Abstract
The invention provides a foaming agent for protecting a cutter head and reducing wear of the cutter head, which is used for lubricating a soil body and lowering the torque of the cutter head. The quality of the foaming agent is good. The foaming agent comprises sodium lauryl sulfate, amine oxide, water and sodium butylnaphthalenesulfonate. The foaming agent provided by the invention can improve the soil body, enhance the compressibility of the soil body, ensure the establishment of soil pressure, replace the moisture and prevent spouting. The product is stable.
Description
Technical field
The present invention relates to a kind of engineering materials, relate in particular to a kind of energy and produce actual tensio-active agent or the whipping agent of surfactant.
Background technology
In shield machine with soil pressure balance for construction, except only a few stratum (being similar to the silt clay layer in Shanghai), do not need to carry out soil improvement, most of stratum all need to carry out effective soil improvement and ensure carrying out smoothly of construction.Wherein whipping agent is a kind of very effective soil improvement agent, and nearly all stratum all needs to assist with foam the construction of earth pressure balanced shield.Foam is the foam produced after being mixed by a kind of special whipping agent, water and pressurized air.Foam is mainly by with after the mixing of the soil body as the improved materials of the soil body: the sandy soil foam for rich water can squeeze away the free water in the soil body, and the supporting role that relies on foam improves stream plasticity and the sealing of the excavation soil body, thereby improve the stream plasticity control earth mud lining of the soil body for the voidage that the high viscosity soil foam can increase the soil body.Whipping agent quality in the market also needs to improve on soil improvement.
Summary of the invention
The object of the invention is the problem existed for prior art, provides a kind of and protect cutterhead, reduces the whipping agent of cutterhead wearing and tearing, and for the lubricated soil body, reduction cutterhead moment of torsion, it is best in quality.
For reaching above-mentioned purpose, the present invention is achieved by following technical proposals:
A kind of whipping agent is characterized in that: component and the weight percent thereof of described whipping agent are as follows:
Sodium lauryl sulphate 8～27%
Amine oxide 5～19%
Water 41～67%
Dispersion agent 9～21%
Dispersion agent adopts sodium butylnaphthalenesulfonate.
The sticky foundation that can improve the soil body, increase the compressibility assurance soil pressure of the soil body of whipping agent of the present invention, replace moisture, prevent from gushing, and its product is stable.
Embodiment
For further understanding feature of the present invention, technique means and the specific purposes that reach, function, below embodiment the present invention is described in further detail.
A kind of whipping agent, each component and weight percent thereof are as follows:
Sodium lauryl sulphate 8～27% (Dow Chemical Industrial Co., Ltd)
Amine oxide 5～19%
Water 41～67%
Sodium butylnaphthalenesulfonate 9～21%.
When concrete preparation, each component and weight percent thereof are:
1, sodium lauryl sulphate 15%
2, amine oxide 15%
3, water 50%
4, sodium butylnaphthalenesulfonate 20%.
The use of whipping agent, at the volume of the required foam of shield engine foamed system:
Q
form＝FIR×Q
soil
＝FIR×A
face×V
The FIR--foam injects ratio, gets 30%;
Practical Project is given an example:
1, the injection rate of foam
| The ground type | The FIR representative value |
| Layer of sand | 30％－50% |
| Fine sand, sandy gravel stratum | 25％－35% |
| Clay | 25％－30% |
| Hard rock | 20％－35% |
| Soft rock | 50％－70% |
Shield structure diameter R is 6.3m, and stratum is that fine sand layer FIR(mixes ratio) get 30%
A
face--the excavation face area, get 31.2m
2
V--driving speed, get 0.06m
,
Q
form＝0.3×31.2×0.06=0.56 m
3/
min=33.7 m
3/h
2, the volume of required water
Q
water=Q
form* 97/1000=3.27 m
3/ h=3269 l/h=54.5 l/min
(extra large Rake shield engine configuration 8bar 133 l/min)
3, the volume of required stoste
Q
stoste=Q
form* 3/1000=0.101 m
3/ h=101 l/h=1.7 l/min
(extra large Rake shield engine configuration 9bar 5-300 l/h)
4, now select the transport capacity of pump
Pressure P=7 bar
Flow Q=12 m
3/ h=200 l/min
The 2nd and the flow of the 3 two and be 56.2 l/min, extra large Rake shield engine is configured to 138 l/min.
Therefore, its ability of pump of existing configuration is enough, and is greater than extra large Rake shield engine configuration.
Air bubble agent is the soil improvement product designed for shielded construction specially.
Product feature: colourless transparent liquid, product indices meet Montreal Convention, environmental friendly product.
Main technical details:
Outward appearance: micro-yellow transparent liquid
Proportion: 1.02 ± 0.5
pH 20℃ : 7.0±0.5
Product is containing harmful composition, but still should carry out labour protection, spill when ground, should note anti-skidding.
Above illustrated embodiment is only as conveniently illustrating the present invention, not the present invention is done to any type of restriction, have and usually know the knowledgeable in technical field under any, if in the scope that does not break away from technology provided by the present invention, example is executed in the equivalence that utilizes disclosed technology contents to do modification, and break away from technical characterictic content of the present invention, all still belong in the scope of the technology of the present invention feature.
