Description
Technical field
The invention belongs to Shield Construction Technique fields, and in particular to a kind of foam stabilizing persistent form Soil pressure balance shield foam agent and
Its preparation method.
Background technology
The development of transportation plays the role of China's expanding economy very important.Instantly subway, high ferro and most
The 4000km/h driving three-step-march plans closely proposed, all illustrate pursuit of the people to speed, also embody fireballing important
Property.
The subway vehicles indispensable as modern metropolitan cities are only popularized now in a line city, it is following with
The city expansion and the increase of the density of population in two wires and three line cities, subway must be as the standard configuration in city.
Product currently on the market, quality generally existing problem are used inferior materials and turned out substandard goods serious, with the thickening of no substantial role
Agent is adulterated, and is not drawn attention to the danger of shield-tunneling construction, it is therefore necessary to the development of shield technique is followed, into one
Step research and development debugging improves, and adapts to complex working condition and the update of equipment instantly.
The content of the invention
The technical problem to be solved by the present invention is to provide a kind of foam stabilizing persistent form Soil pressure balance shield foam agent and its preparations
Method solve thes problems, such as that existing foaming agent foam bubbles are generally bigger than normal, is tested by improvement, obtains with suitable thin
The foam of degree, and further extend the foam stabilizing time.
The present invention adopts the following technical scheme that a kind of foam stabilizing persistent form earth pressure balanced shield, EPBS steeps to solve above-mentioned technical problem
