There are a variety of problems encountered in tunnel construction lining trolley. When we encounter problems and then solve them, it will be more troublesome. Therefore, we have sorted out some common problems and solutions of tunnel construction lining trolley. You can learn in advance. Now, if we really encounter these problems during operation, it […]
Tunnel lining is a statically indeterminate supporting structure, the main building of the tunnel, simply the inner lining of the tunnel. Its function is to prevent the rock around the tunnel from deforming or collapsing, a permanent support structure built with reinforced concrete and other materials along the tunnel. Lining technology is often used in […]
In recent years, lining trolleys have been used more and more widely in the construction of railways and highways. The relevant Ministry of Construction has also paid more and more attention to the quality of tunnel lining, and required the design, production and use of lining trolleys. Also getting higher and higher. However, due to […]
In the process of constructing the secondary lining of the tunnel, the tunnel lining trolley is a kind of special tunnel lining equipment that must be used. This is to ensure the safety of use after the tunnel is completed. The tunnel lining trolley is very important in the tunnel construction. After a lot of […]
Broadly speaking, the artificial support structure can be collectively referred to as lining, which can be divided into primary support and secondary support (secondary lining). Tunnel lining materials should first have sufficient strength, durability, impermeability, corrosion resistance and frost resistance. In addition, from an economic point of view, it should also meet the requirements of […]
Tunnel engineering has heavy construction tasks, large engineering volume, tight construction period, high investment, and strong seasonality. For tunnel construction machinery and equipment that operates in the field all year round, mandatory maintenance of equipment is particularly necessary. According to the data, 6% of the major failures of construction machinery are caused by mechanical operation […]
Tunnel construction is a difficult point in road and bridge construction. It has a complicated construction process and is different from other projects. It has the characteristics of concealment. If the survey and design estimates are insufficient or some precautions are not done during the construction, the safety of the tunnel may be affected and […]
As we all know, the construction of tunnels is relatively complicated and involves many difficult technologies, which brings great difficulties to highway construction. For this reason, it is necessary to strengthen technical research, improve the control level of tunnel quality management, and improve the overall quality of highways. Construction characteristics of highway tunnels During highway […]
In recent years, due to the acceleration of the internationalization process, the transportation industry has developed rapidly. Road construction is not only related to people’s livelihood, but also an important pillar to promote national economic growth. In order to promote regional economic development, many regions have overcome geographical restrictions to build highways, and tunnel engineering […]
Tunnel invert construction has always been an important factor affecting construction progress and quality control. In order to reduce the interference of invert construction on ballast vehicles and achieve the goal of accelerating construction progress, our company has developed a new automatic control hydraulic invert trestle. The automatic invert trestle has the following advantages: 1. […]
