the rear through the conveyer.

 

Assemble the system

The assembly system can be said to be the skeleton of the shield machine. Usually, factories will produce a series of ring-shaped segments according to the specifications of the shield machine, and then assemble them through the ring-type erector. The segments have also become the supporting elements of the tunnel to ensure the safety of the shield machine.

As one of the most important equipment in tunnel construction, shield machine plays an important role. The project construction must also enhance the independent ability, improve the competitive advantage of the industry, take the green intelligence as the core, improve the overall management and control integration level and the manufacturing level, to create an intelligent manufacturing industry.

conclusion

Under the continuous promotion of the strategy of scientific and technological power, more and more technical shortcomings of China have been filled, and a lot of cutting-edge domestic technologies have been born. China’s shield machine has become a name card representing its strength, and many countries even come to buy it. By combining the visualization of HT’s intelligent monitoring and control and management system, it can promote the wisdom and depth of the future green industrial construction, effectively solve the cost consumption of urban construction, improve the accuracy of environmental monitoring and safety monitoring, and improve the quality and efficiency of construction.
