Background technology
With society, rapid development of economy, the continuous quickening of urbanization process, the development and utilization of urban underground space
One of important directions as Chinese society sustainable development.The construction of underground transportation facilities enters Rapid development stage,
In the underground engineering Shield Construction Technique to receive much concern, earth pressure balanced shield obtains because of the advantages that applied widely, low cost
It is widely applied, turns into the main flow of tunneling technique.When being tunneled with earth pressure balance pattern, such as in layer of sand, gravel layer, especially
In the larger soil layer tunneling construction of grain particle diameter, because soil body viscosity is big, frictional force is big, water penetration is high and the poor fluidity of cutting soil
Etc. reason, enter the soil body to bury in storehouse and be easily compacted into the native slag of helical conveyer system, and be difficult to discharge.
Working region is filled into using the foaming agent of finite concentration, pressure and flow in subway work scene, is being excavated
During inject water, bentonite slurry or foaming agent, after being sufficiently stirred, can be improved the performance of the soil body, ensure
The mobility of the soil body, and the water penetration of the soil body is reduced, while cause excavation face to keep stable.Knife can also be reduced by filling foam simultaneously
The friction of disk and the soil body, moment of torsion is reduced, reduce the adhesion strength of housing and clay on cutterhead, be advantageous to casting mechanism and be unearthed, it is required
Driving power may be reduced by.
At present, for the foaming agent of China's subway shield tunnel construction mainly from external import, its price is higher, and domestic production
Shield foaming agent, usually in accordance with the formula of other field foaming agents such as light foam concrete, its stability is compared with import
Product also has a certain distance, and adaptability has limited.
