Slurry Balance Shield,Compound Earth Pressure Bala

ZTE series compound earth press balance shield, applying to clay,sandy clay,grit and discontinuous hard rock, is the tunnel construction equipment with independent intellectual property rights and is also one of the 16 major technical equipments of the Sate Council,which is developed by our own company through introduction and absorption of foreign advanced technology. The cutterhead rotates and cuts the earth, which is then sent to sealed earth chamber, and the screw conveyor continuously transported the earth when the pressure in sealed earth chamber and earth pressure of excavation face achieve a balance. Earth pressure balance shield can realize the one-time forming of tunnel full section. Using computer control, closed-circuit television surveillance and industrial operation, earth press balance shield is a complete equipment of tunnel construction, integrating the machine, electricity, hydraulic, sense and information technology, and is widely applied in the tunnel construction, such as water conservancy, electrical power, traffic and underground utilities. Main features of ZTE series compound earth press balance shield 1. Speed: Industrial construction, which is an integration of excavation, supporting, mucking and transportation. Continuous excavation. Fast excavation. Higher efficiency. 2. Quality: Reliable Quality with one-time forming of cutting earth mass, mucking, segment installation and synchro injection 3. Efficiency: Fast construction speed, short construction period, small amount of overexcavation, lower labor intensity, lower material cost. 4. Safety: working conditions is improved, effective protection guarantees the tunnel construction safety, and accidents are greatly reduced. 5. Environmental protection: small pollution on the construction site, good environmental and ecological protection. 6. A high degree of automation and informatization, using computer control, sensors, laser guidance, measuring, advance geological exploration, communication technology, construction data acquisition, posture management, real-time remote transmission of construction data, informatization construction and a high degree of automation.
