The important role of mud-water separation system in shield construction

• Sep 29, 2021
• The mud-water separation system is an indispensable supporting facility in modern shield construction. Shield construction refers to the use of shield tunnel boring machines to excavate tunnels on railways, highways, subways, municipalities,...

The modern mud-water separation system pays more attention to environmental protection in design, and emphasizes environmental protection concepts in various aspects such as pulping, slurry mixing, separation equipment selection, and waste discharge. The KOSUN mechanical mud-water separation system is built based on the previous domestic and foreign construction experience and the high-standard rationalization suggestions put forward by customers. It takes scientific and technological innovation as the standard, and improves the current domestic low-level separation situation by increasing the configuration standard of the desilting device. The separation particle size reaches about 15 microns, which greatly reduces the amount of slurry preparation and reduces engineering costs.

 

 

The mud-water separation system mainly includes a vibrating screen device, a cyclone screen device and a filter press device, the vibrating screen device and the cyclone screen device are connected, the cyclone screen device and the filter press device are connected, and the connection mode is stacked connection Or connect with conveying equipment. The Shield Slurry Separation System of Kinway Energy can carry out different separation treatments according to different particle sizes, make full use of the beneficial particles in the excavated soil, improve the self-making capacity of the system, and effectively realize the separation of the mud and water in the shield tunneling, and the separation The latter water is re-injected into the mud water system for circulation. The equipment can be flexibly adjusted according to different terrain conditions. The convenient construction operation reduces the trouble of large area occupation of the mud water separation system and avoids mud pollution to the environment.
