Abstract
The invention discloses a composite additive adapted to a Guangdong coastal deep soft soil rapid pile-forming cement mixing pile. Corresponding to the mass ratio of cement in the cement mixing pile, the composite additive is prepared from, by weight, 2%-3% of silicon dioxide, 0.03%-0.05% of triethanolamine, 4%-6% of water glass, 0.25%-0.4% of sodium hydroxide, 1.5%-2% of FDN and 0.5%-1% of calcium chloride. By adopting the composite additive prepared through the formula, in the same age, the compressive strength of cement soil doped with the composite additive is improved by 30% or above relative to the additive-free cement soil strength, at the same strength, the age of the cement soil doped with the composite additive is shortened by 20% or above relative to the additive-free cement soil strength, the strength of a pile body is effectively improved, and meanwhile the pile-forming speed is increased.
Description
Technical field
The present invention relates to cement mixing pile art, referring in particular to one kind, to be adapted to the coastal Deep Thick Soft Ground in Guangdong Province quick
Pile cement mixing pile compound additive.
Background technology
Cement mixing reinforcement technique, as a kind of efficient method for processing foundation, at home and abroad obtains in all kinds of engineerings extensively
Use.But the land-based area weak soil in the clear trip in Coast of Guangdong Province Deep Thick Soft Ground Area, mostly littoral facies warp or navigation channel, has
Water content is high, void ratio is big, permeability is little, compressibility is big, shearing strength is low and the bad engineering properties such as sea water complicated,
And reinforcing body intensity that the cement under conventional match ratio and soil stirring are formed is low under briny environment, pile-forming speed is slow, engineering
The middle cement mixing pile match ratio that need to be adapted to Coastal Area of Guangdong Province Deep Thick Soft Ground, to increase strength of the mixing pile and to accelerate pile speed
Degree.
Content of the invention
In view of this, the present invention is directed to the disappearance of prior art presence, and its main purpose is to provide one kind to be adapted to Guangdong
Save coastal Deep Thick Soft Ground quick pile cement mixing pile compound additive, the existing cement mixing pile intensity of its energy effectively solving is not
Foot and the slow problem of pile-forming speed.
For achieving the above object, the present invention is using as purgation technical scheme：
One kind is adapted to the coastal Deep Thick Soft Ground in Guangdong Province quick pile cement mixing pile compound additive, and corresponding cement stirs
Mix the mass ratio of cement in stake, compound additive by weight percentage, including material composition have：Silicon dioxide 2%～
3%th, triethanolamine 0.03%～0.05%, waterglass 4%～6.5%, sodium hydroxide 0.25%～0.4%, FDN 1.5%～
2% and calcium chloride 0.5%～1%.
Preferably, described compound additive by weight percentage, including material composition have：Silicon dioxide 2%, three second
Hydramine 0.04%, waterglass 4%, sodium hydroxide 0.4%, FDN 1.5% and calcium chloride 0.5%.
The present invention compared with prior art has clear advantage and beneficial effect, specifically, by technique scheme
Understand：
By compound additive is obtained using inventive formulation, under identical age, mix the soil cement of compound additive
The relatively additive-free soil cement intensity of comprcssive strength improves more than 30%, under equality strength, mixes the cement of compound additive
Native age, relatively additive-free soil cement intensity shortened more than 20%, effectively increases strength of the mixing pile and also accelerates pile-forming speed simultaneously.
Specific embodiment
The present invention discloses one kind and is adapted to the coastal Deep Thick Soft Ground in Guangdong Province quick pile cement mixing pile compound additive, phase
The mass ratio of cement in corresponding cement mixing pile, compound additive by weight percentage, including material composition have：Titanium dioxide
Silicon 2%～3%, triethanolamine 0.03%～0.05%, waterglass 4%～6.5%, sodium hydroxide 0.25%～0.4%, FDN
1.5%～2% and calcium chloride 0.5%～1%.During use, by silicon dioxide, triethanolamine, waterglass, sodium hydroxide, FDN
And calcium chloride mix homogeneously is then added in cement.
Stir the reinforcing body intensity being formed for the cement under conventional match ratio and soil in Coast of Guangdong Province Deep Thick Soft Ground Area
The slow problem of low, pile-forming speed, spy passes through test of Proportional Ratio, makes the water being adapted to Coastal Area of Guangdong Province Deep Thick Soft Ground
Mud mixing pile match ratio, to increase strength of the mixing pile and to accelerate pile-forming speed.Indoor characteristics of soft clay and water analysis situation such as table 1 He
