Description

technical field

[0001] The invention relates to a method for receiving silt and fine sand layers of a small-section mud-water shield. Background technique

[0002] With the continuous deepening of urban rail transit construction, the application of shield tunneling technology in the field of underground engineering is becoming more and more extensive. At the same time, the underground pipe network and existing tunnels are becoming more and more dense, and the environmental and geological conditions faced by shield tunneling construction are also more complex. , the difficulty and risk of shield tunneling construction are increasing. The risk prevention and technical management of tunnels and complex underground engineering construction projects in China have made great progress in both theoretical research and practical application.

[0003] Shield entrance and exit holes are the key process of shield tunnel construction. The quality of the construction technology in this p...
