Cable tunnel shield -- the overall solution of medium and small shield construction

Social urbanization has become a trend, and the continuous development of urbanization is bound to put forward higher requirements for the construction of public infrastructure on which the city depends for its existence and normal operation. As far as urban power grid is concerned, which is an important part of modern urban public infrastructure, the main problem we are facing is how to properly solve the contradiction between the rapid growth of power load and the increasing shortage of power supply point and power channel resources, the living space of people's green environmental protection and the requirements of urban environment. It is undoubtedly an effective solution to transmit power in the form of cable in the city There is no solution. At the same time, the tunneling and networking of urban power grid, which is accompanied by the power transmission cable, will become the characteristics and development direction of urban power grid in modern society, especially the super large international urban power grid.

China International Power Group cable tunnel shield method can provide overall construction solutions for different types of pipe network, with its own shield machine, providing professional and intelligent shield machine, segment and shield construction, etc., which plays an obvious role in improving urban living environment and shielding electromagnetic radiation of lines.

Typical application case: Guangzhou Yongfu Road Power Tunnel : it has been connected, Φ 3000mm, which has solved the problems that China Southern Power Grid has not been able to solve in 14 years; it is the first time in China to continuously make two 80m three-dimensional small turns; it is the first time in China to adopt push shield construction method; it is the first time in China to adopt double line approach construction with spacing of 2000mm; it is the first time in China to adopt mud concentration construction method; it is the first time in China to adopt vacuum mud discharge construction method; it is the first time in China to actually start shield separately; there are only 7 launching wells 000X7000。
