Shield excavation technology is the frontier technology in non excavation, is non excavation method in the construction of a fully mechanized construction method, shield excavation method is the use of shield machine in underground excavation, in the protection of the shield, in the tunnel excavation and lining of the Nene safety operation, so as to make the tunnel construction method the. In the process of shield machine advancing in the ground, to prevent tunnel collapse through the shield wall and the supporting body support around the wall, at the same time in front of the excavation face with cutting equipment for mining soil, through the earth moving machine will be out of the soil outside the tunnel, the pressure exerted on the rear jacking jack, forming a tunnel structure, smooth excavation.
Non excavation shield mud purification system refers to the soil excavation down by the shield machine, cutting the gravel into the warehouse, the high density slurry after mixing the slurry by the pump to the mud circulation system, in the mud treatment system for processing and then back to the pump excavation face, so the cycle.
The shield construction field water treatment system is an important guarantee for the normal driving of shield machine, processing system must be no danger of anything going wrong in the shield construction, achieve 100% reliable.
Mud separation system is divided into two parts, the first part of the mud separation and treatment separation system, the second part of the cyclone separation system.
The separation and treatment separation system of mud is to separate and process the slurry formed by the shield cutting soil sand, then pump the recovered mud into the adjusting tank. It is more suitable to use drilling fluid vibrating screen as primary separation. The role of vibrating screen is to pre treat the mud, remove the coarse particles such as mass and lump. The separation of coarse particles with multi-layer vibrating screen, to meet the classification of particles, the screen particles of different sizes through the vibrating screen of different specifications, to meet the requirements of the site use mud particles, particles in the process is larger than the screen mesh is excluded to the system, through the sieve slurry into the slurry tank.
Product recovery system function is mainly used for mud purification recovery, do not have storage mud and mixed mud function, need additional configuration storage tank and mixing slurry equipment. |
